Preparation method of high-density and high-strength 3D printing silicon carbide ceramic
The invention relates to the technical field of 3D printing, and particularly discloses a preparation method of high-density and high-strength 3D printing silicon carbide ceramic. A preparation method of high-density and high-strength 3D printing silicon carbide ceramic comprises the following steps: powder preparation: adding a silicon carbide material into water, then adding silicon carbide pellets, then adding an alkaline dispersant, and carrying out centrifugal ball milling, drying, scattering and grading to obtain powder; biscuit preparation: hoisting the powder into a storage tank of a 3D printer, mixing sand with a curing agent, and spraying a resin binder by a nozzle for binder jet printing to obtain a biscuit; floating sand is cleaned; degreasing at high temperature; gas phase carburization; impregnating and cracking organic matters; and reactive sintering siliconizing: sintering the green body D at the vacuum degree of 100pa-1000pa and the temperature of 1600-1700 DEG C by using the roasted material to obtain the silicon carbide ceramic.
本申请涉及3D打印的技术领域，具体公开了一种高致密度高强度的3D打印碳化硅陶瓷制备方法。一种高致密度高强度的3D打印碳化硅陶瓷制备方法，包括以下步骤：粉体制备：将碳化硅物料加入到水中，再加入碳化硅小球，接着加入碱性分散剂，离心球磨，干燥、打散、分级，得到粉体；素坯制备：将粉体吊装到3D打印机的储料罐中，与固化剂进行混砂，并由喷头喷出树脂粘结剂进行粘结剂喷射打印，得到素坯；清洗浮沙；高温脱脂；气相渗碳；有机物浸渍裂解；反应烧结渗硅：利用焙烧料对坯体D在100pa‑1000pa真空度、1600‑1700℃下进行烧结，得到碳化硅陶瓷。
