NOVELTY - Graphene heavy-duty anti-corrosion and wear-resistant coating comprises component A including 20-60 pts. wt. aliphatic isocyanate, 10-20 pts. wt. polyacrylamide, 10-30 pts. wt. polyester polyol, 10-15 pts. wt. modified graphene and component B including 40-70 pts. wt. isocyanate, 10-20 pts. wt. amino-terminated polyether, 10-20 pts. wt. chain extender, and 10-20 pts. wt. polyurea modified reinforced composite filler. USE - The graphene heavy-duty anti-corrosion and wear-resistant coating is useful for factory in severe environment offshore and rubbish processing. ADVANTAGE - The coating: has adhesive force of high as 14.5 MPa, salt mist 3360 hours, wear loss is less than or equal to20% (500 revolutions/750 g), and water resistance 320 hours, ensures the metal outer surface of the device with anti-corrosion and wear-resistant protection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene heavy-duty anti-corrosion and wear-resistant coating, comprising (i) heating 10-30 pts. wt. polyester polyol to 100-100degrees Celsius under inert environment, dehydrating under the vacuum pressure, cooling to 50-60degrees Celsius, adding 20-60 pts. wt. aliphatic isocyanate, 10-20 pts. wt. polyacrylamide and 10-15 pts. wt. modified graphene to form semi-prepolymer, reacting at 70-100degrees Celsius for 3-4 hours to obtain the A component; (ii) adding 10-20 pts. wt. amino-terminated polyether and 10-20 pts. wt. chain extender under the condition of 50-80degrees Celsius, stirring and mixing uniformly, then adding 40-70 pts. wt. iso-hydrogen ester, continuously stirring for 30 minutes, adding 10-20 pts. wt. polyurea modified reinforced composite filler, uniformly stirring at 400-800 revolutions/minute under the heating condition of 50-80degrees Celsius, reacting for 3 hours to obtain the B component; and (iii) spraying the A and B components according to the volume ratio of 1:1 to obtain the coating.
