摘　　要：研究排胶温度和时间对炭黑/白炭黑/偶联剂Si69补强体系中白炭黑硅烷化反应程度和胶料性能的影响。结果表明,当排胶温度为155℃、排胶时间为280~320 s时,炭黑/白炭黑/偶联剂Si69补强体系混炼胶中白炭黑的硅烷化反应程度最高,填料分散性较好,胶料的综合性能最佳。The effects of discharge temperature and time on the silanization reaction degree of silica and properties of the compound with carbon black/silica/coupling agent Si69 reinforcement system were studied.The results showed that when the discharge temperature was 155℃and the discharge time was 280~320 s,the silanization reaction degree of silica in the compound was the highest,the filler dispersion was good,and the comprehensive properties of the compound was the best.
