USE - Graphene-reinforced epoxy ceramic coating. ADVANTAGE - The graphene-reinforced epoxy ceramic coating is dense, smooth, and as firm as ceramics, and has excellent bonding property, water resistance, corrosion resistance and electrical insulation performance, and provides coating with uniform thickness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene-reinforced epoxy ceramic coating, which involves adding silicon carbide powder, dolomite, corn starch, and polyethylene glycol siloxane to a ball mill, mixing, adding alumina and deionized water corresponding to 2-3 times of weight of the silicon carbide powder, ball milling for 8-10 hours, obtaining slurry, stirring the slurry for 20-30 minutes using a magnetic stirrer, injecting into plastic mold, molding at 70-75 degrees C for 30-40 minutes, demolding, continuing drying at 50-60 degrees C for 10-12 hours, in a box-type resistance furnace under air atmosphere, heating to 300 degrees C at a rate of 4-6 degrees C/minute, heat preserving for 50-60 minutes, heating at 1300 degrees C, 1400 degrees C, 1500 degrees C, and 1600 degrees C respectively at 15-20 degrees C/minute for 20-30 minutes, cooling naturally to below 40 degrees C, crushing to 60-80 mesh powder, dispersing graphene oxide in 5-6 times by weight of deionized water, ultrasonically processing for 2-3 hours, adding solution of aniline and hydrochloric acid, stirring the mixture for 4-5 hours in an ice water bath, adding ammonium persulfate solution in drops while magnetically stirring the reaction mixture for 20-24 hours in an ice water bath, leaving still for 10-12 hours, adding sodium hexametaphosphate, tributyl phosphate, and propylene glycol butyl ether, stirring at 800-1000 rpm, adding obtained 60-80 mesh powder, titanium dioxide, magnesium oxide, and barium sulfate, stirring at 1500-1800 rpm for 40-50 minutes, adding alcoholamine diphosphoryloxyglycolic acid titanate, and deionized water, stirring at high-speed for 1.5-2 hours to obtain slurry having solid phase content of 60%, adding glass fiber, stirring at 1500-1800 rpm for 40-50 minutes so that the glass fiber is uniformly dispersed in the slurry, obtaining slurry (A), mixing and stirring epoxy resin E-44 and diluent 660A, heating in a water bath at 70-80 degrees C for 3-4 hours, taking out, cooling, adding triglycidyl p-aminophenol, and diethylaminopropylamine, mixing and stirring, adding the slurry (A), and water glass, stirring the mixture at 1800-2000 rpm for 40-50 minutes, adding polyacrylamide, and continuing high-speed stirring for 1-2 hours.
