Abstract
The utility model discloses optical transparent double-faced adhesive tape. The double-faced adhesive tape is divided into three OCA (Optical Clear Adhesive) layers, a transparent substrate layer and an OCA layer in sequence, wherein the transparent substrate layer is formed by a PET (Polyethylene Terephthalate) material, a PC (Poly Carbonate) material or a PMMA (Polymethyl Methacrylate) material; the thickness of the OCA layers is not larger than 0.6 mm; and the thickness of the transparent substrate is not larger than 2.0 mm. The optical transparent double-faced adhesive tape can be easily made to be thick, the thickness range of the optical transparent double-faced adhesive tape is wider due to the adoption of the three-layer structure, and the whole thickness can be realized by adjusting the thickness of the OCA layers at two sides and the transparent substrate layer in the middle; the wide thickness range can be realized by adopting a solvent method or a solvent-free method; and the die cutting performance is good, since the transparent substrate layer is separated between the OCA layers, the yield during the die cutting process can be effectively improved, and the cost of a single optical and transparent double-faced adhesive tape is reduced.
Description
Technical field
The utility model relates to a kind of optical cement, particularly relates to a kind of optical clear double sticky tape that is applied to the touch-screen field.
Background technology
The optical lens gelatin, promptly the OCA optical cement is the good transparent film structure of a kind of light transmission, it also is to be applied to one of main optics in the capacitive touch screen.The capacitive touch screen of prior art will reach relatively difficulty of bubble-free laminating in making processes, therefore need to adopt the optical lens gelatin of thick type could obtain acceptable good article rate.General 5 inches is the optical lens gelatin of 0.175mm-0.2mm with interior capacitive touch screen used thickness, and the capacitive touch screen used thickness more than 5 inches is the optical lens gelatin of 0.25mm-0.35mm.Optical lens gelatin of the prior art mainly is that the form with pure glued membrane exists, though it has material homogeneous, specific refractory power is consistent, filling properties is good advantage, but following 2 deficiencies is arranged: (1) optical lens gelatin of the prior art; Its starting material are made difficulty, if with the solvent method coating, be difficult to do thick; And easy xanthochromia; Influence the quality of capacitive touch screen, if use solvent-free method of manufacture, producing apparatus and environmental requirement are higher; The domestic existing working condition of China can not satisfy, and has upper thickness limit and the low problem of good article rate; (2) die-cutting performance of the optical lens gelatin of prior art is bad, in the course of processing, is difficult for waste discharge, and good article rate is lower, thereby causes the cost of monolithic optical transparent adhesive tape higher.
The utility model content
To deficiency of the prior art, the utility model provides a kind of optical clear double sticky tape, and the optical lens gelatin is difficult to do the problem thick, that die-cutting performance is bad in the prior art to solve.
For solving the problems of the technologies described above, the utility model provides a kind of optical clear double sticky tape, and it is divided into three layers, is followed successively by OCA optics glue-line, transparent substrate layer and OCA optics glue-line.
Through the optical clear double sticky tape is designed to three-decker; Transparent substrate is adopted in the middle layer; The OCA optical cement is adopted on the two sides of transparent substrate; The thickness of whole like this optical clear double sticky tape can be adjusted through the thickness of adjustment OCA optical cement or transparent substrate, thereby has solved the problem that thick type optical clear double sticky tape is made difficulty; The transparent substrate that increases makes the centre of OCA optical cement have one deck base material to intercept, thereby can effectively improve the good article rate in the cross cutting process, has also reduced the cost of the transparent double sticky tape of monolithic optical virtually.
Said transparent substrate layer is PET material, PC material or PMMA material.These three kinds of materials are the optical grade film materials with film forming properties, and its general character is that specific refractory power approaches the optical lens gelatin, has certain ageing-resistant performance.
The thickness of said OCA optics glue-line is not more than 0.6mm.What this thickness range can cover the touch-screen industry fully uses the glue demand.
The thickness of said transparent substrate layer is not more than 2.0mm.If the thickness of transparent substrate layer surpasses 2.0mm, common cutting die is difficult to its cut-out is unfavorable for die-cutting production.
The utlity model has following useful technique effect:
(1) the optical clear double sticky tape can be easy to do thick, and the design of three-decker makes its thickness range more wide in range, and whole thickness can be reached through the OCA optics glue-line on adjustment both sides and the thickness of intermediary transparent substrate layer; No matter be to adopt solvent method or adopt solventless method all can realize wide in range thickness range.
(2) die-cutting performance is good, owing to there is the layer of transparent base material to intercept in the middle of the OCA optical cement, so can effectively improve the good article rate in the cross cutting process, has reduced the cost of the transparent double sticky tape of monolithic optical.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model optical clear double sticky tape;
Among the figure: 1-OCA optics glue-line, 2-transparent substrate layer.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
As shown in Figure 1, a kind of optical clear double sticky tape, it is divided into three layers, is followed successively by OCA optics glue-line 1, transparent substrate layer 2 and OCA optics glue-line 1, can OCA optics glue-line 1 be coated the surface of said transparent substrate layer 2 through coating process.Said transparent substrate layer 2 is PET material, PC material or PMMA material.The thickness of said OCA optics glue-line 1 is not more than 0.6mm, can carry out the adjustment of concrete numerical value according to concrete production requirement.The thickness of said transparent substrate layer 2 is not more than 2.0mm, can carry out the adjustment of concrete numerical value according to concrete production requirement.
Present embodiment is designed to three-decker with the optical clear double sticky tape; Transparent substrate is adopted in the middle layer; The OCA optical cement is adopted on the two sides of transparent substrate, and the thickness of whole like this optical clear double sticky tape can be adjusted through the thickness of adjustment OCA optical cement or transparent substrate.The transparent substrate that increases makes the centre of OCA optical cement have one deck base material to intercept, thereby can effectively improve the good article rate in the cross cutting process.
Above-listed detailed description is specifying to one of the utility model possible embodiments; This embodiment is not the claim in order to restriction the utility model; Allly do not break away from the equivalence that the utility model does and implement or change, all should be contained in the claim of this case.
