Ceramic tile adhesive

Abstract

The invention relates to a ceramic tile bonding material, in particular to a ceramic tile adhesive. The ceramic tile adhesive is prepared from the following substances in parts by weight: 35 to 55 parts of cement, 15 to 25 parts of quartz sand, 3 to 6 parts of ground calcium carbonate, 0.5 to 3 parts of starch ether, 5 to 8 parts of early strength agent, 2 to 16 parts of water-retaining and thickening agent, 2 to 8 parts of re-dispersible latex powder, 5 to 10 parts of thixotropic lubricating agent, 5 to 12 parts of water reducing agent, 3 to 9 parts of retarder, 2 to 4 parts of whiskering-resisting agent, 8 to 10 parts of graystone fibers and 45 to 60 parts of water. The ceramic tile adhesive provided by the invention is characterized in that the whiskering-resisting agent is added, so that the phenomena of yellowing and falling caused by whiskering on ceramic tile surfaces can be improved effectively; re-dispersible latex is added for uniformly mixing raw materials, so that gaps can be enclosed as much as possible; the fibers are added, so that the bonding force and flexibility among ceramic tiles are improved further; moisture balance of the ceramic tiles can be kept by adding the water-retraining agent; the quality of the cement is improved by the retarder and the water reducing agent, so that the waterproofness of the ceramic tile adhesive is improved greatly.

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
