背景技术
随着建筑行业的迅猛发展,人们的环保意识和对日常生产生活中的环境的要求也在不断提高,水性涂料以其水性、环保的优点得到所未有的速度发展,逐渐成为室内装饰材料的主打产品。
然而,因水性涂料在制作过程中添加了大量的水、有机合成树脂乳液等有机物质,为细菌等微生物提供了适宜的生长条件和养料,当涂料用于较为阴暗潮湿的环境中时,各类霉菌、细菌就会在水性涂料形成的涂层上附着,形成生物膜,然后聚集成菌落,大量繁殖、破坏涂层结构,导致涂层粉化、脱落,失去保护功能,进而危害被保护材料自身的性能,造成了不必要的损失和浪费。尤其在食品、制药等行业中使用时,这些细菌的大量繁殖还危及产品的安全性能,甚至危及人体健康。
因此,亟需开发一款抗菌性能较佳的涂料,降低其使用时被细菌等微生物侵蚀的可能性,从而维持长期、有效的防护性能。

检测方法
参照GB/T 21866-2008,对实施例1-14和对比例1-2制得的抗菌水性涂料进行抗菌效率测试,抗菌效率越高,表明涂料的抗菌性能越好,具体检测结果如下表3所示:
