Ceramic tile adhesive

Abstract

The invention relates to a ceramic tile bonding material, in particular to a tile adhesive. It is composed of the following parts by weight: 35-55 parts of cement, 15-25 parts of quartz sand, 3-6 parts of heavy calcium carbonate, 0.5-3 parts of starch ether, 5-8 parts of early strength agent, water retention thickener 2-16 parts, 2-8 parts of redispersible latex powder, 5-10 parts of thixotropic lubricant, 5-12 parts of water reducer, 3-9 parts of retarder, 2-4 parts of anti-pantherine agent, basalt 8-10 parts of stone fiber, 45-60 parts of water. The tile adhesive provided by the present invention can effectively improve the phenomenon of yellowing and shedding caused by efflorescence on the surface of ceramic tiles by adding an anti-efflorescence agent. The addition of dispersible latex can make the raw materials mix evenly and seal the gaps as much as possible. The fiber further improves the bonding force and flexibility between the tiles. The added water-retaining agent can maintain the moisture balance before the tiles. The retarder and water-reducing agent improve the quality of the cement, and the waterproof ability of the tile adhesive is too high.

Description

technical field [0001] The invention relates to a ceramic tile bonding material, in particular to a tile adhesive. Background technique [0002] Brick adhesive is a very common bonding material used in building decoration and decoration projects. It is often used to paste ceramic tiles, mosaics, stones, etc. However, due to the high alkali content of ordinary Portland cement, traditional cement-based tile adhesives are prone to efflorescence, which affects the overall appearance of the building. It will rise and fall off, causing harm to the life safety of people and animals. [0003] Although there are many tile adhesive products on the market, some tiling projects, especially exterior wall tiling projects, even if the thin-layer method and tile adhesive products are used, they still remain after several years of use. A very important reason for the hollowing and falling off of the tiles is that the heat-resistant adhesive strength and flexibility of the tile adhesive are...

[0003] Although there are many tile adhesive products on the market, some tiling projects, especially exterior wall tiling projects, even if the thin-layer method and tile adhesive products are used, they still remain after several years of use. A very important reason for the hollowing and falling off of the tiles is that the heat-resistant adhesive strength and flexibility of the tile adhesive are not good, that is, when the tiles expand with heat and contract with cold in different temperature fields, the tile adhesive lacks sufficient adhesive strength. Strength and flexibility cannot well release the internal stress caused by thermal expansion and condensation of tiles, which eventually leads to small cracks between the tile adhesive and the tiles. These cracks will gradually form hollows after accumulating to a certain number, and lead to final fall off
