Patent

CA 2308162

The invention relates to the high temperature mixing of elastomeric material in the presence of a quinone diimime antidegradant and carbon black, prior to vulcanization. By mixing the antidegradant quinone diimine with the elastomer prior to vulcanization, enhanced handling and processing qualities are realized in the vulcanized rubber.

L'invention concerne le mélange à haute température et avant la vulcanisation de matière élastomère en présence d'un agent protecteur sous forme de quinone diimine et de noir de carbone. En mélangeant l'agent protecteur quinone diimine avec l'élastomère avant la vulcanisation, on obtient un caoutchouc vulcanisé présentant des qualités de manipulation et de traitement améliorées.
