Abstract
The invention relates to a manufacturing method for a protective film, comprising the following steps: removing glue of a raw material high-viscidity transparent polyester film by a rotary printer; adhering the processed high-viscidity transparent polyester film to a low-viscidity transparent polyester film material to form a printed substrate; and printing a white bottom part and a color part of the printed substrate. The protective film is manufactured according to the manufacturing method for a protective film; and then the protective film has non-light-transmission surface and protects the display screen when used for attaching to the display screen of the digital product.
Description
Technical field
The present invention relates to a kind of manufacture method of diaphragm, especially a kind of manufacture method for the diaphragm that uses on digital product.
Background technology
Along with scientific and technological development, digital product has also obtained great development.This is wherein swift and violent by the development with mobile phone products.
In order to prevent usual use, the shell to these digital products or screen produce cut, thereby affect the attractive in appearance of its outward appearance.Therefore, user can use diaphragm conventionally, hides on its shell or screen.Especially on the screen of digital product, be the place that user the most often uses diaphragm to protect.Especially with the screen of mobile phone products, it uses diaphragm to carry out scratch protection, the most common.
Because digital product has the huge market demand, therefore, the market demand of corresponding diaphragm is also very large.Therefore, the research and development that industry manufacturer continues to increase diaphragm drop into, to obtaining the diaphragm of better effects if.
And at present, the diaphragm that industry is developed, after it is attached on screen, screen light can directly be transmitted to front, and namely its surface meeting printing opacity makes it can not thoroughly protect display screen.
Therefore, industry is badly in need of a kind of novel diaphragm manufacture method, improves or addresses the above problem.
Summary of the invention
The diaphragm using at present in order to overcome industry, the problem of its surperficial printing opacity, the invention provides a kind of manufacture method of diaphragm, the diaphragm that it produces, after being attached on screen, its surface is without printing opacity.
The present invention solves the technical scheme that prior art problem adopts: a kind of manufacture method of diaphragm, it includes following steps.Raw material high viscosity transparent polyester film is carried out to rotary press and kill glue.To killing high viscosity transparent polyester film after the glue low viscosity transparent polyester film of fitting, form printing ground.Printing ground is carried out to the printing of white background part and chrominance section printing.
Further, in different embodiments, wherein kill the high viscosity transparent polyester film after glue, it is just to the low viscosity transparent polyester film of fitting on the surface of subregion wherein, to form printing ground.
Further, in different embodiments, wherein first to carrying out the printing of white background part on printing ground, and then carry out the printing of chrominance section.
Further, in different embodiments, wherein on ground, the mode of printing of white background part is serigraphy white background.
Further, in different embodiments, wherein ground enamel part mode of printing be lithographic printing chrominance section.
Further, in different embodiments, wherein relate to the high viscosity transparent polyester film of use, a kind of plastic printing raw material that it uses for industry.It is positive, and for printing, reverse side has higher tack, and its viscosity degree is within the scope of 0.8～1.8kg/25mm.
Further, in different embodiments, wherein relate to the low viscosity transparent polyester film of use, the transparent weak viscous plastic of one that it uses for industry.Its reverse side has certain viscosity, and its viscosity degree is in 0.2kg/mm left and right.
The invention has the beneficial effects as follows, the diaphragm that it is prepared, when attaching on display screen, display screen, without printing opacity, can well be protected in its surface.
The specific embodiment
An embodiment of the invention relate to a kind of manufacture method of diaphragm, and the diaphragm that it produces can be used for being attached on the display screen of digital product, to protect display screen.Certainly, it is local or for other products that it also can be attached at other of digital product, and be not necessarily confined to digital product, and specifically application, can determine with user's needs, does not limit
Particularly, the manufacture method of the diaphragm the present invention relates to, it includes following steps.
The first step, carries out rotary press to raw material high viscosity transparent polyester film and kills glue.
In this step, wherein relate to the high viscosity transparent polyester film of use, a kind of plastic printing raw material that it uses for industry.It is positive, and for printing, reverse side has higher tack, and its viscosity degree is within the scope of 0.8～1.8kg/25mm.Therefore, be the counter productive of avoiding its high viscosity to produce, in this step, it is killed to glue, to remove its viscosity.
Second step, to killing high viscosity transparent polyester film after the glue low viscosity transparent polyester film of fitting, forms printing ground.
In this step, wherein relate to the low viscosity transparent polyester film of use, the transparent weak viscosity plastics materials of one that it uses for industry.Its reverse side has certain viscosity, and its viscosity degree is in 0.2kg/mm left and right.
And, wherein killing the high viscosity transparent polyester film after glue, its low viscosity transparent polyester film of just wherein can fitting on the surface of subregion, to form printing ground.Conventionally not the whole all surfaces that kills the high viscosity transparent polyester film after the glue low viscosity transparent polyester film of fitting.Certainly, in other embodiments, can be also whole laminatings, and indefinite.
The 3rd step, carries out the printing of white background part to printing ground.
In this step, on ground, the mode of printing of white background part is serigraphy white background.
The 4th step, carries out chrominance section printing to printing ground.
In this step, ground enamel part mode of printing be lithographic printing chrominance section.
The diaphragm of being prepared by the diaphragm manufacture method the present invention relates to, when attaching on display screen, display screen, without printing opacity, can well be protected in its surface.
The foregoing is only preferred embodiments of the present invention; protection scope of the present invention is not limited with above-mentioned embodiment; in every case the equivalence that those of ordinary skills do according to disclosed content is modified or is changed, and all should include in the protection domain of recording in claims.
