Recycling of cured phenolic resin

摘要

There is disclosed a method for recycling a cured phenolic resin by (a) heating a cured phenolic resin to form a thermal decomposition product having a residue, (b) separating said residue from said thermal decomposition product, (c) pulverizing said separated residue to obtain a carbide powder and molding said carbide powder alone or in combination with a binder into a molded article, and/or (d) gelling and drying said separated thermal decomposition product thereby molding it into a molded article. By the method, the present invention realizes efficient recycling of a cured phenolic resin which can become a massive waste into a useful material.
