[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "middle," "upper," "lower," "left," "right," "inner," "outer," "top," "bottom," "side," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] This utility model provides a flame-retardant nonwoven fabric.

[0023] The flame-retardant nonwoven fabric provided by this utility model includes: a reinforcing part 1, which includes a flame-retardant TPU skeleton 101 arranged in a crisscross pattern and a plurality of reinforcing ribs 102 arranged in a cross pattern. The reinforcing ribs 102 are disposed between the crisscrossing flame-retardant TPU skeletons 101 and are connected to adjacent flame-retardant TPU skeletons 101; a flame-retardant filler 2, which is disposed in the gap between the flame-retardant TPU skeleton 101 and the reinforcing ribs 102; and a nonwoven fabric layer 3, which is disposed on both sides of the skeleton 1.

[0024] In this invention, by providing an internal reinforcing part 1, which includes a crisscrossing flame-retardant TPU skeleton 101 and multiple intersecting reinforcing ribs 102, the reinforcing part 1 has a certain elasticity and good flame-retardant performance, ensuring the elasticity of this invention. Furthermore, flame-retardant filler 2 is provided in the gaps of the reinforcing part 1. When the outer non-woven fabric layer 3 burns, the flame-retardant filler leaks out. When heated, the flame-retardant filler decomposes and absorbs a large amount of heat, thereby reducing the surface temperature of the material and delaying the combustion process.

[0025] To facilitate production, the flame-retardant filler 2 is placed in a non-woven fabric bag. The non-woven fabric bag containing the flame-retardant filler 2 is then compacted. During the production of this utility model, the non-woven fabric bag containing the flame-retardant filler 2 is directly inserted into the gap between the flame-retardant TPU skeleton 101 and the reinforcing rib 102. A layer of glue is applied to the surface of the non-woven fabric bag. On the one hand, the non-woven fabric bag is bonded and fixed to the non-woven fabric layer 3. On the other hand, it can block the air pores on the non-woven fabric bag to a certain extent, preventing the non-woven fabric bag from leaking air and causing the flame-retardant filler 2 inside to loosen.

[0026] Please see Figure 1 In one embodiment of this utility model, the thickness of the flame-retardant filler 2 is the same as the thickness of the reinforcing part 1.

[0027] In this embodiment, the thickness of the flame-retardant filler 2 is the same as that of the reinforcing part 1, which can effectively prevent the part where the flame-retardant filler 2 is installed from bulging or collapsing.

[0028] Please seeFigure 1 In one embodiment of this utility model, the reinforcing rib 102 is made of the same material as the flame-retardant TPU skeleton 1, and the reinforcing rib 102 and the flame-retardant TPU skeleton 101 are integrally formed.

[0029] In this embodiment, the integrally formed reinforcing part 1 has good mechanical properties and is not easily broken.

[0030] Please see Figure 1 In one embodiment of this utility model, the thickness of the reinforcing part 1 is 1.5-2mm.

[0031] In this embodiment, the thickness of the reinforcing part is set to 1.5mm-2mm, which ensures flame retardancy without making the thickness of the present invention too high.

[0032] Please see Figure 1 In one embodiment of this utility model, the nonwoven fabric layer 3 and the reinforcing part 2 are heated and melted into a whole.

[0033] In this embodiment, separation of the nonwoven fabric layer 3 can be effectively prevented.

[0034] Please see Figure 1 In one embodiment of this utility model, the flame-retardant filler 3 is aluminum hydroxide or silicate.

[0035] In this embodiment, when the outer non-woven fabric layer 3 burns, the flame-retardant filler 2 leaks out. The flame-retardant filler decomposes when heated, absorbing a large amount of heat, thereby reducing the temperature of the material surface and delaying the combustion process.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and the scope of this utility model is defined by the appended claims and their equivalents.
