200825034 九、發明說明： 【發明所屬之技術領域】 本發明係關於人造大理石及其製法，尤其關於運用共 押出將具有高比重的樹脂層塗佈在内部透明樹脂層外表 面，以獲得内含球狀透明薄片之人造大理石及其製法。义 【先前技術】 一般而言，相較於天然大理石，由壓克力樹脂製成的 广人造大理石具有許多優點，如細緻的外觀、好加工、輕量 ，高強度，因此已廣泛用來當成櫃檯桌面以及其他屋内 產品的材料。不過，一般由單色不透明薄片組成的人造大 理石，其在呈現近似於天然大理石或花崗石花紋的能力卻 有所限制。 壓克力樹脂製成的人造大理石，是混合氫氧化鋁、碳 酸鈣或氧化矽、染料及硬化劑這類的填充物，以形成一泥 狀混合物。然後再混合甲基丙烯酸甲酯這類單體和聚甲^ (丙烯酸甲酯，並以成型模具或連續模具鑄模並硬化而成。 為了形成人造大理石的花紋與顏色，通常會使用染料 與薄片。薄片通常由和人造大理石相同的樹脂所製成，並 且染料與填充劑都會投入樹脂中，如此在薄片應用時，其 會與人造大理石用的原料具有相同的比重。薄片是藉由斑 人造大理石相同的製程來生產，而經打碎的薄片具有許多、 顏色以及顆粒般大小。 ~ ° 特別的是，當製造出内含上述薄片的人造大理石時， 必須將人造大理石與薄片間的比重差異所導致的層離^況 5 200825034 最低為此，使用如煤或氫氧化鋁這類的無機填充物 來調整薄片比重，並在薄片的比重等於人造大理石基材的 比重之後，於薄片用的樹脂中投入許多染料，然後形成板 狀再碎裂成薄片。當薄片由壓克力樹脂製成時，由於填充 ，加入薄片原料中造成薄片變成不透明，而無法仿出天然 花崗石或大理石的晶紋。 再者，當以單一成份無添加填充物的透明聚合物所製 造之透明薄片加進人造大理石時，由於構成人造大理石的 f轉片與原料之間的比重差異會導致薄片層離，所以大理石 内的薄片尺寸與供應量都受到限制。因此，上述透明薄片 無法仿效天然大理石的晶紋。 私國專利申請案第491874號揭露一種人造大理石，其 内^ · (A)l〇〇等份重量的人造大理石％，其内含觸等份 重量的壓克力樹脂泥糊、120〜2〇〇等份重量的無機填充物 、H0等份重量的交鏈劑和g.hg#份重量的聚合啟動劑 ^以及（B)5〜70等份重量的大理石f片，其时1〇〇等份重 量的壓克力樹脂泥糊、1GG〜15G等份重量的無機填充物、 H0等份重量的交鏈劑和g.hg等份重量的聚合啟動劑 ，其中人造大理石泥内無機填充物的混合比例高出大理石 薄片的混合比例20〜50等份重量。上述專利中揭露採添加 無機填充物到壓克力樹脂而獲得的大理石薄片因為不透明 ，所以無法仿效天然大理石或花崗石内的晶紋。 因此，為了克服上述傳統人造大理石的技術限制，本 發明人發明了一種内含透明薄片的人造大理石，其是以共 200825034 押出塗佈如壓克力樹脂或PET等具有高比重樹脂層的透明 聚合樹脂，再切割該押出體而製成。如此，透明薄片具有 近似於人造大理石原料的比重，而得以呈現近似於天然大 理石内的石英或高純度氧化矽的透徹度；如此，相較於由 不，明薄片或半透明單一成份所製作的傳統人造大理石， 更能呈現近似於天然大理石的花紋。 【發明内容】 [欲解決之技術問題] 〇士鐘於上述問題，本發明的目的在提供一種應用於人造 :石的透明薄片’每一薄片皆以高比重樹脂層塗佈在内 用以』ίί層的外表面上，該高比重樹脂層内含填充物， 此、^'的總比重調整成與人造大理石原料的比重，藉 此泊除發生層離的現象。 猎 人造-種應用上述透明薄片的 f不透明薄片的1造大理=紋和顏色方面與傳統内含 里石。 绝大理石有明顯區別，且更近似於天然大 [解決問題之技術手段] 根據本發明的—眚 _ 人造大理石 ，樣’猎由製備内含透明薄片的 都包含内部透明層有㈣。其中每-人造大理石 ，並形成於㈣料層料高於㈣翻層的比重 車父佳的是’透明薄 或與人造大理石原料相差 樣 的人造大理石之原料一接體=重可與使用了透明薄片 7 200825034 ±0.2g/cm3 或更少。 本發明的人造大理石之特徵在於，透明薄片與人造大 理石原料間之比重差異降至最低；較佳的是，透明薄片的 比重等於原料的比重。當透明薄片與人造大理石原料間之 比重差異在上述範圍内，則薄片分離的現象就不會發生。 為了製造可呈現近似於天然大理石中石英或高純度氧 化=的透徹度之人造大理石，以及具有近似於天然大理石 之花紋與顏色，於是在人造大理石原料中加入透明薄片。 Γ為了確認透明薄片的透明度，填充物並不會加人諸如壓克 力樹脂的基底樹脂内。因此’當透明薄片應用至人造大理 石，由於比重的差異會發生薄片分離現象。 -尤/、疋’塑膠樹脂的比重為15g/cm3或以下，並且透 ^ C克力树月日’例如聚甲基丙烯酸甲酯（pMMA)的比重大約 ，不過，人造大理石原料的比重則大約 疋 1·4〜1.8g/cm3。 如上豸i^明樹脂與人造大理石原料間之比重有所差 :田透明薄片由上述樹脂製成並應用至人造大理石，則 二=明薄片分離現象。這是因為目前並不存在具有較 L=6g/cm3)的透明聚合物，所以並無人造大理石 外# ^ *透明薄片的表面上形成具有高比重的 明二片料之間的比重差異降至最低，如此允許透 情況。 ，、天然石英相同的效果，而不發生薄片分離 8 200825034 較佳的是，透明薄片的整體比重為13〜2〇g/cm3，近 似於人造大理石原料的比重。再者，較佳的是外層的比重 為1.5〜10g/cm3,如此透明薄片的整體比重在上述範圍内。 内部透明層具有90〜100%的透光率，較佳的是超過 95%。傳統薄片内含如氫氧化鋁的填充物，因此為半透明 並且具有低於60%的透光率。 用於内部透明層和外層的基底樹脂為透明聚合樹脂， 如壓克力樹脂（PMMA)、聚酯樹脂以及聚對苯二甲酸乙二酯 ΓΙΡΕΤ)。較佳的是，透明薄片為使用壓克力樹脂當成基底樹 脂的透明壓克力薄片。 ^根據本發明，具有高比重外層的透明壓克力薄片具有 高透光率以及優異的物理特性，呈現出與天然石英薄片相 同的效果，並且適用於後置處理，如鑄造或拋光。 外層包含填充物，用於調整透明薄片的比重，並且二 氧化鈦、硫酸鋇、氫氧化鋁、碳酸鈣、氧化矽、金屬粉末 及金屬鹽都可用來當成合適的填充物。填充物的比重至 少為2.5g/cm3，較佳在2 5〜1〇g/cm3的範圍内。為了增加所 使用的每份重量填充物比重之調整效果，填充物要具有高 比重。 在其間可形成如黏貼層或底漆層這類用於改善内部透 明層與外層之間黏貼性的第三層。 内部透明層可包含珍珠染料。然後，透明薄片從内部 以及表面上呈現出珍珠效果，如此比只在表面上呈現珍珠 效果的傳統薄片，呈現出更令人印象深刻的珍珠效果。 200825034 透明薄片的形狀並不設限。例 形或多面形’如四面以及六面形：明，片具有圓柱 薄片時，透明薄片具有圓柱形或六面田^、押出來製造透明 外層全部或部分形成於内部透明声 共押出製造透明薄片時，外層 二、面上。虽採 外的整個外表面上。 、押出物的切割平面以 透明大理石的外觀效果與可塑性，較佳的是 购:=°_的尺寸，並且供應量為人造大理石 理石發明的其他實施態樣，其提供-種製備人造大 比重包::r部透明層外表面上形成比重高於 德蔣nl ^的外層’並切割和壓碎所獲得的產品，然 後將透㈣片加進人造大理石的原料中。 =薄片的比重可採調整加入於外層的填充物之比重200825034 IX. Description of the Invention: [Technical Field] The present invention relates to artificial marble and a method for producing the same, and more particularly to applying a resin layer having a high specific gravity to an outer surface of an inner transparent resin layer by co-extrusion to obtain an inner ball Artificial marble of transparent sheet and its preparation method. [Prior Art] In general, wide artificial marble made of acrylic resin has many advantages compared with natural marble, such as fine appearance, good processing, light weight, high strength, so it has been widely used as a Counter desktops and materials