The function of redispersible emulsion powder in putty, mortar and tile glue

Chuangyao brand redispersible emulsion powder is used in putty powder for internal and external walls, ceramic tile binder, ceramic tile pointing agent, dry powder interface agent, external thermal insulation mortar for external wall, self leveling mortar, repair mortar, decorative mortar, waterproof mortar for external thermal insulation dry mixed mortar. In the mortar, in order to improve the brittleness and high elastic modulus of traditional cement mortar, it is better to give cement mortar Because polymer and mortar form interpenetrating network structure, continuous polymer film is formed in the pores, which strengthens the adhesion between aggregates and blocks some pores in mortar, so the performance of hardened modified mortar is greatly improved than that of cement mortar

1： The function of redispersible emulsion powder in putty is mainly as follows

1. Improve the mechanical properties and adhesion of putty. Redispersible latex powder is a powder binder made by spray drying of special emulsion (high polymer). After contacting with water, the powder can be quickly dispersed into emulsion and has the same properties as the initial emulsion, that is, the film can be formed after evaporation of water. The film has high flexibility, high weatherability and high adhesion to various substrates. In addition, the latex powder with hydrophobicity can make mortar have good waterproof property.

2. Improve the cohesion of putty, excellent resistance, alkali resistance, wear resistance, enhance the bending strength.

3. Improve the waterproof and permeability of putty.

4. Improve the water retention of putty, increase the opening time, improve the workability.

5. Improve the impact resistance and durability of putty.

2： The function of redispersible latex powder in mortar is mainly as follows

1. Improve the compressive strength and flexural strength of mortar.

2. The addition of latex powder improves the elongation of mortar, thus improving the impact toughness of mortar, and also gives the mortar good stress dispersion effect.

3. The bonding performance of mortar is improved. The bonding mechanism depends on the adsorption and diffusion of macromolecules on the adhesive surface. Meanwhile, the rubber powder has a certain permeability. It can fully infiltrate the surface of the base material together with cellulose ether, so that the surface performance of the base course is close to that of the new plastering, so as to improve the adsorption property and greatly increase its performance.

4. Reduce the elastic modulus of mortar, improve the deformation ability and reduce the cracking phenomenon.

5. Improve the wear resistance of mortar. The improvement of wear resistance is mainly due to the existence of a certain amount of glue on the surface of the mortar. The rubber powder plays a bonding role, and the mesh membrane structure formed by the rubber powder can pass through the holes and cracks in the cement mortar. The adhesion between the base material and the hydration products of cement is improved, so the wear resistance is improved.

6. The mortar is endowed with excellent alkali resistance.

3： Redispersible latex powder in the role of ceramic tile glue is the following aspects

1. With the increase of cement content, the adhesive strength of ceramic tile adhesive increases, at the same time, the tensile adhesive strength after soaking in water and the tensile adhesive strength after thermal aging also increase. The amount of cement should be more than 35%.

2. After thermal aging, the bonding strength of the adhesive increases with the amount of thermal aging adhesive.

At present, Shandong Zhiyou chuangyao Biotechnology Co., Ltd. has five production lines of 8000 tons / year hydroxypropyl methylcellulose (industrial grade), 3000 tons / year daily chemical grade hydroxypropyl methyl cellulose, 3000 tons / year hydroxypropyl starch ether, 2000 tons / year hydroxyethyl cellulose and 10000 tons / year redispersible latex powder. The products are widely used in building materials, coatings, synthetic resins, ceramics, daily chemicals, textiles, oil fields, plastics and other industries, with high technology content and high added value, so the market prospect is very broad.
