Marine antifouling coating with bionic synergistic effect and preparation method thereof

Abstract

The invention belongs to the technical field of marine anticorrosion and antifouling, and particularly relates to a marine antifouling coating and a preparation method thereof. The marine antifoulingcoating with the bionic synergistic effect comprises a base body layer, and microtextures are evenly distributed on the surface of the base body layer. The micro-texture protrudes out of the surface of the base body layer. The micro-texture is in a cylindrical shape, a cross shape, a rib shape or a groove shape. The surface of the marine antifouling coating is provided with cylindrical, cross-shaped, rib-shaped and groove-shaped micron-sized textures, phenyl methyl silicone oil and capsaicine are added into the coating to serve as seepage-imitating antifouling agents; in order to solve the problem of the seepage rate of the antifouling agents, ZnO with the nanometer particle size is added, so that the crosslinking density of the coating is enhanced, and the antifouling property of the coating is improved. The mechanical property is improved, and the seepage rate of the antifouling agent is controlled, so that the purpose of prolonging the service life of the coating is achieved.

Description

technical field [0001] The invention belongs to the technical field of marine anticorrosion and antifouling, and in particular relates to a marine antifouling coating and a preparation method thereof. Background technique [0002] Marine biofouling has caused a series of adverse effects on the marine industry, marine engineering, and marine equipment, such as affecting fishery output, blocking submarine pipelines, and increasing facility maintenance costs. For ships, biofouling will cause harm in the following aspects: (1) increase the ship's action resistance, reduce its maneuverability, and greatly increase fuel consumption; (2) destroy the ship's protective coating and corrode the metal substrate. Fouling organisms will affect the pH and oxygen concentration in the attachment area, thereby accelerating the corrosion of ships; (3) increasing the frequency of ship docking maintenance, resulting in waste of time and resources. Fouling organisms adhere to the surface of the...
