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 crystallization; glycerin has high viscosity, poor antifreeze, and is incompatible with rubber; Ethylene glycol has high viscosity at low temperature, poor antirust ability, etc., and many existing coolants have poor antifreeze ability

Embodiment Construction

[0012] An antifreeze coolant, made of the following components in parts by weight, 150 parts of propylene glycol and ethylene glycol blend, 15 parts of potassium citrate, 10 parts of simethicone, 2 parts of sorbitol, 6 parts of boric acid, borax 5 parts, 8 parts of pentaerythritol, 12 parts of glycerin.

[0013] Further, the blend of propylene glycol and ethylene glycol is propylene glycol and ethylene glycol mixed at a ratio of 1:3 at 35-40°C, and then uniformly stirred for 30 minutes at a stirring speed of 300 r / min.

[0014] Further, the borax is pretreated: the borax is first treated at a constant temperature of 400°C for 30 minutes, and then put into a 300MHZ microwave for 40 minutes for calcining.

[0015] Further, the simethicone is pretreated: a mixture of 1.5 parts by weight of oligoethylene glycol methyl glycidyl ether and octamethylcyclotetrasiloxane is mixed with simethicone, The temperature is 55°C, and the reaction is carried out for 3-4 hours; the polyethylene ...

Abstract

The invention discloses antifreezing cooling liquid. The antifreezing cooling liquid is prepared from a propylene glycol and ethanediol blend, sodium citrate, simethicone, sorbitol, boric acid, borax, pentaerythritol and glycerol. The cooling liquid is good in cooling performance, the ice point of the cooling liquid is controlled to range from -40 DEG C to -55 DEG C, the boiling point is controlled to range from 145 DEG C to 150 DEG C, the needs of most occasions are met, the problem that cold starting is possibly hard in cold weather is thoroughly solved, and the antifreezing function is good.

Description

technical field [0001] The invention relates to the technical field of cooling liquid, in particular to an antifreeze 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, poor antirust ability, etc., and many existing coolants have poor antifreeze ability. Contents of the invention [0003] The purpose of the present invention is to provide a kind of antifreeze coolant. [0004] The present invention is realized through the foll...
