Long-service-life multi-protection coolant

Abstract

The invention discloses a long-service-life multi-protection coolant. The coolant is prepared from a propylene glycol and ethylene glycol blend, citric acid, simethicone, sodium silicate, starch, glycerol, tribasic polycarboxylic acid, a formic acid and acetic acid mixture, a succinic acid and dodecanedioic acid mixture, montmorillonite nano-particles, a lauric acid and palmitic acid mixture, nano-alumina and guar gum by weight. The coolant is good in cooling performance, the problems that due to gel polymerization of traditional silicate in a coolant, the corrosion inhibition of the coolant is reduced, and a pipeline is blocked are solved, and the problem that an existing engine coolant lacks the protection function for cast aluminum components of a cooling system is also solved; the ingredient composition of the coolant is improved, various comprehensive properties of the coolant are improved, soldering tin of the cooling system is greatly protected, pitting corrosion caused by the engine coolant to the engine cooling system is greatly reduced, and the protection performance of inhibiting cavitation corrosion is improved.

Description

technical field [0001] The invention relates to the technical field of cooling fluid, in particular to a high-life multi-protection cooling fluid. Background technique [0002] Coolant is a complex multi-component system. An excellent coolant should have functions such as heat dissipation, anti-corrosion, anti-freezing, high boiling point, anti-scale and anti-foaming. Most antifreezes have been eliminated due to various reasons, such as methanol and ethanol have low boiling points, high vapor pressure and are flammable; salt water mixtures are prone to rust and crystal precipitation; glycerin has high viscosity, poor antifreeze performance, and is incompatible with rubber; Ethylene glycol has high low-temperature viscosity and poor anti-rust ability, etc., and the existing engine coolant in my country lacks protection for the cast aluminum parts of the cooling system, lacks protection for the solder in the cooling system, and the pitting corrosion of the engine cooling system...

AI Technical Summary

Problems solved by technology

Most antifreezes have been eliminated due to various reasons, such as methanol and ethanol have low boiling points, high vapor pressure and are flammable; salt water mixtures are prone to rust and crystal precipitation; glycerin has high viscosity, poor antifreeze performance, and is incompatible with rubber; Ethylene glycol has high low-temperature viscosity and poor anti-rust ability, etc., and the existing engine coolant in my country lacks protection for the cast aluminum parts of the cooling system, lacks protection for the solder in the cooling system, and the pitting corrosion of the engine cooling system by the engine coolant has always been a problem. If it is not solved, many tentative solutions are not effective. The effect of pitting corrosion prevention and control by using ternary polycarboxylic acid coolant alone cannot meet the ideal requirements and cannot meet the needs of many occasions.
