Abstract
An antifreezing liquid with antifreezing, antiiceing, antirust, antiscaling and scale-removing functions for car features the additional use of the triethanolamine for removing scale and the in creasement in the dosage of benzotriazole for preventing eduction of scales and improving the anticorrosion effect.
Description
Technical field:
Belong to automobile deicing fluid goods of the present invention, specially refer to a kind of prescription and preparation method of automobile freeze-proof liquid.
Background technology:
The car owning amount of China rises year by year at present, the automobile usage quantity in especially northern frigid zone also heightens, every winter, the usage quantity of automobile antifreeze solution was very big, this just need have a variety of new prescriptions to occur at the automobile antifreeze solution goods, we know that the cooling system of vehicle mostly adopts water as heat exchange medium, because after water freezes at low temperatures, volume increases 9%, if do not bleed off the water of cooling system after winter, vehicle travelled, will be because of the spalling cooling system that freezes, and long-term water is cooked exchang medium, can make the parts of metal be subjected to corrosion and structure influence heat exchange, shorten the life-span of engine, therefore deicing fluid not only needs good cooling performance, the function that anti-freeze and antirust antiscale are arranged again, rust-preventive agent in the market satisfies these needs substantially, but it is all on the high side, the present invention wants to make a kind of not only low cost but also can be antifreeze, anti-freeze and antirust, the automobile antifreeze solution of antiscale and detergency, major advantage of the present invention is the descaling function that has increased trolamine, it has automatic generation scavenging(action) to the dirt that whole automobile produces when not using deicing fluid.Reduce the cost of deicing fluid, will increase the usage quantity of chloride tap water, so the present invention has increased consumption on the use benzotriazole, and the maximum effect of this material is to improve deicing fluid and intermetallic heat conduction velocity, and can slow down separating out and the decline of pH value of rust deposite, and benzotriazole has good preservative activity, the only adjustable 1-2 of general deicing fluid tap water doubly.The adjustable 1-4 of the present invention tap water doubly, and can use 50,000 kilometers at subzero 30 degree travels and will clean cooling system after 50,000 kilometers, and more renews deicing fluid.
Technical scheme is as follows:
Main raw of the present invention has adopted the main raw material ethylene glycol that can reduce freezing point, the borax of antirust, anti-enzyme, and Sodium Nitrite, saltpetre, trolamine etc., and increased the consumption of benzotriazole, also have trinitrophenol, and increased the consumption of benzotriazole.
Ethylene glycol 94.15% trolamine 0.2%
Borax 3% benzotriazole 0.8%
Trinitrophenol 0.15% sodium hydroxide 0.3%
Saltpetre 0.25%
Sodium Nitrite 0.15%
Water glass 1%
Specific embodiments: the automobile antifreeze solution of preparation 1000 grams
At first trinitrophenol is used the hot water dissolving, then 30 gram boraxs, 10 gram water glass are mixed evenly, again 0.25 the gram saltpetre, 0.15 the gram Sodium Nitrite pour into 940.15 the gram ethylene glycol in stir after, again all materials that are mixed are stirred in together, be dissolved in the ethylene glycol, all material dissolving evenly back product is promptly finished.The present invention can be fit to all car engine cooling systems, also is applicable to the preventing freeze in winter of engine generator set.
Increased the content of benzotriazole among the present invention than general deicing fluid, deicing fluid and intermetallic heat conduction velocity have been improved, and our present tap water chlorinity is all very high, increased the ratio of benzotriazole in the deicing fluid, make deicing fluid in use, can add tap water than 2 times of conventional deicing fluid as many as.When deicing fluid of the present invention and water use by 1: 1 mixed, to make freezing point reduce to subzero 36.7 degree, if by under the zero temperature in the minimum temperature Three Eastern Provinces in our north 25 to subzero 30 degree, can make the add-on to 1 of water: 3, if in Beijing, the words of subzero 15 degree of ground minimum temperatures such as Tianjin, Hebei, Shanxi, deicing fluid of the present invention was added to 1: 3 to 1: 5, the strong point of automobile freeze-proof liquid of the present invention like this is just therewith, and scale removal ability of the present invention in addition is greater than present popular deicing fluid.
Claims (2)
1, a kind of prescription of automobile freeze-proof liquid and preparation method have increased the content of benzotriazole and water glass in it is characterized in that filling a prescription, it is as follows to fill a prescription:
Ethylene glycol 94.15% trolamine 0.2%
Borax 3% benzotriazole 0.8%
Trinitrophenol 0.15% sodium hydroxide 0.3%
Saltpetre 0.25%
Sodium Nitrite 0.15%
Water glass 1%
2, the prescription of a kind of automobile freeze-proof liquid according to claim 1 and preparation method, the benzotriazole among the present invention and the employing of water glass and increase consumption make deicing fluid of the present invention increase the function of deicing fluid, be to reduce market value of the present invention, and increase scale removal, the dirt that disappears, antirust main key.