for other in-house products. However, artificial marbles, which are generally composed of monochromatic opaque sheets, have limitations in their ability to exhibit a pattern similar to natural marble or granite. The artificial marble made of acrylic resin is a filler such as mixed aluminum hydroxide, calcium carbonate or cerium oxide, a dye and a hardener to form a muddy mixture. Then, a monomer such as methyl methacrylate and polymethyl methacrylate (methyl acrylate) are mixed and molded by a molding die or a continuous die and hardened. In order to form the pattern and color of the artificial marble, dyes and flakes are usually used. The flakes are usually made of the same resin as the artificial marble, and both the dye and the filler are put into the resin, so that when the flake is applied, it will have the same specific gravity as the raw material for the artificial marble. The flakes are the same as the artificial marble The process is produced, and the broken sheets have many, color and particle sizes. ~ ° In particular, when the artificial marble containing the above-mentioned sheets is produced, the difference in specific gravity between the artificial marble and the sheets must be caused. The delamination condition 5 200825034 The minimum is to use an inorganic filler such as coal or aluminum hydroxide to adjust the specific gravity of the sheet, and after the specific gravity of the sheet is equal to the specific gravity of the artificial marble substrate, it is put into the resin for the sheet. Many dyes are then formed into a sheet and then broken into flakes. When the sheet is made of acrylic resin, due to filling The addition of the flake material causes the flakes to become opaque, and does not mimic the grain of natural granite or marble. Furthermore, when a transparent flake made of a transparent polymer having a single component without a filler is added to the artificial marble, Since the difference in specific gravity between the f-rotating sheet and the raw material constituting the artificial marble causes the lamella to be separated, the size and supply amount of the sheet in the marble are limited. Therefore, the transparent sheet cannot imitate the crystal grain of the natural marble. Application No. 491,874 discloses an artificial marble having an aliquot of artificial marble%, containing an aliquot of acrylic resin paste, 120 to 2 aliquots. a weight of the inorganic filler, H0 aliquot weight of the cross-linking agent and g.hg# part by weight of the polymerization initiator ^ and (B) 5 to 70 parts by weight of the marble f piece, then 1 aliquot of the weight Acrylic resin paste, 1GG~15G aliquot weight of inorganic filler, H0 aliquot weight crosslinking agent and g.hg aliquot weight polymerization initiator, wherein the mixing ratio of inorganic filler in artificial marble mud The mixing ratio of the marble flakes is 20 to 50 aliquots. The above patent discloses that the marble flakes obtained by adding the inorganic filler to the acrylic resin are opaque, so that the crystal grains in the natural marble or granite cannot be emulated. Therefore, in order to overcome the technical limitations of the above-described conventional artificial marble, the inventors have invented an artificial marble containing a transparent sheet which is coated with a transparent polymer having a high specific gravity resin layer such as acrylic resin or PET by a total of 200825034. Resin, which is formed by cutting the extrudate. Thus, the transparent flake has a specific gravity similar to that of the artificial marble raw material, and is similar to the transparency of quartz or high-purity cerium oxide in natural