摘　　要：采用分拉法对聚氯乙烯绝缘材料进行了拉伸试验,研究了聚氯乙烯绝缘材料在同一设备、同一操作人员、同一环境和不同拉伸速率下机械性能的变化。结果表明,选择不同的拉伸速率对材料的抗张强度的影响不明显,但对断裂伸长率的影响较大。Tensile tests were carried out on polyvinyl chloride insulating materials by means of the split-tension method,and changes in mechanical properties of polyvinyl chloride insulating materials under the same equipment,the same operator,the same environment and the different stretching rate were investigated.The results showed that tensile strength of materials was not affected obviously by the different stretching rate,but the elongation at break was affected greatly.

关 键 词：机械性能 绝缘材料 拉伸速率 抗张强度 断裂伸长率
