The battery raw materials such as diaphragm, electrolyte influence other than its performance, and temperature change in new-energy automobile driving process etc. can also change
Become battery performance, and then influences its cruising ability.Suitable temperature is only kept, battery can be only achieved its optimum performance.In addition,
The short circuit of battery and overcurrent also result in battery catches fire, to cause accident.The present invention is intended to provide a kind of dissipate with excellent
The high security new energy car battery of hot property and anti-short circuit, anti-overflow.
Summary of the invention
It is an object of the invention to solve above-mentioned shortcoming and defect existing in the prior art, it is new to provide a kind of high security
Energy automobile battery.
To reach its purpose, the technical solution adopted by the present invention are as follows: a kind of high security new energy car battery comprising
Heat-dissipating casing, bus, battery modules and Embedding Material in the heat-dissipating casing；The battery modules are by several batteries
Composition, the positive and negative anodes of the battery are connect with the bus, and the Embedding Material is filled in the heat-dissipating casing and separates packet
The battery is covered, the interface connecting with the bus is additionally provided on the heat-dissipating casing；

Dual-tert-butyl peroxy isopropyl base benzene belongs to high-temperature peroxide vulcanizing agent.The present invention uses the higher dual-tert-butyl mistake of decomposition temperature
Oxygen cumene compounds the lower dibenzoyl peroxide of decomposition temperature, when so that preparing Embedding Material, plays the shortening of sulphur time, just
Vulcanization time extends, so that the concentration of dynamic vulcanization stage peroxide radical is relatively stable, the viscosity of material will not increase severely,
And be easy mixing and be uniformly dispersed, to effectively improve the mechanical property of material.
Preferably, based on mass percentage, the peroxide vulcanizing agent by 25% dibenzoyl peroxide and
75% dual-tert-butyl peroxy isopropyl base benzene composition.
Preferably, the plasticizer is dibutyl phthalate (DBP).The DBP belongs to external plasticizer, is not involved in
Reaction, but the reduced gravity of molecule interchain can be made, to increase the movement and flexibility of strand, keep Embedding Material encapsulating solid
Brittleness after change correspondingly reduces, and flexibility and plasticity are improved.
Preferably, the modified aluminas is hexadecyl trimethoxy silane modified aluminas.The cetyl three
Influence of the methoxy silane modified aluminas to the viscosity of Embedding Material is smaller, and can effectively improve the thermal conductivity of Embedding Material
Can, to improve the radiating efficiency of new-energy automobile power battery, improve its safety.
Preferably, the modified aluminas the preparation method comprises the following steps: aluminium oxide is put into electric heating constant-temperature blowing drying box,
Dry 3h, is subsequently poured into high-speed mixer, by the mixing of hexadecyl trimethoxy silane isopropanol and toluene at 105 DEG C
