特開２００４−２８４１１９号公報JP 2004-284119 A

ところで、前記金属調化粧シートは、熱可塑性樹脂基材層を介して木質、無機、及び金属基材にラッピング加工や真空成形によって貼付して用いられるものであるが、一方、押出樹脂成形に連続して樹脂成形品に貼付することにより、金属調化粧材の効率的な製造が要望されることがある。その場合、押出樹脂成形品は、押出成形後の開放空間における冷却に伴う収縮を含む変形を考慮して押出形状が設定されているのが通例である。   By the way, the metallic decorative sheet is used by being attached to a woody, inorganic, and metallic substrate through a thermoplastic resin substrate layer by lapping or vacuum forming. Then, there are cases in which efficient production of a metallic decorative material is desired by pasting on a resin molded product. In that case, the extruded resin molded product is usually set in an extruded shape in consideration of deformation including shrinkage accompanying cooling in an open space after extrusion molding.

しかしながら、前記金属調化粧シートでは、押出成形直後の高温状態におけるアルミニウム箔層と熱可塑性樹脂基材層との接着性が良いことから、変形し難いアルミニウム箔層の特性が金属調化粧シートの特性を代表するようになり、押出樹脂成形品に貼付されたとき、以下のような問題が生じることがある。すなわち、図４に一例を示すように、この金属調化粧シートを押出成形された高温状態の押出樹脂成形品３′に貼付すると、矢印ｘで示す面に貼付した場合には、変形し難いアルミニウム箔層が冷却に伴う押出樹脂成形品３′の変形を妨げて、二点鎖線で示す所望の仕上り形状や寸法が得られないおそれがあり、一方、矢印ｙで示す面に貼付した場合には、押出樹脂成形品３′の変形を妨げないものの、金属調化粧シートの皺等の外観不良が生じるおそれがある。   However, the metal-like decorative sheet has good adhesion between the aluminum foil layer and the thermoplastic resin base layer in a high-temperature state immediately after extrusion molding. When affixed to an extruded resin molded product, the following problems may occur. That is, as shown in an example in FIG. 4, when this metallic decorative sheet is affixed to an extruded resin molded product 3 'in a high temperature state, aluminum that is not easily deformed when affixed to the surface indicated by the arrow x. If the foil layer hinders the deformation of the extruded resin molded product 3 'accompanying cooling, the desired finished shape and dimensions indicated by the two-dot chain line may not be obtained. Although it does not hinder the deformation of the extruded resin molded product 3 ', there is a possibility that appearance defects such as wrinkles of the metallic decorative sheet may occur.

そこで、本発明は、樹脂成形品の押出成形に連続して貼付可能な金属調化粧シート、及び金属調化粧シートを樹脂成形品に貼付してなる金属調化粧材の提供を課題とする。   Therefore, an object of the present invention is to provide a metallic decorative sheet that can be applied continuously to extrusion molding of a resin molded product, and a metallic decorative material that is formed by attaching a metallic decorative sheet to a resin molded product.

前記課題を解決するため、本発明は次のように構成したことを特徴とする。   In order to solve the above problems, the present invention is configured as follows.

まず、請求項１に記載の発明は、熱可塑性樹脂基材層の一方の面に接着剤を介して積層されたアルミニウム箔層を有し、他方の面に接着層を有する金属調化粧シートであって、前記接着剤は、主剤と硬化剤とを混合して用いるもので、常温下で柔軟性を維持する比率で硬化剤が配合されたものであることを特徴とする。   First, the invention according to claim 1 is a metallic decorative sheet having an aluminum foil layer laminated on one surface of a thermoplastic resin base material layer via an adhesive and having an adhesive layer on the other surface. The adhesive is a mixture of a main agent and a curing agent, and is characterized in that the curing agent is blended in a ratio that maintains flexibility at room temperature.

