The film of redispersible latex powder is elastic and tough, and it is in the rigid framework formed by the hydration of cement mortar. Between cement mortar particles and particles, it has a function similar to a movable joint, which can withstand high deformation loads, reduce stress, and improve tensile and bending resistance.
Redispersible latex powder improves impact resistance for thermoplastic resin. It is covered with a soft film on the surface of the mortar particles and can redisperse latex powder. It can absorb the impact of external force and relax without breaking, thereby improving the impact resistance of the mortar. Redispersible latex powder improves water repellency and reduces water absorption to improve the microstructure of cement mortar.
The polymer forms an irreversible network during cement hydration, and redispersible latex powder is added. Seal the capillary in the cement gel, block the absorption of water, prevent the penetration of water, and improve the impermeability. Redispersible latex powder improves abrasion resistance and durability.
The effect of dry cement mortar is remarkable. It can improve the bonding strength and cohesion of the material. Improve the elastic bending strength and flexural strength of materials. Improve the freeze-thaw resistance of materials. Improve the weather resistance of materials, and can redisperse latex powder. Durability, wear resistance. Improve the hydrophobicity of the material and reduce the water absorption. Improve workability and reduce material shrinkage. Can effectively prevent cracking.
