Abstract

The invention discloses universal ship bottom antifouling coating, and relates to universal high-solid self-polishing ship bottom antifouling coating, in particular to novel marine antifouling coating containing an antifouling agent system without cuprous oxide and other internationally non-permissible toxins and reaching the national environment-friendly requirements. The universal ship bottom antifouling coating is characterized by comprising zinc acrylate resin, composite antifouling agents, pigments, fillers, anti-sedimentation agents, solvents, and the like and being of various colors. The coating is applicable to marine engineering or a ship bottom as an antifouling coating, can be used at aluminum substrate surfaces, steel substrate surfaces and waterline positions, can effectively prevent the ship bottom from fouling by marine organisms within 1-2 years, 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 general-purpose high-solid self-polishing antifouling paint for ship bottoms, which can be used on the surface of aluminum and steel substrates and waterline parts, and does not contain cuprous oxide and other international Prohibited toxic materials 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...
