摘要
采用高沸醇（HBS）木质素制备得到了HBS木质素／纳米SiO2复合材料。对产物进行红外光谱、透射电镜分析，可以明显看出材料复合后的特征，表明木质素／无机纳米复合材料的制备是可行的。把木质素／纳米SiO2复合材料作为橡胶的补强剂应用于乙丙橡胶。实验发现，HBS木质素／纳米SiO2复合材料添加到橡胶中可提高胶料的断裂伸长率，从165％提高到229％，但拉伸强度略有降低。
Complex material of HBS lignin/nanometer silica was be prepared by high boiling solvent lignin and nanometer silica. The products were characterized by infrared spectrum and transmission electron microscope（TEM）. The results indicated that it is feasible to prepare with the composite of lignin/nanometer inorganic material. The composite of lignin/nanometer silica could b used as the reinforcing agent in the ethylene-propylene rubber. The breaking elongation of the rubber was increased from 165% to 229%, when the complex material of lignin/nanometer silica was added in the rubber, the tensile strength was reduced.
