摘　　要：利用一种新型的分散剂—梳型共聚物poly(acrylic acid)-poly(ethylene oxide)(PAA-PEO),研究了pH、分散剂的添加量及固含量对ZrO2-H2O悬浮液的流变性能的影响。结果表明:在pH为3、PAA-PEO的添加量为0.3wt%,ZrO2-H2O悬浮液的粘度最低;固含量在31vol%以下时,浆料都保持稳定状态;随着固含量的增加,浆料的粘度也增加,当固含量达到33vol%时,浆料呈现出明显的剪切变稀行为。The influence of pH, concentration of the dispersant and solids loading to rheological properties of aqueous ZrO2 suspensions were studied by using a new dispersant poly（acrylic acid）-poly（ethylene oxide） （PAA-PEO） comb polymer. The results are clearly shown that： when pH is 3 and concentration of PAA-PEO is 0.3wt%, the viscosity of the aqueous ZrO2 suspensions is in much low; When the solids loading are below 31vol%, all aqueous ZrO2 suspension is steady; the viscosity of aqueous ZrO2 suspension increases with increasing of the solids loading, the suspension show behavior of shear thinning when the solids loading arrived 33vol%.
