Description of the Invention: [Technical Field] The present invention relates to an artificial marble and a method of manufacturing the same, and more particularly to an artificial marble using transparent chips and a method of manufacturing the same, wherein the transparent fragments are crushed by crushing The composite material is made of a flat plate which maintains transparency by not containing an inorganic filler. Further, the quartz j sheet is formed by crushing a flat plate made of a mixture of the transparent chip and the composite material, the quartz chip containing a cerium inorganic filler for uniform gravity of the artificial marble; the quartz chip is applied to the artificial Marble raw materials, so that artificial marble has a uniform specific gravity and a quartz effect. [Prior Art] Hanging, compared with natural marble, artificial marble made of acrylic resin has various advantages such as fine appearance, high processability, light weight and high strength, and thus is widely used as a counter. Materials for tables and other internal products. However, the general composition of the monochromatic opaque fragments of the artificial marble limits its performance on similar natural marble or granite patterns. "Artificial marble made of acrylic resin is prepared by mixing a filler such as aluminum chloroform, calcium carbonate or vermiculite, other pigments, and a hardener to a slurry. The slurry is obtained by mixing, for example, methacrylic acid and polymethyl methacrylate. The mixture is cast using a forming die or a continuous steel strip, and the cast product is hardened. . = Use pigments and chips to create patterns and colors of artificial marble. The debris pass g is made of the same material as the artificial marble material. However, if necessary, the chips may be made of a thermoplastic resin such as polyvinyl chloride 5 1344450 (PVC) or polystyrene (PS) or epoxy resin, unsaturated polyg. At least one pigment is added to the composite material for artificial marble, which is made into a flat plate by the same method as conventionally manufactured artificial marble, and is crushed into pieces having various sizes for manufacture. Fragments of artificial marble, which contain inorganic fillers, and whose transparency is too low, regardless of the material of the fragments. Therefore, the transparency effect it can achieve is limited. When using fragments without inorganic fillers, the _ fragments will float on the back surface of the artificial marble (the surface of the artificial marble that is not in contact with the steel strip) due to the difference in specific gravity' and will not blend with other fragments; The difference in the distribution of the fragments between the lower parts makes the artificial marble produced very susceptible to damage. Further, in the above case, when the transparent chip has the exposed rear surface of the artificial marble as the surface of the product, the artificial marble has a problem of generating pores due to gas/package and problems associated with physical properties of the surface.
韓國專利註冊第553603號揭露一種於碎片中使用 片的丙稀酸系人造大理石，此類人造大理石亦含有無機 料’因此其透明度低。 【發明内容】 [欲解決之技術問題] 本發明係因應上述問題而生，其目的係欲提供一種 造大理石，其使用了具有與f知碎片類似比重的新賴碎; ，並同時財透明度，以防止如習知碎W分離。另外 1344450 使用其表面做為產品表面以具有穩定的物理性質，並且可 展現如天然大理石般相同石英效果。本發明兼提供一種製 造該人造大理石之方法。 [解決問題之技術手段] 按照本發明之一形態，上述任一目的可藉由提供一種 包S石英碎片的人造大理石而達成，其中該石英碎片包括 用於展現石英效果之透明碎片。 該石英碎片意指能展現石英效果的碎片，該石英效果 的現象誠如天然大理石般，係指透明碎片會分散在人造大 理石表面與顯現於人造大理石内部。 本發明人造大理石之石英碎片，包括均一分散於人造 大理石基質中半透明或不透明區域的透明碎片，該石英碎 片藉由顏色差異與透光性差異而和人造大理石的基質形成 區分。 較佳地，石英碎片的比重可等於人造大理石之原料複 縊合物的比重，或和人造大理石之原料複合物的比重相差 ±0.2或更少。 本發明之人造大理石的石英碎片特徵在於’石英碎片 與人造大理石之原料複合物間的比重差達最小化，亦即人 造大理石的比重係均一的。 較佳地，石英碎片的比重可等於人造大理石之原料複 合物’當石英碎片與人造大理石之原料複合物間的比重差 低於上述數值時’碎片便不會發生分離作用。 為了製造一種像天然大理石中的石英或高純度矽石般 7 1344450 的透明度’及具倩接近於天然大理石之花紋與顏色之人造 大理石，而將透明碎片添加至人造大理石之原料複合物中 。在此’為了確保透明碎片之透明度，不加填料於如丙烯 酸系樹脂的基質樹脂中。也因為如此，當透明碎片被施用 在人造大理石時，由於透明碎片與人造大理石原料複合物 間的比重差’而導致碎片分離。 詳言之，塑性樹脂的比重為15或更小，而如聚甲基 丙烯酸甲酯（PMMA)的透明丙烯酸系樹脂，約有ιΐ7至 1.20之比重；然而，該人造大理石原料複合物之比重約^ 4鑪 至 1.8。 如上所述，透明樹脂與人造大理石之原料複合物間的 比重有差異’因此，當透明碎片由上述樹脂構成且被施用 於人造大理石時’透明碎片即會產生分離。由於且有高比 重（大於i綱透明聚合物目前不存在，所以沒有使用透明 碎片的人造大理石。 根據本發明，藉由均勻化比重而使石英碎片與原料複 二物間的比重差至最小，藉此使透明碎片可呈現如天然石J 英般相同的效果而不會發生碎片分離現象。 石英碎片的總比重較佳為14至18，以接近於人造大

