Problems solved by technology

[0003] Now in order to better improve the use of ships, it is necessary to evenly apply paint on the outer wall of the ship for protective treatment, but the existing paints are not ideal for preventing marine organisms from adhering, which is not conducive to the long-term use of ships. At the same time, it is inconvenient to carry out quantitative filling when filling paint

Abstract

The invention discloses a marine coating for preventing adhesion of marine organisms and a processing technology, and relates to the technical field of coatings. The marine coating for preventing adhesion of the marine organisms is prepared from the following raw materials in parts by weight: 9 to 12 parts of nano silicon dioxide, 4.5 to 7.5 parts of castor oil modified waterborne polyurethane, 2.3 to 4.5 parts of vinyl polydimethylsiloxane, 10 to 12 parts of hollow glass beads, 13 to 18 parts of epoxy resin, 8.3 to 11.8 parts of polytrifluorochloroethylene, 1.5 to 1.8 parts of titanate coupling agent, 4.5 to 5.8 parts of polyacrylamide and 12 to 24 parts of defoaming agent. The marine coating for preventing adhesion of the marine organisms has good hydrophobicity, lipophobicity, antifouling property and corrosion resistance, can effectively prevent adhesion of marine organisms, is suitable for the use environment of the surface of a ship, ensures actual use of the coating, and is convenient for quantitative filling during filling.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to ship coatings and processing techniques for preventing marine organisms from adhering. Background technique [0002] There are more than 18,000 species of appendages and 600 species of appendages in the sea areas of the world. 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 adhesion of marine organisms also destroys the paint film and accelerates the corrosion of the steel plate, which not only increases the number and time of ship maintenance, but also reduces the service rate of the ship. [0003] Now in order to better improve the use of ships, it is necessary to evenly apply paint on the outer wall of the ship for protective treatment, but the existing paints are not ideal for preventing marine organisms from adhering, wh...
