The basic function of redispersible latex powder in tile adhesive:
1. RDP can improve the compressive strength and flexural strength of tile adhesive.
2. Form a film and play a reinforcing role as a second adhesive;
3. The protective colloid is absorbed by the mortar system (it will not be destroyed by water after film formation, or "secondary dispersion");
4. The film-forming polymer resin is distributed as a reinforcing material and distributed throughout the mortar system, thereby increasing the cohesion of the mortar;
5. The addition of re-dispersible latex powder improves the elongation of the mortar and thus improves the impact toughness of the mortar and also gives the mortar a good stress dispersion effect.
6. The redispersible latex powder reduces the elastic modulus of the mortar, improves the deformability, and reduces cracking.
7. Redispersible latex powder improves the adhesive properties of ceramic tile adhesive. The bonding mechanism is based on the adsorption and diffusion of macromolecules on the sticky surface. At the same time, the rubber powder has a certain permeability, and the surface of the base material is fully infiltrated with hydroxypropyl methyl cellulose ether, so that the surface performance of the base layer and the new plaster Close to, thereby improving the adsorption, and greatly increase its performance.
8. Redispersible latex powder improves the wear resistance of mortar.
9. Redispersible latex powder gives ceramic tile adhesive excellent alkali resistance
