Abstract:In order to produce a more environment-friendly thermochromic coating, epoxy acrylic acid was used as the film forming material to study the properties of epoxy acrylic acid, and the best proportion was chosen to form epoxy acrylic emulsion. Inorganic thermochromic materials were dispersed in epoxy acrylic resin to prepare epoxy acrylic thermochromic coating. A series of experiments were carried out on the properties of the coatings. The experimental results show that the color of the thermochromic coating made of new epoxy acrylic acid changes obviously when heated, and shows good color changes in engineering applications. It has the advantages of excellent performance, high stability, long-term storage, etc., and can be widely used in chemical anti-counterfeiting, automobile and other industrial fields.
Key words:epoxy acrylic resin; thermochromic coating; thermochromic material
热变色材料一直都是国内外专家研究的重点,但受到材料、技术等影响,初期研究出来的热变色材料都是不可逆的,使得热变色材料的应用受到了很大的局限。随着研究的深入,科学家们也研究制造出低温可逆的变色涂料,扩大了使用范围。但现在多数变色涂料使用的材料都是溶剂型树脂,生产和使用过程中都会产生比较大的污染。为了改善这样的情况,本文特提出新型的环氧丙烯酸变色涂料制备及应用研究方案,将水溶性环氧-丙烯酸树脂作为主要成膜物质,将无机热变色材料融入其中,不仅提高了涂料的性能,也大程度的减小了污染,由此制备出高性能的环保型环氧-丙烯酸热变色涂料。
