摘要
Abstract
In this study,a series of recycled polyamide 6(PA6)materials was developed by blending virgin PA6(V-PA6)with varying proportions of post-consumer recycled PA6(PCR-PA6).The mechanical properties(tensile,flexur-al,impact)and thermal stability of the blends were systematically investigated as a function of the PCR-PA6 content.Results indicated a gradual decline in these properties with increasing PCR-PA6 loading.However,when the PCR-PA6 content was lower than 20 wt%,the blends retained more than 90%of their strength and plasticity,meeting the perfor-mance criteria for automotive plastics.To validate practical application,a deflector bracket was successfully injection-molded using the 20 wt%PCR-PA6 formulation.The component passed critical automotive qualification tests,includ-ing low-temperature impact resistance,thermal cycling,and light aging.Furthermore,a 7 500 km loaded road test con-firmed the bracket's durability,with no observable changes in appearance or structure,demonstrating a service life com-patible with vehicle requirements.关键词
