Abstract

The invention provides a colorized antifouling paint without cuprous oxide, which comprises the following components with the weight percentage of: 10-25 percent of resin, 1-2 percent of pigment, 14-33 percent of stuffing, 15-30 percent of antifouling agent, 5-10 percent of addition agent, and 10-25 percent of solvent, wherein, the antifouling agent comprises following components with the weight percentage of: 50-95 percent of cuprous thiocyanate, 3-35 percent of zineb, and 2-15 percent of copper pyrithione. The antifouling paint of the invention has no cuprous oxide, silicon or fluororesin; when the antifouling paint of the invention is applied to coating, various colors can be presented below a waterline of a vessel. The product is in accordance with requirements for environmental protection; the preparation method is simple; energy can be saved; the cost is low. The prepared antifouling paint has good film-forming performance under normal temperature; the storage stability and antifouling performance are excellent; attached organism can be killed effectively.

Description

technical field [0001] The invention relates to a colored antifouling paint for ship bottom antifouling and a preparation method thereof. Background technique [0002] During the sailing and mooring process of the ship, the shell below the waterline is in contact with seawater for a long time, not only being corroded by seawater, but also various animals, plants and microorganisms will grow and reproduce on its surface, which not only corrodes and damages the ship Ship paint (ship bottom paint) makes the paint film perforate and peel off, shortens its service life, and also increases the friction resistance between the hull and sea water, affects its sailing speed, and increases fuel consumption. In addition, the corrosion and damage of attached organisms to marine terminal equipment, seawater cooling pipelines, power plant cooling towers, and offshore drilling platform pillars are also very serious. Therefore, practical preventive measures must be taken. In addition, it al...
