中文摘要:
      从秸秆中清洁分离木质素，并对木质素进行甲基化改性和相容性改性，研究改性木质素绿色化学湿法混炼对橡 胶与橡胶助剂性能的影响。结果表明：用改性木质素以绿色湿法混炼工艺制备的生物橡胶可提高轮胎胶料的粘合性能、 耐磨性能和耐老化性能；用改性木质素以绿色湿法混炼工艺制备的生物基炭黑母胶、生物基白炭黑母胶、生物基碳纳米管 母胶可提高轮胎胶料的性能；木质素改性氧化锌和癸酸钴可分别等量替代未改性氧化锌和癸酸钴用于轮胎胶料中，可以 减量增效和降低成本。本技术有利于提升国产天然橡胶性能并实现秸秆高值化利用。
英文摘要:
      The lignin separated from straw was further modified by methylation and compatibility，and then the effect of green chemical wet mixing of the modified lignin on the properties of rubber compounds and rubber additives was investigated. The results showed that the adhesion property，wear resistance and aging resistance of the tire compound based on the bio-rubber prepared by green chemical wet mixing process with the addition of the modified lignin were improved. The properties of tire compounds were improved using the bio-based carbon black masterbatch，bio-based silica masterbatch and bio-based carbon nanotube masterbatch，respectively，which were prepared by the green chemical wet mixing process with the modified lignin. Lingin modified zinc oxide and cobalt decanoate could replace unmodified zinc oxide and cobalt decanoate in tire compounds in the same amount， respectively，leading to the reduction of the addition level of zinc oxide and cobalt decanoate，the improvement of the quality and the decreasing of the cost of the tire compounds. This technology was beneficial to improving the performance of domestic natural rubber and realizing the high-value utilization of straw.
