Metal carrier for automobile tail gas purifier catalyst and its prepn

Abstract

The present invention relates to metal carrier for automobile tail gas purifier catalyst and its preparation process, and solves the technological problem in providing metal carrier with simple formation process and low production cost. The metal carrier features its 3D netted structure with skeleton of metal nickel or nickel coated copper, and has porosity of 30-98 %, pore number of 20-60 PPI and pore size of 0.5-3 mm. The preparation process includes the following steps: treating foamed polyurethane or polyether plastic via chemical plating or vacuum vapor depositing to coat carbon-base conducting material; electrically depositing matrix metal of nickel or copper coated nickel; and burning out foamed plastic base in a pyrolysis oven. The metal carrier is mainly used as carrier for automobile tail gas purifier catalyst.

Description

Technical field:

[0001] The present invention relates to a novel high-efficiency automobile exhaust purifier metal carrier material and a preparation method thereof, in particular to a novel foamed metal carrier material which can be used as a high-efficiency automobile exhaust purifier and a preparation method thereof. The foamed metal carrier material has a unique three-dimensional The mesh honeycomb structure has the characteristics of high porosity, large specific surface area, small wind resistance, high temperature resistance, oxidation resistance, small heat capacity, high thermal conductivity and long life. The utility model belongs to the field of automobile exhaust purification. Background technique:

[0002] With the rapid growth of automobile ownership, the pollution of urban environment by automobile exhaust is becoming more and more serious. The effective measure to solve this problem is to install automobile exhaust purification mufflers. In automobile exhaust...
