FIG. 1 is a schematic view of a sealing film according to an embodiment of the present disclosure; fig. 2 is a schematic view showing the use of the sealing sheet shown in fig. 1. For the purpose of illustration, only the structures described in connection with the present application are illustrated in the drawings.

The sealing rubber sheet 100 disclosed in at least one embodiment of the present application includes an aluminum foil 10 and a damper 30, where the aluminum foil 10 is used in cooperation with the damper 30 for cooling insulation and condensation prevention of the cab 200.

It is to be understood that the aluminum foil 10 is a material directly rolled into a thin sheet from metallic aluminum. Because the aluminum has silvery white luster, the aluminum has good heat radiation resistance. Secondly, the aluminum foil sheet 10 has good heat resistance and flame retardancy. In addition, the aluminum foil 10 has strong corrosion resistance. In the present embodiment, therefore, the sealing sheet 100 includes the aluminum foil 10, and the aluminum foil 10 is used to reflect heat radiation.

In practical application, sunlight outside the cab 200 is irradiated to the aluminum foil 10 adhered to the cab 200, and the aluminum foil 10 has silvery luster, so that sunlight irradiated to the cab 200, especially infrared light in the sunlight, can be effectively reflected. Further, since the infrared light mainly generating heat is reflected by the aluminum foil 10, it is effectively prevented that high-temperature heat outside the cab 200 is transferred into the cab 200, the energy consumption of the air conditioner is reduced, the driving comfort of the driver is improved, and the driving safety is facilitated.

It should be understood that the aluminum foil 10 may be classified into a single-sided polished aluminum foil and a double-sided polished aluminum foil according to the surface state. The single-side polished aluminum foil is a double-rolled aluminum foil 10, the thickness of which is usually not more than 0.025mm, and one side of the aluminum foil is bright and the other side of the aluminum foil is dark after being split. The double-sided smooth aluminum foil is an aluminum foil 10 rolled by a single sheet, the thickness is generally not less than 0.01mm, two sides of the aluminum foil are contacted with a roller, and the two sides of the aluminum foil are divided into a mirror-surface double-sided smooth aluminum foil and a common double-sided smooth aluminum foil due to different roughness of the roller surface.

Therefore, when the aluminum foil 10 is provided on the wall surface of the cab 200, a single-piece polished aluminum foil or a double-sided polished aluminum foil may be selected as necessary. In practical applications, a single-sided aluminum foil may be disposed in a region of the cab 200 having a relatively large thickness or a relatively good heat insulating property, and the bright side may be directed to the outside of the cab 200 to reflect solar radiation light or other heat sources. A double-sided aluminum foil may be disposed in a region of the cab 200 having a thin wall thickness or poor heat insulation to reflect solar radiation light or other heat sources.

It is understood that the above description is only for illustrative purposes and is not to be construed as limiting the present application, and for example, a single-sided aluminum foil and a double-sided aluminum foil may be simultaneously disposed in different areas of the cab 200 according to the use requirement to balance the heat insulation cost and the heat insulation effect.

In the embodiment of the present application, the aluminum foil 10 may be a double-sided aluminum foil to ensure the heat insulation effect of the cab 200 and improve the driving comfort of the driver.

In some embodiments, the aluminum foil 10 has a thickness of 0.065-0.085 mm. So, can effectively guarantee driver's cabin 200 thermal-insulated effect, improve driver's driving comfort, have good economic nature simultaneously.

In a preferred embodiment, the thickness of the aluminum foil 10 may be 0.075 mm, which does not affect the heat insulation effect of the aluminum foil 10, in consideration of cost control.

It will be appreciated that the soft, ductile aluminum foil 10 is fully capable of adhering to the sheet metal surfaces of various areas of the cab 200. However, it is very difficult to weld the aluminum foil 10 to the body-in-white surface area of the cab 200, and the surface of the aluminum foil 10 is smooth and is not easily adhered. Therefore, in some embodiments, the sealing sheet 100 further includes a damper 30.

In some embodiments, the damping sheet 30 is disposed on one side of the aluminum foil 10, and one side of the damping sheet 30 away from the aluminum foil 10 is used for covering the inner wall of the cab 200. The damping fin 30 is made of high molecular polymer as a raw material, and various nontoxic chemical additives and effective fillers are added for refining, and has the characteristics of strong adhesive force, good heat insulation and good sealing property.

