Description
Technical Field
The utility model relates to the field of heat insulation cotton, in particular to fireproof heat insulation cotton for an automobile battery.
Background
The heat-insulating cotton is a high-efficiency heat-insulating material, and has the characteristics of light weight, oxidation resistance, low heat conductivity, good flexibility, corrosion resistance, small heat capacity, sound insulation and the like. The automobile battery often uses the heat preservation cotton as thermal-insulated component, especially to electric automobile or oil-electricity hybrid vehicle, the volume of its storage battery is great usually, in order to avoid the heat transfer of battery to other spare parts on, need set up thermal-insulated cotton and carry out the separation to the heat.
However, although some insulation cotton on the market has unusual heat insulation performance, the fire resistance of the insulation cotton is generally poor. In view of the fact that the existing automobile storage battery technology is not completely mature, the automobile storage battery is occasionally subjected to a fire accident, and in order to guarantee the life and property safety of users, the heat insulation cotton with good fireproof performance is necessarily designed.
SUMMERY OF THE UTILITY MODEL
The technical scheme of the utility model aims at the situation and provides a fireproof heat-preservation cotton for an automobile battery for solving the problems, which is characterized in that: the fireproof heat-preservation cotton comprises: the top PI film, the steam coagulation felt layer, the aerogel layer and the bottom PI film are sequentially attached.
Further, the thickness of the top PI film is 0.05-0.08 mm.
Further, the thickness of the steam coagulation felt layer is 1.4-1.6 mm.
Further, the thickness of the aerogel layer is 1.4-1.6 mm.
Further, the thickness of the bottom layer PI film is 0.05-0.08 mm.
After the technical scheme is adopted, the utility model has the effects that: the fireproof heat-preservation cotton with the structure can play a good heat-insulation effect on one hand, plays an effective protection role on other parts of an automobile, has excellent fireproof performance on the other hand, can delay combustion even if the fire is started, and guarantees the life and property safety of a user.
Drawings
Fig. 1 is a schematic view of a hierarchical structure of the fireproof heat-preservation cotton according to the present invention.
Detailed Description
It is specifically noted that, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise; the meaning of "several" is at least one. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative positional relationship between the components, the movement, and the like in a certain posture, and if the certain posture is changed, the directional indicator is changed accordingly.
The technical solution of the present invention is further described by the following examples:
the utility model provides a fireproof heat-preservation cotton for an automobile battery, as shown in figure 1, the fireproof heat-preservation cotton comprises: the top PI film 1, the steam coagulation felt layer 2, the aerogel layer 3 and the bottom PI film 4 are sequentially attached to each other.
When in use, the bottom layer PI film 4 is attached to the automobile storage battery. The top PI film 1 and the bottom PI film 4 are polyimide films, have excellent high and low temperature resistance, can be used for a long time within a temperature range of-269-280 ℃, and can reach a high temperature of 400 ℃ in a short time; the aerogel layer 3 has a fine nano-network structure, and the nano-pores inhibit the conduction of gas molecules to heat, thereby effectively limiting the spread of heat.
More importantly, in the utility model, the fireproof heat-preservation cotton is added with the aerogel felt layer 2, the aerogel felt is a material which takes silica aerogel as a main material and is compounded in the reinforcing fiber, the aerogel felt has the fireproof performance of B1 grade to A grade, the burning speed is extremely slow, and the aerogel felt can provide enough time for a user to extinguish a fire or escape even in the case of fire.
Secondly, the aerogel felt is a solid heat-insulating material with the lowest heat conductivity coefficient in the 400 ℃ temperature region at present, the heat conductivity coefficient of the aerogel felt is about 0.02W/(m.k), and the heat conductivity coefficient of the aerogel in the 400 ℃ temperature region is about 0.07W/(m.k), and the combination of the two enables the fireproof heat-insulating cotton to have good heat-insulating performance.
Thirdly, in order to improve the heat insulation performance of the heat insulation cotton on the market, the heat insulation layer is thickened usually, and on the premise of the same heat insulation effect, the thickness of the steam condensation felt layer 2 is only a fraction of that of the traditional material, so that the whole thickness of the heat insulation cotton is reduced. In addition, because the fireproof heat-insulating cotton is simultaneously provided with the film layers made of different materials, namely the aerogel layer 2 and the aerogel layer 3, interface thermal resistance is formed between the aerogel layer 2 and the aerogel layer 3, and the fireproof heat-insulating cotton has a good blocking effect on electromagnetic wave radiation.
Therefore, the fireproof heat-preservation cotton with the structure can have a good heat-insulation effect on one hand, can effectively protect other parts of an automobile, has excellent fireproof performance on the other hand, can delay combustion even if a fire occurs, and guarantees the life and property safety of a user.
Specifically, the thickness of the top PI film 1 is 0.05-0.08 mm.
Specifically, the thickness of the steam coagulation felt layer 2 is 1.4-1.6 mm.
Specifically, the thickness of the aerogel layer 3 is 1.4-1.6 mm.
Specifically, the thickness of the bottom PI film 4 is 0.05-0.08 mm.
The above-described embodiments are merely preferred examples of the present invention, and not intended to limit the scope of the utility model, so that equivalent changes or modifications in the structure, features and principles of the utility model described in the claims should be included in the claims.
