しかしながら、特許文献１に記載の加飾成形品の製造方法を、Ｃ−ＳＭＣ（Carbon fiber- Sheet Molding Compound）材料を用いて成形したＣ−ＳＭＣ成形品に対して加飾フィルムを貼り付けて加飾するものに適用すると、Ｃ−ＳＭＣ成形品の表面から炭素繊維（Carbon fiber）が露出している炭素繊維部分において接着剤が十分に機能せず、加飾フィルムがＣ−ＳＭＣ成形品から剥離してしまう可能性があるという問題がある。なお、Ｃ−ＳＭＣ成形品の表層には化学的性質の異なる炭素繊維部分と、樹脂部分がある。加飾フィルムを粘着剤によりＣ−ＳＭＣ成形品に接着すると、樹脂部分に対してはある程度の相互作用があり、Ｃ−ＳＭＣ成形品および加飾フィルムが互いに接着されるが、炭素繊維部分に対しては、相互作用がなく、粘着剤による接着が機能しない。Ｃ−ＳＭＣ成形品に加飾フィルムを熱融着により接着する場合も、炭素繊維部分に対しては、相互作用がなく、熱融着による接着が機能しない。したがって、Ｃ−ＳＭＣ成形品に加飾フィルムを接着しようとしても、剥離が起きてしまう。また、曲面追従性が高いため、Ｃ−ＳＭＣの表面凹凸に追従し、フィルム表面に同様の表面凹凸ができるため、フィルム表面の外観悪化につながる。 However, the method for producing a decorative molded product described in Patent Document 1 is applied by attaching a decorative film to a C-SMC molded product molded using a C-SMC (Carbon fiber-Sheet Molding Compound) material. When applied to decorative items, the adhesive does not function sufficiently at the carbon fiber portion where the carbon fiber is exposed from the surface of the C-SMC molded product, and the decorative film peels off from the C-SMC molded product. There is a problem that it may end up. The surface layer of the C-SMC molded product has a carbon fiber portion and a resin portion having different chemical properties. When the decorative film is adhered to the C-SMC molded product with an adhesive, there is some interaction with the resin portion, and the C-SMC molded product and the decorative film are adhered to each other, but with respect to the carbon fiber portion. There is no interaction and adhesive adhesion does not work. Even when the decorative film is adhered to the C-SMC molded product by heat fusion, there is no interaction with the carbon fiber portion, and the adhesion by heat fusion does not work. Therefore, even if an attempt is made to adhere the decorative film to the C-SMC molded product, peeling will occur. In addition, since it has high curved surface followability, it follows the surface unevenness of C-SMC and the same surface unevenness is formed on the film surface, which leads to deterioration of the appearance of the film surface.

本発明は、このような問題を解決するためになされたもので、Ｃ−ＳＭＣ成形品に対して加飾フィルムを接着する際に、十分な接着力を確保することができる加飾成形品の製造方法を提供することを課題とする。 The present invention has been made to solve such a problem, and is a decorative molded product capable of ensuring sufficient adhesive force when adhering a decorative film to a C-SMC molded product. An object is to provide a manufacturing method.

本発明に係る加飾成形品の製造方法は、Ｃ−ＳＭＣ材料を用いて成形したＣ−ＳＭＣ成形品に対して加飾する加飾成形品の製造方法であって、前記Ｃ−ＳＭＣ成形品は、前記Ｃ−ＳＭＣ材料からなるシートと、樹脂シートとを有し、前記シートとともに前記樹脂シートを同時に金型で加圧し成形することを特徴とする。 The method for producing a decorative molded product according to the present invention is a method for producing a decorative molded product for decorating a C-SMC molded product molded using a C-SMC material, and the C-SMC molded product. Is characterized in that it has a sheet made of the C-SMC material and a resin sheet, and the resin sheet is simultaneously pressed and molded by a mold together with the sheet.

本発明に係る加飾成形品の製造方法においては、Ｃ−ＳＭＣ成形品が、Ｃ−ＳＭＣ材料からなるシートと、樹脂シートとを同時に金型で加圧し成形される。その結果、シートと樹脂シートとが加圧されて、シートの炭素繊維が樹脂シートに入り込む効果、いわゆるアンカー効果により、シートと樹脂シートとに作用する接着力が十分に確保され、シートと樹脂シートとが強固に接着される。 In the method for producing a decorative molded product according to the present invention, a C-SMC molded product is molded by simultaneously pressing a sheet made of a C-SMC material and a resin sheet with a mold. As a result, the sheet and the resin sheet are pressurized, and the effect of the carbon fibers of the sheet entering the resin sheet, that is, the so-called anchor effect, sufficiently secures the adhesive force acting on the sheet and the resin sheet, and the sheet and the resin sheet. Is firmly adhered to.

