Abstract

The invention provides a long-acting environment-friendly ship bottom antifouling paint, a strippable antifouling paint and a ship bottom antifouling treatment method. The long-acting environment-friendly ship bottom antifouling paint contains flaky cuprous oxide and superfine cuprous oxide in a weight ratio of (1-1.5):(1.5-1), wherein the particle size of the flaky cuprous oxide is 200-800 meshes, and the particle size of the superfine cuprous oxide is 20-30nm. The invention also provides a strippable antifouling paint which comprises a perchloro-ethylene resin, superfine cuprous oxide, zinc pyrithione or zinc pyrithione, a mixed solvent, a dispersing agent and an anti-settling agent. The invention also provides a ship bottom antifouling treatment method. The long-acting environment-friendly ship bottom antifouling paint can reach the antifouling period of 5-10 years by adopting the composite organic antifouling compound, is free of international unallowable organotin and DDT toxic materials, and thus, is environment-friendly. The long-acting environment-friendly ship bottom antifouling paint can effectively prevent marine organisms from attached growth, and the paint film has smooth surface.

Description

technical field [0001] The invention relates to a long-acting environment-friendly ship bottom antifouling paint, a peelable antifouling paint and a ship bottom antifouling treatment method, belonging to the technical field of coatings. 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 season. They increase the roughness of the bottom of the ship, reduce the speed of the ship, and increase fuel consumption. According to statistics, half of th...
