| 摘 要： | 选用分散剂甲基纤维素（Methyl cellulose,MC）,通过球磨分散法制备铟锡氧化物（Indium tin oxide,ITO）水相浆料;研究MC用量、ITO粉体用量和球磨分散时间对ITO浆料稳定性能的影响及MC的分散机理。研究结果表明：MC在球磨分散ITO浆料过程中起到很好的分散作用,它的分散机制为静电位阻稳定作用;当MC相对ITO粉体质量分数恒定时,随着MC用量、ITO粉体用量和球磨分散时间的增加,ITO浆料稳定性增强。当MC用量相对ITO粉体质量分数为15.0%,球磨分散时间为48 h时,ITO浆料稳定性最强,浆料在120 d内浆料分散稳定性指标R均小于1.8%。

| Abstract: | Indium tin oxide(ITO) aqueous suspension was prepared through ball milling dispersion using Methyl cellulose(MC) as dispersant.The effects of MC dosages,ITO content and ball milling dispersion time on stability of ITO aqueous suspension were investigated.And the functional mechanism of MC for dispersing ITO suspension was also discussed.The results show that MC is a good dispersant for preparation of stable ITO aqueous suspension through ball milling dispersion,and its mechanisms of stability and dispersion are electrostatic and steric hindrance.When the mass ratio of MC and ITO is a constant,the stability of ITO suspension enhances with the increase of MC dosages,ITO content and ball milling dispersion time.And ITO aqueous suspension possesses the best stability and R<1.8% within 120 d when mass ratio of MC to ITO is 15.0% and ball milling dispersion time is 48 h. |
