Description

Automobile three-way catalytic converter curing agent without dismantling and cleaning and preparation method thereof
Technical field
The invention belongs to automobile-used maintenance field of chemicals, and in particular to automobile three-way catalytic converter curing agent without dismantling and cleaning and Its preparation method.
Background technology
Three-way catalytic converter is mounted in most important outer purifier, operation principle in automobile exhaust system：It will Three kinds of main pernicious gases of vehicle exhaust discharge：CO, HC and NOX (are mostly by the catalyst in three-way catalytic converter The activity of three kinds of gas is added during platinum (Pt), Palladium (Pd) and rhodium (Rh) are made when rare metals), carries out oxidation-reduction chemistry Reaction, wherein：CO is oxidized to colourless, nontoxic CO under the high temperature conditions2Gas；HC compounds are oxidized to H under the high temperature conditions2O And CO2；NOX is reduced into N2And O2.Three kinds of harmful exhausts become innocuous gas, and the tail gas of discharge is purified.
Three-way catalytic converter failure producing cause：Catalyst is very sensitive to elements such as sulphur, lead, phosphorus, zinc, sulphur and lead source From the harmful substance in fuel oil；Phosphorus and zinc are derived from lubricating oil.These four substances and they burn within the engine after formed Oxide particle be easily attracted to catalyst, form chemical complex inside lambda sensor surface and three-way catalytic converter. Further, since the custom of driver or it is long-term exercise in congestion or ice and snow road conditions, engine is often in imperfect combustion work Condition：Carbon deposit poison deactivation is formed inside lambda sensor surface and three-way catalytic converter, blocks and EGR valve is deposited object resistance The failures such as fork clip is stagnant, cause that engine work is abnormal, and oil consumption increases, and power dropping, exhaust emissions be exceeded or even exhaust emissions Temperature excessively high the problems such as causing vehicle spontaneous combustion.
Patent CN101884940A《The regenerative agent and processing method of automobile three-way catalysts》Be it is a kind of because occur ternary urge After changing reactor failure, and stop and processing method is carried out to three-way catalytic converter by the way of " drip ".Patent CN101982542A《Special cleaning agent for three-way》Be it is a kind of because occur three-way catalytic converter failure after, especially In the case that engine can not start, using three-way catalytic converter is removed, impregnate using pneumatic spray gun or in container or Utilize the processing method of supersonic wave cleaning machine.The purpose of three-way catalytic converter curing agent without dismantling and cleaning of the present invention is to prevent to be It is main, supplemented by cleaning, under conditions of normally driving is not influenced, maintaining is carried out to three-way catalytic converter.
The content of the invention
It is an object of the present invention to provide a kind of automobile three-way catalytic converter curing agents without dismantling and cleaning and preparation method thereof.This hair Bright is to aim at prevention,, whenever and wherever possible all can be to three-way catalytic converter under conditions of normally driving is not influenced supplemented by cleaning Carry out maintaining.
Above-mentioned purpose is achieved through the following technical solutions：
A kind of automobile three-way catalytic converter curing agent without dismantling and cleaning, the automobile three-way catalytic converter maintenance without dismantling and cleaning Agent is 30~60 parts of dimethoxy-ethane by parts by weight, 15~24 parts of hexamethylene, 5~8 parts of o-dichlorohenzene, 6~9 parts 1,2- dichloroethanes, 4~8 parts of tetrahydronaphthalene, 4~7 parts of 2- hydroxypropyl butyl ethers, 3~6 parts of hexamethylene -1,2- bis- Carboxylate, 3~8 parts of n-butanol and 0.005~0.05 part of T1201 compositions.
