Abstract
The present invention provides a kind of electrokinetic cell low volatilization, low viscosity heat conduction silicone oil and preparation method thereof, is mixed in proportion and is made by phenyl methyl silicone oil, ionic liquid and cerium sesquioxide.The particular viscosity that the present invention has using phenyl methyl silicone oil, to meet the viscosity, volatility and the heat-resisting ageing-resisting performance that use, while specific ionic liquid is added, while system thermal conductivity is improved, further reduce the volatile performance of system.
Description
Technical field
The present invention provides a kind of electrokinetic cell low volatilization, low viscosity heat conduction silicone oil and preparation method thereof, is keeping original
On the basis of the premium properties of silicone oil, silicone oil volatility in applied at elevated temperature is considerably reduced, improves its temperature classification, belonged to
In coolant preparing technical field.
Background technology
Silicone oil is a kind of with various different viscosities, nontoxic, odorless, corrosion-free, nonflammable polyorganosiloxane fluid oil
Shape thing.For heat-conducting medium, methyl phenyl silicone oil purposes than wide, but some application scenarios for example electric automobile electricity
In the group cooling system of pond, volatility tends not to meet requirement simultaneously with viscosity.Low volatilization is opposite a pair with low viscosity
Index, because for oils, its molecular weight is smaller, and viscosity is with regard to smaller, but volatility is higher, opposite molecular weight
Higher, viscosity is higher, and volatility is lower,
In addition, the thermal conductivity of silicone oil can increase when starting with the raising of silicone molecule amount, and when its viscosity increases to
After certain content, the thermal conductivity of silicone oil is almost just a definite value, is a quarter of water or so under normal circumstances, if wanting to increase
Add its thermal conductivity, be essentially that can not add general heat filling：Because heat filling used is typically inorganic particle,
This can cause the increase of silicon oil viscosity, and the deterioration of silicone oil bin stability；And the liquid fused salt harmless to battery should be added（From
Sub- liquid）Solve.
The content of the invention：
The present invention provides a kind of electrokinetic cell low volatilization, low viscosity heat conduction silicone oil, to meet the viscosity of system, volatility
And heat-resisting ageing-resisting performance, while specific ionic liquid is added in right amount, while system thermal conductivity is improved, further drop
The volatile performance of low system.
Invention further provides a kind of electrokinetic cell low volatilization, the preparation method of low viscosity heat conduction silicone oil, it is applicable
In industrialized production.
A kind of electrokinetic cell of the present invention with it is low volatilization, low viscosity heat conduction silicone oil, be by following raw material by weight
Made of number ratio：
Phenyl methyl silicone oil（Molecular weight is 2000-3000）100 parts, ionic liquid 1-10 parts：2 parts of cerium sesquioxide.
Described ionic liquid is：1- butyl -3- methylimidazole titanium tetrachloride salt or the chlorination of 1- hexyl -3- methylimidazoles four
Molysite；Structural formula is as follows：
1- butyl -3- methylimidazole titanium tetrachloride salt 1- hexyl -3- methylimidazole titanium tetrachloride salt
The present invention provides a kind of electrokinetic cell low volatilization, low viscosity heat conduction silicone oil building-up process, comprises the following steps：
Above-mentioned raw materials are weighed in proportion, it is well mixed to produce.
The positive effect of the present invention is：The particular viscosity having using phenyl methyl silicone oil, to meet that the present invention uses
Viscosity, volatility and heat-resisting ageing-resisting performance, while add specific ionic liquid, improving the same of system thermal conductivity
When, the further volatile performance for reducing system.Compared with existing product, while having compared with low viscosity, also waved with relatively low
Hair property.