次に、請求項２に記載の発明は、前記請求項１に記載の金属調化粧シートにおいて、前記アルミニウム箔層の表面に、接着剤を介して透明熱可塑性樹脂層が積層されており、前記接着剤は、主剤と硬化剤とを混合して用いるもので、常温下で柔軟性を維持する比率で硬化剤が配合されたものであることを特徴とする。   Next, the invention according to claim 2 is the metallic decorative sheet according to claim 1, wherein a transparent thermoplastic resin layer is laminated on the surface of the aluminum foil layer via an adhesive, The adhesive is a mixture of a main agent and a curing agent, and is characterized by being mixed with a curing agent in a ratio that maintains flexibility at room temperature.

そして、請求項３に記載の発明は、金属調化粧材であって、前記請求項１または請求項２に記載の金属調化粧シートが、前記熱可塑性樹脂基材層を挟んで前記アルミニウム箔層とは反対側の前記接着層を介して押出樹脂成形品に貼付されてなることを特徴とする。   The invention according to claim 3 is a metallic decorative material, wherein the metallic decorative sheet according to claim 1 or 2 includes the aluminum foil layer sandwiching the thermoplastic resin base material layer. It is affixed to the extrusion resin molded product through the said adhesive layer on the opposite side.

まず、請求項１に記載の発明によれば、この金属調化粧シートを、熱可塑性樹脂基材層を挟んでアルミニウム箔層とは反対側の接着層を介して、例えば押出成形に連続して樹脂成形品に貼付して用いることができる。   First, according to the first aspect of the present invention, the metallic decorative sheet is continuously formed by, for example, extrusion molding through the adhesive layer opposite to the aluminum foil layer with the thermoplastic resin base material layer interposed therebetween. It can be used by being affixed to a resin molded product.

その上で、熱可塑性樹脂基材層とアルミニウム箔層とを積層するための接着剤における主剤と硬化剤との配合を、常温下で柔軟性を維持する配合としたので、例えば押出成形直後の高い温度域にある樹脂成形品に貼付した場合には、金属調化粧シートは、アルミニウム箔層に拘束されることなく冷却に伴う樹脂成形品の変形に良好に追従する。その結果、所望の仕上り形状及び寸法の樹脂成形品が得られ、また、金属調化粧シートの皺等の外観不良が防止される。それに対し、接着剤に常温下で柔軟性を示さず完全硬化する配合のものを使用すると、この場合の金属調化粧シートは追従性に欠けるため、所望の仕上り形状及び寸法の樹脂成形品は得られず、また、金属調化粧シートの皺等の外観不良が生じるおそれがある。   In addition, since the blend of the main agent and the curing agent in the adhesive for laminating the thermoplastic resin base material layer and the aluminum foil layer is a blend that maintains flexibility at room temperature, for example, immediately after extrusion molding When affixed to a resin molded product in a high temperature range, the metallic decorative sheet follows the deformation of the resin molded product accompanying cooling without being constrained by the aluminum foil layer. As a result, a resin molded product having a desired finished shape and dimensions can be obtained, and appearance defects such as wrinkles on the metallic decorative sheet can be prevented. On the other hand, if an adhesive that does not exhibit flexibility at room temperature and is completely cured is used, the metal-like decorative sheet in this case lacks followability, so a resin molded product with a desired finished shape and dimensions can be obtained. In addition, appearance defects such as wrinkles of the metallic decorative sheet may occur.

次に、請求項２に記載の発明によれば、アルミニウム箔層の表面に前述したと同様の特徴的な接着剤を介して透明熱可塑性樹脂層を積層したので、アルミニウム箔層を保護し、且つアルミニウム箔層を設けたことによる金属調風合いを良好に維持することができる。そして、このような構成の金属調化粧シートにおいても、前記請求項１に記載の発明におけると同様に、押出成形直後の樹脂成形品に貼付した場合には、冷却に伴う樹脂成形品の変形に良好に追従するようになる。   Next, according to the invention described in claim 2, since the transparent thermoplastic resin layer is laminated on the surface of the aluminum foil layer through the same characteristic adhesive as described above, the aluminum foil layer is protected, In addition, the metallic texture due to the provision of the aluminum foil layer can be favorably maintained. And also in the metal-like decorative sheet having such a configuration, as in the invention of the first aspect, when pasted on a resin molded product immediately after extrusion, deformation of the resin molded product accompanying cooling is caused. Follows well.

