研究炭黑N234和热解炭黑(CBp)补强天然橡胶(NR)/顺丁橡胶(BR)并用胶的性能,以及炭黑N234补强和CBp与碳纳米管(CNTs)协同补强溶聚丁苯橡胶(SSBR)/NR并用胶的性能。结果表明:相比于炭黑N234,CBp可以延迟胶料的硫化;与炭黑N234补强NR/BR并用胶相比,CBp补强NR/BR并用胶60 ℃时的损耗因子(tanδ)显著减小,说明CBp可以一定程度上降低NR/BR并用胶的滚动阻力;在CBp与CNTs协同补强SSBR/NR并用胶中,CNTs对SSBR/NR并用胶的补强作用明显;30份CBp与2份CNTs协同补强SSBR/NR并用胶的综合物理性能与20份炭黑N234补强SSBR/NR并用胶相当,且0 ℃时的tanδ增大,说明CNTs可以改善SSBR/NR并用胶的抗湿滑性能。 |
英文摘要: |
The properties of pyrolytic carbon black(CBp) reinforced natural rubber(NR)/butadiene rubber(BR) blend and CBp and CNTs synergistically reinforced solution-polymerized polystyrene-butadiene rubber(SSBR)/NR blend were investigated,and compared with carbon black N234 reinforced NR/BR blend and SSBR/NR blend,respectively.The results showed that,compared with carbon black N234,CBp could delay the vulcanizations of the compounds.Compared with carbon black N234 reinforced NR/BR blend,the tanδ at 60 ℃ of CBp reinforced NR/BR blend was significantly smaller,indicating that CBp could reduce the rolling resistance of NR/BR blend to a certain extent.In CBp and CNTs synergistically reinforced SSBR/NR blend,the reinforcement effect of CNTs on SSBR/NR blend was obvious.The comprehensive physical properties of 30 phr CBp and 2 phr CNT synergistically reinforced SSBR/NR blend were equivalent to those of 20 phr carbon black N234 reinforced SSBR/NR blend,and the tanδ at 0 ℃ increased,indicating that CNTs could improve the wet skid resistance of SSBR/NR blend. |
