本发明涉及不锈钢技术领域，具体是一种高平整汽车装饰用不锈钢带及其制备工艺，采用激光熔覆高熵合金层与离子氮碳共渗来提高不锈钢的硬度、耐磨性和耐蚀性；在预处理不锈钢带表面涂覆由自修复乳液、复合二氧化硅共混制备的保护涂料；合成侧链含有机硅预聚体，以二羟甲基丙酸为亲水扩链剂，以2,2'-二氨基二苯二硫醚继续扩链，以甲基丙烯酸羟乙酯为封端剂，在双键封端聚氨酯上接枝1-硫代甘油；通过氨基-环氧反应，将具有不同尺度的粒子通过化学键合组装起来，得到草莓状二氧化硅，利用草莓状二氧化硅表面的氨基，通过酰胺化反应进一步引入苯硼酸基、氟基团，构建微纳米尺度的多维疏水二氧化硅。 The invention relates to the technical field of stainless steel, in particular to a high-flatness stainless steel band for automobile decoration and a preparation process of the high-flatness stainless steel band for automobile decoration. Coating the surface of the pretreated stainless steel band with a protective coating prepared by blending a self-repairing emulsion and composite silicon dioxide; the preparation method comprises the following steps: synthesizing a prepolymer containing organic silicon on a side chain, continuing chain extension by taking dimethylolpropionic acid as a hydrophilic chain extender and 2, 2 '-diaminodiphenyl disulfide, and grafting 1-thioglycerol on double-bond terminated polyurethane by taking hydroxye
