摘要
对纳米ZrO2和纳米TiO2的复合粉体的水基悬浮液的分散性能及在皮革上的应用情况进行了研究。用超声波细胞粉碎机来分散粉体悬浮液,并用吸光度来表征其分散效果,结果表明比例不同,复合粉体的最大吸收波长和最佳分散条件各不相同;相同质量浓度的复合粉体悬浮液处理皮革后,用温升和降温性能表征皮革的保暖性,结果表明,比例不同,处理后蓝湿革的保暖性能不同,其中m(ZrO2)∶m(TiO2)为2∶1(质量比)时处理的蓝湿革的保暖性能最好。
The compound powders of nano ZrO2 and TiO2 aqueous suspension, and application ot them to leather were studied. Dispersion degree of these powders suspension dispersed with a ultrasonic cell disrupter system was expressed by absorbency, the result showed that the maximum absorbency wavelength（λm for short） and the optimal dispersing condition were different according to the ratio ; Warm keeping performance of leather dealt with these powders＇ suspension, was measured by temperature rising and declining, the result showed that the warm keeping performance was also different by the ratio , and when ZrO2 and TiO2 was at the weight ratio of 2 ： 1, the warm keeping performance was best.