marble; thus, compared with The traditional artificial marble made of a thin sheet or a translucent single component can more closely resemble the pattern of natural marble. SUMMARY OF THE INVENTION [Technical Problem to be Solved] In the above problem, the object of the present invention is to provide a transparent sheet applied to artificial: stone, each of which is coated with a high specific gravity resin layer. On the outer surface of the layer, the high-specific gravity resin layer contains a filler, and the total specific gravity of the layer is adjusted to the specific gravity of the artificial marble material, thereby bermination. Hunting Artificial-type application of the transparent sheet of the f-opaque sheet of the 1 façade = grain and color aspects and the traditional inclusion of the stone. The marble has a clear distinction, and is more similar to the natural one. [Technical means for solving the problem] According to the invention, the 眚 _ artificial marble, the sample stalk is prepared by including the inner transparent layer (4). Each of the artificial marbles is formed in (4) the material layer is higher than the (four) layered proportion of the car. The father is better than the 'transparent thin or artificial marble raw materials that are different from the artificial marble raw materials. Sheet 7 200825034 ± 0.2g/cm3 or less. The artificial marble of the present invention is characterized in that the difference in specific gravity between the transparent sheet and the artificial marble raw material is minimized; preferably, the specific gravity of the transparent sheet is equal to the specific gravity of the raw material. When the difference in specific gravity between the transparent sheet and the artificial marble material is within the above range, the phenomenon of sheet separation does not occur. In order to produce an artificial marble which exhibits a permeability similar to that of quartz or high-purity oxidation in natural marble, and a pattern and color similar to that of natural marble, a transparent sheet is added to the artificial marble material. Γ In order to confirm the transparency of the transparent sheet, the filler is not added to the base resin such as an acrylic resin. Therefore, when a transparent sheet is applied to an artificial marble, a sheet separation phenomenon occurs due to a difference in specific gravity. -Yu, 疋' plastic resin has a specific gravity of 15g/cm3 or less, and the specific gravity of the C-tree is such as polymethyl methacrylate (pMMA), but the specific gravity of the artificial marble raw material is about疋1·4~1.8g/cm3. As the above, the specific gravity between the resin and the artificial marble raw material is poor: the transparent sheet of the field is made of the above resin and applied to the artificial marble, and the second sheet is separated. This is because there is no transparent polymer with L=6g/cm3), so there is no artificial marble. The difference in specific gravity between the two sheets of high-specific gravity formed on the surface of the transparent sheet is reduced. The lowest, so allow for the situation. , the same effect of natural quartz, without sheet separation 8 200825034 Preferably, the transparent sheet has an overall specific gravity of 13 to 2 〇g/cm3, which is similar to the specific gravity of the artificial marble raw material. Further, it is preferred that the outer layer has a specific gravity of 1.5 to 10 g/cm3, and the overall specific gravity of the transparent sheet is within the above range. The inner transparent layer has a light transmittance of 90 to 100%, preferably more than 95%. Conventional flakes contain a filler such as