| description | The invention relates to an extension roller for preparing a polaroid PVA film and a manufacturing method thereof.The extension roller comprises a roller shaft and a rubber layer covering the outer layer of the roller shaft and composed of composite rubber, the rubber layer is composed of a solid rubber bottom layer and a foaming rubber surface layer, the solid rubber bottom layer covers the roller shaft, and the foaming rubber surface layer covers the roller shaft. And the foaming rubber surface layer is coated outside the solid rubber bottom layer. The extension roller is of a structure formed by combining the solid rubber bottom layer and the foamed rubber surface layer, a controllable special unsmooth surface is formed by controlling the foam structure and density of the foamed rubber surface layer, long-term stable friction force between the extension roller and a PVA film is provided, the friction force between the extension roller and the PVA film is controlled to be uniform, consistent and constant, a |
