Abstract

The invention relates to the field of antibacterial anticorrosive products, especially to a graphene-modified antibacterial anticorrosive paint. Raw materials of the antibacterial anticorrosive paintcomprise, by weight, 30-50 parts of epoxy resin, 15-35 parts of modified diatomite, 0.5-10 parts of a graphene material, 0.5-1 part of nano-silver particles, 8-20 parts of a filler, 1.5-6 parts of anauxiliary agent, 13-15 parts of nano-silver cooper-supported POSS-based resin and 16-25 parts of water. The prepared graphene-modified antibacterial anticorrosive paint can solve practical problems inthe fields of ship, marine equipment, granary, etc. which have antibacterial and anticorrosive requirements. The product has good economic benefit, and energy materials are saved. The product has excellent adhesion and good wear resistance in the aspects of steel structures, metal plates, etc., and can be resistant to high and low temperature, high salinity and bacterial corrosion to achieve theantibacterial and anticorrosive effect.

Description

technical field [0001] The invention relates to the field of antibacterial and anticorrosion coating products, in particular to a graphene-modified antibacterial and anticorrosion coating. Background technique [0002] The annual economic loss caused by corrosion in the world accounts for about 4% to 5% of GDP, of which marine corrosion accounts for 1 / 3, which hinders the development of marine economy. On average, large ships need to be docked for antibacterial and anticorrosive coating every 5 years It consumes a lot of anti-corrosion and antibacterial materials, which also delays the normal operation of ships, as do other marine facilities; there are also granaries closely related to our lives, most of which have special metal plates, pipes, It is composed of materials such as concrete structure, and has strict requirements for antibacterial and anti-corrosion. [0003] At present, many antibacterial and anticorrosive materials with excellent performance on the market con...
