线性聚醚嵌段氨基硅油的制备及其性能

为简化线性嵌段聚醚氨基硅油的合成工艺,以双端氨基聚醚与双端环氧基聚醚硅油为反应单体,异丙醇为溶剂,通过开环聚合一步反应制备线性嵌段聚醚氨基硅油(LEPS),并将其应用于羊绒针织物的柔软整理。借助傅里叶变换红外光谱仪、热重分析仪、多功能表面分析电子能谱仪与扫描电子显微镜等表征LEPS及其整理织物的理化性能。结果表明:当2种反应单体的量比为1:1,所得LEPS氨值为0.14 mmol/g、摩尔质量为 7.39×10 ⁴ g/mol,其乳液的稳定性能优良;LEPS整理织物手感达到5级,柔软、蓬松性能突出,并且织物的亲水、透湿与抗静电性能良好,黄变程度低;LEPS的综合性能优良,制备工艺简单。

Preparation and properties of linear polyether-blocked amino silicone

In order to simplify the synthesis process of linear polyether-blocked amino silicone oil, the linear polyether-blocked amino silicone oil (LEPS) was prepared by ring opening polymerization using diterminal aminoether and diterminal epoxy polyether silicone as monomers and isopropyl alcohol as a solvent, and the LEPS was applied to the soft finishing of knitted cashmere fabric. The physicochemical properties of LEPS and fabrics finished with LEPS were characterized by means of Fourier transform infrared spectrometer, thermogravimetric analysis, multi-functional surface analysis electron spectrometer and scanning electron microscopy. The results show that when the mole ratio of two monomers is 1:1, the ammonia value of LEPS is 0.14 mmol/g, and the molar mass is 7.39×10 ⁴ g/mol, and the emulsion has excellent stability. The fabric finished with LEPS has outstanding soft and fluffy properties, hand feeling to grade 5 and good hydrophilicity, moisture permeability and static resistance as well as low degree of yellowing. LEPS has the advantages of excellent comprehensive properties and simple preparation process.
