摘　　要：为研究不同配比硅橡胶材料在雾霾条件下的电晕老化特性,选择了3类不同配比硅橡胶材料,采用静态接触角、扫描电镜、傅里叶红外光谱等方法对硅橡胶材料进行老化特征测试.研究结果表明,3类不同配比硅橡胶材料在雾霾条件下的电晕老化特性差异较大,其中硅橡胶主体的质量分数低、氢氧化铝质量分数高的A类材料电晕老化特性相对较优异,表现为表面微观形貌较好,附着物也更少,亲水性基团能够以较快的速度向材料内部迁移,恢复速率最快.但此类材料憎水性丧失较为严重,同时老化后此类材料中的Si—O—Si基团与Si—CH_(3)基团的特征峰面积相对较大,主链和侧链保存更加完整,化学结构破坏最小.In order to study the corona aging characteristics of silicone rubber materials with different proportions under haze conditions,three types of silicone rubber materials with different proportions were selected,and the aging characteristics were tested by the static contact angle,scanning electron microscope,and Fourier transform infrared spectrum.The results show that the corona aging characteristics of the three types of silicone rubber materials with different ratios under haze conditions are quite different.Among them,the corona aging characteristics of the A-type materials with low silica gel content and high aluminum hydroxide content is relatively excellent,which are manifested in better surface morphology and fewer attachments.The hydrophilic groups can migrate to the interior of the material at a faster speed,so the recovery rate is the fastest,but the hydrophobicity loss of such materials is relatively serious.At the same time,the characteristic peak areas of the Si—O—Si group and Si—CH_(3) group in such ma⁃terials after aging are relatively large,the main chain and side chain are more complete,and the chemical structure damage is the smallest.
