NOVELTY - Anticorrosive and heat-dissipating graphene coating comprises component A and component B, where the component A comprises 40-50 pts. wt. epoxy resin, 6-10 pts. wt. acrylic resin, 15-20 pts. wt. zinc powder, 0.4-2 pts. wt. graphene, 2-5 pts. wt. dispersant, 0.5-4 pts. wt. coupling agent, 1-3 pts. wt. leveling agent, 6-10 pts. wt. filler, 9-14 pts. wt. synergistic agent and 22-30 pts. wt. solvent. The component B comprises 1-4 pts. wt. curing agent and 3-5 pts. wt. diluent. USE - Anticorrosive and heat-dissipating graphene coating for magnet. ADVANTAGE - The anticorrosive and heat-dissipating graphene coating improve the corrosion resistance of the magnet and the service life of the magnet, and expands its application range, and has good heat dissipation performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing anticorrosive and heat-dissipating graphene coating, which involves: (A) adding 9-12 pts. wt. nano alumina, 7-10 pts. wt. polyvinylidene fluoride resin, 5-7 pts. wt. maleic anhydride grafted ethylene-octene copolymer, 4-7 pts. wt. gamma -glycidoxypropyltrimethoxysilane to 20-30 pts. wt. polyethylene glycol, stirring and mixing uniformly to prepare mixture A; and (B) stirring the mixture A at 80-95 degrees C for 60-90 minutes, ultrasonically dispersing, then centrifuging, washing, and drying to prepare a synergist.
