Abstract

The invention relates to a mining heavy-duty engine coolant which is characterized by comprising the raw materials in percentage by weight as follows: 0.1%-0.2% of TTA, 1.2%-2.6% of sodium hydrogen sebacate, 0.8%-1.4% of triethanolamine oleate soap, 0.6%-1.2% of sodium benzoate, 0.1%-0.2% of tributylamine caprylate, 1.2%-2.0% of a maleic acid-methyl acrylate copolymer, 0.08%-0.2% of sodium hydroxide, 0.01%-0.04% of an anti-foaming agent, 0.65%-1.6% of a coloring agent, 40%-70% of ethylene glycol, and the balance of deionized water. The mining heavy-duty engine coolant guarantees the comprehensive protective capacity of the coolant for 6 metals including soldering tin, brass, red copper, steel, cast iron and cast aluminum in cooling systems of a mine heavy-duty dump truck diesel engine and a mine large-scale construction machinery diesel engine, and particularly improves the corrosion inhibition of the metal copper, so that the performance of a coolant product can achieve long-acting stability, and simultaneously, pollution to human bodies and the environment is reduced.

Description

technical field [0001] The invention relates to a mine-used heavy-duty engine coolant, in particular to a mine-used heavy-duty dump truck and mine large-scale construction machinery diesel engine cooling system. 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....
