Self-healing elastomer system

摘要

The self-healing elastomer system comprises an elastomer (6), which has a surface, an interior and an elastomer matrix, a liquid phase (3), which limits at the surface of the elastomer and contains an additive (4), and catalyst, reaction accelerator and/or reaction initiator. The elastomer matrix has covalently bonded first functional group in the interior. The first functional group and the additive are selected, so that the functional group, which contacts with the liquid phase, makes a reaction in the case of damage of the elastomer. The elastomer is stabilized by the reaction. The self-healing elastomer system comprises an elastomer (6), which has a surface, an interior and an elastomer matrix, a liquid phase (3), which limits at the surface of the elastomer and contains an additive (4), and catalyst, reaction accelerator and/or reaction initiator. The elastomer matrix has covalently bonded first functional group in the interior. The first functional group and the additive are selected, so that the functional group, which contacts with the liquid phase, makes a reaction in the case of damage of the elastomer. The elastomer is stabilized by the reaction. The system contains second functional groups, which react with the first functional groups, are constituents of the elastomer matrix or constituents of the additives, and are non-covalently embedded in the matrix. The additive has second functional groups. The reaction of the first functional groups of the elastomer matrix takes place with the second functional groups of the additives, and takes place among one another. The second functional groups are covalently bonded with the elastomer matrix. Coagents are contained in the elastomer matrix, are non-covalently bonded with the matrix and have second functional group. The reaction of the first functional groups of the elastomer matrix takes place with the second functional groups of the coagents. The reaction is the formation of covalent bonds or the formation of non-covalent interaction such as van der Waals, magnetic, electrostatic, ionic, hydrophobic, dipolar and other interactions, and is a cross-linking reaction. The additive consists of particles, which contain second functional groups at the surface. The functional groups and the additive are magnetic and/or ionic and have an affinity to each other. The elastomer has a separating layer (2), which is arranged between the elastomer matrix and the liquid phase. Independent claims are included for: (1) a self-healing elastomer; and (2) a method for producing a self-healing elastomer system or for healing damages of elastomers.
