稻壳源白炭黑/炭黑/天然橡胶复合材料的性能研究

Properties of Rice Husk Silica/Carbon Black/NR Composites

试验研究稻壳源白炭黑/炭黑并用对天然橡胶硫化胶性能的影响。结果表明:当稻壳源白炭黑/炭黑用量比较高时,胶料的M_L较大,t_(10)较短,t_(90)较长,物理性能较差;当稻壳源白炭黑、炭黑用量较为均衡时,硫化胶的物理性能变化不大,动态力学性能较好;稻壳源白炭黑/炭黑用量比对硫化胶耐寒性能的影响不大;当稻壳源白炭黑/炭黑用量比为20/40和25/35时,硫化胶的综合性能较好。

The effect of rice husk silica/carbon black blend on the properties of NR compound was experimentally investigated. The results showed that,when the blending ratio of rice husk silica/carbon black was higher,the M_L of the compound was larger,t_（10） was shorter,t_（90） was longer,and the physical properties were poorer. When the blending ratio was balanced,the physical properties of the vulcanizate changed little,and the dynamic mechanical property was better. It was also found that the blending ratio had little effect on the low temperature properties of the vulcanizate. When the blending ratio was 20/40 or 25/35,the comprehensive properties of the vulcanizate were better.
