摘要
针对聚氨酯水分散液(PUD)胶膜目前存在的耐热、耐水性能的不足,介绍了用聚硅氧烷(PSi)改性的研究进展。综述了硅氧烷改性聚氨酯水分散液(PSi-PUD)的特性、难度及其克服的措施。简略叙述了理论依据。
Aimed at recently existing drawbacks of insufficient heat resistance and water-resistance of films formed from polyurethane aqueous dispersions（PUD）,the research progresses of their modifications with siloxanes（PSi） are introduced.The characteristics,difficulties and their overcoming measures of PSi-PUD are reviewed.The theoretical base is outlined briefly.
