有机硅改性水性聚氨酯增深剂的合成及应用
Synthesis and application of silicone modified waterborne polyurethane darkening agent
摘要
Abstract
Taking isophorone diisocyanate (IPDI) and polypropylene glycol (PPG) as raw material, polyure-thane prepolymer was synthesized under the catalysis of dibutyltin dilaurate (DBTDL). Cationic type of organic silicon modified waterbome polyurethane emulsion was prepared through the modification of the prepolymer with 3-aminopropyltriethoxysilane (KH-550) and through the chain extension with 1,4-butanediol (BDO) and triethanolamine (TEA). The effects of R value [n(-NCO)/n(-OH)], w(KH-550), and w(TEA) on the performance of emulsion were discussed. The structure and properties of the darkening agent were characterized by FT-IR, 1H-NMR and Zeta potential. The properties of the cotton fabrics and silk fabrics finished with the darkening agent were tested. The results showed that the deepening ratio of the black cotton fabrics and silk fabrics were 19.73% and 17.49%, respectively. The dry and wet rubbing fastness were both increased over half level. And the darkening effect of the finished fabrics had good washing durability.关键词
