摘要
利用环氧基聚醚封端的聚二甲基硅氧烷(α,ω-PESO)与N,N-二甲基丙二胺的开环加成反应,合成了一种线型聚醚氨基硅(LPEAS)。采用红外光谱(IR)、核磁共振氢谱(1HNMR)、透射电子显微镜(TEM)、纳米粒度仪等仪器对线型聚醚氨基硅及其乳液进行了表征分析,并探讨了氨值、黏度、硅乳用量对棉织物应用性能的影响。结果表明,聚醚氨基硅乳液平均粒径仅为27 nm,经氨值为0.4 mmol/g、黏度为0.950 Pa.s、硅乳用量为10 kg/t的LPEAS整理的布样,100℃烘5 m in再160℃定型30 s时,织物弯曲刚度明显下降,吸水性增强,白度基本不变。
A new linear-chain polyether-aminosiloxane（LPEAS） was synthesized by the reaction of epoxy polyether terminated polydimethylsiloxane with N,N-dimethyl-propanediamine.The Chemical structure of LPEAS was characterized by IR and 1HNMR.Then the particle sizes,particle sizes distribution were investigated by transmission electron microscope（TEM） and other instruments.The effects of its viscosity,amino value and the amount of the emulsion on the performance of treatment of cotton fabrics were also studied.The results showed that average particle size of LPEAS emulsion was only 27 nm,cotton fabric featured hydrophilicity improved,the bending rigidity of fabric decreased,and the whiteness of the fabrics remained the same,when the viscosity of LPEAS was 0.950 Pa·s,amino value was 0.4 mmol/g,the amount of the emulsion was 10 kg/t,and curing at 100 ℃ for 5 min following 160 ℃ for 30 seconds.
