Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a manufacturing process of an antistatic PE protective film, which solves the problem that the excessive electrostatic voltage caused by the lack of antistatic property of the existing PE protective film will cause certain disadvantages to the surface of the PE protective film. At the same time, excessive static electricity can easily cause dust adsorption, easily pollute the PE protective film, and the PE protective film still has the problem of insufficient toughness.

Abstract

The invention provides a manufacturing process of an antistatic PE protective film, and relates to the technical field of protective films. The antistatic PE protective film is prepared from the following raw materials: 50 to 70 parts of polyethylene, 10 to 15 parts of waterborne polyurethane emulsion, 5 to 8 parts of gelatin, 4 to 7 parts of hydroxyl silicone oil emulsion, 1 to 5 parts of polyphenyl ether, 1 to 3 parts of cobalt boroacylate and 4 to 5 parts of decabromodiphenyl ether. The raw materials of the anti-static PE protective film can be fully mixed and melted through two times of mixing and banburying, it is guaranteed that the ultraviolet light absorber, the plasticizer, the flexibilizer, the antioxidant and the anti-static agent are fully mixed in the preparation process of the PE protective film, it is guaranteed that the functions of the components are effectively exerted, and the PE protective film can have the anti-static performance by adding the anti-static agent; the static electricity generated in the attaching or tearing process of the PE protective film is reduced, so that the surface of the PE protective film is effectively protected, dust adsorption of the PE protective film is reduced, and cleanliness and attractiveness of the PE protective film are guaranteed.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a manufacturing process of an antistatic PE protective film. Background technique [0002] PE protective film is the simplest polymer organic compound and the most widely used polymer material in the world today. PE protective film is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to different densities. [0003] However, due to the lack of antistatic properties of the existing PE protective film, a certain amount of static electricity will be generated during the lamination or tear-off process. If the electrostatic voltage generated is too large, it will have a certain adverse effect on the surface of the PE protective film. It is easy to cause the adsorption of dust, and it is easy to pollute the PE protective film. At the same time, the current PE protective film still has the problem of insu...
