摘　　要：硅橡胶电缆经常发生印字污染,影响使用。大气压等离子体表面改性技术广泛用于材料表面性能提升,但解决印字污染问题的相关条件、方法和效果等尚需研究。本工作利用高频交流电源驱动空气电弧射流对硅橡胶进行表面改性,通过发光图像、电学特性和光谱谱线强度表征射流的放电特性,并通过热成像仪获得射流处理下硅橡胶表面温升情况。模拟实际处理工艺,以不同移动速率处理硅橡胶表面。结果表明,射流处理能够有效解决硅橡胶表面印字污染问题,同时使硅橡胶表面的水接触角下降。在低速处理条件下,由于电弧的烧蚀作用,闪络电压和击穿场强均会降低。扫描电子显微镜(SEM)和X射线能谱仪(EDS)检测结果表明,处理后的硅橡胶表面交联聚合程度提高,抑制硅橡胶界面分子的扩散运动,从而提高了其抗印字污染性能。Silicone rubber cables often suffer from printing pollution,which affects their usage.Atmospheric pressure plasma surface modification technology is widely used to improve material surface properties,but corresponding conditions,methods,and effects for solving printing pollution problems still need to be researched.In the paper,the surface of silicone rubber was modified by air arc jet generated by a high-frequency AC power supply.Discharge characteristics of the arc were characterized by luminous images,electrical properties,and spectral line intensity.Surface temperature rise of silicone rubber after the discharge was obtained by a thermography.Dynamic treatment of silicone rubber surface at different speeds was simulated in actual processing conditions.The results indicated that arc treatment could effectively solve printing pollution problem on the surface of silicone rubber,reduce water contact angle of silicone rubber surface at the same time.Under low-speed treatment conditions,surface breakdown voltage and breakdown voltage decreased due to the erosion effect of the arc.SEM and EDS detection results implied that crosslinking degree of silicone rubber surface increased after the treatment,which inhibited molecular diffusion movement at silicone rubber interface and thus improved its resistance to printing pollution.
