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 organic engine cooling liquid containing carboxylated fullerene and a preparation method thereof. The organic engine cooling liquid contains the following components in parts by weight: 30-95 parts of dihydric alcohol, 5-70 parts of deionized water, 0.01-1 part of carboxylated fullerene, 0.5-5.0 parts of organic-acid corrosion inhibitor, 0.01-0.5 part of imidazoline corrosion inhibitor, 0.001-0.01 part of defoaming agent and 0.01-0.05 part of dyestuff. The organic engine cooling liquid and the preparation method disclosed by the invention have the advantages that by synergistic effect of the carboxylated fullerene and the organic-acid corrosion inhibitor and absorption on the metal surface, a dense fullerene/organic-acid protective film is formed, so that the comprehensive corrosion-resistant effect for purple copper, yellow copper, carbon steel, cast iron, soldering tin and cast aluminium can be achieved, and especially the resistance to heat-transferring corrosion of the cast aluminium and cavitation corrosion of an aluminium pump is excellent.

Description

technical field [0001] The invention relates to the field of engine coolant, in particular to an organic engine coolant containing carboxylated fullerene 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...
