Abstract

The utility model provides a protective film structure for an electronic product, which comprises an anti-static layer, a releasing layer stacked on the top surface of the anti-static layer, an adhesive layer stacked on the top surface of the releasing layer, and a surface-layer substrate stacked on the surface of the adhesive layer. Therefore, in the protective film structure for the electronic product, the anti-static layer can be arranged at the lowermost layer of a protective film (a surface not in contact with the adhesive layer), so that when all protective films are stacked or furled for storage, as the anti-static layer is arranged, static electricity generated by mutual friction of all the protective films when the protective films are taken for use can be avoided, so as to prevent the protective films from attracting dust in the environment due to electrostatic discharge, not only prevent the appearance quality from being affected, but also eliminate the poor quality caused by the difficulty in taking the protective films for use due to the static electricity, and achieve the efficacies of effectively preventing the static electricity from generating and improving the reliability of the product.

Description

The protective film structure of electronic product

Technical field

The utility model relates to a kind of protective film structure; Relate in particular to a kind of bottom (one side that does not contact) that can antistatic layer be located at protective film with adhesion layer; Make each protective film one on top of another or furl when depositing, the setting of this antistatic layer capable of using, and avoid when taking because of the mutual friction generates static between each protective film; To prevent that protective film from attracting to belong to the dust of environment because of electrostatic discharge; Except that can avoid presentation quality influenced, also can get rid of when taking because of static causes and take that to be difficult for the related quality that causes of institute bad, and reach the protective film structure of the electronic product of the effect that effectively prevents generation of static electricity and increase production reliability.

Background technology

Flourish along with electronics technology; Make electronics packages such as vehicular telephone, camera, digital camera, notebook computer make rapid progress; And portably use for ease of the user; These electronics packages all with light, thin, short, little as main demand, so the mechanism of electronic product fixedly protective film change adhesive tape class protective film into by conventional screw in a large number, also use cuticula class protective film to protect in processing procedure and the shipment in a large number; The processing procedure and the shipment

protective film

2,3,4,5 (like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4) of the general electronic product mechanism that uses always include following four kinds of kenels at least:

The first by mould release membrance/paper 21, be located at glue-line 22 on mould release membrance/paper 21 one side, be located at the base material 23 on the glue-

line

22 and 24 of antistatic layers being located on the base material 23 constitute;

It two is by mould release membrance/paper 31, be located at glue-line 32 on mould release membrance/paper 31 one side, be located at the antistatic layer 33 on the glue-

line

32 and 34 of base materials being located on the antistatic layer 33 constitute;

It three is by mould release membrance/paper 41, be located at antistatic layer 42 on mould release membrance/paper 41 one side, be located at the glue-line 43 on the

antistatic layer

42 and 44 of base materials being located on the glue-line 43 constitute;

It four is by mould release membrance/paper 51, is located at the antistatic glue-line 52 on mould release membrance 51 one side and 53 of base materials being located on antistatic glue-line 52 one sides constitute;

Yet; With the protective film 2 of above-mentioned Fig. 1 for example; It can avoid attracting the context dust to influence presentation quality or causing the difficult problem of taking because of static when causing taking because of electrostatic discharge; But, therefore, can separate out the testing result that influences contact panel because of characteristic or antistatic material of its a small amount of conduction because of the antistatic layer 24 of this protective film 2 is located at the surface (one side that does not contact with glue-line 22) of protective film 2; Moreover with other

protective film

3,4,5 commonly used; All can be because of the position that is provided with of its

antistatic layer

33,42 and antistatic glue-line 52; And make this

protective film

3,4,5 one on top of another or furl deposit after; Still can produce static because of the phase mutual friction between each protective film when taking; And then make this

protective film

3,4,5 be located at when using on the Touch Screen, can cause

protective film

3,4,5 to attract the context dusts to influence presentation quality or to take the difficult related quality that causes bad because of static causes when causing taking because of electrostatic discharge, and then influence the operation of Touch Screen.

Therefore, how creating a kind of protective film of electronic product structure, so that it effectively increases the effect of production reliability under the testing result that can not influence electronic product, can reach it again and use the time, will be that the utility model desires actively to disclose part.

Summary of the invention

Because the defective of above-mentioned existing protective film of electronic product; It does not reach perfection contriver's thoughts; Then exhausting the concentrated research of its intelligence overcomes; Be engaged in this industry accumulating experience for many years with it, and then develop a kind of protective film structure of electronic product, effectively prevent generation of static electricity and the purpose that increases production reliability in the hope of reaching.

The main purpose of the utility model is providing a kind of protective film of electronic product structure; It is through being located at this antistatic layer the bottom (one side that does not contact with adhesion layer) of protective film; Cause each protective film when one on top of another or volume are deposited, the setting of this antistatic layer capable of using, and avoid when taking because of the mutual friction generates static between each protective film; To prevent that protective film from attracting to belong to the dust of environment because of electrostatic discharge; Except that can avoid quality influenced, also can get rid of when taking because of static causes and take that to be difficult for the related quality that causes of institute bad, and then reach the purpose that effectively prevents generation of static electricity and increase production reliability.

For reaching above-mentioned purpose, the protective film structure of the electronic product of the utility model comprises: antistatic layer; Release layer on the antistatic layer end face one on top of another; Adhesion layer on the release layer end face one on top of another; And one on top of another in the lip-deep top layer of adhesion layer base material.

In an embodiment of the utility model, this protective film can be monolithic body or processes drum with majority mode arranged side by side.

In an embodiment of the utility model; This release layer is the layer of the material of PET, PC, PE, stationery or fibrous glass; This adhesion layer is the layer of PU glue, rubber, silica gel or acrylate glue, and the layer that this top layer base material is the material of PET, PC, PE, stationery or fibrous glass.

Thus, the protective film structure of a kind of electronic product of the utility model can be located at this antistatic layer the bottom of protective film; Make each protective film one on top of another or furl when depositing; The setting of this antistatic layer capable of using, and avoid when taking attracting to belong to the dust of environment because of the mutual friction generates static between each protective film because of electrostatic discharge to prevent protective film; Except that can avoid quality influenced, also can get rid of when taking because of static cause take be difficult for the related quality that causes bad.
