Abstract

The invention discloses a coating device, and particularly relates to a polyimide coating device which comprises a first roller and a second roller, the side face of the first roller is provided with a first scraper blade used for scraping off materials adhered to the first roller, the first scraper blade is provided with a second scraper blade used for scraping off materials adhered to the first scraper blade, and the second scraper blade is provided with a third scraper blade used for scraping off materials adhered to the third scraper blade. When the coating device is used, a film subjected to a casting process passes through the space between the first roller and the second roller, the first roller is used for uniformly extruding the film, and then the first scraper is used for scraping materials adhered to the first roller, so that the coating is more uniform, the use effect is good, and the efficiency is high. And the first scraping plate and the second scraping plate of the device are matched for use, so that scraping is more thorough.

Description

technical field [0001] The invention relates to the technical field of polyimide production, in particular to a polyimide coating device and a coating method thereof. Background technique [0002] Polyimide film is a new type of high temperature resistant organic polymer film, which is formed by polycondensation and salivation of pyromellitic acid and diaminodiphenyl ether in a strong solvent dimethylacetamide, and then It is formed by imidization. It is currently the best film insulating material in the world. It has excellent mechanical properties, electrical properties, chemical stability, and high radiation resistance, high temperature resistance and low temperature resistance. Now it has Widely used in various fields such as aviation, navigation, spacecraft, rocket missiles, atomic energy, and electronic and electrical industries. In the existing production method, the special equipment for polyimide production is used to coat the polyimide solution on the steel strip ...
