摘　　要： 研制了一种以丙烯酸酯类树脂为基料的改性碳纤维体系导电涂料。用单因素方法确定改性碳纤维/树脂质量比,偶联剂的种类、用量以及添加方式、涂料的固化工艺等方面对涂料电性能的影响关系,然后用正交实验进一步优化各因素对涂膜导电性能的影响,确定了制备碳纤维体系导电涂料的最佳工艺条件为:改性碳纤维/树脂质量比为0.7,钛酸酯偶联剂TMC-102采用预处理用量为1%(wt,下同)和直接加入用量为1.5%相结合,制得的导电涂料综合性能较好;固化温度为50℃下固化20min,涂膜厚度为150μm时,其表面电阻率达到1.02Ω/sq。 A composite conductive paint based on modified carbon fibers and acrylic resin was prepared. Effect of the ratios fillers and resin, coupling agents and curing technology on the properties of the paint were discussed using single factor method. And the main influencing factors in preparation paint were studied with an orthogonal design of experiment, and the optimal technology conditions were the ratio of the fillers and resin 0.7, the weight fraction of coupling agent 2.5%, where containing pretreatment dosage 1% and directly adding dosage 1.5wt%. And the surface resistance of the film, the thickness was 150μm, reached to 1.02Ω/sq. when the film was cured 20min under 50℃.
