Abstract

The invention discloses a method for preparing a degradable buffer material by using macro fungi mycelia. The method comprises the following steps: smashing agricultural and forestry wastes such as cottonseed hulls, bran and sawdust which serve as raw materials, adding a fixed amount of matrix nutrient into the raw materials to prepare a mycelium growing matrix, and putting the matrix into a sealable mold; after high-pressure wet heat sterilization is completed, inoculating a liquid strain of macro fungi into the mold; wrapping and bonding matrix micro particles to form a whole according to the feature that the mycelia are mutually twisted for growth in the matrix; after the mycelia grow to a certain extent, performing mold release growth to enhance the water resistence and the durability of the mycelia, and finally drying the mycelia to obtain the material. The material prepared by the method disclosed by the invention is extremely high in buffering property and mechanical property, can be completely and naturally degraded, and has a practical significance for comprehensive use of agricultural and forestal production wastes and protection of the environment.

Description

technical field [0001] The invention relates to a method for preparing a degradable buffer material by using macrofungus mycelium, and specifically belongs to the technical field of biomass materials. Background technique [0002] With the rapid rise of e-commerce and logistics industries, the cushioning packaging industry is developing rapidly, especially foam plastics (such as polyurethane PU, polystyrene EPS, polyvinyl chloride PVC, polypropylene) produced from non-renewable and precious petrochemical resources. PP, phenolic resin PF, etc.), film plastics, etc. are widely used. According to the statistics of the development of the international packaging industry, the foam (film) plastic packaging used in the food industry alone accounts for about 50% of the total packaging material consumption. Foam (film) plastic packaging becomes plastic waste because it is difficult to degrade naturally after being discarded. It accumulates and spreads in large quantities in the envi...
