s2, adding the aqueous polyurethane dispersoid, the filler and the dispersant into a stirring device and stirring uniformly;
s3, adding the residual components into the product obtained in the step S2, and uniformly stirring to obtain the gum.
The tile back glue provided by the invention is prepared by taking the aqueous polyurethane dispersoid as a main film forming substance and adding the filler and other additives, and the environment-friendly single-component tile back glue is formed by film formation through volatilization and solidification of water, and has stronger binding power and better water resistance and weather resistance. When the adhesive is used, firstly, the back adhesive of the ceramic tile is coated and scraped to the back of the ceramic tile, then, the prepared cement mortar is coated on the back adhesive, and then, the ceramic tile can be paved.
The aqueous polyurethane dispersion is environment-friendly, nontoxic and ultralow in VOC, and can better meet increasingly strict VOC limitation; in the preparation process of adding the reactive silane coupling agent into the aqueous polyurethane dispersion, the molecular branched chain of the aqueous polyurethane has a coupling agent group, so that the back glue of the tile has stronger binding power, better water resistance and weather resistance, and excellent toughness and elasticity, and can effectively resist the shrinkage and deformation of a cement mortar layer; the aluminum tripolyphosphate contains polyphosphate radical ions, and the polyphosphate radical ions can permeate into pores of a cement base surface and are combined with metal ions in cement, so that the adhesive force between the tile back glue and the cement mortar can be further improved; the rice hull powder is used as a filler, so that the cost can be reduced, the rice hull powder is rich in silicon dioxide, the silicon dioxide is an excellent flow promoter, the convenience of the construction of the back glue of the ceramic tile can be improved, and the back glue can have compressibility after being formed into a film; the glass powder has small particle size, good dispersibility, good anti-settling effect and stable chemical property, has acid and alkali resistance, chemical inertia and super weather resistance, and can improve the weather resistance of the ceramic tile after the back glue is formed into a film; the asbestos powder contains powdery non-metallic materials of asbestos fibers, so that the water resistance of the back glue of the ceramic tile can be improved; dimethyl phthalate is used as a film forming aid.
