    KLEBKRAFT VERST ARKJER FOR CEMENT COMPOSITIONS
    Background of the invention
    Field of the invention
    The present invention relates to material compositions and methods for increasing the cured bond strength, hardness and processability of cementitious compositions such as masonry cements and mortars.
    Description of the Related Art
    Masonry cements and mortars are hydraulically setting compositions especially made for use in joining bricks, blocks and the various components of wallcovering systems (hereafter referred to as "ETICS"). Such cements are typically mixed with a fine-grained aggregate and water prior to use. It is desirable that the wet mortar for manual processing have a high degree of moldability, as well as a relatively long working life before the cement cures.
    Masonry cements and mortars are made by grinding Portland cement and gypsum with about 20 to 65% of a third material such as limestone, lime, talc, pozzolans, clay, gypsum or combinations thereof. Portland cement is a type of cement which includes calcined oxides of calcium, aluminum, iron and silicon and is capable of solidifying under water. Such masonry cements are ground to a greater degree of fineness than most Portland cements intended for use in structural concrete. The finer grinding of wall cements improves the moldability of the finished mortar products.
    By "thermal insulation composite systems" or "ETICS" is meant any of a number of unique proprietary systems, each of which is specific

    Components that are associated with a particular ETICS manufacturer. A regular ETICS type known as "barrier ETICS" includes plate insulation, reinforcing adhesive, and outer coating arranged in three layers. A less common ETICS type, known as "drainage ETICS," may additionally include plastic edge strips, waterproof barrier layers, and water drainage cavities. The plate is typically foamed polystyrene or extruded polystyrene. One of the persistent problems with WD VS construction is building a durable and economical bond between masonry mortar and polystyrene.
    The innermost of the three barrier ETICS layers is typically a layer of foam insulation commercially available in the form of a polystyrene board. The inner surface of the polystyrene plate is in direct contact with a base adhesive (which may be a mortar) and receives mechanical fasteners such as nails or dowels.
    An intermediate adhesive paving layer (which may be a masonry mortar) is typically applied to the outer surface of the polystyrene sheet membrane using a trowel. The adhesive putty layer substantially surrounds and fills a reinforcing mat embedded in the adhesive putty layer. The mat is typically made of fiberglass and has approximately one-quarter square inch openings. Significantly, making the adhesive spatula, applying the adhesive putty layer to the outer surface of the polystyrene plate, and uniting the mat in the adhesive paving layer are generally considered to be demanding and time-consuming tasks for the skilled artisan.
    The outermost of the three layers is called a topcoat. It is usually made up of a colored and textured paint-like material (which may be a mortar), which is applied by a trowel, or less often by spraying. A wide range of colors and textures is available for the top coat. Available structures include smooth surfaces, coarse stucco-like structures, embedded stone chips, granite-like mixtures and brick-like treatments.

    Canadian Patent 491099, issued to Vitalis, describes dialkyl sulfosuccinate surfactant compositions prepared by spray-drying with sodium benzoate curing agent at 600-700 ° F in the form of dry non-caking water-soluble powders. However, the compositions of the '99 patent are not panaceas, and they are still capable of improvement because, inter alia, they contain sodium benzoate. One objection to the compositions of the '099 patent is that sodium benzoate absorbs water in a humid atmosphere and clumping and aggregation is expected when the ambient humidity exceeds 50%. Another objection to the compositions of the O99 patent is that sodium benzoate in a dry atmosphere is associated with skin and eye irritation.

    There is a need for an improved surfactant that is free-flowing under humid atmospheric conditions and quickly dissolves in water. Preferably, the new surfactant enhances the bond between masonry mortar and smoothes hydrophobic surfaces such as those used in ETICS. Ideally, the new surface-active solid increases the hardness and reduces the water absorption of masonry cements and mortars.
    SUMMARY OF THE INVENTION
    It has now been discovered that certain additives, hereafter referred to as tackifiers, may be used in cement-based mortars to improve the adhesive bonding force between the mortars and relatively hydrophobic plastic materials such as polystyrene. Adhesive enhancer additives can be broadly categorized as surfactants and include dialkyl sulfosuccinates and their salts. The tackifiers of the invention are free flowing solid compositions.