In practical application, after the aluminum foil 10 and the damping plate 30 are combined together, the surface of the aluminum foil 10 is completely airtight, and the ultrathin aluminum foil 10 can be freely changed in curvature according to the body-in-white surface of the cab 200 area so as to be completely attached. Meanwhile, the side of the damping plate 30 away from the aluminum foil 10 is coated with glue to ensure the sealing property of the joint surface of the sealing rubber sheet 100 and the body-in-white.

Further, since the damper 30 has a good ability to block heat transfer, most of the heat is reflected by the aluminum foil 10, and even if a small portion of the heat passes through the aluminum foil 10 to the damper 30, the continued transfer of the portion of the heat is well blocked, thereby improving the comfort of the cab 200.

Similarly, the damping sheet 30 can prevent cool air outside the cab 200 from directly passing through the wall of the cab 200 to the inside of the cab 200. Thus, the comfort of the cab 200 is improved, and the driving safety is facilitated.

Furthermore, the sealing film 100 with good heat resistance is adhered to the inner wall of the cab 200, so that on one hand, cool air outside the cab 200 is prevented from entering the cab 200, and on the other hand, moist and hot air, such as water vapor, which is to be reflected to the inner wall surface of the cab 200 can be isolated. So, can avoid the direct inner wall surface with driver's cabin 200 of damp and hot air in the driver's cabin 200 to contact and the phenomenon of the frost condensation, improve the comfort level in the driver's cabin 200, be favorable to driving safety.

Further, after the damping film is subjected to heat hardening treatment, the adhesiveness and the sealing property between the sealing film 100 and the inner wall of the cab 200 can be further ensured.

In some embodiments, the damping film comprises a butyl damping film. The butyl damping film is heat-insulating, cool-insulating, flame-retardant and high in viscosity, and can be adhered to the surface of metal. And secondly, the strength of the butyl damping film after baking and hardening is good, and the rigidity of the bonding area can be improved. In addition, the butyl damping film is low in cost.

In some embodiments, the thickness of the butyl damping film is 0.8-1.2 mm to ensure good thermal and cold insulation performance and good economy.

In the preferred embodiment, the thickness of the butyl damping film is 1.0 mm. The butyl damping film with the thickness has good cold insulation and heat insulation effects when being applied to a commercial vehicle.

In some embodiments, the sealing film 100 further comprises a release paper 50, and the release paper 50 is releasably covered on the other side of the damping film away from the aluminum foil 10. Specifically, in some embodiments, the damping rubber sheet has a first adhesive surface and a second adhesive surface opposite to the first adhesive surface, the first adhesive surface of the damping rubber sheet is pre-adhered to the aluminum foil 10, and the second adhesive surface is used for adhering to the inner wall surface of the cab 200. The second bonding surface is covered with release paper 50, so that the surface of the second bonding surface can be protected, and the bonding effect of the second bonding surface is prevented from being influenced by pollution.

Further, the damping film peeling device further comprises a label of the release paper 50 adhered to one side of the release paper 50 close to the damping film, wherein the label of the release paper 50 is exposed at the end part of the release paper 50 and can operatively drive the release paper 50 to peel off the damping film. Specifically, in some embodiments, a label of the release paper 50 is disposed on an edge of one side of the release paper 50, a part of the label of the release paper 50 is adhered and fixed to the release paper 50, and another part protrudes from an edge of an end of the release paper 50, so that the operation can be facilitated to remove the release paper 50, and the efficiency of removing the release paper 50 is improved.

The label of the release paper 50 can be a structure integrated with the release paper 50, or an independent structure adhered and fixed on the end of the release paper 50.

Further, can set up in any place from the peripheral edge of type paper 50 from the type paper 50 labeling, and quantity is not limited to one, can be a plurality of, and during the use through tearing off from type paper 50 labeling after type paper 50, the second face of bonding that can be convenient for the damping film bonds to the inner wall surface of driver's cabin 200.

As the same concept of the present application, there is also provided a commercial vehicle, which includes a cab 200 and the sealing film 100, wherein the sealing film 100 is disposed on the inner wall surface of the cab 200. In particular, in some embodiments, the cab 200 includes a roof beam, and the sealing sheet 100 is disposed on an inner wall of the roof beam. This commercial car, the phenomenon of congealing water and congealing frost is few, and high temperature or low temperature outside the driver's cabin 200 are difficult for conducting to the driver's cabin 200 in, and the comfort level in the driver's cabin 200 is high, and driver and passenger's driving and take experience are good, and driving safety degree is high, can be applicable to multiple vehicle environment such as long-distance and short-distance.
