摘　　要：为了研制性能优良的水性喷印墨水,采用直接蓝199为着色剂,添加甘油、乙醇和乙二醇等有机溶剂调节墨水的黏度和干燥速度,用非离子型表面活性剂调节墨水的表面张力。用紫外分光光度计测试墨水的吸光度,发现当染料用量达到一定量时,吸光度不再变化。表面活性剂用量小于0.1%(质量分数)时,表面张力急剧降低。用离心机测试墨水的稳定性,结果表明,研制出的墨水高速旋转后比吸光度高,稳定性好。Water-based ink jet ink with excellent performance was prepared. Direct blue 199 was used as colorant; glycerin,alcohol, and glycol was used to adjust the viscosity and drying rate; and a nonionic surfactant was used to adjust the surface tension of ink. UV absorption spectrophotometer results showed that when the dye concentration reaches a certain amount,no change in absorbance. Surface tension reduces sharply with surfactant concentration increasing to 0.1 percent. The ink stability was tested with centrifuges. The results showed the ink stability is good with high absorbency ratio.
