[0066] The formulations of the formulation ratios shown in Table 1 were melt-kneaded using a 5-liter intensive mixer (Nippon Roll MFG) Co., Ltd. (Nippon Roll MFG). At this time, the discharge temperature was set at 190°C. Then, using the roll diameter of Nippon Roll Manufacturing Co., Ltd., the roll diameter is 200mm, the roll width is 700mm reverse L word four roll calenders, and the film that obtains thickness is 300 μm (roll temperature according to the first roll / second roll / third roll) The sequence of rolls / fourth roll was 205°C / 205°C / 185°C / 175°C, the stretching speed was 5 m / min). For the obtained film, the volume resistivity ρ and the tensile elongation E were determined, and tests for bending resistance and flexibility were performed according to the following methods. The results are shown in Table 1.

Abstract

The present invention provides a resin composition used as a conductive resin that is excellent in conductivity, tensile elongation, bending resistance, and flexibility, and is suitable for electrodes or electrode coating protection in redox flow batteries and the like membrane. The resin composition of the present invention comprises: 100 parts by mass of (A) thermoplastic resin, 1 to 60 parts by mass of (B) carbon nanotubes, and 1 to 100 parts by mass of (C) selected from acetylene black and At least one of the group consisting of graphite.

Description

technical field [0001] The present invention relates to a resin composition used for a conductive resin film, and more specifically, to a resin composition used for a conductive resin film excellent in tensile elongation, bending resistance, or flexibility. Background technique [0002] In recent years, so-called renewable energy such as solar power generation, wind power generation, and wave power generation has attracted attention as a new energy source that can replace fossil fuels such as petroleum or atomic power. However, since these renewable energies are strongly affected by weather and the like, the output is extremely unstable. Therefore, in order to connect a large amount of these energies to the power grid, for example, it is necessary to install a large-capacity storage battery in parallel to stabilize output fluctuations and the like. [0003] One of large-capacity storage batteries is a redox flow cell. A redox flow battery is a battery that separates two ki...
