摘　　要：基于乙酸乙烯酯-乙烯(VAE)共聚乳液以及聚丙烯酸酯两种乳液各自的特性,本文用乙烯基类单体对VAE乳液进行接枝改性,形成了具有以VAE为主链,丙烯酸酯聚合物为支链的接枝共聚物,获得了性能优良的皮革涂饰材料。通过在牛皮鞋面革上的涂饰应用证实,该涂饰材料具有良好的耐水性、耐溶剂、耐干湿擦性,且涂层粒面细致、真皮感佳,是一种具有良好应用前景的皮革涂饰材料。This study concerns the characteristic of the Vinyl acetzte/ ethylene copolymer （VAE） and acrylate emulsion. The graft copolymerization of VAE with acrylate monomer was investigated using potassium persulphate as an initiator by free radical polymerization. backbone and the avrylate polymerizate was branched chain, Which the VAE polymerizate was the leather Finishing agent with cladodification structure was prepared. From cow leather shoes upper application experimentation,the result suggested that the emulsion could be used as leather Finishing. When the modification VAE emulsion is used as the leather Finishing, which is related to the flexibility,the water resistance,the solvent resistance,the xerotripsis/ moist frictio resistance, grain surface particularity and good handle, the compatibility and low glasstransition temperature of the EVA, is an important leather finishing material.
