Compound type aerosol extinguishing agent

Abstract

The invention discloses a compound type aerosol extinguishing agent comprising the following components in percentage by weight: 50%-65% of magnesium nitrate; 5%-8% of potassium nitrate; 10%-20% of dicyandiamide; 2%-5% of polysaccharide; 5%-10% of lactose; 2%-5% of capacity regulator; and no more than 2% of adhesive, wherein the capacity regulator 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 adhesive is prepared by matching water or 20%-30% of ethanol by weight 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 that uses solid particles as the dispersed phase and gas as the dispersion medium to form a sol system with a particle diameter of less than 5 μm. The aerosol fire extinguishing agent does not need a pressure container, and the fire extinguishing efficiency is higher than that of the dry powder fire extinguishing agent. The loss index of the ozone layer is zero. It can bypass obstacles and reach any corner of the protective space without being restricted by the direction, and can be used in the fire space. Longer residence time, so as to achieve full flooding and fire extinguishing, that is, used in enclosed spaces. Based on this feature, aerosol fire extinguishing agents have attracted people's attention. The properties and com...
