| 中文摘要: |
| 通过机械共混法制备白炭黑/天然橡胶(NR)复合材料,研究分散剂B-52用量对白炭黑/NR复合材料性能的影响。结果表明:随着分散剂B-52用量的增大,复合材料的t10和t90呈现出先延长后缩短的趋势,结合胶含量和表观交联密度提高,综合物理性能先提高后有所降低;当分散剂B-52用量为2份时,复合材料的综合物理性能最佳。 |
| 英文摘要: |
| The silica/natural rubber(NR) composites were prepared by mechanical blending,and the effect of the addition level of dispersant B-52 on the properties of silica/NR composites was studied. The results showed that,with the increase of the addition level of dispersant B-52,the t10 and t90 of the composites were extended first and then shortened,bound rubber content and apparent cross-linking density increased,and comprehensive physical properties increased first and then decreased. The composites had the best comprehensive physical properties when the addition level of dispersant B-52 was 2 phr. |