そして、請求項３に記載の発明によれば、前記請求項１または請求項２に記載の金属調化粧シートが押出樹脂成形品に貼付されてなる金属調化粧材であるから、所望の仕上り形状及び寸法や、金属調化粧シートの皺等のない良好な外観が確実に得られる。   And according to the invention of Claim 3, since it is a metal-like decorative material in which the metal-like decorative sheet of Claim 1 or Claim 2 is affixed to an extruded resin molded product, a desired finished shape In addition, it is possible to reliably obtain a good appearance free from wrinkles and the like of the metal-like decorative sheet.

次に、金属調化粧材１の製造方法の一例について説明する。   Next, an example of the manufacturing method of the metallic tone decorative material 1 is demonstrated.

図２に示すように、製造ラインは、樹脂成形品３を押し出す押出機Ａと、図１で示した金属調化粧シート２を供給する金属調化粧シート供給装置Ｂと、供給された金属調化粧シート２を、プライマー層１５及び感熱接着剤層１６を介して高温状態の樹脂成形品３に熱圧着するためのラミネートロールＣと、金属調化粧シート２が樹脂成形品３に貼付されてなる金属調化粧材１を強制冷却する冷却装置Ｄとを有している。その場合、押し出されてラミネートロールＣに供給される樹脂成形品３の表面温度は１５０〜２５０℃である。   As shown in FIG. 2, the production line includes an extruder A that extrudes the resin molded product 3, a metallic decorative sheet supply device B that supplies the metallic decorative sheet 2 shown in FIG. 1, and the supplied metallic decorative makeup. A laminate roll C for thermocompression bonding the sheet 2 to the resin molded product 3 in a high temperature state via the primer layer 15 and the heat-sensitive adhesive layer 16, and a metal obtained by sticking the metallic decorative sheet 2 to the resin molded product 3 A cooling device D for forcibly cooling the decorative material 1. In that case, the surface temperature of the resin molded product 3 extruded and supplied to the laminate roll C is 150 to 250 ° C.

前記製造ラインを適用すれば、まず樹脂成形品３を押出成形し、押出成形された樹脂成形品３が高温域にある状態で、金属調化粧シート２を、熱可塑性樹脂基材層１１を挟んでアルミニウム箔層１２とは反対側のプライマー層１５、さらに感熱接着剤層１６を介して前記樹脂成形品３に貼付することができる。   If the said production line is applied, first, the resin molded product 3 is extrusion-molded, and the metal-like decorative sheet 2 is sandwiched between the thermoplastic resin base material layer 11 in a state where the extruded resin molded product 3 is in a high temperature range. Thus, it can be attached to the resin molded product 3 through the primer layer 15 on the side opposite to the aluminum foil layer 12 and the heat-sensitive adhesive layer 16.

以上のように構成したことにより、この金属調化粧シート２を、熱可塑性樹脂基材層１１を挟んでアルミニウム箔層１２とは反対側のプライマー層１５及び感熱接着剤層１６を介して、押出成形に連続して樹脂成形品３に貼付して用いることができる。   With this configuration, the metallic decorative sheet 2 is extruded through the primer layer 15 and the heat-sensitive adhesive layer 16 on the opposite side of the aluminum foil layer 12 with the thermoplastic resin base material layer 11 interposed therebetween. It can be used by being attached to the resin molded product 3 continuously after molding.

その上で、熱可塑性樹脂基材層１１とアルミニウム箔層１２とを、接着剤層１４を介して積層する際に、接着剤における主剤と硬化剤との配合を、常温下で柔軟性を維持する配合としたので、押出成形直後の高い温度域にある樹脂成形品３に貼付した場合には、金属調化粧シート２は、アルミニウム箔層１２に拘束されることなく冷却に伴う樹脂成形品３の変形に良好に追従する。その結果、所望の仕上り形状の樹脂成形品３が得られ、また、金属調化粧シート２の皺等の外観不良が防止される。それに対し、接着剤に常温下で柔軟性を示さず完全硬化する配合のものを使用すると、この場合の金属調化粧シートは追従性に欠けるため、所望の仕上り形状及び寸法の樹脂成形品は得られず、また、金属調化粧シートの皺等の外観不良が生じるおそれがある。   In addition, when the thermoplastic resin base material layer 11 and the aluminum foil layer 12 are laminated via the adhesive layer 14, the composition of the main agent and the curing agent in the adhesive is maintained at a normal temperature. Therefore, when affixed to a resin molded product 3 in a high temperature range immediately after extrusion molding, the metallic decorative sheet 2 is not restrained by the aluminum foil layer 12, and the resin molded product 3 accompanying cooling is used. Follows deformation well. As a result, a resin molded product 3 having a desired finished shape is obtained, and appearance defects such as wrinkles of the metallic decorative sheet 2 are prevented. On the other hand, if an adhesive that does not exhibit flexibility at room temperature and is completely cured is used, the metal-like decorative sheet in this case lacks followability, so a resin molded product with a desired finished shape and dimensions can be obtained. In addition, appearance defects such as wrinkles of the metallic decorative sheet may occur.

