AI Technical Summary

Technical Problem

In the prior art, the use of perfluorohexanone as the fire extinguishing agent has problems such as low boiling point leading to volatile and storage difficulties, and the use of auxiliary materials during the microcapsule manufacturing process leads to a reduced performance of fire extinguishing.

Method used

The perfluorohexanone microcapsules with a multi-layer shell structure are used to adjust the appearance and performance of the microcapsules by using a variety of polymer materials in the first and second shells of the microcapsules, so that they soften and rupture at 80-130°C, releasing perfluorohexanone for fire extinguishing.

Benefits of technology

Improves the stability and fire extinguishing performance of perfluorohexanone microcapsules, extends its service life, and simplifies storage and application processes, suitable for a variety of fire extinguishing materials and environments.

Abstract

The present invention provides a perfluorohexanone microcapsule fire extinguishing material and a method for producing the same. It belongs to the technical field of fire extinguishing agent application. Perfluorohexanone microcapsules have a core wall ratio of The perfluorohexanone is absorbed by auxiliary materials / fillers, and high boiling point solvents are used. It is not necessary to dissolve trifluorohexanone. By applying a polymeric secondary coating to the microcapsule, the strength of the microcapsule shell is improved and the pelvis is Reduces the volatilization loss of fluorohexanone and is a perfluorohexanone microencapsulant. Solving the problem of short storage time of materials and increasing the commercial application value of perfluorohexanone The perfluorohexanone microcapsules are then further mixed with various materials. By combining with the materials and interfaces, perfluorohexanone microcapsules are the main component. Various fire extinguishing materials can be obtained. Microcapsule dry powder, various thicknesses of fire extinguishing stickers, fire extinguishing blankets , and can be configured to conform to a variety of surfaces, such as firefighting suits.
