摘　　要：以溶液聚合法合成了有机硅改性丙烯酸树脂,选择不同种类的硅单体进行实验,研究了硅单体用量对涂膜吸水率的影响以及不同软硬丙烯酸类单体比例对涂膜柔韧性及吸水率的影响,并对涂膜进行了红外分析和扫描电镜分析。结果表明:由接枝反应改性的有机硅丙烯酸酯涂料具有优良的性能。Silicone modified acrylic acid resin was synthesized by solution polymerization.By choosing different types of silicon monomers for experiments,the influences of silicon monomer dosage on water-absorption of coating film and different proportion of acrylic acid monomers on flexibility and water-absorption of coating film were studied.The coating film was analyzed by IR and SEM.The result showed that silicone acrylate coatings modified by graft reaction did have excellent properties.
