Abstract

The invention discloses a high-efficiency flame-retardant alicyclic epoxy resin casting material for outdoor insulators. The casting material includes the following components: 100-200 parts of cycloaliphatic epoxy resin, 50-200 parts of curing agent, 0.1-50 parts of accelerator, 1-50 parts of flame retardant and 50-500 parts of filler, wherein, All parts are by weight, and the flame retardant is at least one of 2,4,6-tribromoaniline and antimony trioxide. In the present invention, by optimizing the type of flame retardant and the dosage ratio of each component, the prepared insulator castable has good outdoor weather resistance, heat resistance, insulation, mechanical properties and flame retardancy.

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 ...
