Abstract
The invention relates to the technical field of chemical materials, in particular to an engine non-aqueous coolant composition. The composition is prepared from, by weight, 3-12 parts of ethylene glycol, 3-10 parts of propylene glycol, 6-10 parts of diethylene glycol, 3-10 parts of cosolvent, 7-15 parts of hydroxyl aromatic acid, 6-10 parts of citrate, 55-70 parts of sorbitol, 2-7 parts of silicate ester, 1-5 parts of tolyl triazole and 25-44 parts of water. The invention is aimed at providing coolant which is high in boiling point, low in freezing point, high in flashing point and low in viscosity.
Description
Technical field
The present invention relates to the technical field of chemical materials, specifically a kind of electromotor Non-water-cooled
But liquid compositions.
Background technology
Temperature in the manufacturer of some large-scale apparatuses is that comparison is high, this is because these works
There is substantial amounts of heavy-duty machines in factory, and during the running of these heavy-duty machines, electromotor will produce substantial amounts of heat
Amount so that the temperature in factory raises.So, we can use coolant to cool down electromotor,
Its temperature is made to be minimized.If but engine temperature drops too low, some necessary heats also can
Run off therewith, such electromotor cannot normal operation, the manufacturing schedule of Tuo Man factory.
Non-aqueous coolant for engine compositions, as coolant, serves not only as automobile, train, flies
The coolant of the electromotor such as machine, boats and ships, also has the multiple merits such as anti-boiling, anticorrosion, antiscale
Energy.Electromotor is to high-power, heavy load, the development of high rotating speed, and volume the most progressively diminishes, and starts
The operating temperature of machine improves constantly, accordingly, it would be desirable to a kind of boiling point is more than 150 DEG C, heat transfer
Effective coolant.
At present, water-free cooling is mainly liquid add multiple corrosion inhibition based on propylene glycol
The compositions that agent obtains.Engine coolant high boiling point, low freezing point, high sudden strain of a muscle cannot be solved simultaneously
Point, low viscous requirement.
Summary of the invention
It is an object of the invention to provide a kind of high boiling point, low freezing point, high-flash, low viscous want
The coolant asked.
The present invention, by the optimal screening to antifreezing agent and matrix components, determines between each component
Good ratio so that coolant freezing point controls between 30～50 DEG C, boiling point control is at 130～150 DEG C
Between, while ensureing engine work performance, also improve the fuel oil effect of electromotor
Rate, thus save oil consumption and disposal of pollutants.In controlling coolant antiseptic property, by having
Machine acid and the buffer system of salt composition thereof, the pH stable of permanently effective control coolant exists
Between 7.5～9.5, prevent cooling system from producing burn into spot corrosion, precipitation and water pump leakage and make
It has the anti-rotten characteristic of the most advanced active.
The technical solution used in the present invention is:
A kind of non-aqueous coolant for engine compositions, described component component by weight divides: ethylene glycol
3-12 part, propylene glycol 3-10 part, diethylene glycol 6-10 part, cosolvent 3-10 part, hydroxyl virtue
Fragrant acid 7-15 part, citrate 6-10 part, sorbitol 55-70 part, esters of silicon acis 2-7 part,
4-methyl 1H-benzotriazole 1-5 part, water 25-44 part.
Preferably, described component component by weight divides: ethylene glycol 7.5 parts, propylene glycol 6.5 parts,
Diethylene glycol 8 parts, cosolvent 6.5 parts, hydroxy aromatic acid 11 parts, citrate 8 parts, mountain
Pears alcohol 62.5 parts, esters of silicon acis 4.5 parts, 4-methyl 1H-benzotriazole 3 parts, 34.5 parts of water.
The method have the advantages that high boiling point, low freezing point, high-flash, low viscosity.
Detailed description of the invention
Below embodiments of the invention are described in detail, so that advantages and features of the invention
Can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made more
