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

Embodiment 1

[0018] Example 1: A powder coating with high-density polyethylene as the main ingredient, the parts by weight (kg) of the raw materials are: high-density polyethylene 49, polybenzimidazole 28, quartz sand 19, montmorillonite powder 26, activated carbon powder 5.0, dicobalt trioxide 2.5, hydrotalcite powder 6.0, diffusing agent NNO 7.0 and film forming agent 5.8.

[0019] The preparation method of the powder coating with high-density polyethylene as main material comprises the following steps:

[0020] (1) Carbon coated hydrotalcite powder:

[0021] a: Grind hydrotalcite powder to 120-130 mesh, then add it into deionized water according to the weight of the raw materials, the weight ratio of hydrotalcite powder and deionized water is 1:2.5, and mix evenly;

[0022] b: Add glucose accounting for 12% of the mass of hydrotalcite powder to the obtained mixed solution, stir, and mix evenly, then add molybdenum carbide accounting for 1.3% of the mass of glucose, stir and mix evenly;...

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.