that its transparency is low. SUMMARY OF THE INVENTION [Technical Problem to be Solved] The present invention has been made in view of the above problems, and its object is to provide a marble which uses a new smash with a similar gravity to the shards; In order to prevent the separation of W as is known. In addition, 1344450 uses its surface as a product surface to have stable physical properties and can exhibit the same quartz effect as natural marble. The present invention also provides a method of making the artificial marble. [Technical means for solving the problem] According to one aspect of the invention, any of the above objects can be attained by providing an artificial marble containing S-streak fragments, wherein the quartz chips include transparent chips for exhibiting a quartz effect. The quartz chip means a piece that exhibits a quartz effect. The phenomenon of the quartz effect is like natural marble, meaning that the transparent pieces are scattered on the surface of the artificial marble and appear inside the artificial marble. The quartz flakes of the artificial marble of the present invention comprise transparent flakes uniformly dispersed in a translucent or opaque region of the artificial marble matrix, the quartz flakes being distinguished from the matrix of the artificial marble by a difference in color and light transmission. Preferably, the specific gravity of the quartz chips may be equal to the specific gravity of the raw material composite of the artificial marble or the difference of the specific gravity of the raw material composite of the artificial marble by ± 0.2 or less. The quartz flakes of the artificial marble of the present invention are characterized in that the difference in specific gravity between the composite material of the quartz flakes and the artificial marble is minimized, that is, the specific gravity of the artificial marble is uniform. Preferably, the specific gravity of the quartz chips may be equal to the raw material composition of the artificial marble. When the difference in specific gravity between the composite material of the quartz chips and the artificial marble is lower than the above value, the fragments do not separate. In order to create a kind of artificial marble like quartz or high-purity vermiculite in natural marble, and the artificial marble with a pattern and color close to that of natural marble, transparent pieces are added to the raw material composite of artificial marble. Here, in order to ensure the transparency of the transparent chips, no filler is added to the matrix resin such as an acrylic resin. Also, when the transparent chips are applied to the artificial marble, the fragments are separated due to the difference in specific gravity between the transparent chips and the artificial marble raw material composite. In detail, the specific gravity of the plastic resin is 15 or less, and the transparent acrylic resin such as polymethyl methacrylate (PMMA) has a specific gravity of about 7 to 1.20; however, the specific gravity of the artificial marble raw material composite is about ^ 4 furnaces to 1.8. As described above, there is a difference in specific gravity between the raw material composite of the transparent resin and the artificial marble. Therefore, when the transparent chips are composed of the above resin and applied to the artificial marble, the transparent fragments are separated. Since there is a high specific gravity (more than the i-type transparent polymer is not present at present, there is no artificial marble using transparent fragments. According to the present invention, the difference in specific gravity between the quartz fragments and the raw material complex is minimized by homogenizing the specific gravity, Thereby, the transparent fragments can exhibit the same effect as the natural stone J without the separation of the fragments. The total specific gravity of the quartz fragments is preferably 14 to 18, which is close to the specific gravity of the artificial marble raw material composite, and more preferably It is 15 to 17. The transparent chips of the artificial marble of the present invention have a light transmittance of 9 to 1%, and preferably more than 95%. Conventional chips contain a filler such as aluminum hydroxide, so It is translucent and has a light transmittance of less than 60%. The matrix resin used for the transparent chips of the artificial marble of the present invention is a translucent 8 =::: resin such as an acrylic resin (pm MA), a polyester resin, and (PET). Preferably, the transparent shard is an acrylic slab which is transparent to a bisenoic acid resin which is used as a kebab tree. The acid smash = marble: the transparent propylene used directly has a specific gravity of 9 Two light transmission Excellent physical properties such as town i = now the same effect as natural quartz; and 'there can be applied or polished post-treatment, these are implemented by the law. Dingmen mouth is more than a smashing of quartz. The raw material of the translucent or opaque matrix area is compounded with two y to adjust the specific gravity of the transparent granules. * The use of oxidizing chin, sulphur, smelting, carbon, shoal, metal powder and metal salts is used as a filler for 4 fields. The filler has a specific gravity of at least 2.5, preferably 2.5 to 1 〇, and has a specific gravity-adjusting effect per reinforced amount of the filler used, and the filler preferably has a high specific gravity. The artificial marble of the present invention per 100 parts by weight The artificial marble I raw material composite contains 2 to 40 parts by weight of quartz chips. The artificial marble original, the composite contains: i (10) parts by weight of the base f resin slurry, 50 to 250 weights of inorganic filler, 〇 1 to 1 〇 by weight of the crosslinking agent and 〇1 to 10 parts by weight of the polymerization initiator. The inorganic filler in the raw material composite of the jinjin artificial marble is preferably selected from the group consisting of gas oxidation, magnesium hydroxide, and sulphuric acid. Carbon dance , one or a mixture of two or more of the group of dream stone and oxidized, and most preferably a gas alumina. The inorganic filler is used in an amount of 50 to 250 parts by weight, preferably up to 200 stars. When the content of the inorganic filler is lower than the lower limit, the viscosity of the raw material complex 9 1344450 is too low, and the strength and surface hardness of the flat plate prepared by the hardened raw material composite are also decreased; when the content of the inorganic filler is higher than the upper limit ^ The viscosity of the raw material composite is high and the handling is difficult. The weight of the flat plate is increased, but the impact strength of the flat plate is lowered, and the floating of the quartz = sheet = flat plate is also increased. The composite material of the preferred artificial marble is composited. The viscosity of the material ranges from 3 丨 to 8 (Poise). However, the viscosity of the raw material composite can be obtained by using acrylic tree scorpions, especially low-viscosity monomers and additives, and by inorganic substances and strontium fragments. Adjustments are not restricted. The amount of quartz chips used can vary depending on the size of the quartz chips! · 隹, preferably 2 to 40 parts by weight. When the content of the quartz chips used is not higher than the lower limit, the probability that the quartz pieces are present on the surface of the artificial marble is low, so the artificial marble does not exhibit a quartz effect. On the other hand, when the content of the quartz chips used is higher than the upper limit, the viscosity of the raw material composite may be increased to cause breakage of the artificial marble and increase the generation of bubbles. The matrix resin used in the raw material composite of the artificial marble of the present invention is composed of = plastic resin (such as vinyl (PS) or polystyrene (ps)) or thermosetting 4 W (such as epoxy resin or unsaturated polyester). It is preferably composed of an acid resin. The quartz pieces of the artificial marble of the present invention contain 5G to · parts by weight of transparent fragments per 1 part by weight of the artificial stone. The composite material comprises: 1 (10) parts by weight of a matrix resin slurry, _ to 5 ounces by weight of the inorganic filler, to 1 gram by weight of the crosslinking agent, and 0.1 to 10 parts by weight of the polymerization initiator ' & 0.5 to 3 parts by weight of a thixotropic reagent made of fine vermiculite 10 13444^0. Preferably, the inorganic filler of the composite material of the enamel core is selected from the group consisting of oxygen oxol, hydrogen oxy-μ, talc and carbonate, or a mixture of two or more, and most preferably hydrogenated. Preferably, the filler of 1:2 is contained in 300 parts by weight of the matrix resin slurry. When the content of the inorganic filler is lower than the lower limit, the image of the composite material and A' float on the surface of the artificial marble, and