Problems solved by technology

The preparation process of this method is cumbersome, the cost is high, and the ceramic insulating intermediate coating must have extremely good insulation and anti-penetration properties, otherwise it will cause accelerated corrosion of the substrate and rapid peeling off of the coating.

Abstract

The invention provides a ship sea chest grating copper-based antifouling composite coating. The ship sea chest grating copper-based antifouling composite coating comprises a copper or copper alloy base coating and a self-polishing sealing material coating, wherein a self-polishing sealing material permeates into pores of the copper or copper alloy base coating. According to the ship sea chest grating copper-based antifouling composite coating, a self-consuming organic coating technology is adopted, and a self-polishing sealing material of zinc acrylate resin or acrylic silicone resin is used as a hole sealing agent of the copper-based coating so that it can be guaranteed that a corrosion medium cannot penetrate the coating, the anti-fouling function of the copper-based antifouling coatingcan be guaranteed to achieve stably, then the coating can achieve a good marine organism antifouling effect, and the influence of marine organism on the matrix material is reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of marine ships, and relates to a copper-based antifouling composite coating for a ship's submarine door grid. Background technique [0002] Marine biofouling has always been one of the challenges faced by the marine industry. Submarine door grille is the part where marine biofouling occurs frequently: conventional antifouling coatings are difficult to ensure the adhesion on the grille surface under the scouring of high-speed water flow and the impact of solid impurities, and cannot play an effective antifouling effect. [0003] Cuprous ions can effectively inhibit the growth and aggregation of marine organisms, and cuprous oxide is added as an antifouling agent in many antifouling coatings. Copper or copper alloy itself corrodes in seawater, and it will also release cuprous ions, which inhibit the growth of marine organisms. Therefore, it is often used in marine structures that are sensitive to marine biof...
