3D-printing-based integral cordierite honeycomb ceramic carrier and preparation method thereof
The invention discloses a 3D-printing-based integral cordierite honeycomb ceramic carrier and a preparation method thereof. The raw materials of the cordierite honeycomb ceramic carrier comprise light-cured mixed photosensitive resin consisting of photosensitive resin and cordierite powder. The preparation method comprises the following steps: fully mixing the raw materials of the photosensitive resin in ultrasound; fully ball-milling photosensitive resin and cordierite powder in a ball mill, and removing bubbles under a vacuum drying condition to prepare light-cured mixed photosensitive resin; using modeling software for conducting three-dimensional structure design, printing light-cured mixed photosensitive resin through a DLP light-cured printer, and after printing is finished, placing a printed structure in absolute ethyl alcohol to be fully cleaned; and evaporating, pyrolyzing the organic matters, and sintering to obtain the integral cordierite honeycomb ceramic carrier. The integral cordierite honeycomb ceramic carrier formed by using the DLP printing technology is not limited by the size and shape of a mold, and the honeycomb ceramic carrier which is complex in shape, high in pore density and ultra-thin in partition wall can be manufactured.
本发明公开了一种3D打印整体式堇青石蜂窝陶瓷载体及其制备方法。所述堇青石蜂窝陶瓷载体的原料包括由光敏树脂树脂与堇青石粉体组成的光固化混合光敏树脂。制备方法为：将光敏树脂的原料超声中充分混合；将光敏树脂与堇青石粉体于球磨机中充分球磨，于真空干燥条件下排除气泡，制得光固化混合光敏树脂；使用建模软件进行三维结构设计，将光固化混合光敏树脂使用DLP光固化打印机进行打印，打印结束后将打印结构置于无水乙醇中进行充分清洗；蒸发、热解有机物，烧结，得到整体式堇青石蜂窝陶瓷载体。本发明利用DLP打印技术成型的整体式堇青石蜂窝陶瓷载体，不受模具大小和形状的限制，可制造形状复杂、高孔密度、超薄间壁的蜂窝陶瓷载体。
