摘　　要：以纳米颜料(P.R颜料红122)色浆为基础,分别添加1,2–戊二醇、1,2–丙二醇、二甘醇和乙二醇及多种表面活性剂配制成打印墨水分散体系,研究各种助剂对分散体系粒径、黏度、保湿性和表面张力的影响.结果表明,助剂的种类和用量对纳米颜料喷印墨水的稳定性及其他性能影响很大.各种多元醇中,1,2–戊二醇对分散体系粒径和稳定性影响最大,过量使用可导致体系的贮存稳定性显著降低;体系的黏度及保湿性均随1,2–戊二醇、1,2–丙二醇、二甘醇和乙二醇用量增加而提高;表面活性剂可降低分散体系的表面张力,但改性效率随品种而变.研究所得纳米颜料喷印墨水可满足实际应用.Spraying print ink dispersion was prepared by adding 1,2-pentanediol, 1,2-propanediol, diethylene glycol and ethylene glycol into nano pigment （P.R.pigment magenta 122）paste. The influence of additives on the pigment particle size, viscosity, moisture retention and surface tension of the dispersion was investigated. The results show that the stability of the nanometer pigment spraying print ink depend strongly on the types and contents of additives. 1,2- pentanediol is most influential to the particle size and stability of the dispersion system,overcommitting of it can significantly decrease the storage stability. The viscosity and moisture retention of the dispersion were increased with the dosage of 1,2-pentadiol, 1,2-propanediol,diethylene glycol and ethylene glycol. Surface tension of the dispersion could be reduced by surfactants. But the efficiency in modification changes with the type of surfactants. Nano pigment spraying print ink made can meet the application requirements.
