Redispersible latex powder cy-7120
Redispersible latex powder is a new type of building material controlled by -VeoVa and Niro system, which is imported from a vinyl acetate copolymer of two or three yuan of vinyl acetate or acrylic acid. It is imported from Danish company. The spray drying technology and equipment of Danish advanced Niro company are introduced by DCS. It has good redispersibility and is re dispersed into emulsion when contacted with water, and its chemical properties are exactly the same as that of the initial emulsion, that is, the film can be formed after evaporation of water. The membrane has high flexibility, high weatherability and high adhesion to various substrates. In addition, the latex powder with hydrophobicity can make the mortar have good water resistance.
Redispersible latex powder is mainly used in: putty powder for internal and external walls, tile binder, tile pointing agent, dry powder interface agent, external insulation mortar for external walls, self leveling mortar, repair mortar, decoration mortar, waterproof mortar external insulation dry mixed mortar. In order to improve the brittleness, high modulus of elasticity and other weaknesses of traditional cement mortar, the mortar is endowed with good flexibility and tensile bond strength to resist and delay the generation of cement mortar cracks. Because polymer and mortar form an interpenetrating network structure, a continuous polymer film is formed in the pores, which strengthens the bond between aggregates and blocks the sand Some of the pores in the slurry, so the performance of the hardened modified mortar is much better than that of the cement mortar.
Effect
It can be used as a second adhesive to strengthen the film;
● the protective colloid is absorbed by the mortar system (it will not be damaged by water after film formation, or "secondary dispersion";
● the polymer resin of film-forming is distributed in the whole mortar system as reinforcement material, thus increasing the cohesion of mortar;
In wet mortar
● improve construction performance; improve flow performance; increase thixotropy and sag resistance; improve cohesion; extend opening time; enhance water retention. Improve the tensile strength, flexural strength, modulus of elasticity, deformability, compactness, abrasion resistance, cohesive strength, carbonation depth, water absorption of the material after the mortar is solidified, and make the material have excellent water adding property (adding water adding rubber powder)
Advantage
It does not need to be stored and transported together with water to reduce the transportation cost; it has a long storage period, is antifreeze and easy to keep; the package is small in volume, light in weight and easy to use; it can be mixed with water binding agent to prepare a synthetic resin modified premix, which can be used only by adding water, which not only avoids mistakes in mixing at the construction site, but also improves the safety of product handling.
Packaging and storage:
It should be stored in a cool and dry place. It is recommended to use it for 12 months. After opening the bag, please use it once as much as possible. Otherwise, the bag mouth should be sealed to avoid absorbing water from the air. 25kg/ bag.
