Self-Healing Sealing Composite for High-Temperature Equipment

The patent uses composite materials by combining high molecular elastomer with reactive functional groups (amines and carboxylic acids) that form cross-linked networks through hydrogen bonding and covalent bonds. This composite structure provides both the elastic properties needed for sealing and the thermal stability for extended service life at high temperatures.

The patent changes the chemical parameters of the elastomer by introducing functional groups that can undergo chemical reactions. The amine and carboxylic acid groups react to form cross-linked structures, transforming the material from a simple elastomer to a chemically modified composite that resists high-temperature degradation.

The patent applies preliminary action by pre-installing the self-healing functional groups into the sealing ring material before it is put into service. These functional groups are prepared in advance to automatically activate and repair damage when high-temperature conditions trigger the healing response, preventing production disruptions.

The patent implements self-service through the autonomous self-healing capability of the sealing ring. The embedded amine and carboxylic acid groups automatically detect and repair thermal damage without external intervention, allowing the seal to maintain effectiveness and prevent production interruptions.
