聚氨酯木材胶黏剂的研究进展

Research Progress of Polyurethane Wood Adhesives

木材是人们生产生活中不可或缺的材料之一,在木材制品的生产过程中往往要应用到胶黏剂。在众多木材胶黏剂中,聚氨酯(PU)胶黏剂由于无甲醛释放,目前被认为是最绿色环保的胶黏剂之一。随着中国经济的发展,带动PU工业的飞速前行,目前中国已经成为PU原料的生产大国。开发更广更深的应用市场是PU工业未来发展的必然趋势,这些条件为我国PU木材胶黏剂的开发及产业化奠定了良好的基础。鉴于此,首先对聚氨酯木材胶黏剂进行了简要分析,然后阐述了PU基木材胶黏剂的研究和应用现状。

Wood is one of the indispensable materials in production and life. It is often applied to adhesives in the production of wood products. Among many wood adhesives,polyurethane(PU)adhesives are currently considered to be one of the most environmental friendly adhesives due to formaldehydefree. With the development of economy and the rapidly advancing of PU industry, China has become a major producer of PU raw materials. Developing a deeper and broader application market is an inexorable trend for the future development of PU industry. These conditions have laid a good founda-tion for the development and industrialization of PU wood adhesives in China. In view of this, polyurethane wood adhesives is analyzed briefly and the research progress and application status of PU wood adhesives are related.
