Preparation method of integral honeycomb cordierite carrier
The invention discloses a preparation method of an integral honeycomb cordierite carrier, which comprises the following steps: (1) immersing a honeycomb cordierite matrix A into alumina sol containing a physical pore-enlarging agent for primary coating, then drying, and roasting in an inert atmosphere to obtain a primarily coated matrix B; (2) immersing the matrix B into an epoxy propane aqueous solution, carrying out a reaction in a sealed reaction kettle, and then carrying out drying treatment to obtain a matrix C; and (3) immersing the matrix C into the alumina sol for secondary coating, then drying, and roasting in an oxygen-containing atmosphere to obtain the integral honeycomb cordierite carrier. The carrier coating has stepped pore channel distribution, the coating firmness is high, the preparation process is simple, and practical industrial application is facilitated.
本发明公开了一种整体式蜂窝状堇青石载体的制备方法，包括如下内容：（1）蜂窝状堇青石基体A浸入到含有物理扩孔剂的氧化铝溶胶中进行一次涂覆，然后进行干燥，惰性气氛下焙烧，得到一次涂覆的基体B；（2）将基体B浸入环氧丙烷水溶液中，在密封反应釜中进行反应，然后干燥处理，得到基体C；（3）将基体C浸入到氧化铝溶胶中进行二次涂覆，然后进行干燥，在含氧气氛中焙烧处理，得到整体式蜂窝状堇青石载体。载体涂层中具有梯级孔道分布，涂层牢固度高，制备过程简单，有利于实际工业应用。
