| 目的 研究钛纳米填料粒径和含量对环氧基钛纳米复合导静电涂层耐蚀性能的影响。 方法将不同粒径的钛纳米粉(经聚乙烯基吡咯烷酮表面预处理)按不同量加入双酚 A(E)型环氧树脂中,之后涂覆在 Q235 钢表面形成导静电复合涂层。 通过表面电阻测试、截面形貌观察、电化学极化曲线和阻抗谱测试,分别评价复合涂层的导静电性能、截面结构和耐蚀性。 结果 钛纳米粉添加量(占涂层质量百分比)为 28% 时,随着钛纳米粉粒径从 40 nm 增大到 200 nm,环氧基复合导静电涂层的表面电阻降低,截面结构更加杂乱,添加 100 nm 钛纳米粉的涂层阻抗和极化曲线阳极电流分别出现最大值和最小值。 添加的钛纳米粉粒径为 100 nm 时,随着添加量从 7% 增至 28% ,环氧基复合导静电涂层的表面电阻降低,截面孔洞增大,阻抗值降低,极化曲线阳极电流增大。 结论 钛纳米填料的加入可以有效提高涂层的导静电性能、致密性和耐蚀性。 当添加量为 28% 时,钛纳米粒径大于 100 nm 后,涂层截面形貌更加杂乱,耐 |

| Objective To figure out the effect of Ti particle size and content on the corrosion resistance of epoxy antistatic composite coatings. Methods In this paper, different addition amounts of PVP pre-treated Ti particles with different particle size were introduced into Bisphenol A(E) type epoxy resin, and the resultant composite coatings were prepared on Q235 sheets. Surface resistance test, section morphology observation, electrochemical polarization curves and impedance spectroscopy tests were conducted to investigate the antistatic properties, internal structure and corrosion resistance of the composite coating. Results The surface resistance of composite coatings with 28% Ti content (wt% in coating) decreased, and the section structure was more complex as the particle size increased from 40 nm to 200 nm. The coating with the maximum electrochemical resistance and minimum anodic current density was obtained when the Ti particle size was 100 nm. For composite coatings with 100 nm Ti particles, as Ti content increased from 7% to 28% , the coating surface resistance and electrochemical resistance decreased, while the coating section porosity and electrochemical anodic current density increased. Conclusion The addition of Ti nano-particles could effectively improve the antistatic property, densification and corrosion resistance of coatings. But when the Ti particle size was larger than 100 nm, the coatings with 28% Ti content had more complex section structure and decreased corrosion resistance. For composite coatings with 100 nm Ti particles, the densification and corrosion resistance decreased when the Ti content was more than 7% . |
