Abstract

The invention provides an antibacterial environment-friendly cushion packaging material preparation method. The method includes steps: grinding cotton stalk chips, and screening; adding sodium hydroxide solution, and stirring; filtering and washing to obtain a product A; screening furfural residues, immersing into sodium hydroxide solution, stirring, filtering, drying and grinding; adding sunflower seed shell powder and benzene-ethanol solution, and performing mixed extraction; adding ethanol water solution, and stirring; preparing into water suspension, grinding and homogenizing to obtain turbid liquid B; mixing kandelia leaf extract, mung bean starch and deionized water, heating and stirring; adding sucrose octaacetate and ethylene glycol, and continuing stirring; adding the product A and the turbid liquid B, stirring, adding azodicarbonamide, canarium pimela extract, vinyl acetate-ethylene copolymer emulsion and a surfactant, and continuing stirring; injecting into a mould, performing hot press molding, and performing heat preservation and drying in the mould for 30s to obtain an antibacterial environment-friendly cushion packaging material. The packaging material has great mechanical properties, cushioning performances and great antibacterial effects.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial and environment-friendly cushioning packaging material. Background technique [0002] Since the 20th century, expanded polystyrene cushioning packaging materials have been widely used as cushioning packaging for electronic products, but expanded polystyrene has stable chemical properties and will not degrade naturally within 200 years under natural conditions after being discarded, causing serious " "White pollution", if the expanded polystyrene is recycled for degradation, it will cost a lot of money. Therefore, it will have very important practical significance for sustainable development to develop a natural degradable environmentally friendly green packaging material to replace the widely used expanded polystyrene foam material. Contents of the invention [0003] Technical problem to be solved: The purpose of this invention is to provide a preparation method of an antibacterial an...
