Abstract

The invention discloses a polypropylene packaging material containing modified graphene. The polypropylene packaging material is prepared from the following raw materials in parts by weight: 70-85 parts of homo-polypropylene, 2-9 parts of propylene-ethylene copolymer, 5-11 parts of ethylene-1-hexene copolymer, 1-5 parts of calcium phosphate, 2-9 parts of aluminum hydroxide, 2-11 parts of organic silicon microspheres, 2-8 parts of modified halloysite, 5-15 parts of modified graphene oxide, 3-8 parts of nano titanium dioxide, 1-3 parts of zinc pyrithione, 1-5 parts of meso-porous silicon, 4-12 parts of bamboo fiber, 0.5-2 parts of epoxidized soybean oil, 0.3-2 parts of dibenzoyl hydrazine, 2-8 parts of compound plant extract, 3-11 parts of ammonium polyphosphate, 0.1-0.32 part of antioxidantand 0.1-0.35 part of calcium stearate. The polypropylene packaging material containing modified graphene disclosed by the invention has the advantages of high impact toughness, good anti-stain and bactericidal performance and excellent flame retardance.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a polypropylene packaging material containing modified graphene oxide. Background technique [0002] Polypropylene is rich in raw materials, has the advantages of high tensile strength, high yield strength, high hardness, high heat distortion temperature, and low price. It has been widely used in daily necessities, auto parts, packaging materials and other fields. However, polypropylene has high brittleness, low impact strength, and poor antibacterial and flame retardancy, which limit its application in the field of packaging materials. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a polypropylene packaging material containing modified graphene oxide, which has high impact toughness, good anti-fouling and sterilization properties, and excellent flame-retardant properties.
