devulcanizing agent for production of reclaim rubber powder
WO2014062043A1 - Devulcanizing agent for production
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 ...

diene rubber in nitrobenzene at 200 C for 3 h [31]. Rooj et al. used benzoyl peroxide as a devulcanizing agent in order to devulcanize sulfur cured natural rubber by chemical and mechano-chemical techniques. Their results showed that selective scission of sulfur crosslinks occurs at low temperature (80 C) and maximum reac-tion time (6 h) [32].
