木质纤维材料的热塑性改性与塑性加工研究进展

Progress in Thermoplasticization and Plasticity-Processing of Lignocellulosic Materials

20世纪70年代,研究者们开始致力于将木质纤维材料转化为热塑性材料的改性研究,近年来进一步提出木质纤维材料塑性加工的学术理念并开展相关研究。本文简要综述木质纤维材料的热塑性改性研究进展和木质纤维材料塑性加工相关的材料特性。从深入分析木质纤维材料的黏弹性及其与主要组分的结构性质关系出发,阐述在基本保持木质纤维材料优良性能的前提下进行塑性加工的基本原理,并进一步提出通过动态塑化和木塑复合等方法实现塑性加工之可能的技术途径,为木质纤维材料资源的高效利用探索新的加工生产方式。

Considerable efforts of modification research have been made to convert lignocellulosic materials into thermoplastic materials since the late 1970s, while a new concept of the plasticity-processing of lignocellulosic materials was suggested by the scientists in the recent years, and the related investigations have been performed. In this paper, the progress of modification research on the thermoplasticization of lignocellulosic materials and the characteristic properties related to plasticity-processing was reviewed. In view of the relationship between the viscoelasticity and its structure-properties of the main components of lignocellulosic materials, the basic principle of plasticity-processing of lignocellulosic materials was discussed. The possible technical route for the plasticity-processing of lignocellulosic materials was further put forward by means such as the dynamic plasticization of lignocellulosic materials and the subsequent lignocellulosics-plastic compounding. This may open a different way of the processing of lignocellulosic material resources for its effective utilization.
