た。 In addition, the manufacturing method is to place a thermoplastic synthetic resin plate in a mold, arrange natural fine stones on top of it, and heat it to integrate the synthetic resin plate and fine stones, making it easier to work. , manufacturing efficiency is poor, making it unsuitable for mass production and resulting in high costs. Also, since different molds must be used for each size,
Workability becomes worse and equipment costs increase. Furthermore, due to mold restrictions, the dimensions of the decorative board are limited to a small range, which limits its uses.
（発明の目的）
そこで第１発明では、機械的および熱的強度に

A long fine stone sheet body in which a thermoplastic synthetic resin sol is applied to an almost even thickness on a release sheet that is continuously fed in a fixed direction, and a large number of natural fine stones are temporarily fixed on this sol layer. After cutting this fine stone sheet body and peeling off the release sheet to obtain a fine stone sheet of a certain length, a transparent or translucent cover made of thermoplastic synthetic resin is placed on top of this fine stone sheet. Place the sheet under the fine stone sheet,
A colored sheet made of thermoplastic synthetic resin, a reinforcing sheet made of non-thermo-stretchable material such as glass non-woven fabric, and a shape-retaining sheet made of thermoplastic synthetic resin are laminated in order from the top to form a laminate. By heating and pressurizing the laminate, the fine stones in the fine stone sheet are embedded and fixed on the surface of the sheet base material, and the front side of the fine stone sheet is covered with a cover sheet, and the lower layer of the fine stone sheet is provided with a colored sheet, a reinforcing sheet, A decorative board is obtained by laminating and fixing shape-retaining sheets.

圧される。 In the heating and pressurizing process shown in FIG. A PVC colored sheet 6 for producing a different color (color), a reinforcing sheet 7 made of a non-thermo-stretchable material (a material that does not expand or contract with temperature changes) such as glass non-woven fabric made of glass fiber or asbestos, and the overall A shape-retaining sheet 8 made of PVC, which is the lowest layer to ensure shape-retaining properties and rigidity, is laid on top of the other, and a transparent or semi-transparent cover sheet 9 made of PVC is laid on top of it to form the laminate P1 . configured. And this laminate P 1
A cushion material 10 is placed on the upper surface (upper surface of the cover sheet 9), and these metal plates 11, such as iron plates,
The same metal plate 11, 1 is sandwiched between 11 and 11.
1 and is heated and pressurized by a heating and pressurizing means (not shown).

At the same time as the sheet base material 1a softens, the fine stones 1b...
is pressed against the sheet base material 1a, so that the fine stones 1b... are pressed against the base material 1a as shown in FIG.
It is embedded in a and is permanently fixed. In this case, since the cushion material 10 applies pressure evenly over the entire surface of the fine stone sheet 1 along the unevenness thereof, the unevenness on the surface of the fine stone sheet caused by the fine stones 1b remains as is even after the pressure is applied. In other words, the fine stones 1b are not completely immersed into the sheet base material 1a due to the pressing force, and the surface does not become smooth, so that the natural visual and tactile sensation of a rugged gravel wall can be obtained.

However, if a smooth surface is more suitable for the purpose, pressure may be applied directly with the metal plate 11. Further, the adhesive film 5 may be used only when it is desired to strengthen the thermal adhesion between the fine stone sheet 1 and the colored sheet 6. On the other hand, in the manufacturing process of the fine stone sheet 1, the means for applying PVC sol to the release sheet 2, and the fine stone 1b to the PVC sol layer 1a 1 .
The means for supplying... may be changed as appropriate other than the means using the hoppers 3 and 4 shown in the above embodiment. Furthermore, as the thermoplastic synthetic resin used for the sheet base material 1a of the fine stone sheet 1, etc., materials other than PVC may be used.

粧板の製造方法。[Scope of Claims] 1 A fine stone sheet is constructed by embedding a large number of natural fine stones in a transparent or translucent sheet base material made of a thermoplastic synthetic resin, and a fine stone sheet made of a thermoplastic synthetic resin is formed on the front side of the fine stone sheet. A transparent or semi-transparent cover sheet made of A decorative board characterized in that the sheets are stacked one on top of the other in order from the fine stone sheet side, and each is integrally heat-fused to the fine stone sheet. 2. On a release sheet that is continuously fed in a certain direction, a thermoplastic synthetic resin sol is applied to an almost even thickness to form a sol layer, and a large number of natural fine stones are supplied onto this sol layer. These are heated to gel the sol layer, and further cooled and solidified to form a long fine stone sheet body in which a large number of natural fine stones are temporarily fixed on the surface of a transparent or translucent sheet base material. After cutting this fine stone sheet body and peeling and removing the release sheet to obtain a fine stone sheet of a certain length, a transparent or translucent cover sheet made of thermoplastic synthetic resin is placed on top of this fine stone sheet,
A colored sheet made of thermoplastic synthetic resin, a reinforcing sheet made of non-thermo-stretchable material such as glass non-woven fabric, and a shape-retaining sheet made of thermoplastic synthetic resin are superimposed on the bottom of the fine stone sheet in order from the top. By constructing a laminate and heating and pressurizing this laminate, the fine stones in the fine stone sheet are embedded and fixed on the surface of the sheet base material, the front side of the fine stone sheet is covered with a cover sheet, and the lower layer of the fine stone sheet is A method for producing a decorative board, which comprises obtaining a decorative board by laminating and fixing a colored sheet, a reinforcing sheet, and a shape-retaining sheet.
