技术领域
本发明涉及涂料的技术领域，特别涉及弹性涂料的技术领域。
背景技术
弹性涂料是以合成树脂乳液为基料，与颜料、填料及助剂配制而成，施涂一定厚度后，具有弥盖因基材伸缩产生细小裂纹的有弹性的功能性涂料。通常包括溶剂型、乳液型及无机型弹性涂料。其中溶剂型、乳液型弹性涂料延伸率高，成膜效果好，但强度、硬度相对较差，耐候、耐热性差，而无机型弹性涂料成膜效果相对较差，弹性一般较低。
发明内容

一种弹性涂料的制备方法，包括以下步骤：
（1）将气相二氧化硅与第一部分去离子水混合，加入偶联剂，在室温下搅拌10～30min，其后加入煅烧高岭土搅拌均匀；
（2）将由步骤（1）得到的浆料加入纯丙乳液中，其后加入分散剂，润湿剂，成膜助剂，羟甲基纤维素和剩余的去离子水，搅拌均匀，即得到所述弹性涂料；
第一部分去离子水的质量为所述气相二氧化硅的1～2倍。
优选的是：所述偶联剂为硅烷偶联剂。
另外优选的是：所述分散剂为聚乙烯醇。
另外优选的是：所述成膜助剂为丙二醇乙醚。
另外优选的是：所述润湿剂为丙二醇。
另外优选的是：所述组分按质量份计，包括纯丙乳液30～50份，分散剂0.1～1.0份，润湿剂5～10份，偶联剂0.5～1.5份，成膜助剂0.5～2.5份，羟甲基纤维素0.1～0.5份，煅烧高岭土5～15份，气相二氧化硅1～5份，去离子水5～15份。
另外优选的是：所述弹性涂料的组分还包括消泡剂和/或流平剂。
本发明具有以下有益效果：
（1）本发明加工过程简单，能源消耗少，可控性高，得到的产品质量稳定，性质均一；
（2）本发明制得的弹性涂料涂膜具有500%以上的延伸率，能弥盖细微裂缝；（2）本发明制得的产品具有较高的硬度、强度，良好的耐热、耐候、耐老化性。
