Redispersible Polymer Powder£¨RDP/VAE) FOR Tile Glue

Redispersible latex powder can provide tile adhesive with the ability to adapt to stress and deformation, that is, improve the flexibility of tile adhesive. In this system, the rigidity of tile glue is mainly provided by inorganic materials such as cement and sand, while the flexibility is provided by rubber powder. Polymer interpenetrates in the pores of cement paste to form a polymer network, which becomes an elastic link between rigid components and makes it flexible. When deformation occurs, the polymer network can absorb stress, ensuring that the rigid components will not be cracked and damaged. Therefore, it is very important to improve the flexibility of bonding materials to reduce hollowing. The proper amount of rubber powder can improve the state that the polymer inside the tile glue forms a network structure. In addition, a reasonable aggregate-cement ratio (the ratio of polymer to inorganic cementing material) should be selected to ensure the balance between the rigidity and flexibility of the bonding material. In this respect, the types and brands of cement can also be screened.
