中文摘要:
      环氧树脂以其优异的性能而被广泛应用于工业生产的各个领域,但是随着各国纷纷限制甚至禁止挥发性有机物(VOC)的排放,发展水性环氧树脂成为大势所趋。水性环氧树脂最大的优点是VOC排放量低甚至为零,并且其耐腐蚀、耐盐雾、机械强度、电气绝缘等性能也非常出色,这对于水性环氧树脂在更严苛环境下的应用有着重要意义。系统地介绍了防腐环氧树脂水性化的主要方法。机械法制备工艺简单、成本低廉,是环氧树脂水性化较为普遍的一种方法;化学改性法可以获得均一、稳定的纳米级别的水性环氧树脂乳液;相反转法是一种获得具有高分子量水性环氧树脂乳液的有效方法;固化剂乳化法能够利用固化剂直接与环氧树脂发生反应制备水性环氧涂层。阐述了水性环氧树脂涂层的制备过程,并分析了实验条件对涂层防腐性能的影响规律,重点讨论了其研究现状和影响涂层性能的因素。通过对当前水性环氧树脂制备方法的总结和分析,展望了其今后的发展趋势。
英文摘要:
      Epoxy resins are widely used in various fields of industrial production due to excellent performance, However, as various countries limit or even prohibit emission of volatile organic compounds (VOC) one by one, developing waterborne epoxy resin represents the general trend. The top advantage of waterborne epoxy resin is low or even zero VOC emission, in addition to excellent corrosion resistance, salt spray resistance, mechanical strength and electrical insulation, these advantages are of great significance to application of waterborne epoxy resin in even more stringent environment. Main preparation methods of waterborne anticorrosive epoxy resin were introduced in detail. Mechanical method is a common method of preparing waterborne epoxy resin due to simple preparation process and low cost. Chemical modification method can be used to obtain uniform and stable nano-level waterborne epoxy resin emulsion. Phase inversion method is an effective method of obtaining an aqueous epoxy resin emulsion with high molecular weight. Curing agent emulsifying method can be used to prepare waterborne epoxy coating by making the curing agent directly react with the epoxy resin. Preparation process of waterborne epoxy resin coating was expounded, and rule of effect of experimental conditions on corrosion resistance of the coating was analyzed. Moreover, research progress and influencing factors of coating properties were discussed emphatically. Future development trend was prospected by summarizing and analyzing current preparation methods of waterborne epoxy resin.
