▎ 摘　　要

NOVELTY - Preparing three-dimensional continuous network structure natural fiber composite material comprises granulating composite natural fibers, plastics and processing aids to obtain natural fiber composite particles, mixing natural fiber composite particles with inorganic particles for adsorbing inorganic particles on surface of natural fiber composite particles to obtain natural fiber composite particles covered by inorganic particles, melting natural fiber composite particles covered by inorganic particles to obtain natural fiber composite material containing three-dimensional network structure. USE - The method is useful for preparing three-dimensional continuous network structure natural fiber composite material in building part, outdoor guardrail and paving, automobile interior trim, indoor furniture and decoration field. ADVANTAGE - The method: provides three-dimensional continuous network with inorganic particles as main body in natural fiber composite material system, intersperse inorganic particles in matrix of composite material in three-dimensional alternating vein form for distributes small amount of inorganic nanoparticles in composite material with higher density to exert higher efficacy; and enhances mechanical and dimensional stability of natural fiber composites while endowing them with functions i.e. flame retardancy, electrical conductivity, and electromagnetic shielding. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for three-dimensional network structure natural fiber composite material.
