Abstract

The invention provides a silicon-containing organic engine coolant, which comprise, by weight, 25-55 parts of ethylene glycol, 2-10 parts of a carboxylate, 0.1-5 parts of a silicate, 0.1-5 parts of asilicate stabilizer, 0.5-10 parts of a corrosion inhibitor, 0.2-2 parts of a preservative, 0.5-2 parts of an antifoaming agent, and 30-70 parts of deionized water. According to the present invention,the silicon-containing organic engine coolant can well protect the metal and non-metal materials of the engine cooling system, can effectively prevent corrosion and water scale, and has stability andlong service life within a large pH value range.

Description

technical field [0001] The invention relates to an engine cooling liquid, in particular to a liquid used in a motor vehicle engine cooling system for anti-freezing, anti-boiling, anti-scaling and anti-corrosion of the cooling system, which belongs to the field of chemical industry. Background technique [0002] The engine coolant is mainly used in the cooling system of the automobile engine, as the heat transfer medium of the cooling system, to dissipate the heat in time to ensure that the engine works at a suitable temperature. [0003] The main components of the engine cooling system include thermostats, water pumps, water pump belts, radiators, cooling fans, water temperature sensors, liquid storage tanks, heating devices, etc., and the materials include various metals, rubber, plastics, etc. The requirements for engine coolant mainly include anti-freezing, anti-boiling, anti-scaling, anti-corrosion, and no damage to rubber parts. With the miniaturization of the engine a...
