Problems solved by technology

[0003] In addition, in the prior art, the central shaft of the winding is placed on the upper part of the winding device. After the winding is completed, the outer peripheral surface of the central shaft of the winding has been wrapped with a protective film, which will make the weight of the entire roll of protective film larger. The operator manually removes the entire roll of protective film, which will increase the labor intensity of the operator and is prone to accidents

Abstract

The invention discloses a wear-resistant high-temperature-resistant protective film with good holding power. The protective film comprises a surface layer, a middle layer and a bottom bonding layer which are connected from top to bottom, wherein each layer is prepared from components with special proportions, so that the protective film has the advantages of wear resistance on the surface, high temperature resistance in the interior, good holding power at the bottom and the like. In addition, the invention further discloses a production method of the protective film. The surface layer, the middle layer and the bottom bonding layer are synchronously produced through a co-extrusion process. In addition, the invention further discloses a winding device of the protective film, reliable winding of the protective film, edge trimming of the protective film, convenient adjustment and convenient width cutting are achieved through the winding device, and compared with the prior art, the winding device has the advantages of being reliable in winding, accurate in positioning, safe in work and the like; the working efficiency in the protective film winding process can be improved, the winding accuracy is guaranteed, and the labor intensity of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a protective film with good wear resistance, high temperature resistance and stickiness, a production method and a winding device. Background technique [0002] Protective film is a protective product that is often used in people's life or production process, such as the surface protective film of solar panels, the surface protective film for the production of display diffuser panels and the protective film for the production of display panels, etc. The protective film is used in industrial semi-finished or finished products During the production process, it can better protect the surface and avoid surface defects caused by oil pollution, metal debris damage to the surface, etc., and after the semi-finished product and other components are assembled into a finished product, the protective film can be removed To make it have a more beautiful appearance, the protective fil...
