Abstract

The invention discloses a method for preparing an anti-radiation anti-static thin film, and belongs to the technical field of thin film preparation. According to the method, polar powder is adopted as a raw material, lignocellulose is prepared, mixed liquid prepared from N-methylmorpholine oxide and propylgallate is concentrated to dissolve the lignocellulose, film coating liquid is prepared and smeared to the surface of glass, then soaking and drying are carried out, and an obtained cellulose film is soaked with mixed liquid prepared from butyltin trichloride, titanium dioxide and ethanediol; after dopamine hydrochloride is added, the pH is adjusted, dopamine hydrochloride polymerization is carried out, titanium dioxide and stannic oxide are attached, deposition is carried out on the surface of the cellulose film, then the thin film is washed and dried, and the anti-radiation anti-static thin film can be obtained. The prepared anti-radiation anti-static thin film has excellent anti-radiation and anti-static performance, an antistatic agent and the thin film are good in compatibility, coating is even, and wide application prospects are achieved.

Description

technical field [0001] The invention discloses a preparation method of an anti-radiation and anti-static film, which belongs to the technical field of film preparation. Background technique [0002] With the rapid development of the electronics industry, the integration of electronic circuit boards is getting higher and higher. The high density of electronic components on the motherboard, the compact wiring, and even the widespread use of surface mount components can easily lead to electrostatic damage to circuit boards. . When an American agency tested the integrated circuits in a large-scale communication system equipment, it was found that one-third of the faulty integrated circuits were broken down by electrostatic discharge. [0003] In addition, when the film material is rubbed, it is easy to generate static electricity, and the liquid crystal display is also prone to static electricity when it is working. Static electricity is extremely harmful to equipment, workshop...
