中文摘要:

      研究了有机膨润土对彩色喷墨打印纸（简称彩喷纸）涂料黏弹性的影响。结果表明，含有机膨润土的彩喷纸涂料表现为剪切变稀的假塑性流体特征，有机膨润土能够提高彩喷纸涂料的黏度，增稠效果明显；含有机膨润土的彩喷纸涂料表现出较强的弹性固体特征。在同一扫描频率下，含有机膨润土涂料的弹性模量和黏性模量高于不含有机膨润土的涂料。

Abstract:

      The effect of organic bentonite on the viscoelasticity of paper coatings was studied．The results showed that the paper coatings containing organic bentonite characterized as pseudoplastic fluid with obvious shear thinning behavior．The viscosity of paper coatings increased obviously with increasing the amount of organic bentonite. The paper coatings containing organic bentonite showed the property of strong viscoelastic solid．In the same scanning frequency，both elastic modulus and viscous modulus of the paper coatings containing organic bentonite were higher than that of the paper coatings without organic bentonite．
