水性聚氨酯材料的改性研究进展OA

With the advancement of the concept of sustainable development and the enhancement of global environmental awareness,waterborne polyurethane material,as a green and high-performance material,satisfies the increasingly strict requirements for environmental friendliness,and has received extensive attention in industrial production.However,waterborne polyurethane materials still have obvious deficiencies in water re-sistance,mechanical properties and thermal stability,which seriously limits the production and development of waterborne polyurethane industry.This paper reviews six main modification methods of waterborne polyurethane materials.It includes organosilicon modification,organic fluorine modification,isocyanate oligomer modification,nano-inorganic material modification,crosslinking agent modification and polymer blending modi-fication.The research progress of different modification methods is summarized,and the future prospects of waterborne polyurethane materials are forecast.
