Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lightweight and three-dimensional artificial marble panel suitable for interior partition panels, architectural panels such as living room doors, and furniture panels such as closet doors and kitchen doors.

[0002]

[Prior art]

 Traditionally, man-made marble boards have been widely used for the tops of tables, system kitchens, and various counters. However, since these artificial marble plates are relatively thick and heavy, they are inconvenient to handle when used for applications such as interior panels and doors, and special hinges with load-bearing capacity that are more commercially available than those commercially available. There was a problem such as the need for.

Further, in order to impart a three-dimensional pattern to these panels for the purpose of improving the design, an attempt has been made to apply unevenness using a cutting machine such as a router or to heat-bend. However, the three-dimensional pattern in this case was within the range of the thickness of the artificial marble plate, and the standing feeling was poor. Moreover, when cutting from a flat plate, the amount of cutting increases, which causes problems such as increased cost and increased working time. When bending is used, the bent part is large and lacks sharpness. Only the ones with poor design were obtained.

In addition, since it is necessary to perform post-processing such as inlaying and coloring when attempting to make the panel multi-colored, it is not practical.

[Problems to be solved by the device]

 An object of the present invention is to provide an artificial marble panel which is suitable for use as an interior panel, a door, and the like, and which is lightweight and has an excellent design property such as a three-dimensional effect.

[0006]

[Means for Solving the Problems]

 According to the present invention, there is provided an artificial marble panel, characterized in that a plurality of thin artificial marble plates are combined and laminated on a substrate so as to provide uneven portions and / or hollow portions. The artificial marble panel is provided in which a low specific gravity material is embedded and filled in the hollow portion, and further, an artificial marble plate having a different color tone is used in combination. The artificial marble panel is provided.

That is, if thin artificial marble plates are laminated and used, cavities and irregularities can be easily formed by the laminating method, and artificial marble plates having different color tones can be used for multicoloring. They found it easy and reached the present invention.

Hereinafter, the present invention will be described with reference to the drawings. In the present invention, an acrylic artificial marble plate, an unsaturated polyester resin-based artificial marble plate or the like which is usually commercially available as a thin artificial marble plate 3 can be used without particular limitation, but the thickness thereof is about 1.0 to 4.0 mm. , And preferably in the range of 2.0 to 3.0 mm. As the substrate 2, plywood, MDF, wood boards such as particle boards, wood-based flash panels, steel panels and the like can be used without particular limitation.

The artificial marble panel 1 of the present invention is manufactured by laminating a plurality of thin artificial marble plates 3 on the above-mentioned substrate 2, and at that time, the uneven portion 5 and / or the hollow portion 6 are provided. It is necessary to combine and laminate so as to open. For example, instead of laminating the thin artificial marble plates 3 so as to completely overlap each other, the concavo-convex portion 5 is formed by partially providing a portion where the upper artificial marble plate 3a is missing, or the upper artificial marble plate 3a. The artificial marble plate 3b below the portion covered with 3a may be omitted and laminated so that the hollow portion 6 can be formed. The number of stacked layers is appropriately selected as needed.

When the artificial marble plates 3 are bonded to each other as an adhesive used for lamination, for example, an acrylic resin adhesive is used. When the artificial marble plates 3 and the substrate 2 are bonded, For example, rubber adhesives and the like can be mentioned, but the invention is not limited thereto.

Further, if different color tones are used as the artificial marble plate 2, the multicolored artificial marble panel 1 can be easily manufactured.

In addition, in the hollow portion 6 of the artificial marble panel 1 described above, various foams such as styrofoam, foam beads, a foaming resin typified by a two-component reactive urethane resin, and a low specific gravity material 4 such as a paper honeycomb are provided. By embedding and filling, it is particularly preferable because it is possible to prevent deterioration of mechanical strength, impart soundproofing properties, and heat insulating properties while maintaining the property of being lightweight and easy to handle due to the provision of the hollow portion 6.

In order to prevent warpage due to the difference in linear expansion coefficient between the artificial marble plate 3 and the substrate 2, a vinyl chloride plate, an acrylic resin plate or the like having a linear expansion coefficient similar to that of the artificial marble plate 3 is used as the substrate 2. It is also possible to attach the backing plate 7 to the back surface. At this time, it is preferable that the thickness of the backing plate 7 is about the same as that of the artificial marble plate 3.

【Example】

 Example 1 Two artificial marble plates having a thickness of 3.0 mm and different tones (Okura Kogyo, trade name: Eldor) are used as substrates (plywood having a thickness of 12 mm and a length and width of 450 × 750 mm) as shown in FIG. It was laminated on top and a 3.0 mm thick vinyl chloride plate was attached as a backing material to the back surface of the substrate to obtain an artificial marble panel of the present invention. I actually used this as a door for a system kitchen, but no warping was seen. Various properties are shown in Table 1.

Example 2 An artificial marble panel of the present invention as shown in FIG. 2 was obtained in the same manner as in Example 1 except that the hollow polystyrene was embedded. I actually used this as a door for a system kitchen, but no warping was seen. Various properties are shown in Table 1.

Comparative Example A commercially available artificial marble plate having a thickness of 6 mm is cut with a router to form an uneven portion, which is then adhered to a substrate (plywood having a thickness of 12 mm and 450 × 750 mm). As a backing material, a 3.0 mm thick vinyl chloride plate was adhered to obtain an artificial marble panel as shown in FIG. Various properties are shown in Table 1.

【effect】

 The present invention makes it possible to easily provide a lightweight and artificial marble panel having a multicolored three-dimensional pattern. Therefore, it has become possible to use artificial marble panels for interior panels, doors, etc. that were difficult to use in the past. Further, since the scrap material of the artificial marble plate can be effectively used, the artificial marble panel can be produced at a low cost.
