摘要：以环氧硅油、氨丙基三乙氧基硅烷(KH550)和3-缩水甘油醚氧丙基三甲氧基硅烷(KH560)为原料,以二丁基二月桂酸锡为催化剂,通过溶胶-凝胶法制备了支链有机硅改性硅溶胶型拒水剂,并将其应用于棉织物。通过测试分析傅里叶红外光谱、热失重、粒径、接触角和吸水率,对拒水剂的结构和拒水性能进行表征;考察了拒水剂用量、焙烘温度对织物拒水性能的影响,得出优化的整理条件为:拒水剂0.8%、焙烘温度120℃。整理后织物与水的接触角可达133.8°,表明支链有机硅改性的硅溶胶具有良好的拒水效果。
The branched silicone-modified silica sol water repellent is prepared by sol-gel method with KH-550, KH-560 and ep- oxy-modified polysiloxane as raw materials and dibutyl tin dilaurate as catalyst, and is applied to cotton fabric. The structure and performance of water repellent are characterized by FT-IR, TGA, particle size, contact angle and water absorption. Influences of agent dosage and curing temperature on water repellency are discussed. The finishing conditions are optimized as 0. 8% of water repellent and curing temperature 120°;. The contact angle of finished fabric can reach 133.8°.
