    [0002] Procedure to manufacture an aseptic, decorative floor, made by hand with epoxy resin and recycled glass
    [0004] FIELD OF THE INVENTION
    [0006] The present invention relates to the construction sector, within the area of decorative floor coverings using recycled glass. The campaigns on how to use and reuse glass containers and recycle them for different uses is a measure to contribute to the protection of the environment, even though glass waste is less polluting than plastic. Some statistical data of the sector indicate that during 2017 more than 103 thousand metric tons of glass containers were recovered in the Central American region. Currently, glass waste accounts for around 7% by weight of total household waste. Its recycling entails numerous environmental benefits, among which we can point out that it reduces the use of resources such as raw materials, water and energy, the amount of waste generated is reduced, lengthening the life of landfills and decreases air pollution.
    [0008] One of the main characteristics of glass waste is that it is possible to reuse practically all the materials. In addition, unlike paper and cardboard, it does not lose any of its characteristics during recycling, so the material can be reused indefinitely.
    [0010] Directive 2008/98 / EC of the European Parliament and of the Council, of November 19, 2008 on waste, for example, establishes among the objectives for this type of waste that before 2020, it must be increased at least up to 50% overall of its weight the preparation for reuse and recycling of waste materials such as, at least, paper, metals, plastic and glass from household waste and possibly other sources to the extent that these waste streams are similar to household waste; However, there is still no global awareness regarding the economic and environmental advantages that the reuse of this raw material can bring to countries and therefore we lack national regulations that regulate this necessary measure to contribute to sustainable development.
    [0011] The technical solution proposed by the present invention refers to a process for manufacturing floors made by hand from recycled glass and epoxy resin.
    [0013] BACKGROUND OF THE INVENTION
    [0015] The floor is probably one of the most important and basic parts of any space and, as with other parts of our homes, there are many options for its manufacture. Currently within the continuous coatings that are used to cover surfaces such as floors, a number of materials are used within the so-called construction materials, as well as ceramic composites and more recently recycled materials.
    [0017] It is known that the building and construction sector in general is one of the most polluting sectors on the planet, responsible for 40% of CO2 emissions into the atmosphere, due to the high demand for fuel that this industry supposes. Also, they are the cause of the depletion of non-renewable resources, as a result of the unlimited extraction of raw materials. Fundamentally for this reason, modifying the materials and systems that we are going to resort to for the construction of our homes, using materials with a minimum environmental impact, without affecting the desired quality, constitutes an important innovative alternative with a great economic and environmental impact.
    [0019] The use of recycled glass also plays an essential role in curbing the effects of climate change and protecting natural resources. Every time we recycle a glass container, we give life to another exactly the same and we achieve:
    [0021] • Conservation of natural resources, by avoiding extracting sand, soda and limestone from nature.
    [0022] • Energy savings, since the temperature required to melt the recycled glass hull or calcine is lower than that required to melt raw material and its use as a substitute for other raw materials therefore generates economic benefits.
    [0023] • Reduction of significant volumes of CO2 emissions. Recycled glass, for example for the industry itself, implies that 20% less energy is required in its manufacturing process, due to fuel savings. In addition, the process emits less CO2 because the chemical process of dissociation of carbonated raw materials does not take place in the furnace, which does take place when the origin is the raw material.
    [0024] • Reduction of waste generated. It prevents these resources from ending up in the landfill as waste and polluting the environment.
    [0026] Floors in general can be classified according to the material used in their elaboration, in:
    [0028] • Natural stone floors. These include those in marble and granite.
    [0029] • Concrete floors. They are generally floors that guarantee to eliminate the risks of leaks. They can be placed on any surface and are cheaper than the previous ones
    [0030] • Ceramic floors. They offer a variety of designs and are long-lasting and easy to maintain. They are recommended in areas where there is a lot of traffic of people.
    [0031] • Wood floor. They are pleasant to the touch, resistant and are the most in demand, although they have a high cost.
    [0032] • Synthetic floors. They provide beauty and are easy to install, however, their useful time is shorter, especially if there is a lot of traffic.
