Abstract：
Increasing recycled plastic content in cars to 25% by 2030 is one of the key measures for decarbonizing the automotive industry defined by the European Commission. This should include the recovery of plastics from end-of-life vehicles (ELVs), but such materials are hardly used in compounds today. To close the knowledge gap, two ELV recyclate grades largely based on bumper recycling were analyzed in comparison to a packaging-based post-consumer recyclate (PCR). The composition data were used to design polypropylene (PP) compounds for automotive applications with virgin base material and mineral reinforcement, which were characterized in relation to a commercial virgin-based compound. A compound with a 40 wt.-% ELV-based bumper recyclate can exceed one with just a 25 wt.-% packaging-based recyclate in terms of stiffness/impact balance. While the virgin reference can nearly be matched regarding mechanics, the flowability is not reached by any of the PCR compounds, making further development work necessary.
摘要：
到2030年，将汽车中的再生塑料含量提高到25％是欧盟委员会定义的汽车工业脱碳的关键措施之一。这应包括从报废车辆（ELV）中回收塑料，但是这种材料在今天几乎不用于化合物中。为了缩小知识差距，与基于包装的消费后回收物(PCR)相比,分析了两种主要基于保险杠回收的ELV回收物等级.组成数据用于设计具有原始基础材料和矿物增强材料的汽车应用聚丙烯（PP）化合物，其特征在于与商业上基于处女的化合物有关。化合物的重量为40。-%基于ELV的保险杠回收物可以超过仅25wt。-在刚度/冲击平衡方面的基于包装的回收物%。虽然处女参考在力学方面几乎可以匹配，任何PCR化合物都无法达到流动性，需要进一步的发展工作。
