<p><P>PROBLEM TO BE SOLVED: To solve a problem, in a manufacturing method of a resin-based modifier comprising burning a synthetic resin waste material in an oxygen-deficient state to cause a part of the rest of the synthetic resin waste material to melt or pyrolyze by the combustion heat to obtain the resin-based modifier, that combustion residue accumulates on the rooster with the lapse of combustion time and the other raw materials are buried in the combustion residue resulting in discontinuation of the combustion of the raw materials and a problem that the resin modifier cannot be efficiently manufactured because the formed wax-like melt mixes with the combustion residue to cause deterioration in qualities of the resin-based modifier and because the formed wax-like melt is absorbed in the combustion residue or absorbed and further disappears. <P>SOLUTION: The synthetic resin waste material is molten or pyrolyzed with its longitudinal direction maintained perpendicular. Thus, the molten wax-like melt is separated in the cross section to permit efficient manufacture of the resin-based modifier of good qualities. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
