摘　　要：本文探讨了苯乙烯类热塑性弹性体(SEBS)在汽车行业中作为高效泡沫材料的应用。研究的起因是汽车行业对减轻车辆重量以降低温室气体排放的需求。文章通过实验分析了SEBS对聚丙烯(PP)泡沫配方的影响,以及不同SEBS结构、浓度和滑石粉浓度对泡沫机械性能的影响。研究结果表明,加入SEBS可以增强PP泡沫的抗冲击性和弹性,提高泡沫的柔韧性和降低脆性,即使在减重50%的情况下,SEBS配制的泡沫仍保持良好的机械和结构特性,有助于实现汽车轻量化,减少二氧化碳排放。This article explores the application of styrenic thermoplastic elastomers(SEBS)as efficient foam materials in the automotive industry.The impetus for the study stems from the automotive industry's demand to reduce vehicle weight in order to lower greenhouse gas emissions.The article experimentally analyzes the impact of SEBS on polypropylene(PP)foam formulations,as well as the effects of different SEBS structures,concentrations,and talc powder concentrations on the mechanical properties of the foam.The research findings indicate that the addition of SEBS can enhance the impact resistance and elasticity of PP foam,improve the flexibility of the foam and reduce its brittleness.Even with a 50%reduction in weight,the foam formulated with SEBS maintains good mechanical and structural properties,contributing to the realization of automotive lightweighting and the reduction of carbon dioxide emissions.
