NOVELTY - Glass anticorrosive coating comprises epoxy resin, polyurethane resin, additive, antifoaming agent, graphene, water, oily dissolved liquid and titanium dioxide, and is prepared by (i) placing graphene in container, adding potassium permanganate, oxidizing to obtain brown phenolic hydroxyl group and epoxy group graphite sheet, (ii) placing the graphene oxide to be treated in a storage cylinder, and adding water, oily dissolved liquid and graphene, (iii) putting the mixture in ultrasonic wave instrument to carry out ultrasonic dispersion to obtain dispersed liquid, (iv) placing the dispersed liquid in storage cylinder, adding graphene, ultrasonically dispersing to obtain composite dispersion liquid, (v) adding epoxy resin, polyurethane resin, graphene and titanium dioxide to composite dispersion liquid, and driving and stirring through stirring equipment to obtain graphene anticorrosive coating, and (vi) adding antifoaming agent into the graphene anticorrosive coating. USE - As glass anticorrosive coating. ADVANTAGE - The method solves the problem of graphene to disperse independently. The coating has excellent water resistance and corrosion resistance, and improved conductivity. DETAILED DESCRIPTION - Glass anticorrosive coating comprises 5-20 pts. wt. epoxy resin, 10-18 pts. wt. polyurethane resin, 2-5 pts. wt. additive, 12-25 pts. wt. antifoaming agent, 1-10 pts. wt. graphene, 20 pts. wt. water, 10-15 pts. wt. oily dissolved liquid and 5-30 pts. wt. titanium dioxide, and is prepared by (i) placing graphene in a container, adding potassium permanganate, oxidizing to obtain a brown phenolic hydroxyl group and an epoxy group graphite sheet, where the graphite sheet layer is subjected to ultrasonic or high-shearing violent stirring and stripping to obtain the graphene oxide, (ii) placing the graphene oxide to be treated in a storage cylinder, and adding water, oily dissolved liquid and graphene, (iii) putting the mixture prepared in (i) in an ultrasonic wave instrument to carry out ultrasonic dispersion to obtain a dispersed liquid, (iv) placing the dispersed liquid in storage cylinder, adding graphene, placing in ultrasonic instrument to carry out ultrasonic dispersion to obtain composite dispersion liquid, (v) adding epoxy resin, polyurethane resin, graphene and titanium dioxide to the composite dispersion liquid, and driving and stirring through stirring equipment to obtain graphene anticorrosive coating, and (vi) adding antifoaming agent into the graphene anticorrosive coating.
