摘要

硅橡胶作为典型的绝缘材料，具有优异的绝缘性能、防污性能和可加工性，在高压输电和电气设备外绝缘方面都应用广泛。随着电子元器件、集成电路、电力输送系统等实际应用的快速发展，对常用于设备绝缘保护的硅橡胶材料的绝缘性能和介电性能也提出了更高的要求。在硅橡胶中掺杂填料，可以有效地提高硅橡胶的相对介电常数和击穿场强。目前常用的填料有高相对介电常数填料、宽带隙填料、碳系填料、金属填料，以及混合填料等。本文总结了提高硅橡胶复合材料介电性能和绝缘性能的相关研究，对硅橡胶复合材料的发展进行了展望。

Abstract

Silicone rubber

widely recognized for its excellent processability and contamination resistance

is extensively utilized in high-voltage transmission and external electrical insulation.Despite its broad applications

silicone rubber's insulation and dielectric properties still require further enhancements.With the rapid development of electronic components

integrated circuits

power transmission systems and other practical applications

the insulation properties and dielectric properties of silicone rubber materials commonly used in equipment insulation protection are also put forward higher requirements.By incorporating fillers into silicone rubber

both the relative dielectric constant and breakdown field strength can be significantly improved.Common fillers include high relative dielectric constant fillers

wide bandgap fillers

carbon-based fillers

metallic fillers

and hybrid fillers.This paper summarizes the existing research to enhance silicone rubber composites'dielectric and insulation performance and offers insights into prospects in this field.
