Abstract

PURPOSE:To enhance design, resistance against freezing and melting, anti- weatherability, durability, and produciability by baking decoration clay fast on the decoration surface of a non-combustive construction material, dispersing therein granular, colored, and baked artificial aggregate left to natural coloring, and by permitting them to consolidate together. CONSTITUTION:An aggregate 2 is recessed or in the decoration surface of a mother material 1 consisting of a non-combustible compound which is dried, baked, and cooled, or otherwise the surface is covered with the aggregate 2 with the aid of frit 3. The aggregate 2 consists of particles of clay, which have undergone baking process into spheres, provided with natural coloring depending upon the fashion of baking. As lysine pattern can be formed as any desired on the decoration surface of porcelain plate, the design will be excellent.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method of extruding noncombustible building materials, such as clay, into a plate shape.
The invention relates to hard wall materials and decorative materials that are then dried and fired.

[Conventional technology]

Cement, gypsum board, calcium carbonate board, calcium silicate board, slate board, ALC board, clay fired tiles, roof tiles, and exterior wall materials are known as noncombustible building materials. , All decorative surfaces were coated with paint, enamel, and metal plates.

[Problem to be solved by the invention]

However, while the design and texture of this type of building material are improved to a certain extent, the coating lacks durability and natural feel, and the enamel has limitations on color, film thickness, and shape. It had the disadvantage of not cutting easily and lacking durability and weather resistance.

Furthermore, these materials had poor freeze-thaw resistance and were at risk of cracking and peeling off within a few years.

[Means to solve the problem]

In order to eliminate these drawbacks, the present invention creates an unprecedented design by interspersing and integrating granular colored fired artificial aggregates made by firing decorative clay to naturally develop color on the decorative surface of noncombustible building materials. properties, freeze-thaw resistance, weather resistance, and durability.
To provide a noncombustible building material that is cost-reduced, highly productive, and free from flaking of ricin-patterned granules.

〔Example〕

An embodiment of the noncombustible building material according to the present invention will be described in detail below with reference to the drawings. That is, Fig. 1 (al~(C)
1 is a partially cutaway explanatory diagram showing the structure of the above-mentioned noncombustible building material, in which 1 is a main body, 2 is a granular colored fired artificial aggregate (hereinafter simply referred to as aggregate), and 3 is a glaze. To explain further,
Main body 1 is made of a non-combustible composition, and contains one or more main components such as pottery stone, feldspar, and clay from various other sources, or if necessary, alkali-resistant water-soluble polymers, asbestos, silica, and glass. The nonflammable composition is made of a mixture of one or more of fibers, carbon fibers, whiskers, chamotte, wollastenite, etc., and is extruded through a die 4 as shown in FIGS. The product is made by drying, firing, cooling, etc.

The aggregate 2 is a spherical granule made by granulating clay or the like and baking the granule, and has a particle size of about 0.5 to 41 mφ. This aggregate 2 has a natural color depending on the raw clay material and firing conditions, and is formed so that the original color will not change even if it is re-fired at around 1300°C.
Until now, the color change caused by firing caused a slight change in the color tone, which caused an increase in yield, productivity, and cost, but by covering the decorative surface of the main body 1 with aggregate 2, the change in color tone due to firing is eliminated. Further, the distribution of the aggregate 2 can be arbitrary, and it can be used to cover the entire decorative surface of the main body 1, to be scattered, or to be formed into a predetermined pattern using a screen.
As shown in Fig. al, the glaze 3 is partially buried in the main body 1 and pressed with a roller etc. to exert an anchor effect, or as shown in Fig. fb1, the glaze 3 is used as an adhesive to form the bone. By integrating materials 2 or as shown in the IC1 diagram,
The glaze 3 can also be applied after pressing the aggregate 2 with a roller or the like. Of course, the placement of the aggregate 2 and the application of the glaze 3 are performed before firing. The material for glaze 3 is lead glaze, alkali glaze, alkali-lime glaze, lime glaze, feldspar glaze, boric acid glaze, etc., and it is vitrified by firing and noncombustible building material A.
Formation of decorative surface (color, pattern, etc.) in , aggregate 2 as main body 1
It functions as an adhesive layer for bonding, and depending on the firing temperature, it becomes hard, glossy, and has high reflectance.
