Description

A kind of OCA optical film
Technical field
The utility model relates to OCA optical cement technical field, refers in particular to a kind of OCA optical film.
Background technology
OCA optical cement be a kind of clean high-clarity without base material double-sided adhesive tape, its properties of transparency is excellent, and transmittance reaches more than 99%; At strong illumination, under hot and humid environment, use also harmless outward appearance; Be applicable to the plastic material pasting polycarbonate etc.; Be mainly used in the stickup between touch-screen (capacitance plate, touch screens) and front panel at present, be widely used in smart mobile phone, handwritten computer, the use of touch screen multimedia machine, there is wide market.
The OCA optical cement layer of OCA optical cement is a kind of transparent colloid of state densification of condensing, current OCA optical cement includes optical cement layer, covers the light release layer on optical cement layer two sides, weighs release layer, OCA optical cement is generally provide with the form of coiled strip when work in-process, according to shape, the specification of produced product, be die-cut into the OCA optical film of required shape by cutting die; Die-cut OCA optical film to be usually placed in box or used for producing after simple packaging, but due to the profile of light release layer, heavy release layer consistent with optical cement layer, therefore when the light release layer be out of shape easy, heavy release layer are subject to External Force Acting a little, easy generation distortion, because optical cement layer belongs to flexible condensation state, when light release layer, heavy release layer edge stress deformation, the as easy as rolling off a log edge of optical cement that causes produces distortion; Thus affect optical cement layer display quality after mounting, reduce quality product, cause substandard products or waste product event to occur.
Utility model content
The utility model is easily to damage the deficiency of existence for current OCA optical film optical cement layer in packaging circular flow, and provides a kind of OCA optical film and production technique thereof that overcome the above problems.
For achieving the above object, the utility model adopts following technical scheme:
A kind of OCA optical film, it is characterized in that, described OCA optical film comprises a heavy release film layer, optical cement layer and a light release film layer successively, and the edge of described heavy release film layer is outwards away from optical cement layer, and described light release film layer covers optical cement layer edge.
Preferably, the distance L at described light release film layer edge and optical cement layer edge, 0.5MM >=L >=1.2MM.
A production technique for above-mentioned OCA optical film, described production technique comprises following processing step:
A, first die-cut: OCA optical cement coiled strip material strip to be carried out Punching Technology, the shape of OCA optical cement layer on demand, cut remaining original light release film layer and OCA optical cement layer;
B, remove original light release film layer: by the original light release film layer of adhesive tape sticky removing above the material strip OCA optical cement layer of steps A;
C, cover light release film layer: a light release film layer coiled strip is set, is covered in by coiled strip above the OCA optical cement layer after step B, forms light release film layer;
D, secondary punch: through the material strip of step C, by the shape of OCA optical cement layer, outwards reserved spacing L cuts light release film layer;
E, cut-out: the heavy release film layer connected between OCA optical cement layer is cut off, forms the OCA optical film of sheet.
The beneficial effects of the utility model are, a kind of OCA optical film of the utility model and production technique thereof, OCA optical film comprises a heavy release film layer, optical cement layer and a light release film layer successively, the edge of described heavy release film layer is outwards away from optical cement layer, and described light release film layer covers optical cement layer edge; The production technique of OCA optical film comprise just die-cut, remove original light release film layer, cover light release film layer, secondary punch, cut-out operation, the edge of the heavy release film layer of OCA optical film is outwards away from optical cement layer, described light release film layer covers optical cement layer edge, therefore be subject in the side, edge of optical cement layer heavy release film layer covering protection, opposite side by the covering protection of light release film layer, the edge deformation of the optical cement layer of condensation state can not be caused when the light release layers of link such as turnover, carrying, heavy release layer edge stress deformation; Ensure optical cement layer display quality after mounting, Improving The Quality of Products, avoid therefore producing substandard products or the generation of waste product event.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Embodiment
Be further elaborated below in conjunction with accompanying drawing 1 pair of the utility model:
A kind of OCA optical film, it is characterized in that, described OCA optical film comprises a heavy release film layer 1, optical cement layer 2 and a light release film layer 3 successively, and the edge of described heavy release film layer 1 is outwards away from optical cement layer 2, and described light release film layer 3 covers optical cement layer 2 edge.
As preferably embodiment, the distance L at light release film layer 3 edge of the present utility model and optical cement layer 2 edge, 0.5MM >=L >=1.2MM.
A production technique for above-mentioned OCA optical film, described production technique comprises following processing step:
A, first die-cut: OCA optical cement coiled strip material strip to be carried out Punching Technology, the shape of OCA optical cement layer 2 on demand, cut remaining original light release film layer and OCA optical cement layer 2;
B, remove original light release film layer: by the original light release film layer of adhesive tape sticky removing above the material strip OCA optical cement layer 2 of steps A;
C, cover light release film layer 3: light release film layer 3 coiled strip is set, is covered in by coiled strip above the OCA optical cement layer 2 after step B, forms light release film layer 3;
D, secondary punch: through the material strip of step C, by the shape of OCA optical cement layer 2, outwards reserved spacing L cuts light release film layer 3;
E, cut-out: cut off by the heavy release film layer 1 connected between OCA optical cement layer 2, form the OCA optical film of sheet.
OCA optical film of the present utility model and production technique thereof, at the edge of heavy release film layer 1 outwards away from optical cement layer 2, described light release film layer 3 covers optical cement layer 2 edge, therefore be subject in the side, edge of optical cement layer 2 heavy release film layer 1 covering protection, opposite side by the covering protection of light release film layer 3, the edge deformation of the optical cement layer 2 of condensation state can not be caused when the light release layer of link, heavy release layer edge stress deformations such as turnover, carryings; Ensure optical cement layer 2 display quality after mounting, Improving The Quality of Products, avoid therefore producing substandard products or the generation of waste product event; Light release film layer 3, heavy release film layer 1 in the art and not exclusive appellation, in a word, are the release films being positioned at optical cement layer 2 both sides, and have employed the appellation in a kind of industry in the utility model for convenience of description.
The above embodiment, just preferred embodiments of the present utility model, be not limit the utility model practical range, therefore all equivalences done according to structure, feature and the principle described in the utility model claim change or modify, and all should be included in the utility model patent claim.
