[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 an E-12 epoxy resin powder coating and a preparation method thereof. The composing raw materials are E-12 epoxy resin, hydroxyalkyl amide T105M, urotropine, acrylic acid ester levelling agent, petroleum sulfonate, benzoin, nano attapulgite, hydroxypropyl methyl cellulose, modified nano brick slag powder, and titanium dioxide. The E-12 epoxy resin powder coating has excellent luster, harness, solvent resistance and weatherability. Through modifying the nano brick slag powder, compatibility of the nano brick slag powder is largely improved, and the cost is reduced. Comprehensive performances such as low-temperature deforming resistance ability, fatigue resistance ability, water-damage resistance ability and aging resistance ability, of the E-12 epoxy resin powder coating are also improved; therefore the service life of the coating is prolonged.
