Problems solved by technology

[0008] However, in order to prevent the adhesion of marine organisms, the existing marine antifouling coatings mostly adopt the method of slow-release toxic additives to prevent the adhesion of marine organisms. However, the release of toxic additives in the ocean will seriously damage the marine environment. Yes, and as tim

Abstract

The invention provides a non-toxic releasing anti-fouling paint and a preparation method thereof. The non-toxic releasing anti-fouling paint comprises a component A and a curing agent, wherein the component A comprises 38-48 of fluorocarbon resin, 13-22 of organic silicon resin, 0.5-4 of dispersing agent, 23-42 of pigment and filler, 0.2-0.6 of defoaming agent, 0.2-0.6 of flatting agent and 6-12 of solvent according to the mass percent, the total percentage of all the materials of the component A is 100%, and the curing agent accounts for 2-8% of the mass of the component A. The non-toxic releasing anti-fouling paint provided by the invention is formed by mainly taking organosilicone modified fluorocarbon resin as a film forming matter and adding pigment, filler, an addition agent and the like; marine organisms can not attach to the surface of the anti-fouling paint through a fine, smooth and compact paint film with the low surface energy; and even if few marine organisms attach to the anti-fouling paint, the marine organisms can not firmly attach to the ship and fall off voluntarily when the speed of a ship is 14-15kn in the sailing process, thus the anti-fouling effect is achieved.

Description

technical field [0001] The present invention relates to antifouling coatings for preventing the adhesion of marine organisms (such as shellfish and seaweeds) to products (such as seagoing vessels, subsea structures and fishing gear) that are used under the sea surface for a long time, and in particular to a non-toxic Material release antifouling paint and preparation method thereof. Background technique [0002] Anti-fouling coatings are used to prevent the ship from being blocked by marine organisms and causing fouling when the ship is sailing in the ocean. Anti-fouling coatings can keep the water-soaked parts smooth and free of dirt. Antifouling coatings can be divided into: contact type, booster type, diffusion type, and self-throwing type, which are mainly used in antifouling projects such as ships, marine structures, and pipelines in seawater and fresh water. [0003] Because sea vessels, subsurface structures, fishing gear, etc. are used under the sea surface for a l...
