<p>PROBLEM TO BE SOLVED: To provide a method for separating other constituting members from a rubber composite body by liquefying a vulcanized rubber composition in a solvent under normal temperature and normal pressure conditions, and also a method for separating a vulcanized rubber composition into a rubber component and a filler component. SOLUTION: A rubber composite body comprising a vulcanized rubber composition and at least one other constituting member is immersed or immersed under agitation in an organic solvent containing 0.01 to 50% of a peroxide so that the ratio of the rubber composite body (mg) to the organic solvent (ml) is 100 or below until the vulcanized rubber composition is liquefied, thereby separating the other constituting member. Likewise, a vulcanized rubber composition comprising a vulcanized rubber and, at least, a filler is immersed or immersed under agitation in a similar organic solvent so that the ratio of the vulcanized rubber composition (mg)/organic solvent (ml) is 30 or below until the vulcanized rubber composition is liquefied, thereby separating the vulcanized rubber composition into a rubber component and a filler component.</p> |
