Description
Technical field
The invention belongs to fire proofing material field, more particularly to a kind of fireproof felt.
Background technology
At the beginning of New Energy Sources In China automobile industry starts from 21 century.2001, new-energy automobile research project was put into country " ten
Five " " 863 " the great scientific and technological problem during, and planned with gasoline car as starting point, to the strategy that hydrogen-powered vehicle target is drive on boldly.
Since Eleventh Five-Year Plan, China proposes " energy-conservation and new-energy automobile " strategy, and government pays high attention to research and development and the product of new-energy automobile
Industry, forms complete new-energy automobile research and development, exemplary layout.New-energy automobile refers in addition to gasoline, Diesel engine
All other energy automobile.Including fuel cell car, hybrid vehicle, hydrogen-powered vehicles and solar telephone etc.,
Its discharge amount of exhaust gas is than relatively low.
New-energy automobile on sale is mostly hybrid vehicle and pure electric automobile in current Chinese market.Due to its adaptation
The trend of contemporary environmental protection and energy saving, the development of new-energy automobile is very rapid now, and the scope that it is used is increasing.It is new from the whole world
From the point of view of the development of energy automobile, its electrical source of power mainly includes lithium ion battery, Ni-MH battery, fuel cell, lead-acid battery, super
Level capacitor.Because the power that running car needs is very big, the new-energy automobile of power is provided in order to guarantee using electric power
Normally travel is, it is necessary to battery compartment provides larger current for a long time, it is ensured that the offer of power.When on-vehicle battery exports electric energy for a long time
Afterwards, it can be that security consideration can set anti-in battery compartment so that cell body substantially generates heat to carry out chemical reaction in battery for a long time
Fiery felt is used as fire-retardant, prevents battery because unexpected occur security incident on fire.Existing fireproof felt simple structure, easily becomes
Shape, uses splicing construction form in battery compartment, and flame retardant effect is poor, it is impossible to meet the related mark of the new energy field of national regulation
It is accurate.
Therefore, for the new-energy automobile of the energy is provided using battery compartment, it is to avoid battery breaks down very because of overheat
To initiation fire hazard, ensure personnel's safe escape into those skilled in the art's problem demanding prompt solution.
The content of the invention
To overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of new energy car battery storehouse fireproof felt and
Manufacture craft, anti-flaming function is strong, non-ignitable, high temperature resistant is unlikely to deform to meet naked light, and manufacture craft is simple, saves production cost.
To achieve the above object, the present invention is adopted the following technical scheme that：A kind of new energy car battery storehouse fireproof felt, its
Feature is that fireproof felt section has three layers, and upper strata is upper strata carbon cloth, and intermediate layer is blending high temperature cotton, and bottom is bottom carbon fiber
Cloth；The upper strata carbon cloth and bottom carbon cloth are made up of carbon fiber and glass fibre, and thickness is 0.47~0.51mm,
With anti-flaming function；The blending high temperature cotton thickness is 3~6mm, with fire-retardant and heat insulating function；The blending high temperature cotton is by glass
Glass fiber is constituted, central filler nano powder composition nanometer bisque；The upper and lower surface of blending high temperature cotton scribbles Environment-friendlyglue glue to be used for
Bond upper strata carbon cloth and bottom carbon cloth.
Further improve, the upper strata carbon cloth and lower floor's carbon cloth size are adjacent to the cooperation of blending high temperature cotton, four
While leaving the surplus of 3~6mm, prevent fire prevention felt product from being damaged to the outer wall of blending high temperature cotton in packaging, transport, installation,
Blending high temperature cotton is also prevented from when using exposed outside.
Further improve, the described upper and lower surface of blending high temperature cotton respectively with upper strata carbon cloth and bottom carbon cloth
Contact surface be the one kind in plane or male and fomale(M＆F)；The cross sectional shape of described male and fomale(M＆F) is in triangle, trapezoidal or rectangle
It is a kind of.Male and fomale(M＆F) form can increase the contact area of contact surface, bond more firm.
A kind of manufacture craft of new energy car battery storehouse fireproof felt, is characterized in that the technique is entered in accordance with the following steps
OK：
1) cut：Being required according to size, cut and make upper strata carbon cloth and bottom carbon cloth, four sides leave 5~
The surplus of 12mm；
2) fireproof felt head product shaping：The blending high temperature cotton and Environment-friendlyglue glue that will be filled with nano powder reconcile after cutting, and put down
It is layered on bottom carbon cloth, upper strata carbon cloth is laid in blending high temperature cotton upper surface；
3) it is hot-forming：The preheating of high temperature hydraulic press is opened, the temperature of high temperature hydraulic press to 300~500 DEG C, pressure 3 is adjusted
Between~5Mpa, take fireproof felt head product and be put into high temperature hydraulic press and had a fling at, hot pressing time 130~160S is hot-forming
Taken out after end, censorship；
3.1) after the assay was approved according to step 3) in temperature and pressure produced；
3.2) disqualified upon inspection, carries out temperature adjustment, pressure regulation, and product has a fling at, until qualified；
4) chamfered edge shaping：By hot-forming fireproof felt chamfered edge shaping, upper strata carbon cloth and bottom carbon are fine after chamfered edge
Stay 3~6mm surpluses in dimension cloth four side.
The fireproof felt of the size design production according to battery compartment is layered on above battery compartment with the middle of base plate, is not prevented only
Fire, heat insulating function, moreover it is possible to play a part of buffering；When automobile runs into naked light, can effectively intercept spreading, making passenger for naked light
There is time enough to shift, avoid personal injury.
It is an advantage of the invention that fireproof felt is used primarily in new energy pure electric motor coach power cell storehouse, with fire prevention, heat insulating function,
Anti-flaming function is strong, non-ignitable, high temperature resistant of meeting naked light up to 800~1000 DEG C it is indeformable, naked light can be intercepted 8 minutes or so；Manufacture craft
Simply, low production cost；Heat-resisting, firing resistance is higher by GB：Rule in GB8410-2006 (automotive interior material combustion characteristics)
Fixed technical requirements；Other fireproof felt of the present invention apply also for automotive upholstery fire prevention component and other need to prevent fires, it is fire-retardant
The field of structure.
