Redispersible polymer powders are dispersions of polymer emulsions after spray drying. With its promotion and application, the performance of traditional building materials has been greatly improved, and the bonding strength and cohesion of the materials have been improved.
Redispersible latex powder is an important additive in dry powder mortar. It can not only improve the elasticity, bending strength and flexural strength of the material, but also improve the weather resistance, durability, wear resistance of the material, improve construction performance, and reduce shrinkage. rate, effectively prevent cracking.
Introduction of the role of redispersible latex powder in dry mortar:
◆Masonry mortar and plastering mortar: Redispersible latex powder has good impermeability, water retention, frost resistance, and high bonding strength, which can effectively solve the cracking and penetration between traditional masonry mortar and masonry. and other quality issues.
◆Self-leveling mortar, floor material: Redispersible latex powder has high strength, good cohesion/cohesion and required flexibility. It can improve the adhesion, wear resistance and water retention of the materials. It can bring excellent rheology, workability and best self-smoothing properties to ground self-leveling mortar and leveling mortar.
◆Tile adhesive, tile grout: Redispersible latex powder has good adhesion, good water retention, long open time, flexibility, sag resistance and good freeze-thaw resistance. Provides high adhesion, high slip resistance and good workability for tile adhesives, thin layer tile adhesives and caulks.
◆Waterproof mortar: Redispersible latex powder enhances the bonding strength to all substrates, reduces elastic modulus, increases water retention, and reduces water penetration. It provides products with high flexibility, high weather resistance and high water resistance requirements. The long-lasting effect of the sealing system with hydrophobicity and water resistance requirements.
◆External thermal insulation mortar: Redispersible latex powder in the external thermal insulation system of external walls enhances the cohesion of the mortar and the bonding force to the thermal insulation board, which can reduce energy consumption while seeking thermal insulation for you. The required workability, flexural strength and flexibility can be achieved in the external wall and external thermal insulation mortar products, so that your mortar products can have good bonding performance with a series of thermal insulation materials and base layers. At the same time, it also helps to improve impact resistance and surface crack resistance.
◆ Repair mortar: The redispersible latex powder has the required flexibility, shrinkage, high cohesion, and suitable flexural and tensile strength. Make the repair mortar meet the above requirements and be used for the repair of structural and non-structural concrete.
◆ Interface mortar: Redispersible latex powder is mainly used to treat the surfaces of concrete, aerated concrete, lime-sand bricks and fly ash bricks, etc., to solve the problem that the interface is not easy to bond and the plastering layer is empty due to the excessive water absorption or smoothness of these surfaces. Drumming, cracking, peeling, etc. It enhances the bonding force, is not easy to fall off and is resistant to water, and has excellent freeze-thaw resistance, which has a significant effect on simple operation and convenient construction.
Application field
1. Bonding mortar, tile adhesive: redispersible latex powder
Let the cement change its original properties, including both organic and inorganic substances, so as to achieve the best bonding effect.
2. Plastering mortar, rubber powder polystyrene particles, flexible water-resistant putty, tile grout: redispersible latex powder
Change the rigidity of the original cement, enhance the flexibility of the cement, and improve the bonding effect of the cement.
