Common applications of dispersible polymer powders

The rubber powder is made of high temperature, high pressure, spray drying and homopolymerization with a variety of active-enhancing micropowders, which can significantly improve the bonding ability and tensile strength of the mortar. , outstanding heat aging performance, simple ingredients, easy to use, allows us to produce high-quality dry-mixed mortar. Common applications of dispersible polymer powders are:

Adhesives: tile adhesives, adhesives for construction and insulation panels;

Wall mortar: external thermal insulation mortar, decorative mortar;

Floor mortar: self-leveling mortar, repair mortar, waterproof mortar, dry powder interface agent;

Powder coatings: lime-cement plasters and coatings modified with putty powder and latex powder for interior and exterior walls and ceilings;

Filler: tile grout, joint mortar.

Redispersible latex powder does not need to be stored and transported with water, reducing transportation costs; long storage period, antifreeze, easy to store; small packaging volume, light weight, easy to use; It can be used as a premix modified with synthetic resin, and only need to add water when using, which not only avoids mistakes in mixing at the construction site, but also improves the safety of product handling.

In the mortar, it is to improve the weakness of traditional cement mortar such as brittleness and high elastic modulus, and to give cement mortar better flexibility and tensile bond strength 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 bond between the aggregates and blocks some of the pores in the mortar. Therefore, the modified mortar after hardening has better performance than cement mortar. has improved.

Dispersible polymer powder is dispersed into a film and acts as a reinforcement as a second adhesive; the protective colloid is absorbed by the mortar system (the film will not be destroyed by water after film formation, or “secondary dispersion”); film-forming polymer resin As a reinforcing material is distributed throughout the mortar system, thereby increasing the cohesion of the mortar.
