CHEMICALLY DISSOLVABLE THERMOSETTING RESIN COMPOSITION FOR RECYCLING OF FIBER-REINFORECED COMPOSITE AND DISSOLUTION METHOD THEREOF

摘要

The present invention relates to a chemically decomposable thermosetting resin composition for recycling fiber-reinforced composites and a dissolution method thereof. Epoxy resin according to the present invention; Polyfunctional glycidyl ester-based compounds; At least one of the ends of the main chain is an additive having a hydroxyl group; And an acid anhydride curing agent, the chemically decomposable thermosetting resin composition has excellent chemical decomposition performance in a basic solution and has a high glass transition temperature, so that the thermosetting composite material comprising the thermosetting resin according to the present invention is hydrolyzed. Recycling of carbon fiber is possible, and thus there is an advantage that the industry of recycling of carbon fiber and the industry of recycling resin can be newly expanded, and the thermosetting resin can be applied not only to carbon composite materials, but also to fields where general thermosetting resins are used. , Because it can be hydrolyzed in a basic solution, it can drastically reduce the cost of landfill or disposal.
