Description

Technical Field

[0001] The utility model relates to the technical field of new energy automobile interior decoration, in particular to a fireproof foot pad. Background Art

[0002] In recent years, with the improvement of environmental awareness and the continuous development of technology, new energy vehicles have been widely promoted and applied around the world, and it can be foreseen that new energy vehicles will become the development direction of the future automobile industry.

[0003] At present, the battery pack is located at the bottom of the foot pad, which is a common layout in the design of new energy vehicles. Placing the battery pack at the bottom of the foot pad can utilize the space at the bottom of the vehicle, better balance the stability of the vehicle, and improve the space utilization of the vehicle. However, battery pack explosion is an extremely serious and dangerous situation in new energy vehicles. When the new energy battery pack burns, if the car foot pad does not have fire resistance, it will seriously affect the escape time of the passengers. The existing flame-retardant foot pads are aimed at ordinary cars without the risk of deflagration. The position of the flame-retardant layer is generally set to prevent the foot pad from burning from the top, and the fire resistance cannot achieve the effect of non-combustibility. Therefore, it is urgent to design a fire-retardant foot pad to prevent the rapid spread of open fire under the foot pad and provide passengers with a longer escape time. In addition, the existing ordinary flame-retardant foot pads are generally provided with a non-fireproof anti-skid layer at the bottom layer. Since the entire foot pad is usually stacked together and the layers are tightly combined, the anti-skid layer will also affect the thermal insulation of the entire foot pad after burning. Utility Model Content

[0004] The utility model aims to provide a fireproof foot pad, which effectively solves the problem that the existing fireproof foot pad cannot be applied to new energy vehicles with the risk of explosion.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A fireproof foot mat comprises a surface layer, a sponge layer and a fireproof and anti-slip layer which are stacked in sequence from top to bottom, and the fireproof and anti-slip layer has Class A fireproof performance.

[0007] In some embodiments, the fireproof and anti-slip layer is alumina flame retardant cotton or pre-oxidized silk flame retardant cloth.

[0008] In some embodiments, the surface layer includes a leather layer and a nano-silicon antifouling layer located on the leather layer.

[0009] In some embodiments, the thickness of the nano-silicon anti-fouling layer is 18-25 μm.

[0010] In some embodiments, the nano-silicon antifouling layer is made of latex-grade nano-silicon.

[0011] In some embodiments, the leather layer is made of solvent-free leather.

[0012] In some embodiments, the sponge layer is a high-density polyurethane sponge layer.

[0013] In some embodiments, a nano-composite catalyst anti-formaldehyde layer is further provided between the nano-silicon anti-fouling layer and the leather layer.

[0014] In some embodiments, the fireproof and anti-slip layer is sprayed with a nano-composite catalyst material.

[0015] In some embodiments, the nanocomposite catalyst material is titanium dioxide phosphate.

[0016] The fireproof foot pad provided by the utility model is provided with an integral fireproof and anti-skid layer with Class A fireproof performance, that is to say, the non-combustible material is applied to the foot pad of the new energy vehicle, which can prevent the rapid spread of fire after the battery pack of the new energy vehicle explodes, and provide passengers with a longer escape time. In addition, since the fireproof and anti-skid layer is an integral body made of a material, it can prevent the entire foot pad from burning from the bottom of the fireproof foot pad, avoiding the lower part of the foot pad from burning, thereby making the thermal insulation of the entire foot pad better. Setting the fireproof and anti-skid layer as the same layer also makes the structural layers of the fireproof foot pad fewer and convenient to manufacture. In addition, the fireproof foot pad of this embodiment is provided with a sponge layer, which can support the surface layer and further improve the thermal insulation of the fireproof foot pad.

[0022] The core of the utility model is to provide a fireproof foot pad, which effectively solves the problem that the existing fireproof foot pads cannot be applied to new energy vehicles with the risk of explosion.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Please refer to Figure 1 to Figure 2 , Figure 1 This is one of the structural schematic diagrams of the fireproof foot pad provided in a specific implementation mode of the utility model; Figure 2 The second structural schematic diagram of the fireproof foot pad provided by a specific implementation method of the utility model.

[0025] In a specific embodiment, the fireproof foot mat provided by the utility model comprises a surface layer 1, a sponge layer 2 and a fireproof and anti-skid layer 3 which are stacked in sequence from top to bottom, wherein the fireproof and anti-skid layer 3 has the Class A fireproof performance specified in the national standard - Classification of Combustion Performance of Building Materials and Products (8624-2012), and the material with Class A fireproof performance can achieve the technical effect of non-combustibility. The fireproof foot mat is provided with an overall fireproof and anti-skid layer 3 with Class A fireproof performance, that is, the non-combustible material is applied to the foot mat of a new energy vehicle, which can prevent the fire from spreading rapidly after the battery pack of the new energy vehicle explodes, and provide passengers with a longer escape time.

