纳米氧化铝对天然橡胶/顺丁橡胶/丁苯橡胶复合材料性能的影响

摘要

Effects of amount of nano-aluminum oxide on properties and wet skid resistance on glass and asphalt pavement of natural rubber/cis-1,4-polybutadiene rubber/styrene-butadiene rubber composites were investigated.The results showed that no significant change in the mechanical properties and loss factor at 0 ℃ and 60 ℃ of the composites occurred,when the amount of nano-aluminum oxide was less than 10.0 phr.The wear resistance decreased and the heat build-up increased with the increase of nano-aluminum oxide amount.The wet skid resistance of the composites on the glass pavement improved with the increase of nano-aluminum oxide amount.While on the asphalt pavement,the amount of nano-aluminum oxide had no significant effect on the wet skid resistance of the composites,and the average structure depth of pavement became the main influence factor of the wet skid resistance.%研究了纳米氧化铝用量对天然橡胶/顺丁橡胶/丁苯橡胶复合材料的性能及在玻璃路面与沥青路面的抗湿滑性能的影响.结果表明,纳米氧化铝用量小于10.0份时,对复合材料的力学性能、0℃和60℃下的损耗因子影响不大,但随纳米氧化铝用量的增加,复合材料的耐磨性能下降,压缩生热增加.当摩擦面为玻璃路面时,随着纳米氧化铝用量的增加,复合材料的抗湿滑性能提高.当摩擦面为沥青路面时,纳米氧化铝的用量对复合材料的抗湿滑性能影响不大,路面的平均构造深度为抗湿滑性能的主要影响因素.
