Abstract

The invention belongs to the technical field of preparation of a multifunctional polymer material, and specifically relates to a preparation method of a low-air-resistance antistatic antirust film. Anantirust outer film is made from ethyl cellulose; a sodium phytate solution is made into an antirust agent, which is treated to obtain an antirust inner film; and the outer film and inner film undergo hot pressing to obtain an antirust film. The antirust agent is a metal polydentate chelating agent. When phytic acid is complexed to metal, a layer of a compact single-molecule protection film is formed at the surface. Since a single molecule electron hole conductive layer is formed at the surface of treated metal, the conductive layer makes a passivated metal film layer conductive to lead the current out, and an antistatic effect is achieved. An alloy surface treated by benzotriazole and contained in the antirust outer film can isolate the metal surface from a corrosion inhibition medium, so that the film is excellent in corrosion inhibition effect, and is maintained with low air resistance, and outer air is prevented from permeating into the film and corroding the protected metal. Thefilm is of great significance.

Description

technical field [0001] The invention belongs to the technical field of preparation of multifunctional polymer materials, and in particular relates to a preparation method of a low gas impedance electrostatic antirust film. Background technique [0002] During the transportation and storage of metal and metal products, it is easy to be corroded by the atmosphere, which will affect the appearance, performance, or even be scrapped. Comes in rust-proof packaging. Antirust film is a new generation of innovative high-tech products based on the combination of polymer materials and VCI vapor phase antirust technology development. After the anti-rust metal article is packaged and sealed with an anti-rust film, the VCI contained in the film begins to sublimate and volatilize the anti-rust gas factor, which diffuses and penetrates to the surface of the anti-rust article and adsorbs it, forming a dense protective film layer with a thickness of one molecule , to isolate various factors...
