Embodiment Construction

[0039] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0040] One of the embodiments provided by the present invention is: a marine antifouling coating with bionic synergistic effect, such as figure 1 As shown, the antifouling coating is mainly composed of a base layer 1 and a micro-texture 2 on the surface of the base layer 1 . Wherein, base layer 1 is the base material that is made of PDMS, and antifouling agents 3 such as simethicone oil, dimethyl diphen...

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...
