High-density amorphous calcium phosphate nano powder as well as preparation method and application thereof
The invention discloses a high-density modified amorphous calcium phosphate nano powder. The nano powder comprises the following components in parts by weight: 1-5 parts of layered silicate, 100-400 parts of calcium salt and 100-400 parts of phosphate, wherein the layered silicate comprises 1-5 parts of rare earth substances, 20-50 parts of calcium salt, 1-5 parts of sodium chloride and 20-60 parts of water glass. The preparation method comprises the following steps: A, preparing layered silicate; and B, preparing amorphous calcium phosphate nano powder. The nano powder is used for a biomedical 3D printing material. By effectively improving the density of ACP powder, the technical problem that the printing precision is poor when the ACP powder is applied is solved. When the nano powder isused as a powder material for 3D printing and water or dilute acid is used as a matched bonding solution, the ACP powder is high in density, the phenomenon of powder flying in the printing process isavoided, and the printing precision is greatly improved. A prepared high-precision living body skeleton is implanted into a solid finished product and can meet the clinical application requirements ofskeleton transplantation repair treatment.
本发明所述的高密度改性无定形磷酸钙纳米粉体，包括1～5份层状硅酸盐、100～400份钙盐、以及100～400份磷酸盐；其中，所述层状硅酸盐包括1～5份稀土物质、20～50份钙盐、1～5份氯化钠、以及20～60份水玻璃。本发明所述的制备方法包括：A层状硅酸盐的制备；B无定形磷酸钙纳米粉体的制备。本发明用于生物医学3D打印材料。本发明通过有效提高ACP粉末的密度解决了其应用时打印精度差的技术难题。将本发明粉体作为3D打印的粉末材料，水或稀酸等为配套的粘结溶液时，由于ACP粉体密度高，不会在打印过程中出现“飞粉”现象，极大地提高了打印精度。制备的高精度生物体骨骼植入实体成品，能够满足骨骼移植修复治疗临床应用要求。
