Research on the Influence of Powder and Its Surface Modification to the Flame Retardant, Electric Performance and Mechanical Properties of Silicone Potting Material

performance Abstract. A silicone resin as base material, composite powder as filler, and the electronic potting silicone material was prepared using a silane coupling agent γ-3(trimethylsilyl) propyl methacrylate (KH-570) to do surface treatment. The influence of surface modification and its amount on the flame retardant, electric performance and mechanical properties of silicone potting material was studied in this paper. The developed organic silicon electronic potting materials with good flame retardant, electric performance, and mechanical performance, could be used in the high voltage grade of products, and meet the electrical performance requirements of an arrester.
