摘　　要：通过使用不同结构的分散剂分散表面性质各异的炭黑，考察了炭黑的表面性质、分散剂的结构、体系ｐＨ 值及电解质的加入对水性体系中炭黑分散的影响。研究发现以疏水端为平面分子、亲水端为可解离盐基的离子型聚合物分散剂来分散原生粒子较小的酸性炭黑时。Effects of surface property of carbon black,structure of dispersant,pH value of system and addition of electrolyte on the dispersion of carbon black in waterborne system are investigated.It was found that when carbon black with small primal particle size is dispersed with ionized polymer dispersant in which plane molecular seroes as hydrophobic group and salt group serves as hydrophilic group, a good dispersion can be abtained.
