摘要:以氨基硅油为原料，通过开环加成改性了甲基丙烯酸缩水甘油酯(GMA)，再与甲基丙烯酸甲酯(MMA)、丙烯酸正丁酯(BA)单体通过自由基共聚，合成了具备水解特性和低表面能特性的氨基硅油改性丙烯酸树脂。采用红外光谱（FT-IR）、核磁共振谱图（1H-NMR）对树脂结构进行了表征，证实了氨基硅油参与了接枝反应及树脂的聚合，并对树脂进行接触角、黏度、涂膜性能及热性能分析。结果表明：1%(质量分数）的氨基硅油的引入使水接触角达到91.5°，漆膜的表面能降低到28.26 mN·m-1；树脂的黏度随氨基硅油含量的增加而降低，涂膜的柔韧性、耐冲击强度随之增大；但漆膜的表面形态没有发生明显变化，非结晶度变化规律表现一致。此外，改性后树脂的玻璃化转变温度变化不明显，但热稳定性增强。所制备的氨基硅油改性丙烯酸树脂作为一种低表面能有机硅改性树脂在海洋防污领域有潜在的应用价值。

Abstract:Amino silicone oil modified acrylic resin with hydrolysis characteristics and low surface energy characteristics was synthesized by free radical copolymerization with glycidyl methacrylate (GMA) modified by amino silicone oil with methyl methacrylate (MMA) and butyl acrylate(BA). The structure of the resin was characterized by FT-IR and 1H-NMR, which confirm the amino silicone oil was involved in the graft reaction and the polymerization of the resin, and the contact angle, viscosity, coating performance, and the thermal performance were analyzed. The results showed that the introduction of 1% amino silicone oil made water contact angle 91.5°, and the surface of the film can be reduced to 28.26 mN·m-1; the viscosity of the resin decreased with the increase of the content of amino silicone oil; film flexibility, impact strength increased. But there is no obvious change in the surface morphology of the film, and the consistent change of the noncrystallinity. In addition, the glass transition temperature of the modified resin was not obvious, and the thermal stability was enhanced. Amino silicone oil modified acrylic resin as a kind of low surface energy silicone modified resin has potential application value in the field of marine anti-fouling.
