Abstract

The invention discloses a graphene-reinforced epoxy ceramic coating. The graphene-reinforced epoxy ceramic coating is prepared from dolomite, silicon carbide powder, corn starch, polyethylene glycol siloxane, alumina, graphene oxide, aniline, hydrochloric acid, an ammonium persulfate solution, sodium hexametaphosphate, tributyl phosphate, propylene glycol butyl ether, titanium dioxide, magnesium oxide, barium sulfate, alcohol amine diphosphoacyloxy hydroxyacetate titanate, glass fibers, epoxy resin E-44, a diluent 660A, triglycidyl p-aminophenol, diethylaminopropylamine, water glass, polyacrylamide and an appropriate amount of deionized water. The graphene-reinforced epoxy ceramic coating can form a dense and smooth coating layer with excellent characteristics such as firmness the same toceramic, high adhesion, uniform thickness, water resistance, corrosion resistance and excellent electrical insulation performances.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to a graphene-enhanced epoxy ceramic coating and a preparation method thereof. Background technique [0002] Ductile iron pipes are gradually replacing gray iron pipes with the advantages of high strength, good toughness, high reliability and good corrosion resistance. In recent years, with the continuous expansion of urbanization, the demand for pipes, especially large-diameter pipes, continues to rise It is playing an increasingly important role in the transformation of water supply pipes and pipe networks in major cities at home and abroad. As the preferred material for these projects, it is widely used in urban construction water and gas transmission projects. It is a ductile iron pipe. The industry provides a huge market. [0003] Epoxy ceramic is a new type of anti-corrosion coating for cast iron pipe lining. It is a kind of epoxy ceramic coating which is mechanically s...
