The invention belongs to the technical field of wire enamel, and particularly relates to a preparation method of high-adhesion and high-weather-resistance wire enamel, a polyimide resin solution and organic carbon chain structure modified filler are used as raw materials and are mixed and reacted to obtain a material, and a formula and a specific preparation method of the wire enamel are provided. The defect of solubility of polyimide is overcome, a polyimide resin solution is used as a raw material, the contact reaction between polyimide and the filler is effectively improved, and meanwhile, the filler and the polyimide material are fully wrapped and mixed by utilizing an organic carbon chain structure of the modified filler, so that the polyimide material is prepared. And the water resistance, the weather resistance and the insulativity of the enameled wire are greatly improved. 本发明属于漆包线漆技术领域，具体涉及一种高附着、高耐候漆包线漆的制备方法，以聚酰亚胺树脂溶液和有机碳链结构改性的填料为原材料，经混合反应得到材料，并提供了漆包线漆的配方和具体制备方法。本发明解决了聚酰亚胺自身溶解度的缺陷，以聚酰亚胺树脂溶液为原材料，有效的提升
