Abstract

The invention discloses an environment-friendly composite antifouling paint, which comprises organic resin, spicy natural plants, non-toxic anti-mildew fungicide, inorganic pigment and filler, auxiliary agent, exudation aid and solvent through physical mixing. The above-mentioned organic resin is one or more of epoxy asphalt, polyurethane, acrylic acid, chlorinated rubber, and chloroether resin, the spicy natural plant is mustard oil or capsaicin, and the non-toxic anti-mold fungicide is metal-free N -2.4.6 Trichlorophenylmaleimide or benzisothiazolinone organic matter, pigments and fillers are titanium dioxide, talc, iron oxide red, zinc oxide, bentonite, one or more kinds, additives There are leveling agent, defoaming agent, dispersant, exudation aid is rosin, and solvent is one or more of aromatic hydrocarbons, esters, and ketones. The invention has the characteristics of being non-toxic, not polluting the marine environment, having wide application fields and the like. It has the function of antibacterial and preventing the growth of marine organisms, and has the effect of preventing marine organisms from fouling.

Description

technical field [0001] The invention relates to marine environment-friendly antifouling paint, in particular to an environment-friendly composite antifouling paint. Background technique [0002] Most of the traditional marine antifouling coatings are inorganic or organic substances such as Cu, Sn, Hg and other metals added to the paint. The release of these toxic substances not only effectively prevents the adhesion of marine organisms, but also pollutes the marine environment and causes biological variation. , destroy the ecological balance of the ocean, and bring harm to human health. In this regard, the International Maritime Organization promulgated that since January 1, 2003, all marine paint and coating companies are prohibited from producing, and marine vessels are prohibited from using organic tin and other toxic antifouling coatings. Therefore the development of long-acting and non-toxic environment-friendly antifouling coatings is the trend and direction of the de...
