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 instruments and meters, transportation facilities, and aluminum profiles. Powder coating can provide metals with excellent anti-corrosion However, due to the unsatisfactory anti-pollution performance of the existing coatings used in the above fields, various types of dust, dirt and even oil are often attached to the coatings; the anti-sticking ability is not ideal, and the existing powder coatings form Under the influence of natural conditions such as long-term outdoor exposure and rain, the coating is prone to blistering, cracking, peeling, etc. Therefore, the mechanical properties of the coating are not ideal

Abstract

The invention discloses a lanthanum oxide containing powder coating and a preparation method thereof. The powder coating comprises the following raw materials by weight: 40-50 of saturated polyester resin, 45-50 of polybutylene terephthalate, 65-70 of polytetrafluoroethylene, 40-50 of alumina, 23-28 of silica gel powder, 20-25 of talcum powder, 3.5-4.5 of lanthanum oxide, 9-11 of activated carbon powder, 2.5-3.5 of fatty alcohol-polyoxyethylene ether and 2.5-3.5 of a film forming agent. The powder coating provided in the invention adopts saturated polyester resin and polybutylene terephthalate as main raw materials, and lanthanum oxide, activated carbon powder and the film forming agent are added to enhance the mixing property among each raw material. At the same time, the surface leveling of the powder coating is improved. With high gloss retention, the powder coating has improved decorative property. And the prepared product has a high qualified rate.
