Description
Technical field
The utility model is related to a kind of rupture pressure disc of colour, more particularly to is a kind of the colored explosion-proof of use for electronic products
Film.
Background technology
In recent years, with the popularization of smart mobile phone and other smart electronicses products, more and more electronics with touch-screen
Product can use rupture pressure disc.Rupture pressure disc is a kind of a kind of PC plastic cement for being attached to and sticking on electric capacity panel glass.Can effectively buffer and hit
Hitting, prevent screen from bursting, or prevent electronic product from clashing into accidentally causes the broken of glass panel to disperse, and reduces the hidden of glass panel
Property injury, ensure user security；The distinctive gloss of strengthened glass, texture and raising case hardness can also be maintained.
Chinese patent CN203472238U discloses a kind of external decoration rupture pressure disc, and the rupture pressure disc is solved by adding decorative layer
The display screen of existing electronic product of having determined lacks the problem of color and change in pattern.
Due to the decorative layer be located between PET basic units and glue-line, in order to prevent in the manufacturing process of glue-line, glue-line into
Divide and corrosion is caused to decorative layer, therefore the rupture pressure disc employs the OCA glue of solid-state, OCA glue is double faced adhesive tape, is directly fitted in basic unit
On, will not be chemically reacted with basic unit, therefore corrosion will not be caused to decorative layer.
However, OCA glue material cost in itself is higher, and solid-state OCA glue-lines in cutting, be easily adhered in cutter
On, it is therefore desirable to the cutting technique for becoming more meticulous very much, it is to avoid adhesion, and manufacture efficiency is low, so as to increased rupture pressure disc entirety
Manufacturing cost.
Utility model content
A kind of colored rupture pressure disc that the utility model is provided to solve the above problems, the colored rupture pressure disc according to
It is secondary including：Protection film layer, printing layer, PET basic units, pressure-sensitive adhesive layer and release film layer, the PET basic units contact with the printing layer
Surface there is hardened layer, the printing layer is ink, and the pressure-sensitive adhesive layer is solvent-borne type glue-line.
Preferably, the pressure-sensitive adhesive layer is acrylic glue-line or layer of silica gel.
Preferably, the thickness sum scope of the printing layer, the PET basic units and the pressure-sensitive adhesive layer is 0.13-
0.17mm, the thickness range of the protection film layer is 0.03-0.05mm, and the thickness range of the release film layer is 0.04-
0.06mm。
The beneficial effects of the utility model are：Said structure can make rupture pressure disc with specific design and color,
The cost of rupture pressure disc can be further reduced, manufacture efficiency is improved.
Brief description of the drawings
The structural representation of the rupture pressure disc that Fig. 1 is related to for the utility model；
The flow chart of the explosion-proof film manufacturing method that Fig. 2 is related to for the utility model.
Specific embodiment
The utility model is further elaborated below in conjunction with the accompanying drawings：
As shown in figure 1, the rupture pressure disc of colour includes successively：Protection film layer 1, printing layer 2, PET basic units 3, the He of pressure-sensitive adhesive layer 4
Release film layer 5.The surface that PET basic units 3 contact with printing layer 2 has hardened layer, and the hardened layer is by the table to PET basic units 3
Face carries out cure process formation.In the present embodiment, printing layer 2 is ink；Pressure-sensitive adhesive layer 4 is solvent-borne type glue-line, solvent-borne type
Glue-line refers to that, when gluing is operated, the glue-line is liquid.More specifically, the pressure-sensitive adhesive layer 4 is acrylic glue-line or layer of silica gel.Its
In, the thickness sum scope of printing layer 2, PET basic units 3 and pressure-sensitive adhesive layer 4 is 0.13-0.17mm, the thickness range of protection film layer 1
It is 0.03-0.05mm, the thickness range of release film layer 5 is 0.04-0.06mm.
Because printing layer 2 is located on a surface of PET basic units 3, pressure-sensitive adhesive layer 4 is located at another surface of PET basic units 3
On, therefore, even if using lower-cost solvent-borne type glue-line, in the manufacturing process of pressure-sensitive adhesive layer 4, its composition also will not be to printing
Layer 2 is damaged.It can be seen that, said structure can make rupture pressure disc with specific design and color, also can further reduce explosion-proof
The cost of film, improves manufacture efficiency.
As shown in Fig. 2 the utility model also provides the manufacture method of above-mentioned rupture pressure disc, the manufacture method includes following step
Suddenly：
Step one S1, two surfaces to PET basic units 3 carry out sided corona treatment, and the surface of PET basic units 3 is produced under high-tension current
Raw polarity, to increase the roughness and surface energy of film surface, improves the adhesive force on the surface of film PET basic units 3；
Step 2 S2, on one of surface of PET basic units 3 apply pressure sensitive adhesive；
Step 3 S3, product is toasted, the temperature range of baking is 50-140 DEG C, and baking time is more than 1min,
Pressure-sensitive adhesive layer 4 is formed, in the present embodiment, PET basic units 3 are put into baking oven and are toasted；
Step 4 S4, the surface for the scribbling pressure-sensitive adhesive layer 4 laminating release film layer 5 in PET basic units 3, release film layer 5 are used to protect
Shield pressure-sensitive adhesive layer 4；
Step 5 S5, wind-up operation is carried out to product；
Step 6 S6, maturation process is carried out to product, the temperature range of curing is 40-60 DEG C, and the curing time is 70h, is protected
Curing agent reaction in card pressure-sensitive adhesive layer 4 is complete, improves the tack stability of glue-line；
Another surface of step 7 S7, another surface painting hardening bath in PET basic units 3, hardening bath and PET basic units 3
Reaction；
Step 8 S8, product is toasted, the temperature range of baking is 50-140 DEG C, for above-mentioned reaction is provided suitably
Environment；
Step 9 S9, ultra-violet curing is carried out to product, make the reacted thing in another surface of hardening bath and PET basic units 3
Matter forms hardened layer；
Step 10 S10, printed on hardened layer using ink, formed printing layer 2；
Step 11 S11, protection film layer 1 of being fitted in printing layer, for protecting printing layer 2 and PET basic units 3, form this
The rupture pressure disc of utility model；
Step 12 S12, wind-up operation is carried out to product.
After tested, the adhesion strength of pressure-sensitive adhesive layer 4 is 1500gf//more than 25mm, and the adhesion strength scope of protection film layer 1 is 4-
6gf//25mm.The tensile strength of rupture pressure disc is more than 200MPa.
In wearability test, in the load of 1000g, rubbing surface is 2cm × 2cm, water droplet angle >=90 ° after friction to rupture pressure disc
Under the conditions of, steel wool Rubbing number is up to 1000 times.Additionally, the hardness of rupture pressure disc is 2H.
Because coating technique and typography are carried out in two different surfaces of PET basic units, therefore coating technique will not be right
Printing layer causes to damage, and pressure-sensitive adhesive layer can be with the relatively low solvent-borne type glue-line of alternative costs, and the mistake cut in follow-up rupture pressure disc
Cheng Zhong, there will not be the problem that glue-line is attached to above cutter.
Embodiment described above, simply preferred embodiments of the present utility model not limit implementation model of the present utility model
Enclose, therefore the equivalent change or modification that all constructions according to described in present utility model application the scope of the claims, feature and principle are done, all should
It is included in the utility model patent claim.
