Problems solved by technology

[0002] With the continuous and stable growth of my country's economy and the continuous improvement of people's living standards, the powder coating business of metal components is also increasing, especially in industries such as household appliances, instruments and meters, transportation facilities, aluminum profiles, various vehicles, and daily hardware. , powder coating can provide metal with excellent anti-corrosion protection and decorative properties, but due to the unsatisfactory anti-pollution performance of existing coatings used in the above-mentioned fields, various types of dust, dirt and even oil are often attached to the coating; anti-sticking ability It is not ideal, and the coating formed by the existing powder coating is prone to blistering, cracking, peeling and other phenomena under the influence of natural conditions such as outdoor long-term exposure to the sun and rain. Therefore, the mechanical properties of the coating are not ideal

Abstract

The invention discloses a powder coating containing nanometer siliceous shale powder and a preparation method thereof. Raw materials for the powder coating comprise a polyamide resin, aluminum nitride powder, nanometer siliceous shale powder, glycerin, phthalic anhydride, aluminum silver powder, polyethylene wax powder, phenethyl naphthol polyoxyethylene ether, chlorinated paraffin, polyacrylate and a film-forming resin. The powder coating provided in the invention is a green environment-friendly coating which is nontoxic, high-temperature-resistant and free of a solvent and discharge of VOC; the polyamide resin is used as a main raw material for the coating and the film forming resin and the nanometer siliceous shale powder are added at the same time, so film forming ability of the powder coating is enhanced, surface leveling of the powder coating is improved, high gloss retention is realized, and decorative performance the powder coating is improved; a prepared finished product has a high qualified rate, and industrial large production can be realized.
