Description
Technical Field
The invention relates to the field of individual protective equipment, in particular to a fireproof fabric and fire-resistant clothes using the same.
Background
The fire-protection suit is a protective suit worn by firefighters when entering a fire scene to fight off malignant fire and rescue, and is a special protective suit for protecting the whole body of the firefighters from fire. In fire rescue, a fireman can approach a fire area only by wearing the fire-protecting suit, and is invaded by strong radiant heat when approaching flames, so that the fire-protecting suit needs to have strong heat insulation, high temperature resistance, flame retardance and other performances in order to ensure the safety of the fireman.
The traditional fire-resistant suit consists of a surface layer coated with aluminum foil, a waterproof breathable layer, a heat-insulating layer and a comfortable lining sequentially from outside to inside, and a firefighter wearing the suit can only pass through a fire scene in a very short time to rescue. In the related art, for example, publication No. CN201110048233.5 discloses a fire-fighting fire-proof suit capable of reducing temperature and prolonging rescue time in fire sea, the fire-proof suit body is composed of a fire-resistant cloth layer, a heat-insulating cloth layer, a waterproof cloth layer, a grid temperature-reducing layer capable of being provided with a temperature-reducing heat-absorbing material and a comfortable cloth layer which are sequentially overlapped. Before use, the lattice cooling layer with heat absorbing material is cold stored in refrigerator, and the zipper is opened to place the cooling layer in the corresponding part of the clothing. The patent adds a heat-absorbing and cooling layer on the basis of the traditional fire-proof clothes, theoretically, the cooling layer can absorb partial heat to make people feel more comfortable, but the implementation of the heat-absorbing and cooling layer has great problems, one is that the fire-proof clothes are thicker and heavier, and the increase of the cooling layer can increase the load of a wearer and influence the mobility of the wearer; secondly, the cooling and heat absorbing material needs to be put into a freezer in advance for cold storage, so that much time cost and material cost are increased; thirdly, the wearing cost of the fire-proof clothes is complex, and the assembling and disassembling mode of the cooling layer increases the whole wearing difficulty of the clothes. And fire-protection clothes in the related art can only pass through a fire scene in a short time to carry out rescue, and are not enough in heat insulation, not good in comfort level, difficult to process and difficult to realize standardized mass production.
Therefore, it is necessary to provide a new fire-proof cloth and a fire-protecting suit using the same to solve the above problems.
Disclosure of Invention
The fire-protection suit aiming at the related art can increase the negative ghost noise mobility of a wearer due to the fact that the fire-protection suit is thick and heavy, and has the advantages of being large in wearing/detaching difficulty, insufficient in heat insulation performance, difficult to process, incapable of achieving standardized mass production and the like. The invention provides the fireproof cloth which is light and convenient and has a good fireproof effect.
The utility model provides a fireproof cloth, its includes the fire prevention skin, thermal-insulated middle level and the comfortable inlayer that stack gradually the setting, wherein:
the fireproof outer layer comprises a blended layer and a fireproof layer fixedly arranged on the outer side of the blended layer;
the heat insulation middle layer comprises a heat insulation main layer and a waterproof breathable layer fixedly arranged on the heat insulation main layer;
the comfortable inner layer is of a wave-shaped structure, one part of the comfortable inner layer is fixedly attached to the waterproof breathable layer, and the other part of the comfortable inner layer and the waterproof breathable layer are arranged at intervals to form an air layer for accommodating air.
Preferably, the blending layer is formed by blending pre-oxidized fibers and para-aramid fibers.
Preferably, the blended layer is formed by blending 70% of pre-oxidized silk and 30% of para-aramid.
Preferably, the fireproof layer is an aluminum foil, and the blended layer is attached to the aluminum foil through a flame-retardant adhesive to form the fireproof outer layer.
Preferably, the heat insulation main layer is made of aerogel and reinforced fibers in a composite mode.
Preferably, the aerogel is a nano-cellulose aerogel, and the reinforcing fiber is glass fiber or pre-oxidized fiber.
Preferably, the waterproof breathable layer is made of aramid non-woven fabric coated with a flame-retardant PTFE film.
Preferably, the waterproof breathable layer is provided with two layers, and the two layers of waterproof breathable layers are respectively positioned on two opposite sides of the heat insulation main layer.
Preferably, the comfortable inner layer is formed by blending the phase change energy storage fibers and the aramid fibers.
The fire-preventing clothes are made of the fireproof fabric.
Compared with the prior art, the fireproof cloth provided by the invention adopts a three-layer combination mode of the fireproof outer layer, the heat insulation middle layer and the comfortable inner layer, is reasonable in design and light in weight, and can realize standardized mass production; and comfortable inlayer is the wave structure, and the wave structure forms the air bed that holds the air, and the wearing person is comfortable and the temperature regulation performance is showing, can effectively promote fire prevention effect through fire prevention outer, thermal-insulated middle level and comfortable inlayer three layer construction, extension scene of a fire rescue time.
The heat insulation main layer in the heat insulation middle layer adopts cellulose aerogel which has extremely low heat conductivity coefficient and can effectively improve the whole heat insulation effect; and the comfortable inner layer is made of the phase-change material and is matched with the wavy structure of the comfortable layer, so that the comfortable inner layer has the characteristics of uniform dispersion and remarkable temperature regulation performance.
Correspondingly, the suit of keeping away fire in this application provides the thermal-insulated respond well of fire prevention cloth through adopting this application, can effectively prolong fire fighter scene of a fire rescue time to it is little to dress the degree of difficulty, and light also can reduce fire fighter's heavy burden of weight, saves physical power, and simple structure can realize standardized volume production simultaneously.
