碳纳米管/SSBR复合材料的制备与性能研究

采用环保型抑菌、杀菌剂BCT-2与NH3复配作为鲜胶乳的新型复合保存剂，研究其对鲜胶乳保存效果、生胶六项指标，混炼胶硫化特性以及硫化胶物理机械性能的影响。结果表明，复合保存剂BCT-2/NH3对鲜胶乳的保存效果优于NH3和NH3+TT/ZnO，保存144h后挥发脂肪酸值在0.05左右，粘度在10mPa·s左右，pH值高于9.0；生胶的P0、PRI及MV均小于氨保存；随着BCT-2的加入，混炼胶样品的ML、MH、t10、t90与氨保存胶料相比均有一定程度的降低；而复合保存剂BCT-2/NH3对硫化胶物理机械性能的影响不大。

Study on the Preparation and Properties of Carbon Nanotube/SSBR Nanocomposites

BCT-2 was an antibacterial and bactericide of environment friendly, that was chosen to compound with ammonia and used as a new compound preserving agent for fresh latex. The preservation effect and influence of that on the properties of the six indexes of raw rubber and the vulcanization characteristics of rubber compound and the physical and mechanical properties of cross-linked rubber were investigated in the paper. The result showed that BCT-2/NH3 compound preservative preserved effect were better than NH3 and NH3+TT/ZnO. After preserving 144 hours, the volatile fatty acid number (VFA NO.) were about 0.05, the viscosities were about 10 mPa·s, the pH value were above 9.0. The P0, PRI and Mv of raw rubber were lower than that preserved with ammonia. With the addition of BCT-2, the ML, MH, t10 and t90 of compound samples dropped in some extent compared with ammonia preserved one. While BCT-2/NH3 compound preservative had little effect for the physical and mechanical properties of cross-linked rubber.
