摘　　要：研究混炼工艺对含白炭黑的天然橡胶胎面胶硅烷化反应的影响,进而研究其对胶料各项性能的影响。结果表明:白炭黑与硅烷偶联剂的硅烷化反应温度集中在135~150℃区间内,随着有效硅烷化反应时间的延长,硫化胶的损耗因子减小,生热降低,滞后性能改善;当混炼温度达到150℃后,有效硅烷化反应时间对硫化胶的生热和滞后性能影响变小;白炭黑良好的硅烷化反应有利于提高硫化胶的耐磨性能。The effect of mixing process on the silylation reaction of silica filled natural rubber tread compound was studied,and its effect on the properties of the compound was investigated.The results showed that the silylation reaction temperature of silica and silane coupling agent was concentrated in the range of 135~150℃.With the extension of the effective silylation reaction time,the loss factor and heat build-up of the vulcanizate decreased,and the hysteresis property was improved.When the mixing temperature reached 150℃,the effective silylation reaction time had less effect on the heat build-up and hysteresis properties of the vulcanizates.The good silylation reaction of silica was beneficial to improve the wear resistance of the vulcanizates.
