And a fire-retardant fireproof additive is filled in the gap of the fire-retardant mineral filler layer, and is one or a combination of more of chlorinated paraffin, tributyl phosphate and aluminum borate.
The door plant main part is internal to be installed the water storage chamber still in the upper end, the water storage chamber is provided with downwardly extending and deepens outlet pipe in the fire-resistant mineral substance packing layer, the surface of outlet pipe is provided with a plurality of apopore, the sealed surface of apopore is provided with first low molecular weight polyethylene, the water storage intracavity is filled and is had carbonic acid.
The outlet pipe still is provided with the export and is in the branch pipe of putting out a fire on the surface of steel door pocket, the export surface seal of branch pipe of putting out a fire is provided with second polyethylene wax.
And the outer surface of the steel door pocket is uniformly coated with an ammonium polyphosphate flame-retardant layer.
The utility model has the advantages that: the utility model discloses a prevent fire door, including the door plant main part, the door plant main part is including setting up at outermost steel door pocket and range upon range of first insulating layer, fire-resistant mineral substance packing layer and the second insulating layer of setting in the steel door pocket, first insulating layer and second insulating layer are cement, when the conflagration takes place, set up and to play the fire-retardant effect of preventing fires in preventing fire door outlying steel door pocket, set up in the first insulating layer of steel door pocket inlayer, fire-resistant mineral substance packing layer and second insulating layer can effectively prevent that high temperature from conducting to the face of a fire from the one side that is close to the intensity of a fire.
Drawings
Fig. 1 is a schematic cross-sectional structural view of a first embodiment of the present invention;
FIG. 2 is a schematic sectional top view of the structure of a second embodiment of the present invention;
fig. 3 is a schematic front sectional view of a second embodiment of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples, wherein it is noted that, in the description of the invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular manner, and therefore should not be construed as limiting the present invention. The terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1 to 3, the fireproof door comprises a door panel main body, wherein the door panel main body comprises a steel door pocket 1 arranged on the outermost layer, and a first heat insulation layer 2, a fireproof mineral filler layer 3 and a second heat insulation layer 5 which are stacked in the steel door pocket 1, and the first heat insulation layer 2 and the second heat insulation layer 5 are both made of cement. When the conflagration takes place, set up in preventing that fire door outlying steel door pocket 1 can play the fire-retardant effect of fire prevention, set up in first insulating layer, fire-resistant mineral substance packing layer and the second insulating layer of 1 inlayer of steel door pocket and can effectively prevent that high temperature from conducting to the face of a back of the body of a fire from being close to the intensity of a fire.
In this embodiment, the refractory mineral filler layer 3 is one or more combinations of alumina powder, calcium carbonate particles and perlite particles.
In this embodiment, in order to obtain better fireproof effect, there are two embodiments:
one embodiment is that the fire-retardant additive is filled in the gap of the fire-retardant mineral filler layer 3, the fire-retardant additive is one or a combination of more of chlorinated paraffin, tributyl phosphate and aluminum borate, and the chlorinated paraffin, the tributyl phosphate and the aluminum borate all have certain fire-retardant effect, so that the fire-retardant capability of the fire-retardant mineral filler layer is enhanced.
In another embodiment, a water storage cavity 6 is further mounted at the upper end in the door panel main body, the water storage cavity 6 is provided with a water outlet pipe 7 which extends downwards and extends into the refractory mineral filler layer 3, the surface of the water outlet pipe 7 is provided with a plurality of water outlet holes 8, the surface of each water outlet hole 8 is hermetically provided with first polyethylene wax, and the water storage cavity 6 is filled with carbonic acid; outlet pipe 7 still is provided with export branch pipe 9 of putting out a fire on the surface of steel door pocket 1, the export surface sealing of branch pipe 9 of putting out a fire is provided with second polyethylene wax, when the conflagration breaing out, because polyethylene wax's melting point is 90-120 ℃ (along with molecular weight change), so the back of melting by the heating again, carbonic acid flows into in the gap of fire-resistant mineral substance packing layer 3 and on the surface of steel door pocket 1 respectively through outlet pipe 7 and branch pipe 9 of putting out a fire in water storage chamber 6, because high temperature, carbonic acid decomposes into carbon dioxide and water, can play good fire extinguishing and cooling effect.
The outer surface of the steel door pocket 1 is uniformly coated with an ammonium polyphosphate flame-retardant layer, and as the ammonium polyphosphate flame retardant has high thermal stability and good dispersibility, the 0.4 mm ammonium polyphosphate flame-retardant layer arranged on the surface of the steel door pocket 1 can quickly expand after being mixed with fire to generally form a 10-25 mm foam layer, so that the steel door pocket 1 is protected and the fire resistance is improved.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
