Hereinafter, a method of manufacturing artificial stone according to the present invention.

First, a luminous plate material is produced. In the present invention, the luminous plate material having a luminous effect can be made into a plate form by mixing the luminous pigment in a plate manufacturing process such as plastic, and also applying luminous paint containing a luminous pigment to one side of transparent plastic or glass or luminous It can be made by attaching sheet paper.

Next, two or more kinds of chips having different particle size distributions are manufactured. As chips, resin chips, glass chips, colored glass chips, natural stone chips, colored natural stone chips, and the like are used, and they are produced by dividing two or more kinds, for example, large chips and small chips in particle size.

Next, the chip produced above is blended with the artificial stone raw material. Artificial stone in the present invention is used as a building exterior material or interior material, it may be a cement artificial stone, or a resin artificial stone such as acrylic resin, unsaturated polyester resin, epoxy resin.

Next, the luminous plate member is fixed to an arbitrary position in the mold used for artificial stone molding.

Next, after inserting the artificial stone material in which the chip is blended into the mold, the artificial stone is molded while vibrating using a vibrator (vibrator).

The vibrator removes air bubbles contained in the artificial stone material and at the same time sinks a heavy chip into the bottom of the mold to maximize the attendance rate of natural stone exposed to the surface. That is, by increasing the exposure frequency of the chip on the surface it can form a more natural appearance.

The attendance rate is only about 50% when the vibrator is not used, but when using the vibrator, the attendance rate is increased by at least 65%, as much as 95%, usually 80 to 90%.

The vibration is preferably applied for 1 to 10 minutes at least 3,000 rpm or more.

When looking at the effects of vibration, first of all, when using two chips of different sizes, first, the larger chips sink to the bottom of the mold due to the vibration, and there is a space between the larger chips. The space between them becomes larger, and by filling the space with small chips, the bottom of the mold is filled tightly with the chip, so the attendance rate of natural stone can be increased.

In the press method, unlike the effect of applying vibration, the chip and the cement paste are simply pressed, thereby limiting the attendance rate of the chip.

Finally, after curing and demolding the molded artificial stone, the surface is polished to produce an artificial stone in which a luminous plate material formed in any design on the surface is integrated. Curing is carried out for at least 10 hours at a temperature of 40 to 50 ° C. and a condition of keeping humidity.

The color and design of the artificial marble and the shape and size of the luminous plate may be made of various products according to the user's taste or purpose of use.

According to another embodiment of the present invention, as described above, the luminous plate member may be manufactured by a method of inserting the luminous plate member after molding the artificial stone, rather than fixing the luminous plate member to a mold in advance and then molding and integrating it with the artificial stone. have.

Specifically, the method is different from the above-described method in the mold production step and the insertion order of the luminous plate member.

First, in the mold fabrication step, a mold having an embossed portion is formed to form an intaglio space into which a luminous plate material is to be inserted. In this case, the embossed portion may be formed integrally with the mold when the mold is manufactured or by attaching a plate member having the same shape as the luminous plate member to the mold.

Secondly, in the insertion order of the luminous plate member, the luminous plate member is inserted into the intaglio space formed after molding the artificial stone. That is, instead of inserting the luminous plate material in advance, the luminous plate material is inserted later after molding the artificial stone to have a space for the luminous plate material to be inserted.

In addition, there are two methods for inserting the luminous plate material, the first method is to make the concave part and the convex part symmetrically to the artificial stone and the luminous plate material and to fasten it without adhesive (see lego block), and the second method using the adhesive There is a method of adhering, the stone epoxy epoxy adhesive is preferably used at this time.

In the insertion order of the luminous plate member, it is preferable to insert the mold after the molding, since the position of the luminous plate member may be changed in the course of applying the vibration during artificial molding.

Example 1

Cement artificial stone was manufactured using natural stone chips.

First, a luminous paint was applied to one side of a 5 mmT transparent acrylic sheet and cut in an arrow shape to prepare a luminous plastic sheet.

Next, the prepared arrow-shaped luminous plastic sheeting material was placed in the center of the artificial stone molding mold. At this time, the transparent part of the luminous plastic sheet (the part not to be painted) was placed in contact with the mold.

Next, the cement paste used as the artificial stone binder was put into the mold. At this time, the cement paste used is 210 parts by weight of natural stone chips (large chips) having a particle size distribution of 3 to 9 mm to 100 parts by weight of cement, 90 parts by weight of natural stone chips (small chips) having a particle size distribution of 1 to 3 mm, 50 parts by weight of natural stone powder (100 to 350 mesh), 30 parts by weight of water, and 2 parts by weight of a PC-based water reducing agent.

Next, the cement paste is placed in the mold and vibrated at 3,000 rpm for 5 minutes to remove bubbles in the cement paste, while the natural stone chips are settled under the mold to maximize the attendance rate (80 to 90%). Cured for 12 hours under the condition that the temperature, 50 ℃ and humidity.

Next, after curing is completed, remove it from the mold, grind the back surface of artificial stone to a certain thickness using a normal abrasive stone, adjust the level and thickness, polish the surface, and then go through the cutting process to 400mmL × 400mmW × 17 mmT artificial stone was obtained.

Cured for 12 hours under the condition that the temperature, 50 ℃ and humidity.

Next, after curing was completed, the artificial stone molded in the mold was demolded. The demolded artificial molding was formed with an arrow-shaped intaglio of 5 mmT depth.

Next, a luminous paint was applied to one side of the 5 mmT transparent acrylic sheet and cut to the same size and shape as the arrow formed on the artificial stone molding to prepare a luminous plastic sheet.

Next, the luminous plastic sheet prepared above was inserted into the artificial stone molding. At this time, the surface coated with luminous paint was inserted in contact with the artificial stone.
