What are the functions of redispersible latex powder in cement mortar?

Redispersible latex powder The main functions of cement mortar are as follows:

1 Improve the tensile strength and flexural strength of cement mortar.

2 The addition of latex powder improves the tensile strength of cement mortar and thereby It improves the fracture resistance toughness of cement mortar and also gives cement mortar excellent in-situ stress dispersion effect.

3 improves the bonding performance of cement mortar. The bonding principle relies on the adsorption and diffusion of biological macromolecules on the adhesive surface. At the same time, the rubber powder has a certain degree of water permeability, and together with the cellulose ether, it can fully infiltrate the surface of the rural base material, making the rural base and the surface of the new batch of putty The characteristics are close to each other, thereby improving the adsorption force and greatly increasing its characteristics.

4 Reduce the elastic mold of cement mortar, improve deformation ability, and reduce Crack condition.

5 improves the wear resistance of cement mortar. The key to improving the wear resistance is the presence of a certain amount of rubber on the surface of the cement mortar. The rubber powder plays a bonding role, and the retinal structure formed by the rubber powder can overcome the holes and cracks in the mixed mortar. The bonding between the raw materials and the concrete solidification material is improved, thereby improving the wear resistance.

6 grants cement mortar acid resistance.

7 Improve the adhesion of putty powder, acid resistance and wear resistance performance, improve flexural strength.

8 Improve the moisture resistance and water permeability of putty powder.

9 Improve the water solubility of putty powder, increase the opening time, and improve the stickiness knotty.

10 Improve the tear resistance of putty powder and improve the use of putty powder performance.

Redispersible latex powder is made of polymer moisturizing emulsion through spraying It is made of a dryer. After being mixed with the water in the cement mortar, the emulsion is dispersed when it comes into contact with water, and a stable moisturizing emulsion is produced again. After the redispersible latex powder is dispersed in the water emulsion, the water evaporates, and the emulsion is evaporated in the cement. A polymer film is formed in the mortar to improve various properties of the cement mortar. Different redispersible latex powders have different effects on the dry powder mortar dryer.
