端羟基超支化聚(胺-酯)复鞣剂的合成与应用性能研究
Study on synthesis and application properties of hydroxyl-terminatedhyperbranched poly(amine-ester) retanning agent
摘要
Abstract
AB2 monomer was synthesized by Michael addition of diethanolamine (DEA) and methyl acrylate (MA).Then the hydroxyl-terminated hyperbranched poly (amine-ester) with different generations (HPAE-I,HPAE-II and HPAE-III) was prepared respectively via transesterification of trimethylolpropane (TMP) and AB2 monomer in which TMP was used as the core and AB2 monomer as the branching unit.The structure of HPAEs were characterized by Fourier Transform Infrared Spectra (FT-IR) and Gel Permeation Chromatography (GPC).HPAEs with different generations as retanning agents were applied in the retanning process of wet blue leather.The application results show that when the dosages of HPICEs retanning agent is 3% (basing on the weight of wet blue leather),the properties of leather retanned with HPAE-III are better than that of HPAE-I and HPAE-II.The thickening rate of the back and belly are 14.88% and 19.51%,respectively.Meanwhile,the mechanical properties were obviously better than that of leather retanned with RST.Compared with that of leather retanned with RST,the tearing strength of the back and belly of leather retanned with HPAE-III are increased by 46.20% and 67.12%,the tensile strength of bake and belly are increased by 65.57% and 72.15%.The dry-rub fastness of leather retanned by HPAEs with different generations nearly is the same,the wet-rub fastness of leather retanned by HPAE-I is as same as that of leather retanned by RST,and they are both better than those of leather retanned with HPAE-II and HPAE-III.关键词
