▎ 摘　　要

NOVELTY - Biodegradable material comprises 15-30 pts. wt. natural plant fiber, 20-30 pts. wt. high molecular polymer, 30-50 pts. wt. corn starch, 5-10 pts. wt. coconut shell powder, 0.1-0.3 pts. wt. cellulase, 0.5 to 3 pts. wt. silane coupling agent, 2-3 pts. wt. graphene, 0.2-0.5 pts. wt. egg shell powder, 0.2-0.5 pts. wt. silver nano ions, and 5-10 pts. wt. biodegradation agent. USE - Biodegradable material. ADVANTAGE - The biodegradable material is environmentally friendly, non-toxic, has high strength, good stability, biodegradability, market application value and performance indicators reaches national standards. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing biodegradable material using natural plant fibers, which involves: (A) weighing egg shell powder and silver nano ions and synthesizing egg shell/silver nano ions by one-step ball milling method, washing natural plant fibers, drying, and pulverizing to obtain 100-150 mesh plant short fibers; (B) adding the treated plant short fibers to purified water, and then adding cellulase, alkalizing in lye, and then washing to neutrality to obtain pretreated plant short fibers; (C) placing pre-treated plant short fibers in a high-speed mixer, adding egg shell /silver nano ions, coconut shell powder, and biodegradation agent, stirring and mixing; (D) adding the silane coupling agent to the mixed material for coupling treatment; and (E) adding corn starch, high polymer, and graphene to the material after coupling treatment, sending it to the mixing mixer for blending and kneading, after the kneading treatment is completed to obtain highly wear-resistant biodegradable material.