aluminum hydroxide and are therefore translucent and have a light transmission of less than 60%. The base resin for the inner transparent layer and the outer layer is a transparent polymer resin such as acrylic resin (PMMA), polyester resin, and polyethylene terephthalate. Preferably, the transparent sheet is a transparent acrylic sheet using an acrylic resin as a base resin. According to the present invention, a transparent acrylic sheet having a high specific gravity outer layer has high light transmittance and excellent physical properties, exhibits the same effect as a natural quartz flake, and is suitable for post treatment such as casting or polishing. The outer layer contains a filler for adjusting the specific gravity of the transparent sheet, and titanium dioxide, barium sulfate, aluminum hydroxide, calcium carbonate, barium oxide, metal powder and metal salt can be used as a suitable filler. The filler has a specific gravity of at least 2.5 g/cm3, preferably in the range of 25 to 1 〇g/cm3. In order to increase the adjustment effect of the specific gravity of each weight filler used, the filler has a high specific gravity. A third layer such as an adhesive layer or a primer layer for improving the adhesion between the inner transparent layer and the outer layer may be formed therebetween. The inner transparent layer may comprise a pearl dye. Then, the transparent sheet exhibits a pearl effect from the inside as well as on the surface, thus exhibiting a more impressive pearl effect than a conventional sheet which only exhibits a pearl effect on the surface. 200825034 The shape of the transparent sheet is not limited. A shape or a multi-faceted shape such as a four-sided and a six-sided shape: when the sheet has a cylindrical sheet, the transparent sheet has a cylindrical shape or a hexagonal surface, and is pressed out to make a transparent outer layer all or part of which is formed in the inner transparent sound and co-extruded to produce a transparent sheet. When the outer layer is on the surface. Although it is taken outside the entire outer surface. The cutting plane of the extrudate is in the appearance and plasticity of the transparent marble, preferably the size of the purchase:=°_, and the supply amount is other embodiments of the invention of the artificial marble marble, which provides the preparation of artificial large proportion The package:: The outer surface of the transparent layer of the r portion is formed with a higher specific gravity than the outer layer of Dejiang nl ^ and the product obtained by cutting and crushing, and then the (four) piece is added to the raw material of the artificial marble. = The specific gravity of the flakes can be adjusted to adjust the proportion of the filler added to the outer layer.

The process of manufacturing the transparent sheet 9 is: And 2 = transparent resin 1 is coextruded to form The layer is formed by forming a high (four)_6 co-extruded Γ 填 填 Π Π Π Π 压 压 压 压 压 压 压 = = = = = = = = = = 压 压 = = 压 压 压 压 = 压 压 压 压 压 压 = = 压 压 = = = = = = = = = Transparent layer 10 'main extrusion machine hopper 3, transparent resin 1 can penetrate the specific gravity layer 2 help: out of the auxiliary, use r, bucket 'into the 锸' f machine hopper 5' high specific gravity resin layer 6 can pass this "Ten Doo Into the auxiliary extruder 4; A name mouth, 7 m Α; ρ, ^, t 7 7, used to cool the obtained extrudate, knife ^, 8 for cutting the extrudate into a transparent sheet 9. For the transparent thin field made of at least two components having different specific gravities, a transparent resin for forming the inner transparent layer 1 and a high specific gravity resin 6 of the high specific