摘　　要：采用石墨烯与片状锌粉取代醇溶无机富锌涂料中的球状锌粉,以正硅酸乙酯水解液为成膜物质,制备了一种全片层状结构的鳞片型醇溶无机烯锌涂料;采用盐雾、与水接触角、附着力、SEM等测试方法对不同石墨烯含量的鳞片型醇溶无机烯锌涂料的性能进行了评价,并对其耐蚀机理进行了分析。Graphene and flaky zinc powder are used to replace partially spherical zinc powder in alcohol-soluble inorganic zinc-rich coatings. In addition, TEOS hydrolysis is used as film-forming material to prepare the flaky graphene-zinc coatings. The effects of graphene dosage on properties of the prepared graphene-zinc coatings have been investigated via salt fog test, water contact angle test, adhesion test and SEM. Furthermore, the anticorrosive mechanism is also analyzed.
