3D printing carbon nanotube toughened silicon carbide ceramic-based composite material slurry and preparation method thereof
The invention belongs to the technical field of printing materials, and particularly relates to 3D printing carbon nanotube toughened silicon carbide ceramic matrix composite slurry and a preparation method thereof. The slurry comprises the following components in parts by weight: 58-68 parts of powder particles, 31.4-42.5 parts of a solvent, 0.8-1.2 parts of a binder and 0.3-1.2 parts of a dispersant, wherein the powder particles are silicon carbide, carbon black and carbon nanotubes. The carbon nanotubes are added in the preparation process of the slurry, the mechanical property of the silicon carbide ceramic-based composite material is greatly improved, and the obtained slurry is low in viscosity, high in solid phase content and good in fluidity and can meet the requirements of direct-writing forming 3D printing slurry.
本发明属于打印材料技术领域，尤其涉及一种3D打印碳纳米管增韧碳化硅陶瓷基复合材料浆料及其制备方法。本发明所述浆料包括以下重量份的组分：58‑68份粉体颗粒，31.4‑42.5份溶剂，0.8‑1.2份粘结剂，0.3‑1.2份分散剂，所述粉体颗粒为碳化硅、碳黑、碳纳米管。本发明所述浆料在制备过程中加入碳纳米管，大大提高了碳化硅陶瓷基复合材料的力学性能，所得浆料粘度低、固相含量高、流动性好，能满足直写成型3D打印浆料的需要。
