| titleOfInvention | A kind of composite modified 2-methylimidazole curing agent and preparation method thereof |
| abstract | The invention discloses a composite modified 2-methylimidazole curing agent and a preparation method thereof, belonging to the field of fine chemicals. The preparation process of the composite modified curing agent is as follows: firstly, an intermediate product is prepared by reacting 2-methylimidazole and organic carbonate, and then the intermediate product is reacted with a metal salt to obtain a viscous liquid composite modified 2-methyl ester at room temperature. Imidazole curing agent. The organic carbonate is one of ethylene carbonate and propylene carbonate or a mixture of the two. The metal salt is a mixture composed of one or more of zinc acetate, copper acetate, zinc gluconate, and zinc sulfate heptahydrate. The composite modified curing agent of the invention has the advantages of easy mixing with epoxy resin, low reactivity under normal temperature conditions, excellent latent performance and high curing strength. In addition, the present invention utilizes organic carbonate to modify 2-methylimidazole, which belongs to the extension of carbon dioxide resource utilization technology. |
