PATENT OFFICE.

200 parts of freshly annealed zinc oxide become intimately mixed with 100 parts of hollanged asbestos and with carbonated water kneaded into a thick dough. This dough is rolled onto an iron wire net pressed in until it connects with it completely and forms a body, which gains the appearance of a cardboard lid. After the plate created in this way some Minutes after it has dried, it is impregnated with a concentrated zinc chloride solution and rolled again. The plate can be produced in any thickness, length and width.

Want . if you give the plate more consistency or a color, you can do it before Dry with colored sand, pebble powder, any earth color or refractory filler sprinkle it or mix it with the mass and "roll it in".

After the plate has dried, it is coated again with concentrated zinc chloride and dried again.

■ After this drying, the plate läfst 24 to 48 hours in the water bath aussüfsen, to rid them of excess acid. The plate can then be polished without the use of lubricants and given the necessary flexibility by rolling again.

The plates take up water only to a small extent, but without releasing it respectively to let through; for such panels, however, which are exposed to constant weather conditions the increased watertightness can be achieved partly by watertight paints, partly by the following Procedure can be achieved.

The plates are soaked in a water-glass solution, which causes them to Greedily suck up liquids. After the water glass has dried, the plate is soaked in skimmed milk, creating a casein-waterglass connection, which gives the panels special watertightness and is suitable for the easily flammable To replace fatty paints.

Iron or manganese chlorine can also be used as a substitute for zinc chloride.

The incombustible zinc oxide, mixed with the known also incombustible asbestos, has the property of becoming a hard mass by means of zinc chloride impregnation connect to. This mass is insoluble in water and becomes even more resistant and hardness in the same. The iron wire net is against the influences from destruction the fire and the water sufficiently protected and causes the asbestos fibers fixed connection of the plate.

The method described therefore creates an absolutely incombustible, watertight, Specifically lighter / less voluminous, poorly heat conducting, more flexible and more resistant Body shown, which the inventor calls "Superator fire protection panel".

The Superator fire protection panels can be used for the following purposes: For Achieving fire safety in theaters, public institutions, in industrial operations

and trade, for ships, railways etc., partly by lining wooden parts and other easily combustible bodies the Superator fire protection panels, partly through their independent use, e.g. B. to Theater decorations, curtains, ceilings, wallpaper, fabrication aids, etc., also for roofing, as fire protection blankets during the fire, as insulation to protect against Heat radiation and for other technical purposes. .

Claims (1)

Patent claim: The method described for the manufacture of fireproof and waterproof panels by Use of an iron wire net in combination with a zinc oxide-asbestos mixture, the latter rolled onto the wire mesh and the body produced in this way by means of a zinc chloride impregnation is converted into a uniform, solid plate, as well as the application of such Plates for the specified purposes.
