It can be used in interior and exterior wall putty powder, tile adhesive, tile grouting agent, dry powder interface agent, exterior wall exterior insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar, exterior insulation dry mixed mortar. In the mortar, the purpose is to improve the brittleness, high elastic modulus and other weaknesses of traditional cement mortar, and to give the cement mortar better flexibility and tensile bonding strength to resist and delay the occurrence of cracks in the cement mortar. Since the polymer and mortar form an interpenetrating network structure, a continuous polymer film is formed in the pores, which strengthens the bonding between aggregates and blocks some pores in the mortar. Therefore, the hardened modified mortar has better performance than cement mortar. There is a big improvement.
(1): The main functions of redispersible latex powder in putty are the following aspects:
①. Improve the adhesion and mechanical properties of putty. Redispersible latex powder is a powder adhesive made from a special emulsion (polymer) spray-dried. This powder can be quickly dispersed into an emulsion after contact with water, and has the same properties as the initial emulsion, that is, it can form a film after the water evaporates. This film has high flexibility, high weather resistance and resistance to various high adhesion to the substrate. In addition, hydrophobic latex powder can make the mortar very waterproof.
②. Improve the cohesion of putty, excellent resistance, alkali resistance, wear resistance, and enhance flexural strength.
③. Improve the waterproofness and permeability of putty.
④. Improve the water retention of putty, increase the opening time, and improve workability.
⑤. Improve the impact resistance of putty and enhance the durability of putty.
(2): The main functions of redispersible latex powder in ceramic tile adhesive are the following aspects:
①. As the amount of cement increases, the original strength of the ceramic tile adhesive increases. At the same time, its tensile adhesive strength after water immersion and thermal aging also increase. The cement dosage should be above 35%.
②. As the amount of redispersible latex powder increases, the tensile bonding strength after water immersion and the tensile bonding strength after thermal aging of the tile adhesive increase, but the tensile bonding strength after thermal aging increases is more obvious.
③. As the amount of cellulose ether increases, the tensile bonding strength of tile adhesive increases after thermal aging, and the tensile bonding strength after water immersion first increases and then decreases. The best effect occurs when the content of cellulose ether is around 0.3%. When using redispersible latex powder, you must pay attention to the dosage to truly exert its effect.
