有机硅改性没食子酸非异氰酸酯聚氨酯的制备及性能研究
Synthesis and Properties of Gallic Acid-based Non-isocyanate Polyurethanes Modified with Polysiloxane
摘要
Abstract
A cyclic carbonate-functionalized polysiloxane (CCPS) was successfully synthesized by hydrosilylation of poly (methylhydrosiloxane) (PMHS) with allyl glycidyl carbonate(AGC) by using H2PtCl6as catalyst. The CCPS was subsequently incorporated into gallic acid-based non-isocyanate polyurethane (GNIPU) networks to form GNIPU-CCPS composites. The chemical structure of CCPS was characterized by FT-IR, 1H NMR and 13C NMR,as well as,the effects of CCPS on mechanical and thermal properties of GNIPU were investigated. The GNIPU-CCPS coatings exhibited excellent properties such as flexibility (0.5 mm),adhesion(grade 1) and impact strength(≥50 kg·cm). Furthermore,with the increase of CCPS content,the thermal stability,flexibility and water resistance of the coatings were increased,while the glass transition temperature and pencil hardness of the coatings were decreased.关键词
