Abstract

The invention discloses an efficient inflaming-retarding alicyclic epoxy resin outdoor insulator castable. The castable comprises, by weight, 100-200 parts of alicyclic epoxy resin, 50-200 parts of acuring agent, 0.1-50 parts of an accelerant, 1-50 parts of a flame retardant and 50-500 parts of filler. The flame retardant is one of 2,4,6-tribromoaniline and antimony trioxide. According to the castable, by optimizing the kind of the flame retardant and matching of the application amount of all the components, the prepared insulator castable has good outdoor weather resistance, heat resistance,insulation resistance, mechanical properties and flame resistance.

Description

technical field [0001] The invention relates to the technical field of outdoor high-voltage insulating materials, in particular to a high-efficiency flame-retardant alicyclic epoxy resin castable for outdoor insulators. Background technique [0002] Insulators are widely used insulation equipment in transmission and distribution networks. Although the cost is low and the structure is simple, they play an indispensable role in the stable and safe operation of the entire power system. The failure of any one of the insulators may cause a safety accident of the entire power system. [0003] So far, insulators widely used in power systems mainly include porcelain insulators, glass insulators and silicone rubber composite insulators. Porcelain glass insulators have excellent mechanical properties and strong aging resistance, but the related electrical properties are poor and the weight is heavy. Silicone rubber composite insulators have excellent electrical properties, but poor ...
