Abstract
The utility model is related to a kind of two-sided cover layer, including mainly having release liners or mould release membrance, PI films, glue-line and BOPP film, the upper exterior surfaces on PI films surface are provided with glue-line, glue-line bonding release liners or mould release membrance, PI films lower floor outer surface bonding glue-line, glue-line is adhered by BOPP film；This two-sided cover layer utilizes PI films to be base material, solves to performances such as high dimensional stability, heat resistance and mechanical strengths, and needs the two-sided cover layer all with specific functions such as insulating properties and cementabilities to require.
Description
Technical field
The utility model is related to covering technical field of membrane, more specifically a kind of two-sided cover layer.
Background technology
The cover layer that existing FCP industries are used all is that PI films are base material, with import epoxy modified resin or acrylic resin
For bonding agent, protected with release liners or mould release membrance, be mainly used in FPC plate surfaces and play a part of to cover insulation protection, also transport
Surface bonding used in precise electronic handware insulate, such as computer, insulation protection of cell connector of handheld device etc. etc., but
It is common cover layer, only one side has bonding agent, it is necessary to first press on the circuit or handware that some needs are bonded up and down simultaneously
Cover layer is closed, then last layer adhesive is carried on the back from the PI faces of cover layer, this not only takes, and efficiency is low while increasing cost again.
Especially in the case of using PI film base materials, there is the property such as high dimensional stability, heat resistance and mechanical strength
Can, and need two-sided all with the seldom of the specific functions such as insulating properties and cementability.
Therefore, it is necessary to develop a kind of two-sided cover layer.
The content of the invention
The purpose of this utility model is to overcome the defect of prior art, and there is provided a kind of two-sided cover layer, it is possible to resolve common
The cementability of PI cover layers and the superperformance of insulating properties, to achieve the above object, the utility model uses following technical scheme：
A kind of two-sided cover layer, including mainly have release liners or mould release membrance, PI films, glue-line and BOPP film, described PI films
The upper exterior surfaces on surface are provided with glue-line, glue-line bonding release liners or mould release membrance, and described PI films lower floor outer surface bonds glue-line,
Glue-line is adhered by BOPP film.
Described glue-line is made up of epoxy or acrylate glue.
Described epoxy or the glue thickness of acrylate glue are 8~50um.
Described PI film thicknesses are 7.5~50um.
Described BOPP film thickness is 25~50um, and with different glossiness.
The beneficial effect of the utility model compared with prior art is：This two-sided cover layer is base material using PI films, is solved
To performances such as high dimensional stability, heat resistance and mechanical strengths, and needs are two-sided all special with insulating properties and cementability etc.
The cover layer requirement of function.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Reference
(1) PI films；(2) glue-line；(3) release liners or mould release membrance；(4) BOPP film.
Embodiment
In order to more fully understand technology contents of the present utility model, with reference to specific embodiment to skill of the present utility model
Art scheme is further described and illustrated, but is not limited to this.
It is shown in Figure 1, a kind of two-sided cover layer, including mainly have release liners or mould release membrance (3), PI films (1), glue-line
(2) and BOPP film (4), the upper exterior surfaces on PI films (1) surface are provided with glue-line (2), glue-line (2) bonding release liners or mould release membrance
(3), PI films (1) lower floor outer surface bonding glue-line (2), glue-line (2) is adhered by BOPP film (4).
Glue-line (2) is made up of epoxy or acrylate glue, and the glue thickness of epoxy or acrylate glue is 8~50um, bonds upper strata
Mould release membrance or release liners (3) and lower floor's BOPP film (4).
PI films (1) thickness is 7.5~50um.
The beneficial effect of the utility model compared with prior art is：This two-sided cover layer is base material using PI films, is solved
To performances such as high dimensional stability, heat resistance and mechanical strengths, and needs are two-sided all special with insulating properties and cementability etc.
The cover layer requirement of function.
It is above-mentioned that technology contents of the present utility model are only further illustrated with embodiment, in order to which reader is easier to understand,
But embodiment of the present utility model is not represented and is only limitted to this, and any technology done according to the utility model extends or recreated,
By protection of the present utility model.Protection domain of the present utility model is defined by claims.
