Conventional heat insulating boards of this type employ a manufacturing method in which a refractory material is uniformly dispersed throughout the foamed structure of the core insulating material, a sheet-like material is layered on top of this, and then formed and cured in a curing oven, etc. was. However, when this type of manufacturing method has a thermal insulation value of 1, there are disadvantages in that the following points are lacking. That is, (1) It is difficult to uniformly mix and discharge the foamed synthetic resin raw material and the refractory material, and the foamed structure becomes rough. ■
Since the foam structure is damaged, the foaming ratio and mechanical strength decrease. ■■ and ■ increase the amount of foamed synthetic resin used, leading to an increase in cost. ■The foamed synthetic resin leaks from the edge of the sheet during foam molding, staining the back of the insulation board and the mold material. In other words, when forming a flat sheet into a foam, the foaming pressure of the foam is used to mold the sheet into a shape, so even a slight deviation will cause the above-mentioned results. ■Especially in the case of a cross-sectional shape that has a bulge protruding from the recess of the metal hoop material, the side edges of the female part are molded and released at the same time.
There are many cases where the desired cross-sectional shape is not achieved. This is because the synthetic resin raw material in the process of foaming comes into direct contact with the mold material. That is, this is because a gap occurs between the current temperature of the mold material being heated and the temperature of the raw material that is being foamed.

In order to eliminate such drawbacks, the present invention locally laminates foamed synthetic resin containing fire-resistant aggregate only at the female joint, which is the weakest point in the fireproof structure, and foamed synthetic resin is applied to other parts. In addition to dispensing and laminating single resin, the formed sheet-like material is laminated and coated on the foamed synthetic resin, and the metal thin plate and the sheet-like material are fixed by the self-adhesive properties of the foamed synthetic resin, thereby achieving the desired fire resistance at low cost. The present invention proposes a method for manufacturing a heat insulating board that exhibits high foaming ratio, exhibits high foaming ratio, and does not cause dirt on the back surface of the heat insulating board or decrease in mechanical strength.

FIGS. 1(al) and (b) are a side view and a plan view schematically showing the apparatus used in the above manufacturing method, in which 1 is a band-shaped metal hoop material (hereinafter simply referred to as hoop material) which is continuously connected to the uncoiler 2. It is fed to the molding machine 3, and the molding machine 3
Then fold it into the shape shown in FIG. 2(a). That is, FIG. 2(,) shows the bent portions 4 of the male connection structure and the female connection structure by bending the left and right ends of the hoop material in the longitudinal direction, respectively.
5 is provided, and a recessed portion 6 is formed between the bent portions 4 and 5. The hoop material 1 formed in this manner is heated by a preheater 7 for approximately 40 to 90 CK. Specific examples of the preheater include those that use electricity, far infrared rays, gas, high frequency, etc. as a heat source. Reference numeral 8 is a mixer for discharging a mixture of fire-resistant aggregate 9 and foamed synthetic resin 10 onto the back surface 5a of the bent portion 5 of the hoop material 1 as shown in FIG. 2(b). Note that it is preferable that the discharge range S is not the entire back surface of the back surface 5a, but an area that is about 2 to 511 degrees inward from the tip. This facilitates the work of pasting the sheet-like material described later, and prevents a part of the foamed synthetic resin raw material 10 from going around to the surface 5c via the tip 5b of the bent portion 5, thereby suppressing its fluidity. This is useful for preventing leakage of the raw material 10. Specific examples of the fire-resistant aggregate 9 include pearlite grains, vermiculite, shirasu balloons, alumina bulbs, glass balloons, etc., and the size thereof is approximately 1 to 10 g/φ. Furthermore, the foamed synthetic resin raw material 10 is made of polyisocyanurate foam raw material, polyurethane resin (soft, hard, semi-hard), phenol resin, polyimide resin, etc., and is mainly used as a binder for the aggregate 9, a heat insulating layer, etc. It's something that works. Reference numeral 11 denotes a foamed synthetic resin raw material supply device, which is composed of, for example, a nozzle, and is used to supply the foamed synthetic resin raw material 12 into the recess 6 as shown in FIG. 2 (CJ).

The mold 13 rotates in the direction of the arrow, gradually dissolves at the exit, and forms again at the entrance. 16
The upper and lower mold conveyors 1, which are both mold members in the curing oven,
4.15 and is capable of heating to about 50 to 100 tZ', and is mainly useful for heating mold materials and curing foamed synthetic resin. Furthermore, although not shown, a dehumidifier can be added to the cure oven 16 and operated depending on the raw material. 17 is made by laminating one or more of kraft paper, asbestos paper, asphalt felt, and non-woven fabric, or by applying waterproof treatment to these sheet-like materials, or by applying metal foil (AI, Cu, Fe, etc.).
. This sheet-like material 17
As shown in FIG. 2(d) by the Autumn fabric forming machine 20, after being formed into a cord shape, a compound 21 consisting of a layer 10 is gradually formed on the back surface of the formed metal hoop material 1, The back surface of the resin 12 is covered as shown in the figure.
022 acts as a contact prevention material (IIm template) between the mold material and the foamed synthetic resin, and also has the function of preventing the foamed synthetic resin 1O112 from leaking out of a predetermined area. As a result, the insulation board has a foam 23 made only of foamed synthetic resin and a foam containing aggregate, the so-called fireproof layer 24. are integrally formed, and the metal hoop material 1 and the sheet-like material 17
When the foamed synthetic resin raw material is foamed, the self-adhesive properties of the foamed synthetic resin material allow it to be stuck together.

As mentioned above, according to the method for manufacturing a heat insulating board according to the present invention, a major feature is that a fire-resistant layer and a highly heat-insulating layer can be formed on the hoop material in the same line very easily and efficiently at low cost. There is. Also, form a goose-shaped mold with the formed hoop material 1 and sheet-like material 17, and insert the foamed synthetic resin inside it! Since it is made of foam, there is no leakage of resin to the outside. Furthermore, the joints, which are weak points in the fireproof structure of the heat insulating board, are reinforced by the fireproof layer. Furthermore, since the concave portion of the hoop material is filled with a single foamed synthetic resin, the foamed structure does not become rough, and the mechanical strength can be significantly improved.
