The present invention relates to the preparation and application technology of coatings, specifically concerning an abrasion-resistant, durable superhydrophobic coating for windshield wipers and its preparation method, comprising the following steps: S1. Preparation of preform powder: Mixing epoxy resin powder, curing agent, and abrasion-resistant additives, then feeding the mixture into a twin-screw extruder for extrusion, cooling, and grinding to obtain the preform powder; S2. Preparation of composite particles: Slowly add modified fluorinated graphene dispersed in a solution of ethyl orthosilicate while stirring. Add perfluorooctyl triethoxysilane and continue stirring to obtain a mixed solution. Dry the mixed solution to obtain the composite particles; S3. Mix the pre-made powder with the composite particles, then spray onto a substrate to form a coating. After drying, the superhydrophobic coating is obtained. This hydrophobic coating exhibits excellent wear resistance and superhydrophobic properties, effectively enhancing the coating's superhydrophobic durability. When used on windshield wipers, it resists aging and offers extended service life.
