植物油基水性聚氨酯的研究进展

Progress in Vegetable Oil Based Waterborne Polyurethanes

近年来,以植物油作为一种典型的可再生资源来开发生物基水性聚氨酯(WPU)受到产业界和科技界的重视。文中以植物油甘油三酯为基础碳链结构,从分子结构设计和合成WPU所需的单体化合物,绿色制备植物油基WPU以及对WPU的性能改性策略等方面进行了全面总结。并结合国内外WPU的发展水平,展望了植物油基WPU的发展方向和应用前景。

With the rapid depletion of petroleum feed stock and increasing attention to sus tainable development and environmental protection, vegetable oils based WPUs with renewable resources as raw materials has attracted more and more attentions. As a typical renewable resource, using vegetable oils as the platform compound to develop WPU has become the focus in industry and science sectors. In this article, the recent advance of the WPU using vegetable oil triglyceride as the basic carbon chain structure via the molecular structure design and preparation of monomer compounds for WPUs preparation has been summarized. Furthermore, the green synthesis of vegetable oil based WPUs and their modification strategy were summarized. The development trends and application prospects of vegetable oil based WPUs were presented according to the development of WPUs at home and abroad.
