Description
本発明は、光透過性を有する樹脂組成物に関する。 The present invention relates to a resin composition having light transmission.
例えば遊技機などにおいて、光透過性を有する樹脂組成物を用いた装飾用部材が用いられている。例えば特許文献１には、面発光を行う導光部材を用いて発光させる遊技機の装飾部材が提案されている。この装飾部材は、導光部材の光を反射させる光拡散部材を用いて、発光による演出を行っている。 For example, in a game machine or the like, a decorative member using a resin composition having light transmission is used. For example, Patent Document 1 proposes a decorative member for a gaming machine that emits light by using a light guide member that emits light from a surface. This decorative member uses a light diffusing member that reflects the light of the light guide member to produce light emission.
特許文献１の導光部材は、ライトから光を導入して拡散することにより、広い範囲において発光しているように見せる部材である。このような面発光用の部材は、従来、大きな発光量を実現するために光拡散剤を多量に含有させていた。そのため、その部材の透過性は低下してしまい、特許文献１のように遊技者には直接には視認されない場所に配置されて用いられるか、或いは、透過性が低く、その内側を外部からは視認できない状態のものとして用いられていた。すなわち、透過性が低いことにより用途や装飾のアイデアが限定されていた。 The light guide member of Patent Document 1 is a member that makes it appear as emitting light in a wide range by introducing light from a light and diffusing it. Conventionally, such a member for surface light emission contains a large amount of a light diffusing agent in order to realize a large amount of light emission. Therefore, the transparency of the member is lowered, and the member is placed and used in a place that is not directly visible to the player as in Patent Document 1, or the transparency is low and the inside thereof is viewed from the outside. It was used as something that could not be seen. That is, the low transparency limits the use and decoration ideas.
本発明の目的は、透過性が高く、かつ、高度な拡散性を有する樹脂組成物を提案することである。 An object of the present invention is to propose a resin composition having high permeability and high diffusivity.
本発明の一態様は、白色顔料と、光拡散剤と、ポリカーボネートと、を含み、光透過性を有する樹脂組成物である。このような樹脂組成物は、明確な理由は必ずしも明らかではないが、光の拡散効果を高度に上昇させることができる。よって、光拡散剤の配合量の削減が可能となり、透過性を高く維持しつつ光の拡散効果を高めて、明るく発光させることができる。 One aspect of the present invention is a resin composition containing a white pigment, a light diffusing agent, and polycarbonate, which has light transmittance. Such a resin composition can highly enhance the light diffusing effect, although the clear reason is not always clear. Therefore, it is possible to reduce the blending amount of the light diffusing agent, enhance the light diffusing effect while maintaining high transparency, and make the light emit brightly.
上述した樹脂組成物において、白色顔料として、少なくとも酸化チタンを含んでいてもよい。酸化チタンを用いることで、光の拡散効果をより高めることができる。なお、酸化チタンが樹脂組成物に０．００００５～０．０１質量％の範囲で含まれると、樹脂組成物の透明性を高度に維持しつつ発光機能を発揮することができる。 In the above-mentioned resin composition, at least titanium oxide may be contained as the white pigment. By using titanium oxide, the light diffusion effect can be further enhanced. When titanium oxide is contained in the resin composition in the range of 0.00005 to 0.01% by mass, the light emitting function can be exhibited while maintaining a high degree of transparency of the resin composition.
上述した樹脂組成物において、光拡散剤は、無機系光拡散剤、アクリル系光拡散剤、シリコン系光拡散剤、のうちの少なくともいずれか１つを含んでいてもよい。このような光拡散剤であれば、光の拡散効果をより高めることができる。なお、シリコン系光拡散剤が樹脂組成物に０．０００５～０．１質量％の範囲で含まれると、樹脂組成物の透明性を維持しつつ発光機能を高めることができる。 In the resin composition described above, the light diffusing agent may contain at least one of an inorganic light diffusing agent, an acrylic light diffusing agent, and a silicon light diffusing agent. With such a light diffusing agent, the light diffusing effect can be further enhanced. When the silicon-based light diffusing agent is contained in the resin composition in the range of 0.0005 to 0.1% by mass, the light emitting function can be enhanced while maintaining the transparency of the resin composition.
