Preparation method of ceramic mold material
The invention discloses a preparation method of a ceramic mold material, and belongs to the field of ceramic mold materials. The preparation method comprises the following steps: uniformly mixing a powder for the ceramic mold material with deionized water to prepare a mixed slurry, placing the mixed slurry in a mold, standing, drying, demolding to obtain a ceramic mold material green body, and carrying out high-temperature sintering to obtain the ceramic mold material. The preparation method of the powder for the ceramic mold material comprises the step of uniformly grinding alpha-aluminum oxide powder, aluminum borate whiskers, tin oxide powder, zirconium oxide bead powder and polyurethane/asbestos nano composite material powder under the action of mechanical grinding to obtain the powderfor the ceramic mold material. The powder for the ceramic mold material used in the preparation method is good in dispersity and uniform in particle, and the ceramic mold material which is good in fracture toughness and abrasion resistance, high in strength and high in hardness can be obtained.
本发明公开了一种陶瓷模具材料的制备方法，属于陶瓷模具材料领域，其制备方法为：将陶瓷模具材料用粉体与去离子水混合均匀，制得混合浆料，将混合浆料置于模具中，静置与干燥，脱模，得到陶瓷模具材料生坯，再经过高温烧结，得到陶瓷模具材料。上述陶瓷模具材料用粉体的制备方法包括：将α‑氧化铝粉体、硼酸铝晶须、氧化锡粉体、氧化锆珠粉体、聚氨酯/石棉纳米复合材料粉体在机械研磨作用下研磨均匀，得到陶瓷模具材料用粉体。本发明制备方法所用陶瓷模具材料用粉体分散性好、颗粒均匀，可得到断裂韧性与耐磨性好，高强度与高硬度的陶瓷模具材料。
