Problems solved by technology

When polyimide is used in the middle organic insulating layer, the overall insulating film is thin (usually 0.12-0.13mm), and it is easy to be pierced during the assembly process, resulting in poor voltage resistance
However, when glass fiber is used in the middle organic insulating layer, the tensile strength and tear strength of the insulating film are insufficient, and it is easy to tear

Abstract

The invention discloses an organic insulating film which comprises a first heat conduction layer, a first organic insulating layer, an enhancement layer, a second organic insulating layer and a secondheat conduction layer, which are sequentially arranged from top to bottom; the first heat conduction layer and the first organic insulating layer are connected through a first adhesive layer; the first organic insulating layer and the enhancement layer are connected through a second adhesive layer, the enhancement layer and the second organic insulating layer are connected through a third adhesive layer, and the second organic insulating layer and the second heat conduction layer are connected through a fourth adhesive layer. Through cooperation of the first heat conduction layer, the first adhesive layer, the first organic insulation layer, the second adhesive layer, the enhancement layer, the third adhesive layer, the second organic insulation layer, the fourth adhesive layer and the second heat conduction layer, the organic insulation film has good tear resistance and puncture resistance.

Description

technical field [0001] The invention belongs to the technical field of insulating films, and in particular relates to an organic insulating film. Background technique [0002] The insulating film is a thin film capable of ensuring good electrical insulation, which has a high resistivity (higher than 1010 Ω·cm) and a breakdown field strength. There are mainly two types of insulating films at present. One is that the middle organic insulating layer is made of polyimide, and the two sides are heat-conducting layers; the other is that the middle is glass fiber, and both sides are heat-conducting layers. When polyimide is used in the middle organic insulating layer, the overall insulating film is relatively thin (usually 0.12-0.13mm), and it is easy to be pierced during the assembly process, resulting in poor voltage resistance. However, when glass fibers are used in the middle organic insulating layer, the tensile strength and tearing strength of the insulating film are insuffi...
