Belonging to the field of recycled environmental-friendly materials, the invention specifically discloses a preparation method of high-performance sound insulation materials based on waste biomass and organic modifiers. Waste biomass such as plant fibers, wood and crop straws is sorted, cleaned and crushed in advance. Organic modifiers containing specific functional groups are synthesized separately. Biomass particles, organic modifiers, inorganic sound-absorbing fillers, plasticizers and lubricants are blended in proportion and uniformly mixed by a high-speed mixer. The mixture is extruded, cooled and pelletized through a twin-screw extruder to obtain finished products. The synergistic effect between modifiers and biomass enhances sound insulation, mechanical properties and processability. This method realizes resource recycling of waste biomass and overcomes the defects of traditional sound insulation materials, meeting noise reduction demands in multiple fields.
