摘要
近年来,人们对纺织制品的功能化有了很大的需求,如柔软舒适度、防水、冰凉手感等.以异佛尔酮二异氰酸酯(IPDI)、六亚甲基二异氰酸酯(HDI)、亲水扩链剂二羟甲基丙酸(DMPA)、聚碳酸酯二元醇(AS-302)、有机硅改性剂(LPW 733)和多元胺等材料合成冰感水性聚氨酯树脂.利用红外光谱(FTIR)、静态水接触角测试仪、差示扫描量热法(DSC)和热失重测试(TGA)等仪器对水性聚氨酯进行表征,并对水性聚氨酯的性能进行研究.研究表明:当LPW 733添加量为预聚体质量10％时制备的水性聚氨酯胶膜吸水率为3.8％,静态接触角为87.6°,耐水煮和干、湿摩擦性能好,柔软度适中和冰感效果好.
Abstract
In recent years,there has been a great demand for the functionalization of textile products,such as softness,comfort,waterproofing,and a cool touch.Ice sensitive waterborne polyurethane resin was synthesized using materials such as isophorone diisocyanate(IPDI),hexamethylene diisocyanate(HDI),hydrophilic chain extender dihydroxymethylpropionic acid(DMPA),polycarbonate diol(AS-302),organosilicon modifier(LPW 733),and polyamines.Characterize waterborne polyurethane using instruments such as infrared spectroscopy(FTIR),static water contact angle tester,differential scanning calorimetry(DSC),and thermogravimetric analysis(TGA),and study the properties of waterborne polyurethane.Research has shown that when the amount of LPW 733 added is 10％by weight of the prepolymer,the water absorption rate of the waterborne polyurethane film prepared is 3.8％,the static contact angle is 87.6°,the water boiling resistance and dry/wet friction performance are good,the softness is moderate,and the ice feeling effect is good.