when the inorganic filler contains aging, it is difficult to handle. Transparency = 1ΐ:::. Complex: The viscosity of the material becomes higher than the layer separation in the plate, and it will reduce the impact strength of the plate. In order to prevent the floating and separation of the transparent fragments, the proportion of the film is best. It is from 1.4 to 1.8, and more preferably from 15 to 1. In this case, the amount of inorganic substances should be increased to the maximum. In the present invention, the wide separation of transparent fragments in the plate for producing quartz chips becomes very large = To solve this problem, a composite material towel is used to reduce the transparent debris = a thixotropic agent' and the plate has a thickness equal to the transparent chip size • large diameter, thereby greatly preventing layer separation. The penetration diameter does not exceed ό cm.兮补: The transparent pieces of artificial marble consist of a composite material containing: 100 parts by weight of a matrix resin slurry, (U to 10 ^ X-linking agent' and Q1 to 1 part by weight of a polymerization initiator The stone piece may be made of a conventional acrylic plate capable of maintaining transparency. According to another aspect of the present invention, there is provided a method for manufacturing artificial marble 11 1344450 ^ Method 'includes: by using an artificial marble The composite material forms a flat plate, and the flat plate is hardened and the hardened flat plate is crushed to produce a transparent piece containing no inorganic filler; the transparent plate is mixed with the composite material for artificial Dali to form another flat plate and hardened. The other plate and the other plate that is hardened to produce a quartz filler containing an inorganic filler; and mixing the raw material composite of the quartz chip with the artificial marble. Preferably, the inorganic filler is adjusted by adjusting the quartz chip. The specific gravity and content of the quartz shards become equal to or close to the specific gravity of the composite material of the artificial marble. Moreover, in order to prevent the floating and separation of the transparent shards, the slab used in the method of preparing the granules has the largest equivalent of the transparent shards. The thickness of the diameter is 0. [Embodiment] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. The method of producing artificial marble according to the present invention will be described in detail below. The method of the present invention comprises: manufacturing transparent shards , making quartz chips, and making the artificial marble. First, using an artificial A composite material for marble to produce a flat-shaped hardened product containing no inorganic filler, and crushing the product into transparent pieces. The transparent piece is composed of a composite material for artificial marble, the composite material containing: 100 parts by weight For example, a matrix resin slurry of an acrylic resin, 0.1 to 10 parts by weight of a crosslinking agent', and 0.1 to 10 parts by weight of a polymerization initiator 12 1344450. An acrylic resin, an unsaturated polyester resin, an epoxy resin, Polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), polyethylene terephthalate (PET), or styrene-methyl methacrylate (SMMA) copolymer resin as matrix Resin. The matrix resin slurry is composed of a resin monomer and/or a resin polymer. Usually, the matrix resin slurry is composed of a mixture of a monomer and a polymer. Preferably, a polymerizable acrylic monomer is used as the matrix resin. More specifically, the acrylic resin slurry is composed of a methacrylic acid monomer or a monomer selected from the group consisting of methacrylic acid vinegar (MMA), methyl propyl phthalate (EMA), butyl methacrylate (BMA), 2 A mixture of two or more kinds of methacrylic acid monomers of a group of -ethylhexylmercaptoacrylate (EHMA), benzyl mercaptopropionate, and glycidyl methacrylate (GMA). Further, the acrylic acid resin slurry is composed of a mixture of a methacrylic acid monomer and a part of its polymer. Preferably, the acrylic resin slurry is composed of a mixture of MMA and poly MMA, and preferably, The polymer content in the acrylic resin slurry is from 1 〇 to 5 〇 by weight. The crosslinking agent for the composite material for artificial marble of the present invention is a polyfunctional acrylic monomer