Aging-resistant antifouling hull coating material and preparation method thereof

The invention discloses an aging-resistant antifouling hull coating material, which is an organic silicon resin composite material and is prepared from the following raw materials in parts by weight: 100 parts of organopolysiloxane, 20-50 parts of dimethicone, 2-500 parts of a filler, 1-30 parts of a cross-linking agent, 1-20 parts of a coupling agent, 0.1-10 parts of a catalyst, 30-50 parts of a solvent and 0-5 parts of an additive. The coating material is good in adhesive force, is free of drop through an adhesion promoter, causes small pollution to water body, is good in mechanical property and high in rot resistance, has relatively good hydrophobicity and can play a good antifouling role. 本发明公开了种耐老化防污性船体涂层材料，所述涂层材料为有机硅树脂复合材料，由包括如下重量份的原料制成：有机聚硅氧烷100份，二甲基硅油20-50份，填料2-500份，交联剂1-30份，偶联剂1-20份，催化剂0.1-10份，溶剂30-50份，添加剂0-5份。该涂层材料附着力好，通过加入附着力促进剂做到无脱落，对水体的污染小；力学性能好，防腐性强，具有较好的疏水性，可以起到良好的防污作用。
