Problems solved by technology

[0005] In addition, the process of these aerosol fire extinguishing agents is also cumbersome, and the particle size of the constituent materials is required to reach more than 100 mesh, so the dust in the factory building is large, causing great dust damage to employees, etc.

Abstract

The invention relates to an aerosol extinguishing agent. The extinguishing agent is characterized by mainly comprising the following raw materials in part by weight: 25 to 34 percent of strontium nitrate serving as a first oxidant, 20 to 50 percent of guanidine nitrate serving as a second oxidant, 10 to 25 percent of copper oxide serving as a third oxidant, 2 to 10 percent of inflammable carbon powder serving as a reducing agent, 2 to 8 percent of white granulated sugar serving as an adhesive, 1 to 5 percent of alloy aluminum powder serving as a catalyst and 2 to 6 percent of industrial alcohol serving as a solvent. Novel oxidants, namely, the guanidine nitrate and the copper oxide are added, so that corrosive substances produced by the combustion of the conventional extinguishing agent are not produced in the combustion process of the extinguishing agent and protected objects are prevented from being corroded after extinguishment.

Description

technical field [0001] The invention belongs to the technical field of fire fighting and fire extinguishing, and relates to a novel thermal aerosol fire extinguishing agent and a preparation method thereof. Background technique [0002] At present, the aerosol fire extinguishing device mainly has a fire extinguishing agent that passes through an electronic starter and burns in the form of pyrotechnic powder, producing a large amount of inert gas and nano-scale solid particles. When these substances are released into the protected area, the oxygen in the air is consumed. And dilute its concentration, so that the surface of the burning material lacks oxygen and realizes fire extinguishing. [0003] According to the regulations of the industry, there are three types of aerosol fire extinguishing agents on the market, namely K type, S type and other types. They are all composed of oxidizing agents and reducing agents, and oxidizing agents are divided into single oxidizing agent...
