るものである。[Detailed Description of the Invention] The present invention relates to a decorative board in which a vinyl chloride sheet is adhered to the surface of a styrene resin, and an object of the present invention is to provide a decorative board in which the vinyl chloride sheet is adhered in good condition. It is.
塩化ビニールシートはその表面に木目などを印刷し、

下本発明の実施例について図面を参照して説明する。However, if a styrene-based resin such as ABS resin or polystyrene resin is used instead of a wooden board and a vinyl chloride sheet is pasted on top of it, the plasticizer in the vinyl chloride sheet will migrate to the styrene-based resin, resulting in adhesive bonding. It is said to be of no practical use because its strength weakens and it peels off. The present invention makes it possible to adhere a vinyl chloride sheet to a styrene resin by devising an adhesive. Examples of the present invention will be described below with reference to the drawings.

れについて説明する。The sheet-like adhesive 2 has three layers, in which acrylic resin adhesives 2b and 2c are applied to both sides of a thermoplastic resin sheet 2a, such as a nonwoven fabric, to which a plasticizer does not transfer. Acrylic resin adhesives are advantageous because they have good compatibility and adhesion with both vinyl chloride and styrene resins. Further, since the sheet 2a made of non-woven fabric does not allow the plasticizer in the vinyl chloride sheet 1 to pass through, there is no transfer of the plasticizer, and peeling of the vinyl chloride sheet 1 hardly occurs. FIG. 2 shows a method for making a decorative board, which will be explained below.

者を重ねてシート状に構成しておくと便利である。A lower container 4 and an upper container 5 are provided, and a heater 6 is provided in the upper container 5.The opening of the upper container 5 is covered with a vinyl chloride sheet 1, and the opening of the lower container 4 is covered with a sheet adhesive 2. 1 and the adhesive 2 are made to face each other, and the upper container 5 and the lower container 4 are brought together. Next, remove the air in the direction of the arrow and remove the containers 4 and 5.
The inside is evacuated, and then air is introduced only into the container 5. Then, since the sheet 1 has been heated by the heater 6 and has become soft, it is pulled downward by the pressure of the air and tightly adhered to the surface of the molded product 3. In the above embodiment, the sheet 1 and the adhesive 2 are separated, but it is convenient to stack them to form a sheet.
