Abstract
PURPOSE: To reduce the friction resistance of a rubber material containing Si by covering it with a metal fluoride to prevent the chalking of the material due to a fluorine gas before the surface treatment retaining it in the gas.
CONSTITUTION: A rubber material containing Si (for example, a rubber blended with an Si containing compound such as silica or a silicon rubber) is covered with a metal fluoride such as sodium fluoride and then, retained in a fluorine gas for surface treatment. There is a tendency that the fluorine gas reacts hydrogen in the rubber material to form hydrogen fluoride which will cause the chalking of the rubber by corroding an Si compound. But the metal fluoride absorbs hydrogen fluoride non-reversibly thereby preventing the chalking of the rubber material positively. It is ideal for the treatment of reducing the friction resistance of the surface of an oil seal or the like.
