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.

Next, the above dry blend was melt-kneaded at 250 ° C. using a twin screw extruder (manufactured by Toshiba Machine Co., Ltd., 58 mm ⁇ twin screw extruder) to try to produce a strand. However, since the content of the flaky glass (B) exceeded the upper limit value and a continuous strand of the thermoplastic resin composition could not be obtained, the thermoplastic resin molded product was not evaluated.
- the present invention can provide a thermoplastic resin molded article that is excellent in translucency and reduced in deformation due to temperature change, and uses this thermoplastic resin molded article as a top sheet member for a solar cell module. As a result, a decrease in the maximum output is suppressed, and a lightweight solar cell module can be provided, which is extremely useful industrially.
