Preparation method of anti-cracking water-based damping coating

The invention discloses a preparation method of an anti-cracking water-based damping coating, wherein the preparation method comprises the following steps: step a, adding a core-shell emulsion, a wetting dispersant, a defoaming agent, a coalescing agent, a water-soluble cosolvent and water into a stirrer to obtain a mixture A; step b, sequentially adding polypropylene fibers, a flame retardant and an inorganic filler into the obtained mixture A to obtain a mixture B; step c, adding a silane coupling agent into the obtained mixture B to obtain a mixture C; and step d, adding a thickening agent into the obtained mixture C to obtain the anti-cracking water-based damping coating. 本发明公开了一种抗开裂水性阻尼涂料的制备方法，包括以下步骤：步骤a：向搅拌器内加入核壳型乳液、润湿分散剂、消泡剂、成膜助剂、水溶性助溶剂和水，得到混合料A；步骤b：向得到的混合料A中依次加入聚丙烯纤维、阻燃剂和无机填料，得到混合料B；步骤c：向得到的混合料B中加入硅烷偶联剂，得到混合料C；步骤d：向得到的混合料C中加入增稠剂，得到抗开裂水性阻尼涂料。
