Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-resistant and flame-retardant powder coating. Background technique [0002] Powder coating is a new type of coating that does not contain solvents and is applied in powder form to form a coating film. Compared with traditional solvent-based coatings, powder coatings emit almost zero organic solvent volatiles (VOC) during curing, avoiding environmental pollution; at the same time, powder coatings have high utilization rate, good coating performance and easy implementation Advantages such as automated coating have achieved rapid development in recent years. [0003] Although there are various types of powder coatings at present, with the development of society, people put forward higher requirements for the performance of coatings. The performance of existing powder coatings can no longer meet the requirements of society, for example, poor heat resistance , poor flame ret...
