Problems solved by technology

Although the various raw materials used in this invention interact with each other and have a good cleaning effect, it can be cleaned at room temperature, but this invention needs to be used after the three-way catalytic converter is cooled to below 50 ° C, and in many emergencies After the car starts, the temperature cannot be cooled in time and the three-way catalytic converter needs to be cleaned, so it is necessary to develop a cleaning agent that has good cleaning effects at different temperatures

Abstract

The present invention discloses a vehicle three-way catalytic converter cleaning agent, which comprises, by weight, 8-30 parts of a carbon dissolving agent, 32-70 parts of an organic acid, 10-80 partsof a fatty acid condensation substance, 5-50 parts of a sodium salt surfactant, 1-14 parts of a long-chain alkyl quaternary ammonium salt, 1-4 parts of a chelating agent hexadecyl trimethyl ammoniumbromide, 4-16 parts of limonene, and 740-930 parts of softened water, wherein the carbon dissolving agent comprises cyclohexane and nanometer titanium dioxide. According to the present invention, thevehicle three-way catalytic converter cleaning agent can provide good cleaning effect at room temperature, and can further provide good cleaning effect if the three-way catalytic converter cannot be cooled after the vehicle is started.

Description

technical field [0001] The invention relates to the technical field of automobile cleaning agents, more specifically, it relates to an automobile three-way catalytic converter cleaning agent and a preparation method thereof. Background technique [0002] The three-way catalytic converter is installed in the exhaust system of the car, and its function is to reduce most of the exhaust gas pollutants such as hydrocarbons, carbon monoxide, and nitrogen oxides emitted by the engine. When the automobile engine exhausts through the exhaust pipe, when the three gases of carbon monoxide, hydrocarbons and nitrogen oxides pass through the three-way catalytic converter of the automobile, the grids coated with rare and precious metals such as rhodium, platinum, and palladium layers as catalysts are respectively spaced, and the gas is enhanced. The activity of the three gases is determined, and the oxidation-reduction chemical reaction is carried out through the combustion in the three-wa...
