Abstract
The present disclosure relates to a fire extinguishing composition containing saccharide and a saccharide derivative, comprising a saccharide derivative, a saccharide material and an auxiliary fire extinguishing agent, whose mass percentages are respectively: saccharide derivative 30%-60%, saccharide material 10%-40%, and auxiliary fire extinguishing agent 10%-30%. The fire extinguishing composition uses a pyrotechnic agent as a heat source and a power source, is heated and decomposed or reacts by using the heat of burning of the pyrotechnic agent, to generate a fire extinguishing material to be sprayed together with the fireworks agent, thereby achieving the fire extinguishing purpose. The fire extinguishing composition of the present disclosure uses a saccharide derivative and a saccharide material as primary ingredients, uses a pyrotechnic agent as a heat source and a power source, and is easily decomposed after being heated to generate non-toxic and harmless gas. The environment is not polluted after the ejection, the effective utilization rate of components is high, and the material obtained through decomposition can also extinguish fire, so as to generate a synergistic action…
