Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a combined material technical field, specificly relate to a developments ebonite.
[ background of the invention ]
The double-sided adhesive paper is commonly known as double-sided adhesive tape, also called adhesive paper and adhesive tape, and is mainly made into a roll product by coating adhesive on two sides of a certain base material, and is used for bonding objects.
However, the existing double-sided adhesive paper generally adopts a structure of a first adhesive layer, a PET layer, a second adhesive layer and a release paper layer, but the structure has relatively poor shock resistance, high flexibility and reversible deformability, and is not suitable for installation of a touch screen, a lens or a screen, a display and a flexible OLED display, installation of an ultrathin glass frame or installation of a curved surface design, which require high shock resistance.
In view of the above, it is desirable to provide a dynamic black glue to overcome the deficiencies of the prior art.
[ Utility model ] content
The utility model aims at providing a developments ebonite is through replacing traditional PET layer for acrylic acid foam layer for developments ebonite has shock resistance, high pliability, reversible deformability and the waterproof characteristics of IP8 level, can bear long-term folding and keep the characteristics of high cohesiveness, and the double-sided bonding, the application is extensive, and market prospect is good.
In order to achieve the above object, the utility model provides a dynamic black adhesive, which comprises a first modified adhesive layer, an acrylic acid foam layer, a second modified adhesive layer and a transparent release film layer;
The first modified adhesive layer is arranged on the acrylic foam layer, the acrylic foam layer is arranged on the second modified adhesive layer, and the second modified adhesive layer is arranged on the transparent release film layer; the total thickness of the dynamic black glue is 280-300 mu m.
In a preferred embodiment, the thickness of the first modified adhesive layer is 70-80 μm, the thickness of the acrylic foam layer is 60-70 μm, the thickness of the second modified adhesive layer is 70-80 μm, and the thickness of the transparent release film layer is 70-80 μm.
In a preferred embodiment, the thickness of the first modified adhesive layer is 70 μm, the thickness of the acrylic foam layer is 60 μm, the thickness of the second modified adhesive layer is 70 μm, and the thickness of the transparent release film layer is 80 μm.
Compared with the prior art, the utility model provides a pair of developments ebonite's beneficial effect lies in: through replacing traditional PET layer for acrylic acid foam layer for dynamic black glue has shock resistance, high flexibility, reversible deformation nature and IP8 level waterproof characteristics, can bear long-term folding and keep the characteristics of high cohesiveness, and two-sided bonding, the application is extensive, and market prospect is good.

[ detailed description ] embodiments
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1, the present invention provides a dynamic black glue 100.
Referring to fig. 2, in an embodiment of the present invention, the dynamic black glue 100 is in a tape shape and includes a first modified adhesive layer 10, an acrylic foam layer 20, a second modified adhesive layer 30, and a transparent release film layer 40.
Specifically, the first modified adhesive layer 10 is disposed on the acrylic foam layer 20, the acrylic foam layer 20 is disposed on the second modified adhesive layer 30, and the second modified adhesive layer 30 is disposed on the transparent release film layer 40; the total thickness of the dynamic black glue 100 is 280-300 mu m.
In a preferred embodiment, the thickness of the first modified adhesive layer 10 is 70 to 80 μm, the thickness of the acrylic foam layer 20 is 60 to 70 μm, the thickness of the second modified adhesive layer 30 is 70 to 80 μm, and the thickness of the transparent release film layer 40 is 70 to 80 μm.
In a preferred embodiment, the thickness of the first modified adhesive layer 10 is 70 μm, the thickness of the acrylic foam layer 20 is 60 μm, the thickness of the second modified adhesive layer 30 is 70 μm, and the thickness of the transparent release film layer 40 is 80 μm.
It will be appreciated that the acrylic foam is prepared from acrylic acid, a propylene amine and a propylene base material, crosslinked and cured by expanding foaming radiation with an organic blowing agent. The dynamic black adhesive 100 replaces the traditional PET layer with the acrylic foam layer 20, and due to the characteristics of the acrylic foam layer 20, the dynamic black adhesive 100 has the characteristics of shock resistance, high flexibility, reversible deformability and IP 8-grade water resistance, can bear the characteristic of long-term folding and keep high cohesiveness, and can be widely applied to installation of touch screens, lenses or screens requiring high shock resistance, installation of displays and flexible OLED displays, installation of ultrathin glass frames or curved surface design and installation of waterproof design. Meanwhile, the first modified adhesive layer 10 has the characteristic of weak initial adhesion, is not easy to adhere to dust, reduces the generation of bubbles during adhesion, and generates high adhesion after heating and pressure maintaining.
the technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
