Description

一种新型建筑用聚乙烯醇内墙涂料
技术领域
本申请属于涂料领域，尤其涉及一种建筑用聚乙烯醇内墙涂料。
背景技术
中国传统的溶剂型涂料比重逐渐下降，水性涂料的发展速度也很快，但聚乙烯醇类低档品种仍占较大比重。提高水性涂料的质量、开发新的品种是巩固和发展水性涂料的重要环节。重点研究和开发应以醋酸乙烯-丙烯酸共聚乳液、苯乙烯-丙烯酸共聚乳液以及纯丙烯酸系列为基料的乳胶涂料为主，并争取在耐久性、漆膜平滑性、丰满度、施工性、装饰性等方面有所突破；对于已较成熟的环氧乳液、水性聚氨酯的水性基料应继续研究具有高性能的水性涂料，满足部分的特殊要求。内墙涂料就是一般装修用的乳胶漆。乳胶漆即是乳液性涂料，按照基材的不同，分为聚醋酸乙烯乳液和丙烯酸乳液两大类。乳胶漆以水为稀释剂，是一种施工方便、安全、耐水洗、透气性好的的涂料，它可根据不同的配色方案调配出不同的色泽。种类：水性内墙漆、油性内墙漆、干粉型内墙漆，属水性涂料，主要由水，乳液，颜料，填料，添加剂五种成分构成。而随着人性化理念的普及，及新型和谐社会的构成，设计一种不流挂、耐水性及耐热性优异的建筑用聚乙烯醇内墙涂料是非常必要的。