本発明によれば、Ｃ−ＳＭＣ成形品に対して加飾フィルムを接着する際に、十分な接着力を確保することができる加飾成形品の製造方法を提供することができる。 According to the present invention, it is possible to provide a method for manufacturing a decorative molded product, which can secure a sufficient adhesive force when the decorative film is adhered to the C-SMC molded product.

本発明に係る加飾成形品の製造方法を適用した実施形態に係る加飾成形品１０の製造方法について図面を参照して説明する。まず、加飾成形品１０の製造方法により製造される加飾成形品１０について説明する。 The manufacturing method of the decorative molded article 10 according to the embodiment to which the manufacturing method of the decorative molded article according to the present invention is applied will be described with reference to the drawings. First, the decorative molded product 10 manufactured by the method for producing the decorative molded product 10 will be described.

加飾成形品１０は、図１（ａ）および図１（ｂ）に示すように、Ｃ−ＳＭＣ成形品１１と、加飾フィルム１２とにより構成されている。Ｃ−ＳＭＣ成形品１１は、シート２１と、樹脂シート２２とにより構成されている。シート２１は、Ｃ−ＳＭＣ材料からなり、所定の大きさおよび厚みを有する薄板である。 As shown in FIGS. 1A and 1B, the decorative molded product 10 is composed of the C-SMC molded product 11 and the decorative film 12. The C-SMC molded product 11 is composed of a sheet 21 and a resin sheet 22. The sheet 21 is a thin plate made of C-SMC material and having a predetermined size and thickness.

Ｃ−ＳＭＣ材料は、繊維強化材として炭素繊維が配合されており、ＳＭＣ（Sheet Molding Compound）と比較して高い弾性率を有し、成形品の厚みを薄くすることができる。 The C-SMC material contains carbon fiber as a fiber reinforcing material, has a high elastic modulus as compared with SMC (Sheet Molding Compound), and can reduce the thickness of the molded product.

樹脂シート２２は、所定の大きさおよび厚みを有する薄板からなり、シート２１と一体的に成形される。樹脂シート２２の材料は、後述する加飾フィルム１２のベース層に用いている材料と同じ材料からなる。具体的には、樹脂シート２２の材料は、アクリロニトリル、ブタジエン、スチレン共重合樹脂（ＡＢＳ、以下ＡＢＳという。）フィルムからなる。 The resin sheet 22 is made of a thin plate having a predetermined size and thickness, and is integrally molded with the sheet 21. The material of the resin sheet 22 is the same material as that used for the base layer of the decorative film 12 described later. Specifically, the material of the resin sheet 22 is composed of acrylonitrile, butadiene, and a styrene copolymer resin (ABS, hereinafter referred to as ABS) film.

加飾フィルム１２は、所定の大きさおよび厚みを有する薄膜からなり、Ｃ−ＳＭＣ成形品１１と加飾フィルム１２とを接着する図示しない接着層と、接着層に積層されたベース層と、ベース層に積層された加飾層と、加飾層に積層されたクリア層とにより構成されている。 The decorative film 12 is made of a thin film having a predetermined size and thickness, and has an adhesive layer (not shown) for adhering the C-SMC molded product 11 and the decorative film 12, a base layer laminated on the adhesive layer, and a base. It is composed of a decorative layer laminated on the layer and a clear layer laminated on the decorative layer.

接着層は、例えば、塩化ビニル、酢酸ビニル共重合樹脂に酸変性塩素化ポリプロピレン（酸変性塩素化ＰＰ）を含む接着剤からなる。ベース層は、ＡＢＳからなる。 The adhesive layer is made of, for example, an adhesive containing acid-modified chlorinated polypropylene (acid-modified chlorinated PP) in vinyl chloride or vinyl acetate copolymer resin. The base layer is made of ABS.

ベース層は、ＡＢＳ以外の材料、例えば、ポリ塩化ビニル（ＰＶＣ）、ポリプロピレン（ＰＰ）、ウレタン樹脂、アクリル樹脂、メラミン樹脂、エポキシ樹脂などの樹脂フィルムやシリコーン、ゴムであってもよい。 The base layer may be a material other than ABS, for example, a resin film such as polyvinyl chloride (PVC), polypropylene (PP), urethane resin, acrylic resin, melamine resin, epoxy resin, silicone, or rubber.

