[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment

[0023] As Figure 1 ,Figure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , an embodiment of the present utility model provides a tarpaulin with good flame retardancy performance, which includes a tarpaulin body 1, a flame retardant layer 2, a protective layer 3 and a flame retardant packet 4. Flame retardant layers 2 are fixedly attached to both sides of the tarpaulin body 1 through adhesive layers 5, which facilitates stably connecting the flame retardant layers 2 to the surface of the tarpaulin, forming a stable flame retardant and fireproof layer, improving the flame retardancy performance of the tarpaulin, reducing the damage of the tarpaulin during a fire, extending the service life, and the base layer 201 of the flame retardant layer 2 is composed of a reinforcing grid 2011 and a first filler 2012. A wrapping layer 202 is attached to the surface of the base layer 201, and a protective layer 3 is fixedly attached to the flame retardant layer 2 through an adhesive layer 5. Uniformly distributed flame retardant packets 4 are arranged in the protective layer 3. By using the cooperation of the protective layer 3 and the adhesive layer 5, the flame retardant packets 4 are stably connected to the tarpaulin, forming a stable fireproof and flame retardant layer on the tarpaulin, further improving the fireproof performance of the tarpaulin. When used together with the flame retardant layer 2, two stable fireproof and flame retardant layers are formed on the surface of the tarpaulin, greatly improving the fireproof performance of the tarpaulin, reducing the damage caused by fire to the tarpaulin, extending the service life of the tarpaulin, ensuring long-term stable use. At the same time, this flame retardant method does not require modification of the existing tarpaulin, only need to paste the flame retardant layer 2 and the protective layer 3 on the surface of the existing tarpaulin, which is simple and convenient to produce, reduces production costs, has good flame retardancy performance and is easy to use.

[0024] As Figure 2 and Figure 3 shown in Figure 2 and Figure 3 , in some embodiments, the reinforcing grid 2011 in the base layer 201 is composed of transverse and longitudinal carbon fiber warp threads that are woven perpendicular to each other. The first filler 2012 is uniformly distributed in the gaps formed by the interweaving of the transverse warp threads and the longitudinal warp threads. The first filler 2012 is a flame retardant. The reinforcing grid of carbon fiber facilitates improving the strength of the entire tarpaulin, and at the same time stably attaches the flame retardant to the surface of the tarpaulin, forming a stable flame retardant layer on the surface of the tarpaulin, providing a second layer of flame retardant protection for the tarpaulin. During a fire, it can retard the burning of the tarpaulin, further improving the flame retardancy performance of the tarpaulin and ensuring long-term stable use of the tarpaulin. And the wrapping layer 202 is attached to both sides of the base layer 201 to ensure that the flame retardant can be stably attached to the reinforcing grid 2011, enabling the two to stably cooperate to form a stable composition layer and forming a reinforcing layer on the surface of the tarpaulin to enhance the strength of the tarpaulin. Multiple layers of reinforcing grids 2011 that are stacked on top of each other and evenly spaced are provided in the base layer 201. Adjacent layers of the reinforcing grids 2011 are interwoven and connected through connecting warp threads, stably connecting the multiple layers of reinforcing grids 2011 together to form an integral body, serving as the reinforcing layer of the tarpaulin and the attachment of the flame retardant, ensuring stable use.

[0025] As Figure 1 and Figure 4As shown, in some embodiments, the interior of the flame retardant package 4 is filled with a second filler 401 evenly distributed. The second filler 401 is a flame retardant. The outer packaging body of the flame retardant package 4 stably wraps the flame retardant, so that the flame retardant can be stably stored in the protective layer. And the flame retardant package 4 is one or more of a strip shape, a disc shape, and a rectangular sheet shape. The thickness of the flame retardant package 4 is less than the thickness of the protective layer 3, and the outer packaging body of the flame retardant package 4 is wrapped by the protective layer 3. During the production process, the shape of the flame retardant package 4 is selected according to actual use requirements and placed therein when the protective layer 3 is formed, and they are integrally formed together to form a stable protective layer on the surface of the tarp body 1. At the same time, the flame retardant package 4 is wrapped and protected by the protective layer 3 to ensure stable use, forming evenly distributed flame retardant areas in the protective layer 3 to form the first layer of flame retardant protection for the tarp. During the process of the tarp being burned, after the protective layer 3 is damaged, the flame retardant package 4 is exposed. Under the high temperature of the fire, the outer packaging body is damaged and the flame retardant leaks out. Subsequently, under the action of the high temperature, rapid gasification can occur in this area to generate flame retardant gas, inhibit the progress of combustion, retard the tarp, reduce the smoothness of the tarp, and improve the flame retardant performance of the tarp.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
