Abstract

The invention provides a powder coating for a washing machine shell. The powder coating is prepared from, by weight, 80-90 parts of o-cresol-formaldehyde epoxy resin, 30-32 parts of hydantoin epoxy resin, 2-3 parts of ethanediamine, 0.5-1.0 part of boron trifluoride ethylamine complex, 3-5 parts of rosin modified phenolic resin, 2-4 parts of glycerin, 2-4 parts of nano-silicon dioxide, 2-4 parts of dimethyl silicone oil, 6-8 parts of vermiculite power, 1-3 parts of leveling agent, 1-2 parts of triethanolamine, 2-3 parts of oleic acid, 0.5-1 part of white oil, 20-25 parts of titanium dioxide, 3-5 parts of light calcium carbonate, 0.2-1 part of molybdenum disulfide, 0.1-0.5 part of benzoin and 0.3-0.5 part of modified negative ion powder. The powder coating is good in corrosion resistance, water resistance and insulating property, low in curing temperature and short in curing time, the coating film is good in leveling property, high in adhesion, good in appearance, resistant to acid and alkali and capable of purifying air, and the coating can be used for household electrical appliances of washing machines and the like.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a powder coating for a washing machine casing 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 envir...
