摘要
聚氨酯综合性能优异,是日常生活和工业中最常用的聚合物材料之一.传统的聚氨酯主要是由多元醇和剧毒的二异氰酸酯或多异氰酸酯的反应来制备.在当前可持续发展的背景下,非异氰酸酯路线合成功能性聚氨酯因制备过程中不使用有毒的异氰酸酯原料,同时又能够满足市场多样化和人们日益增长的功能需求而备受重视.本综述总结了具有应用前景的非异氰酸酯路线制备聚氨酯,详细介绍了以环碳酸酯和碳酸二甲酯为原料的反应路线及其优缺点,并对功能性非异氰酸酯聚氨酯在自修复、形状记忆、可再加工和可粘接性等功能领域的应用研究进展进行了详细探讨,最后对其未来发展方向和趋势进行了展望.
Abstract
Polyurethanes are among the most commonly used polymeric materials in daily life and industry due to their excellent combined properties.Conventional polyurethanes are mainly prepared by the reaction of polyols and highly toxic diisocyanates or polyisocyanates.In the current context of sustainable development,functional non-isocyanate polyurethanes are highly valued because they are prepared without the use of toxic isocyanate raw materials,and at the same time,they can meet the growing demand and market variety.In this review,the preparation routes of non-isocyanate polyurethanes with application prospects were summarized,and reaction routes based on cyclic carbonate and dimethyl carbonate,as well as their advantages and disadvantages,were discussed in detail.The application progress of functional non-isocyanate polyurethanes in fields of self-healing materials,shape memory materials,reprocessable materials and adhesion was also discussed in detail,and the future development direction and trend were prospected.
