Abstract
Provided is a fire-proof trough box capable of resisting hydrocarbon (HC) fire disaster. A fire-proof layer of the fire-proof trough box comprises a fold-insulation layer, a thermal expansion layer and a heat-insulation layer in sequence from outside to inside, wherein cloth-shaped fire-proof materials are folded and then sewn up to form the structure of the fold-insulation layer. A suture line can be burnt out when meeting fire because an outermost layer is sewn up, and thereby an inflating space is reserved for inner thermal expansion. The fire-proof trough box not only is high in fire-proof limitation of resisting HC fire disaster and excellent in fire-proof effect, but also can prevent the inner structure of the fire-proof trough box from being affected by high temperature.
Description
Technical field
The present invention relates to a kind of fire-resistant groove box, belong to the fire proofing material field.
Background technology
To different combustibles and burning-point, fire can be divided into different grade.If ordinary combustible such as fiber and lignin is according to the burning of standard heating curve, it can be warming up to 1000 ℃ in 90min; If the breaking out of fire owing to the damage of mechanical seal of petroleum chemical enterprise or hot oil pump, then mostly its combustible is pure CH compound, belongs to hydrocarbon fire, and it heats up sooner, flame is more fierce, in 6min, can be warming up to 1000 ℃.
In addition, for different buildings and place, also be different for the requirement of the fire protecting performance of fire proofing material.Large scale industry facility for petroleum chemical enterprise, nuclear energy power plant, military installations etc.; Its inner back-up system need can guarantee that under hydrocarbon fire 3 hours water, gas and electricities are continuous; Particularly, require its surperficial fire proofing material in fire, can realize following four requirement of shelter usually for fire-resistant groove box:
1, guarantees that its inner fire-resistant groove box does not cut off the power supply in hydrocarbon fire burnt 3 hours;
2, removing its inner fire-resistant groove box of fire proofing material behind the fire can continue to use;
3, size is thin as far as possible, saves the space;
Can be heat insulation when 4, resisting fire.
Therefore conventional fireproof paint obviously can not satisfy in the hydrocarbon fire the protection requirement of fire-resistant groove box, is badly in need of that exploitation is a kind of can to realize in the hydrocarbon fire fire proofing material of fire-resistant groove box in the fire-resistant groove box of protection.
The utility model content
Can't in hydrocarbon fire, effectively protect the problem of fire-resistant groove box in order to solve general fire proofing material, the utility model provides a kind of fire-resistant groove box of resisting hydrocarbon fire.
A kind of fire-resistant groove box of resisting hydrocarbon fire is characterized in that its surperficial fireprotection layer ecto-entad comprises folding heat-insulation layer, thermal expansion layer, thermal insulation layer successively, and said folding heat-insulation layer is the folding structure of sewing up again of cloth shape fire proofing material.
Said folding heat-insulation layer is the aluminium foil cloth material.
Said aluminium foil cloth is the structure that first doubling is sewed up the edge of the formation after the doubling again.
Said thermal expansion layer is that polyurethane-coated is processed in base material.
Said thermal insulation layer is the nano material of coefficient of heat insulation below 0.05.
A kind of fire-resistant groove box of resisting hydrocarbon fire of the utility model; Its fireprotection layer is made up of three-decker, and what play central role is the thermal expansion layer of the second layer, and its coating is preferably PU; That under peacetime state, can make is thinner; Be suitable as the external protection of fire-resistant groove box, when breaking out of fire, meet fire expansion formation carbonization froth bed rapidly, play good isolated flame and heat insulation effect.Its inside is one deck thermal insulation layer, selects the coefficient of heat insulation materials with smaller for use, and the inner electric wire surface of fire-resistant groove box can be above 100 ℃ when further guaranteeing to issue licence hydrocarbon fire.Outermost layer is owing to form for sewing up, and suture can be blown when meeting fire, reserves the space of expansion can for so inner thermal expansion layer.
The utility model is the fire endurance height of anti-hydrocarbon fire not only; Flameproof effect is excellent, can also protect its internal structure not receive temperatures involved, and that the three range upon range of structures that add had both been processed was easy, manufacturing cost is low; Can guarantee the unification of volume and flameproof effect again fully, therefore have a good application prospect.
Description of drawings
Fig. 1 is a kind of fire-resistant groove box schematic cross-section of resisting hydrocarbon fire of the utility model.
Each label is listed as follows among the figure:
The fire-resistant groove box of 1-, the 2-thermal insulation layer, the 3-thermal expansion layer, 4-folds heat-insulation layer.
Embodiment
The utility model is further described the utility model in order better to explain below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, resist the schematic cross-section of embodiment of the fire-resistant groove box of hydrocarbon fire for the utility model is a kind of, ecto-entad is followed successively by folding heat-insulation layer 4, thermal expansion layer 3, the thermal insulation layer 2 of aluminium foil cloth.
The folding heat-insulation layer 4 of said aluminium foil cloth material is for forming sewing up after the doubling of one deck aluminium foil cloth again, and suture can be blown when meeting fire, reserves the space of expansion can for so inner thermal expansion layer.
Said thermal expansion layer is that polyurethane-coated is processed in base material, when high temperature, can smokeless rapidly carbonization expand, and forms the carbonization froth bed, and isolated flame plays fire-retardant effect.
Said thermal insulation layer employing coefficient of heat insulation is 0.05 nanometer heat insulation material, guarantees that the surface of insulating layer of internal refractory groove box 1 can not surpass 100 ℃, make fire-resistant groove box 1 after removing the surface fireproof material behind the fire, still can continue to use.
Through the test of anti-hydrocarbon fire, the anti-hydrocarbon fire time of present embodiment is 3.5h, has reached the requirement of resisting hydrocarbon fire.
Claims (5)
