Title:
METHOD FOR RECYCLING WASTE FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/246320
Kind Code:
A1
Abstract:
The present application provides a method for recycling a waste fiber-reinforced composite material. The recycling method comprises the following steps: (1) subjecting the waste fiber-reinforced composite material to crushing and soaking followed by microwave treatment to obtain a material A; (2) subjecting the material A obtained in step (1) to steam explosion treatment to obtain a material B; and (3) subjecting the material B obtained in step (2) to chemical treatment to obtain a recycled material. The recycling method provided by the present application combines mechanical treatment, microwave treatment, steam explosion treatment, and chemical treatment, and with a specific recycling process, improves the fiber recycling efficiency and realizes the resource recycling of the low-cost fiber composite material, and consumes little energy and has wide application.
