| 摘 要： | 通过密炼共混法成功制备了聚乙烯（PE）/废旧三元乙丙橡胶（EPDM）胶粉的热塑性弹性体,研究了不同PE/EPDM共混比和不同相容剂对热塑性弹性体力学性能的影响。实验结果表明：随PE用量增加,拉伸强度、100%定伸应力、硬度提高,拉断伸长率降低。在PE用量不变的条件下,加入相容剂可改善PE/废旧EPDM胶粉热塑性弹性体的基本力学性能,其中随着相容剂氯化聚乙烯（CPE）与马来酸酐接枝苯乙烯-乙烯-丁二烯-苯乙烯嵌段共聚物（SEBS-g-MA）用量的增加,拉伸强度、100%定伸应力、拉断伸长率和硬度提高;而以马来酸酐接枝乙丙橡胶（EPDM-g-MA）为相容剂时,除拉断伸长率外,拉伸强度、100%定伸应力与硬度则呈现相反的趋势,其随EPDM-g-MA用量增多而降低。

| Abstract: | A new thermoplastic elastomer（TPE）was prepared by blending PE and waste EPDM rubber powder.The mechanical properties of TPE were tested.The results showed that with the increase of PE content,the tensile strength,modulus at 100%,hardness increased,but the elongation at break decreased.Keeping the content of PE,the compatibilizer can improve the mechanical properties of TPE.With the increase of the compatibilizer,such as CPE and SEBS-g-MA,the tensile strength,100% modulus,elongation at break and hardness increase.With the increase of EPDM-g-MA as compatibilizer,the tensile strength,100% modulus and hardness decrease,but elongation at break increase. |
