Description
技术领域
本发明主要涉及涂料领域，尤其涉及一种可替代喷砂的锅具用防磨涂料及其制备方法。
背景技术
喷砂是利用高速砂流的冲击作用清理和粗化基体表面的过程。采用压缩空气为动力，以形成高速喷射束将喷料(铜矿砂、石英砂、金刚砂、铁砂、海南砂)高速喷射到需要处理的工件表面，使工件表面的外表面的外表或形状发生变化，由于磨料对工件表面的冲击和切削作用，使工件的表面获得一定的清洁度和不同的粗糙度，使工件表面的机械性能得到改善，因此提高了工件的抗疲劳性，增加了它和涂层之间的附着力，延长了涂膜的耐久性，也有利于涂料的流平和装饰，但是喷砂工艺复杂，对设备和成本要求较高，因此为了节约生产成本，本发明设计一种可替代传统喷砂工艺的涂料。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种可替代喷砂的锅具用防磨涂料及其制备方法。
本发明是通过以下技术方案实现的：
一种可替代喷砂的锅具用防磨涂料，它是由下述重量份的原料组成的：

一种可替代喷砂的锅具用防磨涂料的制备方法，包括以下步骤：
(1)将上述磷酸二氢铝加入到其重量10-13倍去离子水中，在70-80℃下保温搅拌3-5分钟，加入聚乙烯醇，搅拌均匀，为铝溶胶；
(2)将上述八水氧氯化锆加入到其重量10-12倍的去离子水中，搅拌均匀，加入上述27.5％双氧水，搅拌反应30-40分钟，滴加浓度为20-25％的氨水，调节pH为4-6，升高温度为60-70℃，保温反应1-2小时，加入上述氯化镧、维生素c，搅拌至常温，得稀土锆溶胶；
(3)将上述纳米二氧化硅加入到其重量100-120倍的去离子水中，加入硼砂、环烷酸锂，加热至60-65℃，超声2-3分钟，得硅分散液；
