PROCESS FOR TREATING DREGS, TREATED DREGS, USE THEREOF, PROCESS FOR VULCANIZING RUBBER, AND VULCANIZED RUBBER

摘要

The invention refers to a process for treating dregs for the application thereof as vulcanization activator of rubbers, putting an end to this residue generated in the cellulose industry and providing vulcanized rubbers with similar or enhanced properties in relation to those already known. The simple process for treating dregs comprises the steps of: (a) drying the dregs; and (b) micronization of the dry dregs to an average particle size (d50) from 2 to 45 micrometers. The invention also refers to treated dregs, to the use of treated dregs as vulcanization activator, and to a process for vulcanizing rubber and to the vulcanized rubber.
