Embodiment 1

[0025]1 part by weight of polytetrafluoroethylene and 4 parts by weight of polyether-modified siloxane were completely dissolved in a mixed solvent of 3 parts by weight of toluene and acetone (v:v=1:1). Then 5 parts by weight of zinc oxide was added thereto, and dispersed twice with a sand mill. Add 1 part by weight of a leveling agent to the resulting dispersion mixture, and stir at 1500 rpm for 30 minutes with a high-speed disperser. Finally, the remaining 2 parts by weight of the mixed solvent was added thereto and stirred to obtain an antifouling coating composition.

Embodiment 2

[0027] 20 parts by weight of polyvinylidene fluoride and 5 parts by weight of polydimethylsiloxane were completely dissolved in 15 parts by weight of ethyl acetate solvent. Then 1 part by weight of titanium oxide was added thereto, and dispersed twice with a sand mill. 3 parts by weight of a leveling agent was added to the obtained dispersion mixture, and stirred at 1500 rpm for 30 minutes with a high-speed disperser. Finally, the remaining 5 parts by weight of the solvent was added thereto and stirred to obtain an antifouling coating composition.

Embodiment 3

[0029] 7.5 parts by weight of polychlorotrifluoroethylene and 7.5 parts by weight of polyester-modified siloxane were completely dissolved in a mixed solvent of 20 parts by weight of chloroform and butanone (v:v=1:1). Then 10 parts by weight of zinc oxide was added thereto and dispersed twice with a sand mill. 5 parts by weight of a leveling agent was added to the obtained dispersion mixture, and stirred at 1500 rpm for 30 minutes with a high-speed disperser. Finally, the remaining 5 parts by weight of the mixed solvent was added thereto and stirred to obtain an antifouling coating composition.

Abstract

The invention relates to an anti-fouling paint composition. Film-forming substances of the anti-fouling paint are fluororesin and organic silicon resin. The paint composition comprises the components in parts by weight: 5-25 parts of film-forming substance, 5-25 parts of organic solvent and 1-10 parts of pigment. The anti-fouling paint also contains a leveling agent. According to the invention, the fluororesin and organic silicon resin are used as the film-forming substances, the characteristic of low surface energy of the film-forming substances is utilized, and other auxiliary agents are matched to obtain the anti-fouling paint; and the obtained anti-fouling paint has no harm to human body and ocean environment, and has better anti-fouling action on biological dirt. The anti-fouling paint composition is suitable for antifouling of fishing nets, vessels, underwater equipment and other ocean equipment, and is free of mercury or organo-tin compounds capable of causing organic solvent pollution on the sea.

Description

technical field [0001] The invention relates to an antifouling coating composition, in particular, the invention relates to an antifouling coating composition using fluororesin and organic silicon resin as film-forming substances. Background technique [0002] Many marine organisms such as blue mussels, common turtlelimpets, mosses, diatoms, oysters, pearl oysters, sponges, turbanshells, sealettuces, sea squirts (sea squirt) and the like live in sea organic solvents, and these marine organisms attach to underwater equipment, ships, lifesaving belts, port facilities, farms, fishing nets, etc., causing damage to these marine equipment. Especially if these marine organisms attach to the bottom of the ship, the surface of the ship becomes rough and requires frequent maintenance. In addition, when the roughness of the ship's surface reaches 0.01mm, the fuel consumption of the ship will increase by 0.3%-1.0%. This can cause even more serious problems for larger vessels where fue...
