Description
Technical field
The present invention relates to safeguard film for cellular phone technical field, espespecially a kind of bend glass screen protection cuticula is integrally formed processing work
Skill and its diaphragm.
Background technology
Sticking film for mobile phone is also known as mobile phone cosmetic membrane, safeguard film for cellular phone, is one kind available for mounting handset, protection screen
Cold lamination film.It can be divided into according to its purposes：Protecting film of mobile phone screen, handset diaphragm, peep-proof film, mirror film, AR films, frosted
Film, scratch resistant diaphragm, handset anti-scratch diaphragm, handset decoration diaphragm；Existing market main flow is PET material
Diaphragm and glass protection film.But because the update of present electronic product is fast, also there occurs very big change for outward appearance.
The many products in present market are all cambered surface screens, and from 2.5D to 3D, this is also development trend.Common safety glass
Film can only paste front and plane, can not be played a very good protection for bent portion.In order to solve this problem, permitted before
Voluminous family is compounded in the two sides of PET film by the way that organosilicon and acrylic glue are respectively coated, and heating vulcanization forms double faced adhesive tape, then passes through
The size that die-cutting process cuts into Mobile phone screen is crossed, is then fitted on glass, glass is finally adsorbed onto Mobile phone screen again, effect is not
Ideal, the easy alice of cambered surface edge and corrugation, and bubble and snow etc. are fitted with, fraction defective is too high, as shown in Figure 1.
The content of the invention
To solve the above problems, a kind of bend glass screen protection cuticula of present invention offer is integrally formed processing technology and its guarantor
Cuticula, the display screen of digital product play more preferable, more fully protective effect, especially for the product of Curved screen, improve existing
There is technique very complicated, fitting size has the problems such as deviation, improves product yield.
To achieve the above object, the technical solution adopted by the present invention is：A kind of bend glass screen protection cuticula is integrally formed
Processing technology, comprise the following steps：
S1:Bend glass screen is placed in the die cavity of injection machine mould, in the table that bend glass screen contacts with display screen
Leave space in face；
S2：By liquid injection agent toward cavity injection from no-solvent type organic pressure-sensitive gel is adsorbed, make solvent-free from adsorbing
Type organic pressure-sensitive gel is sufficient filling with the one side of the space parcel covering surface glass screen contact display screen in die cavity, forms self-priming
Attached no-solvent type silicone pressure sensitive glue-line；
S3：By bend glass screen and absorption no-solvent type organic pressure-sensitive gel sulfidization molding certainly；
S4：The finished product of shaping is taken out in die sinking, is cooled to normal temperature.
Further, in step S1, the thickness in the space that surface that bend glass screen contacts with display screen is left is 50-
150um。
Further, in step S3, the temperature of sulfidization molding is 130 DEG C, time 35s.
Further, the brookfield viscosity from absorption no-solvent type organic pressure-sensitive gel is 1000-20000cps.
Further, the shore hardness from absorption no-solvent type organic pressure-sensitive gel is less than 10A.
Further, the no-solvent type organic pressure-sensitive gel of absorption certainly is Silica hydrogel.
To achieve the above object, another technical scheme for using of the present invention is：A kind of bend glass screen protection cuticula, including song
Surface glass screen and certainly absorption no-solvent type silicone pressure sensitive glue-line, the sides of two lateral contact display screens of the bend glass screen
Bending, it is described from absorption no-solvent type silicone pressure sensitive glue-line be arranged on bend glass screen contact display screen side, and with song
Surface glass screen is integrally formed.
Further, the brookfield viscosity from absorption no-solvent type silicone pressure sensitive glue-line is 1000-
20000cps。
Further, the shore hardness from absorption no-solvent type silicone pressure sensitive glue-line is less than 10A.
Further, the no-solvent type organic pressure-sensitive gel of absorption certainly is Silica hydrogel.
The beneficial effects of the present invention are：The present invention will be by that will adsorb no-solvent type organic pressure-sensitive gel and bend glass certainly
After integrated vulcanizing shaping, reduce the coating process in existing process, largely using manpower and material resources sparingly can guarantee that even in glass
After in uneven thickness or hot bending size not accurately in the case of, still can contact the self-priming of display screen to the fitting of screen 100%
The surface of the no-solvent type organic pressure-sensitive gel of attached function with the size 100% of screen due to coincideing, so being bonded when applying
Defect rate is extremely low, while using from absorption no-solvent type organic pressure-sensitive gel, reduces the pollution and waste to environment, more meet ring
Guaranteed request and cost savings.
Brief description of the drawings
Fig. 1 is the packaging technology structural representation of existing bend glass screen protection cuticula；
Fig. 2 is the structural representation of the present invention.
Embodiment
Below by specific embodiment, the present invention is further illustrated.
