水性分散剂阳离子型：是非极性基带正电荷的化合物。品种有十八碳烯胺醋酸盐。烷基季铵盐、氨基丙胺二油酸酯、季胺盐、特殊改性的多氨基酰胺磷酸盐等。阳离子表面活性剂吸附力强，对炭黑、各种氧化铁、有机颜料类分散效果较好，但要注意其与基料中羧基起化学反应，还要注意不要与阴离子分散剂同时用，使用应慎重。
Water dispersing agent cation type: it is a compound with non-polar base band positive charge. The variety is octadecylamine acetate. Alkyl quaternary ammonium salt, aminopropylamine dioleate, quaternary amine salt, specially modified polyamine phosphate, etc. The cationic surfactant has strong adsorption and good dispersing effect on carbon black, various iron oxides and organic pigments, but it should be noted that it reacts with carboxyl group in the base material, and it should not be used at the same time with anionic dispersant.
