Abstract
The invention discloses a steel fireproof door internally provided with a fireproof material. The steel fireproof door comprises a steel door body. The front face and the back face of the steel door body are both provided with a refrigerating cavity. Dry ice is injected into the refrigerating cavities. Pressure valves are arranged on the tops of the refrigerating cavities, injection openings are formed in the bottoms of the refrigerating cavities, and a fireproof glass layer and a fireproof tender porcelain layer are arranged between the refrigerating cavities. According to the steel fireproof door internally provided with the fireproof material, due to the fact that the refrigerating cavities are arranged and the dry ice is injected into the refrigerating cavities, during a fire disaster, the dry ice is heated to sublimate, and generated high-pressure gas bursts the pressure valves; due to the fact that a large amount of heat needs to be absorbed when the dry ice sublimates and the heat is exhausted into the external environment along with the gas, the test of big fire can be well tolerated; after arranged injection type fireproof glass encounters high temperature, a transparent jelly-shaped fireproof glue layer between the glass can be rapidly hardened, an opaque fireproof heat insulating plate is formed, and high temperature is prevented from being transmitted to a side unexposed to fire while flames are prevented from spreading.
Description
Technical field
The invention belongs to fire resistant doorsets technical field, and in particular to a kind of steel-made fire-retardant door of built-in fire proofing material.
Background technology
Fire resistant doorsets refer to the door that can meet the requirement of fire stability, integrality and thermal insulation within a certain period of time.The fire separation things with certain fire resistance such as it is between being located at fire compartment, emergency staircase, vertical shaft.Fire resistant doorsets, with more the effect for preventing fire spreading and flue gas diffusion, can within a certain period of time prevent spreading for the intensity of a fire, it is ensured that evacuating personnel in addition to the effect with common door.Current fire resistant doorsets are preferable not to the utmost in use, can not well intercept spreading for the intensity of a fire, it is impossible to the need for meeting use.
The content of the invention
It is an object of the invention to provide a kind of steel-made fire-retardant door of built-in fire proofing material, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of steel-made fire-retardant door of built-in fire proofing material, including steel door body, the front and back of the steel door body is equipped with refrigeration cavity, the inside of the refrigeration cavity is marked with dry ice, pressure valve is provided with the top of the refrigeration cavity, the bottom of the refrigeration cavity is provided with inlet, and fireproof glass layers and fire prevention porcelain tendre layer are provided between the refrigeration cavity.
Preferably, the fireproof glass layers are made up of composite fireproof glass, pouring type flame resistant glass and wired flame resistant glass, the composite fireproof glass is composited by least layer glass original piece by water-soluble inorganic fireproof gum interlayer, the pouring type flame resistant glass is made up of layer glass original piece, and surrounding is sealed with special flame-retardant rubber strip, centre perfusion fire prevention glue, the layer glass of the wired flame resistant glass forms interlayer, wire is provided with the interlayer by inorganic adhesive.
Preferably, refractory mineral matter filler and fire retardant fire-proof additive are filled with the fire prevention porcelain tendre, the refractory mineral matter filler has alumina powder, calcium carbonate granule and perlite particle, and the fire retardant fire-proof additive has chlorinated paraffin, tributyl phosphate and aluminium borate.
Technique effect of the invention and advantage：The steel-made fire-retardant door of the built-in fire proofing material is due to being provided with refrigeration cavity, and inject dry ice in the cavity that freezes, when catching fire, dry ice receives heat sublimation, the gases at high pressure burst pressure valve of generation, because dry ice sublimation needs to absorb substantial amounts of heat, and heat is entered in external environment with gas, can be very good to withstand the test of big fire；After high temperature is met, the gelatin fire prevention glue-line of glass central, clear can harden rapidly the pouring type flame resistant glass of setting, form an opaque fire-proof heat insulation board, while propagation of flame is prevented, also prevent high temperature from supporting or opposing the conduction of fiery face；The composite fireproof glass of setting, when fire occurs, side towards the fire glass bursts quickly after meeting high temperature, ten times or so of the successive foaming and intumescing of its fireproof gum interlayer, forms hard milky blister Formica, effectively blocks flame, completely cuts off high temperature and pernicious gas；The wired flame resistant glass for setting, the woven wire of middle setting can improve the overall impact strength of flame resistant glass.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure：1 steel door body, 2 refrigeration cavitys, 3 fire prevention porcelain tendre layers, 4 fireproof glass layers, 41 composite fireproof glass, 42 pouring type flame resistant glasses, the pressure valve of 43 wired flame resistant glass 5,6 inlets.
