摘要:
为解决新能源汽车车身金属部件易腐蚀问题，以水性环氧树脂为基料、锌粉为活性防锈颜料，制备富锌水性环氧涂层；通过优化原料配比、改进制备工艺，深入探究不同因素对涂层性能影响；通过电化学工作站、盐雾试验箱、扫描电子显微镜等设备，对镀层的耐蚀性能、微观结构、附着力、硬度等性能进行研究。结果表明，当锌粉质量分数为80%、水性环氧树脂与固化剂质量比为4﹕1、添加0.5%分散剂和0.3%流平剂时，涂层综合性能最佳，在新能源汽车车身防护领域展现出良好应用前景。
Abstract:
In order to solve the problem of easy-corrosive metal parts of new energy vehicle body, waterborne epoxy resin as binder and zinc powder as active anti-rust pigment were used to made zinc-rich waterborne epoxy coatings. By optimizing the ratio of raw materials and improving the preparation process, the influence of different factors on the performance of the coatings were deeply explored. The corrosion resistance, microstructure, adhesion, hardness and other properties of the coating were studied by electrochemical workstation, salt spray test box, scanning electron microscope and other equipments. The results show that, when the mass fraction of zinc powder is 80%, the mass ratio of waterborne epoxy resin to curing agent is 4﹕1, and 0.5% dispersant and 0.3% leveling agent are added, the coating has the best comprehensive performance and shows a better application prospect in the field of new energy vehicle body protection
