Description
本发明涉及一种绝缘涂料、制备方法和应用，具体涉及一种水性环保绝缘涂料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。
现在钢铁上一直应用传统的油漆沥青漆产品，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。水性漆在钢板上的应用容易脱落，附着力达不到、防腐性能达不到等弊病。
有鉴于此，本发明提供了一种水性环保绝缘涂料及其制备方法和应用，具体采用如下技术方案：

进一步，稀土盐混合溶剂为两种或两种以上的稀土元素的盐，搅拌得到稀土盐溶液。
进一步，防沉剂为5020W；
增稠剂为738C；
偶联剂为B551。
本发明还提供了上述水性环保绝缘涂料的制备方法，包括以下步骤：
1）按上述重量份数称取原料；
2）将氧化镁与磷酸反应，搅拌至氧化镁充分溶解；
3）将磷酸二氢铝溶液与硅溶胶溶液混合；
4）搅拌好的两种液体自然混合，冷却后依次加入防沉剂、增稠剂、偶联剂，搅拌均匀即得水性环保绝缘涂料。
进一步，步骤2）中所述搅拌的转速为1000-1200转/分钟。
进一步，步骤4）还包括在加入防沉剂、增稠剂、偶联剂的同时进行搅拌的操作。
本发明还提供了上述水性环保绝缘涂料在钢板上的应用。
本发明的有益效果在于，本发明以水作溶剂，节省大量资源，不含苯、二甲苯、乙烷、甲醛等VOC有害物质，不经过任何研磨程序，直接搅拌即可，制备方法简单可靠，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。本发明在钢板表面附着力强，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。
