Title:
MODIFIED CROSS-LINKED POLYETHYLENE AND PREPARATION METHOD THEREFOR, AND RECYCLED PRODUCT AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/152182
Kind Code:
A1
Abstract:
The present invention provides a modified cross-linked polyethylene and a preparation method therefor, and a recycled product and a preparation method therefor. The preparation method for the modified cross-linked polyethylene comprises: milling waste cross-linked polyethylene by using a solid-phase force chemical reactor, and then using asphalt as a plasticizer for plasticization to obtain modified cross-linked polyethylene. The plasticization treatment enables the decross-linked waste cross-linked polyethylene/asphalt material obtained after milling to have excellent processing fluidity, and thus, the decross-linked waste cross-linked polyethylene/asphalt material is suitable for preparing high-performance recycled products in various thermoplastic processing processes. The waste cross-linked polyethylene ultrafine powder subjected to asphalt plasticization can be formed in a compressive force field having a high pressure, and can also be suitable for thermoplastic extrusion processing of a low shear force field. The prepared recycled product has good mechanical properties.
