Dispersion Properties of Zeolite Pigment Used in Ink Jet Paper

Zeolite pigment was used to replace the traditional pigment silica used in ink-jet paper, and the influence of dispersant kinds and dosage, rotating speed of disperser, dispersing time and dispersion liquor concentration on the dispersion properties of zeolite pigment were discussed by using single factor control variable method. The dispersion properties were characterized by testing the average particle size and the viscosity of the zeolite dispersion liquor. The experimental results showed that DMDAAC is the best dispersant and the optimal dispersion conditions are the dosage 3%, the dispersion liquor concentration 50%, the rotating speed of disperser 5000 r·min -1 , the dispersing time 60 min.
