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 ...
