Internal and external wall putty powder, tile adhesive, tile pointing agent, dry powder interface agent, external thermal insulation mortar for external walls, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar external thermal insulation dry-mixed mortar.
In the mortar, it is to improve the brittleness, high elastic modulus and other weaknesses of the traditional cement mortar, and to endow the cement mortar with better flexibility and tensile bond strength, so as to resist and delay the generation of cement mortar cracks. Since the polymer and the mortar form an interpenetrating network structure, a continuous polymer film is formed in the pores, which strengthens the bonding between the aggregates and blocks some pores in the mortar, so the modified mortar after hardening is better than cement mortar. There is a big improvement.
The role of redispersible latex powder in putty is mainly in the following aspects:
1. Improve the adhesion and mechanical properties of putty. Redispersible latex powder is a powder adhesive made from a special emulsion (high molecular polymer) after spray drying. This powder can quickly redisperse into emulsion after contacting with water, and has the same properties as the initial emulsion, that is, it can form a film after water evaporates. This film has high flexibility, high weather resistance and resistance to various High adhesion to substrates. In addition, the hydrophobic latex powder can make the mortar very waterproof.
2. Improve the cohesion of putty, excellent resistance, alkali resistance, wear resistance, and enhance the flexural strength.
3. Improve the waterproof and permeability of putty.
4. Improve the water retention of putty, increase the open time, and improve workability.
5. Improve the impact resistance of putty and enhance the durability of putty.
2. The role of redispersible latex powder in tile adhesive is mainly in the following aspects:
1. As the amount of cement increases, the original strength of the tile adhesive increases. At the same time, the tensile adhesive strength after immersion in water and the tensile adhesive strength after heat aging also increase. The amount of cement should be above 35%.
2. With the increase of the amount of redispersible latex powder, the tensile bond strength after soaking in water and the tensile bond strength after thermal aging of the tile adhesive increase accordingly, but the tensile bond strength after thermal aging increases relatively obvious.
3. With the increase of the amount of cellulose ether, the tensile adhesive strength of tile adhesive after thermal aging increases, and the tensile adhesive strength after soaking in water first increases and then decreases. The effect is best when the cellulose ether content is around 0.3%.
When using redispersible latex powder, we should pay attention to the amount of use, so that it can really play its role.
