Redispersible polymer powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymers, vinyl acetate/tertiary ethylene carbonate copolymers, acrylic copolymers, etc. agent, with polyvinyl alcohol as protective colloid. This powder can be quickly redispersed into an emulsion after contacting with water. Due to the high binding ability and unique properties of redispersible polymer powders, such as: water resistance, construction and heat insulation, etc., their The range of applications is extremely broad.
Performance characteristics
It has outstanding bonding strength, improves the flexibility of the mortar and has a longer opening time, endows the mortar with excellent alkali resistance, and improves the adhesiveness, flexural strength, water resistance, plasticity and wear resistance of the mortar. In addition to the construction property, it has stronger flexibility in the flexible anti-crack mortar.
Application field
1. External wall thermal insulation system: Bonding mortar: Ensure that the mortar firmly bonds the wall and the EPS board. Improve bond strength. Plastering mortar: to ensure the mechanical strength, crack resistance and durability of the thermal insulation system, and impact resistance.
2. Tile adhesive and caulking agent: Tile adhesive: Provide high-strength bonding for mortar, and give mortar enough flexibility to strain the different thermal expansion coefficients of substrate and ceramic tile. Filler: Make the mortar impermeable and prevent the intrusion of water. At the same time, it has good adhesion with the edge of the tile, low shrinkage and flexibility.
3. Tile renovation and wood plastering putty: Improve the adhesion and bonding strength of the putty on special substrates (such as tile surfaces, mosaics, plywood and other smooth surfaces), and ensure that the putty has good flexibility to strain the expansion coefficient of the substrate. .
Fourth, the internal and external wall putty: improve the bonding strength of the putty to ensure that the putty has a certain flexibility to buffer the effect of different expansion and contraction stresses generated by different base layers. Ensure that the putty has good aging resistance, impermeability and moisture resistance.
5. Self-leveling floor mortar: ensure the matching of the elastic modulus of the mortar and the resistance to bending force and cracking. Improve the wear resistance, bond strength and cohesion of mortar.
6. Interface mortar: improve the surface strength of the substrate and ensure the cohesion of the mortar.
7. Cement-based waterproof mortar: ensure the waterproof performance of the mortar coating, and at the same time have a good adhesion with the base surface to improve the compressive and flexural strength of the mortar.
8. Repair mortar: ensure that the expansion coefficient of the mortar and the base material match, and reduce the elastic modulus of the mortar. Make sure the mortar has sufficient water repellency, breathability and adhesion.
9. Masonry plastering mortar: improve water retention. Reduces water loss to porous substrates. Improve the ease of construction operation and improve work efficiency.
Advantage
It does not need to be stored and transported with water, reducing transportation costs; long storage period, antifreeze, easy to store; small packaging, light weight, easy to use; can be mixed with hydraulic binders to make synthetic resin modified The premix can only be used by adding water, which not only avoids mistakes in mixing at the construction site, but also improves the safety of product handling.
