Problems solved by technology

Zhu Jie used cordierite honeycomb ceramics as the carrier in his master's thesis "Study on the Catalytic Performance of Cordierite Honeycomb Ceramics Loaded La-Sr-Co-O on Automobile Exhaust Gas", La-Sr-Co-O perovskite composite oxidation As the active component of the catalyst, a monolithic automobile exhaust catalyst has been prepared, but the heat resistance of the prepared ceramic carrier is not high enough, and once the monolithic catalyst is damaged, it needs to be replaced as a whole, which wastes resources and increases the cost of use.

Abstract

The invention discloses a glass fiber-containing sheet honeycomb ceramic and a production method thereof. The glass fiber-containing sheet honeycomb ceramic is produced from, by weight, 3-5 parts of basalt fibers, 40-50 parts of iolite, 1-3 parts of clay, 3-5 parts of glass fibers, 5-10 parts of ZrO2 powder, 5-10 parts of CrO2 powder, 10-15 parts of talcum powder, 3-5 parts of magnesium carbonate, 5-10 parts of a silane coupling agent KH550, 4-8 parts of sodium carbonate, 1-3 parts of stearic acid, a proper amount of a 1 mol / L HNO3 solution 50-60 parts of nano-alumina sol, 1-3 parts of 1 mol / L La(NO3)3, 1-2 parts of 1 mol / L Sr(NO3)2, 0.5-1 part of 1 mol / L Co(NO3)2, 2-6 parts of 1 mol / L citric acid and 100-200 parts of deionized water. A honeycomb ceramic carrier is processed to form a sheet, so installation and replacement are convenient, the cost is saved, and full utilization of resources is promoted.

Description

technical field [0001] The invention relates to a ceramic material, in particular to a sheet-shaped honeycomb ceramic containing glass fiber and a preparation method thereof. technical background [0002] Motor vehicle pollution has become an important source of air pollution in my country and an important cause of haze and photochemical smog pollution. Vehicle exhaust is mainly nitrogen oxides (NO x ), hydrocarbons (HC), carbon monoxide (C0), particulate matter, etc., have become the main air pollutants. Therefore, the most important thing to solve the air pollution problem is to solve the problem of automobile exhaust pollution. [0003] The automobile exhaust purifier is mainly composed of three parts: the shell, the carrier and the catalyst, among which the selection of the catalyst is very important. Three-way catalyst refers to the ability to remove NO at the same time x , HC, CO these three main pollutants catalysts, a large number of experimental studies have show...
