摘　　要：高寒高海拔地区水工混凝土处于冻融循环和紫外辐照等严苛服役环境下,易发生材料老化乃至结构失效问题。环氧树脂涂层是提升混凝土耐久性和安全性的常用技术手段,但在严苛条件下也面临耐老化性能不足、提前失效的风险。本研究重点阐述了高寒高海拔地区环氧树脂涂层耐老化性能研究现状,总结了环氧树脂耐老化性能提升方法,分析了添加耐老化助剂、有机硅改性、纳米粒子改性等常用方法的特点和不足。本研究可为后续高寒高海拔环境下高性能高耐久环氧树脂涂层的研发提供参考。Hydraulic concrete in alpine cold and high-altitude areas is subject to severe service environments such as freeze-thaw cycles and ultraviolet irradiation,and is prone to material aging and even structural failure.Epoxy resin coating is a typically used technology to improve the durability and safety of concrete,but it also faces the risk of insufficient aging resistance and early failure under severe conditions.This paper focuses on the current status of research on the aging resistance of epoxy resin coatings in alpine cold and high altitude regions,summarizes the methods to improve the aging resistance of epoxy resin,and analyzes the characteristics and shortcomings of the typically used methods,such as the addition of aging-resistant additives,organosilicon modification and nanoparticle modification.This paper can provide a reference for the subsequent research and development of high-performance and high-durability epoxy resin coatings in alpine cold and high-altitude environments.
