Abstract

The invention discloses a thermal aerosol fire extinguishing agent and a preparation method thereof, which comprises: 19.6% to 31.5% of calcium dichromate, 10.8% to 22.3% of calcium hexaboride, 0.9% to 5.6% of Xylose, 11.5% to 23.6% of carbon powder, 1.3% to 4.2% of nano carboxymethyl cellulose, 11.8% to 27.5% of calcium bicarbonate, 12.1% to 20.2% of copper oxide, 0.9% to 3.7% of EDTA and 1.3% to 5.6% epoxy resin. The components of the aerosol fire extinguishing agent of the present invention have obvious synergistic effects, so that the aerosol fire extinguishing agent has good fire extinguishing ability and fire extinguishing efficiency as a whole, and has the advantages of less dosage, fast fire extinguishing speed, and high fire extinguishing efficiency. For fire extinguishing of oil fire sources.

Description

Technical field [0001] The invention relates to the field of fire extinguishing, in particular to a hot aerosol fire extinguishing agent and a preparation method thereof. Background technique [0002] Currently, the commonly used fire extinguishing agents can be roughly divided into the following categories: water-based fire extinguishing agents, gas fire extinguishing agents, powder fire extinguishing agents, aerosol fire extinguishing agents, and halon fire extinguishing agents. They are all the same, and their performance indicators have their own advantages and disadvantages. Among them: Halon extinguishing agent has the characteristics of good extinguishing effect and high efficiency. [0003] However, there are chemical components in halon fire extinguishing agents that have a greater destructive effect on the ozone layer. Since 1987, countries have gradually phased out the production and use of halon fire extinguishing agents under the restrictions of the Montreal Protocol o...
