▎ 摘　　要

NOVELTY - Epoxidized product preparation involves using graphene in the form of graphene solution as modifier, and strong acid as catalyst, and then participating in epoxidation reaction of the unsaturated fatty acid or ester to obtain the modified epoxidized product of the unsaturated fatty acid or ester. The graphene stock solution is a graphene solution which is directly obtained by untreated and graphene during the preparation of graphene by graphite in a redox process. USE - Method for preparing epoxidized product of unsaturated fatty acid or ester modified by graphene liquid used as fiber lubricant, preferably ultra-high molecular weight polyethylene fibers (all claimed). ADVANTAGE - The method prepares the epoxidized product in a simple and cost-effective manner with reduced unsaturated fatty acid epoxidation reaction.
