摘　　要：采用两步合成法制备得到环氧接枝丙烯酸复合乳液,该工艺克服了2种树脂接枝率低、储存稳定性差以及反应过程中有机溶剂污染等问题。确定了工艺的最佳反应条件,并对酯化产物、接枝共聚产物进行了FT-IR和1 H NMR分析。盐雾老化实验发现所合成的复合乳液涂膜的耐腐蚀性能优异,DMA分析显示涂膜具有较高的损耗系数和较宽的阻尼温域,表明涂膜有良好的阻尼性能。Epoxy grafted acrylate composite latex is prepared by using two step synthesis method. The process not only solves the problem of organic solvents pollution, but also increases the graft ratio and improves simultaneously the storage stability. The optimum conditions of the reactive process are determined. The chemical structures of esterification product and epoxy acrylic graft copolymer are proved by FT -IR and ^1 H NMR. The salt spray test indicates that the coating presents a perfect corrosion resistance. The dynamic mechanical analysis （DMA） shows that the films of composite latex have high loss coefficient value and broad temperature range. It is implied that the composite material possesses good damping property.