    DETAILED DESCRIPTION OF PREFERRED ASPECTS OF THE
    INVENTION
    In a preferred embodiment, the invention is a free-flowing, surface-active, solid composition useful as an adhesive enhancer for cement mortar, including a surfactant and carrier particles. Since the construction industry is well equipped to handle premixed mortars and cements that come to a construction site in powder form, the trickle quality of this tackifier is highly desirable.
    REPLACED -7- • * «♦ ♦ · * ·
    The surfactant includes one or more alkyl sulfosuccinates and / or one or more salts of alkyl sulfosuccinates. Preferably, the alkyl sulfosuccinates and the salts are dialkyl, more preferably dialkyl having a total of 16 to 32 alkyl carbon atoms per molecule. Dioctylsulfosuccinate, Didecylsulfosuccinat and their sodium or ammonium salts are particularly preferred. For the purposes herein, "alkylcarbon atom" means a carbon atom located in an alkyl ligand of a sulfosuccinate moiety.
    The surfactant is preferably present in an amount of from about 30 to about 75 weight percent based on the total weight of the surface active solids composition, more preferably from about 35 to about 65 weight percent, and most preferably from about 45 to about 55 weight percent.
    The carrier particles are composed of calcium carbonate, calcium silicate, silica, kaolin, or mixtures thereof. The carrier particles should have an average particle size of from about 0.1 to about 1000 microns, preferably from about 1 to about 200 microns, most preferably from about 10 to about 160 microns. A typical preferred particle size distribution includes 50% particles. 4 microns, 95% particles below 26 microns, and 100% particles below 56 microns.
    Carrier particles of less than 1 micrometer are not recommended for use in the invention as they cause dust problems and are sometimes associated with risks to human health. Also, these extremely small particles tend to settle out of mixtures with other solids rather than to distribute homogeneously, as is necessary for use in mortar and cement mixtures. Ideally, the surfactant solids composition is a particulate having the same particle size distribution as a mortar or cement to which it is added.
    The carrier particles are preferably present in an amount of from about 10 to about 75 weight percent based on the total weight of the surface active solids composition, more preferably from about 20 to about 60 weight percent, most preferably from about 25 to about 55 weight percent. The carrier particles have
    REPLACED -8- -8-
    Preferably, it is capable of having an amount by weight of the surfactant of from about 0.2 to about 5 times the weight of the carrier particles, more preferably from about 1 to about 4 times the weight of the carrier particles, most preferably about 1 to about 3 times the weight of the carrier particles to wear.
    The carrying capacity of the carrier particles is a scale factor for adjusting the rate at which the surfactant dissolves when a solid surfactant composition of the present invention is immersed in water or any other solvent. For chemical workers in general, and mortar and cement mixing construction workers in particular, relatively quick dissolution is highly desirable. Dissolving the surfactant from a carrier particle is usually faster with carrier particles having a lower carrying capacity. On the other hand, surface-active solid compositions in which the carrier particles have too low a bearing capacity tend to clump and aggregate as a trickle.
    As stated above, the carrier particles preferably have an average particle size of from about 0.1 to about 1.00 microns and the ability to support a weight amount of the surfactant of preferably about 0.2 to 5 times the carrier particles , In addition, the inventors found that suitable calcium carbonate carrier particles in this size range usually have a specific surface area of about 0.1 to 15 square meters per gram; suitable silica particles in this size range usually have a specific surface area of about 100 to about 600 square meters per gram. For calcium silicate, suitable carrier particles usually have a specific surface area of from about 100 to about 300 square meters per gram. In the case of kaolin, suitable particles usually have a specific surface area of up to 20 square meters per gram.
    In addition, the surfactant solid composition preferably includes a flow aid. For the purposes herein, "flow aid" means a material that tends to prevent agglomeration of certain solids, causing the
    SUBSEQUENT
    Free-flow of solids is promoted. Without being bound by theory, it is believed that anti-caking agents act by absorbing excess moisture or by coating particles, thereby rendering them water repellent. Examples of useful flow aids include calcium silicate, silica,
    Magnesium oxide, magnesium or calcium stearates, kaolin and bentonites. Some trickle aids can serve two or more purposes, such as absorbing liquids and promoting trickling. Hydrophobic silica is particularly preferred as a flow aid.
    The flow aid is preferably present in an amount of from about 1 to about 10 weight percent based on the total weight of the surface active solids composition, more preferably from about 4 to about 8 weight percent.
    In another preferred aspect, the invention is a dry blended, hydraulically setting mortar or cement composition. The squat mixed composition is in powder or granular form and includes a hydraulically dehumidifying, dry mixed mortar or cement; a surfactant composition as described above; as carrier particles described above; and a Rieselhilfe as described above. Preferably, the surface active solids composition includes from about 0.1 to about 1 weight percent, preferably from about 0.2 to about 0.8 weight percent, and more preferably from about 0.3 to about 0.7 weight percent alkyl sulfosuccinate and / or or salts of alkyl sulfosuccinates based on the total weight of the dry blended composition.
    The inventors discovered that the presence of from about 0.1 to about 1 weight percent of dioctylsulfosuccinates, didecylsulfosuccinates and / or salts of these sulfosuccinates in a dry blended composition of the invention compared the bond strength of a hydraulically setting mortar or cement made from the dry blended composition compared to hydraulically dehumidifying mortar or cement made from a dry blended composition that does not include dioctyl sulfosuccinates, didecyl sulfosuccinates and salts of these sulfosuccinates, but otherwise identical

