Embodiment Construction

[0022] 30g of the prepared sheet fire extinguishing composition is added respectively in the fire extinguishing device that 20gK type hot aerosol generating agent is housed, respectively in 1.0m 3 The distributed fire extinguishing test was carried out in the test chamber; the test results are shown in Table 1. The comparative example was selected as 20 g of commercially available K-type thermal aerosol generating agent.

[0023] Table 1 Comparison of various components and test results

[0024]

[0025] As can be seen from the test data in the table above, the fire extinguishing composition of embodiment 1-7 of the present invention is at 1.0m 3 When the distributed fire extinguishing test is carried out in the test chamber, the fire extinguishing performance is better than that of 20g commercially available K-type hot aerosol generator.

[0026] The test method is in accordance with the concentration distribution test method of 7.13 in GA 499-2004, at 1m 3 The fire ext...

Abstract

The invention discloses a fire extinguishing composition for generating a fire extinguishing substance through chemical reaction among components at high temperature, which is characterized by comprising the following components in percentage by mass: 50 to 90 percent of flame retardant, 5 to 30 percent of oxidant, 5 to 10 percent of reducing agent and 0 to 10 percent of adhesive. During use, smoke and fire agents are taken as a heat source and power source, and by igniting the smoke and fire agents and utilizing the high temperature through combustion of the smoke and fire agents, the oxidant and the reducing agent in the fire extinguishing composition are reacted to generate an active fire extinguishing substance for extinguishing fire. Different from the traditional aerosol generating agent, the fire extinguishing composition does not need an external heat source, and does not combust. Compared with the traditional aerosol generating agent, the fire extinguishing composition is more high-efficiency and more safe.

Description

technical field [0001] The invention belongs to the field of fire protection, and relates to a fire extinguishing composition and the use of chemical fire extinguishing substances, in particular to a fire extinguishing composition that produces a fire extinguishing substance through a chemical reaction at high temperature. Background technique [0002] Since people discovered that halon fire extinguishing agents have seriously damaged the earth's atmospheric ozone layer, the international community and our government have begun to phase out halon fire extinguishing agents. Gas fire extinguishing systems, dry powder fire extinguishing systems and water system fire extinguishing systems are environmentally friendly. Extinguishing agents are widely used as an alternative to halon fire extinguishers. [0003] The mechanism of carbon dioxide, IG541 and other inert gas fire extinguishing is physical fire extinguishing, which is to suffocate the fire by reducing the oxygen concentr...
