Problems solved by technology

But although the mechanism of ferrocene fire extinguishing has been theoretically studied to a certain extent, the specific application and implementation of ferrocene is still limited to theoretical research at present, and the fire extinguishing efficiency of ferrocene has not been fully utilized. Its specific implementation needs to be further studied

Abstract

The invention relates to a novel fire-extinguishing composition, which comprises 5%-39% of ferrocene and 61%-95% of a flame-retardant fire-extinguishing component by mass. The fire-extinguishing composition adopts a pyrotechnic agent as the thermal source and the power source. The high temperature generated by pyrotechnic agent combustion is utilized to heat the fire-extinguishing composition and make it undergo a decomposition reaction so as to generate fire extinguishing substances, which can be ejected together with the pyrotechnic agent to achieve a fire-extinguishing effect. In the invention, the combination ratio of the ferrocene is made accurate and optimized. The characteristic that after being heated, ferrocene can decompose or sublimate to generate fire-extinguishing substances is fully utilized. The fire extinguishing efficiency of the ferrocene composition is greatly improved, and the fire-extinguishing time is shortened.

Description

technical field [0001] The invention belongs to the technical field of aerosol fire extinguishing, in particular to an aerosol fire extinguishing composition. Background technique [0002] From 1985 to 1987, major countries in the world signed the famous "Vienna Convention" and "Montreal Protocol" to protect the ozone layer and phase out ozone-depleting substances. At present, halon fire extinguishing agents have been banned in developed countries, and other countries have also banned them. classified as phase-out substances. my country has acceded to the Convention and the Protocol in 1989 and 1991 respectively, and formulated the "National Plan for Phase-out of Substances that Deplete the Ozone Layer in China" in 1992, fulfilling our country's commitment to the international community with practical actions- my country's fire protection industry will complete the phase-out of Halon 1211 by December 31, 2005, stop the production of Halon 1301 from January 1, 2006, and stop ...
