Description

technical field

[0001] The invention relates to the field of seals, in particular to an oil-resistant, high-temperature, oxidation-resistant seal and a preparation method thereof. Background technique

[0002] The sealing ring is an annular cover composed of one or several parts, which is fixed on a ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap. It is the most widely used in hydraulic and pneumatic transmission systems One, it can prevent the leakage of lubricating oil and the intrusion of foreign objects. At present, the commonly used materials for sealing rings are: nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc. When selecting the material for the sealing ring, the compatibility of the material to the working medium and the adaptability to the working temperature range must be considered.

[0003] At present, the sealing rings on the market use ordinary...
