The redispersible latex powder is made from polymer emulsion by spray drying, mixed with water in cement mortar, emulsified and dispersed with water, and then regenerated stable polymer emulsion. After dispersing emulsion powder in water and emulsifying and dispersing, water evaporates and polymer film is formed in mortar to improve the properties of mortar.

What properties can redispersible latex powder improve?

1. Improve the impact resistance, performance and wear resistance of mortar

The cement mortar pore cavity is filled with cement mortar to improve the compactness and wear resistance of cement mortar. Under the action of external force, it can cause relaxation without damage.

2. Improve the adhesion of mortar construction

High polymer powder particles have wetting effect, which makes the two components of cement mortar flow independently. In addition, rubber powder can induce gas.

3. Improve the bond compressive strength and bond strength of mortar

As an organic chemical adhesive, redispersible latex powder can produce high compressive strength and compressive strength on different boards. For cement mortar and organic chemical raw materials (stomach, extruded insulation foam board) and clean board surface bonding played a very important role.

4, improve mortar aging resistance, freeze thaw cycle, prevent cement mortar cracking.

Redispersible latex powder is a kind of thermoplastic resin with good flexibility. It can make mortar deal with the damage of external thermal environment and cold environment, and reasonably avoid cracks caused by the change of temperature difference.

5. Increase the hydrophobicity of mortar, reduce the moisture content

The redispersible emulsion powder is demulsified in the cavity and surface layer of cement mortar, and the polymer paper is not easy to redisperse after water treatment, which blocks the invasion of water and improves the impermeability.
