Description
Technical Field
The invention relates to the field of thermal protection, in particular to a special box body with efficient fireproof, heat-insulation and heat-preservation sealing functions.
Background
In some special fields, it is required that the sealed box body such as a carriage or a shelter has excellent performances of fire prevention, heat insulation and heat preservation, for example, when the periphery of the carriage or the shelter is subjected to external flame burning or a high-temperature environment, the temperature in the carriage or the shelter cannot exceed the maximum service temperature of internal electronic components or equipment within a specific time range.
In the prior art, materials with small apparent density, loose internal structure, high porosity and small water content are generally used as lightweight aggregates, and are combined together under the action of a binder and directly coated on the surface of equipment or a wall to form a heat-insulating layer with a certain thickness, so that the heat-insulating effect is achieved. Because the traditional heat insulation layer has a loose structure, the heat insulation performance of the traditional heat insulation layer is positively correlated with the thickness of the coating, so that the heat insulation layer needs to be very thick if the heat insulation effect is good; however, the increase of the thickness will cause the bonding strength of the coating and the substrate to be reduced, the coating is easy to fall off from the substrate, meanwhile, the increase of the thickness will cause the increase of the weight of the heat insulation layer, further the weight of the vehicle in the conventional state is influenced, the vehicle running is influenced, and the requirement of lightweight in the modern automobile industry is not met. Meanwhile, if the heat-insulating material in the prior art is adopted to be paved inside a carriage or a square cabin, and the fireproof temperature outside the carriage or the square cabin is usually over 1000 ℃ under special conditions, the thickness of the heat-insulating layer may need to be 80mm or even thicker, which obviously does not meet the requirement of modern industry on the coating of the carriage or the square cabin; in addition, when the limit working condition of a special vehicle or a shelter is met, for example, when the carriage or the shelter is covered by flame for a long time, the highest temperature of the carriage or the shelter already exceeds the service temperature range of the foam heat-insulating material, and if the conventional foam heat-insulating material is adopted for treatment, the foam heat-insulating material is combusted, melted or carbonized, so that the protective performance of the foam heat-insulating material is influenced, and even the internal safety performance of the foam heat-insulating material is influenced.
In the prior art, a stud is usually adopted to fix an interior trim panel, and the installation mode is that the stud is directly welded to a carriage or a shelter steel plate, and then the interior trim panel is directly installed on a screw extending from the surface of the carriage or the shelter steel plate; however, in this way, the stud is made of metal, so that the heat transfer efficiency is very high, and the surface temperature of the nut connected with the stud is too high, so that a large amount of heat is radiated to the interior decoration of the carriage or the square cabin by the high-temperature nut, and the overall thermal protection of the carriage or the square cabin is reduced. Meanwhile, the sealing structure of the door or the window of the traditional vehicle or the shelter has the defects that the sealing rubber strips are easy to damage by high temperature and generate gas passages, and heat is quickly transferred to the inner space of the vehicle or the shelter through the passages, so that the temperature of the inner space is quickly increased, the normal operation of internal electronic components, equipment and the like is influenced, and even fatal damage is generated to the equipment.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide a special box body with high-efficiency fireproof, heat-insulation and heat-preservation sealing functions, wherein the external anti-burning coating is very thin and only a few millimeters in thickness under the conventional state, and when the external anti-burning coating is burnt by flame, a heat-insulation layer with a compact structure can be quickly generated to realize fireproof and heat transfer blocking; the thickness of the internal heat insulation coating is small, the weight is low, and the heat insulation effect is good; meanwhile, the structure of the invention has good sealing performance, can effectively avoid the formation of a gas passage, can also effectively isolate the mounting stud from directly transferring heat to the internal environment, and improves the overall thermal protection performance in the cabin.

In the coating structure, the thickness of the anti-burning functional layer is thin under the conventional working condition, and the dehydrating agent, the carbon forming agent and the foaming agent in the anti-burning functional layer rapidly act under the firing of external flame to realize high-temperature expansion and carbonization to form a loose and porous foam carbonized heat insulation layer, so that the heat transfer is blocked, the purposes of fire prevention and high temperature prevention are realized, and the foaming multiplying power is 40-50 times; because the fireproof heat-insulating coating is instantly foamed, atomic groups and molecular groups in the components are mutually extruded in a short time, so that the porosity is high, and the fireproof and heat-insulating effects are good. After the anti-burning functional layer is burnt by flame to expand and carbonize, the coating can be locally peeled off and stripped due to the violent impact of flame airflow, and meanwhile, the anti-burning functional layer can also generate defects such as cracks and the like in the expansion process; these locations can become points of weakness in the insulation, affecting the overall insulation of the shelter. The structure of the invention is used for heat insulation of weak points of heat insulation through the combination of the heat insulation functional layer and the burning-resistant functional layer and the matching relationship of the film object a and the film object b, and simultaneously prevents the phenomenon that the burning-resistant functional layer is locally dropped because the bonding strength of the burning-resistant functional layer is reduced due to the increase of the thickness of the burning-resistant functional layer during high-temperature carbonization. Simultaneously, thermal-insulated functional layer also provides thermal-insulated function under the conventional environment for the shelter, prevents because of under the circumstances such as the direct solar radiation, heat transfer to the shelter body, promotes the whole thermal protection performance of shelter. Through the structural combination of the high-reflection layer and the thermal resistance layer, namely the alternate superposition of the reflection screen and the heat insulation material, the reflection layer has a high reflection effect on heat radiation rays, and heat is isolated by reflecting the transmitted heat radiation; the thermal resistance layer has a low thermal conductivity coefficient, which can suppress the transmitted thermal radiation; through the lamination and compounding, the convection heat transfer is reduced, and the heat insulation are realized. Meanwhile, the structure combination of the high-temperature-resistant heat-insulating layer and the low-heat-conduction heat-insulating layer is adopted, so that the density of the inner-wall heat-insulating layer is kept at a proper value, the thickness of the heat-insulating layer is effectively reduced, and the overall low weight of the heat-insulating layer is ensured.

Among the above-mentioned interior trim installation fastening structure, keep apart interior plaque and screw rod, prevent that the heat direct transfer of screw rod gathering under the extreme condition from leading to interior plaque's heat rising, influence the inside holistic heat protection of shelter.
