| Abstract: |
| The alkali lignin/straw powder/rubber composites were prepared by mechanical mixing method，and their properties were investigated.The results showed that，in the alkali lignin and straw powder blend，as the additional level of alkali lignin increased，the Mooney viscosity of the compound increased，the crosslinking degree decreased and optimum cure time was extended. At the same time，the hardness and rebound value of the vulcanizate decreased，the tensile strength and elongation at break increased，the wear resistance was improved，and low temperature resistance changed little. When the blend ratio of alkali lignin/straw powder was 2∶1，the tensile strength of the composites reached the maximum value，and the wear resistance was the best. |
