Abstract
The utility model discloses a kind of polyimides sleeve pipe, the internal layer of sleeve pipe is polyimide film layer, outer layer is glass layer, also has tack coat between the polyimide film layer and glass layer, also has mica bisque inside the polyimide film layer.Polyimides sleeve pipe designed by the utility model; pass through the addition of glass fibre; make intensity and the flexility enhancing of sleeve pipe; pass through the addition of mica powder; make sleeve pipe that there is fire protecting performance; using binding agent and canoe, make sleeve structure close and firm, the electric insulation under various high temperature, high voltage, burn into radiation environment and protection can be applied.
Description
Technical field
It the utility model is related to a kind of insulating materials, and in particular to a kind of polyimides sleeve pipe.
Background technology
With the development of China's electric utility, as a part of electric utility China, insulating materials seem to
Close important.The effect of insulating materials is that the different live part of potential is kept apart in electricity plays equipment, therefore insulating materials
Should have higher insulaion resistance and compressive resistance, and be avoided that the accidents such as generation electric leakage, breakdown.
Polyimides has excellent mechanics, electricity and temperature characterisitic, compared with other high molecular polymers, polyimides
Ultra-fine footpath, the insulating sleeve of ultra-thin-wall can be made, there is high temperature resistant, high pressure resistant, high intensity, resistant to chemical etching, vacuum is low releases
The characteristics of gas, anti-nuclear irradiation.But polyimides sleeve pipe of the prior art is homogenous material straight forming, causes function single,
Without fire protecting performance, strict requirements are not met by terms of flexility and intensity.
Utility model content
Purpose of utility model：The purpose of this utility model is to be to provide a kind of polyimides sleeve pipe, and the sleeve pipe is except poly-
Also include glass layer, mica layer etc. outside acid imide film, multiple material is combined with each other, and has excellent insulation, fire prevention, soft
Tough performance.
Technical scheme：A kind of polyimides sleeve pipe, the internal layer of the sleeve pipe is polyimide film layer, outer layer is glass fibre
Layer, there is tack coat between the polyimide film layer and glass layer, also have cloud inside the polyimide film layer
Female powder layer.
Preferably, the tack coat is adhesive for polyurethane.The gluing stick of polyurethane possesses excellent rubber property, can fit
The bonding of different heat expansion coefficient base material is answered, it is formed between base material has soft-hard transition zone, and not only bonding force is strong, simultaneously
Also there is excellent buffering, shock-absorbing function, adhesive for polyurethane is as viscous between polyimide film layer and glass layer
Agent is tied, both base materials can be firmly bonded together.
Preferably, glass fibre lamellar spacing is wrapped outside polyimide film layer, is 0.2-0.3mm around Inter-packet gap.Using
Around-packing technology can make glass layer be bonded with polyimide film layer closer.
Preferably, fire-resistant isinglass belt is also wrapped on outside the glass layer, there is excellent resistance to elevated temperatures and resistance to combustion
Performance is burnt, with good flexibility during mica tape normality.
Preferably, the thickness of the polyimide film layer is 0.05-0.2mm, and the thickness of glass layer is 0.1-
0.2mm, the thickness of mica bisque is 0.08-0.12mm, and the thickness of tack coat is 0.002-0.005mm.
Beneficial effect：Polyimides sleeve pipe designed by the utility model, by the addition of glass fibre, make the strong of sleeve pipe
Degree and flexility enhancing, by the addition of mica powder, make sleeve pipe have fire protecting performance, using binding agent and canoe,
Make sleeve structure close and firm, the electric insulation under various high temperature, high voltage, burn into radiation environment and protection can be applied.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to deepen to understanding of the present utility model, the utility model is made below in conjunction with embodiment and accompanying drawing further

Embodiment 1
Polyimides sleeve pipe, the internal layer of the sleeve pipe is polyimide film layer 2, outer layer is glass layer 4, polyimides
There is tack coat 3 between film layer 2 and glass layer 4, there be mica bisque 1 inside of polyimide film layer 2.
Tack coat 3 is adhesive for polyurethane.The gluing stick of polyurethane possesses excellent rubber property, and it is swollen to adapt to different heat
The bonding of swollen coefficient base material, it is formed between base material has soft-hard transition zone, and not only bonding force is strong, while also has excellent
Buffering, shock-absorbing function, adhesive for polyurethane, can be by this as the binding agent between polyimide film layer and glass layer
Two kinds of base materials are firmly bonded together.
The gap of glass layer 4 is wrapped outside polyimide film layer 2, is 0.2-0.3mm around Inter-packet gap.Using around job contract
Skill can make glass layer be bonded with polyimide film layer closer.
Fire-resistant isinglass belt is also wrapped on outside glass layer 4, there is excellent resistance to elevated temperatures and flame resistance energy, mica
With good flexibility during with normality.The thickness of polyimide film layer is 0.05-0.2mm, and the thickness of glass layer is
0.1-0.2mm, the thickness of mica bisque is 0.08-0.12mm, and the thickness of tack coat is 0.002-0.005mm.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
