Insulating material for mutual inductor

Abstract

The invention discloses an insulating material for a mutual inductor. The insulating material is prepared from the following raw materials in parts by weight: 15-18 parts of epoxy resin glue, 5-9 parts of toluene diisocyanate, 3-7 parts of active silica powder, 6-9 parts of an expanded graphite fire retardant, 5-8 parts of chlorinated paraffin, 7-10 parts of organic silicon resin, 12-15 parts of mica powder, 4-7 parts of an antioxidant, 3-5 parts of polyimide, 4-6 parts of mineral fiber and 6-9 parts of a curing agent. The insulating material has the characteristics of anti-corrosion property, anti-oxidizing property, waterproof fire resistance, low smoke, no toxicity, no halogen, anti-flaming property, and higher tensile strength and thus is suitable for various mutual inductors.

Description

technical field [0001] The invention relates to the technical research and development field of transformer insulating materials, in particular to an insulating material for transformers. Background technique [0002] Today, with the rapid development of high technology, more and more electrical equipment enters and exits people's homes. In order to make people's lives safer, new insulating materials with better insulation effects are needed to insulate electrical equipment. In the existing work and life, the existing new insulating materials are manufactured according to common DIN standards, such as: heat-resistant 90 cross-linked polyethylene, polyvinyl chloride; its disadvantages are: not heat-resistant, not fire-resistant, more Not fireproof. Ordinary polyvinyl chloride materials with an insulation degree of 0.6-110 cannot be overloaded. Excessive current can easily break down the new insulating material and cause a short circuit; in an open flame, it is easy to be ign...

Problems solved by technology

In the existing work and life, the existing new insulating materials are manufactured according to the common DIN standard, such as: heat-resistant 90 cross-linked polyethylene, polyvinyl chloride; its disadvantages are: not heat-resistant, not fire-resistant, more Not fireproof

Ordinary PVC materials with an insulation degree of 0.6-110 cannot be overloaded, and the overloaded current can easily break down the new insulating material and cause a short circuit; in an open flame, it is easy to be ignited, releasing suffocating toxic gases and polluting the environment
