Description
Technical field
The present invention relates to the sclerosis of a kind of protective membrane and adhesive coating, specifically, be in particular to a kind of toughened glass AB glue with anti-blue light function, belong to adhesive material technical field.
Background technology
Along with society electronic digital product gets more and more; the use of touch-screen is more and more universal; people find the loss of screen very large in routine use; in order to make display screen from the invasion of cut, greasy dirt or prevent the reasons such as reflective, user often selects to stick screen protecting film on a display screen.
The surface hardness of general plastic adhesive film is no more than about 3H, in use easy score protection film, cause changing screen protecting film replacement frequency high, and eyes watch screen attentively for a long time, part " blue light " is comprised in the light sent in screen, can not be absorbed by cornea or lens completely, through retina, retinal function may be caused low, cause visual fatigue, the symptom such as dry and astringent, be exposed to for a long time among this LED blue light light and likely the retina of people caused damage, macular degeneration odds increases to two times of mobile phone screen toughened glass screening glass, and due to it, to have resistance to marring good, the high-qualitys such as transparency is high and reliably performance and be subject to the favor of vast mobile phone manufacturing firm.
Toughened glass also has its shortcoming: seem thicker compared with other films, also affects the susceptibility of touch-screen simultaneously, and because toughened glass is hard also crisp, general performance is frangible.Although toughened glass intensity is stronger than simple glass, toughened glass has the possibility of self-destruction (oneself breaks), and simple glass does not exist the possibility of self-destruction.
Only toughened glass can not be attached together with screen, and does not possess anti-blue light function.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art; a kind of toughened glass film AB glue and the preparation method with anti-blue light function are provided; based on the PET through anti-blue light process; one side is silica gel; one side is that special double faced adhesive tape protected by the toughened glass of the tackiness agent of high cohesion; wherein silica gel (automatic vent) fits in mobile phone, and the tackiness agent of high cohesion fits in glass.Adopt coating process, protecting against shock process, high rigidity process is done on surface, can reach 5H, effectively prevents the scratch of LCD screen.
For achieving the above object, the present invention adopts following scheme:
There is a toughened glass film AB glue for anti-blue light function, include PET polyester film base material, introduce UV acrylate resin layer on PET polyester film base material, introduce adhering agent layer on UV acrylate resin layer, on adhering agent layer, introduce release film; PET polyester film base material have layer of silica gel, layer of silica gel have PET peel ply.
Wherein in some embodiments, described UV acrylate resin layer (anti-blue light UV glue) selects vinylformic acid photocuring system, and UV lamp energy is at 30 ~ 200mj/cm
2scope in.
