China The Role of Rdp in External Wall Thermal Insulation Mortar

RDP(Redispersible latex powder) is made of polymer emulsion by spray drying, mixed with the water in the mortar, meet water emulsification and dispersion, re form stable polymer emulsion, it in the water after emulsification and dispersion, water evaporation, in the mortar to form a polymer film.
RDP enhances the cohesion of the mortar and the bonding force to the thermal insulation board in the external thermal insulation system of the external wall, and reduces energy consumption while keeping the thermal insulation. Insulation mortar products on the outer wall can achieve the necessary workability, flexural strength and flexibility, which can make the mortar products have a good bonding performance with a series of insulation materials and the base layer. At the same time, it also helps to improve the impact resistance and surface crack resistance.
