Description

本発明は、基材を樹脂シートで被覆した樹脂シート被覆製品の製造方法及びこれを用いて製造された樹脂シート被覆製品に関する。   The present invention relates to a method for producing a resin sheet coated product in which a substrate is coated with a resin sheet, and a resin sheet coated product produced using the method.

基材を樹脂シートで被覆した樹脂シート被覆製品の製造方法として、基材に対して樹脂シートを当接させた後、真空成型と圧空成型を行い、樹脂シートを基材に張り付けるものがある（例えば特許文献１参照）。   As a method of manufacturing a resin sheet-coated product in which a base material is coated with a resin sheet, there is a method in which a resin sheet is brought into contact with the base material, and then vacuum molding and pressure molding are performed to attach the resin sheet to the base material. (For example, refer to Patent Document 1).

特開２００２−６７１３７JP 2002-67137 A

しかしながら、樹脂シートを基材に当接させて真空成型と圧空成型を行うとき、基材上の空気を樹脂シートで覆ってしまうと、基材と樹脂シートとの間に膨れという空気だまりができたり、樹脂シート被覆製品の表面の模様にムラができてしまったりする。   However, when vacuum molding and pressure molding are performed with the resin sheet in contact with the base material, if the air on the base material is covered with the resin sheet, an air pool of swelling between the base material and the resin sheet can be created. Or the surface pattern of the resin sheet-coated product is uneven.

そこで本発明の目的は、樹脂シート被覆製品の表面を、空気だまりや模様のムラがなく、平滑性の高いものにすることである。   Accordingly, an object of the present invention is to make the surface of a resin sheet-coated product highly smooth without air accumulation and pattern unevenness.

図を用いて本発明の第１実施形態を説明する。 [First Embodiment]
A first embodiment of the present invention will be described with reference to the drawings.

（樹脂シート被覆製品１０の構成）
図１及び図２を用いて第１実施形態における樹脂シート被覆製品１０の構成を説明する。図１は第１実施形態における樹脂シート被覆製品１０の斜視図である。図２は第１実施形態における樹脂シート被覆製品１０の断面図である。 (Configuration of resin sheet coated product 10)
The configuration of the resin sheet-covered product 10 in the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view of a resin sheet-coated product 10 according to the first embodiment. FIG. 2 is a cross-sectional view of the resin sheet-coated product 10 according to the first embodiment.

図１及び図２に示すように、樹脂シート被覆製品１０は、樹脂シート１１によって基材１２を被覆することで構成される。   As shown in FIGS. 1 and 2, the resin sheet-covered product 10 is configured by covering a base material 12 with a resin sheet 11.

樹脂シート１１は、本実施形態においては表面・裏面とも平滑なものを用いる。樹脂シート１１の基材１２との対向面１１ａには、接着剤が塗布されている。   In the present embodiment, the resin sheet 11 has a smooth surface and back surface. An adhesive is applied to the surface 11 a of the resin sheet 11 that faces the substrate 12.

基材１２は、樹脂又は金属によって構成される。図２（ａ）に示すように、基材１２の樹脂シート１１との対向面１２ａは、表面加工によって微細な凹凸面となる。微細な凹凸面となることで、樹脂シート１１を張り合わせるときに、樹脂シート１１と基材１２との間に介在する空気を前記微細な凹凸面から外部へ逃がすことができる。これにより、樹脂シート１１と基材１２とを張り合わせたときに、樹脂シート１１と基材１２との間に空気がたまることを防ぎ、樹脂シート被覆製品の表面を、空気だまりや模様のムラがなく、平滑性の高いものにすることができる。   The substrate 12 is made of resin or metal. As shown to Fig.2 (a), the opposing surface 12a with the resin sheet 11 of the base material 12 turns into a fine uneven surface by surface processing. By forming the fine uneven surface, the air interposed between the resin sheet 11 and the base material 12 can be released from the fine uneven surface to the outside when the resin sheet 11 is laminated. Thereby, when the resin sheet 11 and the base material 12 are bonded together, air is prevented from accumulating between the resin sheet 11 and the base material 12, and the surface of the resin sheet-coated product is free of air accumulation and pattern unevenness. And high smoothness.

