Technical Field

[0001] The utility model relates to the technical field of double-sided adhesive for touch screen cover plates, in particular to a novel rubber double-sided adhesive structure. Background Art

[0002] A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts, and a cover is one of the important components of a touch screen. In the prior art, in order to ensure the stable use of the touch screen cover, a double-sided foam adhesive is required to assemble the touch screen onto the casing. At the same time, the foam layer has a buffering effect, reducing the risk of the touch screen cover colliding with the casing and breaking the screen.

[0003] However, it is well known in the technical field that foam does not have the characteristics of resistance to strong acids and alkalis, water vapor, aging resistance, ozone resistance, etc. when working in harsh environments, so that the touch screen cannot be used in a variety of working environments, especially in relatively harsh working environments. Therefore, in view of the problems existing in the prior art such as those mentioned above, we have designed a new rubber double-sided adhesive structure for touch screen cover.

[0010] As a further solution of the utility model: the top and the bottom of the weather-resistant layer are designed to be frosted surfaces.

[0011] As a further solution of the utility model: sealing sheets are arranged on the left and right sides and the front and back sides of the double-sided adhesive body, and the four sealing sheets are integrally formed with reinforcing sheet 1 and reinforcing sheet 2 on one side close to the double-sided adhesive body.

[0016] 1. In the present application, a weather-resistant layer is designed, that is, the foam of the foam double-sided adhesive buffer layer on the touch screen cover is replaced with a weather-resistant layer made of EPDM rubber. Since EPDM rubber is resistant to strong acids and alkalis, 150° water vapor, aging, and ozone, the touch screen can be used in relatively harsh environments and can be suitable for a variety of operating environments. EPDM rubber has good softness and can provide a good buffering effect for the touch screen. At the same time, the double-sided adhesive is selected from bonding double-sided adhesive tape 1 and bonding double-sided adhesive tape 2. The bonding double-sided adhesive tape 1 and bonding double-sided adhesive tape 2 are solid double-sided adhesive tapes that are resistant to high temperature and waterproof, which can increase the firmness of the adhesive and enable the touch screen to operate in harsh industrial environments without falling off.

[0017] 2. In the present application, by designing the sealing sheet, reinforcing sheet 1 and reinforcing sheet 2 and other structures, the four sides of the double-sided adhesive body can be shielded and protected. On the one hand, it can prevent external moisture and dust from invading the interlayer, and on the other hand, it can enhance the bonding tightness of the multi-layer structure on the side of the double-sided adhesive body, reduce the occurrence of stratification, and thus effectively improve the service life of the double-sided adhesive body.

[0030] It should be noted that the thickness of the adhesive double-sided tape 1 2 and the adhesive double-sided tape 2 4 is smaller than the weather-resistant layer 3 , and the weather-resistant layer 3 can be used to provide a good buffering effect for the adhesive double-sided tape 1 2 and the adhesive double-sided tape 2 4 , thereby improving the stability during use.

[0031] See also Figure 2 In this embodiment, the lengths and widths of the adhesive double-sided tape 1 2 , the weather-resistant layer 3 , the adhesive double-sided tape 2 4 , and the release film 5 are all the same.

[0032] It should be noted that the areas of the adhesive double-sided tape 1 2 , the weather-resistant layer 3 , the adhesive double-sided tape 2 4 and the release film 5 are the same, which can facilitate the fitting during use and ensure the stability during use.

[0036] It should be noted that the upper and lower surfaces of the weather-resistant layer 3 are both frosted structures, which can increase the contact area, improve the adhesion stability between the bonding double-sided adhesive tape 2 4 and the bonding double-sided adhesive tape 1 2, and reduce the possibility of delamination.

The four sealing sheets 6 are integrally formed with a reinforcing sheet 1 601 and a reinforcing sheet 2 602 on one side close to the double-sided adhesive body. The four sealing sheets 6 are provided with adhesive on one side close to the double-sided adhesive body, and the four sealing sheets 6 are respectively bonded to the four side sides of the double-sided adhesive body and cover the side sides of the bonding double-sided adhesive 1 2, the weather-resistant layer 3 and the bonding double-sided adhesive 2 4; adhesive is also provided on the top and bottom of the reinforcing sheet 1 601 and the reinforcing sheet 2 602, the reinforcing sheet 1 601 is bonded between the weather-resistant layer 3 and the bonding double-sided adhesive 2 4, and the reinforcing sheet 2 602 is bonded between the bonding double-sided adhesive 1 2 and the weather-resistant layer 3; the sealing sheet 6, the reinforcing sheet 1 601 and the reinforcing sheet 2 602 are all made of PVC plastic, and the adhesives on the sealing sheet 6, the reinforcing sheet 1 601 and the reinforcing sheet 2 602 are all acrylic adhesives.

[0038] It should be noted that, through the designed sealing sheet 6, a shielding structure can be formed on the sides of the bonding double-sided tape 2, the weather-resistant layer 3 and the bonding double-sided tape 4, so as to prevent external dust or moisture from invading between the layers, thereby avoiding the occurrence of stratification between the layers, and making the bonding between the layers more precise. At the same time, the adhesives on the sealing sheet 6, the reinforcing sheet 1 601 and the reinforcing sheet 2 602 are all acrylic adhesives, which can ensure the tightness of the sealing sheet 6, the reinforcing sheet 1 601 and the reinforcing sheet 2 602 and the corresponding structure when connected, and can reduce the occurrence of detachment.

[0040] Then, the reinforcing sheet 1 601 is bonded to the top surface of the weather-resistant layer 3, and the bottom surface of the bonding double-sided adhesive tape 2 4 is bonded to the top surface of the weather-resistant layer 3, so that the bottom surface of the bonding double-sided adhesive tape 2 4 is pressed against the top surface of the reinforcing sheet 1 601, thereby completing the bonding closure of the reinforcing sheet 1 601 between the weather-resistant layer 3 and the bonding double-sided adhesive tape 2 4;

[0041] Then press the sealing sheet 6 to make the sealing sheet 6 more tightly bonded to the side surfaces of the bonding double-sided adhesive tape 1 2, the weather-resistant layer 3, and the bonding double-sided adhesive tape 2 4;

[0042] Finally, the release film 5 can be bonded to the top surface of the double-sided adhesive tape 2 4 , and when it is needed later, only the release film 5 needs to be torn off.
