VULCANIZATION ACTIVATOR FOR RUBBER MIXES ON BASE OF NON-SATURATED RUBBERS Russian patent published in 2007 - IPC C08L9/00 C08K3/22 C08K5/09 C08K5/3412 C08K5/43 

FIELD: production of tires and mechanical rubber goods; activation of vulcanization of rubber on base of non-saturated rubbers.

SUBSTANCE: rubber vulcanization activator contains the following components, parts by mass: zinc oxide, 5.90-20.0; stearine, 27.40-46.50; ε-caprolactam, 11.60-26.60 and N-(cyclohelxylthio)phthalimide-36. Proposed activator increases rate of vulcanization in main period without reducing the time of beginning of pre-vulcanization - reduction of induction period at retained physical-mechanical parameters of vulcanizers at required level.

EFFECT: enhanced efficiency.
