摘要 研究了不同温度下聚氯乙烯(PVC)的短期蠕变和应力松弛行为,应用时-温等效原理,将不同温度下的蠕变/应力松弛曲线平移得到参考温度85℃下的黏弹性主曲线,获得PVC的长期黏弹性能. Short-term creep and stress relaxation of PVC under different temperatures were studied. The master curves of 85 ℃ were obtained using the time-temperature equivalence principle by shifting the creep stress relaxationcurves horizontally,and thus the long-term viscoelasticity of PVC were got.
