摘　　要：采用八甲基环四硅氧烷与四甲基二氢基二硅氧烷在浓硫酸作用下合成含氢硅油,然后以氯铂酸为催化剂,烯丙基缩水甘油醚与含氢硅油发生硅氢加成合成环氧改性有机硅,最后通过二乙醇胺对环氧改性有机硅进行开环反应得到氨基有机硅。采用FTIR和1HNMR对产物结构进行表征,研究氨基有机硅的润湿性能,测定得到其临界胶束浓度为0.102 g·L-1,并与嵌段硅油9906和共聚改性嵌段硅油进行比较研究。结果表明,润湿力随氨基有机硅含量的增加而增强,相同含量下,氨基有机硅的氨值越大,其对帆布的润湿力越强,所合成氨基有机硅微乳液的稳定性、整理后织物的亲水性和柔软手感均比嵌段硅油9906和共聚改性嵌段硅油好。Hydrogen containing silicone fluid was synthesized by using octamethylcyclotetrasiloxane and 1,1,3,3- tetramethyldisiloxane as starting materials under the action of concentrated sulfuric acid. Then hydrosilylation between allyl glycidyl ether and the hydrogen containing silicone fluid was carried out with chloroplatinic acid as catalyst to produce epoxy modified silicone. Finally, ring opening reaction of the epoxy modified silicone was processed with diethanolamine to obtain amino silicone surfactant as the product. Structure of the product was characterized by FTIR and I HNMR. Wetting power of the amino silicone product was investigated, and its cmc was determined as 0. 102 g · L-1. Performance of the product was compared with that of block silicone oil 9906 and co - modified block silicone oil. Results showed that wetting power increases with the increase of content of amino silicone. Under the same content of amino silicone, the higher ammonia value of the amino silicone, the stronger wetting power to canvas sample. All the performance in application of the amino silicone surfaetant such as stability of microemulsion prepared by amino silicone, hydrophilicity and hand feeling softness of cotton fabrics finished with amino silicone are better than that of block silicone oil 9906 and co- modified block silicone oil.
