Problems solved by technology

However, the adsorption film formed by the organic acid corrosion inhibitor is thin (only a few nanometers) and not dense, which leads to its unsatisfactory anti-corrosion effect on solder and aluminum alloys, especially heat transfer corrosion of cast aluminum and aluminum pump cavitation corrosion

Abstract

The invention discloses a fullerol containing organic type engine liquid coolant and a preparation method thereof. The liquid coolant comprises the following components in parts by weight: 30 to 95 parts of dihydric alcohol, 5 to 70 parts of deionized water, 0.01 to 2 parts of fullerol, 0.5 to 5.0 parts of organic acid corrosion inhibitor, 0.01 to 0.5 part of azoles corrosion inhibitor, 0.001 to 0.01 part of antifoaming agent, and 0.01 to 0.05 part of dye. Fullerol and organic acid corrosion inhibitor in the liquid coolant can generate a synergistic effect, are adsorbed on the surface of metals, and form a compact fullerol / organic acid protective film, so the liquid coolant has a comprehensive anticorrosion effect on purple copper, yellow copper, carbon steel, cast iron, soldering tin, and cast aluminum and especially has an excellent performance on resisting heat transfer corrosion of cast aluminum and cavitation corrosion of aluminum pump.

Description

technical field [0001] The invention relates to the field of engine coolant, in particular to an organic engine coolant containing fullerenol and a preparation method thereof. Background technique [0002] Engine coolant is an indispensable part to maintain the normal work and operation of the engine. Coolant is the heat transfer medium of the engine cooling system, which plays the role of cooling, anti-corrosion, anti-scaling, anti-freezing and so on. Coolant is usually composed of water, antifreeze, corrosion inhibitor, scale inhibitor, colorant, defoamer, etc. According to the composition of corrosion inhibitors, engine coolants can be divided into inorganic type coolants based on inorganic salt corrosion inhibitors and organic type coolants based on organic acid corrosion inhibitors. [0003] At present, inorganic type coolants are mostly used in China, and the main inorganic salt corrosion inhibitors used are silicates, borates, molybdates, phosphates, etc. Inorganic...
