Core-shell-shaped black ceramic particle for 3D printing and preparation method and application thereof
The invention belongs to the technical field of black powder ceramic and composite ceramic additive manufacturing, and particularly relates to a core-shell-shaped black ceramic particle for 3D printing and a preparation method and application thereof. The core-shell-shaped black ceramic particle for 3D printing comprises a black ceramic matrix and a coating layer, and the thickness of the coating layer is 50-100 nm; the material of the coating layer is selected from metal oxides. The preparation method comprises the following steps: uniformly dispersing the black ceramic matrix in a precursor suspension, carrying out a polymerization reaction under a certain condition, forming a modified layer with a certain space structure on the surface layer of the coated black ceramic matrix, and carrying out drying and heat treatment to obtain the required powder material coated with the low-scattering and reinforced phase modified layer. The absorption and scattering of the black ceramic material on ultraviolet light in the photocuring process are reduced. Meanwhile, the ceramic material prepared from the core-shell-shaped black ceramic particle through 3D printing is large in thickness and excellent in compactness and mechanical property.
本发明属于黑色粉末陶瓷及复合陶瓷增材制造技术领域，具体涉及一种用于3D打印的核壳状黑色陶瓷颗粒及其制备方法和应用。用于3D打印的核壳状黑色陶瓷颗粒，包括：黑色陶瓷基体和包覆层，所述包覆层厚度为50‑100nm；所述包覆层材料选自金属氧化物。本发明将黑色陶瓷基体均匀分散在前驱体悬浮液中，在一定条件下发生聚合反应，在被包覆黑色陶瓷基体表层形成具有一定空间结构的改性层，经干燥和热处理后得到所需的包覆有低散射与增强相改性层的粉体材料，降低黑色陶瓷材料对光固化过程中紫外光的吸收和散射。同时核壳状黑色陶瓷颗粒经3D打印制备的陶瓷材料厚度较大，致密性和力学性能优异。
