Processing method of antistatic powder coating

Abstract

The invention discloses a processing method of an antistatic powder coating and belongs to the technical field of chemical coatings. The processing method comprises the following steps: adding a sodium hydroxide aqueous solution into a silver nitrate solution with the volume of 0.005 mol/L to form a mixed solution; stirring the mixed solution, and instilling dilute ammonia water into the stirred mixed solution; carrying out precipitation-dissolution to obtain a Tollen reagent; preparing a mixture by mixing the following components in percentage by weight: 10 percent of modified resin, 2 percent of kaolin, 2 percent of a dispersing agent, 2 percent of white carbon black, 0.5 percent of a surfactant, 2 percent of a modifier and 0.5 percent of calcium carbonate; carrying out grinding, drying,crushing and the like on the mixture and finally obtaining the antistatic powder coating. The processing method of the antistatic powder coating, disclosed by the invention, adopts a clear preparation principle and scientific components; compared with traditional powder coating, the antistatic powder coating prepared by the processing method disclosed by the invention has the advantages that antibacterial and antistatic properties are realized, the safety use demands of the powder coating are met, the safety performance of the powder coating is improved, potential safety hazards are reduced as well as personal injury and property loss are reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, and relates to a processing method of powder coatings, in particular to a processing method of antistatic powder coatings. Background technique [0002] The common traditional paints in the market are made of natural resin or synthetic resin as the base material, and then add various pigments, various fillers, additives and solvents through mechanical processing. Some resins have poor wear resistance and some have friction in the use environment, which often causes the paint film to wear out and lose its function; on the other hand, because polymer materials are mostly insulating materials, static electricity is often generated in a dry environment. There will be greater harm, even danger; and due to the humid and hot environment, etc., the paint film will be overgrown with enzymes and bacteria.
