Problems solved by technology

Pure physical cooling will lead to complex and bulky device structure, complex process, high cost, and due to the existence of the cooling system, a large number of active particles will be deactivated, resulting in greatly reduced fire extinguishing performance
In addition, the existing aerosol fire extinguishing products are affected by the cooling performance, and the temperature of the nozzle is often too high, which is easy to cause injury to the operator

Abstract

The invention discloses a metallic oxygen-containing phthalate extinguishment composition which comprises from 30% to 95% of metallic oxygen-containing phthalate compounds and from 5% to 70% of flame-retardant extinguishment components. Pyrotechnic compositions are used as a heat source and a power source of the extinguishment composition, by igniting the pyrotechnic compositions, the extinguishment composition is heated by high-temperature heat generated during combustion of the pyrotechnic compositions to be subjected to decomposition reaction, large quantities of substances capable of extinguishing fire are generated, and the extinguishment substances and the pyrotechnic compositions are ejected via a nozzle of a fire extinguishing apparatus, so that the purpose of extinguishing the fire is achieved. The extinguishment composition is simple in composition, stable in performance, easy to store for a long time and excellent in environment-friendly performance, and is non-toxic.

Description

technical field [0001] The invention belongs to the technical field of aerosol fire extinguishing, and in particular relates to a metal oxysalt fire extinguishing composition. Background technique [0002] From 1985 to 1987, major countries in the world signed the famous "Vienna Convention" and "Montreal Protocol" on the protection of the ozone layer and the phase-out of ozone-depleting substances. In this context, developed countries in Europe and the United States have banned halon fire extinguishing agents that have a destructive effect on the ozone layer, and other countries have also classified them as phase-out substances. In 1992, my country formulated the "National Plan for the Phase-out of Ozone Depleting Substances in China". The fire protection industry in my country completed the phase-out of Halon 1211 on December 31, 2005, and all halons were stopped from January 1, 2006. The production of 1301 will stop the use of halons by the end of 2010. Therefore, it has ...
