Description
Technical Field

Background
The cooling liquid is mainly used for a liquid-cooled engine cooling system, and has the performances of freezing prevention in winter, boiling prevention in summer and scale prevention all the year round. The cooling liquid is formed by mixing different substances, and can be used for lowering the freezing point, efficiently exchanging heat and preventing metal corrosion. At present, cooling liquids used in the market are mainly classified into alcohols, inorganic substances, polysaccharides and the like, wherein the alcohols are used most, and most of the alcohols are water-based cooling liquids of ethylene glycol; the corrosion inhibitor in the cooling liquid mainly adopts silicate, phosphate or organic carboxylic acid, and the cooling liquid is a good choice for a cooling system of a fuel engine.
The existing glycol water-based cooling liquid is mainly produced by adopting a composite formula of inorganic salt and organic corrosion inhibitor, has natural defects in the use period and the storage stability, and has the following defects:
1. in the reaction mechanism, the inorganic salt corrosion inhibitor forms a protective film on the metal surface through a self-consumption process, so that the service life of the product is short. The general vehicles are replaced for two years, and the vehicles with high utilization rate need to be replaced for one year.
2. In terms of storage stability, deposits can occur in the formulation both in use and in storage, resulting in blockage of the engine cooling system and reduced heat transfer efficiency.
3. The addition of phosphate and borate additives to the aqueous solution of ethylene glycol has been found to provide a coolant with a very effective corrosion inhibiting effect on copper and cast iron, but with the widespread use of aluminum alloys in automotive engine cooling systems, the disadvantage of the coolant having a high corrosion on the aluminum surface is gradually apparent, and thus, the addition of silicate additives to the coolant has been found to inhibit the corrosion of the coolant on aluminum and aluminum alloys. And because the silicate is unstable, the storage stability of the cooling liquid containing the silicate is poor, precipitates are easily formed, and the inhibition of the cooling liquid on the corrosion of aluminum and aluminum alloy is influenced.
Therefore, the energy-saving cooling liquid and the application thereof have important practical significance.
