The foamable synthetic resin raw material supplied between the
When a composite composite panel for building is manufactured by curing it to form a laminated member and then cutting it to a predetermined size, it does not require a special heating means to cure the foamable synthetic resin raw material, and the composite composite panel for building can be manufactured at low cost. The present invention relates to a continuous manufacturing method and an apparatus for carrying out the method.

[Conventional technology]

In recent years, a laminated member in which a gutter is formed in the center of a metal plate as an outer wall material or an inner wall material of a building, and a synthetic resin that is foamed and hardened is filled between the gutter and a back material that covers the gutter. Architectural composite panels consisting of are becoming widely used due to their beautiful appearance, excellent heat insulation, fire protection and durability and good workability.

As a method for continuously producing such a composite panel for construction, a strip-shaped metal plate is continuously formed into a forming roll group as disclosed in Japanese Patent Publication No. 59-17675 and Japanese Patent Publication No. 62-32012. Guided metal is formed into a predetermined shape having a gutter-shaped portion in the center in the width direction, and a molded metal plate of the backside material that is fed from the gutter-shaped recess of this formed metal plate or the backside material feeding device to cover the gutter portion of the formed metal plate The foaming synthetic resin raw material is discharged from the mixing and discharging machine to the surface facing the gutter-shaped recess, and it is located above and below the path for moving these in a laminated state, and the backside material is extruded by the foamed synthetic resin to form In this method, pressure was applied so as not to be extruded from the trough portion of the metal plate, and the foamable synthetic resin raw material was heated to foam and cure, and then cut into a predetermined size.

[Problems to be solved by the invention]

As described above, in the conventional method, a heating means is required to foam and cure the foamable synthetic resin raw material because the foamable synthetic resin raw material such as urethane foam surely polymerizes and completes the curing. Temperature for 70-10
Since it is as high as 0 ° C, foaming and curing of the foamable synthetic resin raw material is insufficient unless it is actively heated, and it is possible to manufacture stable quality composite composite panels with various advantages as described above. This is because it happened.

However, when heating is performed to foam and cure the expandable synthetic resin raw material in this way, the energy cost for heating and the equipment cost required for the heating device equipped with various auxiliary equipment are added to the product price of the product. In addition, it is difficult to constantly maintain the heating temperature at the optimum temperature for foaming and curing the expandable synthetic resin raw material, and it is difficult to inexpensively and easily manufacture a stable composite composite panel for construction. was there.

[Work]

In order to manufacture a building composite panel using the continuous manufacturing apparatus for a building composite panel according to the present invention having such a configuration, first, a strip-shaped metal plate A wound in a coil shape is set on the uncoiler of the sending section 1. After being continuously fed through a pinch roll, a concavo-convex pattern is formed on the metal plate A by the embossing device 4 via the looper 3, the shape of the embossed metal plate A is corrected by the leveler 5, and then the forming roll group is formed. 6 is formed into a predetermined shape having a gutter-shaped portion at the center in the width direction, and the formed metal plate A formed by the forming roll group 6 is heated to a temperature of 20 ° C. or higher by the preheating device 7. The preheating device 7 is provided with a temperature of the formed metal plate A 20 depending on the ambient temperature and the heat generated during processing by the embossing device 4.
It may not be used when the temperature is above ℃. Further, the strip-shaped backing material C is set in advance in the uncoiler of the backing material feeding device 8, and the backing material C is fed by the backing material feeding device so as to cover at least the gutter-shaped recess of the formed metal plate A. . At this time, in the first and third inventions, the backside material C may be sent out as it is by the backside material feeding device 8, but in the second and fourth inventions, the backside material C fed from the backside material feeding device 8 is heated. It is heated to a temperature of 50 to 80 ° C. by ′ and reaches the position where it covers the trough-like recess of the formed metal plate A due to the back material C that has been in stock absorbing moisture and weakening the stiffness. Before the above, the occurrence of phenomena such as side waves, cutting, and protrusion from the trough-shaped recess of the molded metal plate A is prevented, and the reaction rate of the low-temperature type expandable synthetic resin raw material B discharged from the mixing / discharging machine 9 is lowered. To prevent this. Thus, the back surface material C, which is also continuously fed from the back surface feeding device 8 to the continuously formed metal sheet A having a temperature of 20 ° C. or more, covers at least the trough-like recess of the metal sheet A. Before reaching the temperature, the low temperature type foamable synthetic resin raw material B (for example, low temperature type foamable urethane resin manufactured by MDI Kasei Co., Ltd.) having a foaming start temperature of 20 to 30 ° C. and a curing completion temperature of 30 to 70 ° C. The raw material, trade name RP-435SE3B) is mixed and discharged to the surface of the molded metal plate A facing the trough-shaped recess of the molded metal plate A or the back surface material C of the back surface material C fed from the back material feeding device 8. Then, between the trough-shaped recess of the molded metal plate A and the back surface material C, the molded metal of the upper and lower two sets of conveyors 10 installed in the area where the low temperature type expandable synthetic resin raw material B foams are provided. Opposing surfaces adjusted to the depth of the trough-like recess of the plate A In a trough-like recess the outer surface and the outer surface of the rear material C of the molded metal plate A is moved by holding to complete the foaming and curing of the low temperature expandable synthetic resin material B, followed by the conveyor 10
A composite panel for construction can be manufactured by cutting a laminated member composed of the molded metal plate A, the foamed and hardened low temperature type foamable synthetic resin raw material B and the backing material C with a cutting machine 11 to a predetermined size. At this time, as in the second and fourth inventions, the low-temperature foaming property in which the backing material C fed from the backing material feeding device 8 is heated to a temperature of 50 to 80 ° C. by the heating device 8 ′ and is discharged from the mixing and discharging device 9 Backing material feeding device 8 for synthetic resin raw material B
In the case of mixing and discharging the back surface material C of the back surface material C sent from the surface of the molded metal plate A facing the trough-like recess, the cream time of the low temperature type expandable synthetic resin raw material B is shortened and the unfoamed low temperature type By shortening the time during which the foamable synthetic resin raw material B is attached to the back surface material C, an uneven pattern is generated on the back surface material C at the position where the low temperature type foamable synthetic resin raw material B is discharged, and the commercial value is reduced. The occurrence of the phenomenon can be prevented, and the creaming time of the low temperature type expandable synthetic resin raw material B is shortened and the foaming efficiency is improved, so that the use amount of the low temperature type expandable synthetic resin raw material B can be reduced. .

