Problems solved by technology

The coating has good abrasion resistance and impact resistance, but the production process is complicated and the cost is high
Chinese patent (CN-1060858A) discloses a preparation method of a conductive coating with carbon black or graphite as a conductive filler, but the dispersion stability of the coating is poor, and the color is dark and relatively single, which is not conducive to the color matching of the coating. For the requirement of light color The coating system is not suitable for
These three conductive coatings all use precious metals, which are costly and have poor conductivity

Abstract

The invention provides a conductive coating, comprising the following raw materials in parts by weight: 5-20 parts of film-forming materials, 20-75 parts of conductive powder and coupling agents in a ratio of 100:2-10 and 5-30 parts of thickening agents. The conductive powder is one or more of nickel powder, aluminum powder, zinc powder, titanium powder, manganese powder, chromium powder, silver-plated nickel powder, silver-plated aluminum powder, nickel-plated copper powder and silver-plated copper powder. The conductive coating can be used on the shells of computers, mobile phones, GPS, electromedical equipment, electronic instruments and electronic and electrotechnical communication products and has obvious electromagnetic shielding effect.

Description

Technical field: [0001] The invention relates to a novel conductive coating and a preparation method thereof, belonging to the technical field of chemical industry. Background technique: [0002] Conductive paint is a conductivity of 10 -10 s.cm -1 Above, the paint that has the ability to conduct electric current and dispel the accumulated electrostatic charge. The coating generally contains matrix resin, solvent and conductive substance, which can form a conductive coating on the substrate. On the one hand, it can prevent the interference of electromagnetic wave radiation in the environment on the signal of electronic products, so that the signal of electronic products is fidelity and stable; on the other hand, it can prevent the electromagnetic wave radiation pollution of electronic products on the environment, and keep the signal of electronic products confidential. As a fluid material, the coating has the advantages of simple preparation method, low cost, and can be c...