gravity layer U. Transparent resin, = ancient weight And a transparent polymer having a light transmittance of 90% or more and a :H resin '·01 1 1 part by weight for a co-extruded release agent; a pearl dye required for C. The high specific gravity resin 6 is the same as the transparent resin 4 (10) An aliquot of a transparent polymer; and a high specific gravity filler for adjusting the thickness of the transparent thin 2 specific gravity G. Or a metal powder. When a polymer resin is used for co-extrusion, the initiator is not added. If necessary, a dye may be added. ^乂... A filler having a high specific gravity or a metal powder has a particle size of 1 〇 2 〇〇 _. The titanium salt or the metal salt i having a specific gravity of 2.5 or more is used and the metal powder is made of a copper or iron inorganic powder having a specific gravity of 2.5 or more. That is, any metal powder or metal salt having a ratio of i 2.5 * or more is used as a filling. The higher the specific gravity of the filler, the better the specific gravity can be effectively obtained by coating a small amount of the outer high-specific gravity layer 11 on the inner transparent layer 10, and exhibiting an improved effect. 1 In order to satisfy the above conditions, titanium dioxide, barium sulfate or a general metal salt is used as the filler, and copper powder or zinc powder is used as the metal powder. Generally, the polymer exhibits a transparent effect such as PMMA and ρΕτ, and can be used as a resin for producing the transparent sheet 9. Preferably, the acrylic sheet 9 is used to produce the transparent sheet 9 with an acrylic resin having improved physical properties (including transparency). G Thereafter, the resins 1 and 6 having different specific gravities were co-extruded via a co-extrusion machine at a temperature of ~~〇C and a speed of 20 m/min. The transparent resin 1 is supplied to the main extruder 2 through the main extruder hopper 3, ==_10. A high-assisted extruder hopper 5 containing a filler or a high specific gravity metal powder is supplied to the auxiliary extruder 4 to form an outer crucible layer 11. The general extrusion machine can be used as the main extrusion 200~3〇〇〇C of the pumping mountain ^ ώ m钺2 has the extrusion machine 4 and: = degree and 1~2〇-η extrusion speed. The auxiliary τ is produced in the same manner as the main extruder 2, and the extruding degree U and the speed of the extruding. It can be regarded as the main extruder 2 and the auxiliary extruder 4. The #得钱7 will be bathed in the cold bath by the main extruder 2 and the auxiliary extruder 4. In this way, the library is used; the cutting machine cuts into the same size of the transparent material with the same specific gravity; stone, and artificial marble, ten? Ϊ 4 pieces can be made. The above & co-extrusion is transparent, preferably 8 to 15 mm in diameter, 4 pieces having a diameter of 3 to 2 mm, and having a length of 3 to 20 mm, which is longer than 200825034 y Q mm. The outer high specific gravity layer 11 is coated on the inner transparent layer 1 of each of the sheets 9 to adjust the thickness and the amount of the mother. "The degree, according to the filler used, the length of the transparent sheet cut by the cutter 8 for the purpose of setting 2, 9 has 5~ and the size of the ancient seedling, the moon / #片9 When the transparent sheet 9 requires:, size, the transparent sheet 9 is crushed again, and the degree is classified to obtain a smaller sheet. The quality of the co-extrusion can be controlled according to the viscosity of the resin. The quality of the traditional extrusion: Tanning: The cross section of the transparent sheet 9 obtained by the co-extruding can be any shape that is shaped like a chevron, a triangle or a rectangle. Generally, the suitable transparent sheet 9 has a circular cross-sectional shape. , triangle and rectangle. The artificial marble made of the transparent sheet 9 having these shapes is excellent in appearance and effect. 