Abstract

The invention provides a method for preparing a biomass cushion packaging material. The method comprises the following steps: grinding corn straws, and screening; adding a sodium hydroxide solution, and stirring; filtering and washing to obtain a product A; screening manioc waste, soaking in the sodium hydroxide solution, stirring, filtering, drying and grinding; adding dendrocalamus sinicus powder and benzene-alcohol solution, mixing and extracting; stirring with an alcohol aqueous solution; preparing an aqueous suspension liquid, grinding and homogenizing to obtain a suspension liquid B; mixing konjac glucomannan, gingko starch and deionized water, heating and stirring; adding epoxidized soybean oil and acetyl tributyl citrate, and keeping on stirring; adding the product A and the suspension liquid B, stirring, azodicarbonamide, silver-loaded chitosan microspheres, vinyl acetate-ethylene copolymer emulsion and surfactant, and keeping on stirring; and injecting into a die, performinghot-press molding, and insulating and drying for 30 seconds in the die. The packaging material has good mechanical performance, good buffer performance and good antibacterial effect.

Description

technical field [0001] The invention relates to a preparation method of a biomass 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 biomass cushioning packaging material. The prepared...
