摘　　要：以聚丙烯(PP)类材料分别与生物基三元乙丙橡胶(Bio-EPDM)和石油基三元乙丙橡胶(EPDM)熔融共混后制备热塑性弹性体类(TPO)汽车内饰表皮,并经过高能电子束进行交联处理,分析了不同EPDM种类的汽车内饰表皮经电子交联处理后相关性能的变化。结果表明:Bio-EPDM在电子交联后机械性能会有所提高,而EPDM表皮在电子交联后机械性能会降低;交联后的表皮材料熔融黏度升高,有利于汽车内饰花纹的保持;电子交联会提高内饰表皮的阻燃性能、热稳定性,但会会恶化内饰表皮气味,使用前需要进行低气味处理。This article presents the preparation of thermoplastic elastomer(TPO)automotive interior skins by melt blending polypropylene(PP)materials with bio based EPDM and petroleum based EPDM respectively.High energy electron beam crosslinking treatment was applied to the interior skin of automobiles,and the changes in related properties of different types of EPDM interior skin after electron crosslinking treatment were analyzed.The results showed that the mechanical properties of Bio EPDM were improved after electronic crosslinking,while the mechanical properties of EPDM skin were reduced after electronic crosslinking;The melting viscosity of the cross-linked skin material increases,which is beneficial for maintaining the pattern of the car interior;Electronic crosslinking can improve the flame retardancy and thermal stability of the interior surface,but it will worsen the odor of the interior skin,and low odor treatment is required before use.
