Title:
CROSSLINKING-AGENT MASTERBATCH, RUBBER COMPOSITION CONTAINING CROSSLINKING-AGENT MASTERBATCH, AND CROSSLINKED OBJECT OBTAINED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2023/249096
Kind Code:
A1
Abstract:
There have been problems wherein aromatic polyamines used as crosslinking agents, although bringing about satisfactory scorch stability, not only show poor dispersibility but may deteriorate the working environment because the aromatic polyamines are powdery and prone to fly out. The present invention addresses the problem of providing a method of using an aromatic polyamine, whereby the aromatic polyamine has excellent dispersibility and does not fly out. The problem was found to be solved by producing a masterbatch by dispersing the aromatic polyamine and a lubricant in a synthetic rubber beforehand.
