High temperature resistant fireproof cloth

Technical Field

The utility model relates to a fireproof cloth, in particular to a high-temperature-resistant fireproof cloth.

Background

In recent years, the frequent occurrence of fire greatly threatens the life and property safety and the quality of life of people, so the research and development of fire-extinguishing rescue equipment become the focus of research of researchers. The firefighter uniform is a protective garment worn by firefighters under radiation and heat infringement when the firefighters put out a fire and rescue a disaster and are close to a disaster area, and the firefighters can maximally guarantee the first line and fire fighting. In the fire-fighting operation, the advantages and disadvantages of the individual protective clothing directly influence the fighting efficiency of the firefighter, the functions are complete, the fighting capacity of the firefighter can be greatly improved by the firefighter wearing the comfortable firefighter clothing, and the life safety of the firefighter is guaranteed.

The existing firefighter uniform is generally formed by compounding an outer layer, a heat insulation layer and a comfort layer. The outer layer is typically an aluminum coating material that reflects high temperature radiation, prevents heat from projecting into the inner layer, and prevents the firefighter uniform from spontaneous combustion. The heat-insulating layer is generally made of polytetrafluoroethylene plastic, and the material can endure high temperature of 250 ℃ without deformation and expansion, and can endure the attack of various strong acids and strong bases. The comfort layer is also the part closest to the human body and is used for isolating the human body from heat absorbed by the firefighter uniform, and the part used for thermal insulation is generally flame-retardant fibers which are not only high-temperature resistant, but also can further prevent heat transfer after being carbonized.

Aerogel is a nano-scale porous solid phase material formed by replacing liquid phase in gel with gas by certain drying method through sol-gel method, and is called the lightest solid in the world, also called "blue smoke". The silicon dioxide aerogel is a light nano porous amorphous solid material with excellent heat-proof and heat-insulating properties, the porosity of the material is as high as 80-99.8%, the size of the pores is 1-100nm, and the specific surface area is 200-²A density of as low as 3kg/m³The room temperature thermal conductivity can be as low as 0.012W/(m.k). The existing firefighter uniform is not satisfactory in the aspects of heat insulation and high temperature resistance, and the safety of firefighters cannot be guaranteed comprehensively, so that the problem is solved by using the firefighter uniform added with silica aerogel cloth.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

As shown in fig. 1, a high temperature resistant fireproof fabric comprises a reflective layer, a wear-resistant layer, a waterproof breathable layer, a flame-retardant layer, a heat-insulating layer, and a comfortable layer. The reflective coating is characterized in that a wear-resistant layer is fixed on one side of the reflective layer, a waterproof breathable layer is arranged on one side of the wear-resistant layer, a flame-retardant layer is connected to one side of the waterproof breathable layer, a heat-insulating layer is fixed on one side of the flame-retardant layer, and a comfortable layer is arranged on one side of the heat-insulating layer. The reflecting layer is formed by aluminum foil composite base cloth, and the base cloth is mainly made of glass fiber fabric; the aluminum foil base cloth is formed by hot-pressing and compounding high-temperature-resistant glue, and the thickness of the aluminum foil base cloth is 1-5 mm. The wear-resistant layer is made of nylon. The waterproof breathable layer is made of polytetrafluoroethylene. The flame-retardant layer is composed of nano silicon dioxide aerogel, the thickness of the flame-retardant layer is 3-5 mm, and the melting point of the flame-retardant layer is above 1300 ℃. The thermal insulation layer is formed by blending aramid 1313 and flame-retardant cotton fibers by a method comprising the following steps of: 35 in proportion. The comfortable layer is formed by blending modacrylic and flame-retardant viscose.

The working principle of the utility model is as follows: when the fire fighter wears this high temperature resistant fire prevention cloth, reflection stratum 1 at first contacts with the external world, and aluminium foil base cloth can reflect most heat in the scene of a fire as first defence line. When the reflecting layer 1 is broken, the nylon cloth of the wear-resistant layer 2 can exert the wear-resistant characteristic, and other protective layers in the cloth are prevented from being worn. When the firemen meet the dangerous condition, need rescue in the scene of a fire for a long time and then lead to wearing layer also to appear damaged, waterproof ventilative layer 3 begins the part to expose in the air and undertakes important protection work this moment. The polytetrafluoroethylene can isolate high-temperature radiation in a fire scene and protect strong acid and strong alkali solution splashed in the fire scene, so that the life safety of firemen is prevented from being damaged. When extreme conditions occur, the firefighter needs to enter the center of the fire source to withstand the central temperature of the flame up to thousands of degrees, the polytetrafluoroethylene cannot sufficiently protect the safety of the firefighter. At this time, the silica aerogel of the flame-retardant layer 4 shows extremely good fireproof characteristics due to its extremely low thermal conductivity, up to a melting point of 1300 ℃. The silica aerogel can not be spontaneously combusted, can not conduct a large amount of heat, and can comprehensively ensure the safety of firemen in a high-temperature fire scene. The heat source finally reaching the heat insulation layer 5 through layer-by-layer protection is further weakened and isolated through the action of the aramid fiber 1313 and the flame-retardant cotton fiber blended fabric. The comfortable layer 6 ensures the comfort of the firefighter wearing body.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
