High-strength high-thermal-conductivity precursor ceramic as well as preparation method and application thereof
The invention belongs to the field of 3D printing preparation of precursor ceramics, and particularly relates to a high-strength high-thermal-conductivity precursor ceramic and a preparation method and application thereof, and the method is characterized by comprising the following steps: (1) preparing an organic silicon precursor, an acrylate monomer and a photoinitiator into precursor photosensitive resin; (2) adding boron nitride nanosheets into the precursor photosensitive resin to prepare slurry; (3) preparing a green body with a complex shape by adopting a photocuring 3D printing technology; and (4) carrying out pyrolysis treatment on the obtained green body to obtain the high-strength high-thermal-conductivity precursor ceramic. The preparation method is simple in process and low in preparation cost, the mechanical and thermal properties of the precursor ceramic are improved by adopting the boron nitride nanosheets, and the application field of the precursor ceramic is expanded.
本发明属于先驱体陶瓷的3D打印制备领域，尤其涉及一种高强度高导热先驱体陶瓷及其制备方法和应用，其特征在于，所述方法包括以下步骤：(1)将有机硅先驱体、丙烯酸酯单体、光引发剂配制成先驱体光敏树脂；(2)向先驱体光敏树脂中加入氮化硼纳米片制得料浆；(3)采用光固化3D打印技术制备复杂形状的坯体；(4)将得到的坯体热解处理得到高强度高导热先驱体陶瓷。本发明工艺简单，制备成本低，采用氮化硼纳米片改善先驱体陶瓷的力学和热学性能，拓展了先驱体陶瓷的应用领域。