〃 ,, the transparent sheet 9 manufactured by the above method is further mixed with the artificial marble raw material, and then The mixture is cast into the artificial marble template, as shown in Fig.: The mixing amount of the transparent sheet 9 and the artificial marble raw material is 1 to 50% of the total weight of the raw material, in addition to the artificial marble produced. The effect and plasticity are preferably from 5 to 20% by weight. Thereafter, the artificial marble slab is hardened 'and the surface of the artificial marble slab is sanded' to thereby produce an artificial marble finished product having a surface exposed to the sanded transparent sheet 12, such as The fourth figure shows the surface of the acrylic artificial marble manufactured above after hardening and sanding. As shown in the fourth figure, the transparent sheet 12 and the filler and its 14 200825034 are scattered in the sheet. In the artificial marble, it is not separated by the flakes. Therefore, the transparent flakes 12 exhibit a transparent effect, and the crystal grain in the near marble is so close that the artificial marble produced by the marble has a pattern of natural marble or granite. On the other hand, as shown in the fifth figure, in the 壬&Tashida containing the conventional artificial singularity of the single transparent sheet 13, the transparent sheet 13 is separated from the filler or other sheet due to the difference in weight. , , , , Γ In the second to fifth figures, the small gray piece represents a general sheet.

(4) I hunted the transparent soil made by the above method. Applying 10% by weight of transparent == 4 pieces of specific gravity. When making artificial marble by penetrating ruthenium, it will not be separated due to the weight difference (±〇.lg/cm3) which is heavier than 15 200825034. . Therefore, it can be obtained from high-quality artificial marble products. [Industrial Applicability] The traditional acrylic artificial marble is made of stone with a opaque or translucent color of the spider. The mouth is packed into a 'transparent crystal grain that cannot be imitated by natural flakes. ^ Marble, the traditional artificial marble appears to be earlier. In particular, conventional synthetic marbles containing opaque or translucent sheets are limited in their performance in color and pattern. In order to solve the above problem, the present invention provides a kind of artificial marble containing a transparent sheet which is transmitted by a hill, a mountain, a mountain, a mountain, a mountain, a mountain, a mountain, a mountain, a mountain, a mountain, a mountain, a mountain, a mountain, a mountain, a mountain, a Forming a relatively high specific gravity resin layer; such a transparent sheet has the same specific gravity as that of the artificial marble raw material, so that the difference in weight causes a delamination phenomenon and can exhibit the same transparent crystal grain or emulsified stone in natural marble. effect. Therefore, the artificial marble of the present invention can exhibit a pattern similar to natural marble and has an elegant appearance. Although a preferred embodiment of the present invention has been disclosed for the sake of explanation, it is understood that the person who knows this problem, § 19, can make various modifications under the field and spirit of the invention of the invention.
