Abstract:
      The silica was prepared by arginine-assisted process（referred to as homemade silica）.The silica/natural rubber（NR） nanocomposites was prepared by mixing and coagulating of silica dispersion with natural latex. The reinforcing effect of silica on NR was investigated. The results showed that，compared with ordinary silica，the homemade silica had higher monodispersity，more uniform distribution and higher degree of dispersion in NR. Compared with ordinary silica/NR nanocomposites，the curing rate of homemade silica/NR nanocomposites was accelerated，and the strength was significantly improved，in which the tensile strength was increased by 13.6%，and the tear strength was increased by 8.8%.
