| 中文摘要: |
| 简述稻壳灰白炭黑生产的环保优势，研究稻壳灰白炭黑性能及其在轿车轮胎胎面胶中的应用，并与高分散性白炭黑、易分散性白炭黑和普通白炭黑进行对比。结果表明：稻壳灰白炭黑纯度高，比表面积小，其他理化性能与高分散性白炭黑差异不大，造粒程度高；稻壳灰白炭黑的宏观形貌、微观形貌与高分散性白炭黑一致，激光粒径分布与高分散性白炭黑相近，分散性明显优于易分散性白炭黑和普通白炭黑；稻壳灰白炭黑胶料在混炼过程中的升温速率、混炼时间和门尼粘度均与高分散性白炭黑胶料接近，加工性能优于易分散性白炭黑和普通白炭黑胶料；稻壳灰白炭黑胶料的硫化特性和物理性能与高分散性白炭黑胶料基本相当；稻壳灰白炭黑胶料的动态力学性能与高分散性白炭黑、易分散性白炭黑和普通白炭黑胶料无明显差异；稻壳灰白炭黑胶料的耐屈挠性能较好，与高分散性白炭黑胶料相近。 |
| 英文摘要: |
| In this paper，the environmental advantages of rice husk ash silica production was briefly presented，the performance of rice husk ash silica and its application in the tread compound of the PCR tire were studied and compared with highly dispersible silica，easily dispersible silica and regular silica. It was found that the rice husk ash silica possessed a high purity，low specific surface area and high degree of granulation. It showed similar physical and chemical properties as highly dispersible silica，and they had the same macroscopic morphology and microstructure，and similar laser diffraction particle size distribution. The dispersion of rice husk ash silica was better than that of easily dispersible silica and regular silica. The temperature increase rate，mixing time and Mooney viscosity of rice husk ash silica filled compound were close to those of highly dispersible silica filled compound，and the processing properties were better than those of easily dispersible silica or regular silica filled compound. The vulcanization properties and physical properties of rice husk ash silica filled compound were also similar to those of highly dispersible silica filled compound. The dynamic mechanical properties of rice husk ash silica filled compound were not significantly different from those of highly dispersible silica，dispersible silica and regular silica filled compounds. The flex resistance of the rice husk ash silica filled compound was good as that of highly dispersible silica filled compound，and was similar as that of highly dispersible silica filled compound. |
