Synthesis of phosphorus-containing metalimidazole complex flame-retardant latent curing agents and their effect on the curing, flame retardancy and smoke suppression properties of epoxy resin

Ph.D Student:

Wang Jingsheng

Project Background:

How to simultaneously achieve excellent flame retardancy, smoke suppression, overall performance, as well as long-lasting latency and rapid curing is a challenging issue in the field of epoxy resin applications. To address this, the project aims to molecularly design and synthesize a class of phosphorus-containing metal-imidazole complex curing agents through intrinsic flame retardant technology, smoke suppression technology, and latent fast-curing technology in the organic combination of modified curing agents. This work provides valuable insights for the design and preparation of high-performance single-component epoxy resin systems.

Aims & Goals:

1. To explore new methods for the molecular design and synthesis of imidazole-based curing agents with metal ions and phosphorus-containing groups;

2. To obtain a multifunctional curing agent that integrates "long-lasting latent, rapid curing, and efficient flame retardant and smoke suppression" characteristics;

3. To open up new pathways for the design and preparation of high-performance single-component epoxy resin systems.

Outcomes:
