Abstract

The invention discloses a superhydrophobic polyester resin powder coating, the raw materials of which include by weight: 45-50 parts of polyester resin, 22-26 parts of phenolic resin, 17-20 parts of hydroxyl acrylic resin, 13-20 parts of fluorine-containing hydrophobic material 16 parts, 8-12 parts of asphalt, 6-9 parts of magnesium carbonate, 6-8 parts of aluminum hydroxide powder, 1-3 parts of barium sulfate, 2-3 parts of zinc powder, 3-5 parts of curing agent, 2 parts of leveling agent -5 parts, 1-2 parts of matting agent, 1-3 parts of antioxidant, 1-2 parts of pigment dispersant. The superhydrophobic polyester resin powder coating proposed by the invention has excellent hydrophobic performance and is a powder coating with good antirust performance.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a superhydrophobic polyester resin powder coating. Background technique [0002] Powder coating does not contain solvents and does not release VOC. It is a pollution-free, recyclable and environmentally friendly coating. Its excellent brushing performance and film-forming performance promote its wide application. The powder coating with polyester resin as the main component has the characteristics of good process performance, high adhesion, high hardness after curing, good wear resistance and good flexibility. It is often used in metal antirust coatings, outdoor metal component coatings and other fields. However, with the variability of the atmospheric environment and the increase of pollutants, more stringent requirements are put forward for metal antirust coatings. How to further improve the hydrophobicity of polyester resin powder coatings and enhance their antirust ca...
