摘要
本文先通过D4、MM、D3F和氨基硅烷等的本体聚合反应制备含氨基及三氟丙基的系列聚硅氧烷(FRASO),然后在催化剂作用下,使聚硅氧烷侧链氨基与马来酸酐作用,将羧基引入聚硅氧烷侧链制得新型羧基改性聚硅氧烷(FRCAS)。用非离子表面活性剂T-99对FRASO及FRCAS进行乳化,并分别将其用于织物整理中。用红外光谱仪(FT-IR)、核磁共振仪1H-NMR、Zeta电位仪等仪器对产物结构及乳液物化性能进行表征和测试。结果表明:FRASO、FRCAS与预先设计的分子结构一致。FRCAS乳液平均粒径为101.5 nm,粒径分布窄。Zeta电位为-43.6 mV,乳液稳定性强。织物经整理后,柔软度和白度均有所提高,具有一定的疏水性,FRCAS处理过的织物疏水性明显低于FRASO处理过的织物。
In this paper,a series of polysiloxanes(FRASO)containing amino group and trifluoropyl group were prepared by bulk polymerization of D4,MM,D3F and aminosilane,and then a new type of carboxyl modified polysiloxane(FRCAS)was prepared by introducing carboxyl group into the side chain of polysiloxane under the action of catalyst.FRASO and FRCAS were emulsified with nonionic surfactant T-99 and used in fabric finishing respectively.The structure and physicochemical properties of the emulsion were characterized by infrared spectroscopy(FT-IR),nuclear magnetic resonance(1H-NMR)and Zeta potentiometer.The results showed that the molecular structures of FRASO and FRCAS were consistent with the pre-designed molecular structures.The average size of FRCAS emulsion was 101.5 nm and the particle size distribution was narrow.The Zeta potential was-43.6 mV,and the emulsion stability was strong.After finishing,the softness and whiteness of the fabric were improved,and the hydrophobicity of FRCAS treated fabric was obviously lower than that of FRASO treated fabric.
