Description

technical field [0001] The invention belongs to the field of powder coatings, and in particular relates to a preparation method of fluorocarbon powder coatings. Background technique [0002] The paint industry has been identified as a polluting industry by the relevant administrative departments of the state. Under this situation, powder coatings, water-based coatings, UV-curable coatings, high solid content and solution-free coatings that meet the requirements of low-carbon environmental protection will become the priority development direction of the coatings industry. [0003] In recent years, in outdoor powder coatings, due to the erratic outdoor climate and high humidity, in hot and humid environments, powder coatings easily absorb moisture to form white spots on the surface, which affects the use and appearance of powder coatings. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a preparation method of fluorocarbon powder coating, ...
