Abstract
The utility model discloses a fire door is prevented to built -in fire -proof material's steel, including the steel door body, the front and the back of the steel door body all are equipped with the refrigeration cavity, the inside notes of refrigeration cavity has dry ice, the top of refrigeration cavity is equipped with the pressure valve, the bottom of refrigeration cavity is equipped with the filling opening, be equipped with fire prevention glass layer and fire prevention soft porcelain layer between the refrigeration cavity. This fire door is prevented to built -in fire -proof material's steel has been owing to set up the refrigeration cavity, and injects dry ice into in the refrigeration cavity, and when catching fire, dry ice receives the heat sublimation, the high -pressure gas bursting pressure valve of formation, because dry ice distillation needs to absorb a large amount of heats, and the heat is followed during gas enters external environment, the test that withstands the big fire that can be fine, the type that the pours into fire prevention glass who sets up is after meeting high temperature, and the fire prevention glue film scleroma rapidly of transparent jelly form in the middle of the glass forms an opaque fire prevention heat insulating board, when stoping flame spread, also stops high temperature to support or oppose the fire face and conducts.
Description
Technical field
The utility model belongs to fire door technical field, is specifically related to the steel-made fire-retardant door of a kind of built-in fire-retardant material.
Background technology
Fire door refers to the door that can meet fire-resistant stability, integrity and thermal insulation within a certain period of time and require. It is located between fire compartment, fire-resisting division thing that emergency staircase, vertical vertical shaft etc. have certain resistivity against fire. Fire door, except the effect with common door, has more the effect stoping fire spreading and Flue Gas Diffusion, can stop spreading of the intensity of a fire within a certain period of time, it is ensured that evacuating personnel. Current fire door is in use desirable not to the utmost, can not well intercept spreading of the intensity of a fire, can not meet the needs of use.
Practical novel content
The purpose of this utility model is to provide the steel-made fire-retardant door of a kind of built-in fire-retardant material, to solve in above-mentioned background technology the problem proposed.
For achieving the above object, the utility model provides following technical scheme: the steel-made fire-retardant door of a kind of built-in fire-retardant material, comprise steel door body, the front and back of described steel door body is equipped with refrigeration cavity, the inside of described refrigeration cavity is marked with dry ice, the top of described refrigeration cavity is provided with pressure valve, and the bottom of described refrigeration cavity is provided with inlet, is provided with flame resistant glass layer and the soft porcelain layer of fire prevention between described refrigeration cavity.
Preferably, described flame resistant glass layer is made up of composite fireproof glass, pouring type flame resistant glass and wired flame resistant glass, described composite fireproof glass is composited by water-soluble inorganic fire prevention glue interlayer by former of at least layer glass, described pouring type flame resistant glass is made up of former of layer glass, and surrounding seals with special flame-retardant rubber strip, middle perfusion fire prevention glue liquid, the layer glass of described wired flame resistant glass forms interlayer by inorganic adhesive, is provided with wire in described interlayer.
Preferably, the soft porcelain of described fire prevention is filled with refractory mineral matter filler and difficult combustion fire-proof additive, described refractory mineral matter filler has alumina powder, calcium carbonate granule and perlite particle, and described difficulty combustion fire-proof additive has clorafin, tributyl phosphate and aluminum borate.
Technique effect of the present utility model and advantage: the steel-made fire-retardant door of this built-in fire-retardant material is owing to being provided with refrigeration cavity, and inject dry ice in refrigeration cavity, when catching fire, dry ice is by heat sublimation, the high pressure gas burst pressure valve generated, need to absorb a large amount of heats due to dry ice sublimation, and heat enters in external environment with gas, it is possible to well withstand the test of big fire; The pouring type flame resistant glass arranged is being met after high temperature, the fire prevention glue-line of glass central, clear jelly shape can scleroma rapidly, forms an opaque fire-proof heat insulation board, while stoping propagation of flame, also stops high temperature fire face of supporting or opposing to be conducted; The composite fireproof glass arranged, when fire occurs, side towards the fire glass is fried very soon after meeting high temperature to be split, and its glue interlayer foaming and intumescing about ten times in succession of preventing fires form hard oyster white bubble shape Formica, effectively block flame, isolated high temperature and obnoxious flavour; The wired flame resistant glass arranged, the middle wire cloth arranged can improve the overall resistance to impact shock of flame resistant glass.
