3D printing ceramic composite material and preparation method and application thereof
The invention discloses a 3D printing ceramic composite material as well as a preparation method and application thereof. The preparation method comprises the following steps: preparing raw materials in parts by weight; the preparation method comprises the following steps: (1) mixing 0.5-20 parts of a photopolymerizable prepolymer, 3-35 parts of a photopolymerizable monomer, 0.5-5 parts of a photoinitiator, 0.5-10 parts of an up-conversion luminescent material, 0.25-5 parts of a surfactant and 60-95 parts of ceramic powder to prepare 3D printing ceramic ink; (2) carrying out near-infrared light assisted ink direct writing 3D printing on the ceramic ink according to a preset program structure to obtain a three-dimensional ceramic structure preform; and (3) degreasing and sintering the preformed part to obtain a ceramic part, namely the 3D printing ceramic composite material. The obtained ceramic composite material has specific fluorescence characteristics under excitation of near-infrared laser, and can be widely applied to the fields of counterfeiting prevention, temperature detection and the like.
本发明公开了一种3D打印陶瓷复合材料及其制备方法与应用，所述制备方法包括如下步骤：各原料以重量份数计；(1)将0.5～20份可光聚合预聚体、3～35份可光聚合单体、0.5～5份光引发剂、0.5～10份上转换发光材料、0.25～5份表面活性剂和60～95份陶瓷粉体混合，制得3D打印陶瓷墨水；(2)按照预定的程序结构将陶瓷墨水进行近红外光辅助墨水直写3D打印，得到三维陶瓷结构预成型件；(3)将预成型件进行脱脂和烧结，得到陶瓷器件，即所述3D打印陶瓷复合材料。本发明得到的陶瓷复合材料在近红外激光激发下具有特定的荧光特性，可广泛应用于防伪、温度探测等领域。
