In addition, from the viewpoint of cleanliness and non-pollution, it is also required to reduce the environmental load. Furthermore, adhesion with a sealing resin layer and a junction box is also an important required characteristic. In particular, in order to effectively protect the power generation element in the sealing resin layer, adhesion with the sealing resin layer is very important.
- polyphenylene ether is known as engineering plastics with excellent heat resistance, flame retardancy, dimensional stability, non-hygroscopicity, electrical properties, etc., but has difficulty in moldability. Blended with polystyrene with excellent processability. However, blending polystyrene inevitably reduces the flame retardancy of the polyphenylene ether, and therefore this system usually contains a flame retardant.

- Preparation Example 3 Preparation of Resin Composition 3 To 90 parts by mass of PPE resin (supra), 10 parts by mass of a styrene resin (supra) and 7.5 parts by mass of a phosphorus-based flame retardant (supra) are added as a flame retardant.
- the resin composition 3 was prepared by melt-kneading at 300 ° C.
- Preparation Example 4 Preparation of Resin Composition 4 To 90 parts by mass of PPE resin (supra), 10 parts by mass of a styrene resin (supra) and 3 parts by mass of carbon black as a pigment were added, and melt-kneaded at 300 ° C. Resin composition 4 was prepared.
- Preparation Example 5 Preparation of Resin Composition 5 To 90 parts by mass of PPE resin (supra), 10 parts by mass of styrene resin (supra) and 6.5 parts by mass of titanium oxide as a pigment are added, and melt kneaded at 300 ° C. Thus, a resin composition 5 was prepared.
- Preparation Example 6 Preparation of Resin Composition 6 To 90 parts by mass of PPE resin (supra), 10 parts by mass of styrene resin (supra), and 7.5 parts by mass of a phosphorus flame retardant (supra) as a flame retardant and pigment As a result, 6.5 parts by mass of titanium oxide was added and melt-kneaded at 300 ° C. to prepare a resin composition 6.
- Table 1 shows compounding components in the resin compositions 1 to 6 prepared in the above Preparation Examples 1 to 6.
- Examples 1 to 5 and Comparative Examples 1 to 4 As a test lab machine, a 50mm ⁇ , 35mm ⁇ extruder equipped with two kinds of three-layer multilayer T-die was used. A 50 ⁇ m two-type three-layer laminated sheet or a single-layer sheet was formed. Specifically, while carrying out nitrogen purge to the extruder, each raw material is charged, the molten raw material is extruded from a T-die die, cooled and solidified by a cast roll, and the speed of the cast roll is adjusted to be predetermined. A two-type three-layer laminated sheet or a single-layer sheet having a thickness of 50 ⁇ m was formed. The evaluation results for each sheet are shown in Table 2.
- the polyphenylene ether-based laminated film of the present invention is suitable as a solar cell sheet used for protecting a solar cell module.

Abstract
L'invention concerne un film feuilleté qui a, au moins, une couche intermédiaire et des couches de surface sur les deux côtés de celle-ci. Ladite couche intermédiaire comprend une composition de résine (A) qui contient du polyphénylène éther et qui contient également un pigment et/ou un retardateur de flamme. Chacune des couches de surface disposées sur les deux côtés de la couche intermédiaire comprend une composition de résine (B) qui contient du polyphénylène éther et qui ne contient pratiquement pas de pigments ou de retardateurs de flamme.
