    Styrofoam coated with incombustibles and its manufacturing method {STYROTOAM COATED NONCOMBUSTIBLE AGENT AND ITS MANUTALTURING METHOD}
    [1] The present invention relates to a styrofoam coated with a non-flammable agent and to a method of manufacturing the same by applying a non-flammable coating agent on the surface of the building styrofoam to minimize the generation of toxic gases and to delay combustion speed.
    [2] In general, styrofoam, widely used as a building insulation material, is a combustible material, which causes rapid ignition in the event of a fire and generates a large amount of toxic gas.
    [3] Recently, various kinds of non-combustible or flame retardant interior materials have been developed to prevent large accidents in case of fire.
    [4] Looking at the non-combustible interior materials developed in the prior art as follows.
    [5] Korean Patent Publication No. 99-84110, "Method of manufacturing non-combustible building materials", "Synthesis and mixing clay in a proportion to make a solid mixture; administering a mixture of tin and the solid phase to a ball mill and pour water 1 Mixing sufficiently over time to obtain a slip, forcibly discharging the slip from the ball mill and transferring it along a pipeline into a slip tank installed near the ball mill and storing it in the slip tank with uniform stirring; Charging the vermiculite or mica, which is a main material separately from the slip, into the quantitative feeder, introducing the slip from the slip tank into the kneader and introducing the vermiculite or mica from the quantitative feeder into the kneader and then slipping the slip in the kneader. Sufficiently mixing and evacuating the vermiculite or the mica; Transporting the mixed mixture in the molding machine to a molding machine, cutting the molded product to a predetermined length, and drying the same by using 80-120% dry hot air; drying the dried product in a furnace at 850-1100 ° C. Firing at a temperature of 18 hours, and then inspecting the fired product and packaging and shipping the same to sequentially manufacture non-combustible building materials.
    [6] However, this selection has to go through several processes in order to manufacture the non-combustible building materials, causing a rise in manufacturing costs. Furthermore, the products manufactured by the above-described invention are used for the insulation, and thus cannot be applied to all the products of the building interior materials, and thus, all interior materials have to be manufactured in a separate method. In addition, in the case of the existing building, since it is necessary to replace the non-combustible interior materials after discarding the combustible interior materials, it is not only uneconomical but also left unattended from the risk of fire due to the burden of cost.
    [7] In addition, Korean Patent Publication No. 98-9174, "Board for interior and exterior decoration of non-combustible buildings and its manufacturing method", "Sawdust or sorghum powder and a small amount of coloring agent in activated clay, calcium sulfate, calcium silicate, magnesium or magnesium chloride, etc. The mixed water or the mixed water with the composition of the same ingredient to form a paste mixture, and then the glass fibers on the continuous glass plate, aclipan, polycarbonate plate, polyvinyl chloride plate or polypropylene plate After passing through the sandwich roller while pressing the paste mixture layer up and down, they are compressed to a certain thickness to obtain a predetermined mixture sheet. The surface is then smoothed with an epoxy resin layer, and then the adhesive layer, transfer film layer, and UV curable water are placed thereon. The laminated layer and the protective film layer are sequentially laminated to manufacture a nonflammable board.
    [8] However, this selection is also applied to a specific product of the interior and exterior boards, the use of the product is not only limited, and the manufacturing process of the product is complicated, so that the cost is increased and the use is avoided.
    [9] In addition, there is a "non-flammable fire-retardant coating composition" of Korean Patent Publication No. 96-4463, this selection is sodium silicate having a property of expansion and expansion by heat, titanium oxide as a white pigment, when foamed to protect the foam film by hardening the film It is composed of a suitable amount of polyethylene diamine and water mixed.
    [10] However, this selection has the effect of delaying the combustion rate of the combustible material, but it is not possible to suppress the generation of toxic gas, and thus, it is not possible to prevent the human injury caused by the toxic gas at the beginning of the fire.
    [11] The present invention has been researched and developed in order to solve the above problems, there is a technical problem to be able to simply manufacture by coating a non-flammable agent on the surface of the styrofoam used for construction.
    [12] Another technical problem of the present invention is to apply a nonflammable agent to a surface in a state where an existing flammable styrofoam is installed so as to prevent human and economic loss from fire without discarding the existing styrofoam.
    [13] Another technical problem of the present invention is not only to delay the combustion speed of the styrofoam during the fire, but also to minimize the generation of toxic gas, so that it is possible to suppress the initial fire while minimizing the casualties.
