Description
本発明は、屋外設置用成形体に関する。より詳細には、特定のポリカーボネート樹脂組成物からなる透明性、耐候性、湿熱安定性、防汚性に優れる透明カバーに関する。 The present invention relates to a molded article for outdoor installation. More specifically, the present invention relates to a transparent cover made of a specific polycarbonate resin composition and excellent in transparency, weather resistance, wet heat stability and antifouling property.
近年、太陽光エネルギーの有効利用や、ＬＥＤに代表される照明器具の普及、無線インフラ社会の整備等が進み、これらに関連し屋外に設置されるデバイスがより一層増加している。
これらのデバイスにおいては、ＬＥＤ、有機ＥＬ等の光源を覆う、透明（半透明）の照明カバー、太陽光発電用ソーラーパネルを覆う透明カバー、液晶、計器等を覆う各種メーターカバー等、光の透過性や表示デバイスの視認性が必要とされる為、透明性が必要なカバー部材を有することがある。
このような透明カバー部材には、透明材料が使用されるが、加工が容易であることや、軽量化の観点からガラスよりも熱可塑性樹脂を用いることが望ましい。
In recent years, the effective use of solar energy, the spread of lighting fixtures typified by LEDs, the development of a wireless infrastructure society, etc. have progressed, and the devices installed outdoors are further increasing in relation to these.
In these devices, light transmission such as transparent (semi-transparent) lighting covers covering light sources such as LEDs and organic EL, transparent covers covering solar panels for photovoltaic power generation, various meter covers covering liquid crystal, instruments, etc. And visibility of the display device is required, it may have a cover member that requires transparency.
A transparent material is used for such a transparent cover member, but it is desirable to use a thermoplastic resin rather than glass from the viewpoint of easy processing and weight reduction.
しかしながら、通常使用される熱可塑性樹脂は、屋外環境における様々な環境条件に弱い為、比較的長期間使用することが想定される上記デバイスにおいては耐久性の面で不十分であった。 However, since the thermoplastic resin that is usually used is weak to various environmental conditions in the outdoor environment, it is insufficient in terms of durability in the device that is assumed to be used for a relatively long period of time.
例えば、透明樹脂として最も一般的な、アクリル樹脂は、耐衝撃性が低い為に容易に割れが発生する為、好ましくない。
また、耐熱性が低く、難燃性も低い為、電気電子デバイス用のカバーとしては適さない。
For example, an acrylic resin, which is most common as a transparent resin, is not preferable because cracking easily occurs due to low impact resistance.
Moreover, since heat resistance is low and flame retardancy is low, it is not suitable as a cover for electric and electronic devices.
一方、ポリカーボネート樹脂は、耐衝撃性に優れ、自己消化性も有するが、耐候性、耐湿熱安定性に弱いという致命的な欠点を有していた。 On the other hand, the polycarbonate resin has excellent impact resistance and self-digestibility, but has a fatal defect that it is weak in weather resistance and moist heat resistance.

平均厚みとは、以下のように測定した値の平均値である。
平板の場合は、以下の９点の厚みの平均値とする。
（１）平板の重心点の厚み（１点）、および
（２）重心点を中心に角度４５度の間隔で周辺線（この表現でいいか？）に向かって放射状に直線を８本引き、周辺線との交点と重心とを結ぶ線上の中点の厚み（８点）を測定する。
なお、箱型である場合は、各平板部分で上記（１）（２）と同様の測定を行う。
平板でない場合（例えばレンズのような形状の場合）は、
（３）重心点の厚み（１点）
（４）重心点を中心に角度４５度の間隔で周辺線に向かって放射状に糸や紐のようなフレキシブルな線状物を用いて面上部に沿って線を８本引き、周辺線との交点と重心とを結ぶ線上の中点の厚み（８点）
を測定する。
The average thickness is an average value of values measured as follows.
In the case of a flat plate, the average value of the following nine points of thickness is used.
(1) The thickness of the barycentric point of the flat plate (1 point), and (2) Eight straight lines are drawn radially toward the peripheral line (is this expression OK) with an angle of 45 degrees around the barycentric point, The thickness (8 points) of the midpoint on the line connecting the intersection with the peripheral line and the center of gravity is measured.
In addition, when it is a box type, the same measurement as said (1) (2) is performed in each flat plate part.
If it is not a flat plate (for example, a lens-like shape)
(3) Thickness of the center of gravity (1 point)
(4) Eight lines are drawn along the upper part of the surface using a flexible linear object such as a thread or string radially toward the peripheral line at an angle of 45 degrees around the center of gravity point. The thickness of the midpoint on the line connecting the intersection and the center of gravity (8 points)
Measure.
平均厚みが、０．５ｍｍ未満の場合は、屋外設置用機器の透明カバー材料としては、剛性・耐衝撃性等の機械物性が不十分である他、長期使用によって成形体が濁りやすく視認性が著しく低下する傾向にある為好ましくない。一方、５ｍｍを越える場合は、本発明のポリカーボネートコポリマーが成形加工時に凝集しやすくなり、本発明の屋外設置用透明成形体の著しく透明性が低下する傾向にあるほか、成形体製造時にヒケやソリが発生しやすく、寸法精度にも劣る為やはり好ましくない。このような観点より、平均厚みは、０．７〜４ｍｍがより好ましく、０．８〜３ｍｍがさらに好ましい。 When the average thickness is less than 0.5 mm, the mechanical properties such as rigidity and impact resistance are insufficient as a transparent cover material for outdoor installation equipment. Since it tends to be remarkably lowered, it is not preferable. On the other hand, when the thickness exceeds 5 mm, the polycarbonate copolymer of the present invention tends to aggregate during the molding process, and the transparency of the outdoor-installed transparent molded body of the present invention tends to be remarkably lowered. This is also undesirable because it tends to occur and is inferior in dimensional accuracy.
