摘　　要：利用分散法制备铁红色陶瓷釉料墨水。研究分散剂中十六烷基三甲基溴化铵、羧甲基纤维素钠、聚乙二醇400的不同含量对釉料墨水的粘度和电导率的影响,并测定釉料墨水的流变、表面张力及稳定性。结果表明:制备性能优良的釉料墨水,分散剂中CTAB、羧甲基纤维素钠、聚乙二醇400的含量分别为40wt%、45wt%、15wt%;釉料墨水具有一定的触变性,并具有非牛顿性流体的性质,粘度为40 m Pa·s;表面张力随着时间的延长而减小,最终趋向一定值,大小为38.2 m N/m;随着时间的延长,釉料墨水底部沉淀减少,中部稳定性较好,上部的澄清区增加。Iron red ceramic glaze ink was prepared by dispersion method. It was investigated that different contents of cetyhrimethyl ammonium bromide （CTAB）, sodium carboxymethyl cellulose and polyethylene glycol 400 influenced on viscosity and conductivity of glaze ink. The properties were measured such as rheological property, surface tension and stability. The glaze ink with excellent properties is produced when the contents of CTAB, sodium carboxymethyl cellulose and polyethylene glycol 400 in the dispersant are respectively 40wt% , 45wt% , and 15wt%. The prepared glaze ink exhibits certain thixotropy and the nature of non Newtonian fluid. Viscosity of glaze ink is 40 mPa · s. Surface tension decreases over time and eventually approach to a certain value of 38.2 mN/m. With the extension of time, the precipitation reduces at the bottom of glaze ink, stability in the middle is better and clarification zone on the top increases.
