Long-life ceramic coating, preparation method and rolling wheel

The invention discloses a long-service-life ceramic coating, a preparation method and a rolling wheel, the long-service-life ceramic coating sequentially comprises a first buffer connecting layer, a ceramic substrate layer, a second buffer connecting layer and a metal protective layer which are arranged in a layered mode, and the first buffer connecting layer is arranged on the surface of a metal lining; each of the first buffer connecting layer and the second buffer connecting layer comprises a cross-linking agent, an amino silane coupling agent and silicon nitride, and the cross-linking agent at least comprises epoxy resin. The metal lining and the ceramic substrate layer can form similar connection strength on the two sides of the amino silane coupling agent, stress can be evenly shared by the two sides of the amino silane coupling agent as much as possible, and the connection service life of the metal lining and the ceramic substrate layer is prolonged. 本发明公开了一种高寿命陶瓷涂层、制备方法及滚压轮，依次包括层状设置的第一缓冲连接层、陶瓷基底层、第二缓冲
