Embodiment Construction
[0012] The technical solution of the present application will be further described below.
[0013] A high-temperature-resistant and anti-shedding powder coating, which is formed by mixing flame-retardant and high-temperature-resistant materials and high-temperature-resistant and anti-oxidation materials. The content is 80-90 parts by weight, the content of the high-temperature-resistant and anti-oxidation material is 10-20 parts by weight, and the weight percentage of the thermosetting flame-retardant and high-temperature-resistant modified resin in the flame-retardant and high-temperature resistant material is 75-85%. In this plan, the flame retardant and high temperature resistant material and the high temperature and oxidation resistant material are placed in an air stirring reactor for mixing. The high temperature resistant and anti-shedding powder coating has better performance, and the mixing time is set at about 40 minutes. Through continuous stirring, the temperature i...

Abstract
The invention relates to a high-temperature-resistant anti-falling powder coating. The powder coating is formed by mixing a flame-retardant high-temperature-resistant material and a high-temperature-resistant antioxidant material. The flame-retardant high-temperature-resistant material comprises thermosetting flame-retardant high-temperature-resistant modified resin. The content of the flame-retardant high-temperature-resistant material is 80-90 parts by weight, and the content of the high-temperature-resistant antioxidant material is 10-20 parts by weight. The thermosetting flame-retardant high-temperature-resistant modified resin accounts for 75-85% of the flame-retardant high-temperature-resistant material. The powder coating is formed by mixing the flame-retardant high-temperature-resistant material and the high-temperature-resistant antioxidant material, has high-temperature-resistant and corrosion-resistant effects, and has the following properties: the highest temperature resistance reaches 700 DEG C, after the powder coating is soaked in a diluted sulfuric acid solution for 240 hours at the temperature of 80 DEG C, the powder coating is free of the phenomena of pulverization, bubbling, cracking, falling and the like, and the powder coating is low in cost, high in cost performance, suitable for industrial production and very high in practicability.
