| 中文摘要: |
| 采用乳液共沉法制备天然橡胶（NR）/生化木质素（BCL）复合材料，研究BCL/炭黑（CB）和BCL/白炭黑补强填充体系对复合材料性能的影响。结果表明：加入BCL使混炼胶的硫化时间均延长，NR/BCL/CB混炼胶的焦烧时间延长、硫化程度降低，NR/BCL/白炭黑混炼胶则焦烧时间缩短，硫化程度提高；加入BCL，NR/BCL/CB混炼胶的储能模量（G′）减小，而NR/BCL/白炭黑混炼胶的G′增大，但均不会严重损害硫化胶的物理性能；复合材料的抗湿滑性能提高，但滚动阻力增大。 |
| 英文摘要: |
| The natural rubber/biochemical lignin（NR/BCL） composites were prepared via emulsion coprecipitation method，and the effects of BCL/carbon black（CB） and BCL/silica reinforcement systems on the properties of the composites were studied.The results showed that the optimum curing time of the compounds were both extended by adding BCL，the scorch time of NR/BCL/CB compound extended and the degree of vulcanization decreased，but the scorch time of NR/BCL/silica compound was shortened and the degree of vulcanization increased.By adding BCL，the storage modulus（G′） of NR/BCL/CB compound decreased，while the G′ of NR/BCL/silica compound increased，but it did not seriously impair the physical properties of the vulcanizates；the wet skid resistance of the composites was improved，but the rolling resistance increased |
