Abstract

The invention provides a powder coating for an induction cooker panel. The powder coating is prepared from, by weight, 60-70 parts of organosilicone modified polyester resin, 30-40 parts of epoxy resin, 1-1.5 parts of diethylenetriamine, 5-8 parts of ferric oxide, 1-2 parts of polyvinyl butyral, 8-10 parts of magnesium carbonate, 5-6 parts of mica powder, 1-2 parts of polyvinylpyrrolidone, 15-20 parts of light calcium carbonate, 1-2 parts of zircon powder, 0.2-0.5 part of benzoin, 8-10 parts of magnesium hydrate, 0.2-0.5 part of tri(n-dodecanol)ester, 8-10 parts of carbon black and 0.2-0.4 part of modified anion powder. The powder coating has high temperature resistance, good flame retardance, low curing temperature and short curing time, a film is good in leveling property, high in adhesive force, good in appearance and resistant to acid and base, indoor air can be purified, and the powder coating can be used for household appliance products such as induction cookers, microwave ovens and ovens.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a powder coating for an induction cooker panel and a preparation method thereof. Background technique [0002] With the advancement of modern science and technology and the development of modern industry, the problem of environmental pollution has become increasingly prominent, which poses a great threat to human beings themselves and the environment on which human beings depend. Traditional coatings will produce a large amount of toxic and harmful waste gas and waste water during the manufacturing process or during the construction process, which will pollute the environment, air and water resources, especially solvent-based coatings, which will release Volatile organic compounds (VOC) into the atmosphere, its amount has reached more than 50%, causing serious secondary pollution. This problem has attracted the attention of many industrial countries. [0003] As a kind of green and envi...