    [0034] Studies, published in 2018 by the Spanish Society of Ceramics and Glass, have been carried out on the incorporation of glass waste into cement mortars in order to replace part of the aggregate and the ability to modify the properties of the final product was evaluated. . In recent studies carried out, the analysis of the modifications produced in a reference mortar 1: 3 (cement / sand) produces a partial replacement of sand by crushed domestic glass, in proportions of 25 and 50% by weight, whose Results have revealed sensitive differences in the samples, where a better performance is reflected for the materials that incorporated glass fractions in their composition.
    [0036] The use of epoxy resins in the manufacture of floors is also known in the state of the art, the application AU20132000439 "Pavement product that has regions of different recycled or renewable content" from ARMSTRONG WORLD IND. INC., Published 02-14-2013, for example, describes a flooring product comprising a heterogeneously patterned layer having multiple regions, in which two regions have different recycling content. The thickness of the design layer can be greater than the dimensions of the regions or these can also extend from the upper surface of the layer to the lower surface of the design layer. The heterogeneous layer can be composed of particles / chips Consolidated that may contain a polyester binder system with a renewable component.
    [0038] The patent application EP2002899 "Floor or wall covering made of recycled glass, method of application in situ and method for the manufacture of such a covering" by PACCAUD ALEXANDRE, published on 12-17-2008, describes a floor, wall or roof comprising: a mixture of recycled glass with a binder, which forms a porous material having roughness and filler material applied over dry porous material to fill roughness. The method described in this invention for the in situ application of floor covering comprises depositing the adhesion body on a surface on the floor, mixing recycled glass with a binder to obtain the porous material, applying the porous material obtained on the surface. It is proposed to pass a smoothing roll in a criss-cross manner over the porous material, dry the porous material, and flow the filler material to fill the rough edges of the porous material to the maximum until its highest surface is reached. This process begins with the preparation of a composition, which comprises mixing recycled glass with a binder by means of resin.
    [0040] The application UA8691 “Monolithic Decorative Floor” from LTD. LIABILITY COMPANY RES. AND, published 08-15-2005, describes a monolithic decorative floor comprising a concrete base, several layers of coating made of an epoxy binder polymer, and more than one reinforcing layer. The coating comprises a primer layer made of an epoxy polymeric agent, a crosslinking layer made of an aerosil-filled epoxy binder, plus a quarter-colored backing layer of sand and epoxy polymer with bonding agent, and a Clear epoxy varnish surface protective layer.
    [0042] Patent No. ES1176333 (ESTELLE CATALA. AGUSTIN JUAN), published on February 14, 2017, refers to the elaboration of a composite panel coating, which can be used for floors or coatings, being especially suitable for coating surfaces. passable or for decorative covering of exterior surfaces by means of parquet flooring. This coating is formed by the union of a core based on thermosetting resin, reinforced with fibers and wrapped in paper or decorative foil. In this proposal, the resin core is formed from a resin that can be selected from epoxy resin, polyester resin, vinyl ester resin, polyurethane resin, silicone resin, polyamide resin or phenolic resin; and the reinforcing effect materializes it with the addition of glass fibers, carbon, kevlar and natural fibers. It stands out in the development of this panel coating that other natural fibers can be used such as fibers from rice residues, specifically rice husk in a proportion of up to 20% by weight. The procedure requires placing in a mold in a SMC process at a temperature of 160 ° C and must undergo a subsequent curing process, by means of pressure at certain points in order to stabilize the final panels, which can be obtained by cross-cutting. . This coating uses other ingredients and the glass material used is mainly glass fibers.
    [0044] Patent No. ES2624313 (VOET HANS et al.) Published on July 13, 2017, generally refers to an expansion joint system suitable for incorporation into concrete structures, particularly concrete floors. The resins proposed in this case are thermosetting polymer such as polyester resins; epoxy resins; vinyl ester resins; phenolic resins; polyurethane resins; polyaspartic acid ester resins (in particular polyaspartic urea ester resins); and combinations thereof, noting that the thermosetting polymer resin must be substantially hardened to which are added particles having a Mohs hardness within the range of 3 to 9, preferably within the range of 5 to 8. In this case, the The amount of aggregate material that is proposed to be added is within the range of 40% to 90%, preferably 50% to 90%, by weight of the final manufactured product. The average size of the particles should preferably be within the range of 0.1 mm to 5 mm. The glass material that is proposed to be used is quartz sand together with other reinforcing fibers in a proportion of 1% to 10% by weight, to provide reinforcement that contributes to strength, but not to its surface hardness. These fibers are selected from glass fibers; carbon fibers; aramid fibers and combinations thereof.
