Problems solved by technology

The use of such fibrous conductive polyaniline to prepare antistatic materials is conducive to reducing the content of conductive components in the film-forming resin and the amount of solvent used, reducing pollution and controlling production costs; on the other hand, after polyaniline is synthesized from aniline monomer Combined with film-forming resin to prepare antistatic ink, the process is many and cumbersome, the pollution is serious, and the cost is high

Abstract

The invention discloses an in-situ preparation method of polyaniline antistatic printing ink The invention is characterized in that in the method, methyl methacrylate, butyl acrylate, hydroxyl ethyl acrylate, styrene and benzoyl peroxide are used as the materials under a dimethylbenzene solvent system for synthesizing polyacrylate glue; then in the double-phase solvent of dimethylbenzene and water with the existence of the polyacrylate glue, the water and deposits at a lower layer are removed through centrifugalizing, thus being capable of obtaining the greenblack polyaniline antistatic printing ink.. The method has the advantages of simple technique, easy operation and less pollution. The product prepared by the invention can be broadly applied to the products and fields of durable and stable antistatic performances and high dryness.

Description

technical field [0001] The invention belongs to a preparation method of ink, and relates to an in-situ preparation method of polyaniline antistatic ink. The product prepared by the invention is used in the field of antistatic. Background technique [0002] Conductive polyaniline is a new intrinsic conductive polymer material. The antistatic material prepared by conductive polyaniline has long-lasting and stable conductivity and is not easily affected by humidity and temperature. It is especially suitable for high dryness and high antistatic requirements. products and fields. In the prior art, conductive polyaniline antistatic materials are generally first synthesized polyaniline under acidic aqueous solution conditions, then dissolve and / or disperse conductive polyaniline doped with protonic acid in a suitable solvent, and then compound with film-forming resin , be prepared into a conductive ink that can be coated on the surface of the product that needs to be protected (t...
