Abstract

The invention discloses an antifouling coating used for ships. The antifouling coating comprises the following raw materials in parts by weight: 63-66 parts of castor oil modified waterborne polyurethane, 24-27 parts of phenolic resin, 12-15 parts of polytrifluorochloroethylene, 11-14 parts of powdery ethylene propylene diene monomer, 15-18 parts of active calcium silicate, 5-7 parts of ultrafine calcium carbonate, 4-5 parts of precipitated barium sulfate, 11-13 parts of sepiolite powder, 1.1-1.4 parts of aluminium zirconium coupling agent TL-4, 0.2-0.5 part of curing agent, 0.5-0.8 part of mildew preventive and 20-23 parts of pigments. The antifouling coating has excellent hydrophobicity, oleophobicity, antifouling property and corrosion resistance, is difficult for marine organisms to adhere to, and is suitable for the service environments of ships.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antifouling coating for ships. Background technique [0002] Driven by the strong growth of China's economy, China's coating industry has shown a trend of rapid growth in recent years. In addition to the substantial growth of architectural coatings, non-ship and heavy-duty anti-corrosion coatings have the fastest growth and the highest market share among industrial coatings, including heavy-duty coatings used in many fields such as ships, containers, marine engineering, petrochemicals, railways, highways, and bridges. The output of anti-corrosion coatings has reached more than 1 million tons. There are also many types of existing marine coatings, but they cannot well deal with the problems of seawater corrosion, sudden changes in marine climate and adhesion of marine organisms. Contents of the invention [0003] The technical problems in the basic background technology. T...