尚、微細な凹凸面は、最大高さＲｙ〔μｍ〕が、１．６≦Ｒｙ≦１００の範囲が好ましい。最大高さＲｙが１．６よりも小さいと空気を外部に逃がすことが困難となり、最大高さＲｙが１００よりも大きいと樹脂シート１１の接着剤の接着性が悪くなる。   The fine uneven surface preferably has a maximum height Ry [μm] in the range of 1.6 ≦ Ry ≦ 100. When the maximum height Ry is smaller than 1.6, it is difficult to let air escape to the outside, and when the maximum height Ry is larger than 100, the adhesiveness of the adhesive of the resin sheet 11 is deteriorated.

（樹脂シート被覆製品１０の製造方法）
図３を用いて樹脂シート被覆製品１０の製造方法を説明する。図３は樹脂シート被覆製品１０の製造手順を説明する図である。 (Manufacturing method of resin sheet coated product 10)
A method for producing the resin sheet-covered product 10 will be described with reference to FIG. FIG. 3 is a diagram for explaining the manufacturing procedure of the resin sheet-coated product 10.

まず、樹脂シート被覆製品１０の製造装置５０の概略構成を説明する。製造装置５０は、上成型室５１及び下成型室５２を有する。上成型室５１と下成型室５２はそれぞれ、駆動装置５１ａ、駆動装置５２ａを有する。   First, a schematic configuration of the manufacturing apparatus 50 for the resin sheet coated product 10 will be described. The manufacturing apparatus 50 includes an upper molding chamber 51 and a lower molding chamber 52. Each of the upper molding chamber 51 and the lower molding chamber 52 includes a driving device 51a and a driving device 52a.

下成型室５２の底部には、基材１２を固定するテーブル５４が配設される。下成型室５２の上成型室５１側端部には、樹脂シート１１を挟持するクランプ５３が配設される。また、上成型室５１と下成型室５２の側面には、空気を吸引する真空タンク５５と、圧縮空気を送る圧空タンク５６とが配設される。また、上成型室５１の内側上部にはヒーター５７が配設される。   A table 54 for fixing the base material 12 is disposed at the bottom of the lower molding chamber 52. A clamp 53 that sandwiches the resin sheet 11 is disposed at the upper molding chamber 51 side end of the lower molding chamber 52. A vacuum tank 55 for sucking air and a compressed air tank 56 for sending compressed air are disposed on the side surfaces of the upper molding chamber 51 and the lower molding chamber 52. In addition, a heater 57 is disposed in the upper part inside the upper molding chamber 51.

ここで、基材１２の樹脂シート１１との対向面１２ａは、図２（ａ）に示すように、微細な凹凸面となっている。   Here, the opposing surface 12a of the substrate 12 facing the resin sheet 11 is a fine uneven surface as shown in FIG.

図３（ａ）に示すように、まず、上成型室５１を開放した状態で、下成型室５２のテーブル５４に基材１２を設置する。また、下成型室５２の上端において、樹脂シート１１をクランプ５３で挟持する。   As shown in FIG. 3A, first, the base material 12 is set on the table 54 of the lower molding chamber 52 with the upper molding chamber 51 opened. Further, the resin sheet 11 is clamped by the clamp 53 at the upper end of the lower molding chamber 52.

図３（ｂ）に示すように、駆動装置５１ａを起動させて上成型室５１を降下させ、上成型室５１を下成型室５２に当接させる。これにより、上成型室５１及び下成型室５２で覆われた空間は機密状態になる。   As shown in FIG. 3B, the driving device 51 a is activated to lower the upper molding chamber 51 and bring the upper molding chamber 51 into contact with the lower molding chamber 52. Thereby, the space covered with the upper molding chamber 51 and the lower molding chamber 52 is in a confidential state.

