It is extremely necessary that the redispersible polymer powder is added to cement dry mortar products. It is very clear that improve the material's strength and cohesion of the adhesive. This is because the infiltration of polymer particles to the cement matrix and the capillary porosity, and to form a good cohesive strength results after the cement hydration. Also, because the polymer resin itself has an excellent adhesive strength, cement mortar play a more obvious role to improve the product adhesion to the substrate, in particular, such inorganic cement binder for wood, fiber, PVC, EPS, XPS viscosity of these organic substrates poor junction improvements.
Improve the bending and tensile resistance:
The polymer film that redispersible polymer powder forms among the space of the particles of cement mortar and on the surface has a very good flexibility, and forms flexible connectivity. And it can make the cement mortar resilience. It can withstand high loads not to deformate, and reduce stress, so making tensile and ant-bending improved.
Improve the impact resistance and wear resistance durability:
Redispersible polymer powder is a thermoplastic resin.The soft film coated surface of particles of the mortar can absorb the impact of external forces, relaxation and without damage, thereby enhancing the impact of the capacity of mortar. It makes compactness of mortar and combinability between the cement mortar and polymer membrane increased. Because of enhancing the bonding force, corresponding increase the mortar's ability to bear the shear stress, and deduce the wear rate, and improve wear resistance, and prolong the life of the mortar.
Improve the weather resistance and freezethaw resistance, reduce the formation of cracks:
Redispersible polymer powder, as thermoplastic resin, can prevent cement mortar material damage from thermal expansion and cool contraction that changing temperature differences cause. Not only to overcome the shrinkage deformation of cement mortar,and the shortcomings of easy to crack, but also to make materials flexible, thereby enhancing the lon-term stability of materials.
Increase the hydrophobicity to reduce water absorption:
Improve the microstructure of cement mortar added redispersible polymer powder. The polymer forms the formation of irreversible network during the cement hydration process, close the cement gel capillary, block the absorption of water, prevent water infiltration, and improve the impermeability capacity.
