Title:
POLYETHYLENE COMPOSITION, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/093514
Kind Code:
A1
Abstract:
A polyethylene composition, a preparation method therefor, and a use thereof, relating to the field of polymer materials. The polyethylene composition comprises the following components in parts by weight: 60-85 parts of a polyethylene resin; 3-10 parts of EVA; 5-15 parts of a tackifying resin; 1.5-8 parts of white mineral oil; 5-15 parts of SBS; and 0-3 parts of a processing aid, wherein the VA content in the EVA is 10-30 wt%, and the number-average molecular weight of the tackifying resin is 1000-2000. EVA having certain VA content is used as a raw material for enhancing the polarity, oil-filled SBS and a tackifying resin of a certain molecular weight are used as components for improving fluidity and adhesion, and the proportions of the components are adjusted within certain ranges; thus, a composition material having good compatibility with EVOH, high adhesion and good fluidity can be obtained, and the co-extruded adhesive layer is uniform.