or is selected from the group consisting of ethylene glycol dimethacrylate (EDMA) and diethylene glycol dimercapto acrylate (2EDMA). Triethylene glycol dimercaptopropionic acid S曰 (3EDMA), tetraethylene glycol dimethacrylate (4ε〇μα), trimethylolpropane tridecyl acrylate (TMPMA), 1,6-hex a mixture of two or more monomers of diol dimethacrylate, polybutylene glycol dimethacrylate and neopentyl glycol dimercapto acrylate, preferably 13 1344450 crosslinker It consists of EDMA. The polyfunctional acrylic monomer used in the intramolecular copolymerization reaction includes a double bond, thus forming a crosslinking agent containing a polyacetic acid resin. When no crosslinking agent is used or a low amount of crosslinking agent is used, the bonding ability in the raw material of the artificial marble is lowered, so that an artificial marble having an irregular surface is formed, and bubbles are formed in the upper and lower portions of the artificial marble; The heat resistance and discoloration of artificial marble also deteriorate. On the other hand, when an excessively high content of the crosslinking agent is used, phase separation of the chips occurs, and thus many problems associated with artificial marble patterns are generated. Accordingly, the preferred amount of crosslinking agent in the furnace is from 〇丨 to (7) parts by weight per part by weight of the resin slurry. The polymerization initiator of the composite material for artificial marble of the present invention is used for polymerizing and hardening a resin slurry, which is selected from the group consisting of organic peroxides (including bismuth peroxides such as peroxides and Diisopropyl peroxide) Hydroperoxide (such as hydroperoxide, cumene hydroperoxide, second-butylperoxybutenedioic acid, hydrogen peroxide third-butyl, third Butyl hydroperoxy butyl I), peroxide, copper peroxide, azobis > = nitrile, azo | dimethyl valeronitrile, tributyl butyl peroxy neodecanoate One or two or a mixture of more than one species of the group of the third-pentylperoxy-2-ethylhexanoate. Further, the resin slurry can be polymerized and hardened by using a mixture of peroxide and sulfuric acid or a mixture of a peroxide and a guar compound at room temperature. = Ground, the polymerization initiator used was 9 parts by weight to ig parts by weight per 10 parts by weight of the tree. Typically, the polymerization initiator is used with a polymerization 14 reaction accelerator. When the content of the polymerization initiator used is too low, the rate of hardening of the composite for artificial marble becomes slow, and the composite for artificial marble cannot be sufficiently hardened. On the other hand, when the content of the polymerization initiator used is too large, the hardening effect of the composite for artificial marble may be delayed' and the composite part for the artificial marble may not be hardened. Further, a chain carrier (group carrier) can be used as the molecular weight adjustment, and the group carrier is a thiol compound selected from the group consisting of n-dodecyl mercaptan, second I-nonyl mercaptan, and noon. a group of alcohols and tridecyl thiols. Preferably, the group carrier is contained in an amount of 0.1 to 5 parts by weight per 100 parts by weight of the resin slurry. When the content of the group carrier is too low, the effect of the group carrier cannot be achieved; and when the content of the group carrier is too high, the hardening rate of the composite material for artificial marble is significantly reduced, thereby making the composite material for the artificial marble Can't completely harden. The composite material for artificial marble may additionally contain at least one additive I' selected from the group consisting of an anti-foaming agent made of a ruthenium or a non-ruthenium compound, and a chopped fire containing a dimethyl emulsion-based calcination as a main component. A coupling agent, an acid, or a titanic acid, an organic or inorganic pigment or dye, an ultraviolet absorber composed of phenyl salicylate, a benzophenone, a benzotriazine, a street creature, or a radical scavenger, and a halogen a fire retardant, phosphorescent or inorganic metal, a release agent composed of stearic acid or hydrazine, a polymerization inhibitor composed of catechol or hydroquinone, a thixotropic agent made of fine vermiculite, and A group of antioxidants consisting of phenol, amine, quinine, sulfur or hydrazine. The