[0015] Polysaccharide: 20%~30%

[0016] Performance regulator: 2% to 15%

[0017] Binder: no more than 2%

[0018] The second type:

[0019] Strontium nitrate: 30% to 55%

[0020] Magnesium nitrate: 5% to 20%

[0021] Urea: 5% to 10%

[0022] Dicyandiamide: 15% to 20%

[0023] Performance regulator: 2% to 8%

[0024] Binder: no more than 2%

[0025] The third type:

[0026] Magnesium nitrate: 10% to 30%

Abstract

The invention discloses a compound type aerosol extinguishing agent comprising the following components in percentage by weight: 30-75 percent of oxidizing agent, 20-50 percent of reducing agent, 2-15 percent of performance regulating agent and no more than 2 percent of binding agent. The oxidizing agent is prepared by matching any two or three matched components selected from potassium nitrate, strontium nitrate and magnesium nitrate; the reducing agent is prepared by matching two or more components selected from polyhexose, glucose, starch, sorbitol, xylitol, lactose, dicyandiamide, melamine, carbamide and sucrose; the performance regulating agent is prepared by matching one or more component selected from carbon powder, light magnesium carbonate, magnesium stearate, aluminium nitrate, hexamethylenetetramine, aluminium oxide, magnesium oxide and light metal oxide; and the binding agent is prepared by matching water or 20-30 percent of ethanol added into the water. In the invention, production raw materials have a wide source and low cost, can be constantly obtained and are safe and reliable, and burnt residues have no toxicity and good environmental protection performance.

Description

technical field [0001] The invention relates to an aerosol fire extinguishing agent, in particular to a composite hot aerosol fire extinguishing agent. Background technique [0002] Aerosol fire extinguishing agent is a kind of fire extinguishing medium of a sol system with particle size less than 5 μm formed by solid particles as the dispersed phase and gas as the dispersion medium. The aerosol fire extinguishing agent does not need a pressure-resistant container, the fire extinguishing efficiency is higher than that of the dry powder fire extinguishing agent, and the depletion index of the ozone layer is zero. Long dwell time, thus enabling total flooding, i.e. for use in enclosed spaces. Based on this characteristic, aerosol fire extinguishing agent has been paid attention to by people. The characteristics and compatibility of each component of the aerosol fire extinguishing agent are crucial to safety, environmental protection and economy. At present, the composition a...
