Description
Technical field
The present invention relates to after PET film technical field more particularly to PET rupture pressure disc, implosion guard rear cover and implosion guard
The preparation process of lid.
Background technique
Nowadays many high-end handsets all have begun the rear cover using glass material, in order to improve visual effect and mobile phone
Feel, 3D glass covers after being widely used in mobile phone glass.
The cell phone rear cover as made from 3D glass is due to cambered, processing difficulties, and the presence of stress, which allows, after molding falls broken screen
And it generates a possibility that glass fragment splashes and increases.
In order to improve the visual effect of mobile phone, need in the enterprising luggage decorations of glass back cover.But since glass hardness itself is high,
Glass transition temperature and surface can be very low, and inorganic material has good chemically-resistant, make to decorate in glass back cover
It is extremely difficult.
Existing decoration technique is usually glass back cover to be electroplated, and then obtain the metal effect dazzled very much.But
It is electroplated on glass, efficiency and yield are low.And electroplated layer is easy to oxidize, can be changed colour using rear glass back cover for a long time, shadow
It rings beautiful.And the electroplated layer with metal can generate electromagnetic shielding, lead to mobile phone signal difference and cannot achieve wireless charging electric work
Energy.
The blue Light Film that the PICASUS film and SKC company, South Korea that toray company (TORAY) releases are released can generate
Metallic luster is but without metal component.
Summary of the invention
The technical problem to be solved by the present invention is to according to above-mentioned the deficiencies in the prior art, provide a kind of PET rupture pressure disc, explosion-proof
The preparation process of glass back cover and implosion guard rear cover, and then splashing glass when preventing mobile phone glass rear cover broken, are realizing gold
Since oxidation stain and electromagnetic shielding phenomenon will not occur without metal component while belonging to effect.
Technical scheme is as follows:
PET rupture pressure disc includes the OCA optical adhesive layer being bonded up and down, metallic luster PET base, UV transfer glue-line and printing
Layer；OCA optical adhesive layer is with a thickness of 20-30um；Metallic luster PET base is PICASUS film or the SKC company of TORAY company
Blue Light Film, with a thickness of 30-145um.
Implosion guard rear cover includes glass cover-plate and PET rupture pressure disc as described above；Glass cover-plate fits in OCA optics
Glue-line upper surface.
Further, the glass cover-plate is 3D glass cover-plate.
The preparation process of implosion guard rear cover as described above, step includes: a. passes through UV transfer printing process for UV transfer glue
Layer fits in metallic luster PET base lower surface；B. printing layer is formed in UV transfer glue-line lower surface coloring grounding；C. in volume pair
It rolls up on make-up machine, after the light release film in OCA optical adhesive layer is removed by waste discharge roller, OCA optical adhesive layer is fitted in metal light
Damp PET base upper surface, and obtain PET rupture pressure disc；D. PET rupture pressure disc is die cut；E. at full-automatic to a make-up machine
On PET rupture pressure disc and glass cover-plate are bonded, then carry out deaeration processing, obtain implosion guard rear cover.
Compared with prior art, the invention has the following beneficial effects:
(1) PET rupture pressure disc fits in glass cover-plate, splashing glass when preventing mobile phone glass rear cover broken；It is particularly suitable for stress
Biggish 3D glass back cover.
(2) metallic luster PET base can assign PET rupture pressure disc and implosion guard rear cover metallic luster, and be free of metal
Ingredient, because without oxidation stain and electromagnetic shielding phenomenon occurs, mobile phone signal will not be shielded, and nothing may be implemented in mobile phone
Line charge Electricity Functional.
(3) UV, which transfers glue-line, can assign the lines of PET rupture pressure disc and implosion guard rear cover all styles of, and such as CD line is drawn
Silking, batch decorative pattern, sandblasting line etc.；Printing layer can assign PET rupture pressure disc and implosion guard rear cover metal background color.
(4) fitting that glue-line and printing layer are transferred by metallic luster PET base, UV assigns PET rupture pressure disc and explosion-proof
Glass back cover metal effect, this does that electroplated decoration effect is more efficient, and at low cost and effect is more than covering after mobile phone glass
It is good.
(5) OCA optical adhesive layer is pasted using roll-to-roll make-up machine, avoids metallic luster PET base since the material is soft,
Metallic luster PET substrate surface the problem of there may be orange peels during applying OCA optical adhesive layer and influence appearance, efficiency is good
Rate is high, and cost is lower.

Fig. 1 is the sectional view of first embodiment.
Fig. 2 is the sectional view of second embodiment.
Appended drawing reference
1-OCA optical adhesive layer, 2- metallic luster PET base, 3-UV transfer glue-line, 4- printing layer, 5- glass cover-plate.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
Step ground detailed description.
As shown in Figure 1, first embodiment provided by the invention, PET rupture pressure disc, include the OCA optical cement being bonded up and down
Layer 1, metallic luster PET base 2, UV transfer glue-line 3 and printing layer 4.OCA optical adhesive layer 1 is with a thickness of 20-30um；Metal light
Damp PET base 2 is the PICASUS film of TORAY company or the blue Light Film of SKC company, with a thickness of 30-145um.Wherein first implements
In example preferably, OCA optical adhesive layer 1 is with a thickness of 25um, and metallic luster PET base 2 is PICASUS film, with a thickness of 70um.
As shown in Fig. 2, second embodiment provided by the invention, implosion guard rear cover, include glass cover-plate 5 and such as first
