Problems solved by technology

However, because cycloaliphatic epoxy resin insulators are used outdoors, they face aging problems caused by environmental factors such as outdoor temperature, humidity, and ultraviolet rays.
Existing cycloaliphatic epoxy resin insulators are prone to aging, and the mechanical strength declines sharply after aging, resulting in a short service life

Abstract

The invention provides an alicyclic epoxy resin insulating material, which comprises the following components in percentage by weight: 20%-30% of epoxy resin, 18%-25% of anhydride curing agent, 0.2%-0.3% of amine accelerant, 28%-35% of silica powder, 18%-25% of aluminum hydroxide and 1%-8% of nano composite material; wherein the nano composite material is prepared from coupling agent modified nanoaluminum oxide and coupling agent modified nano silicon oxide, and the weight ratio of the coupling agent modified nano aluminum oxide to the coupling agent modified nano silicon oxide is (1-4) : (1-4). According to the alicyclic epoxy resin insulating material disclosed by the invention, the epoxy resin, the anhydride curing agent and the amine accelerant are matched, and the coupling agent modified nano aluminum oxide and the coupling agent modified nano silicon oxide are combined as a nano composite material, so that the damp-heat resistance and the ultraviolet aging resistance of the alicyclic epoxy resin insulating material are remarkably improved, the service life of the alicyclic epoxy resin insulating material is prolonged, and the safety performance is improved when the alicyclicepoxy resin insulating material is used as an outdoor insulator material.

Description

technical field [0001] The invention relates to the field of high-voltage transmission insulating materials, in particular to an alicyclic epoxy resin insulating material. Background technique [0002] Composite insulators, as one of the widely used devices in power transmission systems, play an important role in electrical insulation and mechanical support, and their operating conditions are directly related to the stability and safety of power transmission systems. With the extensive application of silicone rubber composite insulators, problems that cannot be solved at present have also been discovered. First of all, since the shed sheath of the silicone rubber composite insulator is made of silicone rubber, the material of the silicone rubber is soft, and it is easily broken by external forces such as strong winds and bird pecks. Secondly, since the mandrel and sheath of the silicone rubber composite insulator are made of different composite materials, there must be a ma...
