This is not considered as limiting the invention.
Embodiment 1.
Referring to Fig. 1-2.
Present embodiments provide a kind of electric vehicle battery holder, including box cover 1, box body 2, battery pack 3 and accessory part 4.
Battery pack 3 and accessory part 4 are arranged in box body 2, and box cover 1 covers the opening in box body 2, battery pack 3 with it is auxiliary
Help the electrical connection of component 4 with realizations battery pack 3 charge and discharge, box body 2 includes the front side wall and rear wall that are oppositely arranged, battery pack
3 are extruded on front side wall, and accessory part 4 is extruded on rear wall, there are gap between accessory part 4 and box cover 1, fill out in gap
Filled with buffering insulating materials.
Buffer the ingredient of insulating materials according to the mass fraction:
Linear low density polyethylene, density 0.92g/cm3, 50 parts;
Polyethylene glycol, molecular weight 800-1000,30 parts;
Polypropylene, 10 parts;
Tricresyl phosphate, 10 parts.
Take linear low density polyethylene compared with low-density as buffering insulating materials main body on the one hand can as far as possible with
Lower mass charge expires gap, on the other hand has good specific heat coefficient and thermal stability, can reduce electricity as far as possible
The raising of temperature in the use process of pond.The branch of linear low density polyethylene is less, so that buffering body of dielectric material shape
Change ability is preferable, can effectively fill into gap in irregular shape, play the full protection to battery.Furthermore it is certain right to have
The linear low density polyethylene of title can also play the role of diamagnetic, certain to battery progress diamagnetic protection.Polyethylene glycol is then made
For solvent, so that linear low density polyethylene forms the state with certain stickiness.The polyethylene glycol one of molecular weight 800-1000
Aspect makes buffering insulating materials have certain fluid property, is easy voluntarily to fill to tiny gap, while can show
Enough hydrophobicitys out.And polyethylene glycol is easy to form hydrogen bond with linear low density polyethylene, is able to ascend buffering insulating materials
Internal intermolecular spacing advantageously reduces the density inside buffering insulating materials.
Polypropylene itself has good insulating properties, is able to carry out electric protection to battery pack 3, but is heated easily expansion, this
The biggish specific heat capacity of Shi Liyong linear low density polyethylene can effectively reduce polyacrylic heat expansion degree, prevent from jacking up box cover 1, gather
The content of propylene depends on the content of linear low density polyethylene, to guarantee to guarantee that coefficient of thermal expansion control exists on the basis of insulating properties
In one critical field.
Tricresyl phosphate is as fire retardant, with the safety of Promoting Layered Buffer insulating materials.Tricresyl phosphate energy simultaneously
Enough it is used as a kind of secondary solvent, the safety of Promoting Layered Buffer insulating materials.But its density is big, excessive addition will affect electric vehicle
The specific capacity of battery case.
The averag density that insulating materials is buffered in the present embodiment is 1.15g/cm3。
