Powder coating with high density polyethylene as main ingredient and preparation method thereof

Abstract

The invention discloses a powder coating with high density polyethylene as a main ingredient and a preparation method thereof. The powder coating comprises the following raw materials by weight part: 48-55 of high density polyethylene, 27-33 of polybenzimidazole, 18-22 of quartz sand, 25-30 of montmorillonite powder, 4.5-5.5 of activated carbon powder, 2.0-3.0 of cobaltic oxide, 5.0-7.0 of hydrotalcite powder, 6.0-8.0 of a dispersing agent NNO and 5.0-6.5 of a film-forming agent. In the invention, high density polyethylene is adopted as the main raw material, and the hydrotalcite powder and the film forming agent are added so as to enhance the mixing performance among each raw material and improve the surface leveling of the powder coating simultaneously. With high gloss retention, the powder coating has improved decorative performance. And the prepared product has a high qualified rate.

Description

technical field [0001] The invention relates to a powder coating, in particular to a powder coating with high-density polyethylene as the main material 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 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, and peeling....
