The redispersible latex powder for putty powder is a powder adhesive made from a special emulsion after spray drying. This kind of powder can be quickly restored to emulsion after contacting with water in water, and has the same properties as the initial emulsion. The product performance of redispersible latex powder for putty powder:
After the redispersible latex powder special for putty powder is mixed with the water in the mortar, it will be emulsified and dispersed in water to form a stable polymer emulsion. After the redispersible latex powder is emulsified and dispersed in water, the water will evaporate and form polymer in the mortar The film can improve the performance of the mortar, and different redispersible latex powders have different effects on the dry powder mortar.
Improve the impact resistance, durability and wear resistance of the 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, it will produce relaxation without being destroyed. The polymer film can be permanently present in the mortar system.
Improve the workability of mortar construction. There is a lubricating effect between the polymer powder particles, so that the mortar components can flow independently. At the same time, the rubber powder has an inductive effect on the air, giving the mortar compressibility and improving the construction workability of the mortar.
Improve the bonding strength and cohesion of mortar After the redispersible latex powder as an organic binder is formed into a film, it can form high tensile strength and bonding strength on different substrates. It plays an important role in the adhesion of mortar to organic materials (EPS, extruded foam board) and smooth surface substrates. The film-forming polymer rubber powder is distributed throughout the mortar system as a reinforcing material to increase the cohesion of the mortar.
Improve the weather resistance of mortar, freeze-thaw resistance, prevent mortar cracking Putty powder special redispersible latex powder belongs to thermoplastic resin, has good flexibility, can make mortar cope with external cold and hot environment changes, and effectively prevent mortar from being damaged by temperature difference change and crack.
