Synthesis, Characterization and Application of Waterborne Polyurethane Crosslinker
摘要
Abstract
A novel waterborne polyurethane ( WPU) crosslinker, 5-bis(/3-hydroxyethyl) amino-2-pentanone (BHAP), was synthesized from diethanolamine ( DEA) and 5-chloro-2-pentanone(CPE), and characterized by means of FTIR, NMR and MS. The effects of reaction temperature, reaction time, solvent, catalyst and acid binding agent on the yield of BHAP were investigated. The results showed that under the optimal reaction conditions of dimethylformamide as the solvent, Na2CO3 as the acid binding agent, Nal as the catalyst, reaction temperature 73 t and reaction time 30 h, the yield and the purity of BHAP were 90.74% and 89. 66% , respectively. After BHAP was linked to the main chain of WPU, the properties of the WPU latex films were studied. Compared with the non-crosslinked WPU, under BHAP dosage (mass fraction in the modified WPU latex film) 7% , the water absorption and the toluene absorption of the WPU latex films modified by BHAP decreased by 64. 70% and 15.12% respectively, and their tensile strength and gel mass fraction increased by 11. 81 Mpa and 4.43% respectively.关键词
