Abstract

The invention discloses a powder coating for a ship surface. The powder coating comprises the raw materials in parts by weight: 75-78 parts of castor oil modified waterborne polyurethane, 23-26 parts of epoxy resin, 8-11 parts of polytrifluorochloroethylene, 8-11 parts of hollow glass microspheres, 14-15 parts of calcium carbonate superfine powder, 4-5 parts of talcum powder, 1-3 parts of organic montmorillonoid, 1.5-1.8 parts of a titanate coupling agent KR-TTS, 0.2-0.5 part of a curing agent, 0.5-0.8 part of a mildew preventive and 20-23 parts of a pigment. The powder coating is excellent in hydrophobicity, oleophobicity, dirt prevention property and corrosion resistance; marine organisms are difficultly to attach to the powder coating, and the powder coating is suitable for the use environment on the ship surface.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a powder coating for ship surfaces. Background technique [0002] Anti-fouling coatings are used to prevent the ship from being blocked by marine organisms and causing fouling when the ship is navigating in the ocean. Anti-fouling coatings can keep the water-soaked parts smooth and free of dirt. Antifouling coatings can be divided into: contact type, booster type, diffusion type, and self-throwing type. They are mainly used in antifouling projects such as ships, marine structures, and pipelines in seawater and fresh water. There are more than 18,000 species of organisms in sea areas around the world. It is an attached animal, and more than 600 kinds are attached plants. After marine organisms are attached to the bottom of the ship, the resistance will be increased, the speed will be reduced, the fuel consumption will increase, and the mechanical wear will increase. The adhesi...
