Detailed Description

The utility model will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present utility model and are not intended to limit the scope of the present utility model.

The utility model relates to a novel fireproof layer, which comprises a main structure and a heat insulation layer 2, wherein a separation piece 3 is arranged between the flame retardant layer 1 and the heat insulation layer 2 in a matched manner, and the flame retardant layer 1 and the heat insulation layer 2 are separated and matched in a non-contact manner through the separation piece 3.

The specific arrangement of the flame retardant layer 1 and the heat insulating layer 2 provided as described above is as follows:

for the arrangement of the flame retardant layer 1: the ceramic fiber has good high temperature resistance. In general, they also have good heat-insulating properties at a high temperature of 1500℃under certain conditions. The heat insulating capability is a special property of ceramic fibers compared with other fibers, and the good heat insulating property of ceramic fibers mainly comes from the mixed structure of ceramic fibers, namely solid fibers and air composition. In addition, the ceramic fiber has good toughness which is not possessed by other refractory materials, and the ceramic fiber is widely used in industrial furnace walls and building materials due to the heat insulation performance of the ceramic fiber. Meanwhile, the metal aluminum foil coated on the outer layer of the ceramic fiber can effectively reflect the radiated heat, so that combustion is effectively prevented.

For the arrangement of the insulating layer 2: the pre-oxidized fiber felt has high flame retardance, limiting oxygen index higher than 45%, and better heat stability than other fiber felts, and the fiber felt is not melted, softened and contracted and has no molten drop phenomenon when being burnt at high temperature, thus the pre-oxidized fiber felt belongs to a quasi-incombustible product. The pre-oxidized fiber felt has good heat insulation performance and can effectively insulate the heat of the outer layer. In addition, the material has very good acid and alkali corrosion resistance, chemical environment resistance and radiation resistance. The textile processing cost is low, and the internal fabric is light in weight, soft and good in water absorption performance. The insulating layer 2 fabric comprises a multi-layer combined fabric formed by pre-oxidized fiber felts, and the TPP value of the multi-layer combined fabric is larger than that of other types of insulating felts. Therefore, the pre-oxidized fiber is a novel special material with heat resistance and flame resistance, and has good heat protection performance.

The specific arrangement of the spacers 3 provided as described above is as follows:

because in the setting of many flame retardant coating surface fabrics, whether sewing mode is also good or use other modes to connect also good, all need to carry out effective connection between flame retardant coating 1 and the interlayer to after connecting flame retardant coating 1 and insulating layer 2, can not exist the space clearance between flame retardant coating 1 and the insulating layer 2 any longer, so that after flame retardant coating 1 absorbs heat, can directly transmit the heat for insulating layer 2, and then make insulating layer 2 appear the phenomenon of rising temperature very fast. And for the mode of the laminating connection of flame retardant coating 1 and insulating layer 2, also be inconvenient in the heat dissipation process and dispel the heat to influence the application of flame retardant coating under actual environment.

Therefore, the above-mentioned setting of the spacer 3 between the flame retardant layer 1 and the heat insulating layer 2 makes the separation between the flame retardant layer 1 and the heat insulating layer 2 fit without contact after the setting of the spacer 3, and further makes there be a gap between the flame retardant layer 1 and the heat insulating layer 2, when the flame retardant layer 1 absorbs heat to raise its temperature and transfer heat, it is first necessary to heat the gap air between the flame retardant layer 1 and the heat insulating layer 2, and after the air absorbs heat, transfer heat to the flame retardant layer 1, and raise the temperature of the flame retardant layer 1. For the isolating piece 3 arranged in the position, materials with good high temperature resistance and heat insulation performance are selected for arrangement, so that the isolating piece 3 can play a good role in heat insulation and heat absorption, and accordingly rapid heat transfer between fireproof layers is avoided, and better time is given to evacuees or rescue workers.

The specific structure of the spacer 3 is set: the spacer 3 is a supporting spacer structure.

Firstly, the supporting and isolating structure is an isolating net 4, and the isolating net 4 is paved and arranged at the position between the flame-retardant layer 1 and the heat-insulating layer 2, so that the flame-retardant layer 1 and the heat-insulating layer 2 are not contacted with each other. The mode that sets up is laid between fire-retardant layer 1 and insulating layer 2 with the spacer grid 4 can ensure through spacer grid 4, carries out more abundant isolation to fire-retardant layer 1 and insulating layer 2 to it is more convenient to carry out processing production when setting up. In terms of the material selection of the isolation net 4, the isolation net 4 is made of a bendable and deformable material, so that normal movement of a user is not affected after the isolation net 4 is arranged, and normal use of the user is prevented.

