Abstract

The invention discloses environment-friendly marine antifouling coating for a fishing boat, and relates to boat bottom antifouling coating used in a fishing boat, in particular to marine antifouling coating containing an antifouling agent system without cuprous oxide and other internationally non-permissible toxins, reaching the national environment-friendly requirements and having about one-year antifouling validity. The marine antifouling coating is characterized by comprising acrylic resin, composite antifouling agents, pigments, fillers, anti-sedimentation agents, solvents, and the like. The coating is suitable to be used at the boat bottom of a steel fishing boat or a wood fishing boat as the antifouling coating, can effectively prevent the boat bottom from fouling by marine organisms within one year, has low price, and is environment-friendly and constructed conveniently.

Description

technical field [0001] The invention relates to an antifouling coating, in particular to a marine antifouling coating for fishing vessels with an antifouling period of about one year, which contains a composite antifouling agent system, does not contain cuprous oxide and other internationally banned poisonous materials, and meets the national environmental protection requirements. Dirty paint. Background technique [0002] Antifouling paint is a special coating that inhibits and prevents the attachment and growth of marine organisms on marine steel structures such as ships by gradually releasing the contained active ingredients (poison) into seawater at a very low rate, thereby maintaining The smooth outer surface of the hull and the integrity of the coating can minimize fuel consumption and prolong the service life of the coating under the premise of ensuring normal speed, reducing unnecessary maintenance expenses. [0003] The main antifouling agent used in fishing boat a...
