▎ 摘　　要

NOVELTY - A graphene high-heat-dissipation anticorrosive coating comprises 40-50 parts mass epoxy resin, 5-8 parts mass modified thermally-conductive graphene material, 22-30 parts mass thermally-conductive filler, 10-18 parts mass anticorrosive filler, 3-5 parts mass additive, 6-10 parts mass solvent, and 16-20 parts mass epoxy curing agent. USE - Graphene high-heat-dissipation anticorrosive coating is used for charging pile. ADVANTAGE - The graphene coating has high heat dissipation performance (thermal conductivity 18 W/mK or more) and excellent anticorrosive performance. The modified thermally-conductive graphene material and epoxy resin are used to form a spatial network thermally-conductive polymer structure to improve thermal conductivity of film-forming substrate and increase heat dissipation area of the graphene coating. Graphene covalent bond is introduced into the thermally-conductive polymer to improve dispersion of graphene, increase thermal conduction transmission channel, improve interaction between the resin and thermally-conductive filler and give full play to the thermal conduction effect of the thermally-conductive filler. The heat inside the charging pile can be exported in time to ensure working efficiency and operating life of the charging pile at high temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene high-heat-dissipation anticorrosive coating, which involves adding (i) epoxy resin to a dispersion tank, adding additive and dispersing at a high speed of 600 rpm for 0.5 hour to obtain a resin solution system, adding (ii) modified thermally-conductive graphene material, thermally-conductive filler and anticorrosive filler to the resin solution system in batches and dispersing at a high speed of 1000 rpm for 1 hour to obtain a viscous liquid mixture, adding (iii) solvent to the viscous liquid mixture in batches to adjust the viscosity of the mixture and dispersing at a high speed of 1500 rpm for 1 hour to obtain a pre-dispersed coating, continuously dispersing (iv) the pre-dispersed coating at a speed of 1800 rpm until the coating fineness is 60 mu m or less, and mixing (v) the epoxy curing agent with the mixture obtained in the process (iv).
