Abstract
The utility model provides an optical clear adhesive (OCA) tape for a capacitive touch screen. The OCA tape comprises a clear substrate, OCA layers, a PET (polyethylene terephthalate) heavy film and a PET light film, wherein the OCA layers are arranged on the two sides of the clear substrate respectively; the clear substrate and the OCA layers form the OCA tape; the PET heavy film is arranged on one side of the OCA tape; and the PET light film is arranged on the other side of the OCA tape. The OCA tape has the advantages that during die cutting, the foam cut end is smooth and clean, the die cutting property is good and the OCA frame is free from excessive adhesives; the OCA tape greatly improves the optical and mechanical properties of the capacitive touch screen and can well reduce diffuse reflection of light, eliminate the phenomenon that the screen is pressed and generates water streaks, enhance the water resistance of the capacitive touch screen and prolong the life of the capacitive touch screen; the thickness of the optical clear double-sided adhesive tapes can be adjusted by adjusting the thickness of the OCA or the clear substrate, thus solving the problem that the thick optical clear double-sided adhesive tapes are difficult to manufacture; and the OCA tape is low in cost, is easy to implement and has a good implementation effect.
Description
Technical field
The utility model relates to a kind of optical cement, especially relates to a kind of optical clear adhesive tape for capacitance touch screen.
Background technology
The optical lens gelatin, it is the OCA optical cement, it is the good transparent film structure of a kind of light transmission, as the special adhesive that is used for glued transparent optical element, have water white transparency, light transmission rate more than 98%, consolidation strength is good, can solidify under room temperature or middle temperature, and characteristics such as cure shrinkage is little are arranged, 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.Optical lens gelatin of the prior art mainly is that the form with pure glued membrane exists, and its starting material are made difficulty, and have upper thickness limit and the low problem of good article rate; The die-cutting performance of optical lens gelatin is bad, and overflow glue and bubble appear in product frame easily, in the course of processing, are difficult for waste discharge, and good article rate is lower, thereby causes the cost of monolithic optical transparent adhesive tape higher.
Summary of the invention
The utility model purpose provides a kind of optical clear adhesive tape for capacitance touch screen.The existing in prior technology die-cutting performance is poor to solve, the technical problems such as glue, bubble of overflowing appear in optical cement frame easily.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of optical clear adhesive tape for capacitance touch screen, comprise transparent substrate, OCA optics glue-line, the heavy film of PET, the light film of PET, described transparent substrate two sides is respectively equipped with OCA optics glue-line, and this transparent substrate and OCA optics glue-line are formed the transparent optical adhesive tape; Described transparent optical adhesive tape simultaneously is provided with the heavy film of PET, and another side is provided with the light film of PET.
As preferably, the transparent optical adhesive tape is provided with on the light face of PET by special moulding machine hemisection, makes its transparent optical adhesive tape disposal molding, machine mould cutter knife up 1.2mm wherein, and 20 ° of cutting-tool angles, interior straight tiltedly outer.
As preferably, described transparent substrate layer be specific refractory power close to the optical lens gelatin, have certain ageing-resistant performance and film forming properties optical grade film material preferably.
As preferably, described transparent substrate thickness is 200um～250um.
As preferably, the thickness of described OCA optics glue-line is 40 um～60 um.
The utility model foam when cross cutting is cut edge bright and clean, and die-cutting performance is good, the optical cement frame can not produce advantages such as the glue that overflows.Significantly promote capacitance touch screen optics and mechanical property, can well reduce the diffuse-reflectance of light, the water wave phenomenon of eliminating the generation of screen pressurized, enhancing capacitance plate water resistance, the electric capacity birthday scrolls inscribed with poems or messages wishing sb. a long life life that prolongs.Learning the thickness of transparent double sticky tape can adjust by the thickness of adjusting OCA optical cement or transparent substrate, thereby has solved the problem that thick type optical clear double sticky tape is made difficulty.And, with low cost, easy to implement, and implementation result is good.Have very strong practicality, market outlook are wide.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Fig. 1 is structural representation of the present utility model.As shown in Figure 1, a kind of optical clear adhesive tape for capacitance touch screen, mainly formed by transparent substrate 3, OCA optics glue-line 2, the heavy film 4 of PET, the light film 1 of PET etc., described transparent substrate layer 3 is that specific refractory power is close to the optical lens gelatin, have certain ageing-resistant performance and film forming properties optical grade film material preferably, its thickness is 200um～250um; These transparent substrate 3 two sides are respectively equipped with OCA optics glue-line 2, and the thickness of OCA optics glue-line 2 is 40 um～60 um, and this transparent substrate 3 is formed the transparent optical adhesive tape with OCA optics glue-line 2.The optical clear double sticky tape is designed to three-decker, transparent substrate 3 is adopted in the middle layer, OCA optical cement 2 is adopted on the two sides of transparent substrate 3, the thickness of whole like this optical clear double sticky tape can be adjusted by the thickness of adjusting OCA optical cement 2 or transparent substrate 3, thereby has solved the problem that thick type optical clear double sticky tape is made difficulty.The centre of OCA optical cement 2 has one deck base material 3 to intercept, thereby can effectively improve the good article rate in the cross cutting process, has also reduced transparent pair of monolithic optical virtually and the cost of adhesive tape.
The transparent optical adhesive tape simultaneously is provided with the heavy film 4 of PET, and another side is provided with the light film 1 of PET; The transparent optical adhesive tape is provided with on the light face 1 of PET by special moulding machine hemisection, machine mould cutter knife up 1.2mm wherein, and 20 ° of cutting-tool angles, interior straight tiltedly outer, make its transparent optical adhesive tape disposal molding.During use, directly optical cement is fitted between mobile phone capacitance plate or computer capacitance plate and the sheet glass by rigging machine, it is bonded together securely, thereby overcome the indeterminable technical problem of prior art.
