0.5 %-4 % of alcohol；0.5 %-1% of monoethylene glycol monobutyl ether；Water surplus.
Further, the carbon deposit blows down agent as the mixed of butyl acetate, butyl glycol ether, isopropanol and ethyl acetate
It closes, and butyl acetate, butyl glycol ether, the weight ratio of isopropanol and ethyl acetate are 10:4:4:4.
Further, a kind of cleaned and reduced dose of automobile three-element catalytic, consists of the following components in percentage by weight:Carbon deposit
Blow down 5 % -8% of agent；Sodium hydroxide 0.5%-1%；Tetrasodium ethylenediamine tetraacetate 0.3%-4%；0.5 %-2 of nonylphenol polyoxyethylene ether
%；0.5 %-2% of isopropanol；0.5 %-0.8% of monoethylene glycol monobutyl ether；Water surplus.
The present invention also provides a kind of preparation methods of cleaned and reduced dose of automobile three-element catalytic, include the following steps：
1）Butyl acetate, butyl glycol ether, isopropanol and ethyl acetate are mixed evenly, carbon deposit is made and blows down agent；
2）Tetrasodium ethylenediamine tetraacetate, nonylphenol polyoxyethylene ether, isopropanol, monoethylene glycol monobutyl ether, water are mixed equal
It is even, sodium hydroxide is slowly added to, is stirred evenly；
3）Carbon deposit is blown down into agent and adds in step 2）In, it stirs evenly.
Compared with prior art, the invention has the advantages that：
The carbon deposit that the present invention adds blows down agent, plays an important role of cleaning to ternary catalyzing unit surface attachments, decomposes.It is added to clear
It washes in reducing agent system, has the characteristics that cleaning speed is fast, effect is good, can thoroughly remove sulfide, phosphorus in ternary catalyzing unit
Compound and carbon distribution allow ternary catalyzing unit to keep good working order.The present invention can effectively recover ternary catalyzing unit surface-active,
The harmful substance in Vehicular exhaust is reduced, solves the problems, such as tail gas pollution, existing automobile is avoided and reduces exhaust pollutant discharge
Technology in, cleaning agent carry out administer tail gas by way of it is poor there are cleaning effect, can not effectively reduce pollution emission
The problem of object.
