Abstract
En 中文
• The DBN/EG enables separation-free upcycling of waste composite insulator cores. • Waste cores are converted into glass fiber-reinforced polyurethane composites. • DBN-activated EG alkoxides selectively cleave ester crosslinks. • Alcoholysis follows a shrinking-core surface erosion model (Ea = 54.97 kJ mol-1). • The organic and inorganic components of the core are utilized at 100% high value.
