摘　　要：本研究以环氧树脂和聚酰胺固化剂为主体,研制了一系列环氧富锌底漆,并且对树脂比例、锌粉含量及形状、有机-无机杂化剂的含量和固化剂体系等影响因素进行分析和优化。结果表明,当环氧树脂E51和75%E20的质量比为4∶1、锌粉质量分数为80%、球状锌粉与鳞片状锌粉质量比为3∶1、有机-无机杂化剂质量分数为1.8%、固化剂BS890-70X与BS853N的质量比为1∶1时,所制备的环氧富锌底漆具有快干、良好的附着力和耐盐雾性能。与市售的环氧富锌底漆相比,研制的富锌底漆在中性盐雾环境下,具有更好的表观性、耐老化性和耐腐蚀性,可广泛应用于石油石化行业中的油罐和炼化企业的钢结构防腐工程。In this study,with the epoxy resin and polyamide curing agent as the main body,a series of zinc-rich epoxy primers was prepared.The influence factors such as resin ratio,zinc powder content and shape,organicinorganic hybrid agent content and curing agent system were analyzed and optimized.The result showed that when the mass ratio of epoxy resin E51 to 75%E20 is 4∶1,the mass fraction of zinc powder is 80%,the mass ratio of spherical zinc powder to flake zinc powder is 3∶1,the mass fraction of organic-inorganic hybrid agent is 1.8%,and the mass ratio of curing agent BS890-70X to BS853N is 1∶1,the prepared epoxy zinc-rich primer has fast drying speed,good adhesion and salt spray resistance.Compared with the commercially available epoxy zinc-rich primer,the developed epoxy zinc-rich primer has better appearance,aging resistance and corrosion resistance in the neutral salt spray environment.It can be widely used in anti-corrosion engineering of steel structure of oil tank and refining enterprise in petroleum and petrochemical industry.
