Abstract

The invention discloses a graphene-containing marine anticorrosion antifouling coating and a preparation method thereof. Graphene having an antibacterial function is used as a filling material and is added into epoxy resin by surface modification, and the nano composite antifouling coating having antibacterial and anticorrosion properties is prepared. The graphene is added into the epoxy resin to form the marine antifouling coating; the excellent characteristics of the two materials are fully combined, so the coating has both the antifouling characteristic and the anticorrosion characteristic, that is to say, graphene and the epoxy resin are composited, so the antibacterial property of graphene and the anticorrosion property of the epoxy resin are organically combined jointly, and thus the novel antifouling coating having both the anticorrosion property and the antifouling property is developed.

Description

technical field [0001] The invention relates to an antifouling paint for marine metal components and a preparation method thereof, more specifically, to a graphene-containing marine antifouling paint and a preparation method thereof. Background technique [0002] Biofouling is a major problem that has plagued the development of the marine shipbuilding industry for a long time; the research results show that marine fouling caused by marine organisms on the surface of the ship will increase the roughness of the hull surface, reduce the speed of the ship, increase fuel consumption, and will contribute to the future development of the hull. Pollution and cleaning cause a lot of capital and manpower consumption. According to statistics, biofouling will increase the fuel consumption of ships by 40%; in addition, the annual economic loss caused by corrosion in my country is at least 90 billion yuan, and marine corrosion accounts for more than 30%. It accounts for about 30% of the t...
