In recent years, the invention of redispersible latex powder has made dry powder mortar significantly superior to traditional mortar in construction. By adding redispersible latex powder to dry-mixed mortar, the performance of cement or gypsum-based mortar can meet the needs of various constructions. Various properties of dry-mixed mortar can be significantly improved by adding redispersible latex powder, which can increase the amount of cement to achieve a binding effect.
The role of redispersible latex powder in dry-mixed mortar is mainly reflected in:
1. Improve the adhesion of dry-mixed mortar to various substrates to ensure the durability of mortar bonding strength under various conditions of use.
2. Reduce the elastic modulus of dry-mixed mortar, improve the elasticity and flexibility. The material can withstand the influence of certain substrate deformation, external impact, temperature deformation, freeze-thaw deformation.
3. Reduce the water absorption of the dry-mixed mortar, make the water-repellent effect more obvious, and reduce the damage caused by water and the dry powder mortar after molding.
4. Improve the anti-sagging performance and fluidity of dry-mixed mortar and improve the construction performance.
