The azodicarbonamide (AC) and aluminum hydroxide (ATH) were used to discuss the effect of their combination on the anti-tracking performance, mechanical properties, and hydrophobicity of silicone rubber composites. The possible reasons for AC and ATH synergistically improving the tracking resistance of the composites were discussed through scanning electron microscopy, contact angle, and other characterization methods. The results show that when the ATH is filled only, the filling amount must reach 100 phr, and the anti-tracking performance of silicone rubber composite can achieve grade 1A4.5. However, when the filling amount of AC and ATH are 3 phr and 80 phr respectively, with the help of the arc extinguishing and gas phase flame retardant effect of a large amount of nitrogen and carbon monoxide generated by the decomposition of AC, the anti-tracking performance of the silicone rubber composite also can achieve grade 1A4.5, and compared with the composite filled with pure ATH, it has better tensile strength and hydrophobicity, which is expected to be applied in the field of composite insulators.
