Technical field
The invention belongs to silastic material field more particularly to a kind of lithium battery encapsulating silicon rubber.
Background technique
Vehicle lithium battery material has numerous electronic components, high-power circuit module, large-scale integrated circuit board etc. multiple
Miscellaneous electrical component, said elements needs are filled closing, with fixation component therein, protect it from environment influence.Electrically
The filling of element is closed common casting glue and is carried out, the casting glue used need to have good insulation performance, lower water absorption rate,
Preferable absorbing and securely and the performances such as component are not corroded to the bonding of electronic component and plate, with vehicle lithium electricity
The increase of pond group energy density and the wherein raising of electronic component power, it is also higher and higher for the requirement of casting glue at present,
Casting glue material is not required nothing more than with excellent high voltage withstanding, thermally conductive and flame retardant property, but also requires its viscosity lower, with benefit
In the micro gap poured into electronic component.
Encapsulating glue material main component currently used for electronic product protection is mostly dual composition addition type silicon rubber, and first group
Divide is mostly containing vinyl polysiloxane (also known as vinyl silicone oil), filler and crosslinking agent hydrogen-based polysiloxanes (also known as Silicon Containing Hydrogen
Oil) mixture, the second component be mostly the mixture containing vinyl silicone oil, filler and catalyst, above two component is mixed
After conjunction, elastomer-forming can be solidified at ambient temperature or elevated temperature, that is, can reach the purpose of protection electronic component.
The document according to disclosed in the prior art in dual composition addition type silicon rubber it is found that add more thermally conductive and resistance
The better thermally conductive and flame retardant property of the silicon rubber that combustion filler can assign, still, the increase of filler quantity will lead to ethylene
The viscosity and density of the mixture of base silicone oil and filler increase rapidly, when filler is added to it is a certain amount of when, the flowing of sizing
Property can be very poor, can not as electronic component protect casting glue come using moreover, because inevitably containing in polysiloxanes
A certain amount of low molecule volatile substances, so that obtained casting glue product is during cured because of soluble matter volatilization and liquid
Solidify and generate certain contraction, stress may be generated when shrinking percentage is excessive, so that part electronic component floats
