Abstract

The invention relates to a cooling liquid. The cooling liquid is prepared from the following components in parts by weight: 160 parts of a blend of propylene glycol and ethylene glycol, 3 parts of potassium citrate, 10 parts of sodium silicate, 8 parts of dimethyl silicone oil, 8 parts of a mixture of formic acid and acetic acid, 4 parts of starch, 3 parts of montmorillonite nano-particles and 12parts of glycerinum. The cooling liquid provide by the invention has the following advantages that the comprehensive performance of all aspects of the cooling liquid is improved, the cooling performance is good, the anti-freezing effect is good, and the cooling liquid is not corrosive, and does not pollute the cooling pipelines.

Description

technical field [0001] The invention relates to the technical field of cooling liquid, in particular to a cooling liquid. 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 viscosity at low temperature and poor anti-rust ability, etc., and the life of general engine coolant is short, frequent replacement, and high cost of use. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a cooling liquid with good cooling performance ...
