超细全硫化粉末丁苯橡胶/纳米碳酸钙复合粉末对丁苯橡胶性能的影响

采用超细全硫化粉末丁苯橡胶（UFPSBR）/纳米碳酸钙复合粉末制备UFPSBR/纳米碳酸钙/丁苯橡胶（SBR）纳米复合材料，并对其性能进行研究。结果表明：随着UFPSBR/纳米碳酸钙复合粉末用量的增大，UFPSBR/纳米碳酸钙/SBR纳米复合材料的硫化时间缩短、硫化速率加快、物理性能和阻燃性能提高，同时玻璃化温度下降、储能模量增大。;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
