Embodiment 1

[0034] First prepare the double-sided adhesive film of the present invention: purchase film materials that meet the corresponding properties, and sequentially include a release film one (11), a first adhesive layer (131), a UV light isolation film ( 132), the second adhesive layer (133) and release film two (12) are set to obtain the double-sided adhesive film, and the thickness of the first adhesive layer (131) and the second adhesive layer (133) is 0.05 mm. The structural diagram of the double-sided adhesive film of the present invention is as follows figure 2 shown.

[0035] Prepare a glass substrate with a size of 550mm*650mm (the thickness of the substrate is 0.7mm), cut a wide double-sided adhesive film with a size of 540mm*640mm, and cut a film and a protective film with a size of 530mm*630mm on a film roll. The film material is COP. Those skilled in the art know that COP, PET, and TAC are all common materials for film, and the touch screen made of PET film is prone...

Abstract

The invention firstly provides a double-sided adhesive film. The double-sided adhesive film comprises a release film I, a first adhesive layer, a UV light isolation film, a second adhesive layer and arelease film II in the thickness direction sequentially, wherein the first adhesive layer, the UV light isolation film and the second adhesive layer jointly form a double-sided adhesive layer of thedouble-sided adhesive film, and the double-sided adhesive layer can withstand high temperature, strong acid and strong alkali environments in the process of developing and etching an ITO layer on thefilm; viscosity of the first adhesive layer and the second adhesive layer does not decrease significantly under the conditions of high temperature, strong acid and strong alkali, and the adhesive in the second adhesive layer is UV subtractive adhesive whose viscosity can be significantly decreased or lost after irradiation by UV light. The invention further provides a supporting method for forminga touch control structure on the film. According to the double-sided adhesive film and the Film supporting method, an expensive substrate can be fully reused, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of photoelectric product preparation, in particular to a double-sided adhesive film and a supporting method for forming a touch structure on a film film. Background technique [0002] Commercially available film rolls are generally wound from a film film 01 covered with a protective film 02 , and the touch screen obtained by forming a touch structure on the film film has the advantages of being light, thin and flexible. However, when the touch structure is formed on the film and the yellow light process is implemented, the film will curl. Therefore, in the prior art, the protective film 02 pasted with the film 01 is pasted and fixed on the substrate 03, such as image 3 As shown, the substrate generally uses a glass substrate. The structure of the double-sided adhesive film used for pasting and fixing between the protective film and the substrate in the prior art is as follows: figure 1 As shown, a release film is p...
