摘　　要：对阻燃改性尼龙66的长期热老化性能进行了系统性研究。通过对比有卤阻燃体系、有卤阻燃不同稳定剂体系和无卤阻燃体系,通过不同的老化条件评估了铜盐稳定剂对材料热稳定性的影响。结果显示,铜盐稳定剂的加入显著提高了尼龙66的热稳定性,对拉伸强度、弯曲模量和冲击强度等力学性能具有一定程度的保护作用。旨在为开发具有高热稳定性的尼龙66材料提供了理论依据和实践指导。This paper systematically studied the long-term thermal aging properties of flame-retardant modified nylon 66.By comparing halogen-containing flame-retardant systems,halogen-containing flame-retardant systems with different stabilizer systems,and halogen-free flame-retardant systems,the influence of copper salt stabilizers on the thermal stability of the material was evaluated through different aging conditions.The results showed that the addition of copper salt stabilizers significantly improved the thermal stability of nylon 66,providing a certain degree of protection to the material's tensile strength,bending modulus,and impact strength.This study aims to provide theoretical basis and practical guidance for the development of nylon 66materials with high thermal stability.
