In wet mortar, latex powder plays a very obvious role in improving the construction performance, improving the flow performance, increasing the thixotropy and sag resistance, improving the cohesion, extending the opening time, and enhancing the water retention.Because the latex powder has the high adhesive ability and the unique performance, such as: the water resistance, the construction property and the heat insulation property and so on, therefore, their application scope is extremely extensive.
Latex powder has a very outstanding waterproof performance, good bonding strength, increase the elasticity of mortar and have a long opening time, give the mortar excellent alkaline resistance, improve mortar adhesion, flexural strength, plasticity, wear resistance and construction, in the flexible anti-crack mortar has a stronger flexibility.
The specific role of latex powder is as follows:
1. After dispersing, latex powder forms film and plays a strengthening role as the second adhesive;
2, protect the colloid is absorbed by the mortar system (after the film will not be destroyed by water, or “secondary dispersion”);
3. Film-forming polymer resin is distributed as reinforcement material in the whole mortar system, thus increasing the cohesion of mortar.
