摘　　要：研究偶联剂Si69对乳液共沉法生成白炭黑/NR复合材料性能的影响。结果表明,在乳液共沉法生成白炭黑的反应中加入偶联剂Si69,可以增强白炭黑粒子与NR基体之间的界面作用,改善白炭黑在NR中的分散状态,提高复合材料的物理性能和混炼胶的动态力学性能;偶联剂Si69的适宜用量为3份。The effect of coupling agent Si69 on the properties of silica/NR composites prepared by emulsion co-coagulation method was investigated. The results showed that, by adding coupling agent Si69 in the reaction which produced silica,the boundary interaction between silica and NR matrix was increased, the dispersion of silica in NR matrix was improved,and the physical properties of composites and dynamic property of compound were improved;the optimum addition level of coupling agent Si69 was 3 phr.
