Redispersible Latex Powder C-9080


胶粉 Shan State Redispersible Powder Latex Powder C-9080

-VeoVa 或乙烯或丙烯酸酯等二元或三元的共聚物,经过喷雾干燥得到的改性乳液粉末,它具有良好的可再分散性,与水接触时重新分散成乳液,并且其化学性能与初始乳液完全相同,即水份蒸发后可以形成膜,这种膜具有高柔韧性、高耐候性和对各种基材的高粘结性。 Shanbang redispersible latex powder is a modified emulsion powder obtained by binary or ternary copolymer of vinyl acetate and vinyl tert-carbonate- VeoVa or ethylene or acrylate, etc. Redispersibility, redispersed into an emulsion when contacted with water, and its chemical properties are exactly the same as the original emulsion, that is, a film can be formed after the water is evaporated. This film has high flexibility, high weather resistance and good resistance to various substrates. High adhesion. In addition, the latex powder with hydrophobic properties can make the mortar very waterproof.

Redispersible latex powder is mainly used for: interior and exterior wall putty powder, tile adhesive, tile jointing agent, dry powder interface agent, exterior wall external insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar for external insulation In mortar. All of the mortars are used to improve the brittleness and high elastic modulus of traditional cement mortars, and to give them better flexibility and tensile bond strength to resist and delay the generation of cracks in cement mortars. Because the polymer and mortar form an interpenetrating network structure, a continuous polymer film is formed in the pores, which strengthens the bonding between the aggregates and blocks some of the pores in the mortar. Therefore, the modified mortar after hardening has better performance than cement mortar. There has been a great improvement.

The role of latex powder in dry powder mortar is mainly the following aspects

   提高砂浆的抗压强度和抗折强度。 1 Improve the compressive strength and flexural strength of the mortar.
   乳胶粉的加入提高了砂浆的延伸率从而提高了砂浆的抗冲击韧性,同时也赋于砂浆良好的应力分散作用。 2 The addition of latex powder improves the elongation of the mortar and thereby improves the impact toughness of the mortar. At the same time, it also gives the mortar good stress dispersion.
   提高了砂浆的粘结性能。 3 improves the bonding performance of the mortar. The bonding mechanism is based on the adsorption and diffusion of macromolecules on the sticky surface, and the permeability of the rubber powder, and the cellulose ether fully wet the surface of the base material, so that the surface performance of the base layer and the new plaster is close, thereby improving the adsorption To greatly increase its performance.
   降低砂浆的弹性模量,提高变形能力,减少开裂现象。 4 Reduce the elastic modulus of the mortar, improve the deformation ability, and reduce cracking.
   提高砂浆的耐磨性。 5 improve the abrasion resistance of mortar. The improvement of abrasion resistance is mainly due to the presence of a certain amount of glue on the surface of the mortar. The glue powder plays a bonding role, and the omentum structure formed by the glue powder can pass through the holes and cracks in the cement mortar. Improves the adhesion of the base material to the cement hydration product, thereby increasing the abrasion resistance.
   赋予砂浆优良的耐碱性 6 Gives mortar excellent alkali resistance

Packaging and storage:

    It should be stored in a cool and dry place. The recommended period of use is twelve months. After opening the bag, please use it as soon as possible, otherwise you need to seal the bag to avoid absorbing moisture from the air. 25kg 袋。 / Bag.
