摘要

随着报废汽车数量的增加，汽车塑料的回收和高附加值再利用引起了全球的关注。本文采用两级高压静电分离法对PP、ABS和PVC的乘用车塑料混合物进行了分选。聚丙烯、ABS和聚氯乙烯的纯度均高于97%，回收率分别为55%、93%和48%。以聚丙烯塑料为例，研究了再生材料的力学性能以及再生材料与新材料的不同配比。结果表明，采用7:3比例的新材料和再生材料再生的轿车保险杠能够满足性能要求。该发现为其他汽车塑料的高附加值再利用提供了参考。

High-voltage Electrostatic Separation and Equivalent Reuse of Plastics Used in Passenger Vehicle

The recycling and high-valued added reuse of automotive plastics have elicited global attention as the number of end-of-life vehicles increase. In the paper, the two-stage high-voltage electrostatic separation is used to explore the sorting of passenger vehicle plastic mixtures of PP, ABS and PVC. The purities of PP, ABS and PVC are all higher than 97%, and the recovery rates are 55%, 93%, and 48%, respectively. Taking PP plastic as an example, the mechanical properties of the recycled materials and the different ratios of recycled and new material mixtures are studied. Results show that the passenger car bumpers reproduced with a 7:3 ratio of new and recycled materials can satisfy the performance requirements. The finding provides a reference for the high additional value reuse of other automotive plastics.
