Problems solved by technology

In the prior art, the typical application of matte aluminum foil MYLAR conductive tape is LCD electromagnetic shielding and shading. However, the current domestic aluminum foil MYLAR has poor softness, easy edge warping, surface ink treatment is not resistant to solvents, fingerprints, and is not There are many problems such as scratch resistance, poor or uneven electrical conductivity of the product, and even electrical conductivity on the surface, which leads to safety hazards during use, which restricts the large-scale application of aluminum foil MYLAR

Embodiment 1

[0039] Stir and mix 100 parts of ink, 30 parts of toluene, 5 parts of curing agent and 10 parts of matting agent evenly to make an ink treatment layer, then fully filter the prepared ink treatment layer with a 400-mesh filter cloth, and seal it for later use ; Then clean the matte aluminum foil MYLAR substrate to remove surface oil and impurities, coat the polyester film surface with an ink treatment layer 3 times, and place the semi-finished product in an oven for aging; then apply the anti-scratch and anti-fingerprint solution 100 parts, 20 parts of ethyl acetate, and 5 parts of matting agent are stirred and mixed evenly to make a functional coating, and to be used, apply the functional coating twice on the mature ink treatment layer; then, on the other side (aluminum foil side) Coat the adhesive layer, and attach the release layer on the adhesive layer; store the prepared matte anti-fingerprint and anti-scratch aluminum foil MYLAR conductive tape for electromagnetic wave shi...

Embodiment 2

[0041] This embodiment is roughly the same as Example 1, the only difference being that the component contents of the ink treatment layer and the functional coating material are different, wherein the components of the ink treatment layer are: 120 parts of ink, 36 parts of toluene, 6 parts of curing agent and 12 parts of matting agent, the components of the functional coating are: 120 parts of anti-scratch and anti-fingerprint solution, 24 parts of ethyl acetate, and 6 parts of matting agent. The rest will not be repeated.

Embodiment 3

[0043] This embodiment is roughly the same as Example 1, the only difference being that the component contents of the ink treatment layer and the functional coating material are different, wherein the components of the ink treatment layer are: 150 parts of ink, 45 parts of toluene, 7.5 parts of curing agent and 15 parts of matting agent, the components of the functional coating are: 150 parts of anti-scratch and anti-fingerprint solution, 30 parts of ethyl acetate, and 7.5 parts of matting agent. The rest will not be repeated.

Description

technical field [0001] The invention relates to an anti-fingerprint, solvent-resistant and scratch-resistant aluminum foil MYLAR conductive adhesive tape for electromagnetic wave shielding and a preparation method, belonging to the technical field of electromagnetic wave shielding. Background technique [0002] With the rapid development of electronic technology, computers and radio communications are widely used and densely configured, which greatly facilitates and technologicalizes our lives. However, at the same time, the radiation of electromagnetic waves will have different effects on our organs, tissues and systems. The degree of harm, long-term exposure to electromagnetic radiation environment may have the risk of cancer. As people pay more and more attention to their own health, there are more and more in-depth researches on how to effectively control electromagnetic radiation. [0003] Aluminum foil MYLAR is a new type of material that is gradually replacing tradit...
