It can be used in interior and exterior wall putty powder, tile adhesive, tile grouting agent, dry powder interface agent, exterior wall exterior insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar exterior insulation dry mixed mortar. In the mortar, the purpose is to improve the brittleness, high elastic modulus and other weaknesses of traditional cement mortar, and to give the cement mortar better flexibility and tensile bonding strength to resist and delay the occurrence of cracks in the cement mortar. Since the polymer and mortar form an interpenetrating network structure, a continuous polymer film is formed in the pores, which strengthens the bonding between aggregates and blocks some pores in the mortar. Therefore, the hardened modified mortar has better performance than cement mortar. There is a big improvement.
(1). Improve the compressive strength and flexural strength of mortar.
(2).The addition of latex powder increases the elongation of the mortar and thereby improves the impact toughness of the mortar. It also gives the mortar good stress dispersion.
(3).Improved the bonding performance of mortar. The bonding mechanism relies on the adsorption and diffusion of macromolecules on the sticky surface. At the same time, the rubber powder has a certain permeability and can fully infiltrate the surface of the base material together with the cellulose ether, so that the surface properties of the base layer are close to those of new plastering, thus improving the Adsorption properties greatly increase its performance.
(4).Reduce the elastic modulus of mortar, improve deformation ability, and reduce cracking.
(5).Improve the wear resistance of mortar. The improvement of wear resistance is mainly due to the presence of a certain amount of rubber on the surface of the mortar. The rubber powder plays a bonding role. The network structure formed by the rubber powder can pass through the holes and cracks in the cement mortar. The bonding between the base material and the cement hydration products is improved, thereby improving the wear resistance.
(6). Give the mortar excellent alkali resistance.
(7).Improve the cohesion of putty, excellent resistance, alkali resistance, wear resistance, and enhance flexural strength.
(8). Improve the waterproofness and permeability of putty.
(9).Improve the water retention of putty, increase the opening time, and improve workability.
(10). Improve the impact resistance of putty and enhance the durability of putty.
Redispersible latex powder is made from polymer emulsion by spray drying. After being mixed with water in the mortar, it is emulsified and dispersed when exposed to water to re-form a stable polymer emulsion. After the redispersible latex powder is emulsified and dispersed in water, the water evaporates. A polymer film is formed in the mortar to improve various properties of the mortar. Different redispersible latex powders have different effects on dry mortar.
