[0003] At present, most of the high-temperature coatings used for grills or grills on the market are still mainly liquid, which is not environmentally friendly. When the food is heated, the liquid coating will volatilize harmful substances and damage the human body; only a small part Barbecue racks use high-temperature resistant powder coatings, and this high-temperature-resistant powder coating is still based on silicone resin, which has relatively high cost and obvious defects. Although silicone resin has excellent high-temperature resistance, its resistance to charcoal and open flame Poor, still flakes

Abstract
The invention discloses a charcoal fire high temperature-resistant powdery coating special for barbecues. The charcoal fire high temperature-resistant powdery coating comprises 15 to 25% of epoxy resin, 15 to 25% of a high temperature-resistant material, 1 to 3% of a matting agent, 1.0 to 2.0% of a leveling agent, 0.3 to 0.5% of a charging agent, 35 to 45% of extinctionbariumsulfate and 10 to 15% of high temperature-resistant black. After being burned by charcoal fire (with the external flame temperature of at least 600 DEG C) in the barbecues for two hours, the powdery coating does not foamand fall off, has good adhesion and excellent mechanical properties under low gloss conditions, realizes a low cost, and solves the problem that the common powdery coating resisting a high temperature of 600 DEG C on the market still uses Wacker silicone resin, a high temperature-resistant filler wollastonite and copper chrome black as main materials, consumes a high raw material cost and has obvious defects and the silicone resin has poor charcoal fire and open fire resistance and can produce peeling and fall off after high temperature barbecue.
Description
technical field [0001] The invention relates to the field of chemical powder coatings, in particular to a charcoal fire-resistant high-temperature powder coating specially used for barbecue grills and barbecue grills and other industries. Background technique [0002] Powder coating is a 100% solidpowder that does not contain organic solvents. It is different from oil-based paints and water-based paints. It does not use solvent or water as a dispersion medium when coating, but uses air as a dispersion medium to evenly coat the workpiece. The surface is a new type of environmentally friendly paint that forms a special-purpose coating film after heating. Powder coating has the characteristics of no VOC, environmental protection, energy saving, high construction efficiency and wide application range. [0003] At present, most of the high-temperature coatings used for grills or grills on the market are still mainly liquid, which is not environmentally friendly. When the food i...
