High-barrier graphene-modified polyethylene material and method for preparing the same

Abstract

This invention provides a high-barrier graphene-modified polyethylene material and its preparation method. The high-barrier graphene-modified polyethylene material is mainly prepared from the following raw materials in parts by weight: 95-99 parts polyethylene, 0.1-5 parts graphene oxide, 0.1-0.3 parts antioxidant, and 0-5 parts other additives; the polyethylene has a density of 0.910-0.970 g / cm³. 3 The high-barrier graphene-modified polyethylene material prepared by the method of the present invention requires a low amount of graphene addition; furthermore, the method of the present invention has excellent processing performance and is suitable for the production and processing of various products such as pipe materials, film materials, and injection molding materials.
