摘要
目的:研究分步固化ZY1和ZY2赝复硅橡胶的耐老化性能。方法:在分步固化ZY1和ZY2硅橡胶基础之上,经老化试验后测定其粘合强度,利用两层硅橡胶之间涂布Adhesive A作为阳性对照组,评价分步固化ZY1和ZY2硅橡胶的耐老化性能,并进行统计学分析。结果:实验组和阳性对照组老化后的粘合强度均较老化前有所下降,但破坏方式仍然是内聚破坏;实验组老化后粘合强度变化百分率绝对值低于阳性对照组。结论:ZY1和ZY2硅橡胶经分步固化后仍具有良好的耐老化性能。
Objective：To evaluate the aging resistance of ZY1 and ZY2 silicone elastomers with step-cu-ring.Method：The adhesive strength of ZY1 and ZY2 silicone elastomers with step-curing was tested by aging test .And the Adhesive A was coated between two layers of silicone elastomers which was been as positive control group, the aging resistance was evaluated and carried on the statistical analysis in ZY1 and ZY2 silicone elasto-mers with step-curing.Results：The adhesive strength of both the experimental group and positive control group were decreased after hot oxygen aging and ozone aging, but the failure mode was still cohesive failure.The abso-lute value of of percentage change in the experimental group after hot oxygen aging and ozone aging was lower than the positive control group.Conclusion：ZY1 and ZY2 silicone elastomers with step-curing possessed good ag-ing-resistance.