図３（ｃ）に示すように、下成型室５２のテーブル５４を上昇させると、テーブル５４上の基材１２の上面が樹脂シート１１に当接する。そして、真空タンク５５により、上成型室５１及び下成型室５２内から空気を抜くと、上成型室５１及び下成型室５２の内部は真空状態となる。ここで、ヒーター５７を点灯し、樹脂シート１１の加熱を行う。これにより、樹脂シート１１が軟化し、また接着剤の接着性も向上する。   As shown in FIG. 3C, when the table 54 in the lower molding chamber 52 is raised, the upper surface of the base material 12 on the table 54 comes into contact with the resin sheet 11. Then, when air is extracted from the upper molding chamber 51 and the lower molding chamber 52 by the vacuum tank 55, the inside of the upper molding chamber 51 and the lower molding chamber 52 is in a vacuum state. Here, the heater 57 is turned on to heat the resin sheet 11. Thereby, the resin sheet 11 is softened and the adhesiveness of the adhesive is also improved.

図３（ｄ）に示すように、上成型室５１のみを大気圧にすると、図中実線のように空気が流れる。このとき、下成型室５２が真空であるため、上成型室５１にある樹脂シート１１側から下成型室５２基材１２に対して圧力がかかる。また、圧空タンク５６から圧縮空気を入れると、上成型室５１から下成型室５２に対して更に大きな圧力がかかる。   As shown in FIG. 3D, when only the upper molding chamber 51 is at atmospheric pressure, air flows as shown by a solid line in the figure. At this time, since the lower molding chamber 52 is in a vacuum, pressure is applied to the lower molding chamber 52 base 12 from the resin sheet 11 side in the upper molding chamber 51. Further, when compressed air is introduced from the pressurized air tank 56, a larger pressure is applied from the upper molding chamber 51 to the lower molding chamber 52.

ここで、樹脂シート１１の基材１２側の対向面１１ａには、接着剤が塗布されている。この接着剤により、上成型室５１から下成型室５２に圧力がかかったときに、樹脂シート１１と基材１２とが一体的に張り合わされ、樹脂シート被覆製品１０が形成される。   Here, an adhesive is applied to the facing surface 11a of the resin sheet 11 on the base 12 side. When pressure is applied from the upper molding chamber 51 to the lower molding chamber 52 by the adhesive, the resin sheet 11 and the base material 12 are integrally bonded to form the resin sheet-coated product 10.

樹脂シート１１と基材１２とが張り合わされるとき、基材１２の樹脂シート１１との対向面１２ａには微細な凹凸面が形成されている。このため、樹脂シート１１が基材１２表面に張り合わされるとき、樹脂シート１１と基材１２との間の空気がこの微細な凹凸面から逃げる。すると、樹脂シート１１の接着剤が塗布された面と基材１２の対向面１２ａとが密着する。これにより、樹脂シート被覆製品１０の表面を、空気だまりや模様のムラがなく、平滑性の高いものにすることができる。   When the resin sheet 11 and the base material 12 are bonded together, a fine uneven surface is formed on the facing surface 12a of the base material 12 facing the resin sheet 11. For this reason, when the resin sheet 11 is stuck to the surface of the base material 12, the air between the resin sheet 11 and the base material 12 escapes from this fine uneven surface. Then, the surface of the resin sheet 11 on which the adhesive is applied and the facing surface 12a of the substrate 12 are brought into close contact with each other. As a result, the surface of the resin sheet-covered product 10 can be made highly smooth without air accumulation and pattern irregularities.

〔第２実施形態〕
図を用いて本発明の第２実施形態を説明する。 [Second Embodiment]
A second embodiment of the present invention will be described with reference to the drawings.

