Problems solved by technology

[0002] In recent years, with the rapid development of the coatings industry, conductive coatings have received extensive attention in basic research and various basic industries, but at present, most conductive materials based on conductive coatings have dark black or dark green appearance characteristics. Such as polypyrrole, polyaniline and other polymers, or carbon-based, metal-based conductive coatings, etc., these dark conductive coatings lead to poor dyeability in the later stage, thus limiting product applications

Abstract

The invention discloses a preparation method of a coated conductive whisker/composite antistatic coating. The preparation method comprises the following steps: preparing a rutile type TiO2 crude product, calcining the rutile type TiO2 whisker crude product, pickling the rutile type TiO2 whisker crude product and then calcining the rutile type TiO2 whisker crude product, preparing a reaction solution, controlling the pH value for treatment, preparing a light-color coated conductive whisker, and preparing a light-color composite conductive coating. According to the preparation method of the coated conductive whisker/composite antistatic coating provided by the invention, microwaves are selected as a heat source in the preparation process, a light-color conductive material based on rutile TiO2 whiskers is prepared in a solid-phase environment, and the light-color antistatic coating is prepared by taking the light-color conductive material as a conductive base material. In addition to the advantage of high whiteness value, due to the physical structure characteristic of a rod shape, bridging and a conductive loop are easier to form, and the antistatic performance of the prepared finished product is ensured.
