一种自润滑涂料及其制备方法
摘要：
一种自润滑涂料，按照质量百分比含量包括以下组分：40%–55%的水性树脂、25%–46%的助剂、9%–25%的石墨源，石墨源包括石墨烯、氟化石墨，石墨烯在涂料中的质量百分比含量大于6%，该自润滑涂料的制备方法包括：先将石墨烯、氟化石墨分别按照质量百分比含量加入到搅拌机中搅拌后得到复合粉料，再向复合粉料中按照质量百分比含量加入助剂搅拌后得到涂料预制体，最后对涂料预制体依次进行球磨、抽真空处理后得到自润滑涂料。该涂料中石墨烯和氟化石墨发生协同作用，使涂料具有较高的自润滑性能、防腐性能，该制备方法中特定的加料顺序和工艺保证了石墨烯、氟化石墨在涂料中均匀的分散，减少了石墨烯、氟化石墨的用量的同时，降低了生产成本。
摘要（英）：

The invention relates to a self-lubricating coating which comprises the following components in percentage by mass: 40%-55% of aqueous resin, 25%-46% of an auxiliary agent and 9%-25% of a graphite source, the graphite source comprises graphene and fluorinated graphite, and the mass percentage content of the graphene in the coating is more than 6%. The preparation method of the self-lubricating coating comprises the following steps: respectively adding the graphene and the fluorinated graphite into a stirrer according to the mass percentage content to stir to obtain composite powder; adding theauxiliary agent into the composite powder according to the mass percentage content and stirring to obtain a coating preform, and finally carrying out ball milling and vacuumizing treatment on the coating preform in sequence to obtain the self-lubricating coating. The graphene and the graphite fluoride in the coating have synergistic effect, so that the coating has higher self-lubricating performance and corrosion resistance; and the specific feeding sequence and process in the preparation method ensure that the graphene and the fluorinated graphite are uniformly dispersed in the coating, reduce the consumption of the graphene and the the fluorinated graphite, and simultaneously reduce the production cost.
