Preparation method of composite ceramic mold
The invention provides a preparation method of a composite ceramic mold, which belongs to the field of ceramic composite materials. Specifically, the composite ceramic mold is prepared by taking aluminum oxide as a base material, taking modified starch-based phenolic resin as a binder and adding chromium carbide powder and modified diopside powder. Through coordination of all the components, the defect that an aluminum oxide-based ceramic material is fragile is overcome, the obtained ceramic mold is high in hardness, high in fracture toughness, high in bending strength and excellent in wear resistance and thermal shock resistance.
本发明提供了一种复合陶瓷模具的制备方法，属于陶瓷复合材料领域，具体为氧化铝为基材，改性淀粉基酚醛树脂作为粘结剂，并添加碳化铬粉体、改性透辉石粉制得，通过协调各组分，弥补了氧化铝基陶瓷材料的易脆的缺陷，使获得的陶瓷模具硬度大、断裂韧性高、抗弯强度高、耐磨性和抗热震性能优异。
