Embodiment 1

[0035] 100 parts (parts by weight) of homopolypropylene resin, 0.2 part of graphene oxide / nanometer silver, 0.1 part of tetrakis [β-(3,5-di-tert-butyl 4-hydroxyphenyl) propionate] pentaerythritol ester (anti- Oxygen agent 1010) was added into the high mixer together, and mixed at a speed of 300 rpm for 5 minutes; the mixed blend was extruded and granulated by a twin-screw extruder to obtain an antibacterial polyolefin.

Embodiment 2

[0037] 100 parts (parts by weight) of copolymerized polypropylene resin, 0.3 part of graphene oxide / nanometer silver, and 1 part of tris-(2,4-di-tert-butylphenyl) phosphite (antioxidant 168) were added to the high-mixing In the machine, mix at a speed of 300 rpm for 6 minutes; extrude and granulate the mixed blend through a twin-screw extruder to obtain an antibacterial polyolefin.

Embodiment 3

[0039] 100 parts (parts by weight) of copolymerized polypropylene resin, 0.4 part of graphene oxide / nanometer silver, 0.5 part of tetrakis [β-(3,5-di-tert-butyl 4-hydroxyphenyl) propionate] pentaerythritol ester (antioxidant Add agent 1010) into the high mixer together, and mix at a speed of 300 rpm for 8 minutes; extrude the mixed blend through a twin-screw extruder to obtain antibacterial polyolefin.

Abstract

The invention discloses anti-bacterial polyolefin and a preparation method thereof. The anti-bacterial polyolefin is prepared by mixing and extrusion on 100 parts of polypropylene resin, 0.2-1 part ofa composite antiseptic, and 0.1-1 part of an anti-oxidant; and the composite antiseptic is graphene oxide having a surface loaded with nano silver particles. The anti-bacterial polyolefin has obviousantibacterial property, and has the characteristics of wide antibiosis scope, safety and reliability, no odor, and low harm and pollution degree on a human body and environment.

Description

technical field [0001] The invention relates to the technical field of modified materials, in particular to an antibacterial polyolefin and a preparation method thereof. Background technique [0002] Polypropylene (referred to as PP) has the advantages of excellent mechanical properties, low density, good heat resistance, excellent bending fatigue resistance, chemical stability and electrical properties, and is currently one of the most widely used general-purpose plastics. One of the uses of polypropylene is that it can be injection molded into a lunch box, which is not only resistant to steam, but also can be used in microwaves. It is one of the main tableware used in daily life in the family. But there is the shortcoming that the lunch box on the market is not antibacterial, affects people's health. This is because microorganisms are easy to infect humans, animals and plants as pathogenic bacteria in the form of bacteria, molds, etc., causing diseases and endangering hum...
