Fire-extinguishing composition containing sugars and sugar derivatives

Abstract

The invention relates to a fire-extinguishing composition containing sugars and sugar derivatives. The fire-extinguishing composition comprises the following components in percentage by mass: 30-60% of sugar derivatives, 10-40% of sugars and 10-30% of assistant fire-extinguishing agent. In the fire-extinguishing composition, fireworks drug is used as heat source and power source; the fireworks drug is driven to decompose or react in heating by the high temperature of the combustion of the firework drug, and the generated fire-extinguishing substances are sprayed out together with the fireworks drug so as to extinguish fire. In the fire-extinguishing composition, sugars and sugar derivatives are used as the main materials, and fireworks drug is used as the heat source and power source, so that the fire-extinguishing composition is easy to decompose and generate nontoxic and harmless gas in heating, and is pollution-free after being sprayed; the effective using rate of each component is high, and the decomposed materials also can extinguish fire so as to generate synergistic function to the fireworks drug, therefore, the fire-extinguishing efficiency of the whole fire-extinguishing composition is improved.

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
