Method for promoting chemical bonding between elastomer and carbon black using benzene sulfonyl azides derivatives.

摘要

Method for promoting chemical bonding between elastomer and carbon black using benzene sulfonyl azides derivatives. The reinforcing power of carbon black depends on the nature and density of the surface interactions between the particle and the polymer matrix. High resistance interactions are the most important to improve the response of a reinforcing carbon black. There are chemicals that act as "promoters" or "coupling agents', which added to an elastomer / black carbon mixture, before or during mastication of rubber, improve the reinforcing of the load, resulting in vulcanized properties physical higher. By derivatives benzenesulfonyl azide is improved resistance interactions in Internase load-elastomer.
