环境友好型有机硅改性丙烯酸树脂的合成及其用于海洋防污涂料的性能研究很有意义.以氨基硅油为原料,通过开环加成改性甲基丙烯酸缩水甘油酯(GMA),再与其他丙烯酸单体自由基聚合制备出氨基硅油改性丙烯酸树脂,借助FT-IR对其结构进行了表征,并以改性丙烯酸树脂为防污涂料成膜物制备了兼具自抛光特性／低表面能特性的防污涂料,考察了氨基硅油用量对涂料涂膜的附着力、柔韧性、接触角和表面能等的影响.结果表明:当氨基硅油用量为1％时,涂膜综合性能达到最佳,附着力、柔韧性达到一级,抗冲击强度≥50 kg·cm,硬度达到2H,接触角为99.6°,表面能为23.3 mN/m;结合实海挂板试验显示,改性的防污涂料具有良好的防污性能.