[0026] In addition, since the fireproof and anti-skid layer 3 is an integral body made of a material, the entire foot pad can be prevented from burning from the bottom of the fireproof foot pad, and the lower part of the foot pad can be prevented from burning, thereby making the thermal insulation of the entire foot pad better. The fireproof layer and the anti-skid layer are arranged on the same layer, and the structural layers of the fireproof foot pad are also reduced, which is convenient to manufacture. In addition, the fireproof foot pad of this embodiment is provided with a sponge layer, which can support the surface layer and further improve the thermal insulation of the fireproof foot pad. The fireproof foot pad of this embodiment is provided with a surface layer so that the foot pad has aesthetics, wear resistance and stain resistance.

[0027] In a specific embodiment, the fireproof and anti-skid layer 3 is alumina flame retardant cotton or pre-oxidized silk flame retardant cloth. Alumina flame retardant cotton is a fire-resistant, heat-insulating and flame-retardant material. It is mainly made of alumina fibers. These fibers can maintain stability in high temperature environments and effectively prevent the spread of flames. Pre-oxidized fibers or pre-oxidized silks are obtained by high-temperature thermal stabilization treatment with polypropylene as raw materials. It has high flame retardancy, a limiting oxygen index greater than 45%, excellent thermal stability, and the fibers do not melt, soften, shrink, or drop during combustion, and are quasi-non-combustible products; it has good thermal insulation effect, acid and alkali corrosion resistance, chemical environment resistance, and radiation resistance; it has suitable textile processing performance, and the fabric is light, soft, and has good water absorption. Alumina flame retardant cotton and pre-oxidized silk flame retardant cloth also have good anti-skid properties. This embodiment applies alumina flame retardant cotton and pre-oxidized silk flame retardant cloth, which have both flame retardant and anti-skid effects in other fields, to the field of foot pads, solving the problem that new energy vehicles have higher requirements for fire resistance of foot pads.

[0028] like Figure 1 As shown, in a specific embodiment, the surface layer 1 includes a leather layer 12 and a nano-silicon antifouling layer 11 located on the upper part of the leather layer 12. The nano-silicon antifouling layer 11 is an antifouling coating of nano-silicon sprayed on the upper part of the leather layer 12, which has the effect of waterproofing and dustproofing. At the same time, the nano-silicon antifouling layer can also play a role of curing and anti-wearing.

[0029] Based on the above specific implementation, the thickness of the nano silicon antifouling layer 11 is 18-25 μm. Compared with the 12-15 μm thick antifouling layer on the market, the antifouling layer of the fireproof mat is relatively thick and has better wear resistance.

[0030] Based on the above specific implementation, the nano-silicon antifouling layer 11 is made of latex-grade nano-silicon. The latex-grade nano-silicon has strong binding force and has excellent antifouling effect after 6000 revolutions of wear resistance, while ordinary silicone coating has no antifouling effect after 1500 revolutions of wear resistance.

[0031] Based on the above specific implementation, the leather layer 12 is made of solvent-free leather. The production process of solvent-free leather does not require the use of chemical substances such as organic solvents, and no organic solvents are left in the leather, making the air in the car more environmentally friendly and making the leather more tough and durable.

[0032] Based on the above specific implementation, the sponge layer 2 is a high-density polyurethane sponge layer. The high-density polyurethane sponge has high elasticity and shock-absorbing performance, strong support for the leather layer, and the leather layer is not easy to wrinkle, which can effectively improve the service life of the fireproof foot pad.

[0033] like Figure 2As shown, in a specific embodiment, a nano-composite catalyst anti-formaldehyde layer 13 is further provided between the nano-silicon anti-fouling layer 11 and the leather layer 12. Thus, the fireproof foot pad of this embodiment has the three anti-fire, anti-fouling and anti-formaldehyde functions. Since the nano-silicon anti-fouling layer on the top of the fireproof foot pad is transparent and breathable, it does not affect the use of the nano-composite catalyst anti-formaldehyde layer, and can play a role in curing and preventing wear of the nano-composite catalyst anti-formaldehyde layer.

[0034] In a specific embodiment, the three fireproof and anti-skid layers are sprayed with nano-composite catalyst materials. The fireproof and anti-skid layer of the bottom layer of the fireproof foot mat is sprayed with nano-composite catalyst materials, which can purify harmful gases such as VOC formaldehyde released from the original car carpet. In addition, the spraying method can also increase the contact area between the nano-composite catalyst material and the fireproof and anti-skid layer. The high-nano composite catalyst material used in the fireproof and anti-skid layer is a high-performance composite catalyst material that does not require light. Specifically, the nano-composite catalyst material can be titanium dioxide phosphate.

[0035] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0036] The fireproof foot pad provided by the utility model is introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model. Therefore, the utility model will not be limited to the embodiments shown in this article, but will conform to the widest range consistent with the principles and novel features disclosed herein.
