纳米氧化铝锌在棉织物隔热整理中的应用
|
摘要
通过共沉淀法合成了具有隔热效果的纳米氧化铝锌(AZO),并采用浸轧法整理到棉织物表面,对AZO的分散性能和整理棉织物的隔热性能进行了探讨。结果发现,经过球磨后纳米AZO分散液的平均粒径可以达到282 nm,具有优良的分散性能。采用3%的纳米AZO整理液对棉织物进行整理,能够使自制隔热装置温度降低4.3℃,并且织物对紫外-可见-近红外区域具有较强的光屏蔽性能。
The aluminium doped ZnO(AZO) nano pigments with thermal insulation effect were synthesized by coprecipitation method, and finished onto the fabric by padding process. The dispersibility of AZO and thermal insulation property of finished cotton fabric were investigated. The results showed that the average particle size of nano AZO dispersion could reach 282 nm after ball milling, indicating that it had excellent dispersibility. The cotton was finished by 3% AZO, which could decreased the temperature of self-made heat insulation device by 4.3 ℃. And the finished fabric could effectively block the UV/visible/near-infrared radiations.
