Description
本发明涉及一种涂料、制备方法和应用，具体涉及一种水性丙烯酸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。
现在钛镁合金上一直应用传统的油漆产品，主要成分为二甲苯、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。水性漆在钛镁合金上的应用容易脱落，附着力达不到、防腐性能达不到等弊病。
