离子液体bmimBF4的合成及其对涤纶织物抗静电性能的影响

摘要

研究了离子液体[bmim]BF4的合成，采用IR、1HNMR进行结构表征；分析了离子液体用量、轧余率、焙烘温度对涤纶织物抗静电性能的影响。结果表明：成功合成离子液体[bmim]BF4；[bmim]BF4用量25 g/L、轧余率80%、焙烘温度170℃时，整理的涤纶织物具有较好的抗静电性能，但耐洗性较差。通过TiO2/SiO2水溶胶进行后处理可以提高其耐洗性。%The synthesis of ionic liquids [bmim]BF4 was investigated and the structure of product was characterized by IR and 1HNMR. The effects of the dosage of ionic liquids [bmim]BF4, wet pickup and the cur-ing temperature on the antistatic property of polyester fabric were discussed. The results showed that the ion-ic liquids [bmim]BF4 was successful y synthesized. The finished polyester fabric had good antistatic properties when the dosage of [bmim]BF4 was 25 g/L, wet pickup was 80% and the curing temperature was 170 ℃, however, the durability was poor. The durability could be improved by the treatment of TiO2/SiO2 hydrosol.