Secondly, the supporting isolation structure is a supporting end 5, and a plurality of supporting ends 5 are arranged at the positions between the flame-retardant layer 1 and the heat-insulating layer 2 at equal intervals, so that the distance between the flame-retardant layer 1 and the heat-insulating layer 2 is limited. The manner of setting the support ends 5 is troublesome in the production and processing, and the support ends 5 need to be set one by one, but after the support ends 5 are installed, the problem of wrinkling between the heat insulating layer 2 and the flame retardant layer 1 does not occur, which is important. Because if the heat insulation layer 2 is wrinkled, the problem that the heat resistance degree of each position of the fireproof layer is inconsistent is easily caused, thereby affecting the effect of the fireproof layer for isolating flames as a whole.

Further, the heat insulation layer further comprises a ventilation waterproof layer 6, wherein the ventilation waterproof layer 6 is arranged at the inner layer position of the fireproof layer and is connected with the heat insulation layer 2. The polytetrafluoroethylene film (PTFE) is a polymer material prepared by a biaxial stretching process, the microstructure of the PTFE is characterized in that criss-cross fiber filaments are connected with each other under an electron microscope, and micropores of the PTFE film are formed by tiny gaps among the fiber filaments. The most abundant polytetrafluoroethylene is the C-F bond, which has a higher electronegativity and thus a greater polarity. In the C-F bond, the F atom is able to attract more covalent electron pairs than the other bonds. On the other hand, the fluorine atoms are larger in the overall structural volume and mutually exclusive, the macromolecular chains are in a spiral shape, and the fluorine atoms on the main chain have better symmetry. Polytetrafluoroethylene has better stability when being at high temperature. The temperature range for its normal use is-190 ℃ to 260 ℃. The polytetrafluoroethylene had a melting point of 327℃and a temperature at which thermal decomposition took place of 420 ℃. This characteristic is superior in heat resistance to existing engineering plastics. When the temperature exceeds 420 ℃, the mass of the decomposition per hour thereof is about 0.01% of the total mass. In conclusion, polytetrafluoroethylene has wide application space in high-temperature operation. The diameter range of the micropores of the polytetrafluoroethylene film is mainly 0.8-1 mu m, the minimum diameter of the micropores of the polytetrafluoroethylene film can be 0.6 mu m, and even if the maximum pore diameter exists, the diameter is only about 1.6 mu m, so that water vapor with the diameter of about 0.0004 mu m can pass through the micropores of the polytetrafluoroethylene film but liquid water with the diameter of 20 mu m can not pass through the micropores, and the polytetrafluoroethylene film has good waterproof and moisture permeability.

Furthermore, an inner lining layer is arranged in cooperation with the breathable waterproof layer 6, the inner lining layer is made of soft materials, the inner lining layer is required to have softness and comfort, and good moisture absorption and ventilation capabilities are required to be sewn together with the heat insulation layer 2. In general, common materials of manufacture are: the viscose and the pure cotton are subjected to flame retardant treatment and the like.

A novel fireproof layer fireproof suit is applied to the novel fireproof layer.

After the fireproof layer is used for preparing the fireproof clothes, the fireproof clothes have good heat resistance and fireproof performance. Mainly, in the setting of fire-proof clothing here, including clothing body 7, traction portion 8 is high temperature resistant tensile material, just traction portion 8 is connected with fire-retardant layer 1, insulating layer 2 between the barrier 3.

Because fire-proof clothing is also very important for emergency rescue, namely under the condition that the user loses the mobility, need ensure that fire-proof clothing possesses fine tensile properties, consequently carry out the setting of traction portion 8 here, and select high temperature resistant tensile material as traction portion 8 to set up to realize better tensile properties. Because the pulling part 8 is connected to the spacer 3 here, it is also necessary that the spacer 3 has a good traction resistance when the fire-resistant layer is used for the production of fire-resistant clothing. The above-mentioned support head 5 is thus provided as a spacer 3, which is more capable of meeting traction requirements.

Furthermore, an asbestos net is arranged on the outer side of the traction part 8, and the traction part 8 is surrounded by the asbestos net so as to achieve the purpose of burn resistance.

Further, a zipper opening position is formed in the clothes body 7, the traction portion 8 is detachably arranged inside the zipper opening position, and the traction portion 8 can be conveniently hidden when the traction portion 8 is not used.

Therefore, the novel fireproof layer and the fireproof garment applying the same can ensure that a user can provide proper protection for firefighters or evacuees in the application of real fire conditions so as to ensure that the fireproof layer can adapt to the environmental requirement of rapidly spreading the fire conditions, thereby striving for the most precious escape time or rescue time for the user.
