Problems solved by technology

The main toxic materials (such as cuprous oxide, etc.) and resins of tin-free self-polishing antifouling coatings lose their toxicity due to rapid degradation after being released from the paint film. Therefore, compared with organotin antifouling coatings, they are relatively less harmful to the marine environment. Small, but the existing tin-free self-polishing antifouling coating has the disadvantage of poor antifouling and drag reduction effect

Abstract

The present invention belongs to the technical field of antifouling and anti-drag paint, relates to antifouling and anti-drag paint for marine engineering, in particular to cationic type antifouling and anti-drag composite functional paint, and further relates to a coating adopting the paint. The cationic type antifouling and anti-drag composite functional paint comprises: granular cationic type filler, film-forming resin, a curing agent and a diluent. According to the cationic type antifouling and anti-drag composite functional paint provided by the invention, the granular cationic type filler can be micro particles with positive charges on surface. The micro particles, via the film-forming resin, are insulated from one other in the coating, so that an electrode potential of the composite functional coating is positive in the seawater, thereby effectively preventing the adhesion and fouling of marine organisms, and significantly reducing the surface frictional resistance.

Description

Technical field [0001] The invention belongs to the technical field of anti-fouling and drag-reducing paints, and relates to an anti-fouling and drag-reducing paint for marine engineering, in particular to a cationic anti-fouling and drag-reducing composite functional paint, and also relates to a coating prepared by using the paint . Background technique [0002] Marine equipment such as surface ships and underwater vehicles will be attached and defaced by marine organisms in the port of anchor, and even during navigation. Nearly 4000 species of fouling organisms have been reported in seas around the world. The attachment of marine organisms mainly includes two categories: microbial attachment (mainly bacteria and diatoms) and macro biological attachment (such as barnacles, mussels, bryozoans and seaweeds, etc.). The attachment and fouling of marine organisms will increase navigation resistance, reduce ship speed, and increase fuel consumption; it will also increase the difficu...
