Energy-saving and environment-friendly powder coating and preparation method thereof

Abstract

The invention discloses an energy-saving and an environment-friendly powder coating and a preparation method thereof. The energy-saving and an environment-friendly powder coating comprises the following composition raw materials: modified epoxy resin, high-density polyethylene resin, an organosilicone levelling agent, film-forming resin, polydimethylsiloxane, fatty amine, zinc powder, methacrylic resin, nanoscale titanium dioxide, 4,4'-diamido-diphenyl sulphone, resorcinol, bis-tetradecyl alcohol ester and chlorcosane. The powder coating disclosed by the invention is a green and environment-friendly coating which is non-toxic, is high-temperature-resistant, does not contain a solvent and is free from VOC (volatile organic compounds) discharge, and the powder coating disclosed by the invention is strong in surface levelling property and high in gloss retention, thus decoration property is improved; and the prepared finished product is high in pass percent, and capable of realizing industrialized mass production.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to an energy-saving and environment-friendly powder coating and a preparation method thereof. Background technique [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 also not ideal, and the coating formed by the existing powder coating is prone to blistering, cr...
