一种自修复石墨烯富锌防腐涂料及其制备方法
摘要：
本发明公开一种自修复石墨烯富锌防腐涂料，由以下重量份的原料组成：石墨烯悬浮液25‑40份、环氧树脂9‑11份、锌粉45‑50份、填料4‑6份、助剂8‑10份、固化剂15‑20份，其中，所述石墨烯悬浮液是通过以下方法制备得到的：（1）使用硅烷偶联剂对氧化石墨烯进行改性，得到改性氧化石墨烯；（2）石墨烯悬浮液的制备：按照料液比1g:400mL，将改性氧化石墨烯加入到二甲苯中，超声分散，自然冷却至室温，加入抗坏血酸，在40‑60℃下搅拌4‑7h。本发明提供的自修复石墨烯富锌防腐涂料，力学性能良好，防腐性能优异，能降低锌粉含量，在涂层出现裂缝时能自我修复。
摘要（英）：

The invention discloses self-repairing graphene zinc-rich anticorrosive paint. The self-repairing graphene zinc-rich anticorrosive paint is prepared from, by weight, 25-40 parts of a graphene suspension liquid, 9-11 parts of epoxy resin, 45-50 parts of zinc powder, 4-6 parts of a filler, 8-10 parts of an assistant and 15-20 parts of a curing agent, wherein the graphene suspension liquid is prepared through the following steps that (1) a silane coupling agent is utilized to modify graphene oxide to obtain modified graphene oxide; (2) the graphene suspension liquid is prepared, wherein accordingto a solid-liquid ratio of 1 g:400 mL, the modified graphene oxide is added into xylene, ultrasonic dispersion is carried out, natural cooling is carried out to the room temperature, ascorbic acid isadded, and stirring is carried out for 4-7 h at 40-60 DEG C. The self-repairing graphene zinc-rich anticorrosive paint has the advantages that the mechanical property is good, the antiseptic propertyis excellent, the content of the zinc powder can be reduced, and the anticorrosive paint can perform self-repairing when cracks appear in a coating.
