Antifouling modified asphalt paint and preparation method thereof

Abstract

The invention discloses antifouling modified asphalt paint. The paint is characterized by being prepared from the following raw materials in parts by weight: 13-16 parts of E-12 epoxy resin, 4-6 parts of benzidine, 1-2 parts of melamine, 2-3 parts of borax, 0.4-0.8 part of zinc pyrithione, 0.3-0.6 part of sodium dichloroisocyanurate, 0.5-1.0 part of 1,3-dibromo-5,5-dimethylhydantoin, 2-4 parts of bois de rose oil, 2-3 parts of nano fluorocarbon, 1-3 parts of methylenedithiocyanate, 1-3 parts of 2-mercaptopyridine zinc oxide, 1-3 parts of bamboo fiber, 2-3 parts of dimethicone, 2-3 parts of versatate-acrylate emulsion, 2-3 parts of white carbon black, 1-2 parts of vermiculite powder, 0.5-1.0 part of octadecanol polyoxyethylene ether, 32-38 parts of modified asphalt, 6-9 parts of modified waste resin sand, 11-13 parts of xylene, 8-11 parts of diphenyl ether and 3-5 parts of tannin. The paint adopts mutually synergetic effect of non-toxic aqueous biocide zinc pyrithione, sodium dichloroisocyanurate and 1,3-dibromo-5,5-dimethylhydantoin, is capable of effectively preventing attachment of marine organisms from polluting a water body, has weather resistance, heat resistance, low-temperature resistance and chemical drug resistance by adding nano fluorocarbon, has unique non-adhesive property and low friction, and has the effects of reducing environment pollution, improving antifouling property and anti-aging property of a paint film by adding the modified waste resin sand.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an antifouling modified asphalt paint and a preparation method thereof. Background technique [0002] The massive attachment of marine organisms such as barnacles, seaweed, and shellfish to marine facilities can lead to slowdown of ship speed, increase of fuel, corrosion and breakage of ship bottom, drilling platform, buoys, bridge piers, etc., blockage of seawater pipelines and cage nets , has brought a lot of disasters to the process of human development of the ocean. For a long time, the most widely used self-polishing coatings, such as organic tributyltin and organic copper, form a poisonous concentration layer around the material that is toxic to marine plant spores and animal larvae, thereby playing an antifouling role. However, this method releases toxic agents while preventing pollution, leading to water pollution and biological variation, which poses safety ha...

Problems solved by technology

The various organic resins or organic and inorganic compounds contained in a large amount of waste resin sand piled up are slow to decompose, causing serious harm to the soil, and can acidify the soil. Some compounds will flow into rivers with rain, polluting water sources, people Once consumed, it will cause serious damage to people's health
