DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, in the present invention, an environmentally friendly non-combustible plate 1 is made of a foamed plastic plate impregnated with an emulsion of cement clay, charcoal powder or the like, and cured to form a plate having a large number of air bubbles 3. A layer 2 is formed, and a charcoal layer 4, 5 such as a plastic film is preferably provided on the front and back surfaces of the plate material layer 2, respectively.

In this case, when it is necessary to increase the thickness of the plate material layer 2, another plate material layer 6 can be laminated as shown in FIG.

Further, referring to FIG. 3, an environmentally friendly manufacturing method of a noncombustible material plate according to an embodiment of the present invention will be described in detail. In this embodiment, first, a plate material layer 2 having a desired size (if necessary, a plate material layer is also placed in a forced rotating tank 14 filled with an emulsion 12 such as cement and a rotor 13 through a first conveyor 11). Foamed plastic plate 15)
Input. In the forced rotation tank 14, the cement emulsion 12 is forcibly flowed by the rotor 13 which periodically rotates in the reverse direction, and the cement emulsion is sufficient without degassing the foamed plastic plate 15 by this flow action. And the cement emulsion 12 is impregnated substantially uniformly over the entire surface. The foamed plastic plate material 15 </ b> A impregnated with the cement emulsion 12 is conveyed to the de-emulsion unit 17 via the second conveyor 16.

In the de-emulsion section 17, the cement emulsion 12
Is transported by a third group of conveyors 18 and passes between a group of extraction rollers 19 and a perforated plate 20 to apply a relatively low pressure to the foamed plastic plate 15A. As a result, a part of the cement emulsion is squeezed from the foamed plastic plate material 15A impregnated with the cement emulsion 12, and then conveyed toward the working chamber 21. In FIG. 3, for example, a perforated plate 20 is provided on the upper surface of the emulsion receiver, and the cement emulsion 12 is disposed between the perforated plate 20 and the squeezing rollers 19 arranged at a predetermined distance from the perforated plate 20.
It is also preferable to make it pass through the foamed plastic plate material 15A impregnated with.

In the working chamber 21, a part of the cement emulsion is covered with a preferably plastic film 23 as a charcoal layer 4, 5 on the foamed plastic plate material 15B, and then on a fourth conveyor 22. The attached foamed plastic plate 15B is turned upside down by covering the cured corrugated plate 24 so as to prevent uneven distribution of the impregnated cement emulsion.

Further, before the cement emulsion impregnated with the foamed plastic plate material 15C which has been turned upside down is hardened (in a semi-cured state), it is placed on the corrugated conveyor 25, and as apparent from FIG. 15C is conveyed while curving the whole without concentrating stress on a part.
Next, a curing process is performed to cure the film.
You may heat at -100 degreeC. At this time, the heating may be performed over the entire 21 or may be performed only when the heater 21 is positioned on the conveyor 26 at the re-entry stage.

In this case, it is possible to mix the clay emulsion and the charcoal powder in a desired ratio in addition to the cement emulsion. In the curing step at this time, steam may be used.

The resulting foamed plastic plate 15D functions as an environmentally friendly noncombustible material plate. In this environmentally friendly noncombustible material plate, a strong activated type can be obtained together with the charcoal layer. As shown in FIG. 4, which is somewhat exaggerated, the plastic layer 15b surrounding the cell portion 15a of the foamed plastic plate is connected to form the cement layer 1
5c can also obtain uniformity

[0014]

According to the environmentally friendly manufacturing method of the noncombustible material plate of the present invention constructed as described above, a cement layer and a charcoal layer having a large number of air-permeable bubbles are effectively formed, and the weight is reduced. In addition, sufficient fire resistance, hygroscopicity, and soundproofing can be obtained, and in addition to this, a remarkable effect can be achieved, such as being able to provide environmental measures together with the activator of charcoal. In addition, ceramic heat-insulating tiles can be used as outer walls of spacecraft as an advanced measure of heat resistance.
