Description

耐候性外墙防水涂料
技术领域
本发明涉及涂料生产领域，具体涉及一种耐候性外墙防水涂料。
背景技术
外墙涂料主要是用于粉刷建筑外部的涂料，其功能是抗紫外线、防水，达到保护建筑物的目的。现有技术，涂料在应用中通常存在以下问题：涂料的防水性能不好，将其涂覆在建筑物外墙后，长时间的风吹雨淋，外层的涂料会出现脱落、开裂现象，这就影响了建筑物的外观和防水性能；耐候性不好：外墙涂料涂层暴露于大气中，要经受风吹、日晒、盐雾腐蚀、雨淋、冷热变化等作用，在这些外界自然环境的长期反复作用下，涂层易发生开裂、粉化、剥落、变色等现象，使涂层失去原有的装饰保护功能；装饰性差：外墙涂料保色性差，不能长时间保持外墙原有的装饰性。
发明内容
本发明的目的在于提供一种具有弹性、防化学腐蚀的耐候性外墙防水涂料。
本发明的一种耐候性外墙防水涂料，该涂料由以下重量份的组分组成：苯丙乳液100份、苯乙烯乳液35-40份、丙烯酸乳液7-9份、羟乙基纤维素6-10份、分散剂5-8份、消泡剂0.8-1.6份、乙二醇12-16份、防腐剂0.5-1.5份、润湿剂1-2份、钛白粉40-50份、轻质碳酸钙35-45份、滑石粉20-24份、高岭土33-35份、流平剂0.3-0.7份，水70-76份。
优先该涂料由以下重量份的组分组成：苯丙乳液100份、苯乙烯乳液37.5份、丙烯酸乳液8份、羟乙基纤维素8份、分散剂6.5份、消泡剂1.2份、乙二醇14份、防腐剂1份、润湿剂1.5份、钛白粉45份、轻质碳酸钙40份、滑石粉22份、高岭土34份、流平剂0.5份，水73份。
所述的润湿剂为聚乙二醇烷基芳基醚。
所述的流平剂为1,2丙二醇。
本发明具有以下特点和优点：
1、本发明外墙涂料具有优异的耐候性、防水性、耐化学腐蚀、耐霉变性；
2、本发明涂料能较长时间保持外墙原有的装饰性能；
3、本发明涂料形成的外墙涂层具有较好的弹性延伸率，具有超长的户外耐久性。
