Abstract

The invention discloses anhydrous refrigerating fluid for an internal combustion engine, and relates to the technical field of refrigerating fluid. The anhydrous refrigerating fluid is prepared from the following raw materials in percentage by mass: 85.53 to 95.0 percent of basic liquid, 1.2 to 3.0 percent of nano-particles, 1 to 3 percent of alkaline supplement agent, 0.75 to 1.47 percent of corrosion inhibitor, 0.5 to 2.0 percent of anti-foaming agent, and 2 to 5 percent of additive. A pH value is stabilized at 7.5 to 8.0; the basic liquid is prepared from mixed alcohol of ethylene glycol and propylene glycol; a nano-particle mixture is prepared from copper oxide nano-particles, silicon dioxide nano-particles and aluminum oxide nano-particles; the corrosion inhibitor is prepared from a mixture of sodium benzoate, heptanoic acid, toluene triazole, triazole, isooctanoic acid and diethylene glycol monomethyl ether. The anhydrous refrigerating fluid disclosed by the invention has high performance on comprehensive protection of multiple metals of an automobile cooling system; the complex type anhydrous refrigerating fluid has the advantages of good corrosion inhibitive ability, longlasting property, storage stability, high resistance to hard water, environmental friendliness and safety.

Description

technical field [0001] The invention belongs to the technical field of anhydrous refrigerating fluid, in particular to an anhydrous refrigerating fluid for an internal combustion engine. Background technique [0002] Coolant is an indispensable part of the car engine. It circulates in the engine cooling system to take away the excess heat generated by the engine, so that the engine can run at normal operating temperature. In many areas of the country, automobile coolant is called antifreeze, which has the function of antifreezing in winter (lower than zero in the northern region, and anti-boiling in summer), protecting the cooling system of the engine, improving the heat dissipation effect, and improving engine efficiency. A kind of antifreeze liquid in the heat dissipation system of vehicles with type engines such as automobiles and tractors. Automobile cooling systems are generally composed of copper, brass, aluminum, cast iron, steel, and solder, so the developed coolant ...
