NOVELTY - A photocurable coating comprises 30-50 pts. wt. epoxy acrylate resin, 10-23 pts. wt. silicone oligomer, 5-8 pts. wt. modified photosensitive graphene, 0.5-1 pt. wt. photoinitiator, 5-15 pts. wt. reactive diluent, 3-6 pts. wt. pigment, 4-8 pts. wt. filler, 1-5 pts. wt. other additives and 40-60 pts. wt. solvent. USE - Photocurable coating for coating inner wall of oil and gas storage tank (claimed). ADVANTAGE - The photocurable coating has improved photocuring properties, electrical conductivity, anticorrosive property and static conductivity, and can satisfy requirements of oil and gas storage tank. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of photocurable coating, which involves mixing raw materials, stirring at 200-300 rpm, mixing and further stirring at 300-350 rpm; and (2) usage method of photocurable coating for coating inner wall of oil and gas storage tank, which involves obtaining coating, spraying on inner wall of oil and gas storage tank to a thickness of 2.3-2.5 mm, photo-curing, drying and curing with UV light.