    [0046] Patent No. CN101811833 (Nantong Baijindun Glass Products Co LTD), published on August 25, 2010, describes an anti-slip floor, prefabricated on a fiberglass base with organic and inorganic particles in its upper layer, kiln dried, It has a colored sealer, in its composition it uses river sand that is supposed to be extracted from quarries of river beds. This patent proposes an anti-slip surface, which comprises a glass substrate and the anti-slip layer fixed on the surface of the glass substrate by screen printing that is cured with a film of resins that constitutes a mixture of material in organic and inorganic particles that can be made of silicon carbide or aluminum oxide that make up the anti-slip granules. In this case, the glass material that is proposed is, specifically, Silicon carbide, which does not have the same physical properties of the glass material that is proposed in the patent application, and, in addition, represents an increase in the cost of the coating. The proposed resins are selected from amino, epoxy resins, and polyurethane resin preferably stands out, in a proportion of 40% to 80% in the mixture. Likewise, it includes a proportion of organic particles that can be organic resin or pellets of polypropylene urethane resin particles, in a proportion of 20% to 50% and in the same proportion inorganic particles, which can be chosen from silicon carbide. or aluminum oxide, always ensuring that in both cases the size of such particles constitutes a surface area of 40 to 150 mesh granules. In this order, the process for preparing the anti-slip coating from the mixture indicated in patent No. CN101811833, which contains the "glass substrate", refers to glass fibers to prepare the surface by spraying, applying a coating with Roller or curtain coating in one layer and then cured in the drying oven at heating temperature of 90-150 ° C, the heating time is 30-60 minutes and dried.
    [0048] Patent No. FR2773370 (RAPP GUY), published on July 9, 1999, aims to solve the technical problem with the composition of the coating in self-leveling coatings of surfaces in general, such as panels, containing glass beads, using a minimum of binders. A first aspect is the use of glass beads and their size and shapes. The coupling agent for the manufacture of surface coatings must be especially transparent or translucent and for this they select a coupling binder that can be organic or inorganic, preferably a resin is selected from among epoxy, acrylic, polyurethane, polyester, polyvinyl or a hydrocarbon resin; the translucent material is selected from a methacrylate resin or a binder type of magnesium The coupling agent is approximately 45% to 80%, preferably 65% to 75% by weight of the total composition of the surface layer of self-leveling final coating. The process comprises depositing at least one layer of a composition that is mixed at the time of application to the site, said composition comprising surface glass beads with a coupling agent, and a binder, the bonding agent, the bonding agent. Bonding is present in a concentration between about 10% and about 35%, it is preferably selected from a self-curing or self-curing binder or polymerizable or curable with a curing agent, in particular an epoxy resin, an acrylic or methacrylic resin, a polyurethane resin, a polyester resin, a polyurethane resin polyvinyl, a hydrocarbon, pseudo-bitumen translucent resin, and a magnesium-type binder and a setting accelerating or retarding agent.
    [0050] Based on the foregoing, the aforementioned applications and patents do not describe the elaboration of a monolithic decorative floor, which is based on the proposal of a personalized design of pieces of recycled glass, through a self-leveling procedure that achieves an aseptic floor with a walkable surface that is waterproof and slip resistant.
    [0052] Similarly, regarding patent No. CN101811833 A (Nantong Baijindun Galss Products Co LTD), there are marked differences with our patent application for an aseptic floor with recycled glass and epoxy resin since it consists of a floor with an antimicrobial aseptic smooth surface, made with glass aggregates and crushed crystals that are taken from landfills, which are emptied on-site without joints or marks, with a transparent sealant and an aseptic and antimicrobial transparent self-leveling sealer is used, without using aggregates from the river basin. Additionally, the discrepancies lie in the fact that there is a process of heating the adhesive layer to form a conductive film. When the surface coating is done directly after an alkali-resistant paste fiberglass fabric on the polyurethane coating surface is brushed to form slip on the floor of the sealing uniform layer, heat treatment is applied to drying, at temperatures of 140-155 ° C, in periods of time of 25-35 minutes, creating a security layer of 0.5-4 mm, the layer of security film on the surface of the adhesive that is fixed to the Alkali-resistant fiberglass layer for a multi-functional floor surface. In this case, given the particularities of the materials used to create this surface, a more complex finishing process by heating is required than the one proposed in the present application does not require. Likewise, the material for coating concrete surfaces of patent No. CN101811833 has quartz sand and glass fibers as glass material, which differs from our solution proposal in that the glass material that we propose to use It is recycled and ground glass, which, in addition to achieving floor covering surfaces with excellent properties and appearance, offers an environmentally friendly alternative to reusing a waste material.
