The honeycomb structure type catalyst and manufacturing method that the utility model, which is provided, can prevent catalyst pulp from leaching in the honeycomb structure of sheath portion when carrying out catalyst-loaded washcoated, can ensure that when as diesel particulate filter device (GPF) aeration of sheath portion and do not crack.A kind of honeycomb structure etc., it is the honeycomb structure for the catalyst manufacture that the sheath portion of the monolith substrate of the sheath portion in the spaced walls comprising the Porous for forming multiple cells and Porous has resin combination, it is characterized in that, the crust of aforementioned cellular base material is formed with spaced walls by homogeneous material, the porosity is more than 50%, aforementioned resin is infiltrated in the pore of crust universe, and invasive depth is equivalent to the part of skin thickness or resin combination and is deeper infiltrated than crust and to reaching cell spaced walls. |
