Description
Technical field
The present invention relates to ceramic material, particularly relate to good lamellar ceramic honey comb of a kind of plasticity and preparation method thereof.
Technical background
Automobile pollution has become the important sources of China's air pollution, is the weight causing gray haze and photochemical pollution
Want reason.Vehicle exhaust is mainly nitrogen oxides (NOx), Hydrocarbon (HC), carbon monoxide (C0), particulate matter etc., become
For main atmosphere pollution, therefore, the most important thing solving air pollution problems inherent is i.e. to solve automobile exhaust pollution problem.
Automobile exhaust purifier is mainly made up of housing, carrier and catalyst 3 part, and wherein the selection of catalyst is the heaviest
Want.Three-way catalyst refers to remove NO simultaneouslyx, the catalyst of HC, CO these three major pollutants, lot of experiments research table
Bright, rare earth perovskite catalyst La-Sr-Co-O is three-way catalyst, and the good catalytic activity to vehicle exhaust.Zhu Jie exists
Its master thesis " the cordierite honeycomb ceramic load La-Sr-Co-O research to automotive exhaust catalysis performance " uses violet
Cordierite ceramic honey comb is as carrier, and La-Sr-Co-O perovskite composite oxide, as catalyst active component, is prepared for whole
Body formula auto-exhaust catalyst, but its ceramic monolith heat resistance prepared is the highest, and integral catalyzer is once
Damage needs integral replacing, also add use cost while waste resource.
Summary of the invention
For above not enough, it is an object of the invention to provide a kind of high temperature resistant, length in service life, can guarantee that resource is reasonable again
Lamellar ceramic honey comb utilized and preparation method thereof.
The technical problem to be solved uses following technical scheme to realize:
1. the lamellar ceramic honey comb that a plasticity is good, it is characterised in that be made up of the raw material of following weight portion:
Osseocolla 5-10, cordierite 40-50, clay 1-3, ZrO2Powder 5-10, gelatin 2-4, CrO2Powder 5-10, Pulvis Talci 10-15,
Magnesium carbonate 3-5, hydroxypropyl methyl fiber 2-5, sodium carbonate 4-8, stearic acid 1-3,1 mol/L HNO3Solution is appropriate, nano oxygen
Change Alumina gel 50-60,1 mol/L La (NO3)31-3,1 mol/L Sr (NO3)21-2,1 mol/L Co (NO3)2 0.5-1、
1 mol/L citric acid 2-6, deionized water 100-200;
The solid content of described nano alumina sol is 20%-25%.
2. lamellar ceramic honey comb that a kind of plasticity described in is good and preparation method thereof, it is characterised in that include following
Step:
A. the preparation of lamellar ceramic honey comb:
Take osseocolla, cordierite, clay, ZrO2Powder, gelatin, CrO2Powder, Pulvis Talci, hydroxypropyl methyl fiber, magnesium carbonate and carbonic acid
Sodium carries out ball milling, batch mixing, be crushed to 200-500 mesh after, add stearic acid, 50-60 part deionized water mix homogeneously, old
20-25 h obtains pug;Pug is put into after vacuum pugmill carries out mud refining, place into molding rear cutout in single lead screw ex truding briquetting machine
It is segmented into the plate tensile sample of 3-5cm;Put in calcining furnace after drying sample at 100-150 DEG C, at 1200-1500 DEG C, be incubated 1-4h,
Cooling is come out of the stove.
B. the pretreatment of lamellar ceramic honey comb:
After the cordierite honeycomb ceramic plate tensile sample that water-washing step a obtains, use HNO3Solution soaking 20-30 h, uses clear water afterwards
