CONSTITUTION: A sticker 2 of a predetermined width is formed on one side surface of a metal thin plate 1, sticky mortar 3 is laminated, fiber 4 with binder is laminated thereon, FRP waste comminuted particles 5 are filled, further the fiber 4 with the binder is laminated or the mixture of them are filled, and backed with a plate material 6 to meet the rising height of the sticker 2 to form a composite panel.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite panel such as a building material that effectively uses FRP waste.

[0002]

FRP, that is, glass fiber reinforced resin, is
Nowadays it is used in a wide variety of fields such as building materials, furniture, vehicles, etc. Therefore, the amount of scraps is enormous every year. At present, most of this FRP waste is crushed and divided into various granular shapes and discarded.

[0003]

Such crushed particles of FRP waste have a very irregular shape and are composed of a thermosetting resin (polyester) which can no longer be melted and molded, and is burned. If this is done, the furnace will be damaged and a large amount of glass will remain unburned, so at present, there is no choice but to dispose of this and there are serious problems such as waste pollution.

On the other hand, a large amount of resources are consumed in building materials and the like, and the necessity of resource saving has been pointed out in various fields today. An object of the present invention is to solve such a problem.

[0005]

As shown in FIG. 1, an extremely thin metal thin plate (1) having a thickness of 0.1 to 0.3 mm is provided on one side with a predetermined width (generally, about 10 cm, which corresponds to the thickness of a panel). 2) is formed, and an adhesive mortar (3) is layered on one surface of the metal thin plate, and a fiber material with a binder (4) is layered on the layer of the first-adhered mortar (3). FRP waste crushed granules (5) are filled, and a fiber material (4) with a binder is layered on it and lined with a plate material (6) such as plywood according to the rising height of the pier (2). This is a composite panel suitable for walls, roofs, floors, etc. of houses (temporary houses).

At this time, instead of layering as described above, a mixture of the fibrous material with a binder (4) and crushed FRP waste particles (5) is placed on the adhesive mortar (3) of the pier (2). It may be filled with only the rising height and lined with the plate material (6).

As the material of the thin metal plate (1), iron or the like is preferable to aluminum in view of adhesiveness, so-called steel paper, or a decorative sheet metal on which painting or wood grain printing is applied corresponds.

The adhesive mortar (3) refers to a mixture of an epoxy resin and other adhesives in order to improve the adhesiveness of ordinary mortar, and its layer thickness is about 1 cm.

The fibrous material with a binder (4) is a material in which the fibrous material is coated and hardened with a binder having an adhesive property such as a resin, and like FRP, the binder is polyester or fibrous material. A typical example is glass fiber.

The FRP waste crushed particles (5) have various shapes, and some of them have a complicated streak shape, but in the present invention, these are collectively referred to as such.

The description such as "above" in the present invention does not mean the upper and lower positional relationship on the ground of the finished product, and the steps do not matter, only from the order of description.

[0012]

[Function] A thin metal plate in the composite panel of the present invention (1)
Are normally located where they are exposed to the outer surface during use. Therefore, the metal exhibits properties such as hardness, durability, and incombustibility, but since it is extremely thin in order to have lighter weight, economical efficiency, designability, etc., it easily bends as it is. It dents or dents, causing damage. However, in the present invention, since the adhesive mortar (3) is applied in a layered manner to them, they are integrated to form a surface layer portion having a solid metal surface.

The binder-attached fiber material (4) prevents the FRP waste crushed particles (5) from moving and stably stores and holds the FRP waste particles in the panel, and at the same time, secures an appropriate void. It is useful for weight reduction of panels and improvement of heat insulation.

In this way, the FR was in trouble in the disposal process.
The crushed particles of P waste can be used as a panel with high utility value in building materials and the like.

[0015]

Example: length 2,400 mm, width 600 mm, thickness 0.
2mm stainless steel or wood grain printed iron plate with 90mm width, 2,400mm length, and 20mm thickness wooden splints are glued or nailed to both lateral edges and the center to form an upright resin epoxy mortar. About 10
mm thick, and the glass fiber for FRP with polyester resin adhered to the surface is adhered in a layer form of about 10 mm,
On top of that, crushed FRP waste particles are filled to a thickness of about 60 mm, and the glass fiber with polyester resin is further added to about 10 m.
It is attached about m thick, and it is 2,400 vertically on the rising head of the pier.
mm, width 600 mm, thickness 40 mm Plywood is glued or nailed to make a wall panel for a simple house.

[0016]

As described above, according to the present invention, the FRP waste which has conventionally been troubled with its disposal and must be disposed of,
It can be effectively used as a lightweight and highly insulating building material, and has the effect of greatly preventing waste pollution and conserving resources.
