Description
[technical field]
Present invention relates particularly to a kind of flame-proof battery box cover LFT-D production technology and flame-proof battery box covers.
[background technique]
Now with national automotive light weight technology and the policy of new energy vehicle, the power battery of new-energy automobile is each family
New energy vehicle reach Battery Plant exploitation emphasis.Wherein the upper cover major part producer of battery pack is all sheet metal component, for light
The considerations of quantization, develops the product of many composite material classes currently on the market, and wherein long glass fiber-reinforced polypropylene is molded online
The product weight loss effect for forming (LFT-D) is more obvious.
The product of LFT-D technique is more obvious than sheet metal component weight loss effect, and shaping efficiency is high, and product can achieve the fire-retardant effect of V0
Fruit, but in the national standard of battery pack, battery pack is to external bonfire test process (GB/T 31467.3-7.10) requirement:
1, the square position size for holding gasoline should be more than 20~50cm of test object；
2, square position height is not higher than gasoline level 8cm；
3, the bottom surface distance 50cm of gasoline level and test object entirety；
4, there should be support inside test object, guarantee that baked wheaten cake process measurand does not occur collapsing phenomenon；
5, test object is directly exposed to flame combustion 70s, then covers food tray with cover board and continue for test 60s；
6, food tray or test object are removed, whether the flame observed in test object extinguishes in 120s.It is most of at present
Material producer increases the flame retardant effect of material by the fire retardant added with halogen or Halogen, but according to existing experiment feelings
Condition, improves merely the flame retardant effect of product by fire retardant, is still unable to reach the requirement of external baked wheaten cake, and increases fire-retardant
Ratio will increase dramatically the cost of material, and weight loss effect also weakens very much, and most of fire retardant currently used in the market is all
It is the substance for having halogen fire retardant, belonging to not environmentally of bromine system, so fire retardant is fewer, it is more environmentally friendly.
[summary of the invention]
One of the technical problem to be solved in the present invention is to provide a kind of flame-proof battery box cover LFT-D production technology.
The present invention is implemented as follows: a kind of flame-proof battery box cover LFT-D production technology, according to battery box cover shape
Shape, arranges a glass-fiber-fabric aluminium foil to match with battery box cover shape in advance in mold, and by the aluminium foil of glass-fiber-fabric aluminium foil
Down, blank is stacked on the glass cloth cover of glass-fiber-fabric aluminium foil, then carries out LFT-D compression molding, glass-fiber-fabric aluminium after molding
Foil bonds together with battery box cover.
The second technical problem to be solved by the present invention is to provide a kind of flame-proof battery box cover.
The present invention is implemented as follows: a kind of flame-proof battery box cover, including a battery box cover and a glass-fiber-fabric aluminium foil,
The glass-fiber-fabric aluminium foil is coated on the inner surface of battery case upper cover.
The present invention has the advantages that the flame retardant level of battery box cover can be significantly improved, product density is reduced, weight loss effect
Obviously.
[Detailed description of the invention]
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of flame-proof battery box cover in the present invention.
[specific embodiment]
Referring to Fig. 1, a kind of flame-proof battery box cover 100, including a battery box cover 1 and a glass-fiber-fabric aluminium foil 2, it is described
Glass-fiber-fabric aluminium foil 2 is coated on the inner surface of battery box cover 1.
Referring again to Fig. 1, a kind of flame-proof battery box cover 100LFT-D production technology, according to 1 shape of battery box cover,
Arrange a glass-fiber-fabric aluminium foil 2 to match with 1 shape of battery box cover in mold in advance, and by the aluminium foil surface of glass-fiber-fabric aluminium foil 2
Downward (without binding force between aluminium foil surface and blank), blank is stacked on the glass cloth cover of glass-fiber-fabric aluminium foil 2, then carries out LFT-
D compression molding, glass-fiber-fabric aluminium foil 2 bonds together with battery box cover 1 after molding, i.e. 1 inner surface of battery box cover wraps up
Layer of glass fiber fabric aluminium foil 2.
Referring again to Fig. 1, LFT-D technique, that is, long glass fiber-reinforced polypropylene is pressed and molded online, by battery box cover 1
This layer of glass fiber fabric aluminium foil 2 on surface is played a supporting role during outside is burnt, and flame only can be on flame-proof battery box
The burning of 100 outer surface of lid, flame will not be burnt inside flame-proof battery box cover 100, and glass-fiber-fabric aluminium foil 2 becomes a skeletal support
Will not be by fire to burning down, glass-fiber-fabric aluminium foil 2 is able to maintain the appearance profile of battery box cover 1, reduces contact combustible, increases resistance
Fuel cell box cover 100 leaves the self-extinguishment after fire source.
The invention has the following advantages that
(1) flame-proof battery box cover 100 of the invention can be by burning in GB/T31467.3 standard to outside battery pack
Requirement.
(2) increase self-extinguishment effect by increasing glass-fiber-fabric aluminium foil 2, can achieve compared to by increasing fire retardant ratio
Good flame retardant effect, it is 1.5g/cm that fire retardant ratio, which increases highest product density, at present3, and pass through glass-fiber-fabric aluminium foil 2
Density of material only reaches 1.15g/cm3, the weight of monolith glass-fiber-fabric aluminium foil 2 is 100g or so, and product density reduces, and loss of weight is about
788g, weight loss effect is obvious, more advantageous to automobile batteries.
Although specific embodiments of the present invention have been described above, those familiar with the art should be managed
Solution, we are merely exemplary described specific embodiment, rather than for the restriction to the scope of the present invention, it is familiar with this
The technical staff in field should be covered of the invention according to modification and variation equivalent made by spirit of the invention
In scope of the claimed protection.
