中文摘要:

      目的 研究铝银浆的种类、研磨树脂的对应颜基比及分散剂配比对水性银墨基墨粒径的影响。 方法 以铝银浆为油墨颜料，与研磨树脂、分散剂、去离子水及助剂均匀混合搅拌，制备成水性银墨基墨，通过激光粒度仪测试基墨粒径。结果 使用DZR05号铝银浆，AZR研磨树脂，颜基比（质量比）为2∶3，760与3200分散剂的质量比为2∶3，分散剂的质量分数为5%时，制备的水性银墨基墨粒径最小。结论 性能良好的铝银浆，合适的研磨树脂及对应颜基比，适宜的分散剂配比及质量分数，有利于降低水性银墨基墨的粒径。

英文摘要:

      The work aims to study the effects of the types of aluminum silver paste, the corresponding binder ratio of grinding resin, dispersant ratio and mass fraction of dispersants on the particle size of water-based silver ink paste. The water-based silver ink paste was prepared by mixing aluminum silver paste with grinding resin, dispersant, deionized water and auxiliary agent. The particle size of the ink paste was tested by laser particle size analyzer. The particle size of water-based silver ink paste prepared with DZR05 aluminum silver paste and AZR grinding resin was the smallest when the binder ratio was 2∶3, the ratio of 760 dispersant to 3200 dispersant was 2∶3 and the mass fraction of dispersant was 5%. The particle size of water-based silver ink paste can be reduced by aluminum silver paste with good properties, suitable grinding resin and its corresponding binder ratio, suitable dispersant ratio and mass fraction.
