AI Technical Summary

Technical Problem

Existing fire extinguishing microcapsules have problems such as high risk of accidental triggering and poor adaptability to complex scenarios. In particular, they are prone to accidental release of agents due to local high temperatures in industrial environments, and the fire extinguishing efficiency of a single fire extinguishing agent is limited in scenarios where the fire spreads rapidly.

Method used

The fire extinguishing capsule employs a dual photothermal synergistic response. By setting a temperature-sensitive shell and a photosensitive shell in the inner and outer layers of the microcapsule, a core-shell-shell three-layer structure is formed. The release of the agent is controlled by a dual triggering mechanism of temperature and light signals. Flame retardants are added to the inner and outer wall materials to achieve synergistic fire extinguishing.

Benefits of technology

It improves fire extinguishing efficiency and scene adaptability, reduces the false triggering rate, ensures accurate release of agents in fire scenarios, enhances fire extinguishing efficiency and the ability to prevent reignition, and is suitable for complex fire scenarios such as electrical cabinets and data centers.
