Problems solved by technology

[0004] However, the production process of the existing tile adhesive is an emulsion polymerization process. In the latex obtained by general emulsion polymerization, the latex particle size is relatively large, the coating effect is poor, and the adhesive force cannot meet the needs of large tiles.

preparation example Construction

[0044] like figure 1 Shown, in one embodiment, the preparation method of described small particle size large-slab brick adhesive in the above-mentioned embodiment is provided, a kind of preparation method of small particle size large-slab brick adhesive comprises the following steps:

[0045] Step 110, preparing polymerized styrene-acrylic emulsion.

[0046] Specifically, each component is weighed according to the weight of the desired polymerized styrene-acrylic emulsion, and then the weighed pure water, the styrene, the acrylic acid, the butyl acrylate, the methyl methacrylate Esters and the hydroxyethyl methacrylate are put into the In the polymerization reactor, heat while stirring, add emulsifier for pre-emulsification, the emulsifier is ammonium oleate, potassium oleate, ammonium stearate, potassium stearate, triethanolammonium oleate, polyoxyethylene alkanes any one or any combination of polyoxyethylene alkylaryl esters, sodium dodecylbenzenesulfonate, sodium lauryl s...

Embodiment 1

[0056]Said pure water, said styrene, said acrylic acid, said butyl acrylate, said methyl methacrylate and said hydroxyethyl methacrylate according to 33%, 10%, 0.5%, 20%, The ratio of 15% and 1.5% is put into the polymerization reaction kettle, heated while stirring, and the emulsifier is added for pre-emulsification, and then the initiator, buffer and activator are added to the pre-emulsion for polymerization reaction to obtain a copolymer , and finally the copolymer is cooled and filtered to obtain a polymerized styrene-acrylic emulsion with a fine particle size.

[0057] The obtained 870 parts of polymerized styrene-acrylic emulsion, 80 parts of deionized water, 1 part of multifunctional additive, 1 part of thickener and 3 parts of preservative were mixed and stirred evenly, sealed and preserved to obtain component A. 4 parts of silane coupling agent are subpackaged, sealed and stored to obtain component B, and mixed according to the weight ratio between component A and com...

Embodiment 2

[0060] Said pure water, said styrene, said acrylic acid, said butyl acrylate, said methyl methacrylate and said hydroxyethyl methacrylate according to 53%, 15%, 2%, 25%, The proportions of 20% and 5% are put into the polymerization reactor, heated while stirring, adding an emulsifier for pre-emulsification, and then adding initiator, buffer and activator to the pre-emulsion for polymerization to obtain a copolymer , and finally the copolymer is cooled and filtered to obtain a polymerized styrene-acrylic emulsion with a fine particle size.

[0061] 930 parts of polymerized styrene-acrylic emulsions obtained, 100 parts of deionized water, 4 parts of multifunctional additives, 6 parts of thickeners and 12 parts of preservatives, 20 parts of modified epoxy resins by weight, mixed Stir evenly, seal and preserve, and make A component, described modified epoxy resin comprises: bisphenol A type epoxy resin, unsaturated polyester resin and polyphenylene sulfide, and the weight ratio ra...

Abstract

The invention provides a small-particle-size large-plate ceramic tile binder and a preparation method thereof. The special small-particle-size large-plate ceramic tile binder prepared by mixing a component A and a component B according to a certain proportion is good in overall melting dispersion of a system; a small-particle-size polymerized styrene-acrylic emulsion serves as a base material, anda variety of macromolecular chemical auxiliary agents are supplemented; a silane coupling agent is hydrolyzed to form a siloxy group and an organic functional group; the siloxy group is combined withan inorganic interface, and the organic functional group is combined with an organic interface, so an organic matrix-silane coupling agent-inorganic matrix combined layer is formed; thus, the bondingfirmness coefficient of ceramic tiles is greatly improved; the drawing force is higher than 2560 N; the drying time is short; a formed film is high in mechanical strength; and good aging resistance,water resistance, high and low temperature resistance and acid and alkali resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of chemical building materials, in particular to a small-diameter large-slab brick adhesive and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for the beauty of building houses. Ceramic tiles are the first choice for people to improve the beauty of building houses. When ceramic tiles are bonded, special adhesives are needed to meet the requirements. However, traditional Mortar cannot meet the strict requirements of the tile paste process. When traditional mortar is used for tile paste, the adhesive force can only prevent the tile from falling off the wall surface, but it cannot prevent the tile from collapsing downward due to its own weight, and the mortar on the back of the tile is uneven. Coating can also easily lead to hollowing under the tiles, which is easy to fall off, and there is a great potenti...
