摘　　要：通过斜面法试验研究了不同三水氧化铝(ATH)含量对硅橡胶材料耐漏电起痕和烧蚀性能的影响。借助TG、SEM等近代仪器分析技术,研究了ATH的阻燃机理及其在硅橡胶中的分散性。试验结果表明提高ATH的含量能增加硅橡胶材料的耐漏电起痕性能,但同时也将降低其机械性能。Through slope method, the influence of different aluminium trihydrpoxide（ATH） content upon current leakage tracking and ablation resistant performance of silicone rubber material has been tested and studied. By means of analytical technology using modern instruments, such as TG and SEM etc., the fire-retardant mechanism and dispersivity in silicone rubber have been studied. Results of test show that the increase of ATH content can increase the current leakage tracking resistant performance of silicone rubber material, but, at the same time, its mechanical performance will also be decreased.
