摘　　要：水性喷墨打印技术是目前构筑瓷砖表面釉层的新型方式,所使用的水性陶瓷浆料的稳定性对其喷墨打印性能起到了至关重要的作用。以市购的陶瓷喷墨原浆为原料,采用分散法制备了系列瓷砖表面喷墨打印改性陶瓷喷墨浆料,重点考察了分散剂种类、含量等因素对陶瓷喷墨浆料长期悬浮稳定性、粘度、表面张力的影响规律,结果表明:相比于陶瓷喷墨原浆,添加3 wt%PAAS的陶瓷喷墨浆料具有良好的粘度(52.42 mPa.s)和表面张力(68.3m N/m),满足喷墨打印使用要求。而且,PAAS改性浆料在30天静置沉降过程中未出现硬质沉淀的不良特征,表现出更高的悬浮稳定性,这归因于分散剂PAAS与原浆表面形成双层电荷,同时依靠长分子链,起到静电位阻稳定作用。研究的相关结果对于开发新型的瓷砖表面用的高稳定性陶瓷喷墨浆料具有指导意义。Water-borne ink-jet printing technology is an innovative method to fabricate a glaze layer on the surface of ceramic tiles,and the stability of the water-borne ceramic ink slurry is a key factor in deciding its printing performance.A series of modified ceramic ink slurry for inkjet printing of ceramic tiles was prepared by the dispersion method using unmodified ceramic ink slurry purchased from the market.The effects of type,content and other factors of dispersants on the long-term suspension stability,viscosity and surface tension of ceramic ink slurry were studied.The results show that compared with the unmodified ceramic ink slurry,the ceramic ink slurry with addition of 3 wt%PAAS has good viscosity(52.42 mPa·s)and surface tension(68.3 mN/m),which can meet the requirements of inkjet printing.In addition,the PAAS modified slurry showed no adverse characteristics of hard precipitation in the 30-day static settlement process and showed higher suspension stability,which was attributed to the formation of double charge between the dispersant PAAS and the plasma surface and the stability of electrostatic steric hindrance by relying on long molecular chains.The relevant results of this study have guiding significance for the development of a novel ceramic ink slurry with high stability for ceramic tile surfaces.
