The present invention relates to a composition for artificial marble, and more particularly, the present invention relates to a composition for artificial acrylic marble having a novel pattern formed by the use of particles of a polyester film with deposited metal to maximize the diffuse reflection of artificial marble. BACKGROUND OF THE INVENTION Artificial marble has been widely used as a construction material and is classified into two groups according to its base resin material: the first comprises artificial acrylic marble and the second comprises unsaturated polyester artificial marble. Recently, artificial acrylic marble has been widely used due to its excellent appearance, high class texture and good weather resistance compared to unsaturated polyester artificial marble. For example, artificial marble is used as material for kitchen countertops, sinks, toilets, bathtubs, table tops, wall materials, interior items, etc. Conventional artificial marble has been used to produce products with rock-like textures. However, it is necessary to develop artificial marble that has different patterns and designs so that: the use and application of artificial marble can be expanded and diversified. Applicants of the present invention developed a composition for artificial marble having a metallic luster thanks to the addition of aluminum powder thereto (Korean Patent Application No. 2004-103499). Although it was successful in providing a metallic appearance and feel to artificial marble, it had limits in terms of the creation of more varied sophisticated patterns. In particular, there is an urgent need to develop advanced products as consumers prefer more luxurious and sophisticated products.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a photograph showing a surface pattern of artificial marble which contains particles of a polyester film with deposited metal. Fig. 2 is a photograph showing a surface pattern of an artificial marble product obtained in the Comparative Example. Detailed description of the invention. The composition for an artificial acrylic marble according to the present invention comprises a) an acrylic resin polymer, b) a particle layer of a polyester film with deposited metal, and c) an inorganic filler. The detailed description of the present invention is as follows, a) Acrylic resin polymer The acrylic resin polymer that can be used in the present invention is a mixture of an acrylic monomer and its polymer, polyacrylate, dissolved therein. Typical examples of an acrylic monomer include methacrylic acid, methyl methacrylate, ethyl methacrylate, isopropyl methacrylate, n-butyl methacrylate, and 2-ethylhexyl methacrylate and so on.
The polyacrylate can be a homopolymer or a copolymer of methyl methacrylate, ethyl methacrylate, isopropyl methacrylate, n-butyl methacrylate, 2-ethylhexyl methacrylate or the like. Among said compounds, polymethylmethacrylate (PMMA) may be preferred. In one embodiment, the acrylic monomer is equal to or greater than 65% by weight and the polyacrylate is equal to or less than 35% by weight based on the total amount of acrylic resin polymer. b) Particles of polyester film with deposited metal. The particles of polyester film with deposited metal are used to provide a novel pattern for an artificial marble. The content of polyester film particles with deposited metal is in the range of 0.1 to 5 parts by weight per 100 parts by weight of an acrylic resin polymer. Generally, resplendent conventional particles are produced by coating and printing a polyester film with a colorant to subsequently cut the coated or printed film. However, when these coated or printed glowing particles are used in artificial marble, they do not reflect light correctly, so that the reflective effect is insufficient. In the present invention, the polyester film is deposited in a plurality of metal layers to maximize diffuse reflection, such that the resplendent effect can be increased. The deposited metal polyester film particles of the present invention are produced by depositing a plurality of metal layers on the surface of the polyester film and cutting or spraying the polyester film with metal deposited on pieces or particles with a size between about 0.001 to 2.5 mm. The thickness of the polyester film can be between 30 to 100 μm. If the thickness is less than 30 μm, deformation may occur. If the thickness was greater than 100 units, flexibility could decrease.
