Redispersible latex powder
Redispersible latex powder is a powder adhesive made from vinyl acetate-ethylene copolymer emulsion spray-dried. This powder can be quickly redispersed into an emulsion after contact with water, and has the same properties as the initial emulsion, that is, a film can be formed after the water evaporates. This film has high flexibility, high weather resistance and resistance to various High adhesion to the substrate. In addition, the water-repellent latex powder can make the mortar have good water resistance.

Redispersible latex powder is mainly used in: internal and external wall putty powder, tile adhesive, tile jointing agent, dry powder interface agent, external wall thermal insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar and external thermal insulation dry In the mortar. In the mortar, it is to improve the brittleness and high elastic modulus of the traditional cement mortar, and give the cement mortar better flexibility and tensile bonding strength to resist and delay the generation of cement mortar cracks. Because the polymer and mortar form an interpenetrating network structure, a continuous polymer film is formed in the pores, which strengthens the adhesion between the aggregates and blocks some of the pores in the mortar. Therefore, the hardened modified mortar has better performance than cement mortar. There is a great improvement.
The main functions of "Mekai" redispersible latex powder in mortar are as follows:
1. Improve the compressive strength and flexural strength of mortar.
2. The addition of latex powder increases the elongation of the mortar, thereby improving the impact toughness of the mortar, and also imparts a good stress dispersion effect to the mortar.
3. Improve the bonding performance of the mortar. The bonding mechanism relies on the adsorption and diffusion of macromolecules on the sticky surface. At the same time, the rubber powder has a certain degree of permeability. Together with the cellulose ether, it can fully infiltrate the surface of the base material, so that the base layer and the new plaster have a similar surface performance, thereby improving Adsorbability greatly increases its performance.
4. Reduce the elastic modulus of the mortar, improve the deformability, and reduce the cracking phenomenon.
5. Improve the wear resistance of the mortar. The improvement of abrasion resistance is mainly due to the presence of a certain amount of glue on the surface of the mortar. The rubber powder acts as a bonding agent. The mesh structure formed by the rubber powder can pass through the holes and cracks in the cement mortar. Improve the bonding of the base material and the cement hydration product, thereby improving the wear resistance.
6 Give the mortar excellent alkali resistance.
The main functions of "Mekai" redispersible latex powder in putty are as follows:
1. Improve the adhesion and mechanical properties of putty.
2. Improve the cohesion of putty, excellent resistance, alkali resistance, abrasion resistance, and increase flexural strength.
3. Improve the waterproof and permeability of putty.
4. Improve the water retention of putty, increase the open time, and improve the workability.
5. Improve the impact resistance of putty and enhance the durability of putty.
