[0015] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] First Embodiment

[0017] In combination with Figure 1-2 This embodiment will be described in detail. A fire-retardant escape and fire-fighting blanket includes: a main body of the fire-fighting blanket 1, and triangular cloths 2 are respectively arranged at the four corners of the main body of the fire-fighting blanket 1; two sides of the triangular cloth 2 and the corners of the main body of the fire-fighting blanket 1 are connected by sewing, so that a cavity 3 with an opening is formed between the main body of the fire-fighting blanket 1 and the triangular cloth 2; both the main body of the fire-fighting blanket 1 and the triangular cloth 2 are made of fire-retardant fabric 4; the fire-retardant fabric 4 includes a first fire-retardant layer 5, and the first fire-retardant layer 5 is woven by fire-retardant yarns; the fire-retardant yarns are pre-oxidized fiber yarns or aramid pre-oxidized fiber blended yarns.

[0018] When the fire-retardant escape and fire-fighting blanket is used for protection and escape, the cavity 3 formed at any corner of the main body of the fire-fighting blanket 1 can be put on the head to avoid the fire-fighting blanket being easily detached when covering the body. Hold both sides of the fire-fighting blanket tightly with both hands, so that the main body of the fire-fighting blanket 1 wraps the body inside, which can play a role in isolating the heat source and the flame.

[0019] The pre-oxidized fiber is obtained by heat stabilizing PAN fiber in an oxidizing atmosphere. It is a new type of flame-resistant fiber that emerged with the development of carbon fiber and is an intermediate product in the manufacturing process of carbon fiber. Compared with aramid fiber, it has a higher use temperature, better flame retardant effect, and lower price, and also has the safety, good textile processing and wearing comfort performance of other fibers. It is widely used in the fields of construction, military, fire protection, automotive, chemical industry, etc. Specifically, in this embodiment, the flame-retardant yarn is an aramid / pre-oxidized fiber 40 / 60 blended yarn, which is stronger than the pre-oxidized fiber yarn, enhancing the wear resistance and temperature-resistant flame retardant effect.

[0020] Further, an aluminum glue coating 6 is attached to one side of the first flame-retardant layer 5. Specifically, the aluminum glue coating 6 includes aluminum glue A and aluminum glue B. First, apply aluminum glue A on the surface of the flame-retardant fabric 4, dry it in an electric heating blast drying oven at 100°C for 3 minutes, then raise the temperature to 150°C, place it for 10 minutes and then take it out. Then apply aluminum glue B on the surface of the aluminum glue A coating, and then dry it in an electric heating blast drying oven at 100°C for 3 minutes, and then raise the temperature to 150°C, place it for 10 minutes and then take it out. The process formula of aluminum glue A is: oil-based polyurethane: 100%, adhesive: 0 - 10%, cyclized phosphate flame retardant: 0 - 20%, methyl ethyl ketone: 0 - 30%, aluminum powder: 0 - 5%. The process formula of aluminum glue B is: oil-based polyurethane: 100%, adhesive: 0 - 10%, cyclized phosphate flame retardant: 0 - 20%, methyl ethyl ketone: 0 - 50%, aluminum powder: 5 - 10%. The aluminum glue coating 6 can well reflect high-temperature heat. At the same time, due to the increase in the thickness of the fabric behind the coating, the aluminum glue coating 6 can also well protect the flame-retardant fabric 4 from being damaged by thermal radiation and convective heat sources, enhancing the thermal protection performance.

[0021] Example Two

[0022] Combined with Figure 3 This embodiment will be described in detail. The difference from Example One is that the flame-retardant fabric 4 further includes a second flame-retardant layer 7, which is woven by polyimide double-strand yarns. Polyimide is a high-performance fiber with excellent thermal stability, and its limiting oxygen index is as high as 38%, with the characteristics of permanent flame retardancy, good high-temperature resistance and heat insulation performance, and is suitable for weaving flame-retardant and fire-proof fabrics.

[0023] Further, the flame-retardant fabric 4 further includes a heat insulation layer 8, and the heat insulation layer 8 is arranged between the first flame-retardant layer 5 and the second flame-retardant layer 7. The first flame-retardant layer 5, the heat insulation layer 8 and the second flame-retardant layer 7 are quilted and compounded together.

[0024] Further, the heat insulation layer 8 is aramid non-woven fabric or heat insulation cotton, which plays a role in blocking heat transfer.
