Embodiment 1
[0095] A coating solution obtained by adding 1 part by weight of butanol to 1 part by weight of carbon black having an average particle diameter of 300 nm was applied to both sides of an aluminum foil having a thickness of 50 μm and a composition shown in Table 1 below. Next, this was dried at a temperature of 100° C. for 10 minutes, thereby forming a coating layer. The formation of the coating layer at this time was adjusted so that the thickness of the coating layer after drying was 1 μm on one side.
[0096] Then, the aluminum foil on which the covering layer was formed was cut into a size of 10 mm in width and 100 mm in length to prepare two samples. The obtained two samples were held at a temperature of 600° C. for 10 hours in a methane gas atmosphere in a state where the respective ends of the 10 mm×10 mm portions were overlapped and contacted, thereby producing an evaluation sample.
Embodiment 2、3
[0098] Except having used the aluminum foil of the composition shown in Table 1, it carried out similarly to Example 1, and produced the evaluation sample.
Embodiment 4
[0100] It is 50 μm in thickness, double-sided coating of the aluminum foil of the composition shown in following Table 1 is that 2 weight parts of the titanium dioxide particle that average particle size is 10nm has added the polyvinyl butyral resin of 1 weight part, 7 weight parts Toluene: Methyl ethyl ketone = 1:1 mixed solution of the coating liquid. Next, this was dried at a temperature of 100° C. for 10 minutes, thereby forming a coating layer. The formation of the coating layer at this time was adjusted so that the thickness of the coating layer after drying was 1 μm on one side.
[0101] Then, the aluminum foil on which the covering layer was formed was cut into a size of 10 mm in width and 100 mm in length to prepare two samples. The obtained two samples were held at a temperature of 600° C. for 10 hours in a methane gas atmosphere in a state where the respective ends of the 10 mm×10 mm portion were overlapped and contacted, thereby producing an evaluation sample.
