白炭黑/纳米甲壳素/多层石墨烯对溶聚丁苯橡胶/顺丁橡胶并用胶性能的影响

将白炭黑、纳米甲壳素与多层石墨烯三者并用填充溶聚丁苯橡胶(SSBR)/顺丁橡胶(BR)并用胶,考察了多层石墨烯用量对并用胶硫化特性、物理机械性能、耐老化性能及Payne效应的影响。结果表明,加入多层石墨烯后,SSBR/BR混炼胶的焦烧时间及正硫化时间明显缩短,硫化速率加快,加工性能得到改善;随着多层石墨烯用量的增加,SSBR/BR硫化胶的拉伸强度略提高后降低,100%定伸应力及300%定伸应力逐渐降低,扯断伸长率增大,撕裂强度及邵尔A硬度变化不大;经热空气老化后,SSBR/BR硫化胶的拉伸强度变化率明显降低,综合考虑,多层石墨烯最佳用量为1.0份;随着多层石墨烯用量的增加,SSBR/BR混炼胶...

Summary:将白炭黑、纳米甲壳素与多层石墨烯三者并用填充溶聚丁苯橡胶(SSBR)/顺丁橡胶(BR)并用胶,考察了多层石墨烯用量对并用胶硫化特性、物理机械性能、耐老化性能及Payne效应的影响。结果表明,加入多层石墨烯后,SSBR/BR混炼胶的焦烧时间及正硫化时间明显缩短,硫化速率加快,加工性能得到改善;随着多层石墨烯用量的增加,SSBR/BR硫化胶的拉伸强度略提高后降低,100%定伸应力及300%定伸应力逐渐降低,扯断伸长率增大,撕裂强度及邵尔A硬度变化不大;经热空气老化后,SSBR/BR硫化胶的拉伸强度变化率明显降低,综合考虑,多层石墨烯最佳用量为1.0份;随着多层石墨烯用量的增加,SSBR/BR混炼胶的Payne效应逐渐下降,而硫化胶的Payne效应变化不大。

Solution-polymerized styrene-butadiene rubber ( SSBR )/cis-1, 4-butadiene rubber ( BR ) blends were filled with silica/nano ehitin/multilayer graphene, and the effects of amount of muhilayer gra- phene on curing characteristics, mechanical proper- ties, aging resistance and Payne effect of the blends were investigated. The results showed that the multi- layer graphene could shorten the scorch time and cu- ring time, accelerate the rate of vulcanization, and improve processability of SSBR/BR compounds. With increasing amount of muhilayer graphene, the tensile strength of the vulcanizates slightly increased first and then decreased, modulus at 100% and modulus at 300% decreased,
