Background technology
With the raising of engine power, the continuous diminution of volume, the stringent control of discharge, thermic load and relevant reliable
Sex chromosome mosaicism is more and more prominent, and the importance of cooling system is growing day by day.
Engine coolant is mainly made of water, ethylene glycol and additive, and two additives are based on corrosion inhibitor, addition
The effect of agent is mainly anti-corrosion, while has effect of the antiscale with anti-bubble concurrently, and the basal liquid of current most coolant is substantially
It is ethylene glycol, the difference of different formulations mainly employs different corrosion inhibition systems.Major part currently on the market is cold
But liquid product employs siliceous or organic acid type for corrosive agent, this kind of product substantially has advantage and disadvantage, especially right
For system of Japan and Korea S automobile, generally using the coolant of phosphorous system, with gradually increasing, it is necessary to research and develop for system of Japan and Korea S vehicle
Go out more excellent performance of phosphorous cooling liquid product, since traditional phosphate can reduce the protective effect to aluminium at high temperature,
Floccule precipitation can be also combined to form with the calcium ions and magnesium ions in hard water, blocks heat dissipation device coil pipe, causes coolant flow not smooth, production
Raw overheat, it is therefore desirable to the shortcomings that improving phosphorous formula, to adapt to the needs of Modern Engine.
The content of the invention
Phosphorous engine coolant provided by the invention, has the corrosion inhibition of excellent aluminium and scolding tin metal, has at the same time
There are good hard water compatibility and preferable nonmetallic materials compatibility.
Specifically, phosphorous engine coolant provided by the invention is made of the component of following percentage by weight：
As a preferred embodiment, the phosphorous engine coolant is made of the component of following percentage by weight：
As a preferred embodiment, the phosphorous engine coolant is made of the component of following percentage by weight：
Parts by weight of the present invention can be the unit of weight well known in the art such as mg, g, kg or its multiple, such as

The antisludging agent is ethylene diamine tetra methylene phosphonic acid or ethylenediamine tetramethylene phosphonic acid.The antisludging agent has very strong
Chelated metal ions ability, in coolant use can also ensure the stability of solution.
The buffer is 3- hydroxyls -3- carboxyls glutaric acid or 2- hydroxysuccinic acids.It is soluble easily in water, to human body and environment
Harmless, used with phosphoric acid class corrosion inhibiter has more excellent cushioning effect in the solution.
The defoamer is PE6100.
The alkaline pH adjuster is preferably NaOH, can effectively adjust the acid-base value of solvent, it is ensured that coolant is produced
The excellent corrosion inhibition for metal performance of the stability agent of product.
The organic solvent is preferably ethylene glycol.It is a discovery of the invention that by 2- hydroxyphosphonoacetic acid or hydroxy ethylene two
Phosphonic acids is in the aqueous solution of ethylene glycol using engine cool liquor and rubber can be made to have preferable compatibility.
The water preferably uses deionized water.
On the basis of the selection to each component optimizes, the present invention preferably phosphorous engine coolant is by as follows
The component composition of percentage by weight：
Further preferably it is made of the component of following percentage by weight：
Or it is made of the component of following percentage by weight：
As the preferred solution of the present invention, the phosphorous engine coolant is made of the component of following percentage by weight：
By largely putting into practice discovery, the phosphorous engine coolant being formulated using above-mentioned preferred solution is had the present invention
Extremely excellent aluminium corrosion inhibition and hard water compatibility performance, has extremely strong application value.
In actual application, coloring agent additionally can be added in phosphorous engine coolant provided by the invention, contaminated
The color and dosage of toner can be added according to needs.
Phosphorous engine coolant provided by the invention can be prepared according to this area conventional method.As the preferred of the present invention
Scheme, can use following steps：It will contain phosphor corrosion inhibitor, antisludging agent, buffer, organic solvent and pH adjusting agent according to proportioning to be dissolved in
In water, stirring at normal temperature 30~60 minutes, adds defoamer, stirs 15~20 minutes, you can.
, can be with the following method when additionally adding coloring agent in phosphorous engine coolant：According to the method described above
Coloring agent is directly added into the phosphorous engine coolant being prepared, is stirred 10-15 minutes.Since defoamer is finally
Disperse in the solution, therefore, it is necessary to which first stirring evenly makes to add coloring agent after defoamer is fully dispersed, ensure that coloring agent exists
Also uniform state is presented in solution.
Phosphorous engine coolant provided by the invention is applied to engine, is preferably applied to automobile engine.
