Description
Technical field
Insulator arrangement technical field is the utility model is related to, more specifically to a kind of insulating paper.
Background technology
It is well known that in the prior art, insulating paper uses Kapton and the compound technique of insulating paper more, first
After polyimide resin is made film, it is compound with insulating paper to reuse adhesive.However, above-mentioned complex process, flow is more, into
This height, and it is poor using the compound lamination easily produced of adhesive, the stability and reliability of insulating materials.
In conclusion the problems such as how efficiently solving the quality stability and poor reliability of insulating paper, is current sheet
Field technology personnel's urgent problem.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of insulating paper, the structure design of the insulating paper to have
Effect ground solves the problems, such as that the quality stability of insulating paper and reliability are poor.
In order to achieve the above object, the utility model provides following technical solution：
A kind of insulating paper, including insulating paper layer, further include directly coated on the insulating paper layer surface, to it is described absolutely
Edge ply of paper bonding and the polyimide resin layer to form a film.
Preferably, the surface straight forming of the insulating paper layer has the polyimide resin layer of preset shape.
Preferably, the preset shape is specially circular, triangle or rectangle.
Preferably, the tow sides of the insulating paper layer are both provided with the polyimide resin layer.
Preferably, the insulation recto is all covered with the polyimide resin layer.
Preferably, the back side of the insulating paper is all covered with the polyimide resin layer.
During using insulating paper provided by the utility model, directly by polyimide resin coated on insulating paper layer surface into
Film, reduces the process that adhesive fitting insulating paper is reused after individually polyimides is formed a film.Production cost is reduced, is improved
The stability and reliability of product quality, eliminates the phenomenon being loosely layered using adhesive bond.Available for H grades of motors,
Slot insulation in electric appliance, turn-to-turn insulation, phase insulation and pad insulate, and can also be B, the insulation of F grades of electrical equipment and electrical privileged sites,
Insulation performance is reliable, service life length.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is the structure diagram of the insulating paper of one specific embodiment of the utility model.
Marked in attached drawing as follows：
Insulating paper layer 1, polyimide resin layer 2.
Embodiment
The utility model embodiment discloses a kind of insulating paper, to improve the quality stability of insulating paper and reliability.
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, Fig. 1 is the structure diagram of the insulating paper of one specific embodiment of the utility model.
In one embodiment, insulating paper provided by the utility model includes insulating paper layer 1 and polyimide resin layer 2.
Wherein, insulating paper layer 1 can use insulating paper conventional in the prior art, can not specifically limit.Polyamides is sub-
Amine resin layer 2 forms a film and is bonded with the insulating paper layer 1 to be directly coated at 1 surface of insulating paper layer.Namely polyamides is sub-
Amine resin layer 2 is by the bonding that forms a film, because without being bonded by adhesive etc. directly with insulating paper layer 1.
During using insulating paper provided by the utility model, directly by polyimide resin coated on 1 surface of insulating paper layer into
Film, reduces the process that adhesive fitting insulating paper is reused after individually polyimides is formed a film.Production cost is reduced, is improved
The stability and reliability of product quality, eliminates the phenomenon being loosely layered using adhesive bond.Available for H grades of motors,
Slot insulation in electric appliance, turn-to-turn insulation, phase insulation and pad insulate, and can also be B, the insulation of F grades of electrical equipment and electrical privileged sites,
Insulation performance is reliable, service life length.
Further, the surface programming position straight forming of insulating paper layer 1 has the polyimide resin layer of preset shape.According to
Specifically need the situation to insulate, it is possibility to have selectively preset shape in the surface programming position straight forming of insulating paper layer 1
The polyimide resin layer of shape.
Specifically, the preset shape can be circular, triangle or rectangle.Or multiple circular, triangles or rectangle
Combination etc..Specific preset shape need to need to be configured according to client to the specific of an insulating shroud.
On the basis of the various embodiments described above, the tow sides of insulating paper layer 1 are both provided with polyimide resin layer 2.
Be exactly can the single or double of insulating paper layer 1 be coated with polyimide resin, formed polyimide resin layer 2, be made NH or
The polyimide composite insulated paper of NHN types, to meet different user's use demands.Figure of description 1 shows NHN types
Insulating paper structure, namely be directly coated with polyimide resin layer 2 in the tow sides of insulating paper layer 1；And it is directed to NH
