Abstract

The invention discloses an environmental-protection type multi-element collaborative marine anti-fouling coating. The coating is composed of anti-fouling coating matrix resin containing an anti-fouling active group, a wetting and dispersing agent, a mixed organic solvent, a non-toxic anti-fouling agent, a pigment filler, a levelling agent, a defoaming agent and an anti-settling agent. The coating is non-toxic, does not pollute the environment, and is mainly applied in ship fouling resistance.

Description

technical field [0001] The invention relates to an environment-friendly marine antifouling paint, in particular to a non-toxic, long-acting, broad-spectrum environment-friendly multi-component synergistic marine antifouling paint, which is used for the antifouling of ocean-going ships. Background technique [0002] my country is vigorously developing the marine industry. Marine biofouling has a great negative impact on the life and service performance of marine equipment. Sea organisms adhere to increase the frictional resistance of ships, which affects the speed of ships and increases energy consumption. At the same time, marine biofouling can accelerate the aging of the paint film and aggravate the corrosion of the hull, which is extremely harmful. The most effective way to prevent biofouling is to apply antifouling coatings, so various antifouling coatings for ships have emerged as the times require. Self-polishing antifouling coatings containing organotins (TBTs) have...
