Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a low-elasticity tile adhesive, which solves the problem that ordinary tile adhesives have high cohesion and elasticity due to the addition of a relatively high amount of hydroxypropyl methyl cellulose ether. Good construction and kneading, not easy to stick flat, easy to hollow and other problems

Abstract

The invention discloses a low-elasticity tile adhesive, belonging to the field of tile adhesives. The low-elasticity tile adhesive is prepared from the following components in parts by mass: 300-500 parts of Portland cement, 0-100 parts of calcium powder, 0-200 parts of 30-100-mesh quartz sand, 200-400 parts of 100-180-mesh quartz sand, 0-10 parts of an early strength agent, 1-3 parts of hydroxypropyl methyl cellulose, 1-5 parts of guar gum ether, 0-2 parts of starch ether, 4-10 parts of a magnesium aluminum silicate thixotropic thickener and 5-20 parts of redispersible latex powder. According to the low-elasticity tile adhesive, the mixing amount of hydroxypropyl methyl cellulose is reduced, and the guar gum ether, the starch ether and the magnesium aluminum silicate thixotropic thickener are added, so that the cohesion and elasticity of tile adhesive slurry are greatly reduced when the primary excellent water retention capacity of the tile adhesive is guaranteed, the contradiction between the low elasticity and high water retention capacity is solved, the construction and the rolling are easy, the adhesion is flat, the hollowing is unlikely to occur, and the adhesion quality of tiles is improved.

Description

technical field [0001] The invention relates to a low-elastic tile adhesive, which belongs to the field of tile adhesives. Background technique [0002] Tile glue, also known as ceramic tile adhesive, is mainly used to paste decorative materials such as ceramic tiles, facing tiles, and floor tiles. Its main features are high bonding strength, water resistance, freeze-thaw resistance, good aging resistance and convenient construction. It is a very ideal bonding material. According to its composition, the products are divided into: cement-based tile adhesives, paste emulsion adhesives and reactive resin adhesives. Cement-based tile adhesives are currently the most commonly used materials for home decoration tiling. [0003] At present, in China, the cement-based tile adhesive construction cannot meet the flatness requirements of the wall surface, and the traditional tile paste method of back-adhesive method is still used. In order to achieve higher water retention and bondi...
