摘　　要：以带有活性基团的碘丁基硅油(IBu-PDMS)与氨基磺酸胍为原料,制备具有拒水阻燃双功能的碘丁基-N-磺酸氨基聚硅氧烷(IB-N-SA)PDMS。测定了(IB-N-SA)PDMS整理棉织物的接触角和拒水等级;通过氧指数、热重分析和棉织物燃烧后残炭的形貌,分析了其阻燃性能、热性能及阻燃机理。(IB-N-SA)PDMS可赋予棉织物拒水性能,接触角由88.37°提高到110.75°,拒水分值为90;整理棉织物燃烧后的残炭率由11.7%提高到33.6%,说明阻燃剂通过改变棉纤维的热裂解过程,促进了纤维的脱水炭化;整理棉织物的极限氧指数由18.0%提高至29.4%。Water repellent and flame retardant agent iodine butyl-N-sulfonate amino polysiloxane [（IB-NSA）PDMS] is synthesized using poly（4-iodobutoxy） methylsiloxane and guanidine sulfamate as raw materials. The contact angle and water repellency of treated cotton fabric with [（IB-N-SA） PDMS] are tested. The thermal property, flame retardancy and its mechanism are investigated by oxygen index analyzer and TG. The results show that（IB-N-SA） PDMS can impart cotton fabric good water repellent properties with 90 grade of water repellency, and the contact angle increases from 88.37° to 110.75°. Carbon residue of burned fabric increases from 11.7% to 33.6%, which indicates that the flame retardant agent can promote dehydration carbonization of fiber by changing cotton fiber pyrolysis. Limit oxygen index of cotton fabric increases from 18.0% to 29.4%.
