AI Technical Summary

Technical Problem

Existing dry powder extinguishing agents, foam extinguishing agents, water mist extinguishing agents, and carbon dioxide extinguishing agents are not very effective at extinguishing alcohol fires and are difficult to effectively put out alcohol fires.

Method used

A composite material of attapulgite dispersion and reduced graphene oxide nanosheet dispersion was used as the wall material to form microcapsules. The extinguishing agent was prepared by combining dispersant, emulsifier, suspending agent, antimony trioxide and water. The barrier effect of antimony trioxide, microcapsules and reduced graphene oxide nanosheets was used to isolate oxygen and combustibles. The fire extinguishing was achieved through the protective film formed at high temperature and the dilution effect.

Benefits of technology

It significantly improves the extinguishing effect on alcohol fires, achieving rapid and effective fire suppression through the synergistic effect of multi-layer composite materials.
