Description

The screen protecting film of protection liquid crystal display
Technical field
The utility model relates to a kind of diaphragm, particularly relates to a kind of screen protecting film protecting liquid crystal display.
Background technology
Flourish along with electronics technology, the electronic products such as MP4, MP5, mobile phone, camera, digital code camera, notebook computer are more and more widely used.But in the process using electronic product, the screen surface of electronic product is often easily scraped off or weares and teares, thus impact uses, and in order to avoid this phenomenon, generally can stick screen protecting film in the screen surface of electronic product.But the screen protecting film adopted in the market easily produces bubble when pasting; and not easily discharge; have impact on the aesthetics after product pad pasting; and the screen protecting film light transmittance used at present is not high; resistance to scraping is lower; the hard object scratches such as diaphragm is still easily pointed, suspension member, thus have impact on the service life of LCDs.
In view of this, how to design a kind of screen protecting film, strengthen resistance to scraping, and easily to install, not easily have bubble to be insider and in the problem solved.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provide a kind ofly be convenient to install, anti scuffing performance is good, can the screen protecting film of fast automatic eliminating bubble.
For achieving the above object, the technical solution of the utility model is: a kind of screen protecting film, comprise: the first diaphragm, first glue-line, scratch-resistant layer, main film base material, polyurethane glue-line, metal film, second glue-line and the second diaphragm, the corona surface of described main film base material is coated with described polyurethane glue-line to arrange, described polyurethane adhesive layer fits in the described metal film back side, the metal covering of described metal film is coated with described second glue-line, the non-corona surface of described second glue-line and described second diaphragm is fitted, the non-corona surface of described main film base material is coated with described scratch-resistant layer, the corona surface of described first diaphragm is coated with described first glue-line, described first glue-line and described scratch-resistant layer fit, wherein, described first protection thickness 15um ~ 45um, thick 3um ~ the 20um of described first glue-line, described anti-scratch thickness 3um ~ 8um, thick 50um ~ the 300um of described main film base material, described polyurethane adhesive thickness 4um ~ 30um, described metal film thickness 6um ~ 30um, thick 10um ~ the 40um of described second glue-line, described second protection thickness 15um ~ 45um.
Preferably, the light transmittance of described first glue-line, described second glue-line and described main film base material reaches more than 90%, and mist degree is less than 2%.
Preferably, the making material of described first glue-line, described second glue-line and described scratch-resistant layer is polyurethane based resin, silicone based resin or acrylic resin.
Preferably, the thick 100um ~ 200um of described main film base material.
Compared with the prior art, the substantive distinguishing features that has of the utility model and marked improvement are:
Mirror surface screen protection film of the present invention is adopted to be convenient to install; and can pass through electrostatic adsorption, fast automatic eliminating bubble, visible light transmissivity is up to 90%; scratch resistance obviously strengthens, and can effectively prevent the article such as finger, suspension member from injuring friction injury to scraping of screen.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 shows the structural representation according to screen protecting film of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 shows the section of structure according to screen protecting film of the present utility model.With reference to Fig. 1, screen protecting film comprises: the first diaphragm 10, first glue-line 20, scratch-resistant layer 30, main film base material 40, polyurethane glue-line 50, second glue-line 60 and the second diaphragm 70.Wherein, the corona surface of main film base material 40 is coated with polyurethane glue-line 50, polyurethane glue-line 50 is coated with again the second glue-line 60, and the non-corona surface of the second glue-line 60 and the second diaphragm 70 fits.The non-corona surface of main film base material 40 is then coated with scratch-resistant layer 30, the corona surface of the first diaphragm 10 is coated with one first glue-line 20, first glue-line 20 and fits with scratch-resistant layer 30 again.In addition, the thickness range of the first diaphragm 10 is 15 ~ 45um, can be 15um, 20um, 25um, 30um or 45um, can certainly be other values within the scope of this.Thickness range 3 ~ the 20um of the first glue-line 20 can be 3um, 7um, 10um, 14um, 17um or 20um, can certainly be other values within the scope of this.The thickness range of scratch-resistant layer 30 is 3 ~ 8um, such as 5um.The thickness of main film base material 40 is 50 ~ 300um, such as 100 ~ 200um, and the thickness range of polyurethane glue-line 50 is 4 ~ 30um, such as 4um, 10um, 15um, 20um, 25um or 30um, can certainly be other values within the scope of this.The thickness range of the second glue-line 60 is 10 ~ 40um, such as 10um, 15um, 20um, 25um30um, 35um or 40um.The thickness range of the second diaphragm 70 is 15 ~ 45um, such as 15um, 25um, 35um or 45um, can certainly be other values within the scope of this.The light transmittance of the first glue-line 20, second glue-line 60 and main film base material 40 can reach more than 90%, and their mist degree is all less than 2%.First glue-line 20, second glue-line 60 and the making material of scratch-resistant layer 30 can be any one in polyurethane based resin, silicone based resin and acrylic resin.
