Abstract
The utility model discloses a OCA optical cement, be equipped with gently from type membrane, optics glued membrane, heavily leave type membrane and protection film in proper order including from the top down, the protection film upper surface is equipped with the adhesion and glues, and the protection film is laminated in heavily leaving type membrane lower surface through adhesion glue. The utility model discloses simple structure is through heavily sticking the protection film from the back of type membrane man -hour adding to be greater than optics glued membrane itself, gently strengthen simultaneously from the type membrane the optical cement is epimembranal simultaneously, also be greater than optics glued membrane itself, can guarantee can not receive the pollution of foreign matter processing under the environment optics glued membrane edge.
Description
Technical field
This utility model relates to OCA optical cement technical field, particularly relates to a kind of OCA optical cement.
Background technology
Chinese Patent Application No.: 201520791268.1, discloses a kind of OCA with anti-electromagnetic wave effect
Optical adhesive film, including the heavy mould release membrance set gradually from top to bottom, anti-electromagnetic wave height mucigel, layer of silica gel and
Middle mould release membrance, the upper surface of anti-electromagnetic wave height mucigel, lower surface respectively with weight the lower surface of mould release membrance, silicon
The upper surface laminating of glue-line, the upper surface laminating of the lower surface of layer of silica gel and middle mould release membrance.
Chinese Patent Application No.: 201420663188.3, discloses a kind of OCA optical film, refers in particular to
A kind of OCA optical film；The edge of OCA optical cement tablet weight release film layer is outwardly away from optical cement layer, described gently
Release film layer covers optical cement layer edge；The production technology of OCA optical film include just the most die-cut, go original gently from
Type film layer, cover light release film layer, secondary punch, cut-out operation, the heavy release film layer of OCA optical film
Edge is outwardly away from optical cement layer, and described light release film layer covers optical cement layer edge.
Above-mentioned utility model structure is complicated, easily by foreign substance pollution in processing and transportation, causes product
Bad.
Utility model content
The purpose of this utility model is, overcomes the drawbacks described above of prior art, it is provided that a kind of OCA optical cement.
For achieving the above object, the technical scheme that this utility model provides is as follows: a kind of OCA optical cement, bag
Include and be sequentially provided with light mould release membrance, optical adhesive film, weight mould release membrance and protecting film from top to bottom, on described protecting film
Surface is provided with adhesion glue, and protecting film passes through adhesion sticker together in weight mould release membrance lower surface.
Wherein, light mould release membrance width is more than optical adhesive film width 2 to 4mm, and light mould release membrance length is more than optics
Glued membrane length 6 to 10mm.
Wherein, weight mould release membrance length and width are consistent with optical adhesive film length and width.
Wherein, protecting film width is more than light mould release membrance width 3 to 5mm, and protecting film length is long with light mould release membrance
Degree is consistent.
Wherein, light mould release membrance and protecting film thickness are 0.05mm.
Of the present utility model have the beneficial effect that by add man-hour weight mould release membrance the back side stick protecting film,
And more than optical adhesive film itself, the light mould release membrance on optical adhesive film is strengthened, also greater than optical cement simultaneously simultaneously
Film itself, it can be ensured that optical adhesive film edge will not be polluted by foreign body under processing environment.
Accompanying drawing explanation
Fig. 1 is the schematic top plan view of this utility model a kind of OCA optical cement；
Fig. 2 is the schematic side view of this utility model a kind of OCA optical cement；
Detailed description of the invention
Below in conjunction with the accompanying drawings and preferred embodiment is further described with regard to the technical solution of the utility model.
As Figure 1-Figure 2, a kind of OCA optical cement described in the utility model, including the most successively
Arrange light mould release membrance 2, optical adhesive film 1, weight mould release membrance 4 and protecting film 3, optical adhesive film 1 upper surface with
Light mould release membrance 2 lower surface laminating, optical adhesive film 1 lower surface and the laminating of weight mould release membrance 4 upper surface, protecting film 3
Upper surface is provided with adhesion glue (not shown), and protecting film 3 is by adhesion glue laminating and weight mould release membrance 4 following table
Face.
Further, light mould release membrance 2 width is more than optical adhesive film 1 width 2 to 4mm, and light mould release membrance 2 is long
Degree is more than optical adhesive film 1 length 6 to 10mm.
Further, weight mould release membrance 4 length and width are consistent with optical cement 1 length and width.
Further, protecting film 3 width be more than light mould release membrance 2 width 3 to 5mm, protecting film 3 length with
Light mould release membrance 2 length is consistent.
Further, light mould release membrance 2 and protecting film 3 thickness are 0.05mm.
Above, by sticking protecting film 3 adding the back side at weight mould release membrance 4 in the man-hour, and more than optical adhesive film 1
Itself, strengthen the light mould release membrance 2 on optical adhesive film 1 simultaneously simultaneously, also greater than optical adhesive film 1 itself,
May insure that optical adhesive film edge will not be polluted by foreign body under processing environment.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that, this area
For those of ordinary skill, on the premise of without departing from this utility model principle, moreover it is possible to make some modification
And improvement, also should be regarded as belonging to protection domain of the present utility model.
