摘　　要：汽车保险杠多采用热塑性聚烯烃弹性体材料,具有较高的回收价值。保险杠表面的油漆涂层与基体相容性差,对保险杠材料的回收利用会产生影响。通过傅里叶变换红外光谱、元素、力学性能、热重等分析测试,采用宏观、微观相结合的分析方法研究了油漆对汽车保险杠回收料的热氧老化、力学性能和微观组织形态的影响规律。结果表明,油漆的残留会降低回收料的力学性能,尤其对韧性有较大损害,同时使回收料的力学性能稳定性下降,需要通过合适的方法去除退役汽车保险杠表面的油漆。The automobile bumper is mostly made of thermoplastic polyolefin elastomers（TPO） materials,which has high recycling value. Paints on the bumper surface influence the bumper material recycling because of the poor compatibility with base material. Based on Fourier infrared spectrum analysis,elements analysis,mechanical properties,thermogravimetric analysis,the effects of paints on the thermo-oxidative degradation,mechanical properties and microstructure morphology of automobile bumper recycling material were studied adopting the method of macro and micro analysis. The results show that paint residue can reduce the mechanical properties of the recycling,especially has the larger damage to toughness,simultaneously makes the recycling material mechanics stability occurrence to drop,it is needed for removing the paints of the retired bumper by appropriate methods.
