摘要

随着新能源汽车的发展，对满足更高标准的汽车内饰材料的需求越来越大。在这种情况下，热塑性弹性体（TPE）作为一种完全可回收的环保高分子材料，与聚氯乙烯（PVC）、聚氨酯（PU）和热塑性聚烯烃（TPO）蒙皮相比，具有不含增塑剂和溶剂、机械性能优异、挥发性有机化合物（VOC）释放少、加工成本低等优点，成为汽车注塑汽车蒙皮的理想选择。因此，本研究考察了氢化苯乙烯-丁二烯-苯乙烯嵌段共聚物（SEBS）分子量、化学结构和聚丙烯（PP）掺杂量对TPE热力学、结晶度、流变学和力学性能的影响，为指导TPE注塑蒙皮的材料选择提供科学依据。

Effect of Composition on Processing and Mechanical Properties of TPE for Injection Molding Automotive Skin

With the development of new energy vehicles, there is a growing demand for automotive interior materials that meet higher standards. In this case, thermoplastic elastomer (TPE), being a completely recyclable environment-friendly polymer material, possesses advantages such as plasticizers and solvents free, excellent mechanical properties, less volatile organic compounds (VOC) release and low processing cost compared with polyvinyl chloride (PVC), polyurethane (PU), and thermoplastic polyolefin (TPO) skins, become a desirable choice for automotive injection molding automotive skin. Hence, this work investigates the influence of hydrogenated styrene-butadiene-styrene block copolymer (SEBS) molecular weight, chemical structure, and polypropylene (PP) doping amount on thermodynamic, crystallinity, rheological, and mechanical properties of TPE, which provides a scientific basis for guiding the material selection of TPE injection molding skin.
