侧链型聚醚改性氨基硅的合成及应用

Synthesis and Application of Side-chain Polyether-containing Aminopolysiloxane

摘要:

制备了一系列黏度0.150~1.800 Pa•s，氨值0.200~0.596mmol/g，折光率nd201.6567~1.6685，水溶性良好的亮黄色透明液体，聚醚改性氨基硅（SPEAS）。合成较佳工艺条件为:反应温度60~100℃,反应时间4~8 h。采用FTIR,1H-NMR和TEM对有关产物和乳液进行了结构分析,结果表明，质量分数为2.0%的SPEAS水溶液粒径大小有差别。经其整理的棉布弯曲刚度减小(柔软性增强)、折皱回复角增大, 静态吸水时间降至1″48。

Abstract:

The water-soluble Polyether-containing Aminopolysiloxane (SPEAS)was synthesized, the viscosity, amino value and nd20 of which were 0.150~1.800 Pa•s, 0.200~0.596mmol/g and 1.6567~1.6685.The optimum conditions were 60~100℃(reaction temperature), 4~8 h (reaction time). Then the structures and properties of the samples were analyzed by FTIR,1H- NMR and TEM. Experimental results showed that the size of the particles of such aqueous dispersions at 2.0% are different. The bending rigidity of the treated fabric decreased (the soft hand-feeling enhanced), its wrinkle ecovery angle increased and static water absorption time downed to 1″48.
