titleOfInvention Method and composition for rubber scrap devulcanization
abstract "METHOD AND COMPOSITION FOR RUBBER WASTE DEVULCANIZATION". The present invention relates to the mechanical and chemical method and composition for rubber devulcanization that maintains macromolecules, restores passive sulfur for further revulcanization, as shown in Fig. 1, is low cost in cost, environmentally friendly and produces High quality replacing virgin rubber. Rubber scraps are torn, ground and metal removed. The modified composition is added when the cut rubber waste particles are poured between two cylinders which then grind the particles. The modified composition is a mixture of a proton donor, an organic acid, friction inhibiting agent. The particles are subjected to at least 10 sets of cylinders.
