Ocean-environmental antifouling coating and preparation method thereof

Abstract

The invention discloses an ocean-environmental antifouling coating and a preparation method thereof. The ocean-environmental antifouling coating is composed of, by weight part, 60-80 parts of silicon-modified acrylic resin, 12-14 parts of talcum powder, 3-5 parts of environmental antifouling agent, 40-60 parts of water-borne acrylic-modified epoxy resin, 1-3 parts of bentonite, 3-5 parts of zinc oxide, 5-6 parts of minerals, 5-7 parts of glyoxal, 4-6 parts of ferric oxide red, 6-8 parts of isophorone, 3-5 parts of silane coupling agent, 4-6 parts of butanol and 1-3 parts of organic solvent. The ocean-environmental antifouling coating contains no hazardous substances such as organic tin and cuprous oxide which can cause severe hazards to marine ecological environment, avoids environment pollution and destruction. By reducing the interface energy and matching with the environmental organic antifouling agent, the ocean-environmental antifouling coating can achieve efficient antifouling performance.

Description

technical field [0001] The invention relates to the field of marine coatings, in particular to a preparation method of a marine environment-friendly antifouling coating. Background technique [0002] The important problem encountered by ships navigating in the sea is the attachment and fouling of marine organisms to the bottom of the ship. Marine fouling organisms attaching to the bottom of the ship will increase navigation resistance, reduce ship speed, and consume more fuel; attaching to marine breeding nets will cause It will block the mesh and reduce the seawater exchange efficiency, which can lead to stunted or even death of cultured fish and shellfish; attach to marine instruments, which will cause signal distortion and performance degradation of the instruments; attach to torpedoes, increase weight and navigation resistance, and cause torpedo imbalance and failure. resulting in heavy losses. Applying antifouling coatings is an important way to solve the problem of fo...

There is also a large amount of expenses each year to compensate for the deceleration caused by the failure of the antifouling paint, and it will cost a lot of money to repaint the antirust and antifouling paint
