Problems solved by technology

However, in these methods, when the flame retardancy is improved, there is a problem that the wear resistance, strength, and pressure contact characteristics are significantly reduced.
In addition, when crosslinking, there is a problem that resources cannot be recycled
[0012] In addition, when a large amount of metal hydrate is added, the oil resistance will be significantly reduced, and it cannot be used in parts that require oil

Embodiment

[0135] Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited thereto.

[0136] Magnesium hydroxide (1)~(5)

[0137] Magnesium hydroxide (1)-(5) was produced by the following method.

[0138] Add 400 ml of magnesium chloride aqueous solution (Wako Pure Chemical Industries, Ltd.) adjusted to a concentration of 0.5 mol / L in the autoclave and boric acid (manufactured by BORAX) in an appropriate amount within the range of 0.01 to 150 mol % relative to magnesium chloride, and stir 121 ml of 3N caustic soda solution was added dropwise and reacted at room temperature (25° C.) for 30 minutes to obtain a magnesium hydroxide particle suspension.

[0139] The suspension was hydrothermally treated at 180°C for 2 hours, dehydrated, washed with water (200 ml), and dried at 105°C for 24 hours to obtain magnesium hydroxide having a predetermined aspect ratio and BET specific surface area. The obtained magnesium hydroxi...
