The present invention relates to a method for producing artificial stone and artificial stone by hardening the stone powder composed of a core wood board.

Wood or marble, which is widely used as a conventional building interior material or a material of furniture or crafts, is limited in its use range or work (processing) range due to durability or weight constraints.

In other words, in the case of wood, the surface strength is weak and durability deterioration is caused by the penetration of water or moisture, and a separate treatment means for strengthening the strength and durability must be performed in parallel, and in particular, because the color or pattern depends only on the wood grain. It was difficult to express monotonous and various colors and patterns.

In addition, in the case of marble, the weight is heavy, so it is difficult to handle and inconvenient to process, and in the case of artificial marble, the manufacturing method is difficult, and the weight weight problem is not overcome.

The present invention provides an artificial stone including a wooden board to reduce the weight of the artificial stone and to harden by molding the stone powder in the form of dough can be solidified processing and assembly can be implemented in any model and pattern (characters, pictures, It is possible to realize paintings of various colors and pattern of natural marble by making petrified sketches, and to provide artificial stone and its manufacturing method to secure the durability of hardened stone powder, improving the surface strength, gloss and moisture. Hereinafter, the artificial stone of the present invention and a manufacturing process thereof will be described with reference to FIGS. 1 to 6 as follows.

In other words, the particle size of 80 to 100 mesh dolomite, quartz, quartz stone powder and pigment, and ananol (AN) and xyrene (XY) solvent, and anan (AN) (cyclo hexanone) and xylene ( XY) is mixed at a ratio of 1: 1, and then the pigment of the required color is dissolved in ananone (AN) and xylene (XY) solvents.

At this time, a small amount of adhesive leather 500 (vinyl ink) was dissolved, and the mixture of the pigment and the solvent was added with stone powder, followed by mixing, followed by drying for 6 to 8 hours to produce colored stone powder (1).

Then, a drawing board (2) (2.5 mm thick paper board) of yellow cardboard paper, adhesive, colored stone powder (1), and a brush are drawn, and the desired drawing (3) is drawn on the drawing board (2), and then the drawing (3) Apply the adhesive with a brush.

Then, the colored stone powder (1) is sprayed onto the adhesive coated sketch (3), the colored stone powder (1) is bonded to the adhesive and adhered to the sketch (3) to complete the stone powder painting (petrification), after which Tap (2) lightly to drop and remove colored stone powder sprayed on the part other than the sketch (3) coated with adhesive. In this way, the colored stone powder (1) attached to the sketch (3) is applied by applying vibration to the pattern plate (2). Spread evenly.

If you cut out the sketch (3) as described above with scissors or a knife, you can put a picture in the artificial stone to be produced later.

That is, Figure 2 (a) to (d) and Figure 3 shows the artificial stone manufacturing process of the present invention, the sketch (3) produced in the above process and the natural stone pattern configuration method.

First, as shown in (a) of FIG. 2, a mold 4 is manufactured. The shape of the mold 4 is a frame of a desired shape based on the final marble shape. The embodiment represented in the drawing is a rectangular frame. .

Then, a mold release agent such as silicone oil is uniformly applied to the inside of the mold frame 4 using a brush, and then a thermoplastic resin (transparent resin such as epoxy, epomica, homica, etc.) is applied to the container 5. The mixture of 1 was added and mixed, and the main hardener and the colored stone powder in FIG. 1 were mixed at a ratio of 1: 1 to 1: 5 to prepare a stone flour dough (6).

Subsequently, the unbaked artificial stone 8 as shown in (c) of FIG. 2 is manufactured by applying the stone powder dough 6 to the surface of the wooden board 7 as shown in FIG. The sketch 3 produced in FIG. 1 is coated with an adhesive and attached to the top surface of the artificial stone 8 in an uncured state as shown in FIG.

At this time, apply the stone powder dough (6) to the wooden board (7) as shown in (b) of FIG. 2 and set it to 45 ° inclined as shown in FIG. 3, and the stone powder dough (6) flows due to its own weight and viscosity. As it falls, natural patterns are formed.

Alternatively, the powdered dough (6) is poured into the mold mold (4) and the mold mold (4) is inclined to be inclined so that the pattern is formed in advance, and the wooden board (7) is put into the mold mold (4) and then embedded into the stone dough (6). do.

As such, when the coated sketch 3 is attached to the top surface of the uncured artificial stone 8 formed with natural patterning and starts to harden, the artificial stone 8 is turned upside down in the mold frame 4 as shown in FIG. Put it in close contact with the bottom of the mold (4).

Subsequently, when the stone powder dough 6 is applied to the rear portion of the wooden board 7, the wooden board 7 is completely embedded in the stone powder dough 6, whereby the uncured artificial stone 8 is formed by the mold 4.

After 5-6 hours at room temperature curing, artificial stone (8) is completely cured, after which the cured artificial stone is separated from the mold (4) and wipe the surface with a dry cloth.

At this time, the artificial stone is easily separated from the mold 4 by the release agent applied in the mold 4.

Subsequently, the polished (surface) treatment of the artificial stone cured using the abrasive stone to the necessary couple is completed to maintain the gloss, the pattern, and the desired color.

After that, cut to the required dimensions, drill a hole using a drill, and fix it using a screw, etc. The seat of the screw is filled with stone powder to complete the product.

That is, Figure 4 is a cross-sectional view of the artificial stone (9) completed through the above process, the hardened stone powder dough (6 ') has a color, and the surface of the natural pattern and sketches composed of petrification by the wooden board (7) inside Inherent.

This wood board 7 reduces the weight of the artificial stone 9.

In addition, the wood board 7 is made of a lumber 10 as shown in (a) of FIG. 5, and the artificial stone 9 is formed by covering the upper and lower surfaces with the plywood 11 to form a space 12 therein. To further reduce the weight.

The artificial stone manufactured as described above is lightweight, easy to cut, and has various colors, patterns, and patterns of natural marble, so it is more widely used than wood, such as sinks, crafts such as furniture, interior and exterior decorative signboard wall materials, and architectural flooring. Take advantage.

As described above, according to the present invention, the molding can be freely formed in any shape, and the surface strength and gloss are excellent, so that the artificial stone of elegant material can be provided. There is.
