Claims7
A process for reclaiming vulcanized rubber comprising the steps of:
- a) impregnating rubber chips obtained from used tire rubber with a composition comprising an essential oil containing a member selected from the group consisting of d-limonene, linalool, mycrene or mixtures thereof;
- b) particulating the treated rubber;
- c) subjecting the rubber particles to microwave heating in the range of 5 KW of output and 2000-3000 MHz of frequency at a reduced pressure whereby substantially all the volatiles are removed and the rubber particles are desulfurized;
- and
- d) recovering the rubber particles.
