Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
The utility model embodiment includes:
A kind of thin plate for refusing battery fluid and high temperature resistant heat insulation of new-energy automobile lithium-ion-power cell, comprising: elasticity two
Silica aerogel sheet material 1 and eptfe membrane 2,1 at least one side of elastic silica aerogel sheet material are compounded with swollen
Body polytetrafluoroethylene film 2.
As depicted in figs. 1 and 2, the single or double of elastic silica aerogel sheet material 1 is compounded with e-PTFE second
Alkene film 2.
Preparation method includes: to prepare elastic silica aerogel sheet material 1 first, then in eptfe membrane 2
Upper coating adhesive, it is compound with the lamination of elastic aeroge sheet material single or double, it finally examines, be heating and curing.
As shown in figure 3, elastic silica aerogel sheet material 1 is coated with eptfe membrane 2 comprehensively.
Preparation method includes: to prepare elastic silica aerogel sheet material 1 first, the elastic aeroge cut out with finishing die
Then part coats elastic aeroge part with the eptfe membrane 2 of single spreading is comprehensive, finally examines, heats admittedly
Change.
Wherein, the microporous barrier of expanded PTFE high-performance fiber, 92% or more is 0 ~ 15 micron openings in the porous material
Subtle, the cavity in multilayer abnormity aperture that interconnects that diameter is constituted.EPTFE membrane has chemical inertness good corrosion-resistant, thin
Water oleophobic is dredged and refuses excellent properties, the ePTFE membranes such as battery fluid no leakage, uvioresistant, nonflammable and high-low temperature resistant and adapt to
Various amblent air temperature variations are played without influencing its performance.
Elastic silica aerogel is a kind of micro-nano permeability elastomer vibration damping aerosil new varieties material,
It is the most light solid material of current engineer application, new-energy automobile lightweight can be made more energy efficient.What is be made from it is high-elastic
Property the various sheet material thermal coefficients of aerosil be 0.015 ~ 0.04 W/ (mK), it is even lower, and have it is super-hydrophobic,
It is use temperature range wide (- 80 ~ 350 DEG C), service life length, resistance to compression, nontoxic.
The preparation method of elastic silica aerogel sheet material 1 is: the flocculating agent of 100 ~ 120ml is added to 800 ~
Uniform stirring in the solvent of 1000ml, revolving speed are 50 ~ 300 turns/min, and the methyltrimethoxysilane of 160 ~ 180ml is then added
It with the silicon source of 90 ~ 120ml, stirs evenly, revolving speed is 50 ~ 300 turns/min, and the gel promotor of 150 ~ 170ml is added, stirs again
Mix uniformly, revolving speed be 50 ~ 300 turns/min, aged gel formed sheet wet gel, then carry out at least twice solvent displacement,
It obtains blocky wet gel and is dried, can be prepared by elastic silica aerogel sheet material 1.
In addition, fire retardant is added and is stirred while gel promotor is added, the sheet that aged gel is formed is wet solidifying
Glue can be prepared by the elastic silica aerogel sheet material 1 with flame retarding function after solvent displacement, drying.
Fire retardant is preferably environment friendly halogen-free fireproof agent, the gentle phosphorus nitrogen system expanding fire retardant derived from one of collection carbon source, acid source
It or is melamine and its compound of phosphorus.
Phosphorus nitrogen system expanding fire retardant: product collection carbon source, acid source and the gas source and one are decomposed simultaneously under high temperature action
And esterification expansion rapidly.Non-flammable steam is released in initial phase and generates endothermic effect, and and then free phosphoric acid promotees
