Problems solved by technology

[0005] The object of the present invention is to provide a kind of long-acting antistatic agent, preparation method and antistatic film, aiming at the influence of factors such as aging and bonding performance of conductive additives in existing antistatic agent products, aging impedance enhancement, Peeling off, etc. lead to a decline in the antistatic performance of the product. Therefore, by optimizing the combination of conductive additives and film-forming substances in the antistatic agent, a good coating combination is formed, and the form of associated microcapsules is formed in the dry state. While improving the film-forming property, it also effectively optimizes the anti-aging and anti-peeling properties of the product, and effectively improves the stability and service life of the product

Abstract

The invention discloses a long-acting antistatic agent, a preparation method and an antistatic film, and the antistatic agent is prepared from the following raw materials in parts by weight: 1-5 parts of imidazoline salt, 0.2-2 parts of quaternary ammonium salt, 0.1-1 part of amine salt, 0.5-1 part of single-walled carbon nanotube, 5-10 parts of resin, 2-5 parts of dispersing agent and 87-96 parts of deionized water. By optimizing the cooperation of the conductive auxiliary agent and the film-forming substance in the antistatic agent, the anti-aging and anti-stripping properties of the product are effectively optimized while the film-forming property is improved, the stability of the product is effectively improved, and the service life of the product is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of electronic antistatic coatings, in particular to a long-acting antistatic agent, a preparation method and an antistatic film. Background technique [0002] Films will accumulate static electricity during die-cutting or use. When a large amount of static electricity accumulates, it will cause damage to warehouses or equipment, and is prone to fire. When the electronic industry uses protective films and other films, when the static electricity accumulates a lot and the voltage is too large, it is easy to break down the electronic equipment, resulting in paralysis and damage to the electronic equipment. Static electricity will adsorb dust and impurities in the air, so in a clean environment, it is necessary to remove static electricity from the surface of the object. Spraying or directly coating an antistatic agent on the surface of the object can avoid the influence of static electricity and eliminate or re...
