A kind of antistatic composite film

Abstract

The invention discloses an anti-static composite film. The anti-static composite film comprises a polyurethane base layer, and an anti-static layer arranged on the polyurethane base layer; the anti-static layer is a linear low density polyethylene polymer layer containing modified conductive polyaniline fiber; and the content of the modified conductive polyaniline fiber in the linear low density polyethylene polymer layer is controlled to be 5 to 20wt%. According to a preparation method, low density polyethylene particles low in benzene series compound content and alkane compound content are taken as raw materials, and modified conductive polyaniline fiber capable of improving electrical conductivity and mechanical strength is added. The anti-static composite film prepared via the preparation method is capable of ensuring basic antistatic performance, and reducing adding amount of metal at the same time, and reducing the difficulty of environment pollution treatment and recycling, and is beneficial for environment protection. Adding of the modified conductive polyaniline fiber is capable of improving tear resistance of the anti-static composite film greatly, and increasing the mechanical strength of the anti-static composite film, and is beneficial for protection of electron components in packaging film from mechanical damage.

Description

technical field [0001] The invention relates to an antistatic composite film, in particular to an antistatic composite film suitable for wrapping electronic components. Background technique [0002] Static electricity is a common but complex physical phenomenon, it is invisible and ubiquitous. With the rapid development of science and technology, the improvement of high production efficiency and automation, and the widespread use of electronic equipment, the static and electromagnetic environment is getting worse and worse, which makes products sensitive to static electricity and electromagnetic radiation such as integrated circuits, electromagnetic Control systems, chemical agents, etc. pose a threat. Due to external electromagnetic radiation, failures and malfunctions of integrated circuits and electromagnetic control systems, and accidents of chemical product combustion and explosion occur from time to time. During the production, storage, transportation and use of chem...
