1. a kind of manufacturing method of ceramic honeycomb structural body, which is characterized in that the ceramic honeycomb structural body includes ceramic honeycombBody and periphery wall, the ceramic honeycomb body has the multiple ducts for being formed and being axially extended by the next door of Porous, described outerPeripheral wall is formed in the periphery of the ceramic honeycomb body,The manufacturing method includesExtruded ceramic base soil, forms the process with the formed body of ceramic honeycomb;

  • By being processed to the formed body or by the peripheral part of the sintered body after formed body firing, to remove positionA part in the next door in the duct of peripheral part obtains the work for the ceramic honeycomb body for having the groove axially extended in outer peripheral surfaceSequence;

    WithCoating material is coated in the outer peripheral surface of the ceramic honeycomb body and forms periphery wall, and the two of the ceramic honeycomb bodyThe edge part of end face is coated with coating material, pushes to the coating material for being coated on the edge part and sets between central portion and edge partThe pressing fixture of stepped ladder circle plate is set to apply load, is inserted into formation sealing in the duct of the edge part,Simultaneously expose part of it and forms the adjacent sealing and the periphery wall of connection in the edge part of the both ends of the surfaceResidual coating material layer process,In the drying of coating material, it is difficult to generate gap between the periphery wall and the groove.
