摘　　要：采用溶胶-凝胶法、以钛酸丁酯为前驱体、水为溶剂、冰醋酸为稳定剂和催化剂,制备了纳米二氧化钛水溶胶。研究了滴加顺序、水和冰醋酸用量等因素对水溶胶稳定性和紫外线-可见光吸收性能的影响。实验结果表明,当钛酸丁酯、冰醋酸和水的量比为1∶8∶60时制得的溶胶性能较好。将该水溶胶用于棉织物的整理,先将棉织物在溶胶中浸渍30min后浸轧,100℃烘干5min,150℃焙烘5min,120℃汽蒸60min,可获得良好的抗紫外性能和自清洁性能。Nano-TiO2 hydrosol was prepared by sol-gel method with tetra-butyl ortho-titanate as precursor,water as solvent and acetic acid as the stabilizing agent and catalyst.The influences of the adding order,the dosage of the water and acetic acid on the stability and UV-visible absorption properties of TiO2 hydrosol were studied.When the molar ratio of tetra-butyl ortho-titanate,acetic acid and water equals was 1∶8∶60,the best performance of sol could be obtained.Dipping the cotton fabric in the sol of 30 min,pad finishing,100 ℃ drying 5 min,150 ℃ baking 5 min and 120 ℃ steaming 60 min,good performance of anti-UV and self-cleaning could be obtained.