また、アルミニウム箔層１２の表面に前述したと同様の特徴的な接着剤を介して透明熱可塑性樹脂層１３を積層したので、アルミニウム箔層１２を保護し、且つアルミニウム箔層１２を設けたことによる金属調風合いを良好に維持することができる。そして、このような構成の金属調化粧シート２を押出成形直後の樹脂成形品に貼付する場合には、冷却に伴う樹脂成形品３の変形に良好に追従するようになる。   Moreover, since the transparent thermoplastic resin layer 13 was laminated on the surface of the aluminum foil layer 12 with the same characteristic adhesive as described above, the aluminum foil layer 12 was protected and the aluminum foil layer 12 was provided. It is possible to maintain a good metallic texture due to. And when sticking the metal-like decorative sheet 2 of such a structure to the resin molded product immediately after extrusion molding, it comes to follow well the deformation | transformation of the resin molded product 3 accompanying cooling.

また、前記金属調化粧シート２が樹脂成形品３に貼付されてなる金属調化粧材１であるから、所望の仕上り形状及び形状や、金属調化粧シート２の皺等のない良好な外観が確実に得られる。   In addition, since the metallic decorative sheet 2 is a metallic decorative material 1 that is affixed to the resin molded product 3, a desired finished shape and shape, and a good appearance without wrinkles of the metallic decorative sheet 2 are ensured. Is obtained.

（実施例１）
図３に示すようなＡＢＳ樹脂でなる樹脂成形品を押し出し、表面温度が１７０℃の樹脂成形品の矢印ｘで示す面に、厚みが５０μｍの半透明ＰＰ樹脂フィルム、厚みが９μｍの両面がヘアライン加工されたアルミニウム箔、及び厚みが１２μｍの透明ＰＥＴ樹脂フィルムを積層した構成の金属調化粧シートを貼付した。 Example 1
A resin molded product made of ABS resin as shown in FIG. 3 is extruded, and the surface indicated by arrow x of the resin molded product having a surface temperature of 170 ° C. is a translucent PP resin film having a thickness of 50 μm, and both surfaces having a thickness of 9 μm are hairlines. A metallic decorative sheet having a structure in which a processed aluminum foil and a transparent PET resin film having a thickness of 12 μm were laminated was pasted.

そして、積層する際の接着剤には、ポリエステル系接着剤を使用し、且つ主剤（東洋モートン（株）製ＴＫＳ−３９０９）１００部に対して硬化剤（東洋モートン（株）製ＣＡＴ−ＲＴ８５）７部を配合した。なお、この場合の硬化剤は、１６部が標準的比率であり、５部より少ないと硬化せず、１０部より多いと完全硬化し、５〜１０部の範囲内であると常温下で特徴的な金属調化粧シートとして好ましい柔軟性を維持するものである。   A polyester-based adhesive is used as an adhesive when laminating, and a curing agent (CAT-RT85 manufactured by Toyo Morton Co., Ltd.) with respect to 100 parts of the main agent (TKS-3909 manufactured by Toyo Morton Co., Ltd.). 7 parts were blended. In this case, the curing agent has a standard ratio of 16 parts, and when it is less than 5 parts, it is not cured, and when it is more than 10 parts, it is completely cured, and when it is within the range of 5 to 10 parts, it is characterized at room temperature. As a typical metal-like decorative sheet, the preferred flexibility is maintained.

