Abstract

The invention relates to an environment-friendly antifouling marine paint preparing method and belongs to the field of antifouling paint synthesis. The method is characterized in that the base material of antifouling paint is synthetized by means of macromolecule prepolymer, zinc hydroxide and organic dicarboxylic acid according to the synthetic route of R[1]AH+2Zn (OH)[2]+HOOCR[2]COOH+R[3]AH->R[1]AZnOOCR[2]COOZnAR[3], and then mixed rust-resisting pigment and auxiliaries are added for fixation to obtain the environment-friendly antifouling marine paint. The preparing process is simple, production is easy, the prepared antifouling marine paint meets the ocean protection environment, antifouling property is good, durability is high, and the preparing antifouling marine paint can be widely applied to marine facilities such as a ship body, a drilling platform and a wharf.

Description

technical field [0001] The invention relates to the synthesis field of antifouling paint, in particular to a preparation method of an environment-friendly marine antifouling paint. Background technique [0002] At present, in order to reduce the damage caused by fouling or corrosion of marine organisms on hulls, docks, and drilling platforms, coating antifouling coatings on the surface is still the only widely applicable, economical and efficient important method to solve this problem. The film-forming substances of marine antifouling coatings are generally high-molecular organic compounds. Antifouling agents generally use active organic salts, and some Chinese medicinal materials solvent extracts and metal oxides are compounded. Nanotechnology is also used to combine nano-silver particles, oxidized Zinc pyrithione zinc or other organic antifouling agents are composite antifouling agents. These antifouling coatings either contain high content of organometallic compounds suc...
