摘　　要：针对传统夯土墙用的溶剂型变色涂料存在大量易挥发有机物,从而给装饰带来污染的问题,制备一种以水性丙烯酸为基液,以致热变色微胶囊为变色材料,以轻质碳酸钙、增稠剂、流平剂为助剂的新型装饰变色合成涂料。通过试验,确定了制备合成涂料的最佳配比。在性能方面,该涂料的变色温度和复色温度区间分别在37.8~40.2℃、37.3~32.4℃;涂料变色和复色时间分别为45.5s、59.4s,表现出良好的可逆性。其他基本性能皆符合国家对室内装饰涂料的使用要求。In order to solve the problem of environmental pollution caused by volatile organic compounds in the production and application of traditional solvent based color change coatings,a decorative color change coating with water-based acrylic acid as base solution,thermochromic microcapsule as color changing material,light calcium carbonate,thickener and leveling agent as auxiliary agents is proposed.The optimum proportion of the paint was determined by studying the composition which affected its performance.The color changing,hecoloring temperature range of the coating were 37.8~40.2℃,37.3~32.4℃,respectively The color changing and re coloring time of the coating were 45.5 s and 59.4 s,respectively.Other basic properties are in line with the national requirements for interior decoration coatings.
