Description
Technical field
The utility model is related to a kind of PET composite membranes, and in particular to can be used as the PET composite membranes of soft insulating cylinder.
Background technology
PET film is to be coated with the composite flexible material that adhesive is combined by multilayer PET film, has preferable dielectricity
Energy, puncture resistance, low-shrinkage, agent of low hygroscopicity and high heat resistance.The product is widely used in industrial, civilian, agriculture etc.
In many fields.Electronics industry requires higher to it, it is desirable that its is wear-resistant, scratch resistant, insulating properties are stronger, and existing PET is multiple
It closes film strength and insulating properties is all relatively low, industry requirement is generally not achieved.
Utility model content
The purpose of this utility model is to provide the PET composite membranes that can be used as soft insulating cylinder, solve existing PET composite membranes
Its intensity and the relatively low problem of insulating properties.
The utility model is achieved through the following technical solutions：
It can be used as the PET composite membranes of soft insulating cylinder, including PET basement membranes, two layers outer PET basement membranes, two layers of insulating film in one layer,
The interior PET basement membranes are located at middle layer, and the two sides of interior PET basement membranes is provided with several semi-enclosed grooves, and the one of every layer of insulating film
Side is provided with several raised lines, another side is bonded with one layer of outer PET basement membrane, and the raised line is mutually matched with groove.
Further, for the above technical problem, the utility model devises a kind of novel PET composite membranes, in tradition
The composite construction that only single PET basement membranes are formed in increase by two layers of insulating film, utilize unlike material insulation than different, breakdown ratio
Characteristic so that PET composite membranes can be formed in the soft insulating cylinder as dry-type transformer multilayer barrier effect, avoid single
The problem of material is easily polarized so that the insulating properties of the PET composite membranes of the utility model greatly increases.And five layer interlayer structures
Compared to the composite construction that existing single PET basement membranes are formed, since the density of every tunic is different, intensity also can be improved.This
Multiple grooves are opened in the two sides of interior PET basement membranes by utility model, and insulating film is bonded with the matching of interior PET basement membranes, contact area bigger,
Connection also can more stablize when compressing, and can improve compound film strength.The interior PET basement membranes and outer PET basement membranes of the utility model are all
It is PET basement membranes in the prior art for a kind of material.
The interior PET basement membranes, insulating film, the outer PET basement membranes matched five-layer structure of institute by electrospinning and drop stamping one at
Type.Multilayered structure is directly formed into integral structure by electrospinning and the technological means of drop stamping, avoids the hierarchy of multilayer
Structure, further avoids the layering of general composite structure, greatly extends actual service life.
Preferably, the depth of the groove is the one third of interior PET basement membrane thickness.
The insulating film is silicon nitride film.Silicon nitride film is the film of silicon-nitrogen compound, with chemical vapor deposition and sputtering
Prepared by method, prepared by generally use plasma activated chemical vapour deposition, has high rigidity and excellent chemical stability, is very by head
Depending on wear-resisting erosion resistance film, be commonly used for microelectric technique electric insulation layer.
The utility model compared with prior art, has the following advantages and advantages：
1, the utility model can be used as the PET composite membranes of soft insulating cylinder, can in the soft insulating cylinder as dry-type transformer
Multilayer barrier effect is formed, avoids the problem of single material is easily polarized so that the insulation of the PET composite membranes of the utility model
Property and intensity greatly increase；
2, the utility model can be used as the PET composite membranes of soft insulating cylinder, and insulating film is bonded with the matching of interior PET basement membranes, connects
Contacting surface accumulates bigger, and connection also can more stablize when compressing, and can improve compound film strength；Pass through the technology hand of electrospinning and drop stamping
Multilayered structure is directly formed integral structure by section, is avoided the hierarchical structure of multilayer, is further avoided general plyability
The layering of structure greatly extends actual service life.
Description of the drawings
Attached drawing described herein is used for providing further understanding the utility model embodiment, constitutes the one of the application
Part does not constitute the restriction to the utility model embodiment.In the accompanying drawings：
Fig. 1 is the cross-sectional view of the utility model.
Label and corresponding parts title in attached drawing：
PET basement membranes in 1-, the outer PET basement membranes of 2-, 3- insulating films, 4- grooves.
Specific implementation mode
To make the purpose of this utility model, technical solution and advantage be more clearly understood, with reference to embodiment and attached drawing,
The utility model is described in further detail, and the exemplary embodiment and its explanation of the utility model are only used for explaining this
Utility model is not intended to limit the scope of the present invention.
Embodiment
As shown in Figure 1, the utility model can be used as the PET composite membranes of soft insulating cylinder, including PET basement membranes 1 in one layer, two layers
Outer PET basement membranes 2, two layers of insulating film 3, the interior PET basement membranes 1 are located at middle layer, and the two sides of interior PET basement membranes 1 is provided with several partly
Closed groove 4, the one side of every layer of insulating film 3 is provided with several raised lines, another side is bonded with one layer of outer PET basement membrane 2, institute
Raised line is stated to be mutually matched with groove 4.The interior PET basement membranes 1, insulating film 3, the 2 matched five-layer structure of institute of outer PET basement membranes pass through electricity
It spins and drop stamping is integrally formed.The depth of the groove 4 is the one third of interior 1 thickness of PET basement membranes.The insulating film 3 is nitrogen
SiClx film.The above structure is insulated using unlike material than the characteristic of different breakdown ratios so that PET composite membranes become as dry type
Multilayer barrier effect can be formed when the soft insulating cylinder of depressor, avoids the problem of single material is easily polarized so that this practicality is new
