水性丙烯酸涂料制备及其固化性能研究

摘要：以甲基丙烯酸甲酯、丙烯酸丁酯为主要单体, 以过氧化苯甲酰为引发剂,通过引入亲水性基团羧基和羟基,制备了水性丙烯酸树脂。得到水性丙烯酸涂料后用其在木制品上面漆进行主要成膜物质的化学成分分析和漆膜性能测试，研究水性丙烯酸涂料中成膜物质对涂料综合性能的影响，揭示影响因素与机理，以期为水性丙烯酸涂料的研发改良及应用奠定基础。

Abstract: Using methylmethacrylate, butylacrylate as main monomer and benzoylperoxide as initiator, the aqueous acrylic resin was prepared by introducing a group of carboxyl and hydroxyl groups. After obtaining waterborne acrylic coating, the chemical composition analysis and film performance test of the main film-forming material were carried out on the wood products. The effects of film forming materials on the comprehensive properties of coatings were studied, and the influencing factors and mechanism were revealed in order to lay a foundation for the development, improvement and application of waterborne acrylic coatings.

Keywords: acrylic resin; waterborne; paint; film Properties

1.引言

随着人们生活水平的提高，安全健康意识逐渐增强。在与人们生活息息相关的家居木制品领域，水性木器涂料^【1】越来越受到政府和消费者的重视 ，这使得家具行业的相关企业不得不开始进行大规模的油改水技术改进。虽然目前传统的溶剂性涂料在国内市场仍占有较大的份额，但水性涂料已经成为未来的主要发展方向。水性丙烯酸树脂^【2】是一种优良的水性涂料用树脂, 它具有防腐蚀, 耐光、耐候性优, 成膜性好, 保色性优, 容易配成施工性良好的胶粘剂和涂料, 使用安全等^【3】优点, 而且对环境无污染^【4】, 符合环保要求。该类聚合物已成为胶粘剂和涂料行业的研究热点之一。
