摘　　要：以自制端环氧聚醚硅油和聚醚胺D-230为反应原料,在不添加溶剂的情况下制备聚醚氨基嵌段共聚硅油,并将其用于羊绒织物的后整理。研究反应温度、反应时间和反应物摩尔比对产物乳化性能的影响,通过傅里叶红外光谱、热重分析仪、纳米粒度仪和场发射扫描电子显微镜对聚醚氨基嵌段共聚硅油柔顺剂进行结构表征和形貌分析,并对其整理后羊绒织物的白度、亲水性及相对手感值进行测试,结果表明:无溶剂聚醚氨基嵌段共聚硅油的最佳合成工艺为:当反应温度为80℃,反应时间为6 h,自制端环氧聚醚硅油(Mw=8000)与聚醚胺D-230摩尔比为1∶1.4时,所制聚醚氨基嵌段共聚硅油环氧值最低;乳液带有蓝光,平均粒径为56.26 nm,粒径分散指数为0.046;经聚醚氨基嵌段共聚硅油乳液整理后的羊绒织物的亲水性和柔软性提高,白度基本不变。该嵌段共聚硅油具有优异的综合性能,具有重要的实用价值。Using self-made epoxy-terminated polyether silicone oil and polyether amine D-230 as raw materials,a solvent-free polyether amino block copolymer silicone oil is prepared without adding any solvent and it is used for the finishing of fleece fabrics.The effects of reaction temperature,reaction time,and molar ratio of reactants on the emulsification properties of the product were studied.Fourier infrared spectroscopy,thermogravimetric analyzer,nanoparticle size analyzer,and field emission scanning electron microscope were used to characterize the structure and analyze the morphology of polyether amino block copolymer silicone oil softener,and the whiteness,hydrophilicity and relative hand feel of finished fleece fabric were tested.The research results showed that the best synthesis process of solvent-free polyether amino block copolymer silicone oil was:when the reaction temperature was 80℃,the reaction time is 6 h,the molar ratio of self-made epoxy-terminated polyether silicone oil(Mw=8000)and polyether amine D-230 was 1∶1.4,the prepared polyether amino block copolymer silicone oil had the lowest epoxy value;the emulsion was a clear and transparent liquid with stable properties and blue light with an average particle size of 56.26 nm and a particle size dispersion index of 0.046.The hydrophilicity and softness of the subsequent fleece fabric finished by polyether amino block copolymer silicone oil emulsion were improved,and the whiteness was basically unchanged.The proposed block copolymer silicone oil has excellent comprehensive properties and important practical application value.
