| Abstract: |
| The ultrafine fully vulcanized powder SBR （UFPSBR）/nano-calcium carbonate （nano-CaCO3）/SBR nano-composites were prepared by UFPSBR/nano-CaCO3 compounded powder，and the properties of composites were investigated.The results showed that，as the addition level of UFPSBR/nano-CaCO3 compounded powder increased，the curing time of UFPSBR/nano-CaCO3/SBR nano-composites was shortened，curing speed was accelerated，physical properties and flame retardant property were improved，glass transition temperature was decreased，and storage modulus was increased. |
