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.
