| 摘 要： | 本文合成了丙烯酸树脂,并选择合适的助剂、溶剂、填料,配制了丙烯酸树脂涂料.为提高涂层的硬度,抗冲击能力,耐磨性等机械性能,加入纳米二氧化硅.采用有机硅烷偶联剂KH-570对纳米二氧化硅进行了改性,解决了纳米粒子的团聚问题,提高了其在涂料中的分散性,制备成二氧化硅-丙烯酸树脂复合涂料.在此基础上使用环氧树脂对涂料进行改性,提高了涂料的交联度,降低了涂料的亲水性.采取合适的固化剂以及涂布工艺,制备成纳米涂层.使用动态光散射、透射电镜、红外光谱等方法对材料进行了表征,并按国家涂料性能检测标准对涂料进行了测试.研究结果表明,采用改性后的二氧化硅制备的涂料涂布的钢板表面细腻平整,具有较好的光洁度.加入适量环氧树脂、固化剂、防锈剂后的涂料涂布后各项机械性能良好,耐碱能力在5%氢氧化钠,25℃的情况下达到了6h以上,耐侯性通过了350h的盐雾测试,耐温水性在80℃下达到了10h以上,耐酸性在5%硫酸,25℃的情况下达到了24h.

| Abstract: | An acrylic resin based nano-complex coating was prepared by mixing silica nanoparticles,acrylic resin and additives.To improve the stability and dispersity of silica in the coating,silane coupling agent(KH-570)was chosen to modify the surface of them.Different amount of epoxy resin were added into this coating to enhance the cross-linking degree and reduce the hydrophilicity of the coating.The chemical proeprties of this coating were analized by several techniques,such as Dynamic light scattering(DLS),Trans... |
