The purifying agent for automobile exhaust is prepared form the following components in percentage by weight: 10-30% of urea, 0.1-2% of a scale inhibitor, 0.5-15% of an acid-binding agent, 0.01-1% of a corrosion inhibitor, a pH regulator with the amount required for regulating the pH, and the balance being water. The purifying agent for automobile exhaust disclosed by the invention is reasonable in formulation design, and capable of effectively removing hazardous substances of NOx and CO which cause serious pollution to environment in the automobile exhaust in case of being used in cooperation with a purification device for automobile exhaust; and moreover, the scale inhibitor and the corrosion inhibitor added in the formulation are capable of achieving an excellent corrosion inhibition effect, effectively preventing the rusting of a metal material, and protecting the purification device for automobile exhaust, thus prolonging the service life.
Description
Technical field
The present invention relates to a kind of car tail gas purificant and preparation method thereof.
Background technology
The composition of vehicle exhaust contains CO
2
, CO, NOx, oil gas, materials such as ashes, these materials bring serious pollution to the direct discharging meeting of environment to environment.Vehicle exhaust is to the acid rain in some areas, and the serious haze of north of china in winter has inescapable responsibility, common people's key health has been caused great harm, so the improvement of vehicle exhaust is extremely urgent.
Along with improving constantly of people's living standard, automobile is entering vast family fast as the sign of life high level.People's living standard has improved, automobile industry development, the thing followed is exactly that the emission of automobile wastes amount has increased, and vehicle exhaust has also strengthened the influence of environment, and acid rain is many, and haze is serious, has had a strong impact on people's health.
Vehicle exhaust is increasing to the influence of environment, so the improvement of tail gas is just more and more important.At present the improvement method of vehicle exhaust is multifarious, what weighing method no matter, and purpose has only one namely to reduce vehicle exhaust to discharging, the protection atmospheric environment of environment.No matter be which kind of improvement method, all must use cleanser in the prior art, the prescription of cleanser directly affects the effect that purifying vehicle exhaust is handled.In the prior art, bigger to the corrosion of exhaust gas cleaner though some cleanser can play clean-up effect preferably, reduced the long-term effect of tail gas clean-up and the service life of having reduced exhaust gas cleaner.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, a kind of multi-purpose vehicle(MPV) purification agent for treating waste gas is provided, it not only can both play governance role to the most harmful substance in the vehicle exhaust, and little for the corrosion of the purifier that uses this car tail gas purificant.
The present invention also provides a kind of preparation method of car tail gas purificant simultaneously, this method gained car tail gas purificant not only can both play governance role to the various harmful substances in the vehicle exhaust, and little for the corrosion of the purifier that uses this car tail gas purificant.
