表面に塗布する方法などが知られている。[Conventional technology] Conventionally, a method of imparting appropriate conductivity to the surface of highly insulating rubber materials for the purpose of preventing static electricity and preventing static electricity damage was to add conductive fillers such as carbon black or metal powder to rubber.

なり、異物の量が多くなるとゴム材料本来のもつ優れた
弾力性が低下してしまうという問題がある。[Problems to be Solved by the Invention] However, although only the surface of the rubber material is required to be conductive, the conventional method of kneading conductive fillers and surfactants does not make the entire rubber material conductive. In addition to the drawback that the rubber material itself contains foreign matter, there is a problem that as the amount of foreign matter increases, the excellent elasticity inherent to the rubber material decreases.
一方、界面活性剤をゴム材料の表面に塗布する方法は、

結合することができ、かつ適度の導電性を有する材料を
ゴム材料の表面のみに形成させることが必要である。Therefore, in order to impart appropriate conductivity only to the surface without impairing the original properties of the rubber material, a material that can be strongly bonded to the rubber material and has appropriate conductivity is added to the surface of the rubber material. It is necessary to form only

添加すればよい。Note that low-temperature plasma treatment greatly reduces the surface friction coefficient, but if you want to reduce the surface electrical resistance without reducing the surface friction coefficient, use silica, talc, clay, etc. for the rubber material to be subjected to low-temperature plasma treatment. An inorganic filler may be added.
