[发明专利]一种反射隔热外墙建筑涂料及制备方法

摘要

本发明公布了一种反射隔热外墙建筑涂料，属于建筑物的外墙涂料技术领域；反射隔热外墙建筑涂料按重量份计如下：水适量，纤维素0.2～0.3份，pH调节剂0.15～0.2份，分散剂0.5～0.7份，润湿剂0.15～0.4份，消泡剂10.15～0.3份，钛白粉18～25份，填料8～12份，远红外陶瓷粉（1250目）2～3份，空心玻璃微珠（65μm）0～4份，空心玻璃微珠（50μm）0～8份，空心玻璃微珠（40μm）0～6份，丙烯酸酯共聚弹性乳液20～28份，消泡剂20.15～0.3份，防冻剂1.0～2.5份，成膜助剂1.0～1.5份，防腐防霉剂0.2～0.4份，增稠剂1.0～1.5份；本发明反射隔热外墙建筑涂料是采用不同尺寸空心玻璃微珠按照一定比例进行复配既可保证涂层表面光滑，太阳反射率较高，耐沾污性能较好，也可保证涂层中气体体积分数的增加，从而大大提高涂层的隔热保温性能。
