二次喷涂改性无机涂层
Keywords: 有机改性,无机涂层,kh-550,铝合金
Abstract:
？首先提出一种相对简单的方法对无机涂层材料进行改性，即在处理的铝合金表面制备水性无机涂层，然后在无机涂层表面二次喷涂kh-550改性溶胶，对其进行改性，再经烘烤制备了有机改性无机涂层。对二次喷涂kh-550改性溶胶的一些因素对涂层表面性能影响的研究表明kh-550用量≥20%，能明显提高无机涂层的附着力、耐冲击性、耐水性等理化性能。对二次喷涂后涂层的微观形貌和接触角测试结果表明，在kh-550改性溶胶中引入无机纳米或超细粉体，获得了致密、平整的多功能涂层。最后通过对所提出方法的原理探讨及实验结果的分析，确定二次喷涂kh-550溶胶改性无机涂层材料，制备有机改性无机涂层的方法可行。
