Abstract

Styrene, methyl methacrylate (MMA) and trimethyl (methyl acryl acyl oxygen) ethyl ammonium chloride were randomly copolymerized to prepare a cationic macromolecular dispersant (SMD) applied in cationic pigment dispersions. The influence of the dispersant concentration on the particle size and centrifugal stability of the pigment dispersions was also studied. The pigment particle size could be as small as 225 nm (Z average) and the centrifugal stability could also be improved, when the dispersant was 1.25 percent the specific absorbency was 97.3%. The influence of the diethylene glycol (DG) dosage on the particle size and stability was also investigated, as the result, the particle size and centrifugal stability was perfect when the DG dosage was 28.2%. Compared with NNO and Tween80, SMD is able to pretend the reassembling of pigment particle more effectively and have better dispersing result.
