Novel long-acting coolant

Abstract

The invention discloses a novel long-acting coolant which is prepared from the following raw materials in parts by weight: 25-50 parts of ethylene glycol, 10-15 parts of sorbitol, 5-10 parts of ammonium phosphomolybdate, 3-6 parts of tetramethyl orthosilicate, 2-6 parts of decanedioic acid, 3-7 parts of octanoic acid, 4-8 parts of sodium citrate, 3-5 parts of castor oil triethanolamine, 7-10 parts of sodium nitrate, 1-8 parts of sodium nitrate, 2-7 parts of polyvinyl alcohol, 3-7 parts of tall oil, 4-7 parts of molybdate, 4-8 parts of organosilicate, 1-5 parts of succinic acid, 2-6 parts of undecanoic acid and 3-7 parts of sodium benzoate. The novel long-acting coolant has the advantages of reasonable formula, high corrosion resistance and favorable storage stability.

Description

technical field

[0001] The invention relates to the technical field of cooling liquid, in particular to a novel long-acting cooling liquid. Background technique

[0002] Coolant is a complex multi-component system, mainly composed of antifreeze, corrosion inhibitor, defoamer, colorant, antifungal agent and buffer. An excellent coolant should have the functions of heat dissipation, anti-corrosion, anti-freezing, high boiling point, anti-scaling and anti-foaming. Antifreeze as an engine coolant has undergone changes from methanol, ethanol, water, salt water, to glycerin, diethylene glycol, and then to ethylene glycol. With the improvement of people's understanding and the development of 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 a high viscosity , poor antifreeze, incompatible...
