NOVELTY - Metal surface anticorrosive paint comprises 50-80 pts. wt. aqueous epoxy resin, 10-20 pts. wt. aluminum aqueous compound, 10-20 pts. wt. rare earth compound, 1-5 pts. wt. curing agent, 5-25 pts. wt. titanium dioxide, 10-20 pts. wt. calcium carbonate, 10-20 pts. wt. graphene, 8-12 pts. wt. silica sol, 1-5 pts. wt. coupling agent, 1-5 pts. wt. atifoaming agent, 5-15 pts. wt. dispersing agent, 1-3 pts. wt. thickener, and rest is deionized water. USE - Metal surface anticorrosive paint. ADVANTAGE - The metal surface anticorrosive paint has excellent isolating function, good protecting and corrosion resistant effect and has wide material source, is simple to prepare, easy to operate and prepared in cost effective manner, which meets the requirement of the metal surface anti-corrosive treatment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing metal surface corrosion-resistant paint, which involves: (A) adding Waterborne epoxy resin, titanium dioxide, calcium carbonate, graphene and silica sol into the reaction vessel, and introducing inert gas while stirring at a certain speed to deoxidize the raw material to obtain a coating base material; (B) uniformly mixing aluminum water compound and the rare earth compound and ultrasonically dispersing, and then heating and stirring in a water bath for certain period of time, rinsing and drying to obtain first mixture; (C) Mixing first mixture with the base material, then heating under high pressure and constant stirring to complete the binding reaction; (D) extruding, Granulating to obtain composite particles, refining into a dry powder in an ultrafine pulverizer, and selecting particles of suitable particle size by sieving, and miixng particles with deionized water in proportion to obtain second mixture; (E) adding second mixture to the stirring tank, using high-speed stirring, adding high-speed disperser, stepwise curing agent, coupling agent, defoaming agent and thickening agents; and (F) dispersing through a high speed disperser, and stirring to give a corrosion resistant coating.