また、金属調化粧シートにおける半透明ＰＰ樹脂フィルム側にプライマーを塗布し、さらに感熱型接着剤を塗布した。そして、貼付時の樹脂成形品の表面温度は１７０℃であった。その結果、金属調化粧シートは、冷却に伴う樹脂成形品の変形に良好に追従し、得られた金属調化粧材は、所望の仕上り形状及び寸法とされ、さらに、金属調化粧シートの皺等のない良好な外観が得られた。   A primer was applied to the translucent PP resin film side of the metallic decorative sheet, and a heat-sensitive adhesive was further applied. And the surface temperature of the resin molded product at the time of sticking was 170 degreeC. As a result, the metallic decorative sheet follows the deformation of the resin molded product with cooling well, and the obtained metallic decorative material has a desired finished shape and dimensions. A good appearance without any was obtained.

（実施例２）
厚みが７５μｍの半透明ＰＰ樹脂フィルム、厚みが９μｍの両面がヘアライン加工されたアルミニウム箔、及び厚みが２５μｍの透明ＰＥＴ樹脂フィルムを積層した構成の金属調化粧シートとしたことを除き、前記実施例１と同じである。この場合にも、金属調化粧シートは、冷却に伴う樹脂成形品の変形に良好に追従し、得られた金属調化粧材は、所望の仕上り形状及び寸法とされ、さらに、金属調化粧シートの皺等のない良好な外観が得られた。 (Example 2)
Example 1 except that a translucent PP resin film having a thickness of 75 μm, an aluminum foil having a thickness of 9 μm and hairline processed on both sides, and a metallic decorative sheet having a structure in which a transparent PET resin film having a thickness of 25 μm is laminated. Same as 1. In this case as well, the metallic decorative sheet follows the deformation of the resin molded product as it cools, and the resulting metallic decorative material has a desired finished shape and dimensions. A good appearance without wrinkles or the like was obtained.

（比較例）
半透明ＰＰ樹脂フィルム、アルミニウム箔、及び透明ＰＥＴ樹脂フィルムを積層する際の接着剤における主剤と硬化剤との配合比率に、主剤１００部に対して硬化剤１６部とする標準的な比率を採用したこと以外は、前記実施例１と同じである。この場合には、接着剤が完全硬化状態であるため、金属調化粧シートは、冷却に伴う樹脂成形品の変形に追従せず、得られた金属調化粧材は、所望の仕上り形状及び寸法には至らなかった。 (Comparative example)
A standard ratio of 16 parts of curing agent to 100 parts of main agent is adopted as the blending ratio of main agent and curing agent in the adhesive when laminating translucent PP resin film, aluminum foil, and transparent PET resin film. Except for the above, this is the same as Example 1. In this case, since the adhesive is in a completely cured state, the metallic decorative sheet does not follow the deformation of the resin molded product accompanying cooling, and the obtained metallic decorative material has a desired finished shape and dimensions. Did not come.

なお、本発明は、具体的に詳述した前記実施の形態に限定されることはなく、本発明の趣旨に沿うものであればよい。   It should be noted that the present invention is not limited to the above-described embodiment that has been specifically described in detail, and may be any that are within the spirit of the present invention.

例えば、透明熱可塑性樹脂層１３の表面に、さらに表面保護層を形成してもよい。また、その場合、表面保護層を構成することになる表面コート剤に着色顔料を混合して塗布することにより、色相の多様化を図ってもよい。   For example, a surface protective layer may be further formed on the surface of the transparent thermoplastic resin layer 13. In that case, the hue may be diversified by mixing and applying a color pigment to the surface coating agent that constitutes the surface protective layer.

以上説明したように、本発明によれば、樹脂成形品の押出成形に連続して貼付可能な金属調化粧シート、及び金属調化粧シートを樹脂成形品に貼付してなる金属調化粧材が提供され、本発明は、化粧シートの技術分野に広く好適である。   As described above, according to the present invention, there is provided a metallic decorative sheet that can be applied continuously to extrusion molding of a resin molded product, and a metallic decorative material formed by applying the metallic decorative sheet to a resin molded product.