加飾層は、加飾フィルム１２に意匠を施すための層であり、例えば、アクリルウレタンからなる。クリア層は、加飾フィルム１２に耐傷性、耐候性を付与するための透明な層であり、例えば、透明なアクリルウレタンからなる。 The decorative layer is a layer for applying a design to the decorative film 12, and is made of, for example, acrylic urethane. The clear layer is a transparent layer for imparting scratch resistance and weather resistance to the decorative film 12, and is made of, for example, transparent acrylic urethane.

次いで、実施形態に係る加飾成形品１０の製造方法について、図面を参照して説明する。 Next, a method for manufacturing the decorative molded article 10 according to the embodiment will be described with reference to the drawings.

加飾成形品１０の製造方法は、図２（ａ）および図２（ｂ）に示すように、金型１００および図示しない熱融着冶具により行われる。金型１００は、上金型１０１および下金型１０２を備えており、上金型１０１および下金型１０２が閉じられた状態で、上金型１０１と下金型１０２との間にＣ−ＳＭＣ成形品１１と同様の空洞が形成される。 As shown in FIGS. 2A and 2B, the method for manufacturing the decorative molded product 10 is performed by using a mold 100 and a heat fusion jig (not shown). The mold 100 includes an upper mold 101 and a lower mold 102, and in a state where the upper mold 101 and the lower mold 102 are closed, the C- between the upper mold 101 and the lower mold 102. A cavity similar to that of the SMC molded product 11 is formed.

加飾成形品１０の製造方法は、準備工程と、成形工程と、取出工程と、接着工程とを含んで構成されており、各工程は、順に行われる。加飾成形品１０は、シート２１および樹脂シート２２を成形する工程、加飾フィルム１２をＣ−ＳＭＣ成形品に熱融着する工程を経て製造される。 The method for manufacturing the decorative molded product 10 includes a preparation step, a molding step, an extraction step, and an bonding step, and each step is performed in order. The decorative molded product 10 is manufactured through a step of molding the sheet 21 and the resin sheet 22 and a step of heat-sealing the decorative film 12 to the C-SMC molded product.

準備工程においては、加飾フィルム１２、シート２１および樹脂シート２２がそれぞれ製造される。次いで、シート２１および樹脂シート２２が重ね合わされ、図２（ａ）に示すように、樹脂シート２２が下金型１０２に対向し、シート２１が上金型１０１に対向するように下金型１０２の上に載置される。 In the preparatory step, the decorative film 12, the sheet 21, and the resin sheet 22 are manufactured, respectively. Next, the sheet 21 and the resin sheet 22 are superposed, and as shown in FIG. 2A, the lower mold 102 is such that the resin sheet 22 faces the lower mold 102 and the sheet 21 faces the upper mold 101. Placed on top of.

成形工程においては、シート２１および樹脂シート２２が下金型１０２に載置された状態で、図２（ｂ）に示すように、上金型１０１が矢印で示す重力方向に下降する。続いて、シート２１および樹脂シート２２が上金型１０１および下金型１０２により加圧され、シート２１および樹脂シート２２が一体化されたＣ−ＳＭＣ成形品１１が得られる。
取出工程においては、上金型１０１が上昇し、成形されたＣ−ＳＭＣ成形品１１が下金型１０２から取り出され、次工程に送られる。 In the molding step, the upper mold 101 descends in the direction of gravity indicated by the arrow, as shown in FIG. 2B, with the sheet 21 and the resin sheet 22 placed on the lower mold 102. Subsequently, the sheet 21 and the resin sheet 22 are pressed by the upper mold 101 and the lower mold 102 to obtain a C-SMC molded product 11 in which the sheet 21 and the resin sheet 22 are integrated.
In the take-out step, the upper mold 101 is raised, and the molded C-SMC molded product 11 is taken out from the lower mold 102 and sent to the next step.