    [14] The present invention is prepared by coating the surface of the styrofoam after mixing the incombustibles pulverized into small particles in a liquid mixed solvent in order to delay the ignition in the fire and to suppress the generation of harmful gases.
    [15] The nonflammable agent is 70 to 80% of silicon oxide (SiO 2 ), 10 to 15% of aluminum oxide (Al 2 O 3 ), 3 to 5% of iron oxide (Fe 2 O 3 ), and calcium oxide (CaO) 2 to 4%, magnesium oxide (MgO) 2 to 4%, sodium oxide (Na 2 O) 3 to 5%.
    [16] The silicon oxide, which is often present in nature, is also called silica or silicic acid, and is a polycrystalline material and may have various types of crystal structures. In addition, it is widely used in refractory materials because of its high heat resistance and heat insulation.
    [17] The aluminum oxide is present in a lot of natural state and exists in a state of being combined with other elements such as iron, oxygen, and silicon. When bauxite is reacted with hot sodium hydroxide in the Bayer method, aluminum in the ore becomes sodium aluminate, and aluminum hydroxide is precipitated from the aluminate solution after removal of the insoluble substances. After that, the aluminum hydroxide is concentrated and calcined (calcining) to produce aluminum oxide, because it forms an oxide film on the surface has excellent corrosion resistance and non-toxic.
    [18] The iron oxide, magnesium oxide, and sodium oxide have good heat resistance, respectively.
    [19] The non-combustible material is pulverized into fine particles having a particle size, that is, a particle size of 250 to 400 mesh, and then mixed in a mixed solvent.
    [20] The mixed solvent may optionally be used, such as an aqueous solution to which a vegetable adhesive such as starch is added or an aqueous solution to which an adhesive resin is added.
    [21] The nonflammable agent is applied to the surface of the combustible Styrofoam in a mixed state in a mixed solvent in a thickness of 0.05 to 0.8 mm, and when applied and dried, the nonflammable agent is coated in a solid state.
    [22] When the non-flammable agent coated Styrofoam is ignited by its combustible material at the time of fire, the ignition is delayed by the non-flammable agent and the generation of toxic gas is minimized. That is, when heat is applied to the styrofoam, not only the primary combustion is delayed by the non-flammable agent coated on the surface, but also the solidified non-flammable agent is powdered and adsorbed to the styrofoam, which is a combustible material, to block the supply of oxygen, and As it is combusted, the adsorption power of the multi-process is converted into a powder, so that the toxic gas generated when the styrofoam is combusted is adsorbed by the powdered nonflammable agent and is prevented from being released to the outside.
    [23] Hereinafter, the present invention will be described in detail by the manufacturing process as follows.
    [24] Nonflammable Manufacturing Process
    [25] After grinding silicon oxide (SiO 2 ), aluminum oxide (Al 2 O 3 ), iron oxide (Fe 2 O 3 ), calcium oxide (CaO), magnesium oxide (MgO) and sodium oxide (Na 2 O) in the shredder The fine particles are separated by the net. The particle size of the fine particles is preferably 250 to 450 mesh.
    [26] Each material pulverized into fine particles is 70 to 80% of silicon oxide, 10 to 15% of aluminum oxide, 3 to 5% of iron oxide, 2 to 4% of calcium oxide, 2 to 4% of magnesium oxide, and oxidation 3 to 5% of sodium is added to a blender and mixed to prepare a nonflammable agent.
    [27] When the silicon oxide is less than 70% of the mixture, the heat resistance is lowered, if it exceeds 80%, the adhesive strength is reduced when mixing with the mixed solvent and then coated on the styrofoam 70 to 80% to the total weight It is preferable.
    [28] When the amount of the aluminum oxide is less than 10%, the efficiency thereof is lowered, and when the amount exceeds 15%, the amount of mixing of other materials, that is, silicon oxide, is lowered. .
    [29] The iron oxide, calcium oxide, magnesium oxide and sodium oxide may be mixed or excluded as necessary, and may be included in the process of smelting natural ore in order to obtain silicon oxide and aluminum oxide.
    [30] Coating Process
    [31] The non-combustible material prepared in the above process is added to the mixed solvent to prepare a coating agent.
    [32] The mixed solvent is prepared by dissolving a vegetable starch having an adhesive component in water or dissolving an adhesive resin in water.
