Cement-based tile adhesive is a new modern decoration material for pasting ceramic tiles, face tiles, floor tiles and other decorative materials.
Generally, cellulose ethers that provide water retention and thickening effects are added to tile adhesives, as well as latex powders that increase the adhesion of tile adhesives. The addition of latex powders can greatly increase the flexibility of tile adhesives, improve stress, and increase flexibility.
Such as hydroxypropyl methylcellulose, calcium formate, polyvinyl alcohol, styrene butadiene rubber powder, etc.
in addition,
Adding wood fiber can improve the crack resistance and open time of mortar;
Add modified starch ether to provide anti-slip performance of mortar;
Add early strength agent to make tile adhesive increase strength faster;
Hydrophobic agent is added to reduce water absorption to provide waterproofing effect.
In order to meet the needs of rapid construction and early completion, adding a certain proportion of amorphous calcium aluminate to the tile adhesive formula can achieve early strength, quick setting, rapid construction and rapid completion of the tile adhesive. Therefore, when the construction period is relatively tight, it can be used. To ensure fast construction, but also to achieve the effect of sticking tiles.
Cement-based tile adhesives added with amorphous calcium aluminate have the following advantages:
1. High bonding strength can be obtained in the early stage of bonding tiles with tile adhesive, and the setting speed is very fast;
2. The tile adhesive added with amorphous calcium aluminate has no loss in the later strength of the tile adhesive.
3. The tile adhesive added with amorphous calcium aluminate has obvious improvement in compactness, bonding strength, waterproof strength and crack resistance.
