Abstract: Multifunctional polymer coatings is one of the important research directions ofmarine coatings. In this paper，the epoxy resin modified by silicone oil was prepared byphysical blending method，which had the function of anti-corrosion，anti-pollution and anti-drag. The adhesion，contact angle，peer strength，drag reduction and diatom adhesionresistance of the coating were tested. The results showed that the epoxy coating modified by silicone oil had good adhesion on the surface of aluminum alloy substrate，and the grading was 0. The surface was hydrophobic，the water contact angle reached 103. 49°，and the peer strength of the adhesive tape was only 0. 002 N/cm，which was significantly lower than beforemodification. It had inhibition effect on diatom attachment，and the inhibition rate reached 70%. At the same time，the friction resistance with the water flow was reduced. The hydrophobicity，antifouling and drag reduction of the epoxy coating were improved by addingdimethyl silicone oil to the epoxy resin for physical blending modification.

摘要： 多功能性聚合物涂层是船舶涂料研究的重要方向之一。采用物理共混改性的方法，利用硅油改性环氧树脂，制备具有防腐防污减阻多功能的涂层。测试了涂层的附着力、接触角、剥离强度、减阻性能和抗硅藻附着性能。结果表明：硅油改性环氧涂层在铝合金基材表面附着良好，划格评级为 0级。表面具有疏水性，水接触角达到 103. 49°，胶粘带剥离强度为 0. 002 N/cm，比改性前显著降低，对硅藻附着具有抑制作用，抑制率达到 70%，同时降低了与水流的摩擦阻力，100 r/min转速下，旋转扭矩值降低了 4. 27%。加入二甲基硅油对环氧树脂进行物理共混改性，在保持了涂层对基材良好附着的情况下，有效提高了环氧涂层的疏水性、防污性和减阻性。
