Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a two-component polymer tile adhesive and its preparation method to solve the problems caused by thermal expansion and cooling of the existing adhesive after bonding tiles. If the shrinkage is too large, the stretching adhesion of the adhesive itself is not strong, which will easily lead to the problem that the tiles will fall off

Abstract

The invention discloses a two-component polymer ceramic tile adhesive which is prepared from two groups of mixtures, wherein an A group of mixture comprises hydroxypropyl methylcellulose, calcium formate and epoxy resin; a B group of mixture comprises an acrylate copolymer, benzene rubber powder and epoxy resin; the A group of mixture is prepared from the following components in parts by weight: 250 to 450 parts of cement, 35 to 55 parts of gravel, 5 to 30 parts of redispersible latex powder, 3 to 10 parts of hydroxypropyl methylcellulose, 4 to 10 parts of calcium formate, 10 to 20 parts of epoxy resin, 40 to 50 parts of water, 40 to 60 parts of an emulsion and 5 to 20 parts of cellulose. The invention also discloses a preparation method of the two-component polymer ceramic tile adhesive.According to the preparation method, epoxy resin is adopted to weaken the thermal expansion and cold contraction of the adhesive, so that the tensile cohesiveness of the adhesive is increased, and ceramic tiles are prevented from falling off; gravel is adopted, so that the mechanical occlusion effect between gravels is greater, the bonding strength is increased; and meanwhile, silica fume is doped, the interface compactness is improved, and the interface bonding strength is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a two-component polymer tile adhesive and a preparation method thereof. Background technique [0002] Tile adhesive, also known as tile adhesive or tile adhesive, is mainly used to paste decorative materials such as tiles, face tiles, floor tiles, etc. Tile adhesive is a substance that plays a bonding role between tiles and walls, floors, etc. It is required to have certain bonding strength, shear strength, efflorescence resistance, aging resistance and other properties. [0003] However, after the existing adhesives are bonded to the tiles, the adhesive itself has poor tensile adhesion due to excessive thermal expansion and cold contraction, which easily causes the tiles to fall off. SUMMARY OF THE INVENTION [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a two-component polymer tile adhesive and a preparati...
