Degradable anti-electrostatic packaging material and preparation method thereof

Abstract

The invention provides a degradable anti-electrostatic packaging material and a preparation method thereof. The preparation method includes: (1) mixing multi-walled carbon nanotubes, yttrium iron garnet and concentrated nitric acid, putting mixture into an ultrasonic apparatus for ultrasonic dispersion, and stirring with a magnetic stirrer; (2) cleaning with distilled water prior to putting into a drying oven for drying to obtain mixed powder; (3) mixing mixed powder, expanded graphite, polylactic acid, polyhydroxyalkanoate, poly butylene succinate, chitin, cinnamon essential oil, ethylene distearamide, epoxidized soybean oil, triacetin and tributyl citrate with a high-speed mixer; (4) adding the mixture into an internal mixer for fusion and internal mixing. The degradable anti-electrostatic packaging material has good anti-electrostatic performance and good degradability, can effectively prevent electrostatic effect, and is excellent in mechanical property and anti-impact property.
