The present invention relates to an artificial marble and a method for manufacturing the same, and more particularly, to an artificial marble having a variety of appearances and high-quality natural texture, such as natural marble by the reaction of unsaturated polyester resin, pearl and wax, and a method for producing the same. will be.

Natural marble, which is formed by recrystallization after lime or dolomite is subjected to contact or wide-area metamorphism, has a unique multicolored pattern and gloss when polished, and is used as interior and exterior materials of buildings. However, the building material made of natural marble has a problem that its use is limited because its thickness is usually 10 mm or more, its volume, weight, and price are high. Thus, although the price is cheaper than natural marble, much effort has been made to manufacture artificial marble which can give a feeling like natural marble. However, artificial marbles with various appearances and luxurious textures such as natural marble are still developed. It's not happening.

Accordingly, the present inventors have completed the present invention by developing an artificial marble having excellent processability and light weight while having various appearances and luxurious textures such as natural marble by using unsaturated polyester resin, pearl and wax.

It is an object of the present invention to provide an artificial marble composed of a marble pattern / pattern color layer consisting of unsaturated polyester resin, pearl and wax on a panel and one side thereof, and having various appearances and luxurious textures such as natural marble.

Another object of the present invention is a method of manufacturing artificial marble having a variety of appearance and luxurious texture, such as natural marble,

Blocking the edge of the upper surface of the panel to form a space having a desired coating thickness; Treating the space with a mixture of unsaturated polyester resin and pearl and wax; To provide a method of manufacturing artificial marble comprising the step of removing the blocking of the edge after curing.

In order to achieve the object of the present invention, artificial marble having various appearances and luxurious textures, such as natural marble composed of a marble pattern / pattern layer of unsaturated polyester resin, pearl and wax, is provided on the panel and one side of the panel. do.

In the present invention, the panel generally includes panels such as MDF, boards, acrylic, low-quality marble, and backlight, which are used as building materials. There is no limitation on the size or thickness of the panel, but it is appropriately used considering the ease of manufacture.

Unsaturated polyester resin is used in building materials, a conventional two-component or three-component unsaturated polyester resin can be used, which can form a coating film of a certain thickness upon curing, non-wax type unsaturated polyester resin is preferred. . Unsaturated polyester resins may also be used to improve physical properties such as hardness, dimensional stability, shrinkage and / or gloss.

Pearl is usually a kind of pigment added to create a beautiful color in furniture paints, there are pearl pearl, golden pearl, copper pearl, silver pearl and the like depending on the color generated. In the present invention, one or more pearls are used, and marble surfaces of various colors may be created according to the type of pearls used and the pigment mixing ratio.

Wax may be used for furniture wax. Preferably, water-based solvents and silicone oil-based waxes can be used.

In general, wax has no compatibility with unsaturated polyester resins, and therefore, prior wax treatment has been contraindicated when unsaturated polyester resin paints are used in building materials. However, according to the present invention, when a drop application is applied to an unsaturated polyester resin (drop application), the reaction with the unsaturated polyester resin occurs around the wax drop, and various and luxurious appearances like unexpected natural marble (shape / pattern / Color) artificial marble was formed.

In the artificial marble according to the present invention, 100 parts by weight of unsaturated polyester resin is preferably contained in 0.1 to 2.5 parts by weight of pearl and 0.01 to 0.2 parts by weight of wax.

If the pearl is less than 0.1 parts by weight or more than 2.5 parts by weight, it is difficult to form a luxurious pattern / colored marble. If the wax is less than 0.01 part by weight or greater than 0.2 part by weight, it is also difficult to form a luxurious pattern / colored marble.

In addition, the artificial marble according to the present invention may further include other pigments, such as red, yellow, etc., which are generally used in paints as needed. The amount of the pigment may vary depending on the color of the desired marble, but the general pigment is preferably included in an amount of 0.001 to 0.05 parts by weight based on 100 parts by weight of the unsaturated polyester resin. If the pigment is 0.001 parts by weight or less, it is difficult to exert the effect of the pigment, and if it exceeds 0.05 parts by weight, too dark marble pattern / color may be formed.

In order to achieve another object of the present invention, as a method of manufacturing artificial marble having a variety of appearance and luxurious texture, such as natural marble,

i) blocking the edge of the upper surface of the panel to form a space having a desired coating thickness;

ii) treating 0.1-2.5 parts by weight of pearl and 0.01-0.2 parts by weight of wax to 100 parts by weight of unsaturated polyester resin in the space;

iii) to provide a method of manufacturing artificial marble comprising the step of removing the blocking of the edge after curing.

In the production process according to the invention, the panels, unsaturated polyester resins, pearls and waxes are as defined above.

In step i), the blocking process is to process the edge of the upper surface of the panel by means such as adhesive tape or wood chock, so that a space (frame) in which the coating film can be formed is provided on the upper surface of the panel as shown in FIG. . The thickness of the blocking should correspond to the thickness of the desired coating film, preferably 1-10 mm. If it is less than 1mm, the thickness of the coating film is too thin, the pattern is blurred. If it exceeds 10mm, cracks may occur in the marble pattern / pattern layer.

In the treatment of the components of step ii), basically the unsaturated polyester resin and pearl are mixed and the wax is applied dropwise. Specifically, (1) after dropwise applying wax to the space on the panel, a mixture of unsaturated polyester resin and pearl is added; ② the wax is mixed with a mixture of unsaturated polyester resin and pearl and added to the space on the panel; ③ first, a mixture of unsaturated polyester resin and pearl is added to the space on the panel, and then wax is applied dropwise; Or (4) After applying some wax to the space on the panel, adding a mixture of unsaturated polyester resin and pearl, and then applying the remaining wax again.

2 to 5, the artificial marble appearance of different patterns and patterns can be formed according to the processing of ① ~ ④.

In step ii), if necessary, pigments may additionally be included in the mixture of unsaturated polyester resins and pearls depending on the color. As the pigment, a pigment as defined above may be used. In the case where the pigment is additionally included, the appearance of more various colors of artificial marble may be formed as shown in FIGS. 6 and 7.

In step iii), the coating film formed in the space on the panel in step ii) is left to stand at room temperature for 1 to 24 hours, and when completely cured, the artificial marble is completed by removing the blocking of the edge.

If necessary, prior to step i), the treatment of wiping off the upper surface of the panel with thinner once (with a cloth) results in better adhesion between the unsaturated polyester resin and the panel. Exciting usually uses polycinna for furniture.

Also, if necessary, after step iii), a surface treatment may be added for polishing by polishing the surface of the resultant artificial marble or coating with an unsaturated polyester resin. Polishing is usually paper processing. In the case of coating, coating is performed with a conventional film coating paper, or as described in the applicant's patent application No. 2005-2011, insulated unsaturated polyester resin between the artificial surrogate asbestos and the glass plate to which the release agent is applied and closely adhered to each other. Then, after the resin is cured, the glass plate may be separated to form a high gloss coating.

The finished artificial marble as described above can cut the panel edge portion that was blocked at the time of commercialization.