接着工程においては、Ｃ−ＳＭＣ成形品１１および準備工程で製造された加飾フィルム１２が、図２（ｃ）に示すように、加飾フィルム１２の接着層がＣ−ＳＭＣ成形品１１の樹脂シート２２側に対向する姿勢で、図示しない熱融着冶具にセットされる。続いて、熱融着冶具により、Ｃ−ＳＭＣ成形品１１および加飾フィルム１２が加熱および加圧され、図２（ｄ）に示すように、Ｃ−ＳＭＣ成形品１１および加飾フィルム１２が一体化された加飾成形品１０が得られる。 In the bonding step, the C-SMC molded product 11 and the decorative film 12 manufactured in the preparatory step have the adhesive layer of the decorative film 12 as the resin of the C-SMC molded product 11, as shown in FIG. 2 (c). It is set in a heat-sealing jig (not shown) in a posture facing the seat 22 side. Subsequently, the C-SMC molded product 11 and the decorative film 12 are heated and pressurized by the heat fusion jig, and as shown in FIG. 2 (d), the C-SMC molded product 11 and the decorative film 12 are integrated. A modified decorative molded product 10 is obtained.

加飾成形品１０は、熱融着により一体化されることで、図３に示すように、Ｃ−ＳＭＣ成形品１１および加飾フィルム１２が強固に接着される。即ち、Ｃ−ＳＭＣ成形品１１を構成するシート２１の炭素繊維が樹脂シート２２に入り込む効果、いわゆるアンカー効果により、シート２１と樹脂シート２２とが強固に接着されている。 The decorative molded product 10 is integrated by heat fusion, so that the C-SMC molded product 11 and the decorative film 12 are firmly adhered to each other as shown in FIG. That is, the sheet 21 and the resin sheet 22 are firmly adhered to each other by the effect that the carbon fibers of the sheet 21 constituting the C-SMC molded product 11 enter the resin sheet 22, the so-called anchor effect.

また、樹脂シート２２は、加飾フィルム１２のベース層と同一の材料（本実施形態ではＡＢＳ）で形成されているので、樹脂シート２２は、加飾フィルム１２のベース層と一体化されている。加飾成形品１０の表面は、図３に示すように加飾フィルム１２のクリア層になっており、クリア層により加飾成形品１０に耐傷性、耐候性が付与されている。 Further, since the resin sheet 22 is made of the same material as the base layer of the decorative film 12 (ABS in this embodiment), the resin sheet 22 is integrated with the base layer of the decorative film 12. .. As shown in FIG. 3, the surface of the decorative molded product 10 is a clear layer of the decorative film 12, and the clear layer imparts scratch resistance and weather resistance to the decorative molded product 10.

以上のように構成された実施形態に係る加飾成形品１０の製造方法の効果について図面を参照して説明する。 The effect of the manufacturing method of the decorative molded article 10 according to the embodiment configured as described above will be described with reference to the drawings.

本実施形態に係る加飾成形品１０の製造方法は、Ｃ−ＳＭＣ材料を用いて成形したＣ−ＳＭＣ成形品１１に対して加飾する製造方法であって、Ｃ−ＳＭＣ成形品１１は、Ｃ−ＳＭＣ材料からなるシート２１と、樹脂シート２２とを有し、シート２１とともに樹脂シート２２が同時に金型１００で加圧されて一体化されることを特徴としている。 The method for manufacturing the decorative molded product 10 according to the present embodiment is a manufacturing method for decorating the C-SMC molded product 11 molded using the C-SMC material, and the C-SMC molded product 11 is a manufacturing method. It has a sheet 21 made of C-SMC material and a resin sheet 22, and is characterized in that the resin sheet 22 and the sheet 21 are simultaneously pressed by the mold 100 and integrated.

この構成により、シート２１と樹脂シート２２とが加圧されて、シート２１の炭素繊維が樹脂シート２２に入り込むアンカー効果により、シート２１および樹脂シート２２に作用する接着力が十分に確保され、シート２１と樹脂シート２２とが強固に接着されるという効果が得られる。また、樹脂シート２２は、加飾フィルム１２のベース層と同一のＡＢＳフィルムで形成されているので、樹脂シート２２は、加飾フィルム１２のベース層と強固に一体化されるという効果が得られる。また、シート２１の表面凹凸を樹脂シート２２が吸収し、樹脂シート２２の表面、さらにその上層表面では外観が向上する。 With this configuration, the sheet 21 and the resin sheet 22 are pressurized, and the adhesive force acting on the sheet 21 and the resin sheet 22 is sufficiently secured by the anchor effect in which the carbon fibers of the sheet 21 enter the resin sheet 22. The effect that the 21 and the resin sheet 22 are firmly adhered to each other can be obtained. Further, since the resin sheet 22 is formed of the same ABS film as the base layer of the decorative film 12, the effect that the resin sheet 22 is firmly integrated with the base layer of the decorative film 12 can be obtained. .. Further, the resin sheet 22 absorbs the surface irregularities of the sheet 21, and the appearance is improved on the surface of the resin sheet 22 and the surface of the upper layer thereof.

