摘　　要：目的:研究分步固化ZY-1、ZY-2赝复硅橡胶对两者之间粘合强度的影响。方法:将ZY-1、ZY-2硅橡胶80℃恒温下进行分步固化,将硅橡胶粘结剂Adhesive A作为阳性对照组。测定各小组中ZY-1和ZY-2之间的粘合强度,并进行统计学分析,对两种硅橡胶的粘接面进行扫描电镜观察。结果:实验组ZY-1和ZY-2硅橡胶之间的粘合强度与阳性对照组相比无显著性差异;扫描电镜观察两层材料之间没有缝隙,形成了良好的界面结合。结论:分步固化ZY-1和ZY-2硅橡胶可以获得较为理想的粘合强度,在保证每层硅橡胶不发生形变的前提下以分步固化时间间隔为15 min时其粘合性能最佳。Objective： study the influence of step by step solidification to ZY-1,ZY-2 type of silicone rubbers＇ adhesive strength. Method： Under Constant temperature 80 ℃. The group of Silicone rubber adhesive （Adhesive A） was used for Positive control group. The adhesive strength of different teams between ZY-1 and ZY-2 was measured and Statistical anal- ysis was done. The Bonding interface of Silicone rubber was observed by scanning electron microscope. Result： there are no significant differences between direct experimental group and positive control group. Scanning electron microscope found that the two materials formed a good interracial bonding and had no gap. Conclusion： ensuring each layer of silicone didn＇t occur deformation, step by step solidification to ZY-1,ZY-2 silicone rubbers at 15-minute can get a better adhesion.
