Abstract

The invention belongs to the technical field of preparation of electrical insulating materials, and in particular relates to an epoxy resin insulating material and its preparation method and application. The raw materials of the epoxy resin insulating material include 92-107 parts of epoxy resin, 20-50 parts of silicone modified resin and 130-190 parts of filler, and the Si-CH in the silicone modified resin 3 The molar content is 23.33%‑47.17%. This insulating material contains a large amount of Si‑CH 3 The silicone modified resin can modify the epoxy resin, which can make the epoxy resin have better hydrophobicity and water repellency. At the same time, the silicone modified resin can also form a network crosslinked structure with the epoxy resin, improving The mechanical strength and impact strength of epoxy resin insulation materials; by adding fillers to the epoxy resin, the hydrophobicity, low-temperature brittleness and impact strength of the epoxy resin can be further improved in combination with physical filling modification technology.

Description

technical field [0001] The invention belongs to the technical field of preparation of electrical insulating materials, and in particular relates to an epoxy resin insulating material and its preparation method and application. Background technique [0002] External insulation is the area where most accidents occur in power systems. The level of external insulation significantly affects the safe operation of power systems. The improvement and promotion of external insulation performance has always been one of the focuses of power system research. All kinds of line insulators need to meet the technical requirements of electrical performance, mechanical performance and aging resistance in the long-term complex and harsh operating environment. External insulation materials are naturally one of the key contents of the external insulation research of power systems. As far as the overall application of external insulating materials is concerned, electric porcelain and glass are the...
