Traditional pressure sensitive adhesive and adhesive tape do not have self-adsorption function

Traditional pressure-sensitive tape, protective film, and cold mounting film in the process of laminating, generally need manual detailed laminating, due to the protective film and cold mounting film itself self-adsorption performance is not good, need some ways to assist adsorption, such as Water spraying wetting, or scraper hanging, etc., need to repeat laminating to remove the bubbles generated in the laminating process, waste a lot of time and manpower, and cause a waste of resources.

The Chinese patent document CN114085411A (application No. : 202111524295.9) has disclosed a kind of imprint photoresist release film material with exhaust function, including a substrate layer, with an upper surface and a lower surface. It also includes a photoresist prepolymer coated on the upper surface or the lower surface of the substrate layer.

The photoresist prepolymer is solidified by light radiation to form an imprint lithography layer at the same time through mechanical contact on the surface of the embossed to form a plurality of exhaust grooves or exhaust grooves; The exhaust grooves or grooves divide the embossed lithography layer into convex blocks. The pressure-sensitive adhesive product forms an imprint lithographic adhesive layer on the substrate layer and forms an effective exhaust groove or exhaust groove by means of mechanical contact to solve the exhaust problem of viscous materials or pressure-sensitive adhesive products.

At present, the technical problem to be solved is to put forward a kind of emulsion type, forming a small closed air chamber in the adhesive layer, the pressure-sensitive adhesive with the self-adsorption function of automatic pressure exhaust air when sticking, and the tape using the pressure sensitive adhesive. People come up with a design that includes the following elements: Soft monomers 25 ~ 35, hard monomers 5 ~ 10, functional monomers 1 ~ 3, peroxide oxidant 0.01 ~ 0.1, reducing agent 0.1 ~ 0.9, emulsifier 0.5 ~ 1, foam stabilizer 0.1 ~ 1, pH regulator 0.01 ~ 0.2, pure water 50 ~ 60.
