Abstract

PURPOSE:To manufacture a building board having recessed and projected pattern inexpensively with good production efficiency, by a method wherein a surface member, conveyed by a conveyer, is pressed by a roll, provided with recesses and projections on the outer peripheral surface thereof, to provide it with the recessed and projected pattern, then, the material of foam is supplied on the surface member to form a foamed body layer. CONSTITUTION:A surface member 2 such as a vinyl chloride resin sheet, an aluminum sheet or the like, which is reeled by a reeling roll 11, is unwound between the guides 9 of a conveyer 1 to convey it. The surface member 2 is pressed by a roll 4, which provides the member 2 with recesses and projections, to form recessed and projected pattern 5. Next, the material 6 of form such as phenol resin containing a foaming agent is supplied from a supplying nozzle 13 to the surface member 2 to foam it by the heat of a caterpillar 8 whereby a foamed body layer 7 is formed on the rear side of the surface member 2. At the same time, a backup sheet 16 is pressed against the foamed body layer 7 for bonding. Accordingly to this method, the recessed and projected pattern may be provided continuously and the productivity of the title board may be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method of manufacturing a building board having an uneven pattern on its surface.

[Background technology] Conventionally, uneven patterns have been applied to building boards by embossing presses using molds, but press molds are expensive, and if the uneven pattern changes, it is necessary to make a new mold. was there. In addition, it was a batch process and had low productivity.

[Objective of the Invention 1 The present invention has been made in view of the above circumstances, and its purpose is to provide a manufacturing method for building boards having an uneven pattern at low cost and with high production efficiency. It's about doing.

DISCLOSURE OF THE INVENTION 1 The method for manufacturing a building board according to the present invention comprises rolling a surface material 2 conveyed by a conveyor 1 into a roughening roll 4 having an uneven surface 3 on the outer peripheral surface.
The method is characterized in that the surface material 2 is pressed to give an uneven pattern 5 to the surface material 2, and then the foam raw material 6 is supplied to the surface material 2 provided with the uneven pattern 5 to form foam waste 7 on the surface material 2. With this configuration, the above object can be achieved. Since the textured pattern 5 is applied to the surface material 2 by the textured roll 4, the textured pattern 5 can be continuously imparted, and by changing the shape of the textured surface 3 of the textured roll 4, various shapes can be created. It is possible to provide an uneven pattern 5.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The conveyor 1 is a lower conveyor of a double conveyor as shown in Figs. 3 and 4, and guides 9 are provided protruding from both sides of iron caterpillars 8 to prevent the caterpillars 8 from misaligning when the id 9 is open. A belt 10 made of nylon or Teflon is arranged, and a surface material 2 such as a vinyl chloride resin plate or an aluminum plate wound on a take-up roll 11 is placed on the side 9 of the conveyor 1. The surface material 2 is rewound, arranged, and conveyed. An unevenness imparting roll 4 is installed above the conveyor 1, and by passing the surface material 2 between the unevenness imparting roll 4 and the conveyor 1, the surface material 2 is transformed into an unevenness imparting roll. 4 to form an uneven pattern 5 on the surface material 2.

The uneven surface 3 of the uneven surface imparting roll 4 is formed by applying an adhesive or a pressure-sensitive adhesive to the outer peripheral surface and temporarily fixing the granules 12 thereon.

Since the grains 12 are only temporarily fixed, to change the shape of the uneven surface 3, peel off the grains 12 and insert grains 12 of a different shape.
This can be done easily by pasting the . Next, a foam raw material 6 such as phenol resin or urethane resin containing a foaming agent is supplied to the surface material 2 from a supply nozzle 13 installed above the conveyor 1 . This foam raw material 6 is foamed by the heat of the caterpillars 8 of the conveyor 1 to form a foam layer 7 on the back side of the surface material 2. At the same time, a backup sheet 1 such as aluminum foil is removed from the take-up roll 15.
6 is rewound, and the backup sheet 16 is pressed and adhered to the foam layer 7 by the upper mold conveyor 14 installed above the conveyor 1. In this way, the female fruit 17 and male fruit 18 are continuously formed as shown in FIG. 5, and the uneven pattern 5 is formed.
Build a building board A with .

[Effect of the invention 1 In the present invention, an uneven pattern is applied to the surface material by pressing the surface material conveyed by a conveyor with an uneven surface imparting roll having an uneven surface on the outer peripheral surface, and then an uneven pattern is applied to the surface material. Since a foam material is supplied to the surface material to form a foam layer on the surface material, an uneven pattern can be continuously imparted, increasing productivity, and the shape of the uneven surface of the uneven surface can be changed. By doing so, uneven patterns of various shapes can be provided.