本実施形態に係る加飾成形品１０の製造方法は、従来の加飾成形品１の製造方法における問題を解消することができるという効果が得られる。即ち、従来の加飾成形品の製造方法は、図８（ａ）に示すように、金型２にＣ−ＳＭＣ材料からなるシート３がセットされ、図８（ｂ）に示すように、シート３のみが成形されていた。続いて、図８（ｃ）に示すように、金型２から取り出されたＣ−ＳＭＣ成形品４に対して、ホットメルト型接着層が形成された加飾フィルム５が熱融着により接着されていた。 The method for producing the decorative molded product 10 according to the present embodiment has an effect that the problem in the conventional method for producing the decorative molded product 1 can be solved. That is, in the conventional method for manufacturing a decorative molded product, as shown in FIG. 8A, a sheet 3 made of C-SMC material is set in the mold 2, and as shown in FIG. 8B, the sheet 3 is set. Only 3 was molded. Subsequently, as shown in FIG. 8C, the decorative film 5 on which the hot melt type adhesive layer is formed is bonded to the C-SMC molded product 4 taken out from the mold 2 by heat fusion. Was there.

その結果、Ｃ−ＳＭＣ成形品４の表面から炭素繊維が露出している炭素繊維部分において接着剤が十分に機能せず、加飾フィルム５がＣ−ＳＭＣ成形品４から剥離してしまう可能性があるという問題があった。具体的には、図４に示すように、従来の製造方法ではＡＢＳフィルムなしで加飾フィルム５を熱融着しているので、即ち、Ｃ−ＳＭＣ成形品４がシート３のみで成形されＣ−ＳＭＣ成形品４に加飾フィルム５が熱融着されているので、加飾フィルム５をＣ−ＳＭＣ成形品４に貼り付けた後にすぐに剥がれてしまい、付着性が×となった。 As a result, there is a possibility that the adhesive does not function sufficiently in the carbon fiber portion where the carbon fiber is exposed from the surface of the C-SMC molded product 4, and the decorative film 5 is peeled off from the C-SMC molded product 4. There was a problem that there was. Specifically, as shown in FIG. 4, in the conventional manufacturing method, the decorative film 5 is heat-sealed without the ABS film, that is, the C-SMC molded product 4 is molded only by the sheet 3 and C. Since the decorative film 5 was heat-sealed to the -SMC molded product 4, the decorative film 5 was immediately peeled off after being attached to the C-SMC molded product 4, and the adhesiveness became x.

これに対して、本実施形態に係る加飾成形品１０の製造方法によれば、シート２２にＡＢＳフィルムを一体成形した後に、加飾フィルム１２を熱融着しているので、即ち、Ｃ−ＳＭＣ成形品１１がＣ−ＳＭＣ材料からなるシート２１と、ＡＢＳからなる樹脂シート２２とが一体成形されているので、碁盤目試験において合格となり、付着性が〇となった。 On the other hand, according to the method for producing the decorative molded product 10 according to the present embodiment, the decorative film 12 is heat-sealed after the ABS film is integrally molded on the sheet 22, that is, C-. Since the SMC molded product 11 is integrally molded with the sheet 21 made of C-SMC material and the resin sheet 22 made of ABS, it passed the grid test and the adhesiveness was 〇.

したがって、本実施形態に係る加飾成形品１０の製造方法は、従来の加飾成形品の製造方法における問題を解消することができるという効果が得られた。 Therefore, the method for producing the decorative molded product 10 according to the present embodiment has an effect that the problem in the conventional method for producing the decorative molded product can be solved.

なお、本実施形態に係る加飾成形品１０の製造方法においては、Ｃ−ＳＭＣ成形品１１の樹脂シート２２の材料をＡＢＳフィルムで構成し、熱融着により加飾フィルム１２をＣ−ＳＭＣ成形品１１に接着した場合について説明した。 In the method for manufacturing the decorative molded product 10 according to the present embodiment, the material of the resin sheet 22 of the C-SMC molded product 11 is made of an ABS film, and the decorative film 12 is C-SMC molded by heat fusion. The case where it is adhered to the product 11 has been described.

The material of the resin sheet 22A is the same material as that used for the base layer of the decorative film 12A described later. Specifically, the material of the resin sheet 22A is made of a polyvinyl chloride (PVC) film.