    [0054] On the other hand, regarding patent No. FR2773370, the composition of the coating differs from the proposal of our application, in that it uses pearls of certain characteristics and dimensions and also uses other ingredients such as binder, a bonding agent and accelerator of the hardening process.
    [0056] DESCRIPTION OF THE INVENTION
    [0058] The present invention refers to a process for the manufacture of a decorative, aseptic floor, made by hand with epoxy resin and recycled glass. The process is carried out as follows:
    [0060] STEP 1. Recycling of crystals, elimination of edges, disinfected, dried, classified and packed.
    [0062] STEP 2. Previous scarification of the concrete floor.
    [0064] STEP 3. Application of self-leveling epoxy primer.
    [0066] STEP 4. Mixing crystals and epoxy in an electric mechanical mixer.
    [0068] STEP 5. Placing and leveling the glass and epoxy mixture on the floor.
    [0070] STEP 6. Finishing the floor with hand trowels or mechanical straighteners.
    [0072] STEP 7. When the floor has hardened, a new layer of epoxy resin will be applied to seal the pores.
    [0074] STEP 8. Once the pore sealer has dried, proceed to the final sealing with antimicrobial self-leveling epoxy.
    [0076] STEP 9. When the self-leveling epoxy has dried, a coat of high-traffic antimicrobial urethane is applied that can be matte or glossy.
    [0078] The aggregates used in the process are glass waste that is in the environment as pollutants. They have different origins and mostly correspond to non-reusable containers, most of them are products that are not manufactured locally and exporting to their market of origin for reuse is very expensive. Therefore, all these containers enter our environments and landfills as pollutants, only the bottles that pack products made at the national level are reused, but in the washing process normally many are they break down and go into the environment as non-recycled waste. It is for this reason that by constituting recycled glass a low-cost material, we propose it in the present invention as an aggregate to build floors since, in addition to constituting a construction process where costs are reduced and environmental impact is minimized, beauty is also achieved in the finish, a wide range of colors, hardness and an aseptic composition.
    [0080] DETAILED DESCRIPTION OF THE INVENTION
    [0081] STEP 1. Recycling of crystals, disinfected, dried, classified and packed.
    [0083] The glasses, once located in the warehouse, are subjected to a process of cleaning impurities (earth, wood, garbage, plastic, etc.), manually, without using machinery. Then they are washed with a recycled water system, disinfected and dried in the sun, achieving an environmentally friendly process, saving energy and without producing harmful gases to the environment. Once dry, they are grinded with a hammer mill, which leaves them dull and then they are classified by size using different sized sieves (0.6 mm sieves are used in the machine. to 4.5 mm) and by color, then packed for its different uses.
    [0085] After the process there is an insignificant amount of pieces of paper from the labels of the bottles and the crystals, equivalent in the range of 0.75 kg for each ton of crystals, which is thrown away. Indeed, it also remains as a residue, a dust that does not generate pollution, which is kept in the vacuum cleaner.
    [0087] STEP 2. Scarification of the concrete floor.
    [0089] In this step, the upper layer of the concrete floor is cut or grated up to 90% of the surface, which is cut using a polishing machine with No. 06 diamond points, which are used in concrete specifically, which are grating and breaking the surface of the floor until reaching a depth measurement of 2 mm, transforming the floor into rustic with a virgin surface.
    [0091] STEP 3. Application of self-leveling epoxy primer.
