▎ 摘  要

NOVELTY - Epoxy thick paste type anti-corrosion coating comprises 12-17 pts. wt. epoxy resin, 7-9 pts. wt. modified graphene, 0.1-0.3 pts. wt. anti-foaming agent, 0.4-0.6 pts. wt. leveling agent, 20-30 pts. wt. calcium carbonate, 2-4 pts. wt. curing agent, 1-1.5 pts. wt. thixotropic agent and 10-15 pts. wt. water. USE - The coating is useful for ship body, marine engineering device, large steel device, component and pipeline. ADVANTAGE - The coating has excellent anti-corrosion performance, wear resistance and corrosion resistance, excellent dry film thickness; ensures the dry film surface without air hole, no crack, smooth and flat and reduced permeability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing epoxy thick paste type anti-corrosion coating comprising (a) stirring the epoxy resin and modified graphene at 300-400revolutions/minute for 10-20min to obtain component A, (b) adding anti-foaming agent, leveling agent, calcium carbonate, curing agent and water to component A, stirring at 500-600revolutions/minute for 40-50 minutes to obtain component B and (c) adding the thixotropic agent to component B and stirring at 450-550revolutions/minute for 90-120 minutes to obtain the finished product.
