本文采用钛酸酯系列偶联剂对造纸工业废渣──木质素磺酸盐进行处理，然后填充聚氯乙烯（PVC）制成复合材料．结果发现用钛酸酯类偶联剂处理的木质素磺酸盐，填充PVC体系，其拉伸强度随使用钛酸酯偶联剂不同，拉伸强度下降幅度不同，而冲击强度和伸长率都不同程度上升，尤以冲击强度的提高最为明显． In this paper, a titanate series coupling agent was used to treat lignosulfonates, a paper industry waste residue, and then filled with polyvinyl chloride (PVC) to form a composite material. As a result, it was found that the lignosulfonates treated with the titanate-based coupling agent are filled in the PVC system, and the tensile strength decreases with the use of the titanate coupling agent, whereas both the impact strength and the elongation Different degrees of increase, especially in the impact of the most obvious increase.
