Abstract
The invention discloses a kind of H levels flexible composite insulation material, including polyimide film layer, the upper and lower surface of the polyimide film layer is bonded with aramid insulating paper A, aramid insulating paper B by bond layer A, bond layer B respectively；The advantages of there is cost to reduce and meet H level motor insulating requirements by the present invention, the good opportunity further developed can be provided to focus on the middle and small motor manufacturing enterprise of cost.
Description
Technical field
The invention belongs to insulating materials technical field, is related to a kind of flexible composite insulation material, and in particular to a kind of H levels are soft
Soft composite insulating material.
Background technology
Existing H levels flexible composite insulation material production import Du Pont Dupont Nomex gather fragrant fibrous paper cost too
Height, govern promoting the use of for H level flexible composite insulation materials so that some focus on the middle and small motor manufacturer production of cost
Motor product can not be further developed.
With the development of insulating material technology, import Du Pont Dupont Nomex can be substituted to gather fragrant fiber completely
The electrical insulation product of paper starts to emerge in large numbers, wherein the most prominent with aramid insulating paper.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, and providing a kind of cost reduces and meets H level motors
The flexible composite insulation material of insulating requirements.
The object of the present invention is achieved like this：A kind of H levels flexible composite insulation material, including polyimide film layer,
The upper and lower surface of the polyimide film layer is bonded with aramid insulating paper A, virtue by bond layer A, bond layer B respectively
Synthetic fibre insulating paper B.
Preferably, the aramid insulating paper A, aramid insulating paper B are right using the EKT series of company of domestic vast and boundless sky dragon nation production
Position aramid insulating paper is made.
Preferably, the aramid insulating paper A, aramid insulating paper B can also use the electric of domestic people Shi Da companies production
Insulation is made of aramid paper.
Preferably, the thickness of the H levels flexible composite insulation material is 0.15mm~0.4mm.
By adopting the above-described technical solution, the beneficial effects of the invention are as follows：The domestic aramid insulating paper reduced with cost
Substitution import Du Pont Dupont Nomex gather fragrant fibrous paper, and aramid insulating paper is with its lasting heat endurance, proud fire-retardant
Property, splendid electrical insulating property, outstanding chemical stability, excellent mechanical property and superpower radiation resistance, security protection,
The fields such as high temperature filtration, electric insulation and structural material are using increasingly extensive, the poly- virtues of substitution import Du Pont Dupont Nomex
The H level flexible composite insulation materials of fibrous paper production fully meet the insulating requirements of H level motors, and cost is minimized, for note
The middle and small motor manufacturing enterprise of weight cost provides the good opportunity further developed, has preferable social benefit and economic effect
Benefit.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of the present invention.
In figure：1st, aramid insulating paper A 2, bond layer A 3, polyimide film layer 4, bond layer B 5, aramid fiber are exhausted
Edge paper B.
Embodiment
Below by embodiment, and with reference to accompanying drawing, technical scheme is described in further detail.
As shown in figure 1, a kind of H levels flexible composite insulation material provided by the invention, including polyimide film layer 3, institute
State the upper and lower surface of polyimide film layer 3 respectively by bond layer A2, bond layer B4 be bonded with aramid insulating paper A1,
Aramid insulating paper B5, aramid insulating paper A1 and aramid insulating paper B5 superior performances, cost is low, for substituting import Du Pont Dupont
Nomex gathers fragrant fibrous paper.
Further, the aramid insulating paper A1, aramid insulating paper B5 use the EKT systems of company of domestic vast and boundless sky dragon nation production
Row p-aramid fiber insulating paper is made, and the integrated cost of the aramid insulating paper of company of domestic vast and boundless sky dragon nation production is only main competition pair
The performance indications of 1/8th of hand, permeability and tensile strength etc. 70% exceed the like product of rival, and its EKT series is right
Position aramid insulating paper is applied to the slot insulation of various transformer motors, mutually layer insulation, insulation and turn-to-turn insulation, can substitute completely
Import Du Pont Dupont Nomex gather fragrant fibrous paper.
Further, the aramid insulating paper A1, aramid insulating paper B5 can also use the production of domestic people Shi Da companies
Electric insulation is made of aramid paper, and the high and low deformation of aramid paper intensity of domestic people Shi Da companies production, high temperature resistant, chemically-resistant are rotten
Erosion, radiation hardness, fire-retardant, electrical insulating property is excellent, has good mechanical performance and high-temperature insulation characteristic, its electric insulation virtue
Temperature resistant grade of the synthetic fibre paper through UL certifications is 210 DEG C, can reach H levels with its manufactured electronic product（180℃）Heatproof above
The class of insulation, because aramid paper is indeformable, non-fusible at high temperature, improves electronic product and temporarily bear overheat and excess load
Ability, and making insulating materials using aramid paper can make electronic product compact durable, and its size and weight substantially reduce, main to use
In coils in transformers, winding interlayer dielectic, between insulation sleeve, part, wire and joint insulating materials；Motor and generating
Between machine coil winding, groove, alternate, turn-to-turn, line terminal insulating materials；Cable and wire insulation, the insulation of nuclear-plant
Material etc., import Du Pont Dupont Nomex can be substituted to gather fragrant fibrous paper completely.
Further, the thickness of the H levels flexible composite insulation material is 0.15mm~0.4mm.
Here is the present invention（The EKT series p-aramid fiber insulating papers produced using company of domestic vast and boundless sky dragon nation）It is each
Item technical performance index：
As seen from the above table, the H levels produced using the EKT series p-aramid fibers insulating paper of company of domestic vast and boundless sky dragon nation production are soft multiple
The requirement that insulating materials property indices are satisfied by the insulation of H levels motor is closed, import Du Pont Dupont can be substituted completely
Nomex gathers fragrant fibrous paper.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations, although
The present invention is described in detail with reference to above-described embodiment, it should be understood by a person of ordinary skill in the art that still may be used
Modified or equivalent substitution with the embodiment to the present invention, and repaiied without departing from any of spirit and scope of the invention
Change or equivalent substitution, it all should cover among scope of the presently claimed invention.
