Abstract:
      The modified graphene oxide（GO） was prepared by the Hummers method and using silane coupling agent KH-550 as modifier，the modified GO/IIR composites was prepared by using modified GO as reinforcing filler and using butyl rubber（IIR） as rubber matrix，and the properties of composites were investigated.The results showed that the tensile strength of the composites adding modified GO first increased and then decreased，the loss factor peak increased，the damping temperature range was widened， and the sound insulation performance was slightly improved.The composites could effectively suppress the resonance and coincidence effects of single-layer galvanized steel sheet，and the sound insulation performance of the constrained damping sound insulation board prepared based on the damping characteristics of composites was significantly improved.
