Description
The present invention relates to a kind of boiling-preventing antifreezer that engine cooling water adds that is used for.
The development of automobile antifreeze solution " four unifications ' " by comrade Yang Junzhu work that " Shaanxi chemical industry " nineteen ninety-five the 1st periodical carries, this automobile antifreeze solution mainly selects for use ethylene glycol as main raw material, can reduce the freezing point of water because of ethylene glycol; Selected for use tripoly phosphate sodium STPP to make the scale remover component; Select for use Sodium Benzoate as the sanitas in the deicing fluid; Select for use borax, water glass, trolamine as rust-preventive agent; Select for use benzotriazole in deicing fluid, to use and be to improve deicing fluid and intermetallic heat conduction velocity, slow down separating out and pH value being descended of dirt, while tool preservative activity.The weak point of this deicing fluid is there is not anti-flaming function, and because of ethylene glycol is inflammable substance, the refrigerating fulid that does not have an anti-flaming function is accident potential under cover in use; The freezing point of this deicing fluid is only regulated by the ratio of ethylene glycol and water, minimumly can only reach-49 ℃, and freezing point is low not enough; This deicing fluid does not have the high boiling point performance, is confined to use winter." chemical goods scientific and technological information " be " research of automobile long-life coolant " in the first phase, is collaborateed by Jinling Petrochemical Co.'s chemical industry one Jiang Hua of institute of factory and the Wang Wen of equipment research institute of Jinling Petrochemical Co. swallow, to the still last narration that relates to anti-flaming function of deicing fluid." the military deicing fluid of the U.S. " in enumerating three prescriptions of deicing fluid wherein has the ethylene glycol monomethyl ether component, and molecular formula is C
3H
3O
2, therefore, the military deicing fluid boiling point of the U.S. also can not be high, also can only use winter; The water that uses in the prescription of the military deicing fluid of the U.S. is not done special processing yet, the electric conductivity height.By the patent of invention of Bo Da Science and Technical Development Company application, " deicing fluid and production method thereof ", application number: 88106561.7, mention in this patent application, the deicing fluid of alcohol-water type is prevented the freezing point height, and it is dangerous easily to catch fire, but does not solve fire-retardant problem in its technical scheme; Employed water in this technical scheme is ortho-water, can cause the electric conductivity height of refrigerating fulid; This technical scheme has solved general antifreeze, requirement for anticorrosion, other function such as high boiling point, does not fire-retardantly possess.
The objective of the invention is provides a kind of non-corrosive antisludging fireproof boiling-preventing antifreezer and preparation method thereof in order to overcome above-mentioned weak point, have not only that common freezing point is low, anticorrosion, scale inhibition function, also have high boiling point, anti-flaming function, owing to increased anti-flaming function, made easily ignitable deicing fluid in use compare safety; Because the boiling point height, can reach 110 ℃-150 ℃, not only can preventing freeze in winter, also can use summer to prevent boiling; Owing to improve prescription, make the deicing fluid freezing point lower ,-60 ℃～-70 ℃; Employed water in the present invention prescription be the deionized water through handling, thereby electric conductivity is low, in the time of 30 ℃ less than 110 μ S/cm.
Description of the present invention is as follows, and non-corrosive antisludging fireproof boiling-preventing antifreezer is main raw material with ethylene glycol still, and employed water is deionized water.Select for use dioctyl azelate, diethylene glycol monomethyl ether to reduce the freezing point of engine cooling water, improve the boiling point of water coolant, winter, summer all can use.Make fire retardant with primary ammonium phosphate, potassium hypophosphite, sodium phosphite three components, make Scale inhibitors with tripoly phosphate sodium STPP, potassium polyphosphate, acrylate three components.
The making method of non-corrosive antisludging fireproof boiling-preventing antifreezer: carry out earlier the preparation of Scale inhibitors, fire retardant respectively, after carry out the finished product preparation.The preparation of Scale inhibitors: by weight, the tripoly phosphate sodium STPP with 1～2%, 2～3% potassium polyphosphate, 0.5～7% acrylate add 88～96.5% the deionized water for stirring that has been heated to 60 ℃ respectively, are incubated after 30 minutes, are cooled to normal temperature.The preparation of fire retardant: by weight, primary ammonium phosphate with 1～2%, 1～2% potassium hypophosphite, 1～3% sodium phosphite add respectively in 93～97% the deionized water that has been heated to 50 ℃, be heated with stirring to boiling, be incubated 20 minutes, be cooled to normal temperature again.The preparation of finished product: by weight, ethylene glycol accounts for 30～60%, in ethylene glycol, add 10～50% deionized water, 1～10% dioctyl azelate, 1～10% diethylene glycol monomethyl ether respectively, stir, be heated to 110～130 ℃, and be incubated 30 minutes, be cooled to normal temperature, add 10～20% Scale inhibitors and 5～15% fire retardant more respectively, stir, form product.
In the non-corrosive antisludging fireproof boiling-preventing antifreezer finished product, by weight, the shared per-cent of each moiety is:
Deionized water 30～65.5%
