The invention provides a preparation method of EVA material, which comprises the following steps of preparation, cross-linking and molding. The present invention also provides an EVA material obtained by the above preparation method. The invention adopts a mechanical blending method and utilizes a transesterification reaction under the action of a catalyst to obtain an EVA material with dynamic cross-linking bonding, and the dynamic cross-linking bonding enables the cross-linked EVA to be processed by a conventional plastic thermal processing method. It is recycled and processed, and it still maintains good mechanical properties after multiple cycle processing, and maintains good physical and mechanical properties. The utilization rate is relatively high. |
