摘　　要：以超细全硫化粉末丁腈橡胶(UFPNBR,型号VP-401、VP-501、VP-550)与HPVC为原料制备HPVC/UFPNBR全硫化热塑性弹性体,研究了橡塑比对热塑性弹性体的力学性能、流变性能、耐油性能及耐增塑剂迁移性能的影响。结果表明,随着橡塑比的增加,热塑性弹性体的拉伸强度先增加后降低;断裂伸长率和断裂永久变形逐渐降低;橡塑比的增加有利于共混物的塑化,但降低了共混物的加工性能;UFPNBR的加入能有效地抑制增塑剂的析出,提高了热塑性弹性体的耐油性能及耐增塑剂迁移性能。Fully cured HPVC/UFPNBR thermoplastic elastomer was prepared by using fully cured ultrafine powdered acrylonitrile-butadiene rubber(UFPNBR,VP-401,VP-501 and VP-550) and HPVC as raw materials.Influences of the ratio of rubber to plastics on the mechanical properties,rheological properties,oil resistance and plasticizer migration resistance of the thermoplastic elastomer were studied.The results showed that::①with the increase of rubber/plastics ratio,the tensile strength of thermoplastic elastomer increased ...
