Abstract
The utility model discloses an OCA piece. The OCA piece is composed of a light release film layer, an OCA layer and a heavy release film layer. When the OCA piece is used, just the light release film layer needs to be torn, OCA adheres to a corresponding adhering object in an alignment mode, then the heavy release film layer is torn, and finally attaching is carried out. The OCA piece is finished through the punching process and is simple in structural design, convenient to use and practical, and the fault rate in the use process is lowered.
Description
Technical field
The utility model relates to optical lens gelatin technical field.
Background technology
Optical lens gelatin (be Optically Clear Adhesive, be called for short OCA glue) has advantages of homogeneous, specific refractory power is consistent, light transmission good, stickiness is good etc.The OCA glue of different thickness can be applicable to different fields, and its main application is: the laminating of indicating meter assembling, lens assembling, touch-screen, panel, glass and plastic material.In the optical lens gelatin use procedure of prior art, inconvenient owing to using, spoilage is higher, causes the wasting of resources.
The utility model content
The problem that the utility model solves is to provide a kind of OCA film, solves OCA glue inconvenient problem with use.
In order to address the above problem, the technical solution adopted in the utility model is:
The utility model provides a kind of OCA film, and it is divided into three layers, is followed successively by light release film layer, OCA glue-line and heavy release film layer.Described light release film and heavy release film are that (surface is through plasma treatment for two kinds of different release films of off-type force (tearing the needed pulling force of the release film be attached on viscose glue), or be coated with fluorine and process, or be coated with the silicon parting agent and there is plastics film separatory).
Further, the light release film layer edge of described OCA film exceeds OCA glue-line edge, is not less than 1mm.
Further, the heavy release film layer of described OCA film, be provided with tear-off portion, and described tear-off portion exceeds described OCA glue-line edge.
Further, the off-type force ratio of the off-type force of the light release film of described OCA film and heavy release film is less than 1: 2.5.
Further, described tear-off portion is 2 places, is positioned at two diagonal angles of described heavy release film layer.
Compared with prior art, the advantage of technical solutions of the utility model is:
The light release film layer edge of OCA film described in the utility model exceeds OCA glue-line edge, is not less than 1mm, during use, is easy to light release film is torn, and then the alignment of OCA glue-line is attached on corresponding bonding object; By tear-off portion, easily heavy release film is torn again, then the miscellaneous part of fitting.The structure design of the utility model OCA film is simple, easy to use, reduced the spoilage in the use procedure, in addition, the utility model OCA film has the characteristics such as high clarity, high light transmittance, high adhesion force, high-weatherability, has significantly improved sense of worth and the usability of electronic accessory parts.In a word, OCA film described in the utility model has easy to use, stickiness and reaches well the advantages such as high light transmittance.
The accompanying drawing explanation
Fig. 1 is specific embodiment of the utility model one-piece construction schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Shown in Fig. 1, a kind of OCA film, described OCA film is superposeed and forms successively by light release film 1, OCA glue-line 2 and heavy release film layer 3.Because the edge of described light release film layer 1 exceeds OCA glue-line 2 edges, convenient a light release film 1 is torn; Be provided with tear-off portion 31 on two diagonal angles of described heavy release film layer 3, tear-off portion 31 exceeds described OCA glue-line 2 edges, and described tear-off portion 31 is convenient to tear heavy release film layer 3.As can be seen here, while using the utility model OCA film, very convenient, reduced the spoilage in the use procedure, avoid the wasting of resources.
Certainly, described OCA glue, according to actual needs, can also increase other retes, such as the transparent PET rete, to improve the defencive function of OCA glue.
The light release film layer edge of OCA film described in the utility model exceeds OCA glue-line edge, during use, is easy to light release film is torn, and then the alignment of OCA glue-line is attached on corresponding bonding object; By tear-off portion, easily heavy release film is torn again, then the miscellaneous part of fitting.The structure design of the utility model OCA film is simple, easy to use, reduced the spoilage in the use procedure, in addition, the utility model OCA film has the characteristics such as high clarity, high light transmittance, high adhesion force, high-weatherability, has significantly improved sense of worth and the usability of electronic accessory parts.In a word, OCA film described in the utility model has easy to use, stickiness and reaches well the advantages such as high light transmittance.
Although the utility model with better enforcement openly as above; but it is not for limiting the utility model; any those skilled in the art are not within breaking away from spirit and scope of the present utility model; can make possible change and modification, the scope that therefore protection domain of the present utility model should be defined with the utility model claim is as the criterion.
Claims (5)
1. an OCA film, is characterized in that, described OCA film is formed by stacking successively by light release film layer, OCA glue-line and heavy release film layer.
2. OCA film according to claim 1, is characterized in that, described light release film layer edge exceeds OCA glue-line edge, is not less than 1mm.
3. OCA film according to claim 1, is characterized in that, described heavy release film layer, be provided with tear-off portion, and described tear-off portion exceeds described OCA glue-line edge.
4. OCA film according to claim 1, is characterized in that, the off-type force ratio of the off-type force of described light release film and heavy release film is less than 1: 2.5.
5. OCA glue according to claim 3, is characterized in that, described tear-off portion is 2 places, is positioned at two diagonal angles of described heavy release film layer.