    In yet another embodiment, the invention is a process for producing a free-flowing surface-active solid composition. The method includes incorporating a surfactant selected from the group consisting of alkyl sulfosuccinates, salts of alkyl sulfosuccinates and mixtures of these sulfosuccinates and / or salts in an absorption zone. The surfactant may be incorporated in liquid, solid or solute form in a liquid solution. Suitable surfactants are described above with respect to a surface active solid composition.
    Carrier particles are also introduced into the absorption zone. The carrier particles composed of an absorbent material selected from the group consisting of calcium carbonate, calcium silicate, silica, kaolin, and mixtures thereof, an average particle size of about 0.1 to 1000 microns, and the ability to add a weight amount of the surfactant of from about 0.2 to about 5 times the weight of the carrier particles, are introduced into the absorption zone. Such carrier particles are described above with respect to the surface-active solid composition.
    The surfactant and carrier particles are maintained in the absorption zone under conditions effective to absorb the surfactant by the carrier particles to produce a free flowing solid surface active agent composition. The effective conditions may include mixing, kneading agitating, or spray-drying the surfactant with the carrier particles. Preferably, spray drying of the surfactant with carrier particles will maintain effective conditions in the absorption zone. Optionally, a flow aid such as hydrophobic silica is introduced into the absorption zone where it is mixed with the surface active solid particles to promote flowability.
    SUBSEQUENT
    When effective conditions are maintained in the absorption zone for spray-drying the surfactant with the carrier particles, the surfactant is preferably introduced as a solute in an aqueous solution. A defoamer, a nonionic surfactant, or both can be mixed with the liquid solution. Preferably, a fluidized bed of surfactant solution droplets and carrier particles in the absorption zone is maintained at a temperature that is sufficiently cool to permit absorption of the solution into the carrier particles, and is sufficiently warm to concentrate the solution at an economically practical rate. The concentration at which the solution is introduced, the temperature at which the solution is introduced, the relative sizes and amounts of the solution droplets and carrier particles, and the empty tube velocity and inlet temperature of the fluidizing gas are factors in determining the effective conditions. These factors and techniques for their optimization are known to those skilled in fluidized bed spray drying.
    When conditions which are effective for concentrating a liquid surfactant by vacuum drying, rotary evaporator drying or similar drying techniques are maintained in the absorption zone, the surfactant is preferably incorporated as a sulfosuccinate solution or as a sulfosuccinate salt solution. The solution is preferably mixed with the absorbent carrier particles, kneaded, shaken or otherwise agitated. Additional ingredients such as a defoamer or a nonionic surfactant may be introduced directly into the absorption zone or via the sulfosuccinate salt solution into the absorption zone. It is possible to produce free-flowing surface-active solid particles without removing the entire solvent from the particles.
    In yet another preferred aspect, the invention is a method of forming an adhesive bond between a hydraulically setting cement mortar composition and an article composed of a polymeric plastic material. The polymeric plastic material may be composed, for example, of foamed polystyrene or extruded polystyrene and incorporated into a system such as a thermal insulation composite system.

