无胶秸秆基纤维板的研究进展

Research progress of glue-free fiberboard based on straw

无胶秸秆基纤维板是生物质复合材料,具有无毒、可降解、可回收和可再生等特点。因其不消耗石油资源,有利于可持续发展,可替代部分木材应用于地板、建筑材料、家具、室内装修等领域。但对其制板机制及工艺的研究较欠缺,导致市场份额占比仍较低。本文综述了无胶秸秆基纤维板的自粘结机制和应用现状,分析了近年来无胶秸秆基纤维板的工艺进展,着重从纤维的预处理、纤维尺寸、工艺参数(压制时间、压力和温度)对无胶秸秆基纤维板性能的影响进行了系统综述,并对未来无胶秸秆纤维板的优化设计、大规模生产及推广应用进行了展望。

Glue-free straw-based fiberboard is a biomass composite material,which is nontoxic,degradable,recyclable and renewable.As it does not consume petroleum resources,it is conducive to sustainable development,and can replace some wood used in fields such as flooring,building materials,furniture and interior decoration.However,there is a lack of research on its board making mechanism and process,resulting in a still low market share.In this paper,the self-bonding mechanism and application status of glue-free straw-based fiberboard are summarized.The technological progress of glueless straw-based fiberboard in recent years is introduced.The effects of fiber pretreatment,fiber size and process parameters(such as pressing time,pressure and temperature)on the performances of glueless straw-based fiberboard are systematically discussed.The future prospect of glueless straw-based fiberboard in optimal design,industrial production and promotion on a large scale are put forward.
