Abstract
The invention aims at providing a novel automotive anti-freeze fluid. The novel automotive anti-freeze fluid is prepared from the following components: water, glycerin, a corrosion inhibitor, potassium permanganate, an antioxidant, a corrosion and scale inhibitor and an antifoaming agent at the weight percent ratio of 100 to (90-150) to (0.05-0.25) to (0.1-0.4) to (0.2-0.45) to (0.2-1.2) to (1.0-1.5). The novel automotive anti-freeze fluid has the effects of being high in stability, not easy to volatilize, high in anti-freeze property, anti-rust property and fouling resistance, and does not block a pipeline.
Description
Technical field
The present invention is specifically related to a kind of deicing fluid of motor car engine, belongs to chemicals field.
Background of invention
The research of the deicing fluid such as motor car engine, has the history of more than 70 year so far from the thirties, and so far the method for various countries to preparation deicing fluid is still among research at present.Automobile antifreeze solution is generally take alcohols as main component, auxiliary with related auxiliaries, formulated, it is the liquid that a kind of freezing point is lower, can not freeze at low temperatures, there is good mobility, heats a large amount of in engine operation process can be taken away thus ensure engine can low temperature environment normal operation, the composition of current deicing fluid is mainly with methyl alcohol, ethanol and glycerol and calcium chloride are main, but found that with methyl alcohol and ethanol time boiling point and flash-point all too low, volatile, lose larger, thermostability and antifreeze energy are also poor, and calcium chloride easily precipitates.Therefore, choose the preparation that suitable frostproofer carries out deicing fluid more and more to receive publicity.
The present invention is different from other deicing fluid, and with glycerol, water, corrosion inhibitor, antioxidant, anti-incrustation corrosion inhibitor and defoamer composition, antifreezing effect is good.
Summary of the invention
The object of the present invention is to provide a kind of deicing fluid of motor car engine.
In order to achieve the above object, this invention takes following technical scheme:
Technical scheme of the present invention is as follows:
A kind of preparation relating to automobile antifreezing liquid system, it is characterized in that: be made up of glycerol, water, corrosion inhibitor, antioxidant, anti-incrustation corrosion inhibitor and defoamer, made the corresponding automobile engine winterization fluid that can obtain the present invention relates to by the above main ingredient through specialized processes.Wherein:
Described water is preferably from least one in distilled water, deionized water, pure water.
Described glycerol is 1,2-glycerol or 1,3-glycerol.
Described corrosion inhibitor is preferably mercaptobenzothiazole.
Described antioxidant preferably from: one of butylated hydroxytoluene, Tenox PG, Resorcinol, p-ten.-butylcatechol or combination.
Described anti-incrustation corrosion inhibitor is preferably from organic phosphates: one of carboxyl ethylene phosphoric acid, aminotrimethylene phosphoric acid or combination.
Defoamer preferably from: defoamer preferably from one of polyether-modified silicon, organo-siloxane, polyethers or combination.
In formula, the weight ratio of each component is as follows: water: glycerol: corrosion inhibitor: potassium permanganate: antioxidant: anti-incrustation corrosion inhibitor: defoamer is 100:(90-150): (0.05-0.25): (0.1-0.4): (0.2-0.45): (0.2-1.2): (1.0-1.5)
Advantage of the present invention and effect are: stability is high, not volatile, not blocking pipe, and antifreeze, antirust, ant-scaling high.
