Flexible vinyl chloride-vinyl acetate-acrylic waterproof latex powder and preparation method thereof
The invention relates to the technical field of latex powder, and discloses flexible vinyl chloride-vinyl acetate-acrylic waterproof latex powder and a preparation method thereof, and the flexible vinyl chloride-vinyl acetate-acrylic waterproof latex powder is prepared from the following components: a vinyl chloride-vinyl acetate-acrylic emulsion, a polyvinyl alcohol aqueous solution, an organic siloxane dispersion liquid, an organic silicon powder waterproof agent, an anti-caking agent and an inorganic filler. According to the invention, the redispersible latex powder with excellent performance is successfully prepared by carefully selecting and adjusting the type and dosage of the organosiloxane and the type of the anti-caking agent and accurately setting the temperature of the drying tower. When the latex powder is applied to the field of constructional engineering, the waterproof performance and durability of mortar can be remarkably enhanced, and wide application potential is shown.
本发明涉及乳胶粉技术领域，公开了一种柔性氯醋丙防水乳胶粉及其制备方法，所述柔性氯醋丙防水乳胶粉由下述组分制成：氯乙烯‑醋酸乙烯‑丙烯酸乳液、聚乙烯醇水溶液、有机硅氧烷分散液、有机硅粉末防水剂、抗结块剂和无机填料。本发明通过精心挑选和调整有机硅氧烷的种类及用量、抗结块剂的种类，并精确设定干燥塔的温度，成功制备出性能优异的可再分散乳胶粉。该乳胶粉在建筑工程领域的应用，能够显著增强砂浆的防水性能与耐久性，展现出广阔的应用潜力。
