Description
本发明涉及一种水性漆、制备方法及其应用，具体涉及一种水性氟碳漆及其制备方法和应用，属于涂料领域。
进入21世纪以来环境保护越来越受到世人的关注，在涂料工业领域，溶剂型涂料含有大量的挥发性有机溶剂(VOC)，在使用过程中排入大气，不仅破坏大气环境，危害人们健康，同时也浪费资源，浪费能源。目前，一般将水性涂料、粉末涂料、高固分涂料以及辐射固化涂料称为环保涂料。
以水溶性树脂或水分散性树脂，包括合成聚合物乳液为基料的涂料均称为水性涂料。因此水性涂料也常称为水基涂料。合成聚合物乳液为基料的涂料均称为水性涂料。
氟碳漆以其特有的耐候性、抗玷污、耐溶剂、耐酸碱、疏水等特性受到装饰界的关注和青睐。
目前的氟碳漆主要是以溶剂型为主，而由于溶剂型氟碳漆含有较高的VOC，施工时溶剂直接挥发在空气中无法回收，造成资源浪费，污染环境，对施工人员也有一定的毒害，实施工具难以清洗干净。此外，溶剂型氟碳漆的漆膜致密，透气性差，容易形成局部起泡。而另一方面，现有技术中的乳胶漆的耐候性、抗玷污性和耐老化性又不能满足使用的需要。
现在ABS表面一直应用传统的油漆产品，主要成分为二甲苯、沥青、丁醇、石油树脂等，属于易燃易爆品，VOC严重超标，环保形势下属于禁用产品，现在大力倡导环保安全，全部改换成环保水性漆产品是必然趋势。
有鉴于此，本发明提供了一种水性氟碳漆及其制备方法和应用，具体采用如下技术方案：

进一步，水性氟碳树脂为丙烯酸全氟烷基乙基酯共聚物、甲基丙烯酸全氟乙基酯共聚物、全氟丙烯共聚物或偏二氟共聚物中的一种或几种的混合物。
进一步，色浆为无机色浆。
进一步，消泡剂为SN-6710；流平剂为SN-4034；润湿剂PDF-4727；分散剂SN-1727；附着力促进剂SN-7520。
本发明还提供了上述水性氟碳漆的制备方法，包括以下步骤：
1）按上述重量份数称取原料；
2）将水性氟碳树脂与水性超支化基材封闭树脂混合搅拌；
3）在搅拌好的混合物中加入色浆，继续搅拌；
4）向搅拌好的液体中依次加入消泡剂、流平剂、润湿剂、分散剂、附着力促进剂，混合均匀即得水性氟碳漆。
进一步，步骤2）中搅拌的转速为1000-1200转/分钟，搅拌时间为20-30分钟。
进一步，步骤3）中继续搅拌的转速为200-300转/分钟，搅拌时间为5-10分钟。
进一步，步骤4）还包括在加入消泡剂、流平剂、润湿剂、分散剂、附着力促进剂的同时进行搅拌的操作。
本发明还提供了上述水性氟碳漆在ABS材料上的应用。
本发明的有益效果在于，本发明以水作溶剂，无味，节省大量资源，不含苯、二甲苯、乙烷、甲醛等有害物质，防腐性能优良，复涂性能良好，抗辐射，不燃不爆消除了施工、储存时火灾隐患，降低了对大气污染，在密闭环境中也可照常施工，不经过任何研磨程序，直接搅拌即可，制备方法简单可靠，在ABS材料表面附着力强，耐候性强，操作性能简单，涂装工具可用水直接清洗，大大有效减少对施工人员的伤害。
