Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inorganic wallboard, and more particularly to a decorative inorganic wallboard.

[0002]

2. Description of the Related Art Conventionally, an inorganic building material molded mainly of cement has been widely used. This kind of building material can be mass-produced in the same quality in any shape depending on the application, and does not consume finite natural resources such as wood, so it is very convenient from the viewpoint of nature conservation. It has certain advantages. However, if these inorganic building materials are used as they are, the ground color is achromatic from light gray to dark gray and has poor designability, and also has the drawback of having water absorbability. It is usual to apply various colors to the surface. As these makeup coatings, as a makeup means for suppressing the surface gloss and providing a gentle surface color, a fine textured pattern such as a satin finish may be applied to the surface by spraying a paint such as a spray.

[0003]

However, in the case of the satin patterning using the spray as described above, it is necessary to precisely adjust various conditions such as the viscosity of the paint used, the spray pressure of the spray, and the condition of the spray outlet. In addition, when spraying the spray gun vertically downward on a horizontally placed wall plate, there are many failures due to the paint dripping and the like, and there is a drawback that manufacturing management becomes very troublesome. Further, in the case of applying a satin-patterned makeup by spray painting, it is difficult to give variability to the surface state because the fine paint particles adhered to the surface of the wallboard are easily rounded due to the surface tension when uncured. In addition, there are many paint particles that are scattered without adhering to the wall plate, resulting in poor efficiency. In addition, in order to avoid the color mixture when multi-color painting such as two-tone color to make the pattern on the wall board surface have variability, it is necessary to perform the next painting after at least the first touch drying,
In other cases, the use of masking is indispensable, and there is a drawback that painting becomes very troublesome.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an inorganic wall board which can easily obtain a satin-finished concavo-convex pattern on the surface and can easily perform a two-tone color finish. It was made.

[0005]

That is, the inorganic plate material according to the present invention is such that the fine granular solids 3 are uniformly dispersed on the undercoating surface 2 of the inorganic wall board 1 formed of a ceramic material, and the fine granular solids. A top coat coating 4 is applied to the surface of the wall plate including 3;

A second aspect of the invention is that the fine-grained solid 3 having a coloring treatment is uniformly dispersed on the ground-coated surface 2 of the inorganic wall board 1 formed of a ceramic material, and the wall containing the fine-grained solid is included. It is characterized in that the top coat coating 4 is applied to the plate surface,

In a third aspect of the present invention, a fine granular solid 3 which is colored in a different color is uniformly dispersed for each color on an undercoating surface 2 of an inorganic wall board 1 formed of a ceramic material, and A topcoat coating 4 is applied to the surface of the wall plate 1 containing the granular solids 3.

[0008]

In the inorganic plate material 1 of the present invention, the decorative material on the surface of the wall plate 1 is a fine granular solid 3 such as silica sand, colored silica sand, or microballoons, and the fine granular solid 3 is evenly dispersed on the base coating surface 2. Since it is applied to the coated surface and is covered with the top coat layer 4, fine irregularities of fine solid particles 3 appear on the surface of the wall plate 1 to obtain a very delicate satin-like irregular pattern. Further, the fine granular solid 3 is reliably held by the base coating 2 and the top coat layer 4 and is not peeled off.

Further, if a transparent coating material is used for the top coat layer 4, the color of the fine granular solid 3 appears directly on the surface, so that various colored makeups can be made by using colored sand particles, and in this case, coloring of different colors is possible. It is possible to easily apply a colored pattern of two or more colors by separately or separately spraying sand particles.

[0010]

Embodiments of the present invention will be described below.

(Example 1) The surface of the fiber-reinforced cement board 1 was coated with three kinds of paints 2 of urethane paint, epoxy paint, and acrylic paint so as to be about 100 g / m ² each, and the paint was not dried. 150g of No. 5 silica sand 3 on average
It was evenly sprayed at a ratio of / m ² , and then the base paint was dried. Next, a top coat 4 was applied to the surface with an acrylic paint containing a coloring pigment, an acrylic silicone paint, and a fluorine-based paint so that the amount of each was about 100 g / m ² . When the surface was observed after drying, it was observed that the surface had fine irregularities like the surface of fine sandpaper.

(Example 2) Coating was carried out in the same manner as in Example 1 except that red colored silica sand was used as the fine granular solid 3 in Example 1 and a transparent paint was used as the top coat paint 4. When the surface was observed after drying, it was observed that the surface had a fine uneven pattern like the surface of fine sandpaper, and that the color of the colored sand grains 3 appeared vividly on the surface.

(Example 3) Red colored silica sand and black colored silica sand were used as the fine granular solid 3 in Example 1, and after undercoating 2 was carried out in the same manner as in Example 1, the coating was not dried. Then, red silica sand was applied in a spot-like pattern, and then black silica sand was evenly applied to the surface. After the base paint 2 has dried, the surface is lightly brushed to remove the black silica sand just on the red silica sand to make the red portion stand out, and then a transparent paint is used on the surface to top coat as in Example 1. 4 was given.

When the surface was observed after drying, the surface had a fine uneven pattern like the surface of fine sandpaper, and black and red color-coded colors by the colored sand grains 3 appeared vividly on the surface. Was observed.

(Embodiment 4) A fiber-reinforced cement board 1 having a surface uneven pattern formed by forming brick-like vertical and horizontal joints on the surface, and about three kinds of paints 2 of urethane paint, epoxy paint and acrylic paint on the surface, respectively. After applying a base coating to 100 g / m ² and drying it once, apply the same paint as above to the convex surface of the fiber reinforced cement plate 1 excluding the joint groove at the same ratio with a roll coater, While the paint was not dried, No. 5 silica sand 3 was uniformly sprayed at an average rate of 150 g / m ² , the silica sand 3 retained in the joint groove was removed by air injection, and then the paint was dried.

Next, an acrylic paint containing a coloring pigment on the surface, an acrylic silicone paint, and a fluorine-based paint
The top coat 4 was applied to the entire surface of the fiber-reinforced cement board 1 including the joint groove so as to be 100 g / m ² . After observing the surface after drying, a fine uneven pattern appears on the convex surface like the surface of fine sandpaper, and the surface state of the joint groove and the convex surface is clearly different. Was observed.

(Comparative Example) The acrylic emulsion paint used in Example 1 was applied to the surface of a fiber reinforced cement plate by airless spraying at a rate of 300 to 450 g / m ² so that the paint was in a particulate form, and was dried and cured. Then, the same top coat paint as in Example 1 was applied on the surface. When the surface was observed after drying, the unevenness of the surface was considerably rough and a uniform feeling was not obtained.

Next, when the inorganic wallboards 1 obtained in Examples 1 to 3 and Comparative Example were left outdoors for 1 year under the condition of exposure to the south surface, the surfaces of Examples 1 to 3 did not change at all and the surface was not changed. There was no separation of the particles even when the palm was strongly pressed against and rubbed.

[0019]

As described above, according to the inorganic wall plate 1 of the present invention, the unevenness of the surface makeup becomes the unevenness of the fine granular solid 3 as it is to form a satin-like uniform unevenness pattern, and an excellent design feeling can be obtained. Moreover, since the unevenness pattern on the surface can be obtained only by spraying the fine granular solids 3, it is easy to manufacture, and it is possible to provide a plate material having an excellent aesthetic appearance at low cost.
