摘　　要：以炭系导电材料为填料,制备出了一种适合接地网用导电防腐涂料。研究采用单因素方法确定环氧树脂与多壁碳纳米管的最佳配比、偶联剂、稀释剂的种类、用量以及添加方式,通过分析各个因素对涂料导电性、附着力、表观质量、微观结构的影响,确定了本导电体系的最佳工艺条件为:碳纳米管/环氧树脂质量百分比为22%,稀释剂与环氧树脂的最佳比例为2.3:1,碳纳米管采用硅烷偶联剂KH550浸渍处理之后加入基体中。制得的防腐导电涂料表面光滑无裂纹,体积电阻率为7.2Ω·cm,附着力为1级,达到接地网系统使用要求。New conductive and anti-corrosion coating which is suitable for grounding grid with a carbon-based conductive filler is investigated. This research ensures the optimum ratio of carbon nano tube and epoxy resin, types of coupling agent, and dosage and way for adding with single factors method, determines this conductive system of best process conditions through all affection factors on electrode conductivity, adhesion, and views of surface quality,mierostructure： carbon nano tube/epoxy quality percentage for 22%, diluted agent and resin of best proportions for 2.3：1, carbon nano tube is added into the coatings before dipped with Silane coupling agent KH550. Anti-corrosion conductive paint surface is smooth and free of cracks, the volume resistance rate is 7.2 12. cm, adhesion to level 1, which satisfies the application requirements for grounding grid system.