加飾フィルム１２Ａは、実施形態の加飾フィルム１２と同様、所定の大きさおよび厚みを有する薄膜からなり、Ｃ−ＳＭＣ成形品と加飾フィルム１２とを接着する図示しない接着層と、接着層に積層されたベース層と、ベース層に積層された加飾層と、加飾層に積層されたクリア層とにより構成されている。 Like the decorative film 12 of the embodiment, the decorative film 12A is made of a thin film having a predetermined size and thickness, and has an adhesive layer (not shown) for adhering the C-SMC molded product and the decorative film 12 and an adhesive layer. It is composed of a base layer laminated on the base layer, a decorative layer laminated on the base layer, and a clear layer laminated on the decorative layer.

接着層は、アクリル系の粘着剤からなり、ベース層は、ポリ塩化ビニル（ＰＶＣ）からなる。なお、ベース層は、ポリ塩化ビニル（ＰＶＣ）以外の材料、例えば、ポリプロピレン（ＰＰ）、ウレタン樹脂、アクリル樹脂、メラミン樹脂、エポキシ樹脂などの樹脂フィルムやシリコーン、ゴムであってもよい。 The adhesive layer is made of an acrylic pressure-sensitive adhesive, and the base layer is made of polyvinyl chloride (PVC). The base layer may be a material other than polyvinyl chloride (PVC), for example, a resin film such as polypropylene (PP), urethane resin, acrylic resin, melamine resin, or epoxy resin, silicone, or rubber.

次いで、実施形態に係る加飾成形品１０Ａの製造方法について、図面を参照して説明する。 Next, a method for manufacturing the decorative molded product 10A according to the embodiment will be described with reference to the drawings.

加飾成形品１０Ａの製造方法は、実施形態に係る加飾成形品１０と同様、図６（ａ）および図６（ｂ）に示すように、金型１００および手貼りにより行われる。なお、図示しない熱融着冶具を用いてもよい。 The method for producing the decorative molded product 10A is the same as that of the decorative molded product 10 according to the embodiment, as shown in FIGS. 6 (a) and 6 (b), by using the mold 100 and hand-pasting. A heat fusion jig (not shown) may be used.

加飾成形品１０の製造方法は、実施形態に係る加飾成形品１０と同様、準備工程と、成形工程と、取出工程と、接着工程とを含んで構成されており、各工程は、順に行われる。加飾成形品１０は、シート２１および樹脂シート２２Ａを成形する工程、加飾フィルム１２ＡをＣ−ＳＭＣ成形品に熱融着する工程を経て製造される。 The manufacturing method of the decorative molded product 10 includes a preparation step, a molding step, an extraction step, and an adhesion step, as in the case of the decorative molded product 10 according to the embodiment, and each step is in order. Will be done. The decorative molded product 10 is manufactured through a step of molding the sheet 21 and the resin sheet 22A, and a step of heat-sealing the decorative film 12A to the C-SMC molded product.

準備工程においては、加飾フィルム１２Ａ、シート２１および樹脂シート２２Ａがそれぞれ製造される。次いで、シート２１および樹脂シート２２Ａが重ね合わされ、図６（ａ）に示すように、樹脂シート２２Ａが下金型１０２に対向し、シート２１が上金型１０１に対向するように下金型１０２の上に載置される。 In the preparatory step, the decorative film 12A, the sheet 21, and the resin sheet 22A are manufactured, respectively. Next, the sheet 21 and the resin sheet 22A are overlapped with each other, and as shown in FIG. 6A, the lower mold 102 faces the lower mold 102 and the sheet 21 faces the upper mold 101. Placed on top of.

成形工程においては、シート２１および樹脂シート２２Ａが載置された状態で、図６（ｂ）に示すように、上金型１０１が矢印で示す重力方向に下降する。続いて、シート２１および樹脂シート２２Ａが上金型１０１および下金型１０２により加圧され、シート２１および樹脂シート２２Ａが一体化されたＣ−ＳＭＣ成形品１１Ａが得られる。 In the molding step, with the sheet 21 and the resin sheet 22A placed on the sheet, the upper mold 101 descends in the direction of gravity indicated by the arrow, as shown in FIG. 6B. Subsequently, the sheet 21 and the resin sheet 22A are pressed by the upper mold 101 and the lower mold 102 to obtain a C-SMC molded product 11A in which the sheet 21 and the resin sheet 22A are integrated.

