| 摘 要： | 研究了SY 2 4B胶膜和SY H2糊状胶粘剂的剪切疲劳和蠕变性能。SY 2 4B胶膜和SY H2糊状胶粘剂同为中温固化的结构胶粘剂 ,SY 2 4B胶膜采用橡胶增韧 ,SY H2糊状胶粘剂采用热塑性树脂增韧。SY 2 4B胶膜虽然具有优异的韧性 ,但SY H2糊状胶粘剂的剪切疲劳和蠕变性能优于SY 2 4B胶膜 ,这与增韧剂种类与胶层厚度有一定关系。温度、应力和时间也是影响蠕变量的重要因素

| Abstract: | Shear fatigue and creep properties of SY 24B film adhesive and SY H2 paste adhesive have been studied.SY 24B film adhesive and SY H2 paste adhesive are all moderate temperature curing adhesives.SY 24B film adhesive is toughened by rubber and SY H2 paste adhesive is toughened by thermoplastic resin.SY 24B film adhesive has better toughness than SY H2 paste adhesive,but the latter has better shear fatigue and creep properties.Difference of the two adhesives is relevant with flexibilizer and bondline thickness.Temperature,stress and time are also factors influencing the creep residue deformation. |

| Keywords: | moderate temperature curing adhesive flexibilizer shear fatigue creep |
