▎ 摘　　要

NOVELTY - Environmentally-friendly regenerative sound insulation filter cotton comprises damping vibration damping sheet (1), porous non-woven gasket (2), regenerative polyvinyl chloride plastic cloth (3), honeycomb elastic resin net (4), aluminum alloy wire (5), and regenerative cotton fiber cloth (6). The porous nonwoven pad comprises 30-45 wt.% regenerated cotton short fiber, 30-40% rare earth-graphene composite modified synthetic epoxy resin, 5-15% modified graphene-p-phenylene benzobisoxazole ultra-short fiber, 5-15% modified graphene polyimide ultra-short fibre, 5-10% ceramic ultra-short fibre, 5-10% organic rare earth, 2-5% oxide graphene. USE - The sound insulation filter cotton is useful for automobile interior trim, engine cabin, passenger cabin, luggage and other parts. ADVANTAGE - The regenerative fiber cotton is capable of effectively sound insulation and filtering, damping and high elastic damping, environment-friendly regenerative sound insulation filter cotton for automobile interior and has excellent market application value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of environment-friendly regenerative sound insulation filter cotton for automobile interior trim. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of sound insulation filter cotton. 1Damping damping sheet 2Porous non-woven liner 3Regenerating pvc plastic cloth 4Honeycomb elastic resin net 5Aluminium alloy wire 6Regenerated cotton fibre cloth
