Abstract

The invention discloses a degradable polyethylene plastic and a preparation method thereof. The degradable polyethylene plastic is prepared from the following raw materials in parts by weight: 65 to 80 parts of polyethylene, 10 to 20 parts of mikania micrantha extract, 8 to 15 parts of bentonite, 5 to 8 parts of ipomoea cairica, and 1 to 5 parts of zirconocene chloride. The degradable polyethyleneplastic has the advantages that the raw materials are easy to obtain and are environment-friendly, so that the mechanical property and degrading speed are obviously improved; the preparation technology is simple, the industrialized production is easy, and the degradable polyethylene plastic is suitable for being popularized.

Description

Technical field [0001] The invention relates to a composite material, in particular to a degradable polyethylene plastic and a preparation method thereof. Background technique [0002] Polyethylene is a thermoplastic resin made by polymerization of ethylene. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, and can withstand most acids and alkalis. It is widely used in the packaging industry. Due to the slow degradation of polyethylene products, it often takes tens or even hundreds of years to degrade naturally, and the abuse of polyethylene packaging products has caused serious pollution to the environment, which has become a problem that needs to be solved urgently. [0003] As people have a deeper and deeper understanding of environmental issues, degradable plastics are currently a hot research object. Degradable plastics are plastics that can be degraded in the sense of thermodynamics and kinetics over a per...