    [33] The present invention is not limited to the components of the mixed solvent, and may be selectively used from the known ones, but the following conditions are required.
    [34] The conditions of the mixed solvent are first; Good affinity with styrofoam, second; To be nonflammable, third; No or minimal generation of harmful gases upon heating; fourth; Transparent or colorless or white.
    [35] A liquid coating agent is prepared by adding and mixing the non-flammable agent to the mixed solvent. The mixing ratio of the non-flammable agent is 25 to 45% as the total weight ratio, and the mixing ratio of the mixed solvent is 15 to 70% as the total weight ratio. .
    [36] If the mixing ratio of the nonflammable agent is less than 25%, the drying time is delayed and the required coating thickness cannot be obtained. If the nonflammable agent is more than 45%, the fluidity is lowered, so that the coating is not evenly applied during the coating operation. It is preferable to add 25 to 45% as the total weight ratio of the coating liquid.
    [37] Coating process
    [38] The coating prepared in the above process is to adhere to the surface of the styrofoam.
    [39] First, the coating agent is applied to the surface of the styrofoam, and such a coating method may be selectively used in a method of applying directly by a brush, spraying by air pressure, or immersing a material in a coating liquid and then drawing it out.
    [40] Building interior material coated with coating removes moisture contained in coating material by hot air drying method, and it is put into drying furnace and dried for 2 ~ 6 hours under the condition of 60 ~ 80 ℃ to remove moisture. The outer surface is laminated with a coating layer.
    [41] The thickness of the coating layer is preferably 0.05 to 0.80 mm, and can be repeatedly applied and dried to obtain the desired thickness. That is, since the coating thickness is about 0.2 to 0.4 mm when the primary coating agent is applied, a coating layer having a relatively thick thickness may be manufactured by applying the coating agent again in a fixed state after drying.
    [42] If the thickness of the coating layer is less than 0.2mm, the adsorption power of the harmful gas is not expected when the fire occurs, the role of the non-flammable agent can not be expected, the greater the thickness of the coating layer has the effect of delaying the ignition in the fire and the adsorption power of the harmful gas is greater, but the coating layer It is preferable not to exceed 0.8 mm because cracks are generated and the appearance is not good.
    [43] In order to test the efficacy of the coating agent prepared by the above-described manufacturing process, after coating the coating liquid to the thickness of 0.05 ~ 0.8mm on the surface of the styrofoam, the state of combustion by close to the heat is shown in Table 1.
    [44] Table 1
    [45] Time (sec) Coating Thickness (m / m)0 to 1 sec20-40 sec50 to 120 sec180 sec or more 0.08○△×× 0.15○○△× 0.45○○△× 0.80○○○△
    [46] (Method of measuring heat generation: visual inspection)
    [47] (No heat generation amount: ○, heat generation amount is not visually confirmed, but smell is confirmed: △, heat generation amount is visually confirmed: ×)
    [48] Specimen: 20mm thick styrofoam
    [49] In the present invention, as shown in Table 1, the greater the thickness of the coating layer, the less smoke generation, and the delayed ignition time increases the smoke generation amount. Therefore, in order to reduce the amount of harmful gas generated in the early stage of ignition, it is preferable to coat the thickness of the coating layer largely, and after a certain time after ignition, the generation of harmful gas increases.
    [50] As described above, the present invention is a coating treatment on the surface of Styrofoam, which is a building interior material, and in case of a fire, not only the combustion is delayed by the nonflammable agent contained in the coating agent, but also the generation of harmful gases is minimized, so that the fire is suppressed at the initial stage. Not only can you have the time to do it, but you can also minimize the casualties caused by toxic gases.
    [51] In other words, when the styrofoam starts to ignite, the coating agent coated on the surface is dissolved, and thus a nonflammable agent is attached to the ignition site to block the supply of oxygen, thereby delaying the combustion speed.
    [52] In addition, since the toxic gas generated when the styrofoam is burned is adsorbed by the porous powdered incombustibles, the generation of the toxic gas is suppressed as much as possible, thereby preventing the human injury caused by the toxic gas at the initial stage of the fire. .
    [53] The present invention can be applied to all products irrespective of the shape of the styrofoam, and can be simply applied to the existing installed flammable styrofoam surface to be converted into a flame retardant material.
    [54] In addition, the present invention is a beneficial invention that can double the effect by simply coating the coating liquid treated surface without maintaining a great aesthetic appearance of the existing styrofoam because it is maintained in a transparent or white.