When the metal plate A sent from one of the uncoiler and the pinch roll of the sending unit 1 is consumed and becomes the end in the process of manufacturing the composite panel for construction as described above, the metal plate A is clamped by the connecting device 2. While the metal plate A stored in the looper 3 is consumed by cutting with the cutting machine, the trailing end of the metal plate A is cut by a cutting machine and the other uncoiler and pinch roll of the feeding section 1 are cut. The front end of the new metal plate A is cut by a cutting machine so that the front end of the new metal plate A can be connected by butt welding, caulking, etc.
It is not necessary to stop the device by connecting the front end of the device with butt welding or caulking.

Further, when the preceding back surface material C fed from one of the uncoiler and the pinch roll of the back surface material feeding device 8 is consumed and becomes the end, the rear end of the preceding back material C and the front end of the back material C to be fed next are It is not necessary to stop the device by connecting the device with the connecting device.

Needless to say, the embossing device 4 is not necessary when the manufactured composite panel for building does not need to use the metal plate A on which the uneven pattern is formed.

〔The invention's effect〕

As described above in detail, the continuous manufacturing method and apparatus for a building composite panel according to the present invention has a high foaming start temperature of 30 to 50 ° C. and an effect completion temperature as the conventional foamable synthetic resin raw material as the expandable synthetic resin raw material. Also, unlike the high temperature of 70 to 100 ° C, the foaming start temperature can be increased by effectively reducing the amount of freon to be added, the amount of added water, or the amount of catalyst.
A low-temperature foamable synthetic resin weight loss with a curing completion temperature of 30-70 ° C at 20-30 ° C is used, and a reaction occurs immediately at a low foaming start temperature of 20-30 ° C of such a low-temperature foamable synthetic resin raw material. Of the formed metal plate when the low temperature type expandable synthetic resin raw material is located between the gutter-shaped recess of the formed metal plate and the backside material having a gutter-shaped part in the widthwise center so that foaming starts. A temperature of 20 ° C or higher, and the upper and lower sides of which the gap is adjusted to the depth of the trough-shaped recess of the molded metal plate so as not to release the heat of polymerization generated in the polymerization process of the low-temperature type expandable synthetic resin raw material 2
It is indispensable in the conventional manufacturing method of composite panels for buildings by organically combining the means of raising the curing completion temperature of 30 to 70 ° C of low temperature type expandable synthetic resin raw materials using a pair of heat insulating conveyors. It was a groundbreaking invention that succeeded in removing the cure oven, and as a result of succeeding in removing the cure oven in this way, heating in the cure oven was superior to the conventional method and apparatus for manufacturing composite composite panels equipped with the cure oven. It does not require the petroleum-based fuel or electricity needed for.

Not only does it have many economic advantages, but it is easy to operate because there is no need for troublesome temperature control in the cure oven due to the difference in the temperature of the metal plate during the winter and summer. In addition to the above advantages, when the backing material sent from the backing material feeding device is heated to a temperature of 50 to 80 ° C. by the heating device as in the second and fourth inventions, Before reaching the position to cover the trough-shaped recess of the formed metal plate due to the backing material in stock, which absorbs moisture and becomes weak, the side-wave, cut, and trough-shaped recess of the formed metal plate It is possible to prevent the occurrence of phenomena such as squeezing out of the resin, and to prevent the reaction temperature of the low temperature type expandable synthetic resin raw material discharged from the mixing and discharging machine from decreasing, and at the same time, the low temperature type discharged from the mixing and discharging machine. Effervescent synthetic When the resin material is mixed and discharged on the surface of the backing material sent from the backing material feeding device, facing the trough-shaped recess of the molded metal plate, the cream time of the low-temperature foamable synthetic resin material is shortened and unfoamed. Of the phenomenon in which the low-temperature foamable synthetic resin raw material adheres to the backside material reduces the product value due to the unevenness of the backside material at the position where the low-temperature foamable synthetic resin raw material is discharged. In addition to being able to prevent the occurrence, the cream time of the low temperature type expandable synthetic resin raw material is shortened and the foaming efficiency is improved, so that the amount of the low temperature type expandable synthetic resin raw material used can be reduced. Its industrial value is very large
