Redispersible latex powder is made of polymer emulsion by spray drying, mixed with water in cement mortar, emulsified and dispersed in water, and then regenerates a stable polymer emulsion. After redispersible latex powder is emulsified and dispersed in water, the water evaporates , Form a polymer film in the mortar, improve the properties of the mortar.
Which properties of mortar can be improved by redispersible latex powder?
1. Improve the impact resistance, performance and wear resistance of mortar
The mortar is filled with cement mortar pore cavity, the compactness of cement mortar is improved, and the wear resistance is improved. Under the action of external force, it can cause relaxation without being destroyed.
2. Improve the adhesion of mortar construction
The polymer powder particles have a wetting effect, so that the two components of the cement mortar can flow independently. In addition, the rubber powder has the effect of inducing gas.
3. Improve the bonding compressive strength and cohesive force of mortar
As an organic chemical adhesive, redispersible latex powder can produce high compressive strength and compressive strength on different boards. It plays a very important role in the bonding of cement mortar and organic chemical raw materials (stomach, extruded insulating foam board) and the surface of the cleaning board.
4. Improve the aging resistance of mortar, resist freeze-thaw cycles, and prevent cement mortar from cracking
Redispersible latex powder is a thermoplastic resin with good flexibility, which can make the mortar deal with damage caused by external heat and cold environments, and reasonably avoid cracks in the mortar due to temperature changes.
5. Increase the hydrophobicity of the mortar and reduce the moisture content
The redispersible latex powder is demulsified in the cement mortar cavity and surface layer, and the polymer paper is not easy to redisperse after water treatment, blocking water intrusion and improving impermeability.
