A special box with high-efficiency fire prevention, heat insulation, heat preservation and sealing functions

Abstract

The invention discloses a special box with high-efficiency fireproof, heat-insulating, heat-preserving and sealing functions, which is composed of a coating structure, an interior decoration installation and fastening structure, a cabin door and a window sealing structure; wherein, the coating structure is composed of a square From the outside to the inside of the cabin, there are fireproof heat insulation layer (1), shelter body steel plate (2), and heat insulation layer (3); the inner wall surface of the cabin with fastening structure for the interior decoration is inwardly followed by the shelter body steel plate (2), thermal insulation layer (3), interior installation substrate (4), interior trim panel (5); the hatch door and window sealing structure consists of the shelter frame (6), the shelter tail post (7) , the shelter tailgate (8), the first sealing structure (91), the second sealing structure (92), the third sealing structure (93), and the heat insulation layer (3). The structure has good heat insulation effect and good sealing performance; it can ensure the normal operation of the facilities and equipment inside the cabin under fire, high temperature and other conditions.

Description

technical field [0001] The invention relates to the field of thermal protection, in particular to a special box with high-efficiency fire prevention, heat insulation, heat preservation and sealing functions. Background technique [0002] In some special fields, sealed boxes such as carriages or shelters are required to have excellent performances such as fire protection, heat insulation and heat preservation. The temperature in the shelter cannot exceed the maximum operating temperature of the internal electronic components or equipment. [0003] Heat insulation coatings in the prior art usually use materials with low apparent density, loose internal structure, high porosity, and low moisture content as lightweight aggregates, which are bonded together by binders and directly applied to equipment or walls. A thermal insulation layer with a certain thickness is formed on the surface of the body, so as to achieve the effect of heat insulation. Due to the loose structure of t...

AI Technical Summary

Problems solved by technology

Due to the loose structure of the traditional heat insulation layer, its heat insulation performance is positively related to the thickness of the coating. Therefore, if the heat insulation effect is to be good, the heat insulation layer must be very thick; but the increase of the thickness will lead to the gap between the coating and the substrate. The bond strength decreases, and the coating is easy to fall off from the substrate. At the same time, the increase in thickness will lead to an increase in the weight of the heat insulation layer, which will affect the weight of the vehicle under normal conditions and affect the driving of the vehicle. It does not meet the lightweight requirements of the modern automobile industry.

At the same time, if heat insulation materials in the prior art are used to lay inside the carriage or shelter, and the fireproof temperature outside the carriage or shelter is usually above 1000°C under special circumstances, the thickness of the heat insulation layer may need to be 80mm or even thicker. , which obviously does not meet the requirements of modern industry for the coating of carriages or shelters; and, for the extreme working conditions of special vehicles or shelters, such as when the carriages or shelters are covered by flames for a long time, the coating of the compartments or shelters The maximum temperature has already exceeded the operating temperature range of foam insulation materials. If traditional foam insulation materials are used for treatment, foam insulation materials will burn, melt or carbonize, thereby affecting their protective performance and even affecting internal safety performance.

[0004] In the prior art, studs are usually used to fix the interior panels. The installation method is to directly weld the studs to the steel plates of the carriage or shelter, and then directly install the interior panels on the screws extending from the surface of the steel plates of the carriage or shelter. ; But in this way, because the studs are made of metal, the heat transfer efficiency is very high, so that the surface temperature of the nuts connected to them is too high, so that the position of the high-temperature nuts will radiate a large amount of heat to the interior of the compartment or shelter, reducing the temperature of the compartment or shelter. overall thermal protection

At the same time, there are sealing strips in the sealing structure of the door or window of the traditional vehicle or shelter, which are easily damaged by high temperature and generate gas passages. The heat will be quickly transferred to the internal space of the vehicle or shelter through these passages, causing the temperature of the internal space to rise rapidly. , thereby affecting the normal operation of internal electronic components, equipment, etc., and even causing fatal damage to these equipment
