Technical Field
The invention relates to the technical field of sealing element materials, in particular to a ceramic rubber sealing material.
Background
Seals have found widespread use in industry, and the direct consequence of seal failure is leakage of the sealing fluid. In the industrial production process, the aging, embrittlement, melting and the like of the sealing member are accelerated when the temperature of the use environment is not consistent with that of the sealing member or when the sealing member is in a heat overload state, mainly because the rubber sealing member is softened or even melted when the temperature is increased. In the prior art, organic additives are mostly adopted to block the open loop movement of macromolecular chains in the sealing element material, so that the exploration and excavation of a high-temperature-resistant sealing element material to solve the problem of short service life of the sealing element under the high-temperature condition are very important. The ceramic has the characteristics of high-temperature wear resistance, corrosion resistance, high strength, high toughness and good sealing property of a rubber material, is integrally designed, and is convenient to replace and install.
