Problems solved by technology

At present, in-depth research has been carried out on low surface energy antifouling materials at home and abroad, but there is still a lack of further construction of microstructured surfaces using low surface energy materials to improve hydrophobicity and antifouling effects.
To sum up, there are generally disadvantages in the prior art that antifouling materials have a destructive impact on the environment or the preparation process is complicated and the effect is limited.

Abstract

The invention belongs to the technical field of antifouling material processing and relates to a method for preparing an antifouling material with surface of spherically raised microstructure which is formed by direct film forming. The antifouling material prevents marine growth from adhering to the surfaces of the ship and marine structures under marine environment. The method is characterized by first utilizing hydrogen-containing silicone oil and allyl methacrylate for hydrosilylation to synthesize a silicone component containing polymerizable double bonds, carrying out free radical copolymerization on the silicone component and acrylonitrile and acrylate monomers to form acrylate resin mixed liquor hinged with silicone gel particles, mixing the mixed liquor with resins and then coating films, thus obtaining the antifouling material. The mixed resin material has the characteristic of low surface energy. The characteristic of spherically raised microstructure is formed, thus improving the hydrophobic property of the antifouling material, so that the antifouling material prevents marine organisms from being contaminated. With the hydrophobic property being improved, the antifouling material reduces the possibility of organism adhesion, has no devastating impacts on the environment and has good application prospect, reduced surface energy, strong capability of preventing adhesion of diatom, simple and easily controlled preparation process and low cost.

Description

Technical field: [0001] The invention belongs to the technical field of antifouling material processing, and relates to a method for preparing an antifouling material on the surface of a spherical protrusion microstructure by directly forming a film to prevent marine organisms from adhering to the surface of ships and marine structures in a marine environment. Background technique: [0002] At present, there are a large number of marine organisms in seawater. These marine organisms will adhere to the surface of ships and structures that have been in the seawater environment for a long time, and this adhesion will increase the resistance of the ship and seriously affect the speed of the ship. It will increase fuel consumption and damage the anti-corrosion coating on the surface of ships and structures, which will cause corrosion and damage on the surface of the hull and structures, seriously affecting their safety. Therefore, it is very important to find a suitable way to pre...
