Abstract:
1. A system for producing a raw material for a recycled resin composition, comprising: a decomposition reaction apparatus comprising, a main reaction body, comprised of: an introduction section for introducing a resin composition containing a thermosetting resin and a solvent containing a monomer component of the thermosetting resin or a derivative of the monomer component; a decomposition reaction section for obtaining a first treated recovery product containing a recycled resin formed of the thermosetting resin with a reduced molecular weight, a solid residue and a low-boiling-point component containing the solvent, by heating and pressurizing the resin composition and the solvent and bringing the solvent into a supercritical state or a subcritical state; a discharge section for discharging the first treated recovery product, a supply unit for continuously supplying the resin composition and the solvent as a mixture to the introduction section, wherein the supply unit compromises a pressurizing device for pressurizing and supplying the resin composition and the solvent as a mixture to the introduction section; wherein introduction of the resin composition and the solvent into the introduction section, decomposition treatment of the thermosetting resin in the decomposition reaction section and discharge of the first treated recovery product from the discharge section are all performed continuously, a polymerization reaction apparatus for obtaining a second treated recovery product containing the low-boiling-point component, the solid residue and a recycled resin with an increased molecular weight obtained by introducing and polymerizing a multifunctional compound and the recycled resin with the reduced molecular weight contained in the first treated recovery product, a first separating unit for separating and removing the solid residue from the second treated recovery product, and a second separating unit for separating and extracting the recycled resin with the increased molecular weight as well as the low-boiling-point component from the second treated recovery product from which the solid residue has been removed, wherein the polymerization apparatus, the first separating unit and the second separating unit are connected to the discharge section of the decomposition reaction apparatus in the named sequence.
