摘要
木质素是地球上最丰富的生物材料之一,其基本单元为9-碳苯酚丙烷(香豆醇、松柏醇和芥子醇),这些单元通过不同类型的键连接在一起形成一个多酚类芳香族聚合物。作为造纸工业的主要废弃物,木质素成本低廉,目前主要用作低附加值的燃料,其开发价值还没有得到充分利用。将木质素用于填充改性橡胶既经济又环保,其不仅有补强的效果,还有偶联、抗氧防老、阻燃的作用,可部分代替炭黑。本文将对木质素的改性、橡胶/木质素复合材料的制备方法及研究进展进行综述,并对橡胶/木质素复合材料研究的挑战和机遇进行了展望。
Lignin,one of the most abundant biopolymers on earth,is a polyphenolic macromolecule which is comprised of 9-carbonphenol propane units(p-coumaryl alcohol,coniferyl alcohol,and sinapyl alcohol)linked together by different types of bonds.Large amounts of lignin have been generated by the pulp and paper industry through kraft process.Lignin is mainly used as a low-grade fuel and its potential is not fully valued.It is economically and environmentally desirable to convert lignin to valuable reinforcing additives for rubbers.Lignin can be used as coupling agent,antiaging agent,fire retardant as well as reinforcing agent,and it could partially replace carbon black in the rubber composites.Modification of lignin,various preparation methods of rubber/lignin composites and recent research progress are systematically reviewed in this article.Lastly,the challenges and future potentials of rubber/lignin composites are proposed.
