| 摘 要： | 本文选用硫磺硫化体系，用动态硫化法制备ＰＶＣ／ＮＢＲ共混型热性弹性体（ＴＰＥ），该材料具有强度高、永久变形小和可重复加工等特点。考查了共混时间、交联剂含量等因素对材料力学性能及共混比对流变性能的影响。通过透射电子显微镜观察，ＰＶＣ／ＮＢＲ共混物呈现出明显的两相结构。交联的ＮＢＲ为分散相，分散于ＰＶＣ连续相中。动态硫化ＰＶＣ／ＮＢＲ共混型热塑性弹性体在压缩永久形变、扯断永久变形、耐油及耐老化等主要性能上均优于简单机械共混物。

| Abstract: | Use sulphur(s)as curing agent of the poly (vinyl chloride) (PVC)/nitrile rubber(NBR)blends, thermoplastic elastomer (TPE)is preparred from PVC and NBR by dynamic vulcanization.The materials have excellent mechanical properties such as high strength, low tension set, better dimensional stability at high temperature fabricability as thermoplastics.The effects of the blend ratio amount of curing agents to the mechanical properties, to behavior were studied.Under observation of transmisson electron microcopy (TEM),PVC/NBR blends present of distinct two phase structure,the crosslinked NBR particles are dispersed in the marix of PVC.Dynamivulcanization PVC/NBR blends thermoplastic elastomer is superior to unvulcanization blends in compression permanent set ,resistance to oil and to heat. |
