Abstract

The invention provides an anti-static powder coating. The anti-static powder coating comprises carboxyl-terminated polyester resin A, carboxyl-terminated polyester resin B, triglycidyl isocyanurate, a dispersant, conductive carbon black, carbon nanotubes, a hardening filler, a leveling agent, a first auxiliary agent, a second auxiliary agent, a brightener, benzoin, polytetrafluoroethylene and a pigment. After the hardening filler is mixed with modified wax and a carboxylic acid derivative, the dispersion degree and compatibility of the hardening filler in a powder coating system can be improved. Polyacrylate is used as a surface additive, so that the leveling property and defoaming effect of the powder coating system are obviously improved, synergistic interaction is achieved, and the anti-static performance of the prepared powder coating is obviously improved. The carbon nanotubes and the carbon black exist in the powder coating system in a fine particle reinforced phase mode, and under the interaction of the components, the weather resistance of the coating is still excellent after the coating is used for a long time.

Description

technical field [0001] The invention relates to the field of preparation of powder coatings, in particular to an antistatic powder coating and a preparation method thereof. Background technique [0002] Static electricity is when two substances are in close contact and then separated, one substance transfers electrons to another substance and is positively charged, and the other substance gets electrons and is negatively charged. Although the static electricity is not large, because of its high voltage, it is easy to discharge and cause static sparks to cause explosions, and static electricity will also affect the normal operation of daily equipment. And powder coating can be sprayed in some daily equipment, forms the coating that has protection, decoration and special function on equipment surface, but the coating that the powder coating of the prior art forms can not play excellent antistatic effect, is often affected by gas Or the friction of dust in the air will generat...
