(57) [Summary] [Purpose] The present invention aims to provide an interior decorative panel using a leather material or the like as a skin layer. [Structure] In order, a skin layer 1 and a polyvinyl chloride foam layer 3
And a base layer 4, wherein the skin layer 1 is selected from leather or synthetic leather, the base layer 4 is selected from a hard board or a rigid polyvinyl chloride board, and a hot-melt adhesive layer is formed at the ends. 2 is interposed between the leather layer 1 and the polyvinyl chloride foam layer 3 and between the polyvinyl chloride foam layer 3 and the base layer 4 when the material of the base layer 4 is hard board, The interior decorative panel, wherein the layer 1 and the polyvinyl chloride foam layer 3 are welded to the base layer 4 by welding.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a decorative panel, and more particularly to a high-grade interior decorative panel whose surface is made of a leather or synthetic leather layer.

[0002]

[Prior art]

 Conventionally, a laminate is known in which polyvinyl chloride is used as the skin layer, polyvinyl chloride foam is used as the intermediate layer, and polyvinyl chloride is used as the support layer, and the ends are welded by welding.

[0003]

[Problems to be solved by the device]

 Along with the recent diversification of upholstery materials for buildings and the trend toward high-grade materials, there is a demand for laminated upholstery materials that use high-grade materials such as leather and synthetic leather for the surface layer. However, there was no standard indoor decorative panel using leather on the surface. If leather or synthetic leather is used as the skin layer, polyvinyl chloride foam is used as the intermediate layer, and hardboard is used as the support layer, leather or synthetic leather and polyvinyl chloride foam layer, and polyvinyl chloride are used. Since the foam layer and the hard board are not welded, it was not possible to weld them by the conventional welding process.

The present invention is intended to provide an interior decorative panel using a leather material or the like as a skin layer.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the interior decorative panel of the present invention is an interior decorative panel comprising a skin layer 1, a polyvinyl chloride foam layer 3 and a base layer 4 in that order, and the skin layer 1 is made of leather or synthetic material. It is selected from leather, the base layer 4 is selected from a hard board or a rigid polyvinyl chloride board, and at the end, the hot melt adhesive layer 2 is provided between the leather layer 1 and the polyvinyl chloride foam layer 3 and the base layer 4 When a hard board is selected as the substrate, it is interposed between the polyvinyl chloride foam layer 3 and the base layer 4, and the skin layer 1 and the polyvinyl chloride foam layer 3 are welded to the base layer 4 at the ends by welding. This is the configuration adopted.

Materials for the skin layer that can be used in the present invention include natural leather and synthetic leather.

The polyvinyl chloride foam used in the present invention includes polyvinyl chloride open-cell foam, which is available from Nippi Corporation under the trademark of Viniform.

Substrate layer materials that can be used in the present invention include hardboard and rigid polyvinyl chloride board.

The hot melt adhesive layer is interposed between the skin layer and the polyvinyl chloride foam layer at the end portion of the panel, and when a hard board is used as the base layer, the hot melt adhesive layer and the polyvinyl chloride foam layer are used. The skin layer, the polyvinyl chloride foam layer, and the substrate layer are welded together by being welded to the substrate layer. The hot melt adhesive layer material that can be used in the present invention includes hot melt tape.

A conventionally known technique can be used for the welding process for welding the ends of the panel.

The shape of the panel can be a polygon such as a triangle, a quadrangle, a pentagon and a hexagon, a circle, and a special shape, and a decorative pattern can be formed when the panels are laminated.

In the above interior decoration panel, an adhesive layer can be provided on the opposite surface of the base layer to which the foam layer is welded so that the interior decoration panel can be easily attached to the interior wall or the like. The adhesive layer can be selected from a foam double-sided adhesive sheet or a double-sided adhesive sheet. Alternatively, the base layer may be attached to the wall or the like using an adhesive.

【Example】

 Examples will be described with reference to the drawings.

FIG. 1 is a cross-sectional view of a panel of the present invention in which an adhesive layer 5 for adhering to a wall is applied. Reference numeral 1 is a skin layer, 2 is a hot melt adhesive layer, 3 is a polyvinyl chloride foam layer, 4 is a substrate layer, 5 is an adhesive layer, and 6 is a high-frequency weld pattern.

A high frequency welder is used as the weld.

FIG. 2 is a plan view when the shape of the decorative panel is a square. A high frequency weld pattern is formed on the edge of the panel.

[0017]

[Effect of device]

 INDUSTRIAL APPLICABILITY The present invention is configured as described above and can contribute to enrichment of interior decoration materials as a high-class interior decoration panel.
