摘　　要：超细颜料墨水的喷射性能与墨水的组成密切相关。采用超细颜料、模拟多元醇和表面活性剂等组成超细颜料水性分散体系,观察了不同配方配制的超细颜料分散体系的喷射性能。通过测试分散体系粘度、表面张力等理化指标在分散机高速剪切和超声波处理后的变化情况,分析了超细颜料水性分散体系喷射性能与体系粘度和表面张力的关系。结果表明,超细颜料水性分散体系的粘度、表面张力以及超声波处理后粘度的变化决定着体系的喷射性能。The ink-jetting property of pigment inks is closely related to the ink formulation. A simulative pigment ink was prepared with water-based ultrafine pigment dispersions, polyols, surfactants and additives. The ink-jetting property was observed with a set of ink-jetting equipment. The relationship between the ink-jetting property and the viscosity and surface tension of the simulative pigment ink was investigated. The result shows that the ink-jetting property is determined by the viscosity and surface tension of pigment ink. The variation of viscosity after ultrasonic treatment could reflect the ink-jetting property.
