Title:
PREPARATION METHOD FOR EVA MATERIAL AND EVA MATERIAL
Document Type and Number:
WIPO Patent Application WO/2024/011919
Kind Code:
A1
Abstract:
The present invention provides a preparation method for an EVA material. The preparation method comprises the steps of preparation, crosslinking and molding. The present invention further provides an EVA material obtained by using the preparation method. In the present invention, a mechanical blending method is used, and an ester exchange reaction is used under the action of a catalyst so as to obtain an EVA material with dynamic cross-linking bonding. Due to dynamic cross-linking bonding, the cross-linked EVA can be recycled and processed by using a conventional plastic hot-processing method, and after multiple cycles of processing, good mechanical performance is still maintained; relatively good physical and mechanical properties are kept; and the utilization rate is relatively high.
