(57) [Abstract] [Purpose] Improving the contact efficiency between the resin material and the hydrolyzing agent in the cylinder 1, effectively lowering the molecular weight by hydrolysis of the thermosetting resin, and shortening the regeneration treatment time, To provide a method and a device for recycling a resin waste material, which can contribute to high quality of a recycled resin composition. [Structure] A thermosetting resin-based coating film and a resin waste material containing a thermoplastic resin as a main component are supplied to a passage 1a of a cylinder 1, and while being melted, are supplied from an upstream side to a downstream side by a supply means, and at the same time, a cylinder is used. In the first hydrolysis area 5, the resin material is brought into contact with water or water vapor to hydrolyze the resin material. The seal rings 10, 11 and 13 functioning as resistors are arranged in the passage 1a to suppress the feeding of the resin material in the hydrolysis region 5 to the downstream side to form a high filling region, so that water and water vapor can escape early. And prevent pressure from 10 to 100 kgf / Cm 2 , and the resin temperature is a high temperature of 180 to 280 ° C. |
