Redispersible Polymer Powder RDP by high temperature, high pressure, spray drying and a variety of activity enhanced powder are all together, can make the mortar significantly improve the bonding ability and its own tensile strength, falling resistance, water retention and thickening construction performance, water resistance, freeze-thaw resistance, heat aging performance outstanding, simple ingredients, easy to use. To disperse Polymer Powder RDP and cement has excellent fusion, skeleton can be completely dissolved in cement mortar paste, the strength of the cement, curing does not reduce both keep the adhesive effect, film-forming property and flexibility, but also has good corrosion resistance, stability and bonding performance and crack resistance, dry hind, can effectively prevent the erosion of acidic air on the wall, It is not easy to powdery and deliquescent after being subjected to moisture. It can improve the performance of mortar, improve the strength of mortar, improve the bonding strength of mortar and various substrates, improve the flexibility and variable line of mortar, compressive strength, flexural strength, wear resistance, toughness, adhesion and water retention ability, construction. In addition, Polymer Powder RDP with hydrophobicity can make mortar has good water resistance.
Redispersible Polymer Powder RDP is commonly used in
1, Tile adhesive: ceramic tile adhesive, building and insulation board adhesive;
2, wall mortar: external insulation mortar, decorative mortar;
3, floor mortar: self-leveling mortar, repair mortar, waterproof mortar, dry powder interface agent;
4, powder coating: interior and exterior wall and smallpox putty powder, Polymer Powder RDP modified lime-cement plaster and paint;
5, joint filling material: ceramic tile jointing agent, joint mortar.
The advantages of redispersible Polymer Powder RDP
1, do not need to be stored and transported with water, reduce transportation cost;
2, long storage period, anti-freezing, easy to keep;
3, small size, light weight, easy to use;
4, can be mixed with hydrocoagulable binder, with synthetic resin modified premix, use only add water can, which not only avoid mixing errors at the site, but also improve the safety of product handling.
The function of redispersible Polymer Powder RDP
In the mortar is in order to make the traditional cement mortar weakness such as brittleness, high elastic modulus of the improved, fu in cement mortar bond strength, good flexibility and tensile resistance and delay the cracks of cement mortar, because and mortar form interpenetrating polymer network structure, the pore formed in the continuous polymer membranes, strengthen the bond between aggregate, Blocked part of the pores in the mortar, so the hardening of modified mortar than cement mortar performance has a great improvement.
1, redispersible Polymer Powder RDP disperses into a film and plays an enhanced role as a second adhesive;
2, the protective colloid is absorbed by the mortar system (film will not be destroyed by water, or "secondary dispersion");
3. The film-forming polymer resin is distributed in the whole mortar system as reinforcement material, thus increasing the cohesion of mortar;
In repair mortar
Improve construction performance; Improve flow performance; Increased thixotropy and sag resistance; Improving cohesion; Extended opening hours; Enhance water retention.
After curing mortar
Improve tensile strength; Increase bending strength; Reduce the elastic modulus; Improve deformability; Increase material compactness; Increase wear resistance; Improve cohesion strength; Reduce carbonization depth; Reduce water absorption of materials; Make the material have excellent water increase (add water increase rubber powder).
