Environment-friendly bionic ocean corrosion resisting paint

Abstract

The invention discloses environment-friendly bionic ocean corrosion resisting paint. The environment-friendly bionic ocean corrosion resisting paint is characterized by being prepared from, by weight, 20-25 parts of fluorinated acrylic ester, 22-24 parts of epoxy phenolic resin, 12-15 parts of silicone rubber, 10-12 parts of silicon-aluminum-barium-calcium alloy powder, 3-4 parts of titanium dioxide, 2-4 parts of biological preservative, 3-4 parts of adhesive force thickener, 5-7 parts of filler and 24-28 parts of solvent. Friction coefficient can be reduced effectively, and hydrophobicity can be improved; through the synergistic effect of the filler and the adhesive force thickener, contamination release performance is improved, so that adhesion of attachments does not occur easily or is not firm; the biological preservative has an effective adhesion inhibition effect and has a quite high mussel adhesion preventing capacity; P-cinnamic acid sulfate has a strong marine bacteria and barnacle adhesion inhibition effect, is purely natural and free of pollution, and has a good environment protection effect; the corrosion resisting paint can be sprayed or brushed, and a coating is resistant to corrosion and suitable for severe marine climate.

Description

technical field [0001] The invention belongs to the technical field of marine coatings, and in particular relates to an environment-friendly bionic marine anti-rust coating. Background technique [0002] Marine seawater corrosion is mainly chloride ion corrosion. Marine chloride ions can destroy the protective layer of metal oxide film, forming pitting corrosion or pitting corrosion, and intergranular corrosion of metals. Under the effect of tensile stress on the metal, the area where the passivation film is destroyed will produce cracks and become the anode area of ​​the corrosion battery. Continuous electrochemical corrosion may eventually lead to the fracture of the metal. The adhesion of marine organisms brings great harm to ships and marine facilities. On the one hand, these marine organisms adhere to the surface of artificial facilities in the sea, which will increase the ship's navigation resistance, block pipelines and breeding nets, and affect the normal operation o...

Problems solved by technology

Under the action of tensile stress on the metal, cracks will appear in the area where the passivation film is destroyed, which will become the anode area of ​​the corrosion battery. Continuous electrochemical corrosion may eventually lead to the fracture of the metal.

The adhesion of marine organisms brings great harm to ships and marine facilities. On the one hand, these marine organisms adhere to the surface of artificial facilities in the sea, which will increase the ship's navigation resistance, block pipelines and breeding nets, and affect the normal operation of acoustic instruments and other offshore equipment. Use, increase the burden of offshore oil and gas exploration platforms, accelerate metal corrosion and other serious hazards, resulting in huge losses in marine military activities, marine transportation, industry and aquaculture production

At present, cuprous chloride antifouling agent coatings occupy a dominant position in the field of antifouling, but because copper elements will accumulate in large quantities in the ocean, especially in harbors, causing a large number of algae to die, thereby destroying the ecological balance of the marine environment, so will eventually be disabled
