Problems solved by technology

[0002] In order to save costs, car drivers often directly add tap water to the coolant in the cooling system or replace it with tap water. This practice will cause scaling or rust on the water channel of the cooling system and the wall of the water tank, resulting in poor flow of the coolant and poor heat dissipation performance. Faults such as falling, water tank boiling, engine overheating, etc.
In order to remove the dirt and rust on the inner surface of the cooling system, technicians have tried various methods, the most common of which is to use cooling system cleaning agents for cleaning. The existing cooling system cleaning agents have insufficient cleaning power, which will cause damage to the metal parts of the cooling system. For the problem of large corrosion and poor ability to prevent dirt, a cleaning agent product that can be cleaned and has low corrosion is required

Abstract

The invention discloses an environmentally-friendly cooling system cleaning agent for a vehicle. The cleaning agent is prepared from, by weight, 3-5 parts of aspartic acid, 4-6 parts of glutamic acid,5-8 parts of 1-hydroxyethylidene-1, 2-4 parts of stearic acid, 1-2 parts of lauric acid, 6-9 parts of polymethylacrylic acid, 1-2 parts of methanesulfonic acid, 2-5 parts of ammonium citrate, 1-3 parts of erucic acid, 0.5-1.5 parts of lignosulfonate, 1-2 parts of pine needle extracts, 2-3 parts of tung oil, 0.08-0.1 part of surfactant and 80-120 parts of water. The invention further discloses a preparation method of the environmentally-friendly cooling system cleaning agent for the vehicle. The cleaning agent has the advantages of improving the descaling capacity and lowering the corrosivity.

Description

technical field [0001] The invention relates to the field of cleaning agents for cooling systems. More specifically, the present invention relates to a cooling system cleaning agent for automobiles and a preparation method thereof. Background technique [0002] In order to save costs, car drivers often directly add tap water to the coolant of the cooling system or replace all of it with tap water. This practice will cause scaling or rust on the cooling system water channel and the water tank wall, resulting in poor cooling fluid flow and poor heat dissipation performance. Faults such as falling, water tank boiling, engine overheating, etc. In order to remove the dirt and rust on the inner surface of the cooling system, technicians have tried various methods, the most common of which is to use cooling system cleaning agents for cleaning. The existing cooling system cleaning agents have insufficient cleaning power, which will cause damage to the metal parts of the cooling sys...
