Problems solved by technology

Carbon black not only pollutes a lot and is troublesome to operate, but also because of its high addition amount, it will greatly reduce the impact strength, adhesion and wear resistance of the powder coating itself
Not only that, powder coatings using carbon black as conductive materials cannot be toned (can only be made into black), which greatly reduces the decorativeness of the coatings; and anti-static powder coatings using metal materials as conductive materials, although the color is richer , but its relative density is relatively high and the price is high, which greatly increases the production cost of coatings

Abstract

The invention discloses a powdery coating with electrostatic repellent effects. The powdery coating comprises, by mass, 60-100 parts of epoxy resin, 100-140 parts of polyester resin, 30-100 parts of afiller, 0.5-5 parts of a wrinkling agent, 0.5-3 parts of an anti-foaming agent, 0.2-2 parts of an antistatic agent, 1.0-10 parts of a pigment and 0.5-3.0 parts of a conductive material. The epoxy resin/polyester mixed resin system is used as a film forming material, an efficient conductive material is used, a conductive material use ratio is low, the conductivity is strong and a superior cost performance is obtained. The invention also discloses a preparation method of the powdery coating with electrostatic repellent effects.

Description

technical field [0001] The invention belongs to the technical field of powder coatings, and in particular relates to a powder coating with an electrostatic rejection effect and a preparation method thereof. Background technique [0002] Traditional anti-static powder non-coating conductive materials are mainly carbon black, metal materials and so on. Carbon black not only pollutes a lot and is troublesome to operate, but also because of its high addition amount, it will greatly reduce the impact strength, adhesion and wear resistance of the powder coating itself. Not only that, powder coatings using carbon black as conductive materials cannot be toned (can only be made into black), which greatly reduces the decorativeness of the coatings; and anti-static powder coatings using metal materials as conductive materials, although the color is richer , but its relative density is high and the price is high, which greatly increases the production cost of coatings.
