The redispersible emulsion powder is dispersed into a mold and acts as a second adhesive to play a bonding reinforcement; the protective colloid is absorbed by the mortar system (after being molded, it will not be broken. Or twice dispersed); the molded polymer resin is distributed throughout the mortar system as a reinforcing material, thereby increasing the cohesion of the mortar.

2. What is the role of redispersible latex powder in wet mortar?

Improve the construction performance; improve the fluidity; increase the thixotropic and anti-sagging; improve the cohesion; extend the opening time; enhance the water retention;

3. What is the role of redispersible latex powder after mortar curing?

Improve tensile strength; enhance bending strength; reduce elastic modulus; improve deformability; increase material compactness; enhance wear resistance; improve cohesive strength; reduce carbonization depth; reduce material water absorption; make the material have excellent hydrophobicity (add hydrophobic rubber powder).

4. What are the functions of redispersible latex powder in different dry powder mortar products?


The appearance of tile adhesive ensures the reliability of tile pasting to a certain extent. Different construction habits and methods have different construction performance requirements for tile adhesives. In the current domestic ceramic tile paste construction, thick paste method (traditional adhesive paste) is still the mainstream construction method. When this method is adopted, the requirements for ceramic tile adhesive are: easy to stir; Easy to apply glue and non-stick knife; The viscosity is better; Anti-slip is better. With the development of tile adhesive technology and the improvement of construction technology, the trowel method (thin paste method) has been gradually adopted. With this construction method, the requirements for tile adhesive are: easy to stir; good spreadability and non-stick knife; better anti-slip performance; better wettability of tiles and longer opening time.

① The effect of adding redispersible latex powder on the fresh mortar of tile adhesive:

A, extend the working time and adjustable time;

B, improve the water retention performance, to ensure that the cement water;

C, improve sagging resistance (special modified rubber powder)

D. Improve workability (easy to construct on the substrate, easy to press the tiles into the adhesive).

The effect of adding redispersible latex powder on the hardening mortar of tile adhesive:

A, and all kinds of substrates have good adhesion, including concrete, plastering, wood, old tiles, PVC;

B, in all kinds of climatic conditions, have good adaptability.
