The invention discloses a powder coating and a preparation method and a use method thereof. The powder coating comprises the components by weight: 60 parts-80 parts of electron beam curing type polyester resin, 20 parts-40 parts of a pigment and filler and 1 part-5 parts of an auxiliary agent. By the adoption of the powder coating and the preparation method and the use method thereof, energy consumption needed during curing can be reduced, the process is simple, VOC emission is avoided, the hardness of a coating film is high, the powder coating is green and environmentally friendly, can be used for a colored coating layer with the thickness of hundreds of microns, a coating film and a substrate can be chemically combined, and the adhesive force is improved. 本发明公开了一种粉末涂料及其制备和使用方法，该粉末涂料包括电子束固化型聚酯树脂、颜填料和助剂，其中电子束固化型聚酯树脂、颜填料和助剂的重量比例是：电子束固化型聚酯树脂为60份到80份，颜填料为20份到40份，助剂为1份到5份。采用了本发明的技术方案，能够降低固化时所需的能耗，流程简单且无任何VOC排放，涂膜硬度高，对环境绿色友好，可用于厚达数百微米的有色涂层，能够使涂膜与底材产生化学结合提高附着力。
