METHOD FOR TREATING PLASTIC, RECYCLING METHOD, TREATED AND RECOVERED MATERIAL AND RECYCLED PLASTIC

摘要

PPROBLEM TO BE SOLVED: To provide a method for treating a plastic in which decomposition and/or solubilizing efficiency is improved and a treated and recovered material having characteristics suitable for recycle can be obtained and a recycling method and to provide a treated and recovered material and a recycled plastic. PSOLUTION: The method for treating a plastic comprises carrying out solubilizing treatment of a plastic by specifying the range of the viscosity obtained by constant shear rate measurement with a conical plate rotational viscometer at 230.2C of a slurry essentially composed of a plastic including a thermosetting resin and a solvent essentially composed of a phenol compound. The treated and recovered material is obtained by treating a plastic by the treating method. The recycling method of a plastic comprises recycling the treated and recovered material as a raw material of a plastic. The recycled plastic is obtained by recycling the treated and recovered material as a raw material. PCOPYRIGHT: (C)2006,JPO&NCIPI
