Formula and preparation method of heat transfer fluid

Abstract

The invention discloses a formula and a preparation method of a heat transfer fluid. The heat transfer fluid comprises the following raw materials by mass: 5-7% of hydrogenated terphenyl, 4-8% of polydodecene, 6-9% of cyanogen-containing silicone oil, 3-5% of a nanometer mixture, 2-4% of trisodium phosphate, 1-2% of sodium sulfate, 3-7% of alcohol, 1-2% of polyepoxysuccinic acid, 5-8% of polyether silicone oil, 2-5% of potassium permanganate, 0.5-1% of alkyl aryl sodium iodate, and 45-84% of pure water. The prepared the heat transfer fluid has a good anti-freezing effect, the phenomenon that the heat transfer fluid is condensed in the standing process in winter is avoided, the heat transfer fluid has good anti-corrosion, corrosion inhibition and anti-scaling effects in the using process, the replacement probability and cost of the heat transfer fluid are reduced, the heat transfer fluid does not have a heat gathering phenomenon in the using process, and the stability of the heat transfer fluid in the using process is improved.

Description

technical field [0001] The invention relates to the technical field of heat transfer liquid, in particular to a formula of heat transfer liquid and a preparation method thereof. Background technique [0002] According to patent 201610372362.2, a method for preparing an environmentally friendly and durable fully synthetic heat transfer fluid is known. The method comprises two steps of base oil synthesis and base oil and auxiliary agent mixing, the base oil is (3-alkyl-1-methyl-imidazole) hexafluorophosphate.

Problems solved by technology

[0004] At present, there are still some deficiencies in the existing heat transfer fluids. For example, the existing heat transfer fluids do not have the antifreeze effect, and the heat transfer fluids are prone to condensation during the standing process in winter, and the heat transfer efficiency is relatively general and easy to deteriorate. Corrosion of pipes and other phenomena, the existing heat transfer fluids have relatively general anti-corrosion, corrosion inhibition and anti-scaling effects during use, which shortens the service life of the heat transfer fluid and increases the probability and cost of heat transfer fluid replacement. It is prone to heat accumulation during use, which reduces the stability of the heat transfer fluid during use
