Definitions
- the present invention relates to a thermoplastic resin composition, a thermoplastic resin molded body, a thermoplastic resin laminated molded body, and a solar cell module.
- This application claims priority based on Japanese Patent Application No. 2012-152115 for which it applied to Japan on July 6, 2012, and uses the content here.
- a glass material has been used for a top sheet member of a solar cell module.
- the glass topsheet member has good dimensional stability and flame retardancy, but it is necessary to use chemically tempered glass to reduce the thickness for weight reduction, which is large like a solar cell module.
- the cost is high.
- replacement with a resin material has been studied in order to reduce the weight of the solar cell module.
- a resin material having good translucency is required in order to improve the photoelectric conversion efficiency of the solar cell.
- Patent Document 1 proposes a sheet in which glass having a refractive index difference of 0.01 to 0.04 with a transparent resin is dispersed in a transparent resin as a glass substitute resin sheet.
- the glass used is fibrous and has a small fiber diameter, multiple scattering is likely to occur in the resulting molded body, and the translucency may be reduced.
- flaky glass discloses that the flaky glass is dispersed in an amount of 0.1 to 20% by weight in a thermoplastic resin. There has been proposed a molded body obtained by the above process.
- the present invention has been made in view of the above circumstances, and is a heat capable of providing a top sheet member for a solar cell module that is excellent in translucency and that suppresses a decrease in the maximum output of the solar cell module even after a thermal cycle test. It is an object of the present invention to provide a thermoplastic resin composition, a thermoplastic resin molded body and a thermoplastic resin laminate molded body that can be used as a top sheet member for a solar cell module, and a solar cell module having the above performance.
- thermoplastic resin composition comprising a thermoplastic resin (A) and flaky glass (B),
- the aspect ratio of the flaky glass (B) in the thermoplastic resin composition is 30 to 80,
- the content of the flaky glass (B) in the thermoplastic resin composition is 25 to 70 parts by mass with respect to 100 parts by mass of the thermoplastic resin (A).
- thermoplastic resin composition in which a difference between a refractive index of the thermoplastic resin (A) and a refractive index of the flaky glass (B) in the thermoplastic resin composition is 0 or more and 0.05 or less.
- thermoplastic resin molded article containing the thermoplastic resin (A) and the flaky glass (B),
- the aspect ratio of the flaky glass (B) in the thermoplastic resin molded body is 25 to 70
- the content of the flaky glass (B) in the thermoplastic resin molded body is 25 to 70 parts by mass with respect to 100 parts by mass of the thermoplastic resin (A).
- the difference between the refractive index of the thermoplastic resin (A) in the thermoplastic resin molded body and the refractive index of the flaky glass (B) is from 0 to 0.05
- a thermoplastic resin molded article having a total light transmittance of 86% to 93% in the thermoplastic resin molded article is from 0 to 0.05
- the melt flow rate of the thermoplastic resin (A) in the thermoplastic resin molded body is 5 g / 10 min or more and 20 g / 10 min or less, according to any one of the above [5] to [7] Thermoplastic resin molding.
- thermoplastic resin molded article according to any one of [5] to [8], wherein the thermoplastic resin (A) is a (meth) acrylic resin or a polycarbonate resin.
- thermoplastic resin laminated molded article in which a (meth) acrylic polymer protective layer is laminated on the thermoplastic resin molded article according to any one of [5] to [9].
- the thermoplastic resin laminate molded article according to [10] comprising at least one component selected from the group consisting of products.
- thermoplastic resin molded article according to any one of [6] to [9] or the thermoplastic resin laminate molded article according to [10] or [11] .
- thermoplastic resin molded body or the thermoplastic resin laminated molded body is a sheet having a thickness of 1 to 3 mm.
- thermoplastic resin molded article that is excellent in translucency and reduced in deformation due to temperature change.
- thermoplastic resin molded body as a top sheet member for a solar cell module, it is possible to provide a lightweight solar cell module in which a decrease in maximum output is suppressed.

This application claims priority based on Japanese Patent Application No. 2012-152115 for which it applied to Japan on July 6, 2012, and uses the content here.
従来、太陽電池モジュールのトップシート部材にはガラス材料が用いられている。ガラス製のトップシート部材は寸法安定性及び難燃性が良好であるが、軽量化のために厚みを薄くするためには化学強化ガラス等を使用する必要があり、太陽電池モジュールのような大面積の製品に使用する場合には高コストとなる。このため、太陽電池モジュールの軽量化のために樹脂材料への置き換えが検討されている。
太陽電池モジュールのトップシート部材として樹脂材料を使用する場合、太陽電池の光電変換効率を良好とするために、良好な透光性を有する樹脂材料が求められる。
透光性に優れた樹脂材料を得る方法としては、透明なマトリクス樹脂中に透明な粒子や繊維等を分散させ、マトリクス樹脂と粒子の屈折率差を調整する方法が知られている。
例えば、特許文献１には、ガラス代替樹脂シートとして、透明樹脂中に透明樹脂との屈折率差が０．０１～０．０４であるガラスを分散させたシートが提案されている。しかしながら、用いられているガラスは繊維状で、且つ、繊維直径が小さいため、得られる成形体内で多重散乱が生じ易く、透光性が低下する恐れがある。
上記の繊維状ガラスの問題点を解決するために、例えば、フレーク状ガラスを使用することが考えられ、特許文献２には、熱可塑性樹脂中にフレーク状ガラスを０．１～２０重量％分散させて得られる成形体が提案されている。 Conventionally, a glass material has been used for a top sheet member of a solar cell module. The glass topsheet member has good dimensional stability and flame retardancy, but it is necessary to use chemically tempered glass to reduce the thickness for weight reduction, which is large like a solar cell module. When used for a product with an area, the cost is high. For this reason, replacement with a resin material has been studied in order to reduce the weight of the solar cell module.
When using a resin material as a top sheet member of a solar cell module, a resin material having good translucency is required in order to improve the photoelectric conversion efficiency of the solar cell.
As a method for obtaining a resin material having excellent translucency, a method is known in which transparent particles, fibers, and the like are dispersed in a transparent matrix resin to adjust the refractive index difference between the matrix resin and the particles.
For example, Patent Document 1 proposes a sheet in which glass having a refractive index difference of 0.01 to 0.04 with a transparent resin is dispersed in a transparent resin as a glass substitute resin sheet. However, since the glass used is fibrous and has a small fiber diameter, multiple scattering is likely to occur in the resulting molded body, and the translucency may be reduced.
In order to solve the problems of the above-mentioned fibrous glass, for example, it is conceivable to use flaky glass. Patent Document 2 discloses that the flaky glass is dispersed in an amount of 0.1 to 20% by weight in a thermoplastic resin. There has been proposed a molded body obtained by the above process.

一方、太陽電池モジュールには高い信頼性が必要であり、この要求を満たすために、８５℃～－４０℃の温度変化が生じる熱サイクル試験に対しても変形が少ないトップシート部材が求められる。
このような状況において、特許文献２に示される成形体ではガラスの含有率が低いため、熱サイクル試験後に太陽電池モジュールの最大出力が低下するという問題がある。 On the other hand, high reliability is required for the solar cell module, and in order to satisfy this requirement, a top sheet member with less deformation is required even for a thermal cycle test in which a temperature change of 85 ° C. to −40 ° C. occurs.
In such a situation, the molded body disclosed in Patent Document 2 has a problem that the maximum output of the solar cell module decreases after the thermal cycle test because the glass content is low.
