Abstract

The invention discloses a plastic packaging material and a preparation method thereof, and the plastic packaging material is prepared from the following raw materials in parts by weight: polypropylene, an ethylene-octylene copolymer, polyethylene, polyisobutene, 2, 4, 6-trimethyl-1, 3-pentanediol monoisobutyrate, a flame retardant, an antioxidant and a lubricant. The composite material is prepared from 1, 2-bis (4-hydroxyphenyl) propane, montmorillonite, hydrogen-containing silicone oil, synthetic plant ester, a silane coupling agent, nano silicon dioxide, graphene, modified calcium sulfate whiskers and an antioxidant. In the preparation process of the plastic packaging material, the montmorillonite is subjected to ball milling treatment by using the hydrogen-containing silicone oil, so that the binding capacity of the montmorillonite to an organic phase in the raw materials can be improved, the surface area of the montmorillonite can be increased by reducing the particle size of the montmorillonite, and the hydrophobicity is improved; in the preparation process, a three-layer co-extrusion process is selected, the packaging material with a three-layer structure is prepared, the preparation process is simple, the preparation efficiency is high, the product flexibility is good, the tensile property is excellent, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of packaging material processing, in particular to a plastic packaging material and a preparation method thereof. Background technique [0002] Plastic packaging material is an indispensable item in people's daily life. It can be used to carry other items. It has the characteristics of low price, light weight and large capacity. With the advancement of commercialization, the steady increase in the number of commodities has led to further prosperity of plastic packaging materials. Plastic packaging materials are mostly polyethylene plastic films or polypropylene plastic films, which belong to synthetic polymer materials. They are generally made of synthetic resins with fillers, plasticizers, stabilizers, lubricants, reinforcing agents, etc., and have stable chemical properties. performance. Polypropylene is a crystalline polymer with the advantages of good thermal stability, corrosion resistance and high me...
