Problems solved by technology

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. On the other hand, wall materials such as hollow bricks, fly ash bricks, and aerated concrete are more and more widely used, and the water absorption and volume deformation of these wall materials are generally higher. Large, affecting the glue and stability of tiles, resulting in hollowing and cracking are extremely common and serious

Abstract

The invention discloses a low-alkalinity tile glue, which comprises the following components in parts by weight: 30 to 45 parts of cement, 40 to 60 parts of fine aggregate, 8 to 15 parts of filling material, 0.2 to 0.5 part of water-retaining and thickening agent, 0 to 0.1 part of starch ether, 1 to 3 parts of redispersable latex powder, 0.1 to 0.3 part of water reducer, 0.1 to 0.3 part of retarder, 0.1 to 0.4 part of salt-petering resisting agent, 0.1 to 1.0 part of fiber, and 15 to 22 parts of water. The tile glue has the advantages of low alkalinity, salt-petering resistance, good construction performance, high adhesive strength, cavity and cracking resistance, and slippage resistance.

Description

technical field [0001] The invention relates to a tile adhesive material, in particular to a low-alkalinity tile adhesive. Background technique [0002] Tile 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. On the other hand, wall materials such as hollow bricks, fly ash bricks, and aerated concrete are more and more widely used, and the water absorption and volume deformation of these wall materials are generally higher. Large, affecting the glue and stability of tiles, resulting in hollowing and cracking are extremely common and severe. Therefore, it is of great significance to develop a tile adhesive with low alkalinity and excellent comprehensive performance. [0003] Low-...
