在采用溶胶-凝胶法合成有机-无机杂化丙烯酸树脂的基础上,研究了纳米TiO2添加量对有机-无机杂化丙烯酸复合涂层机械和耐腐蚀等性能的影响。研究表明,当纳米TiO2添加量为15%时,涂层的性能有了较大的提高,其硬度由3H提高至6H,涂层的耐盐雾时间由100h提高到500h,涂层的阻抗值也由104Ω.cm2提高至106Ω.cm2。另外,通过扫描电镜观察了复合涂层的断面,发现涂层中纳米粒子分散均匀,并且粘接紧密,形成了较为致密的复合涂层。

The organic-inorganic hybridization acrylic resin was synthesized with sol-gel method,and the effects of the addition of nano-TiO2 on mechanical properties and corrosion resistance properties of organic-inorganic hybridization acrylic composite coatings have been investigated in detail.The result showed that,when adding 15wt% nano-TiO2,the hardness of coating was improved from 3 to 6H,the salt spray resistance time increased from 100 to 500h,and the resistance got to 106Ω·cm2.Moreover,it can be observed clearly that nano particles dispersed uniformly and densely in the coatings by SEM.The coordination of organic-inorganic hybridization acrylic resin and nano-TiO2 was a good potential method for improving the mechanical properties and corrosion resistance properties of coatings.