取出工程においては、上金型１０１が上昇し、成形されたＣ−ＳＭＣ成形品１１Ａが下金型１０２から取り出され、所定の場所に載置される。 In the taking-out step, the upper mold 101 is raised, and the molded C-SMC molded product 11A is taken out from the lower mold 102 and placed in a predetermined place.

接着工程においては、Ｃ−ＳＭＣ成形品１１Ａおよび準備工程で製造された加飾フィルム１２Ａが、図６（ｃ）に示すように、加飾フィルム１２Ａの接着層がＣ−ＳＭＣ成形品１１Ａの樹脂シート２２Ａ側に対向する姿勢で、手貼りによりＣ−ＳＭＣ成形品１１Ａに貼り付けられる。これにより、図６（ｄ）に示すように、Ｃ−ＳＭＣ成形品１１Ａおよび加飾フィルム１２Ａが一体化された加飾成形品１０Ａが得られる。 In the bonding step, the C-SMC molded product 11A and the decorative film 12A produced in the preparatory step have the adhesive layer of the decorative film 12A as the resin of the C-SMC molded product 11A, as shown in FIG. 6 (c). It is attached to the C-SMC molded product 11A by hand in a posture facing the sheet 22A side. As a result, as shown in FIG. 6D, a decorative molded product 10A in which the C-SMC molded product 11A and the decorative film 12A are integrated is obtained.

なお、接着工程においては、手貼りに代えて、熱融着冶具により接着するようにしてもよい。熱融着冶具を用いる場合には、実施形態と同様、加飾フィルム１２Ａの接着層がＣ−ＳＭＣ成形品１１Ａの樹脂シート２２Ａ側に対向する姿勢で、図示しない熱融着冶具にセットされる。続いて、熱融着冶具により、Ｃ−ＳＭＣ成形品１１Ａおよび加飾フィルム１２Ａを加熱および加圧する。これにより、図６（ｄ）に示すように、Ｃ−ＳＭＣ成形品１１Ａおよび加飾フィルム１２Ａが一体化された加飾成形品１０Ａが得られる。 In the bonding step, the bonding may be performed by a heat fusion jig instead of the manual bonding. When a heat fusion jig is used, the adhesive layer of the decorative film 12A is set on the heat fusion jig (not shown) in a posture facing the resin sheet 22A side of the C-SMC molded product 11A, as in the embodiment. .. Subsequently, the C-SMC molded product 11A and the decorative film 12A are heated and pressurized by the heat fusion jig. As a result, as shown in FIG. 6D, a decorative molded product 10A in which the C-SMC molded product 11A and the decorative film 12A are integrated is obtained.

加飾成形品１０Ａは、手貼りまたは熱融着により一体化されることで、Ｃ−ＳＭＣ成形品１１Ａおよび加飾フィルム１２Ａが強固に接着される。即ち、Ｃ−ＳＭＣ成形品１１Ａを構成するシート２１の炭素繊維が樹脂シート２２Ａに入り込むアンカー効果により、シート２１と樹脂シート２２Ａとが強固に接着されている。 The decorative molded product 10A is integrated by hand sticking or heat fusion, so that the C-SMC molded product 11A and the decorative film 12A are firmly adhered to each other. That is, the sheet 21 and the resin sheet 22A are firmly adhered to each other by the anchor effect in which the carbon fibers of the sheet 21 constituting the C-SMC molded product 11A enter the resin sheet 22A.

また、樹脂シート２２Ａは、加飾フィルム１２Ａのベース層と同一のＰＶＣフィルムで形成されているので、樹脂シート２２Ａは、加飾フィルム１２Ａのベース層と一体化される。 Further, since the resin sheet 22A is formed of the same PVC film as the base layer of the decorative film 12A, the resin sheet 22A is integrated with the base layer of the decorative film 12A.

以上のように構成された実施形態の変形例に係る加飾成形品１０Ａの製造方法の効果について図面を参照して説明する。 The effect of the manufacturing method of the decorative molded product 10A according to the modified example of the embodiment configured as described above will be described with reference to the drawings.

本実施形態の変形例に係る加飾成形品１０Ａの製造方法は、Ｃ−ＳＭＣ材料を用いて成形したＣ−ＳＭＣ成形品１１Ａに対して加飾する製造方法であって、Ｃ−ＳＭＣ成形品１１Ａは、Ｃ−ＳＭＣ材料からなるシート２１と、樹脂シート２２Ａとを有し、シート２１とともに樹脂シート２２Ａが同時に金型１００で加圧されて一体化されることを特徴としている。 The method for manufacturing the decorative molded product 10A according to the modification of the present embodiment is a manufacturing method for decorating the C-SMC molded product 11A molded using the C-SMC material, and is a C-SMC molded product. The 11A has a sheet 21 made of a C-SMC material and a resin sheet 22A, and is characterized in that the resin sheet 22A and the sheet 21 are simultaneously pressed by the mold 100 and integrated.

