Abstract
本发明公开了一种用于盐碱土地输电线路的防腐涂料及其应用，属于输电线路防腐技术领域，包括如下原料：环氧树脂、水性聚氨酯、改性氧化石墨分散液、空心玻璃微珠、固化剂，本发明针对盐碱地区高盐分、高湿度、强腐蚀环境对输电线路造成的严重电化学腐蚀问题，尤其是常规防腐措施易失效、设施寿命缩短及运维成本高等挑战，本发明通过多组分协同作用实现系统性防腐：采用改性氧化石墨构建纳米级屏障延长腐蚀介质扩散路径，ZnO‑TiO2核壳结构纳米粒子兼具物理屏障与化学缓蚀双重抑制腐蚀；相较于传统方法，该技术通过优化材料实现阻隔性能与分散性的动态平衡，显著提升输电线路在盐碱土地中的耐腐蚀性、环境适应性和长期稳定性。
