You can also implement

The specific kind of resin which comprises the above-mentioned resin part 2 will not be specifically limited if the light transmittance after hardening exists in the said range. For example, in the present invention, one or more selected from the group consisting of acrylic resins, unsaturated polyester resins, and epoxy resins can be used, and the specific types thereof are as described above.

The resin part 2 of the present invention may also contain a transparent pigment or a transparent dye, etc., in addition to the above-mentioned transparency or translucent resin. Due to the inclusion of such pigments or dyes, the resin part 2 itself has a unique color, thereby realizing a variety of decorative effects in the case of no lighting effect or the like by day or the like. Specific examples of the transparent pigment or dye that can be used in the present invention are not particularly limited, and various dyes or pigments known in the art may be used. The content of such a transparent pigment or dye is not particularly limited, and may be appropriately selected within a range that does not impair transparency or translucency of the resin portion 2.

In the present invention, the resin constituting the resin part 2 may also include various additives included in the base resin part 1 described above. However, in the case of a specific additive such as an inorganic filler, since it may adversely affect the transparency when included in the resin part 2, it is preferable to use an additive whose refractive index is adjusted so as to minimize the content or not impair the transparency.

The content in the base resin 1 of the resin portion 2 is not particularly limited and may be appropriately selected according to the desired effect.

The method for producing the artificial marble of the present invention is not particularly limited, and conventional methods in this field can be applied without limitation. For example, in order to manufacture a artificial marble having a linear pattern, after preparing a slurry for the transparent resin portion, the slurry is administered by means such as a nozzle so as to form a linear pattern in the base resin to prepare a composition, The method of hardening and manufacturing this is mentioned. In the case of the dot pattern may be prepared by appropriately mixing the slurry for the transparent resin portion and the base resin, and curing the obtained composition through a press method. In addition, those skilled in the art can easily select and apply an appropriate manufacturing method according to the shape of the desired pattern.

The artificial marble of the present invention includes a base resin portion 1 and a transparent or semi-transparent resin portion 2 as described above, and during the daytime, the transparent or semi-transparent resin portion 2 produces a unique decoration itself. At night, various decorative effects can be produced by allowing the light by the light installed on the inside or the back to leak out through the transparent or translucent resin part 2 penetrating the artificial marble. As the decoration effect can be produced regardless of day / night, the artificial marble of the present invention can be used as a partition of a restaurant, a counter top of a bank or a general store, interior / exterior decoration materials of various buildings, wall panels and flooring materials, etc. It shows an excellent effect compared to the existing, it can be used as direct lighting by adjusting the illuminance of the light installed on the inside or the back or the transparency of the pattern portion.
