Abstract

The invention provides a heat-resistant and flame-resistant powder coating for a gas-cooker body surface layer. The heat-resistant and flame-resistant powder coating is prepared from, by weight, 8-10 parts of organic silicon resin, 10-20 parts of thermosetting fluorocarbon resin, 20-30 parts of hydroxyl polyester resin, 2-4 parts of isocyanate curing agent, 1-2 parts of 3-glycidoxypropyltrimethoxysilane, 5-8 parts of ferric oxide, 4-6 parts of ethylene-propylene-diene monomer, 5-10 parts of silica micropowder, 2-4 parts of zinc oxide, 4-6 parts of zirconium oxide, 15-20 parts of kaolin fine powder, 1-2 parts of bi-( 3,5-tertiary butyl-4-hydroxy phenyl ) sulfide, 5-8 parts of magnesium hydroxide, 8-10 parts of aluminum hydroxide, 0.5-1.0 part of 2-ethylhexyl methacrylate, 1-2 parts of polyvinylpyrrolidone, 0.2-0.4 part of acrylic ester flatting agent, 6-8 parts of carbon black and 3-4 parts of modified assistant. The heat-resistant and flame-resistant powder coating is good in heat resistance and flame resistance, low in curing temperature, short in curing time, good in coating flatting performance, high in adhesive force, good in coating appearance and resistant to acid and alkali, and can be applied to the gas-cooker body surface layer.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a heat-resistant and flame-retardant powder coating for the surface layer of a gas stove body 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 c...
