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 of the diaphragm that is used for using on the digital product.
Background technology
Along with development of science and technology, 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,, thereby influence the attractive in appearance of its outward appearance to the shell or the screen generation cut of these digital products.Therefore, the user can use diaphragm usually, hides on its shell or screen.Especially on the screen of digital product, the place that the most normal use diaphragm of the person of being to use is protected.Especially with the screen of mobile phone products, it uses diaphragm to prevent the cut protection, and is the most common.
Because digital product has great demand, therefore, the market demand of corresponding protection film also is very big.Therefore, industry manufacturer continues to increase the research and development input of diaphragm, in the hope of obtaining the diaphragm of better effects if.
And at present, the diaphragm that industry is developed, after it was attached on the screen, screen light can directly be transmitted to the front, and just 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
In order to overcome the diaphragm that industry is used at present, the problem of its surperficial printing opacity the invention provides a kind of manufacture method of diaphragm, the diaphragm that it produces, be attached on the screen after, its no printing opacity in surface.
The present invention solves the technical scheme that the prior art problem adopted: a kind of manufacture method of diaphragm, it includes following steps.Raw material high viscosity transparent polyester film is carried out rotary press kill glue.To killing high viscosity transparent polyester film behind the glue low viscosity transparent polyester film of fitting, form the printing ground.The printing ground is carried out white background partly to be printed and the chrominance section printing.
Further, in different embodiments, wherein kill the high viscosity transparent polyester film behind the glue, its low viscosity transparent polyester film of just fitting on the surface to subregion wherein is to form the printing ground.
Further, in different embodiments, wherein carry out white background printing partly on the ground to printing earlier, and then carry out the printing of chrominance section.
Further, in different embodiments, wherein the mode of printing of white background part is the serigraphy white background on the ground.
Further, in different embodiments, wherein ground enamel the part mode of printing be the 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.Its front is used for printing, and reverse side then has higher tack, and its viscosity degree is in 0.8～1.8kg/25mm scope.
Further, in different embodiments, wherein relate to the low viscosity transparent polyester film of use, a kind of transparent weak viscous plastic that it uses for industry.Its reverse side has certain viscosity, and its viscosity degree is about 0.2kg/mm.
The invention has the beneficial effects as follows, the diaphragm that it is prepared, when being used to attach on the display screen, its no printing opacity in surface can well be protected display screen.
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, with the protection display screen.Certainly, it also can be attached at other places of digital product or be used for other products, and not necessarily is confined to digital product, and concrete the application can be decided with user's needs, do not limit
Particularly, the manufacture method of the diaphragm that the present invention relates to, it includes following steps.
The first step is carried out rotary press to raw material high viscosity transparent polyester film and is killed 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.Its front is used for printing, and reverse side then has higher tack, and its viscosity degree is in 0.8～1.8kg/25mm scope.Therefore, be the counter productive of avoiding its high viscosity to produce, in this step, it killed glue, to remove its viscosity.
In second step,, form the printing ground to killing high viscosity transparent polyester film behind the glue low viscosity transparent polyester film of fitting.
In this step, wherein relate to the low viscosity transparent polyester film of use, a kind of transparent weak viscosity plastics materials that it uses for industry.Its reverse side has certain viscosity, and its viscosity degree is about 0.2kg/mm.
And, wherein killing the high viscosity transparent polyester film behind the glue, its low viscosity transparent polyester film of just wherein can fitting on the surface of subregion is to form the printing ground.Usually not the low viscosity transparent polyester film of all surfaces applying of the high viscosity transparent polyester film behind the whole glue extremely.Certainly, in other embodiments, also can be whole applyings, and indefinite.
In the 3rd step, the printing ground is carried out white background partly print.
In this step, the mode of printing of white background part is the serigraphy white background on the ground.
In the 4th step, the printing ground is carried out the chrominance section printing.
In this step, ground enamel the part mode of printing be the lithographic printing chrominance section.
By the diaphragm that the diaphragm manufacture method that the present invention relates to is prepared, when being used to attach on the display screen, its no printing opacity in surface can well be protected display screen.
The above only is a better embodiment of the present invention; protection scope of the present invention is not exceeded with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
