Problems solved by technology

Since the water tank radiators of mining vehicles are made of non-ferrous metals such as brass, copper, and solder, common coolants have serious corrosion on the cooling system radiators of mining vehicles, which greatly shortens the service life of mining vehicles.

Abstract

The invention discloses an engine coolant for heavy duty vehicles, which is prepared from the following raw materials in parts by weight: 30-60 parts of ethylene glycol, 2-6 parts of sodium sebacate, 5-9 parts of triethanolamine oleate soap, 3-7 parts of sodium silicate, 2-6 parts of polyacrylic acid, 6-12 parts of sodium benzoate, 2-10 parts of tributyl amine octoate, 6-10 parts of sodium hydroxide, 3-9 parts of benzene dicarboxylic acid, 4-8 parts of organic corrosion inhibitor, 3-7 parts of scale inhibitor, 5-9 parts of defoaming agent, 7-11 parts of salicylic acid and 20-50 parts of deionized water. The engine coolant for heavy duty vehicles has the advantages of favorable corrosion-resistant effect and excellent hard water resistance, can effectively prolong the service life of the antifreezing fluid, and has greatly higher storage and use stability.

Description

technical field [0001] The invention relates to the technical field of cooling liquid, in particular to a heavy-duty vehicle engine cooling liquid. Background technique [0002] Coolant is the cooling medium of the engine circulation cooling system, especially in the cold environment, it can prolong the service life of the engine. At present, the automobile coolant on the domestic market is mainly suitable for ordinary freight vehicles, road heavy vehicles, and passenger cars. However, there are fewer coolants used in the cooling system of diesel engine cooling systems of heavy-duty dump trucks for mining and large-scale engineering machinery in mining. Since the radiators of mining vehicles are made of non-ferrous metals such as brass, copper, and solder, common coolants have serious corrosion on the radiators of the cooling system of mining vehicles, which greatly shortens the service life of mining vehicles.
