Low-temperature sintering high-toughness ceramic powder slurry for 3D printing process
The invention discloses a low-temperature sintering high-toughness ceramic powder slurry for a 3D printing process. The formula of the low-temperature sintered high-toughness ceramic powder slurry forthe 3D printing process comprises the following components in parts by weight: 100-180 parts of aluminum oxide, 50-120 parts of potassium hexatitanate, 500-800 parts of whisker silicon, 150-350 partsof lithium feldspar, 120-240 parts of serpentine, 80-120 parts of neutral aluminum sol, 2-6 parts of thixotropic agent, 8-14 parts of dispersing agent, 15-37 parts of thickener, 3-11 parts of leveling agent and 200-480 parts of water. In the invention, lithium feldspar is added into the formula of the ceramic powder slurry for the 3D printing process, wherein the lithium feldspar powder can be used as a cosolvent for aluminum oxide, serpentine and whisker silicon as a large amount of alkaline substances, and the melting temperature of the ceramic powder slurry for the 3D printing process is reduced due to the low melting temperature of the lithium feldspar, so that the melting temperature of the ceramic powder slurry for the 3D printing process is reduced; therefore, the sintering temperature range of the alkaline cooling mineralizer is widened, so that the ceramic powder slurry for the 3D printing process can be used for 3D printing in a low-temperature sintering manner.
本发明公开了一种低温烧结高韧性3D打印工艺陶瓷粉体浆料，按质量份数计，该低温烧结高韧性3D打印工艺陶瓷粉体浆料的配方包括：氧化铝100‑180份、六钛酸钾50‑120份、晶须硅500‑800份、锂长石150‑350份、蛇纹石120‑240份、中性铝溶胶80‑120份、触变剂2‑6份、分散剂8‑14份、增稠剂15‑37份、流平剂3‑11份、水200‑480份。本发明通过在3D打印工艺陶瓷粉体浆料的配方中添加锂长石，锂长石粉状物可以当碱性物大量加入从而作为氧化铝、蛇纹石和晶须硅的助溶剂，由于锂长石熔化本身温度低，会使本3D打印工艺陶瓷粉体浆料的熔点温度降低，拓宽了作为碱性降温矿化物的烧温度范围，从而能是本3D打印工艺陶瓷粉体浆料通过低温烧结的方式进行3D打印。
