Abstract

The bionic poisonless antifouling paint for ship is prepared with fluororesin, modified fluororesin alkaloid, peptide compound, solvent, ionic water, leveling agent, stuffing, pigment and assistant. The modified fluororesin is preparew with fluoric thiofuran, polyfluoroethylene, fluoric ethylene monomer and solvent and through reaction in the action of initiator. The alkaloid is extracted from marine life seaweed, and the peptide compound is extracted from sponge. The antifouling paint forms paint film on the bottom of ship and under the action of sea water the paint film surface with high crosslinking density and low adhering performance will exude alkaloid and peptide to prevent marine life from attaching. The paint may be also used in the surface treatment of marine drilling platform, underwater pipe, valve and other facilities.

Description

Technical field: [0001] The invention relates to a fluorine-containing paint, which is an anti-fouling paint composed of a fluorine-containing olefin copolymer, a marine organism extract, a solvent and an auxiliary agent. Background technique: [0002] Due to the parasitism and reproduction of marine organisms, especially shellfish, on the bottom of ships in the ocean, the burden of navigation on ships increases, which affects their navigation speed and load efficiency. How to prevent the parasitism of these organisms has become an important topic. After a lot of research, a paint made of tin organic compounds was found, which can effectively inhibit and prevent the growth of these organisms. After years of use, due to the high toxicity of this kind of organotin paints, serious pollution to the marine ecological environment, to a certain extent, affect the natural ecological balance, destroy the living environment of some aquatic organisms, especially for the important ecological...
