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, a wooden fire door, including the door plant main part, the door plant main part is including setting up at outmost wooden door pocket 1 and range upon range of first insulating layer 2 that sets up in wooden door pocket 1, fire-resistant mineral substance packing layer 3 and second insulating layer 5, first insulating layer 2 and second insulating layer 5 are cement, fire prevention glass 4 is still pasted respectively to wooden door pocket 1's both sides, when the conflagration takes place, set up and to play fire-retardant effect of fire prevention in fire door outlying wooden door pocket 1 and fire prevention glass 4, set up in the first insulating layer 2 of wooden door pocket 1 inlayer, fire-resistant mineral substance packing layer 3 and second insulating layer 5 can prevent effectively that high temperature from conducting to the back of the body fire face from the one side that is 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.

The fireproof glass is high-strength single-layer cesium-potassium fireproof glass, is a first fireproof barrier, is relatively thin, and improves the attractiveness and fireproof effect of the whole wooden fireproof door. The fireproof glass 4 is installed on the wooden door pocket 1 through a screw 10.

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 the export branch pipe 9 of putting out a fire on wooden door pocket 1's surface, the export surface sealing of branch pipe 9 of putting out a fire is provided with second polyethylene wax, when the conflagration takes place, because polyethylene wax's melting point is 90-120 ℃ (along with molecular weight change), so the back is melted by the heating again, carbonic acid flows into in the gap of fire-resistant mineral substance packing layer 3 and on wooden door pocket 1's surface respectively through outlet pipe 7 and branch pipe 9 of putting out a fire from 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 wooden door pocket 1 is uniformly coated with the ammonium polyphosphate flame-retardant layer, and the ammonium polyphosphate flame retardant has high thermal stability and good dispersibility, so that after the fireproof glass is damaged, the 0.4 mm ammonium polyphosphate flame-retardant layer arranged on the surface of the wooden door pocket 1 can be rapidly expanded to form a foam layer of 10-25 mm after encountering fire, thereby protecting the wooden door pocket 1 and further improving the fire resistance, and playing a backup role.

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.
