Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a metallized film production method, which solves the problem that during the current metallized film production process, dust is easily attached to the surface of the film body in the previous processes, making the coating process difficult. It is easy to include impurities in it, and the coating thickness is not easy to control, resulting in poor coating quality

Abstract

The invention discloses a metallized film manufacturing method which comprises the following steps: pretreatment: putting a film into a drying oven, then introducing decarburization gas into the drying oven at the temperature of 80-95 DEG C, and after decarburization is completed, carrying out secondary corona discharge treatment on the working surface of the film; vacuum evaporation is conducted, specifically, the pretreated thin film is placed in a vacuum coating machine to form a metal coating on the surface of the thin film in a vacuum coating mode; and coating is conducted, specifically, the thin film obtained after evaporation is completed is coated through a coating device, the working face of the thin film is coated with a top coating with the temperature being 80-85 DEG C, and the back face of the thin film is coated with a bottom coating with the temperature being 70-75 DEG C. The invention relates to the technical field of metallized thin films. According to the manufacturing method of the metallized film, the two sides of the film can be cleaned at the same time, and the horizontal position of the film can be prevented from deviating through opposite blowing of the upper cleaning device and the lower cleaning device, so that the subsequent coating operation is prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of metallized thin films, in particular to a method for making metallized thin films. Background technique [0002] Whether it is new energy power generation, new energy vehicles or urban rail transit, power equipment is ultimately required to drive, convert or realize. In power equipment, capacitors are an important part of energy storage components, especially in new energy As an unconventional energy source, in the process of its comprehensive utilization, traditional power equipment, especially capacitors, have high requirements in terms of volume, voltage resistance, temperature resistance, current impact resistance, reliability, and service time. Metallized film capacitors best meet their requirements, and the most critical material in this regard is metallized film. At present, when the metallized film is coated during the production process, since the surface of the film body is easily attached to d...
