Abstract
The invention provides a low-volatility and low-viscosity heat conduction silicone oil for power cells, and a preparation method thereof. The low-volatility and low-viscosity heat conduction silicone oil is prepared through uniformly mixing phenyl methyl silicone oil, an ionic liquid and dicerium trioxide in proportion. The specific viscosity of the phenyl methyl silicone oil is used to meet use viscosity, volatility and heat and ageing resistance, and the specific ionic liquid is added to improve the heat conductivity of a system and further reduce the volatility of the system.
Description
Technical field
The invention provides the low volatilization of a kind of power cell, low viscosity heat conduction silicone oil and preparation method thereof, on the basis of premium properties keeping original silicone oil, considerably reduce silicone oil volatility when applied at elevated temperature, improve its temperature classification, belong to cooling fluid preparing technical field.
Background technology
Silicone oil is that a class has various different viscosity, nontoxic, odorless, corrosion-free, nonflammable polyorganosiloxane fluid oily matter.As heat-conducting medium, methyl phenyl silicone oil purposes is relatively more extensive, but in some application scenario such as batteries of electric automobile group cooling system, volatility and viscosity often can not meet service requirements simultaneously.Low volatilization and low viscosity are a pair phase inverse indicators, this is because for oils, its molecular weight is less, and viscosity is less, but volatility is higher, and contrary molecular weight is higher, and viscosity is higher, and volatility is lower,
In addition, can increase along with the raising of silicone molecule amount when the thermal conductivity of silicone oil starts, and after its viscosity is increased to certain content, it is a definite value that the thermal conductivity of silicone oil is just close to, and is about 1/4th of water under normal circumstances, increases its thermal conductivity if want, to add general heat conductive filler in principle: because, heat conductive filler used normally inorganic powder, this can cause the increase of silicon oil viscosity, and the deterioration of silicone oil package stability; And the liquid fused salt (ionic liquid) harmless to battery should be added solve.
summary of the invention:
The invention provides the low volatilization of a kind of power cell, low viscosity heat conduction silicone oil, to meet the viscosity of system, volatility and heat-resisting ageing-resisting performance, the specific ionic liquid of appropriate interpolation simultaneously, while raising system thermal conductivity, the volatile performance of further reduction system.
