Treatment method of metal base material and material for preparing vehicle

The embodiment of the invention provides a treatment method of a metal base material and a material for preparing a vehicle, and relates to the field of vehicle preparation. The treatment method of the metal base material comprises the following steps that the metal base material is soaked in a zircon salt solution to form a zircon film, and the zircon salt solution is acidic; the zirconium salt solution also contains an additive, and the additive comprises one or two of sodium nitrate and sodium nitrite; the metal base material contains manganese, and the mass fraction of the manganese is not less than 0.5%. According to the material obtained by using the treatment method disclosed by the embodiment of the invention, the adhesive force between the metal base material and the zirconium film can be obviously improved. 本申请实施例提供一种金属基材的处理方法及用于制备车辆的材料，涉及车辆制备领域。金属基材的处理方法包括以下步骤：将金属基材浸泡于锆盐溶液中以形成锆化膜，锆盐溶液呈酸性；且锆盐溶液中还含有添加剂，添加剂包括硝酸钠、亚硝酸钠中的一种或两种；金属基材中含有锰，且锰的质量份数不小于0.5％。使用本申请实施例的处理方法得到的材料，金属基材和锆化膜之间的附着力能得到明显的提升。
