Embodiment Construction

[0042] Now in conjunction with embodiment the fire extinguishing composition containing amino acid compound of the present invention is further described:

[0043] Fire extinguishing composition of the present invention carries out following test, and it is compared with existing fire extinguishing composition in the identical experimental condition of same device, and result is as follows:

[0044] 50g of the prepared sheet fire extinguishing composition is added respectively in the fire extinguishing device that 50gK type hot aerosol generating agent is housed, carries out the fire extinguishing test according to GA86-2009 clause 6.3.2 respectively, and the fire extinguishing grade is selected as 8B; The K-type thermal aerosol generating agent sold is also tested according to the same method. The test results are shown in Table 1.

Abstract

The invention relates to a fire-extinguishing composition containing amino acid compounds. The fire-extinguishing composition comprises the following components in percentage by mass: 10-70% of amino acid and 30-90% of fire retardant; and in the fire-extinguishing composition, fireworks drug is used as heat source and power source, and the fire-extinguishing composition is driven by setting fire to the fireworks drug to react to generate a large amount of fire-extinguishing substances which are sprayed out together with the fireworks drug to extinguish fire. By adopting the amino acid compounds and through using the characteristic of low toxicity of amino acid, the fire-extinguishing composition has no harm to people and livestock; and in addition, the amino acid compounds decompose and generate various aerosol fire-extinguishing substances which are excellent in fire-extinguishing effect, therefore, the fire-extinguishing efficiency of the fire-extinguishing composition is improved.

Description

technical field [0001] The invention relates to a fire extinguishing composition, in particular to a fire extinguishing composition using pyrotechnic agent as heat source and power source. Background technique [0002] Existing aerosol fire extinguishing agents mainly include S-type and K-type fire extinguishing agents. Through comprehensive analysis of their performance characteristics, their shortcomings mainly include: aerosol fire extinguishing agents are all released a large amount of gas, active Particles, through the chain scission reaction of active particles, cover and suffocate with a large amount of gas, to achieve the purpose of fire extinguishing combining chemistry and physics. The aerosol generating agent releases a large amount of heat when it undergoes a combustion reaction to release the fire extinguishing substance. In order to effectively reduce the temperature of the device and the aerosol and avoid secondary fires, it is necessary to increase the coolin...
