METHOD AND APPARATUS FOR DECOMPOSING AND RECYCLING THERMOSETTING RESIN COMPOSITE MATERIAL AND COMPOSITION UTILIZED THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/114587
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for decomposing and recycling a thermosetting resin composite material and a composition and kit utilized therefor, wherein the method comprises the steps of pretreating a thermosetting resin composite material in an aqueous formic acid solution or an aqueous hydrogen peroxide solution; and subjecting the pretreated thermosetting resin composite material to main treatment in a hydrogen peroxide solution or an aqueous formic acid solution, the aqueous solutions used in the pretreatment and the main treatment being different from each other. Unlike conventional chemical decomposition methods, the method according to the present invention can remarkably reduce decomposition time even in the condition of a low temperature and atmospheric pressure, can solve the problem that it is difficult to establish mass production facilities due to the odor (stink) of chemical solutions and the corrosion of the materials, and can maintain reaction performance even at reduced concentrations of the chemical solutions, allowing a great increase in the use number of the solutions. Accordingly, the production cost can be exceptionally reduced.
