摘　　要：在硅烷改性聚醚(MS)聚合物中添加不同比例(10%、25%、40%、50%、60%、75%和100%)的环氧树脂(E-51)及固化剂,制备出一系列E-51改性MS双组分弹性胶粘剂,并利用万能材料试验机对固化产物进行性能测试。结果表明,当E-51添加量为50g(100 g硅烷改性聚醚中的加入量)时,E-51/MS弹性胶粘剂固化后的力学强度达到相对最大值,硬度为50A、拉伸强度为5.5 MPa、断裂伸长率为410%、剪切强度为6.0 MPa和剥离强度为7.4 N/mm。且选用分子质量更大的E-44(环氧树脂)制得的E-44/MS胶粘剂的力学性能和粘接性能更优异。In this paper, adding the epoxy resin E-51 with different proportions （10%, 25%, 40%, 50%, 60%, 75% and100%） and curing agent into the silane-modified polyether （MS） polymer, a series of epoxy resin modified MS twocomponentelastic adhesives were prepared and the properties of their cured products were tested by using a universalmaterial testing machine. The results showed that when the 50 phrs of epoxy resin were added into silane-modifiedpolyether, the mechanical strength of the cured of epoxy resin/MS elastic adhesive reached a maximum, its hardness was 50A, its tensile strength was 5.5 MPa, and its elongation at break was 410%. The shear strength was 6.0 MPa and the peelstrength was 7.4 N/mm. Moreover, the epoxy resin/MS adhesive prepared by using epoxy resin E-44 with a highermolecular weight had better mechanical properties and bonding properties.
