Recycling of Waste Tire Rubber Using Devulcanizing Agents and Virgin Polymer by Ionizing Radiation

Abstract

Ground tire rubber (GRT) poses an interesting environmental, economical, and removal problem in the world because of their crosslinked three-dimensional network structure. Rubber devulcanization is a process in which the row rubber or vulcanized waste product is changed, using mechanical, thermal, or chemical energy, into the state in which it can be mixed, processed, and vulcanized again. In mechanochemical devulcanization of rubber that maintains the macromolecules of waste rubber, reduces the sulfur passive for later revulcanization, is cost effective, environmentally friendly and yields high quality devulcanized rubber to substitute virgin rubber.
