含附固功能水性有机硅织物柔软剂的研制

Preparation of water soluble fast adhesive organosilicone fabric softener

采用硅烷偶联剂γ-氨丙基三乙氧基硅烷(APTES)及甲苯二异氰酸酯(TDI)等作为204水溶性有机硅油(Si-204)改性材料,研究了相关的接枝反应改性方法。选择在70℃~75℃下反应3.5h^4.0h,得到了一系列含反应活性的有机硅半透明液、微乳液和乳液型水性有机硅织物柔软剂,并对其性能作了测试,采用红外光谱对有关产物和乳液进行了结构分析。结果表明:水性有机硅作为织物柔软剂对织物纤维附着率随反应活性功能基含量的增加从0提高到60%以上。

The method for graft modification reaction of water soluble organosilicone （ Si-204 ） withγ -aminopropyltriethoxysilane（APTES）and toluene diisocyanate as modifying agents was studied. The reaction was carried out at 70 ℃ - 75 ℃ for 3.5 h - 4.0 h. A series of water soluble organosilicone fabric softener product with fast adhesive activity in emulsion form and microemulsion form were prepared. The performance of the product was tested and the structure was studied by IR spectrum. The results show that, the adhesiveness of the fabric softener can be increased for 60 %.
