本发明公开了一种含腰果酚基活性稀释剂改性氧化石墨烯填料的复合涂料及其制备方法与应用,该涂料由组分Ι与组分П组成,所述的Ι组分包括:腰果酚基活性稀释剂改性氧化石墨烯纳米片0 .1~1 .0份;石油基环氧树脂50~80份;腰果酚基活性稀释剂20~50份;所述的П组分包括:腰果酚基固化剂40~50份;消泡剂0 .01~0 .2份;流平剂0 .03~0 .3份;防沉剂0 .05~0 .2份。本发明通过简单的共价功能化法设计并合成了腰果酚基活性稀释剂改性氧化石墨烯纳米片(A‑GO),改善了GO在环氧树脂基体中的分散性与相容性,能有效弥补环氧树脂涂层内部存在的缺陷。将A‑GO添加到腰果酚基活性稀释剂中,并与腰果酚基活性稀释剂协同作用,最终得到A‑GO/腰果酚基稀释剂/环氧树脂复合涂料。
The present invention discloses a composite coating with cashew phenolic based active diluent modified graphene oxide filler and its preparation method and application. The coating comprises Ι And components П Composition Ι The components include: 0.1 to 1.0 parts of cashew phenolic based active diluent modified graphene oxide nanosheets; 50-80 parts of petroleum based epoxy resin; 20-50 parts of cashew phenolic active diluent; in question П The components include: 40-50 parts of cashew phenolic curing agent; 0.01-0.2 parts of defoamer; 0.03-0.3 parts of leveling agent; 0.05-0.2 parts of anti settling agent. The present invention designs and synthesizes cashew phenolic based active diluent modified graphene oxide nanosheets (A-GO) through a simple covalent functionalization method, improving the dispersion and compatibility of GO in the epoxy resin matrix, and effectively compensating for the internal defects of the epoxy resin coating. Add A-GO to cashew phenolic active diluent and mix with the synergistic effect of cashew phenolic based active diluent ultimately resulted in the preparation of A-GO/cashew phenolic based diluent/epoxy resin composite coating.
