A fire extinguishing composition containing sugar and sugar derivatives

Abstract

The present invention 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 invention 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 on the pyrotechnic agent, thereby improving the fire extinguishing performance of the whole fire extinguishing composition.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to an aerosol fire extinguishing composition containing sugars and sugar derivatives. Background technique [0002] Aerosol fire extinguishing technology has been recognized and widely used as one of the eye-catching halon replacement technologies in recent years. [0003] Usually, the aerosol fire extinguishing agent releases a large amount of heat when it releases the aerosol after the combustion reaction, which makes the temperature of the fire extinguishing device relatively high. Secondary fires will be caused after release. In order to reduce the injection temperature, people usually use physical cooling method and chemical cooling method. The physical cooling method is to cool the front end of the pyrotechnic agent in the fire extinguishing device by adding a cooling system, but this is easy to cause the structure of the device to Complex and bulky, complex process, hi...

Problems solved by technology

[0003] Usually, the aerosol fire extinguishing agent releases a large amount of heat when it releases the aerosol after the combustion reaction, which makes the temperature of the fire extinguishing device relatively high. Secondary fires will be caused after release. In order to reduce the injection temperature, people usually use physical cooling method and chemical cooling method. The physical cooling method is to cool the front end of the pyrotechnic agent in the fire extinguishing device by adding a cooling system, but this is easy to cause the structure of the device to Complex and bulky, complex process, high cost, and due to the existence of the cooling system, a large number of active particles are deactivated, resulting in a greatly reduced fire extinguishing performance

In addition, the chemical cooling method is to set a chemical cooling layer in the injection direction of the pyrotechnic agent. However, the existing chemical coolant will affect the fire extinguishing efficiency of the pyrotechnic agent, making it difficult for the pyrotechnic agent to penetrate the fire plume and directly reach the root of the fire source. To achieve the purpose of quickly and effectively suppressing the fire source, in addition, most of them will decompose a certain amount of gas particles that are poisonous to the human body, which is not conducive to environmental protection
