| description | This application relates to a back roller and a preparation method thereof, and a coating machine. The back roller includes a roller body and a wear-resistant layer. The roller body has an axis and a roll surface disposed around the axis. The wear-resistant layer covers the roll surface. Vickers hardness of the wear-resistant layer is denoted as H, and 800 HV ≤ H ≤ 1400 HV. The roll surface is covered by the wear-resistant layer, and the Vickers hardness H of the wear-resistant layer is controlled to be between 800 HV and 1400 HV, so that the roll surface is effectively protected, and wear resistance of the roll surface is improved. In this way, the wear-resistant layer is in direct contact with a material during operation, thereby effectively reducing an abrasion loss on the roll surface and extending the service life of the roll surface. In addition, the wear-resistant layer is disposed on the roll surface, thereby avoiding out-of-range run-out on the roll surface due to wearing of an outer surface of the back roller during long-term use, and helping ensure operation accuracy. |
