Anti-aging polymer cement waterproof coating and preparation method thereof

XIA LE / SHUAI MINMIN / WANG YAWEN

The invention relates to the technical field of polymer cement waterproof coating preparation, and discloses an anti-aging polymer cement waterproof coating and a preparation method thereof.The anti-aging polymer cement waterproof coating is composed of powder and liquid, and the powder is prepared from Portland cement, coarse whiting, gypsum, filler, tannic acid, a bactericide, a water reducing agent, an ultraviolet-proof material and an anti-cracking material; and liquid materials: polymer emulsion and an additive. According to the anti-aging polymer cement waterproof coating and the preparation method thereof, materials in the powder can react with active groups such as an epoxy group on a modified acrylate emulsion for crosslinking, so that the modified acrylate emulsion, a cement hydration product and a filler are combined more tightly, and the compactness of a waterproof film layer is improved; by adding the ultraviolet-proof material, ultraviolet rays can be reflected and refracted by utilizing the high refractivity of the material, the influence of illumination on the coating film is reduced, and the durability of the waterproof layer is improved.

本发明涉及聚合物水泥防水涂料制备技术领域，公开了一种抗老化的聚合物水泥防水涂料及其制备方法，由粉料和液料组成，包括以下原料：粉料：硅酸盐水泥，重钙，石膏，填料，单宁酸，杀菌剂，减水剂，防紫外线材料，抗裂材料；液料：聚合物乳液，添加剂。该抗老化的聚合物水泥防水涂料及其制备方法，通过粉料中的材料能够与改性丙烯酸酯乳液上的环氧基等活性基团反应交联，使得改性丙烯酸酯乳液、水泥水化产物以及填料之间结合得更加紧密，提高防水膜层的致密性，减少了涂料膜层开裂，保证了防水层的持久稳定，通过添加防紫外线材料，利用材料的高折光性可以将紫外线进行反射和折射，降低光照对涂膜的影响，提高防水层的持久性。
