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

Embodiment 1

[0048] The cationic anti-fouling and drag-reducing composite functional coating provided in this embodiment consists of:

[0049]

[0050] The anti-fouling and drag-reducing coating prepared by the above coating is prepared by a preparation method comprising the following steps:

[0051] Weighing in parts by weight: 20 parts of aluminum powder particles with positive charges on the surface, 50 parts of fluorocarbon resin, 5 parts of isocyanate, and 5 parts of xylene, stirred and mixed evenly to obtain an antifouling and drag reducing coating;

[0052] Before the painting operation, first clean up the oil, dust or rust and other pollutants on the surface of the substrate, and then apply anti-rust paint (616 chlorinated rubber iron red thick paste type) and epoxy joint on the surface of the substrate by spraying. Paint (FJ-18), after the paint film of antirust paint and epoxy connecting paint is solidified, carry out the coating operation of the composite functional coating o...

Embodiment 2

[0055] The cationic anti-fouling and drag-reducing composite functional coating provided in this embodiment consists of:

[0056]

[0057] The anti-fouling and drag-reducing coating prepared by the above coating is prepared by a preparation method comprising the following steps:

[0058] Weigh in parts by weight: 10 parts of titanium dioxide particles with positive charge on the surface, 60 parts of fluorocarbon resin, 15 parts of silicone resin, 15 parts of isocyanate, 20 parts of xylene, stir and mix evenly to prepare antifouling and drag reducing coating ;

[0059] Before the painting operation, first clean up the oil, dust or rust and other pollutants on the surface of the substrate, and then apply anti-rust paint (616 chlorinated rubber iron red thick paste type) and epoxy joint on the surface of the substrate by spraying.

Abstract

Cationic type antifouling and anti-drag composite functional paint and a coating using the paint. The paint comprises a granular cationic type filler, film-forming resin, a curing agent, and a diluent. The granular cationic type filler is microparticles having positive charges on the surface. The coating can effectively prevent the adhesion and fouling of marine organisms, and significantly reduce the surface frictional resistance.

Description

technical field [0001] The invention belongs to the technical field of anti-fouling and drag-reducing coatings, and relates to an anti-fouling and drag-reducing coating for marine engineering, in particular to a cationic anti-fouling and drag-reducing composite functional coating, and also relates to a coating prepared by using the coating . Background technique [0002] Marine equipment such as surface ships and underwater vehicles will be attached and fouled by marine organisms when they are moored in ports or even during navigation. Nearly 4,000 species of fouling organisms have been reported in sea areas around the world. The attachment of marine organisms mainly includes two categories: microbial attachment (mainly bacteria and diatoms) and macroscopic biological attachment (such as barnacles, mussels, bryozoans and seaweeds, etc.). Marine bio-adhesion and fouling will increase navigation resistance, reduce ship speed, increase fuel consumption; it will also increase ...
