NOVELTY - A coating material comprises 80-200 pts. wt. polyethylene terephthalate, 100-220 pts. wt. poly(ethylene 2,6-naphthalenedicarboxylate), 20-30 pts. wt. 1,4-cyclohexanedimethanol polyester, 20-30 pts. wt. silicone oil, 3-8 pts. wt. graphene, 10-20 pts. wt. leveling agent, 3-8 pts. wt. curing agent and 30-80 pts. wt. filler. USE - Coating material for electronic device. ADVANTAGE - The coating material has self-cleaning function, strong corrosion resistance, long-term effective in extreme environments such as moisture, acid and alkali, long service life, long storage time under low temperature conditions, and is not easy to cure when used at room temperature, and saves spraying time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of coating material, which involves (1) adding polyethylene terephthalate, poly(ethylene 2,6-naphthalenedicarboxylate), 1,4-cyclohexanedimethanol polyester and silicone oil, stirring at normal temperature for 4-10 minutes, (2) warming up to 45-60 degrees C, adding graphene, leveling agent and filler, continuously stirring for 4-10 minutes, (3) cooling to 0-4 degrees C, adding curing agent, continuously stirring for 4-10 minutes and storing at low temperature of 0-8 degrees C.