この構成により、実施形態に係る加飾成形品１０と同様、シート２１と樹脂シート２２Ａとが加圧されて、シート２１の炭素繊維が樹脂シート２２Ａに入り込むアンカー効果により、シート２１および樹脂シート２２Ａに作用する接着力が十分に確保され、シート２１と樹脂シート２２Ａとが強固に接着されるという効果が得られる。また、樹脂シート２２Ａは、加飾フィルム１２Ａのベース層と同一材料のＰＶＣで形成されているので、樹脂シート２２Ａは、加飾フィルム１２Ａのベース層と強固に一体化されるという効果が得られる。また、シート２１の表面凹凸を樹脂シート２２Ａが吸収し、樹脂シート２２Ａの表面、さらにその上層表面では外観が向上するという効果が得られる。 With this configuration, as in the decorative molded product 10 according to the embodiment, the sheet 21 and the resin sheet 22A are pressurized, and the carbon fibers of the sheet 21 enter the resin sheet 22A due to the anchor effect of the sheet 21 and the resin sheet 22A. The adhesive force acting on the resin sheet 21 is sufficiently secured, and the effect that the sheet 21 and the resin sheet 22A are firmly adhered to each other can be obtained. Further, since the resin sheet 22A is made of PVC made of the same material as the base layer of the decorative film 12A, the effect that the resin sheet 22A is firmly integrated with the base layer of the decorative film 12A can be obtained. .. Further, the resin sheet 22A absorbs the surface irregularities of the sheet 21, and the effect of improving the appearance on the surface of the resin sheet 22A and the surface of the upper layer thereof can be obtained.

本実施形態の変形例に係る加飾成形品１０Ａの製造方法においても、本実施形態に係る加飾成形品１０の製造方法と同様、従来の加飾成形品の製造方法における問題を解消することができるという効果が得られる。 Also in the method for producing the decorative molded product 10A according to the modified example of the present embodiment, the problem in the conventional method for producing the decorative molded product is solved as in the method for producing the decorative molded product 10 according to the present embodiment. The effect of being able to do is obtained.

具体的には、図７に示すように、従来の製造方法ではＰＶＣフィルムなしで加飾フィルム５を手貼りまたは熱融着を行っているので、即ち、Ｃ−ＳＭＣ成形品４がシート３のみで成形され、Ｃ−ＳＭＣ成形品４に加飾フィルム５が熱融着または手貼りが行われているので、加飾フィルム５をＣ−ＳＭＣ成形品４に貼り付けた後にすぐに剥がれてしまい碁盤目試験において、付着性が×となった。 Specifically, as shown in FIG. 7, in the conventional manufacturing method, the decorative film 5 is manually attached or heat-sealed without the PVC film, that is, the C-SMC molded product 4 is only the sheet 3. Since the decorative film 5 is heat-sealed or manually attached to the C-SMC molded product 4, the decorative film 5 is immediately peeled off after being attached to the C-SMC molded product 4. In the grid test, the adhesiveness was x.

これに対して、本実施形態の変形例に係る加飾成形品１０Ａの製造方法によれば、ＰＶＣフィルムを一体成形後に加飾フィルム１２Ａを手貼りまたは熱融着を行っているので、即ち、Ｃ−ＳＭＣ成形品１１ＡがＣ−ＳＭＣ材料からなるシート２１と、ＰＶＣからなる樹脂シート２２Ａとが一体成形されているので、碁盤目試験において合格となり、付着性が〇となった。 On the other hand, according to the method for producing the decorative molded product 10A according to the modified example of the present embodiment, the decorative film 12A is manually pasted or heat-sealed after the PVC film is integrally molded, that is, that is, Since the C-SMC molded product 11A is integrally molded with the sheet 21 made of the C-SMC material and the resin sheet 22A made of PVC, it passed the grid test and the adhesiveness became 〇.

したがって、本実施形態の変形例に係る加飾成形品１０Ａの製造方法は、従来の加飾成形品の製造方法における問題を解消することができるという効果が得られた。 Therefore, the method for producing the decorative molded product 10A according to the modified example of the present embodiment has an effect that the problem in the conventional method for producing the decorative molded product can be solved.
