Problems solved by technology

Metal-based antistatic coatings have the best electrical conductivity, but due to the high price of metals, their production costs are relatively high, which limits their application range
The price of carbon-based antistatic coatings is low, but there are many problems such as easy deposition and agglomeration, poor dispersion, difficult to clean, and poor oil resistance.
Metal oxide-based antistatic coatings are rarely used in practice due to their poor electrical conductivity.

Abstract

The invention discloses a calcium carbonate / nickel composite conductive material matrix antistatic coating and a preparation method thereof. The antistatic coating comprises the following main components in percentage by weight: 10-70 percent of composite conductive material, 0.5-3.0 percent of dispersant, 0.5-3.0 percent of wetting dispersant, 0.1-2.0 percent of deformer, 0.1-2.0 percent of leveling agent, 10.0-50.0 percent of resin and the balance of mixed thinner. In the invention, the antistatic coating is prepared by adding the calcium carbonate / nickel composite conductive material with favorable conductivity so that the antistatic effect of the antistatic coating is equivalent to that of a metal matrix antistatic coating and is stable and unchanged along with the changes of temperature, time, moisture, and the like. Compared with the metal matrix antistatic coating, the prepared antistatic coating greatly decreases the production cost, improves the economic benefits of enterprises, simultaneously solves the problems of excessive metal material consumption, and the like, accords with the sustainable development strategy and can be widely applied to the fields of electronic equipment, container pipelines, indoor decoration, furniture finishing, and the like.

Description

technical field [0001] The invention belongs to the field of inorganic chemistry, and in particular relates to a calcium carbonate / nickel composite conductive material-based antistatic coating and a preparation method thereof. Background technique [0002] Conductive coatings refer to functional coatings that are applied to non-conductive substrates to have a certain ability to conduct current and dissipate static charges. Antistatic coatings are currently the most widely used type of conductive coatings, and have attracted more and more attention from scientific researchers and coating manufacturers. According to different raw materials and preparation methods, antistatic coatings can be divided into structural (intrinsic) antistatic coatings and composite (additive) antistatic coatings. The former uses conductive polymers as film-forming substances, and its antistatic effect mainly comes from the wet conductive film formed on the surface of the polymer after absorbing wat...
