摘　　要：在水性涂料中的颜料的分散受到包含在分散浆中的共存有机溶剂的分散性的影响，在水系统中颜料分散稳定性主要受到疏水性相互作用的影响。把共存有机溶剂的影响作为参数，测定了在有机溶剂共存下的[水／己烷]间的表面张力数值γbsw，研究了它与分散性的关系。In water-borne paints, the dispersion of pigment is influenced by the dispersive Characteristics of co-solvent in dispersion liqued. And in the water-borne system, the stability of pigment dispersion is mainly influenced by the mutual affection of hydrophobic properties. Take the influence of co-solvent as paramester, test the surface tension value γbsw, of [water/hexane] under the organic solvent coexisted condition, and study the relation with its. Dispersive ability.
