Organic conductive coating and preparation method thereof

Abstract

The invention provides an organic conductive coating and a preparation method thereof, wherein the organic conductive coating comprises the following components in parts by weight: 8-15 parts of graphite, 1-6 parts of titanium dioxide, 0.05-0.15 part of antimony trioxide, 0.3-1.2 parts of magnesium oxide, 0.5-1.8 parts of lead oxide, 1-5 parts of titanium sesquioxide, 10-30 parts of alkyd resin, 0.2-0.8 part of silicone oil, 0.05-0.12 part of xylene, 0.1-0.8 part of epoxy resin and 0.3-0.7 part of barium carbonate. The preparation method comprises the following steps: firstly uniformly mixing the graphite, the titanium dioxide, the antimony trioxide, the magnesium oxide, the lead oxide, the titanium sesquioxide and the barium carbonate, then adding the alkyd resin, the epoxy resin and the silicone oil, uniformly stirring, further adding the xylene and uniformly mixing for preparation. The organic conductive coating provided by the invention has high adhesion force of above 98%, which is better than similar products; and furthermore, the electric conductivity is good, and the electric resistance is less than 60 ohm.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an organic conductive coating and a preparation method thereof. Background technique [0002] Conductive paint, as a liquid paint, can be easily sprayed or brushed on the surface of various shapes of materials to form an electromagnetic shielding conductive layer, so that the material can achieve the purpose of shielding electromagnetic waves. Conductive coating has the characteristics of low cost, simple process, convenient construction, wide application range and good effect of shielding electromagnetic waves, etc., and has been widely used. Conductive coatings are a special case of antistatic coatings, which usually contain a large amount of metal powders such as copper powder or carbon black, nickel powder, aluminum powder, molybdenum powder, and silver powder. At present, most conductive coatings used on plastic surfaces are concentrated in solvent-based co...

AI Technical Summary

Problems solved by technology

At present, most of the conductive coatings used on plastic surfaces are concentrated in solvent-based conductive coatings, and solvent-based conductive coatings will volatilize and eat a lot of harmful substances during use, causing harmful effects on the environment and people's health

However, the water-based paint has the problem of weak adhesion, which will cause the fragments of the paint film to fall into the circuit board in the casing and cause a short circuit.
