Abstract

The invention relates to a special high-conductivity material for a conductive powder coating. The special high-conductivity material is prepared from the following raw materials in parts by weight: 10-50 parts of a conductive material, 0.3-5 parts of a cosolvent, 0.5-5 parts of a coupling agent and 2-10 parts of a wetting agent. By the adoption of a constant-temperature high-speed mixing technology, a preparation material is applied to the conductive powder coating, and polar groups such as hydroxide radical and anhydride are introduced, so that the conductive material is liable to be in contact with resin to form a space conductive network, and the conductivity is improved; moreover, the high-conductivity material can be reacted with the hydroxide radical on the surface of inorganic filler, so that reactive silanol is generated, and the interface property, the compatibility, the dispersion property and the flowability of the synthesized resin and the inorganic filler are effectively improved. The phenomenon of layering of the conductive material and a resin base material in a production process is avoided; furthermore, the prepared conductive powder coating is stable in conductivity; when the coating layer achieves the same conductivity, the technology compared with a common production technology has the advantages that the use amount of the conductive material is reduced by 10-40 percent, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of powder coatings, and relates to conductive powder coatings, in particular to a special high-conductivity material for conductive powder coatings and a preparation method. Background technique [0002] Conductive powder coatings refer to functional powder coatings that have a certain conduction current and dissipate charges after being coated on the substrate to form a film. They are mainly used to eliminate static electricity, electromagnetic shielding, electric heating and anti-corrosion. At present, the commonly used conductive coatings are mostly doped conductive powder coatings, that is, the polymer itself has no conductivity, and the insulating polymer is the main film-forming substance, which is formed by mixing conductive materials. Its conductivity depends on the incorporation. realized by conductive materials. Conductive materials include metal powders (gold, silver, copper, nickel, zinc, alumin...
