Ceramic slurry, false tooth composite material and preparation method and application thereof
The invention discloses ceramic slurry, a false tooth composite material and a preparation method and application thereof, and relates to the technical field of ceramic materials. The ceramic slurry comprises N parts of independent slurry, the slurry is obtained by uniformly mixing ceramic fine powder, pigment, a dispersing agent and a gel forming agent in a solvent and carrying out vacuum defoaming, and the gel content of the slurry is 0.2-2%; the mass content of the pigment in the slurry from the first part to the Nth part is gradually reduced, the content of the ceramic fine powder is gradually increased, and the ceramic slurry is heated to 55-70 DEG C during use. The gradient control of the pigment content of the N parts of slurry and the content of the ceramic fine powder is combined with a freezing pouring method and a multi-time gel method, so that the interlayer continuity of the false tooth composite material is ensured, the bending strength of the false tooth composite material is improved, the gradient gradual change of color and transparency is realized, and the artificial tooth is better matched with the original tooth.
本发明公开了一种陶瓷浆料、义齿复合材料及其制备方法和应用，涉及陶瓷材料技术领域。本发明的陶瓷浆料包括独立存在的N份浆料，所述浆料为陶瓷细粉、色料、分散剂和凝胶成型剂混匀于溶剂中，经真空脱泡得到，浆料的凝胶含量为0.2～2％；且从第一份至第N份浆料的色料质量含量逐渐降低，陶瓷细粉的含量逐渐升高，所述陶瓷浆料使用时加热至55～70℃。本发明其中N份浆料的色料含量和陶瓷细粉的含量梯度控制结合冷冻浇筑法和多次凝胶法，保证义齿复合材料层间连续性，提升义齿复合材料的抗弯强度，且实现色彩和透明度梯度渐变，更匹配原生牙。
