Abstract

The invention discloses a glycerin containing anti-freezing solution and relates to the field of automobile anti-freezing solutions. The glycerin containing anti-freezing solution is prepared by mixing a glycerin containing solution A with a mixed solution B taking water as the main component; the anti-freezing solution does not contain ethylene glycol; the solution A accounts for 1-99% of totalweight of the anti-freezing solution; the mixed solution A is prepared from water, dicarboxylic acid, a metal hydroxide aqueous solution and one or more substances of triazole, chelating agent, saturated fatty acid and unsaturated fatty acid. With a freezing point of -20 DEG C, the anti-freezing solution disclosed by the invention is not solidified when cooled to -20 DEG C or lower temperature, and thus has a good anti-freezing effect at low temperature.

Description

technical field [0001] The invention belongs to the field of automobile antifreeze, in particular to an antifreeze containing glycerin. Background technique [0002] Automobile antifreeze, also known as "antifreeze" or "antifreeze", the full name should be called automobile antifreeze coolant, which means coolant with antifreeze function, so that the car can continue to be used at low temperatures in winter. Engine coolant will add some substances that can lower the freezing point of water as antifreeze to keep the cooling system from freezing in low temperature weather. [0003] Especially in the northern region, the quality of the antifreeze determines the service life of mechanical equipment to a large extent. The current antifreeze will fail when it is used for a long time. Contents of the invention [0004] The object of the present invention is to provide an antifreeze solution containing glycerin, which has a freezing point of -20°C, and will not solidify even if t...
