Problems solved by technology

The traditional solution is mechanical dredging. This method is not only time-consuming, expensive, but also easy to break the water tank. More importantly, it cannot remove the scale in the circulating pump and the internal circulating water of the engine.
The cleaning products currently used in the market are basically inorganic strong acids, which are easy to corrode the water tank of the car cooling system and the internal circulation water of the engine. Frequent use will cause the car cooling system to lose its proper heat dissipation function and be scrapped

Abstract

The invention belongs to the technical field of cleaning an automobile cooling system, and particularly discloses a cleaning agent of the automobile cooling system and a preparation method thereof. The cleaning agent of the automobile cooling system mainly comprises the following components in percentage by weight: 10 to 12 percent of glycollic acid, 5 to 8 percent of sulfonic acid, 3 to 6 percent of acid cleaning inhibitor and the balance of water. The preparation method comprises the following steps of: (1) taking water, adding the sulfonic acid and the glycollic acid into the water, and then uniformly stirring the mixture; and (2) adding the acid cleaning inhibitor into the mixture obtained in the step (1), and then uniformly stirring the latter mixture to obtain a finished product. The cleaning agent is subjected to a large number of scientific experiments and internal practical application for years to prove that the cleaning agent not only has high cleaning and pollutant removaleffects, but also overcomes the defect of corrosion.

Description

technical field [0001] The invention belongs to the technical field of cleaning of automobile cooling systems, and in particular relates to a cleaning agent for automobile cooling systems and a preparation method thereof. Background technique [0002] The cooling system of the car is responsible for absorbing and evacuating the heat generated by the engine, improving the efficiency of the engine and prolonging its service life. Different vehicles have different cooling system materials, but they are mainly composed of copper, solder and aluminum. Due to water quality reasons, after long-term use of water, scales will form on the circulating water pipes of the automobile engine and inside the water tank as a radiator, and dirt such as antifreeze decomposition products will adhere to it, which will block the water tank or circulating water channel, resulting in the temperature of the circulating water rising or even Boiling will seriously affect the normal operation of the ve...