（樹脂シート被覆製品２０の構成）
図４及び図５を用いて第２実施形態における樹脂シート被覆製品２０の構成を説明する。図４は第２実施形態における樹脂シート被覆製品２０の斜視図である。図５は第２実施形態における樹脂シート被覆製品２０の断面図である。 (Configuration of resin sheet coated product 20)
The configuration of the resin sheet-covered product 20 in the second embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a perspective view of the resin sheet-covered product 20 in the second embodiment. FIG. 5 is a cross-sectional view of the resin sheet-covered product 20 in the second embodiment.

図４及び図５に示すように、樹脂シート被覆製品２０は、樹脂シート２１によって基材２２を被覆することで構成される。   As shown in FIGS. 4 and 5, the resin sheet-covered product 20 is configured by covering a base material 22 with a resin sheet 21.

樹脂シート２１は、本実施形態においては表面・裏面とも基材２２と嵌合するように形成された模様が形成されたものを用いる。樹脂シート２１の基材２２との対向面２１ａには、接着剤が塗布されている。   In the present embodiment, the resin sheet 21 is formed with a pattern formed so as to be fitted to the base material 22 on both the front surface and the back surface. An adhesive is applied to the surface 21 a of the resin sheet 21 that faces the substrate 22.

基材２２は、樹脂又は金属によって構成される。図５（ａ）に示すように、基材２２の樹脂シート２１との対向面２２ａは、表面加工によって微細な凹凸面となる。微細な凹凸面となることで、樹脂シート２１を張り合わせるときに、樹脂シート２１と基材２２との間に介在する空気を前記微細な凹凸面から外部へ逃がすことができる。これにより、樹脂シート２１と基材２２とを張り合わせたときに、樹脂シート２１と基材２２との間に空気がたまることを防ぎ、樹脂シート被覆製品の表面を、空気だまりや模様のムラがないものにすることができる。   The base material 22 is made of resin or metal. As shown to Fig.5 (a), the opposing surface 22a with the resin sheet 21 of the base material 22 turns into a fine uneven surface by surface processing. By forming the fine uneven surface, the air interposed between the resin sheet 21 and the base material 22 can be released from the fine uneven surface to the outside when the resin sheet 21 is bonded. Thereby, when the resin sheet 21 and the base material 22 are bonded together, air is prevented from accumulating between the resin sheet 21 and the base material 22, and the surface of the resin sheet-coated product is free from air accumulation and pattern unevenness. Can be nothing.

尚、微細な凹凸面は、最大高さＲｙ〔μｍ〕が、１．６≦Ｒｙ≦１００の範囲が好ましい。最大高さＲｙが１．６よりも小さいと空気を外部に逃がすことが困難となり、最大高さＲｙが１００よりも大きいと樹脂シート２１の接着剤の接着性が悪くなる。   The fine uneven surface preferably has a maximum height Ry [μm] in the range of 1.6 ≦ Ry ≦ 100. When the maximum height Ry is smaller than 1.6, it is difficult to let air escape to the outside, and when the maximum height Ry is larger than 100, the adhesiveness of the adhesive of the resin sheet 21 is deteriorated.

また、樹脂シート２１と基材２２とが互いに嵌合するように模様が形成されていることで、真空圧空成形によっても、確実に樹脂シート２１と基材２２とが当接する。これにより、樹脂シート被覆製品２０の表面に立体的な模様を形成することができる。尚、真空圧空成形の方法は、前述の実施形態と同様であるため省略する。   Moreover, since the pattern is formed so that the resin sheet 21 and the base material 22 are fitted to each other, the resin sheet 21 and the base material 22 are surely brought into contact with each other even by vacuum / pressure forming. Thereby, a three-dimensional pattern can be formed on the surface of the resin sheet coated product 20. Note that the vacuum / pressure forming method is the same as that of the above-described embodiment, and therefore will be omitted.
