Description
Technical Field
The utility model belongs to the technical field of the touch-sensitive screen, specifically speaking, the utility model relates to a collapsible ultra-thin glass apron.
Background
Ultra-Thin Glass (UTG) is Glass having a thickness of 0.1mm or less. Due to its ultra-thin characteristics, it has excellent bendability and high hardness scratch resistance, and is a material that plays an important role in the field of foldable flexible cover plates following CPI film materials.
The conventional UTG product has good bending performance when the thickness is less than 0.1mm, and shows a tendency that the bending radius is smaller when the thickness is UTG mm. However, the thinner UTG, the lower the impact resistance, the greater the risk of splintering, and the failure to meet the end-use conditions. Therefore, it is important to perform a strengthening treatment on the surface of the ultra-thin glass.
Currently, UTG foldable lid products are available on the market, usually with UTG reinforcement by means of a fit. UTG is adhered to a foldable protective film with a hardened surface by using a foldable OCA (optical Clear adhesive), and the foldable protective film with the hardened surface is used as an outer surface, so that the foldable protective film can resist external impact and meet the use requirements of end customers. However, the foldable ultrathin glass cover plate in the form still has the problem of crease, and the long-term use of the product is influenced.
Although the impact resistance of UTG can be improved by adopting the attaching mode, the existing product usually needs to be attached twice, namely, the protective film is attached to the OCA first, and then the protective film is attached to UTG, so that the final product can be obtained. The multiple lamination inevitably causes the reduction of production yield, the requirement on production equipment is higher, the production process is prolonged, and the production cost is inevitably increased.
Meanwhile, the organic high molecular polymer is coated on the surface of UTG, and the solidified film is also the key direction for development of cover plate factories, so that the problem of crease is expected to be solved, and the performances of impact resistance, bending resistance and the like of the foldable ultrathin glass cover plate are optimized. However, the strength of the polymer film processed by the process is difficult to achieve, and the UTG protection effect is greatly reduced. In addition, the process needs to process various polymer materials, the process is complicated, the appearance and other problems are more, and the yield is extremely low.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving one of the technical problem that exists among the prior art at least. Therefore, the utility model provides a foldable ultra-thin glass cover plate, aiming at enhancing the shock resistance of the ultra-thin glass cover plate.
In order to realize the purpose, the utility model discloses the technical scheme who takes does: collapsible ultra-thin glass apron, including UTG and hot pressing type protection film, hot pressing type protection film including the protection rete and with the protection rete with the hot melt adhesive layer that UTG bonded, the thickness on protection rete is between 10 ~ 100um, and the thickness on hot melt adhesive layer is between 5 ~ 50 um.
The protective film layer is made of CPI, PET, TPU or PA.
The material of hot melt adhesive layer is acrylic glue, silica gel or epoxy glue.
The utility model discloses a collapsible ultra-thin glass apron through hot pressing type protection film, can strengthen the shock resistance of ultra-thin glass apron, is applicable to the collapsible electronic product in terminal, can reduce laminating technology moreover by a wide margin, reduces equipment, human input, promotes the production yield, reduction in production cost.

Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.
As shown in FIG. 1, the utility model provides a collapsible ultra-thin glass apron, including UTG1 (ultra-thin flexible glass) and hot pressing type protection film, hot pressing type protection film includes protection rete 2 and the hot melt adhesive layer 3 that bonds with protection rete 2 and UTG1, and the thickness of protection rete 2 is between 10 ~ 100um, and the thickness of hot melt adhesive layer 3 is between 5 ~ 50 um. The hot-pressing type protective film is bonded on UTG1 through hot pressing, so that the hot-pressing type protective film which can be bonded by hot pressing and UTG1 through hot pressing is arranged, the hot-pressing type protective film is bonded with UTG1 through hot pressing, the protective effect is achieved, the impact resistance of UTG1 is obviously improved, the impact resistance of the ultrathin glass cover plate is enhanced, and the protective film is suitable for terminal foldable electronic products.
Preferably, UTG1 has a thickness of 0.1mm or less, and the glass material and size are not limited, and the bending diameter is 0.5mm to 5.0 mm.
Preferably, the material of the protective film layer 2 includes, but is not limited to, foldable optical films such as CPI, PET, TPU, and PA.
Preferably, the material of the hot melt adhesive layer 3 includes, but is not limited to, hot melt and cooling solidification materials such as acrylic adhesive, silica gel, polyacrylic acid, epoxy resin adhesive, and the like.
The invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-described manner. Various insubstantial improvements are made by adopting the method conception and the technical proposal of the utility model; or without improvement, the above conception and technical solution of the present invention can be directly applied to other occasions, all within the protection scope of the present invention.
