| 摘 要： | 采用溶胶-凝胶法,以甲基三甲氧基硅烷为前驱体,氨水为催化剂,十六烷基三甲氧基硅烷为拒水添加剂,在表面活性剂十二烷基苯磺酸钠作用下,添加硅烷偶联剂,制备了改性纳米SiO2水溶胶,并将其用于棉织物的耐久疏水整理;探讨了硅烷偶联剂种类及添加量对棉织物耐洗性的影响.结果表明,用添加2％正硅酸四乙酯(TEOS)制得改性SiO2水溶胶,整理后棉织物具有耐久的拒水效果,皂洗20次后,棉织物的接触角和滚动角分别可达141.5°和25.0°,沾水评级75分.

| Abstract: | Modified silica hydrosol is prepared by water-based sol-gel method using methyltrimethoxysilane(MTMOS) as the precursor,ammonia as the catalyst and hexadecyltrimethoxysilane(HDTMS) as the hydrophobic additive,and tetraethyl orthosilicate(TEOS) is added in the presence of the anionic surfactant of sodium dodecyl benzenesulfonate(SDBS).Superhydrophobic finish of cotton fabric is carried out with the modified silica hydrosol.The effects of the type of silane coupling agent and the adding dosage on durability a... |