上述した樹脂組成物は、少なくとも一部が、一定の肉厚であって、平面形状及び曲面形状のうちの少なくともいずれか一方の形状に形成され、光の透過性を有する透光部と、透光部に向かう光を導入する光導入面と、を備えていてもよい。 The above-mentioned resin composition has at least a part having a constant wall thickness, is formed in at least one of a planar shape and a curved surface shape, and has a light-transmitting portion and a light-transmitting portion. It may be provided with a light introduction surface for introducing light toward the light unit.
このように構成された樹脂組成物であれば、光導入面から導入された光の透光部による拡散を良好に実現することができる。 With the resin composition configured in this way, diffusion of light introduced from the light introduction surface by the translucent portion can be satisfactorily realized.
以下に本発明の実施形態を図面と共に説明する。なお以下の実施形態は本発明の一形態に過ぎず、本発明は以下の実施形態に何ら限定されることはなく、本発明の技術的範囲に属する限り種々の形態をとり得ることはいうまでもない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１Ａ，Ｂに、樹脂組成物の形状の例を示す。
樹脂組成物１は、半球形状であって薄板状の曲面部３と、曲面部３の外周の端部に設けられるフランジ状のフランジ部５と、を備える。フランジ部５における曲面部３と接続する側とは反対側の面５ａからＬＥＤなどの発光部材１１により光を導入すると、曲面部３の全体において光を拡散し、発光したような状態となる。曲面部３が本発明の透光部に相当し、面５ａが本発明の光導入面に相当する。
FIGS. 1A and 1B show an example of the shape of the resin composition.
The resin composition 1 includes a hemispherical and thin plate-shaped
［３．効果］
（３ａ）上記実施例にて製造した樹脂組成物は、高い透明度を示すものである。そして、同様の透明度を示す従来の材料、例えばアクリル樹脂又はＡＢＳ樹脂の基材に光拡散剤を配合したものと比較して、光を導入したときに、より明るく発光（面発光）する。すなわち、上述した樹脂組成物は、透過性と、高度な光拡散性と、を両立することができる。
[3. effect]
(3a) The resin composition produced in the above example exhibits high transparency. Then, when light is introduced, it emits light brighter (surface emission) as compared with a conventional material exhibiting the same transparency, for example, an acrylic resin or an ABS resin base material in which a light diffusing agent is blended. That is, the above-mentioned resin composition can achieve both transparency and high light diffusivity.
白色顔料と光拡散剤とを同時に含むことにより、光が樹脂組成物内に導入されたときの反射性が高度に高まる理由は必ずしも明らかではないが、その効果によって光拡散剤の使用量を低減でき、透過性を高めることができる。 It is not always clear why the simultaneous inclusion of the white pigment and the light diffusing agent greatly enhances the reflectivity when light is introduced into the resin composition, but the effect reduces the amount of the light diffusing agent used. It can be done and the transparency can be increased.
（３ｂ）特に、白色顔料として酸化チタンを用い、光拡散剤としてシリコン系光拡散剤を用いることで、より高度な透過性と光拡散性を両立することができる。
（３ｃ）樹脂組成物はポリカーボネートを主剤として構成されているため、頑丈であり、破損がし難く都合がよい。
(3b) In particular, by using titanium oxide as the white pigment and a silicon-based light diffusing agent as the light diffusing agent, it is possible to achieve both higher transparency and light diffusing property.
(3c) Since the resin composition is composed mainly of polycarbonate, it is sturdy and is not easily damaged, which is convenient.

If it is desired to further increase the transparency, the blending ratio of the white pigment or the light diffusing agent may be reduced. On the contrary, if it is desired to further enhance the light emitting property, the blending ratio of the white pigment or the light diffusing agent may be increased.

High luminescence (diffusivity) can be realized, and higher transparency can be realized when it is 0.005% by mass or less, particularly 0.001% by mass or less.
