在"2025先进尼龙产业创新与应用开发大会"上， 烟台新特路新材料科技有限公司总经理 蔡智奇博士 分享了" 高温工程塑料耐候老化的机理与解决方案 "的前沿技术。 蔡智奇博士开篇即聚焦尼龙材料老化的核心问题。他指出， 尼龙的老化源于内因与外因的双重作用 ： 关键机理： 内因：尼龙的 酰胺键结构及烷基链 在热、光、氧、水等环境下易引发自由基反应，导致分子 链断裂和黄变； 外因：紫外线辐射、高温加工、湿热环境等加速材料降解，尤其在新能源汽车、户外工程等场 景中表现显著。 热氧老化：自由基链式反应 生成过氧化物 ，引发断链与力学性能下降； 光降解：紫外光（290-325nm波段）触发尼龙敏感基团的 夺氢反应 ； 水解催化： 水分子加速酰胺键的可逆断裂 ，降低材料寿命。 蔡博士强调：" 阻隔热源、隔绝氧气、消除自由基 是延缓尼龙老化的核心思路，而助剂的作用正是 从分子层面阻断这些反应链。" 【DT新材料】 获悉，尼龙（聚酰胺）作为五大工程塑料之一，凭借高强度、耐磨性、耐化学腐蚀等 特性，广泛应用于汽车、电子、纺织、新能源等领域 。 随着产业升级， 高温、高湿、强紫外线等极 端环境对尼龙材料的耐候性提出了更高要求。 然而 ...
