Description

Technical Field

[0001] The present invention relates to the technical field of surface stretching of polyimide films, and specifically to a device for surface treatment of stretched polyimide films. Background Art

[0002] Polyimide film is a yellow transparent film with outstanding high temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation properties. It can be used in air at 250-280°C for a long time. Its relative density is between 1.39 and 1.45. The tensile strength is 200 MPa at 20°C and still greater than 100 MPa at 200°C. The operating temperature range is relatively wide, from more than one hundred degrees below zero to two or three hundred degrees; Polyimide films include two types: pyromellitic polyimide films and biphenyl polyimide films; the former is prepared from pyromellitic dianhydride and diaminodiphenyl ether; the latter is prepared from biphenyltetracarboxylic dianhydride and diphenyl ether diamine (type R) or m-phenylenediamine (type S).

[0003] In the manufacturing process of existing polyimide films, internal stresses may be introduced. These internal stresses may cause problems such as warping, shrinking or deformation of the film in subsequent applications. Through stretching treatment, these internal stresses can be released, making the film more stable. And the stretching treatment helps to make the surface of the polyimide film smoother, reducing or eliminating small irregularities and wrinkles on the surface. It also helps to improve certain physical properties of the polyimide film, such as tensile strength, heat resistance, chemical corrosion resistance, etc. At the same time, the stretched polyimide film can better maintain its original shape and performance in applications, improving the reliability and stability of product use.

[0004] However, the possible defects in the surface stretching of existing polyimide films include:

[0005] 1: There may be small irregularities, wrinkles or bubbles on the film surface, resulting in an uneven surface of the pre-heated film;

[0006] 2: During the pre-heating process, due to the stretching properties of the film, if continuous stretching cannot be carried out in time, the film may bulge or deform;

[0007] 3: During the manufacturing process, internal stresses may be introduced into the film. If the stretching treatment is not sufficient, the internal stresses may remain, resulting in problems such as warping, shrinking or deformation of the film during application.

[0008] Therefore, we propose a device for surface treatment of stretched polyimide films. Summary of the Invention
