摘　　要：采用水热法制备的纳米TiO2作为增强材料对环氧树脂进行改性,分散纳米TiO2到正在生成的环氧树脂中,制备纳米TiO2/环氧树脂涂层,研究了纳米TiO2含量对涂层硬度、附着力、冲击性能、耐腐蚀性和光催化性能的影响.结果表明,随着纳米TiO2的适量加入,环氧树脂涂层的各项性能均不同程度改善,当纳米TiO2的加入量为0.05%时,涂层硬度、附着力、耐冲击性能、耐腐蚀性和光催化性能均达到最佳值.The nano-TiO2 prepared by hydrothermal method is used as reinforcing material to modify epoxy resin.And the nano-TiO2/epoxy resin coatings are prepared by dispersing nano-TiO2 into the forming epoxy resin.The effect of nano-TiO2 content on the hardness,adhesion,impact properties,corrosion resistance and photocatalytic performance of the coatings is studied.The results show that the properties of epoxy coating has improved in varying degrees with the addition of nano-TiO2.When the amount of nano-TiO2 is 0.05%,the hardness,adhesion,impact resistance,corrosion resistance and photocatalytic performance of the coating achieves the optimum value.