above composite material for artificial marble is supplied by a batch feeder and dispersed by an impeller of 15 1344450, and the mixed raw material slurry is discharged and supplied onto the steel strip to a set thickness, thereby casting It is used to manufacture a flat plate for transparent chips and hardens the plate. Preferably, the flat plate is formed by continuous casting, i.e., the raw material slurry system discharged from the outlet nozzle of the batch feeder is supplied to the movable steel strip to be moved and hardened by the drive steel. The hardened plate is placed in a crusher, and then the plate is crushed into transparent pieces having a set size using a crusher, and a conventional mill (hammer or crusher) for crushing stones is used. The mill) is used as a crusher, preferably, it is transparent. The shards have a particle size of 2 to 6 mm. When the size of the transparent fragments is larger than 6 faces, the layer separation caused by the floating of the transparent fragments becomes severe, and the surface of the product is clearly formed as a composite layer due to the non-uniformity of the specific gravity of the quartz fragments. Since the transparent chips produced have various sizes and are appropriately mixed according to the size when producing quartz chips; therefore, when only a small-sized transparent chip is used, the thickness of the cast plate is changed due to the serious floating of the transparent fragments. Small and (iv) yield reduction; and 'when only transparent fragments having a large size are used, j is because the spacing between the transparent fragments is increased, so that the quartz fragments do not contain any transparent portions or only transparent portions. Subsequently, the transparent chips were mixed with the inorganic filler-containing composite material for artificial marble, the mixture was cast into a flat plate, and the plate was hardened, and the plate was crushed into quartz pieces containing transparent chips. The quartz chip is composed of a mixture of 50 to 200 parts by weight of transparent chips and 1 part by weight of composite material for artificial marble, the composite material = 16 ^ 44450 3 having .100 parts by weight of the matrix resin slurry to 500 The weighting agent m1 〇 parts by weight of the crosslinking agent, 〇.lil0 parts by weight of the polymerization; = the starting agent, and 0.5 to 3 parts by weight of the thixotropic reagent. The inorganic filler of the composite material for artificial marble is an inorganic powder which is one or two or two selected from the group consisting of hydrogen hydroxide, oxyhydroxide, sulphuric acid horn, carbonic acid dance, shishi stone' and alumina. Preferably, the mixture of the above mixture has an inorganic filler having a particle size of 5 to 2 Å, and the particle size of the material is too small, and the light transmittance of the artificial marble is lowered; and when the particle size of #无和=料 is too large, The physical properties of artificial marble will deteriorate. Preferably, in order to improve the dispersibility with the tree and the mechanical strength of the product and to prevent the precipitation of the solid matter, the surface of the plate is treated by a coupling agent or stearic acid prepared by the purpose of the stone or the bismuth acid. . Further, the "preferred" inorganic filler is present in parts to parts by weight per 100 parts by weight of the matrix resin slurry. The method of producing the quartz chips is the same as the above method of manufacturing the transparent chips. Preferably, the quartz is crushed; the size of J Μ P + is 0.1 to 1 〇. When the quartz fragments are in the Η)·, the oversized quartz is broken, which is why the product of the marble is a flat plate having a thickness of about 14 mm, and the large piece of the piece causes the artificial marble portion between the chip and the base f. It is not possible to apply to the excessively large size of quartz fragments in the impeller of the mash-based batch feeder. The size of the quartz fragments is ten 扪L, and the use of the central debris is more favorable due to the smaller size of the quartz fragments. “The large quartz fragments are more conducive to the pattern of the 17 1344450 artificial marble product. Therefore, it is preferable to make the quartz pieces into various sizes, which are appropriately mixed according to the size when producing artificial marble.
