Method for preparing large-size ceramic
The invention provides a method for preparing large-size ceramic, which comprises the following steps of: S1, laminating and mixing solid resin powder and ceramic powder, so that the surface of the ceramic powder is uniformly coated with a layer of solid resin, adding a photoinitiator and a curing agent into the ceramic powder coated with the solid resin, and stirring and mixing at a high speed to obtain printing powder; S2, placing the printing powder in printing equipment for printing forming, adopting a layer-by-layer printing forming method, generating a corresponding printing path of each layer of model through a computer, carrying out powder laying in a roller twisting mode, in the forming process of each layer of powder, scanning the powder through a laser, spraying light-cured resin and glue spraying resin to the powder through two sprayers, irradiating the powder by ultraviolet light, curing and forming, and stacking layer by layer to form a printed biscuit; and S3, sintering the printed biscuit in a sintering furnace to obtain a ceramic green body. The method is suitable for preparing the large-size ceramic green body, the structural strength of the material can be greatly improved, and the deformation quantity is reduced.
本发明提供一种用于制备大尺寸陶瓷的方法，包括以下步骤：S1、将固体树脂粉和陶瓷粉末进行覆膜混料，使得陶瓷粉末表面均匀的包裹一层固体树脂，向包裹固体树脂的陶瓷粉末料中加入光引发剂和固化剂，进行高速搅拌混合得到打印粉料；S2、将打印粉料置于打印设备中，进行打印成型，采用逐层打印成型的方法，每一层模型通过计算机生成相应的打印路径，采用辊撵方式进行铺粉，每一层粉料成型过程中由激光器扫描粉料，由两个喷头分别向粉料喷射光固化树脂和喷胶树脂，再由紫外光照射粉料固化成型，逐层堆积，形成打印素坯；S3、将打印素坯置于烧结炉中烧结获得陶瓷坯体。本发明方法适用于制备大尺寸陶瓷坯体，可以大幅提高材料的结构强度，减小形变量。
