摘　　要：随着复合绝缘子的广泛应用,其退役数量逐年增加,累积堆置占用大量土地和空间资源,危及生态环境安全,目前尚未有有效回收利用途径。通过分析绝缘子伞裙护套硅橡胶的材料组成及特点,分析橡胶粉用于沥青改性的技术可行性,以及橡胶沥青市场的需求情况,提出废旧绝缘子硅橡胶制粉用于生产橡胶沥青。硅胶粉在沥青中发生溶胀、扩散和分散,互相黏连形成网络结构,形成两相连续结构共混体系,提高沥青的黏度,可改善沥青路面的性能。所提方案可消纳全部退役复合绝缘子硅橡胶,并有效缓解我国公路建设对橡胶粉需求的紧张现状。With the wide application of composite insulators,the number of retired insulators increases year by year.The accumulative stacking occupies a large amount of land and space resources,which endangers the safety of ecological environment.By analyzing the material composition and characteristics of silicone rubber for insulator umbrella skirt sheath, the technical feasibility of rubber powder used in asphalt modification and the demand of rubber asphalt market are analyzed.The waste insulator silicone rubber powder used to produce rubber asphalt is put forward.Silica gel powder in asphalt swelling,diffusion and dispersion,each other adhesion to form a network structure,forming a two-phase continuous structure blending system,improve the viscosity of asphalt,can improve the performance of asphalt pavement.The proposed scheme can absorb all retired composite insulator silicone rubber and effectively relieve the demand of rubber powder for highway construction in China.
