Preparation of 3D rapid prototyping alumina-zirconia-carbon ceramic powder material
The invention discloses a method for preparing a 3D rapid prototyping alumina-zirconia-carbon ceramic powder material. The method is characterized by comprising the following steps: firstly, pre-treating alumina-zirconia-carbon ceramic powder with N-(beta-aminoethyl)-gamma-amino propyl trimethoxy silane and stearic acid to obtain pre-treated alumina-zirconia-carbon ceramic powder; then, adding the following components in percentage by mass: 60-70 percent of trichloroethane and 2-5 percent of bisphenol A polycarbonate into a reactor, stirring and dissolving, and adding 26-36 percent of the pre-treated alumina-zirconia-carbon ceramic powder, uniformly stirring and mixing, intensively stirring at constant temperature of 50+/-5 DEG C, refluxing to react for 5-7 hours, and drying by spraying to obtain the rapid prototyping alumina-zirconia-carbon ceramic powder material. The material does not need to spray adhesive, can be directly molded in a molding temperature range of 220-230 DEG C, has the advantages of simple preparation process, easily controlled condition and low production cost, and is easy for industrial production.
