Conventionally, this type of building material panel has been made by using natural inorganic foam particles such as perlite and shirasu balloons with organic adhesives such as vinyl acetate emulsion, PVA, and rubber latex, or inorganic adhesives such as water glass and gypsum. A method has been known in which particles are bonded together and integrally formed into a panel.

Next, a method for manufacturing a panel for building materials according to the present invention will be explained using the drawings. Figure 1 is a schematic diagram showing the above manufacturing method, and 1 is a rotary kiln in which an alkali silicate such as sodium silicate and slaked lime, or (and) a saturated solution of alkaline alum such as potash alum or silicone resin are mixed. The solution was used as a foaming agent, and an appropriate amount of silicate powder such as pearlite powder, white carbon, or silica flour was mixed into this, and the mixture was kneaded until it became uniform.The resulting product was granulated into an appropriate shape and dried for several hours. The material is fired at 400 to 1000°C for 10 to 15 minutes using a burner 2 and foamed to form an artificial lightweight aggregate 3. The completely foamed artificial lightweight aggregate 3 is kneaded from an outlet 4. It is supplied to tank 8. On the other hand, after the thermoplastic resin pellets 5 are put into a hopper 6, they are fed into a kneading tank 8 in appropriate amounts by a screw conveyor 7. The thermoplastic resin pellets 5 may be made of, for example, vinyl chloride resin, polyethylene resin, vinylidene chloride resin, polystyrene resin,
These are pellets of thermoplastic resin such as ABS resin, or crushed waste from the production of these resins.
In the kneading tank 8, the artificial lightweight aggregate 3 and the thermoplastic resin pellets 5 are kneaded with a screw pin 9, and
Thermoplastic resin pellets 5 are formed by the residual heat of the artificial lightweight aggregate 3.
is melted and coated on the outer surface of the artificial lightweight aggregate 3. That is, the artificial lightweight aggregate 3 foamed and formed in the rotary kiln 1 is immediately fed into the kneading tank 8 in an appropriate amount from the outlet 4.
An appropriate amount of thermoplastic resin pellets 5 from the hopper 6 are sprinkled onto the mixture and kneaded by a screw pin 9. At this time, the artificial lightweight aggregate 3 has just been heated and has a residual heat of about 300 to 500°C, so the thermoplastic resin pellets 5 sprinkled on it are immediately melted and kneaded by the screw pins 9. As a result, a thin film is formed on the surface of the artificial lightweight aggregate 3 and coated. The artificial lightweight aggregate 3 thus coated is delivered onto the lower mold conveyor 11 from the outlet 10 at the bottom of the kneading tank 8 .
A hard sheet 13 such as a thin metal plate or a silica plate is placed on the lower mold conveyor 11 in advance, and the coating aggregate 3' is sent out on top of this.
is formed into a panel shape by the upper mold conveyor 12, and is closely attached to the top sheet 14 fed to the lower surface of the upper mold conveyor 11 at the same time to form a sandwich-like panel, which is gradually cooled and solidified. A building material panel A as shown in FIG. 2 is formed using thermoplastic resin 5' as a binder. In addition,
The top sheet 14 may be made of paper, cloth, plastic, etc., but may be omitted depending on the use and purpose of the building material panel.
