稻壳源白炭黑对天然橡胶胶料动态性能的影响

Effect of Silica Originated from Rice Hull on Dynamic Properties of NR Compound

研究稻壳源白炭黑的结构及其对天然橡胶(NR)胶料动态性能的影响。结果表明:稻壳源白炭黑的粒径小,比表面积大,分散性较好;随着稻壳源白炭黑用量的增大,NR混炼胶的Payne效应越来越明显,硫化胶的损耗因子呈增大趋势。

The structure of the silica originated from rice hull and its effect on the dynamic proper- ties of NR compound were investigated. The results showed that,the particle size of the silica origina- ted from rice hull was small, the specific surface area was large, and the dispersity was good. As the ad- dition level of silica increased, the Payne effect of NR compound became more and more obvious, and the loss factor of NR vulcanizate tended to increase.
