摘要
阐述聚氨酯的组成和热降解行为;列举聚氨酯耐高温改性的方法,分析纳米二氧化硅的作用机理、有机硅的改性原理以及有机硅、硅烷偶联剂改性蓖麻油聚氨酯形成聚合物互穿网络的方法;综述硅改性聚氨酯的耐高温性能的方法和研究进展。
This paper is to examine the thermal degradation behaviour of polyurethane.Specifically,the mechanisms of action of nano-SiO 2 and the modification principles of organosilicon are to be analysed.The study also investigates the modification of castor oil polyurethane by organosilicon and silane coupling agent to form a polymer interpenetrating network for polyurethane s high-temperature resistant modification.Furthermore,the paper reviews methods of high-temperature resistant performance of silicone-modified polyurethanes and the current research progress in this area.
