Abstract

The invention provides a thermosetting fluororesin powder coating formula which comprises the following raw materials by mass: 30-40 parts of cyclohexyl vinyl ether, 30-40 parts of isobutyl vinyl ether, 60-80 parts of 4-hydroxybutyl vinyl ether, 250-350 parts of teflon vinyl ether, 20-30 parts of a catalyst and 30-40 parts of a crosslinking agent. The coating prepared according to the formula is high in dispersibility, and good in surface gloss, and has the advantages of high temperature resistance, low temperature resistance, and chemical corrosion resistance and the like.

Description

technical field [0001] The invention relates to a thermosetting fluororesin powder coating formulation. Background technique [0002] With the development of society, the requirements for environmental protection are getting higher and higher. Due to its low pollution, high environmental protection, high efficiency, and high decorative properties, powder coatings account for an increasing proportion in the industrial coatings industry. As one of the representatives of high-grade coatings in powder coatings, the development of thermosetting fluororesin powder coatings has great market potential. At present, most of the research and development technologies of thermosetting fluororesin powder coatings are mastered in New Zealand, Japan and other countries. The high price greatly limits the promotion and application of products. Therefore, it is urgent to develop and apply domestic thermosetting fluororesin powder coatings. Contents of the invention [0003] The problem to ...
