Preparation method of composite wall protection slurry
The invention relates to a preparation method of composite wall protection slurry, and belongs to the technical field of wall protection materials. According to the invention, starch-based interpenetrating network polymer emulsion is used as a raw material to prepare the composite wall protection slurry, wherein the interpenetrating network polymer is formed by continuously interpenetrating a network formed by respectively crosslinking two polymers, and the interpenetrating polymer network is in a chemical-physical blending form. Polyacrylate emulsion is mixed with starch to prepare interpenetrating network polymer emulsion, so that the water resistance of the polymer in the slurry can be improved. Polyacrylate can form a film with good gloss and water resistance after being dried, and thefilm is firm in adhesion, not easy to peel off, flexible and elastic at room temperature, and good in weather resistance. Polyacrylate and corn starch are mixed to prepare the interpenetrating network polymer, which can effectively improve the dispersity of polyacrylate in slurry. The water resistance of corn starch can also be effectively improved by mixing polyacrylate and corn starch, so thatthe anti-seepage effect of the wall protection slurry is effectively improved.
本发明涉及一种复合护壁泥浆的制备方法，属于护壁材料技术领域。本发明以淀粉基互穿网络聚合物乳液为原料，制备一种复合护壁泥浆，互穿网络聚合物是由两种聚合物各自交联后所形成的网络连续地相互穿插而成的，互穿聚合物网络是一种化学‑物理共混形式，将聚丙烯酸酯乳液与淀粉混合制备互穿网络聚合物乳液，可以改善聚合物在泥浆中的耐水性，聚丙烯酸酯干燥后能形成光泽好而耐水的膜，粘合牢固，不易剥落，在室温下柔韧而有弹性，耐候性好，将聚丙烯酸酯与玉米淀粉混合制备互穿网络聚合物，可以有效提高聚丙烯酸酯在泥浆中的分散性，并且两者混合也能有效提高玉米淀粉的耐水性，从而有效提高护壁泥浆的防渗效果。
