摘要
采用混酸法制备纤维素纳米球,并以其为分散剂,通过与其他助剂混合制得性能优良、分散稳定的数码印花墨水。扫描电镜显示,混酸法制备的纤维素纳米球的粒径在50 nm左右,Zeta电位仪测定其具有较高的电负性。将其与活性墨水及其他助剂混合,正交试验结果表明,纤维素纳米球对墨水的黏度及电导率起到重要的影响作用。将其与商用墨水进行对比,可以发现自主配制的数码印花墨水在黏度、电导率及Zeta点位等性能指标上均优于普通商用墨水。
The cellulose nanoparticles were prepared by mixed acid method,and they were used as the dispersant to prepare the digital printing ink with good properties and dispersion stability by mixing with other additives.Scanning electron microscope result showed that the particle size of the cellulose nanoparticles prepared by the mixed acid method was about 50 nm,and the cellulose nanoparticles had high electronegativity according to Zeta potentiometer test.After the cellulose nanoparticles were mixed with other additives,the orthogonal testing results showed that the cellulose nanoparticles played an important role for the viscosity and conductivity of the inks.Compared with the commercial inks,the inks prepared in this study have the good properties such as the viscosity,conductivity and Zeta potential.