    Performance Example 4: Testing of Spray Dried Bonding Force Enhancers
    The following performance test procedure (hereafter referred to as "test procedure") is performed to test the effect of a bond strength enhancer on an adhesive bond between a tester
    Cement composition and a composite of foamed or extruded polystyrene plate to determine. In the procedure, solids boosters are premixed with a dry cement composition for about one minute. In any event, the cement composition is selected from mineral adhesive and reinforcing mortars such as "BAUMIT Adhesivefiller ™" and "BAUMIT Adhesivefiller Allround ™" available commercially from Baumit. The mineral mortar is added to water in a ratio of 4 to 1 and mixed for one minute. In each experiment, a drug concentration usage level of 0.3 to 0.6 mass% dialkylsulfosuccinate salt is used.
    A 2 to 3 mm wet grout layer is uniformly applied to a sheet of foamed or extruded polystyrene, such as a foamed polystyrene XPS sheet, commercially available from BASF under the trademark "Styrodur 3035 CS.". The wet mortar test specimens are dried for a period of 7, 14 or alternatively 28 days. At the end of the drying period the bond strength of the bond between the mortar and the foamed polystyrene sheet is measured according to the test protocol DIN EN ISO 4624: 2003. A peel-off tester is used in the protocol. Each of the tests is generally of 6 to 10 times with a power amplifier of interest and at the same time the same number of times without any power amplifier for comparison

    Performance Example 5: Testing of Spray Dried Bond Adhesive Enhancers
    To determine the effect of usage level on bond strength, the test procedure described above in Example 4 for various use levels of a particular spray dried surfactant solid composition in a given mineral mortar on identical polystyrene plates is performed.
    In the procedure, a surfactant composition prepared by spray drying an aqueous solution of dioctylsulfosuccinate salt with a calcium carbonate carrier for about one minute is premixed with a dry blended, hydraulically setting cementitious mortar composition commercially available under the trade mark "BAUMIT Adhesivefiller Allround ™" from Baumit. The mineral mortar is added to water in a ratio of 4 to 1 and mixed for one minute. In each experiment, an active ingredient concentration utilization level in the range of 0, -1 to 8, 8% by mass dialkylsulfosuccinate salt is used. ,
    A 2 to 3 mm wet grout layer is uniformly applied to an extruded polystyrene board, commercially available from Dow under the name Austrothenn Top P. The wet mortar test specimens are dried for a period of 7 days. At the end of the drying period, the bond strength of the bond between the mortar and the extruded polystyrene sheet is measured according to the test protocol DIN EN ISO 4624: 2003 using a peel adhesion tester. An Adhesion Boost value (in units of percentage increase) is calculated by dividing the mean of the results for each booster test by the mean of the test results without booster, subtracting one and multiplying the difference by 100.
