Abstract

PURPOSE:To provide a panel large in sound transmission loss and excellent in sound insulation by putting a mixture of incinerated ash and binder on a surface layer material comprising wooden material, putting a surface layer material comprising decorative plates, pressurizing and heating it to form a core material, and integrally laminating the wood material and decorative plates on both surfaces of it. CONSTITUTION:A resin adhesive agent is applied onto the rear surfaces of a substrate 1 and a surface layer material 3. Next a mold 11 is put on a floor plate 15, and a mixture 12 of incinerated ash and binder is placed on it. Also the surface layer material 3 is put on the upper surface of the mixture 12 so that its adhesive agent coated side is made in contact with that upper surface. Then the floor plate 15 is put on a lower side plate 13 with an upper side hot plate 14 of the pair of upper and lower side hot plates 13 and 14 raised. 1 Subsequently the upper side plate 14 is lowered, and the area between the upper and lower side plates 13 and 14 is pressurized and heated to form a core material 2. In addition, a formed body on both sides of which the substrate 1 and the surface layer plate 3 are laminated is taken out and cured. Thus a whole panel is increased in density, and the panel excellent in sound insulation can be obtained.

According to the sound-insulating panel of the present invention, since the wood material is laminated on at least one surface of the surface layer material provided on both surfaces of the core material of the solid layer, the weight is added to the wood material. As a result, the density of the entire panel is increased, and the sound transmission loss is large and the sound insulation is excellent as compared with the conventional panel material made of wood alone.
When waste wood is used for incineration ash, it is possible to effectively use the waste wood that has been simply incinerated and used only for burying.
Further, when a thermosetting resin is used as the binder, it can be a panel material which can obtain water resistance and fire resistance.

According to the method of manufacturing a panel of the present invention, a mixture of incinerated ash and a binder is placed on a surface material made of wood material to a predetermined thickness, and a decorative plate is formed on the mixture. Since the surface layer material is placed and laminated, the laminate is pressurized and heated to solidify the mixture of the incinerated ash and the binder to form the core material of the solid layer, so that the core material is formed, Providing a method that makes it possible to extremely easily manufacture a panel material that has a large sound transmission loss and is excellent in sound insulation, in which at least one surface of the surface layer material on both sides of the core material is made of wood material, is extremely easy to manufacture using incineration ash. You can do it.

When waste wood is used for incineration ash, it is possible to effectively utilize the waste wood that has been simply incinerated and buried only when the thermosetting resin is used as the binder. It is possible to shorten the pressing time of the panel material as compared with the case of using.
