中文摘要:
      将硅烷偶联剂KH550改性木质素与硅烷偶联剂KH560改性白炭黑（SiO2）接枝聚合制备木质素接枝SiO2杂化填料（记为木质素@SiO2），并采用绿色化学湿法混炼工艺制备木质素@SiO2/天然橡胶（NR）复合材料，研究木质素@SiO2的木质素/SiO2用量比对木质素@SiO2/NR复合材料性能的影响。结果表明：随着木质素@SiO2的木质素/SiO2用量比的增大，木质素@SiO2/NR复合材料的t10和t90缩短，邵尔A型硬度呈减小趋势；木质素/SiO2用量比为6/9的木质素@SiO2/NR复合材料的拉伸强度最大和DIN磨耗量最小，分别为27.6 MPa和101.42 mm3；木质素/SiO2用量比为12/3的木质素@SiO2/NR复合材料的拉断伸长率最大和撕裂强度较大，分别为587%和83 kN·m-1；热空气老化后木质素@SiO2/NR复合材料的拉伸强度变化率和拉断伸长率变化率绝对值呈减小趋势。木质素/SiO2用量比为3/12的木质素@SiO2/NR复合材料的抗湿滑性能较好，滚动阻力较小。
英文摘要:
      The lignin grafting silica（SiO2） hybrid filler（recorded as lignin@SiO2） was prepared by grafting polymerization of lignin modified with silane coupling agent KH550 and SiO2 modified with silane coupling agent KH560.The lignin@SiO2/natural rubber（NR） composites were prepared using green chemical wet mixing process，and the effect of lignin/SiO2 dosage ratios of the lignin@SiO2 on the lignin@SiO2/NR properties was studied.The results showed that，with the increasing of lignin/SiO2 dosage ratio of the lignin@SiO2，the t10 and t90 of the lignin@SiO2/NR composite were shortened，the Shore A hardness presented a decreasing trend.The lignin@SiO2/NR composite with lignin/SiO2 dosage ratio of 6/9 had the largest tensile strength and the smaller DIN wear，which were 27.6 MPa and 101.42 mm3，respectively.The lignin@SiO2/NR composite with lignin/SiO2 dosage ratio of 12/3 had the largest tensile elongation and larger tear strength，which were 587% and 83 kN·m-1，respectively.The absolute values of the tensile strength change rate and elongation at break change rate of the lignin@SiO2/NR composite showed a decreasing trend after hot air aging.The lignin@SiO2/NR composite with lignin/SiO2 dosage ratio of 3/12 had better wet slip resistance and lower rolling resistance.
