Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite plate having excellent design and functionality,

The present invention relates to a composite plate and a method of manufacturing the same, and more particularly, to a composite plate excellent in design and function by applying various materials to the edge of a plate, and a manufacturing method thereof.

There are various kinds of plate materials for interior materials, exterior materials, furniture materials, and interior materials widely used in the past. Typical examples are membrane method plate, edge banding method plate material, mold injection method and mold foaming method plate material and high pressure pressing method plate material .

First, the membrane method is a plate made by coating the surface of a sheet by pressing a thin film and a shape paper such as a PVC film, a paper coated shape paper together with hot air. Membrane method is a method used for the lowest cost product by applying a large amount of adhesive to the synthetic wood such as MDF by applying a large amount of adhesive on the thin shape of 0.1 ~ 0.6mm thickness. The drawbacks are the hazard of spray adhesives and the low durability of the surface of the plate.

Edge Bending Method The edge band is made of a material such as ABS, acrylic, PE, PP, PVC, etc. The edge band is a plate made by attaching an edge band wrapped in a roll shape to the edge of the plate with the surface material. It is attached with adhesive. The edge bending method exposes a joint of the edge by a manufacturing method widely used in middle and low-priced products, easily adheres to the edge of the edge and the plate material, and peeling occurs during use.

Mold Injection and Mold Foaming Method The plate material is produced by attaching the mold of the product to the injection machine and liquefying the thermoplastic resin in the chip state such as PE, PP, ABS by high heat and injecting it instantaneously into the mold to form the edge of the sheet material. As a plate material manufactured by a method of foaming a urethane foam on the edge of a plate mounted on a mold using a foaming device to form a rim of a plate material, a mold injection and a mold foaming method produce a product using a die, And it is difficult to manufacture due to the mold preparation. In particular, in the case of the injection molding method, it is impossible to produce a large-sized plate.

The high-pressure press method plate is a high pressure pressurized plate material such as unsaturated polyester type BMC (Bulk Molding Compound) artificial marble plate material, PMMA (Poly Methyl Methacrylate) acrylic artificial marble plate material, phenol type bakelight plate material, Which is too heavy and hard to be processed, and there is a limitation in expressing the color of the border.

3 and 4 are views for explaining a method of manufacturing a composite plate according to the present invention.

4 and FIG. 4, the composite plate shown in FIG. 4 may be a rectangular plate-like plate, a circular plate-like plate, or a partly circular plate- And may be formed in a plate shape having a curved shape.

a) The intermediate core member 100 is prepared.

For example, the middle core member 100 may be formed in a rectangular plate shape. Since the middle core member 100 is not a portion exposed to the outside of the composite plate member, the middle core member 100 may have a partially- As shown in FIG. That is, the intermediate core member 100 may be formed in various forms since it is required to support the frame member 130 at a predetermined position.

5 is a view illustrating various forms of the frame member.

5, the frame member 130 may have a rectangular cross-sectional shape (a) and a substantially rectangular cross-sectional shape, but may have a curved shape (b), a trapezoidal shape (c) d), a two-stage structural shape (e), and a shape (f) in which a portion is removed from a rectangular shape.

The square shape (a) may be a most commonly used shape of a slab, which is the most general shape, and the thickness may become smaller toward the end as shown in the figure.

The curved surface (b) is formed in a substantially rectangular shape, but its thickness may be smaller toward the end and the end may be curved.

The trapezoid shape (c) is a rectangular shape that is obliquely left / right-angled at an angle of 0.1 degrees or more, for example, 0.1 to 26.5 degrees with respect to a plane perpendicular to the coupling surface of the frame member 130 with the intermediate core member 100 Which can be beveled on at least one surface and beveled at an asymmetrical angle according to the demand of the customer.

The shape (f) in which a part is removed from the rectangular shape can be a shape in which the shape of the cross section has a rectangular shape and the shape of the triangular shape is selectively removed from the cross section.

When the frame member 130 is formed of a porous material having absorbency (for example, color MDF, wood, carbonized wood, plywood, bamboo, engineering wood, felt fiber or the like), the finishing material 140 is filled The edge member 130 may be made of a nonporous material having no absorbing ability (for example, artificial marble, marble, or marble) although the finishing material 140 such as resin is absorbed to bond the surface materials 110 and 120 and the edge member 130 to each other. , Bakelite, phenol plate material, acrylic panel, etc.), the surface is smooth and the finishing material 140 is not absorbed, so that the bonding force between the surface materials 110 and 120 and the frame member 130 is deteriorated. Therefore, in this case, the frame member 130 can strengthen the bonding force with the surface materials 110 and 120 through the finishing material 140 by sanding the surface, forming a scratch, or applying a primer.

6 is a view for explaining a method of joining the frame member and the intermediate core member.

Referring to FIG. 6, the frame member 130 may be coupled to the intermediate core member 100 through an adhesive 151.
