Application Performance of Lignin-Modified Amino-Sulfonic Acid-Based Dispersant on the Ceramic Slurry

Abstract:

Lignin-modified amino-sulfonic acid-based dispersant LMA was synthesized by using soda lignin to substitute part of phenol. Effect of LMA on ceramic slurry performance was studied and compared with inorganic salt dispersant. The addition of LMA endows ceramic slurry with lower viscosity, better fluidity and stability. Particle size of ceramic slurry blended with LMA is clearly decreased and grinding efficiency improves. LMA can enhance particle electro-negativity by complexing high valence cations and polymeric anion-adsorbing on ceramic particles surface by hydrogen bonds. The dispersive effect of LMA to ceramic particles is the combined action of steric effect and electrostatic repulsion.
