DEVULCANIZING AGENT FOR PRODUCTION OF RECLAIM RUBBER POWDER

摘要

The present invention relates to a chemical composition of the devulcanizing agent which is used to reclaim waste rubber by mechanical shearing until fine powder is produced. The devulcanizing agent contains two types of components: 1) amino acids amides or similar carbonyl and amine or amide group containing organic compounds as Reactants for derealization of sulfur crosslinks and 2) ashless inorganic salts as Anti Stick additives for subsequent size reduction of rubber particles and preventing them from sticking. In a form of powder the reclaim rubber shows much better technical properties than in a form of sheet bale or other bulk solid.
