Product performance of redispersible latex powder
1. Improve the bending strength and flexural strength of mortar
The polymer film formed by the redispersible emulsion powder has good flexibility. In the gap and surface of cement mortar particles film, constitute a flexible connection. Thus, the brittle cement mortar becomes elastic. The mortar added with redispersible latex powder is several times higher in tensile flexural strength than ordinary mortar.
2. Improve the bonding strength and cohesion of mortar
The redispersible emulsion powder as an organic binder can form high tensile strength and adhesive strength on different substrates after film formation. It plays an important role in the bonding force between mortar and organic materials (EPS, extruded foam board) and smooth surface substrates. The film-forming polymer powder is distributed throughout the mortar system as a reinforcing material to increase the cohesion of the mortar.
3. Improve the impact resistance, durability and wear resistance of mortar
The rubber powder particles fill the cavity of the mortar, the density of the mortar increases, and the wear resistance is improved. Under the action of external force will produce relaxation without being destroyed. The polymer film can be permanently present in the mortar system.
4, improve the weather resistance of mortar, freeze-thaw resistance, to prevent mortar cracking
Redispersible latex powder is a thermoplastic resin, has a good flexibility, can make the mortar to deal with the external hot and cold environment changes, effectively prevent the mortar due to the change of temperature difference and cracking.
5. Improve the hydrophobicity of mortar and reduce water absorption
Re-dispersible latex powder in the mortar cavity and surface film, polymer film will not be secondary dispersion after water, to prevent the invasion of water, improve the impermeability. Special redispersible latex powder with hydrophobic effect, better hydrophobic effect.
6. Improve the workability of mortar construction
There is a lubricating effect between the polymer powder particles, so that the mortar components can flow alone, while the powder has an induced effect on the air, giving the compressibility of the mortar, improving the construction workability of the mortar.
