Abstract

The invention discloses long-life self-polishing antifouling coating, and relates to high-solid long-life self-polishing ship bottom antifouling coating with antifouling validity of more than three years, in particular to novel marine antifouling coating containing an antifouling agent system without internationally non-permissible toxins and reaching the national environment-friendly requirements. The long-life self-polishing antifouling coating is characterized by comprising copper acrylic resin, composite antifouling agents, pigments, fillers, anti-sedimentation agents, solvents, and the like, and being red brown. The coating is applicable to the ship bottom of a ship as an antifouling coating, can effectively prevent the ship bottom from fouling by the marine organisms within 3-5 years, does not contain organic tin (TBT) and DDT toxins, is environment-friendly and constructed conveniently, can keep the speed of a ship uninfluenced, and saves fuel; and the coating further has good overcoatability.

Description

technical field [0001] The invention relates to an antifouling paint, in particular to a high-solid long-acting self-polishing antifouling paint for ship bottoms with an antifouling effect of more than three years, which contains a composite antifouling agent system and does not contain internationally banned poisonous materials , to meet the national environmental protection requirements. Background technique [0002] The primary problem encountered by ships navigating in the sea is the attachment and fouling of marine organisms to the bottom of the ship. More than 200,000 species of marine organisms have been preliminarily proven, and some organisms grow by attaching to fixed objects. The bottom of a ship below the waterline is the main base for organisms attaching, and marine organisms attaching to them has brought great harm to ship navigation. The amount of marine organisms in the South my country Sea area is as high as 20 kg per square meter during the peak growth sea...
