摘　　要：本文采用SiC粉、聚二甲基硅氧烷(PDMS)、固化剂为原料制备浆料,研究了SiC含量对浆料黏度、流动性和悬浮稳定性的影响规律;采用气动式墨水直写打印设备,探索SiC含量、挤出压力和喷嘴直径对浆料挤出性能的影响规律。结果表明,随着SiC含量的增加,浆料的黏度逐渐增加、流动性逐渐降低。不同SiC含量的浆料在实验范围内均具有较好的沉降稳定性。增大喷嘴直径以及提高挤出压力均使得浆料挤出量增加。当喷嘴直径为0.33mm时,浆料能够稳定挤出。In this paper,SiC particles,polydimethylsiloxane(PDMS)and curing agent were used as raw materials to prepare slurry.The effects of SiC content on viscosity,fluidity and suspension stability of slurry were studied.The effects of SiC content,pneumatic pressure and nozzle diameter on the stability of slurry extrusion were studied by pneumatic direct ink writing printer.The results show that the viscosity of the slurry increases and the fluidity of the slurry decreases with the increase of SiC content.The slurry with different SiC contents have good settling stability in the experimental range.Increasing the nozzle diameter and extrusion pressure can increase the amount of slurry extrusion.When the nozzle diameter is 0.33 mm,the slurry can be extruded stably.
