Description

[Detailed Description of the Invention] The present invention relates to a tile-like decorative board made mainly of rock wool.

Traditionally, tiles have been made by plasticizing clay, applying glaze, and firing. However, due to the large heat shrinkage of tiles, each side is 30 cm.
Larger versions have poor dimensional accuracy, which makes them difficult to manufacture, and they are also heavy, which causes problems such as difficulty in handling during construction when they adhere to the substrate. be.

The present invention was devised in view of these problems, and it is an object of the present invention to provide a decorative board that is mainly made of rock wool and that can be formed into large plates and has a tile-like appearance that can be used as a substitute for conventional ceramic tiles.

The embodiments of the present invention will be explained with reference to the drawings: 1
is a rectangular rock wool main body molded plate, which has square tile-shaped bulging protrusions 2, 2 integrally formed on its front side, and the peripheral wall 3 of the tile-shaped bulging protrusions 2 extends outward toward the lower end. The peripheral wall 3 is formed into an inclined surface slanting in the opposite direction, and the lower end peripheral edge of the peripheral wall 3 is connected to a square frame-shaped flat part 4.

5 is an undercoat layer applied to the entire surface of this rock wool three-dimensional molded plate 1. This undercoat layer preferably coats the surface layer and at the same time forms a waterproof layer on the substrate.

6 is an uneven pattern provided on the surface of the undercoat layer 5, and the undercoat and a different color paint are sprayed in granules to form the tile-like protrusions 2 and peripheral wall 3 of the rock wool three-dimensional molded board 1.
The granular protrusions 6a are scattered on the surface of the frame-shaped flat part 4, and the granular small protrusions 6b have a different color from the granular protrusions 6a and have a smaller diameter than the granular protrusions 6a. The small protrusions 6b are randomly scattered over the entire surface of the three-dimensional rock wool plate 1 so as to overlap with the large diameter granular protrusions 6a, and have an appearance similar to glazed ceramic tiles.

The rock wool three-dimensional molded plate 1 is formed to have a substantially uniform thickness over the entire surface including the bulging convex portions 2. Therefore, on the lower surface side of the bulging convex portions 2, there is a space corresponding to the bulging height. 7 is formed.

Such a rock wool molded plate 1 can be obtained as follows.

First, as shown in FIG. 4, a thermosetting resin such as phenolic resin is applied to a breathable mold 11 made of metal or steel, which is formed in the same shape as the mold surface of the mold to be used later. The molding material 12 to which is added is deposited to a constant thickness by blowing air or the like. At this time, by suctioning air from the lower surface side of the breathable mold 11, a laminate 13 having a substantially uniform thickness is formed.

Next, the fifth layer is stacked on the breathable mold 11.
As shown in the figure, a molded plate 1 is obtained by placing the mold plate between a pair of upper and lower molds 14 and 15 and performing heating and pressure molding.

Furthermore, it is also effective to press-form the molded plate 1 using a secondary molding die, if necessary.

Rock wool three-dimensional molded plate 1 obtained in this way
As described above, the tile-shaped bulging convex portion 2, its peripheral wall 3, and frame-shaped flat portion 4 are formed to have a substantially constant thickness, and the space 7 is formed on the back side of the tile-like bulging convex portion 2. There is.

As mentioned above, this three-dimensional molded board 1 is mainly made of rock wool, with thermosetting resin mixed therein as a binder, but in addition to this, lightweight aggregates such as perlite, fillers such as tankal, and reinforcing materials are also used. You may also add vegetable fibers and the like.

Next, this three-dimensional molded board 1 is coated with an undercoat depending on its surface condition, and the surface of the molded board is coated with a uniform coating film. It is provided to attach the following information.

Moreover, an uneven pattern 6 applied to the surface of the undercoat layer 5
If the granular coating is applied in just one layer, that is, only the granular protrusions 6a, there will be little change;
By applying the granular protrusions 6b with a smaller diameter than the granular protrusions 6b and making them double or more, a complex pattern can be formed and a surface rich in elegance can be formed.

In particular, a glaze-like appearance similar to that of ceramic tiles can be obtained by varying the size of the granular protrusions, combining colors, and adding speckled colors.

In the above embodiment, the shape of the three-dimensional rock wool plate 1 is rectangular, and two square tile-shaped bulges 2, 2 are provided in the length direction. It is desirable that the width of the flat portion between the opposing wall surfaces of the bulging convex portions 2 is twice the width of the outer circumferential flat portion of the molded plate 1; however, in the present invention, such a bulging convex portion 2 The number is not limited, and one or more may be provided.

In this way, the present invention has an uneven pattern 6 made of paint on the surface of the rock wool three-dimensional molded plate 1, which has a frame-like flat part 4 provided at the lower end of the peripheral wall 3 of the tile-like bulging convex part 2.
Since it is molded using rock wool as the main raw material, it is possible to obtain a large-sized tile-like decorative board without firing, etc. Even when formed, dimensional accuracy is good because uneven shrinkage due to firing does not occur unlike ceramic tiles, and a space 7 is formed on the back side of the tile-shaped bulging convex part 2, so that the entire surface is almost uniform. Because it is formed thickly,
It is lightweight and easy to handle, and can improve construction workability.

Furthermore, even though it is made of rock wool, the surface of the molded plate 1 can be painted with an uneven pattern 6 to give it the same appearance as tiles, and since it is made of rock wool, it can be easily cut. As described above, it has good workability, and since it can be obtained by press molding, unlike drilling molding with a grinder etc., fibers are not cut, so a product with high strength can be obtained. Furthermore, by changing the press pressure, decorative laminates with various specific gravities can be obtained, from those that require strength to those that require light weight, and by changing the mold material, it is possible to create freely shaped laminates. .
