N- N- MANUFACTURE METHOD OF N-HETEROCYCLIC CARBENE COMPLEX COMPOUND N-HETEROCYCLIC CARBENE COMPLEX COMPOUND PRODUCED BY THE SAME AND METHOD FOR DELAYING POLYMERIZATION OF POLYURETHANE USING THE SAME

摘要

The present invention relates to a solid N-heterocyclic carbene complex that is a delay catalyst for polyurethane polymerization, and more particularly, to synthesize N-heterocyclic carbene, and to synthesize carbon dioxide ( CO 2 ), zinc (Zn), tin (Sn), and magnesium (Mg) any one adduct selected from the salt (salt) is coordinated to prepare a solid N-heterocyclic carbene complex compound, prepared in this way The N-heterocyclic carbene complex can solve the problem of pot life. Polyurethane polymerization hardly proceeds at room temperature, but when heated to 60° C. or higher, the polyurethane polymerization reaction is initiated, so that the polyurethane polymerization reaction can be effectively carried out by delaying the polymerization of the polyurethane.
