VULCANIZED RUBBER SEPARATION AND RECOVERY METHOD

Title:

VULCANIZED RUBBER SEPARATION AND RECOVERY METHOD

Document Type and Number:

WIPO Patent Application WO/2011/093104

Kind Code:

A1

Abstract:

Provided is a vulcanized rubber separation and recovery method which not only has a low reaction temperature and a high energy efficiency, but also exhibits excellent reaction speed and properties for recycling and recovering the separation reaction product. The vulcanized rubber separation and recovery method uses a bivalent iron ion as the reaction initiator, and involves: separating a vulcanized rubber containing a filler by means of the lipid peroxidation reaction of linoleic acid; dissolving the separated rubber component in an organic solvent; removing the lipids by reprecipitating the rubber component in alcohol added with alkali; and recovering the rubber portion.
