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.

Preferably, it is characterised in that the baking in the step C and the step H is carried out in baking box.
Preferably, step K is also included after the step D and before the step E：Winding behaviour is carried out to product
Make.
The beneficial effects of the present invention are：Said structure can make rupture pressure disc with specific design and color, can also enter
The cost of one step reduction rupture pressure disc, improves manufacture efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of rupture pressure disc of the present invention；
Fig. 2 is the flow chart of explosion-proof film manufacturing method of the present invention.
Specific embodiment
The present invention 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 sub- quick glue-line 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 present invention also provides the manufacture method of above-mentioned rupture pressure disc, the manufacture method is comprised the following steps：
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,
Sub- quick glue-line 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 invention；
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 sub- quick glue-line 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 invention not limit practical range of the invention, thus it is all according to
The equivalent change or modification that construction, feature and principle described in scope of the present invention patent are done, all should be included in the present invention
In patent claim.
