%X 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。;The silica/natural rubber（NR） composites were prepared by mechanical blend，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 were increased，and comprehensive physical properties were first increased and then decreased.The composites had the best comprehensive physical properties when the addition level of dispersant B-52 was 2 phr