The polyester film is preferably deposited, in multiple layers of metal, rather than in a single layer. Accordingly, the resplendent effect can be increased due to a discontinuity between layers. In order to increase the discontinuity, the direction of the deposit or the angle of the deposit between the layers can be varied. The number of deposited metal layers is not particularly limited, but the total thickness of the metal deposit in the particles of the polyester film can be preferably 10 μm and more particularly between about 1 to 3 μm. The polyester film with deposited metal is cut or pulverized into pieces or particles with a size of approximately between 0.001 to 2.5 mm to provide a novel pattern and more preferably between 0.004 to 2.5 mm. Cut or spray particles of a single size or of various sizes can be used. If the particle size is greater than 2.5 mm, it may not have a pattern as attractive as expected and if the size is less than 0.001 mm, the reflective effect may be insufficient. In the present invention, a more splendid appearance and a novel pattern can be produced by using particles of a polyester film with deposited metal, and the diffuse reflection can be maximized by glowing particles which make the particles appear larger in size. what they really are. The content of the deposited metal polyester film particles is in the range of from about 0.1 to 5 parts by weight per 100 parts by weight of an acrylic resin polymer. If the content is greater than 5 parts by weight, it may be difficult to provide the desired appearance due to inefficient diffusion, and if the content is less than 0.1 parts by weight, the reflection may be insufficient. In some embodiments, conventional artificial marble particles may be optionally added, having sizes between about 0.1 mm to 5 mm to provide artificial marbles with various patterns.
The marble particles can be prepared by a conventional method. For example, marble particles can be prepared by mixing 100 parts by weight of an acrylic resin polymer, between 120 to 200 parts by weight of an inorganic filler, between 0.1 to 10 parts by weight of a linker and between 0.1 to 10 parts by weight. parts by weight of an initiator, curing the mixture and pulverizing the cured material into particles with a size between 0.1 to 5 mm. The marble particles can be added to an amount of 100 parts by weight per 100 parts by weight of an acrylic resin polymer. c) Inorganic filler Any inorganic material that is well known in the art as filler can be used as an inorganic filler. Typical examples of inorganic fillers include calcium, carbonate, aluminum hydroxide, silica, alumina, barium sulfate, magnesium hydroxide, etc. Preferably, the inorganic filler to be used in the present invention can have a particle size of between 1 to 100 μm. Among the aforementioned materials, aluminum hydroxide is the preferred material in view of its transparent and elegant appearance of artificial marble that can be obtained. The content of inorganic filler can be in the range of 100 to
200 parts by weight, preferably between 120 to 160 parts by weight per 100 parts by weight of acrylic resin polymer. If less than 100 parts by weight are added, the viscosity of the slurry increases, so that the strength and hardness of the artificial marble obtained in this way may deteriorate. On the other hand, if the content is greater than 200 parts by weight, its malleability can be reduced. d) Polymerization initiator. Examples of polymerization initiators include peroxides such as benzoyl peroxide, lauroyl peroxide, butyl hydroperoxide, cumyl hydroperoxide, etc., and also components such as azobisisobutyronitrile and the like.
The content of the polymerization initiator can be in a range of from about 0.1 to 10 parts by weight, per 100 parts by weight of an acrylic resin polymer. The artificial marble of the present invention can be prepared by a conventional method. For example, all the components and additives are mixed to obtain an artificial marble grout. Then the slurry is deposited in a molding container and finally cured to form an artificial marble product. The invention can be better understood with reference to the following examples which are intended to illustrate the invention and not to limit the scope of the present invention, which is defined in the appended claims. Example. 100 parts by weight of a methyl-methacrylate resin syrup consisting of a mixture of 30% polymethyl methacrylate and 70% methylmethacrylate, 0.7 parts by weight of polyester film particles with deposited metal having a particle size of about 0.2 mm (Hologram Silver JW1401 produced by Changwon Industrial Co.) and 1 part by weight of polyester film particles with deposited metal having a particle size of about O.dmm (Hologram Silver JW1401 produced by Changwon Industrial Co.), 120 parts by weight of aluminum hydroxide, and 2 parts by weight of lauroyl peroxide were mixed to obtain a slurry for artificial marble. The slurry was placed in a molding and curing vessel to obtain an article with a solid surface in the form of a flat sheet. The resulting article is shown in the photograph of Figure 1.