    [0093] To glue the aseptic, decorative floor, made by hand with epoxy resin and recycled glass to the base concrete floor, we applied a 100% solid epoxy primer to a yield of 20 mt2 per gallon (3.78 liters). The first thing that is done is the mixture of the two components of the epoxy resin, which, once mixed, are poured on the floor with a rubber pad, which leaves some lines on the floor, then a roller is used on the entire surface of the floor to uniform the thickness of the same, and cause the entire surface to be of equal thickness. Epoxy has the condition of being an element that has excellent adhesion to the concrete floor and will noble and perfectly bond the floor to the concrete base, thus eliminating the possibility of these floors rising.
    [0095] STEP 4. Mixing crystals and epoxy in an electric mechanical mixer.
    [0097] After placing the primer, and while it has not dried, the aseptic, decorative floor will be placed, made by hand with epoxy resin and recycled glass, mixing 1 volume of solid epoxy resin with 6 volumes of crystals, in a proportion of 60%, of size # 0 (0.6 mm to 1.9 mm) and 40% of size # 1 (1.9 mm to 4.5 mm). These materials go to a mixer and after two (02) minutes a homogeneous mixture is obtained that is poured on the floor on the first fresco.
    [0099] When you want floors with different shades of colors, they are separated on the surface, with a thin strip of aluminum, in the shape of an "L", which is placed on the floor. These strips are placed on the concrete floor after drawing the design on it, so that the aluminum strip would separate one color tone from the other, on the surface of the floor. Once the floor is dry, with the desired colors, it is finished because it would only remain as a separating element between one color and another, and only an aluminum line will be seen.
    [0101] STEP 5. Laying and leveling with the glass and epoxy mixture on the floor.
    [0103] This mixture of crystals and epoxy is watered with a metal dispenser or with a leveling ruler leaving an even layer on the floor, at a desired thickness of 5 to 6 mm.
    [0105] When you have the floor design in the plan, you proceed to draw it on the floor, dividing one color tone from another, with an “L” -shaped aluminum strip, which is placed on the surface of the floor. Once the aluminum strips are in place, a mixing machine is used to mix the epoxy and crystal aggregates, then pour them onto the floor, working one color tone at a time. Subsequently, the desired color is inserted.
    [0106] STEP 6. Finishing the floor with hand trowels or mechanical straighteners.
    [0108] Once the mixture of crystals and epoxy has been watered, it is finished with a stainless steel float or float or motor straighteners (electric, gasoline, air), for a period of up to three (03) minutes, to achieve a totally smooth surface and achieve The crystals are compacted, reducing air bubbles, obtaining a denser and therefore more solid floor.
    [0110] STEP 7. Once the floor has hardened, the epoxy will be applied to seal the pores.
    [0112] At this stage we have a smooth but porous floor, so the same epoxy that is used for mixing with the crystals is used. When placing it on the floor, the pores that remain between the crystals begin to cover, this is watered over the entire surface with a urethane rubber pad that can be smooth or serrated, 4 mm, so that it does not stain the floor, to a yield of 15 mt2 per gallon (3.78 liters) and is left at rest for a period of four (04) to (05) hours, depending on the temperature.
    [0114] STEP 8. Once the epoxy used in the pore sealing has dried, the final sealing is carried out, applying a self-leveling epoxy of two components, 100% solid, mixing, three parts of resin or part A, on the one hand, of hardener, or part B with antimicrobial additive (Floroseptic Additive, 3-Iodo-2-Propynyl Butyl Carbamate) to give the user the assurance that the floor finish is aseptic and antimicrobial, these additives are added to the epoxy and their function is to create an environment unfavorable for pathogenic microorganisms, the performance of this self-leveling agent is 10 mt2 per gallon (3.78 liters) watered with a 3 mm urethane toothed rubber pad and leveled with a 6 mm wool microfiber roll which is It will allow to dry for a period of four (04) to five (05) hours, depending on the temperature.
    [0116] STEP 9. Once the self-leveling epoxy has dried, a layer of antimicrobial urethane for high traffic is applied that can be matt or glossy, its performance is 40 mt2 per 3.78 kg / m3 (3.78 liters) and it is finished with 6 mm thick polyester roll. This urethane layer is non-slip in the presence of water, but there are specific conditions, such as a kitchen, where greater safety may be required when walking in wet areas or with a greasy component, which, if required, is required. You can add a powder called aluminum oxide to the urethane, which provides a roughness to the floor and greater resistance to wear.
