Problems solved by technology

The cooling material can reduce the temperature of the product, but also greatly weaken the fire extinguishing performance of the product. In order to make up for the loss of fire extinguishing performance caused by the cooling layer, many products either lower the fire extinguishing level or continue to increase the quality of the actual fire extinguishing agent. The volume of the product increases, the use efficiency decreases, and the temperature of the nozzle is high, and the residue of the fire extinguishing agent is not easy to clean up. It is corrosive and will cause secondary damage

Embodiment 1

[0017] Take 1 part of nonacarbonyl ferric iron, 95 parts of potassium hydrogen tartrate, and 4 parts of hydroxypropyl methylcellulose, mix the three evenly, add an appropriate amount of water, granulate and dry, and use a rotary tablet machine to make Small pieces of Φ6. When in use, weigh 60 g of the above-mentioned fire extinguishing agent and assemble it with 50 g of aerosol generating agent for use at the same time. The fire extinguishing effect is shown in Table 1.

Embodiment 2

[0019] Take 6 parts of nonacarbonyl ferric iron, 80 parts of sodium EDTA, and 13 parts of ABC superfine dry powder, mix the three evenly, and add 1 part of acetal glue dissolved in an appropriate amount of ethanol, granulate and dry, and extrude with honeycomb ceramics Machine extruded into a Φ25 cylinder with honeycomb voids. When in use, take 3 pieces of the above-mentioned cylinders, about 60g, and assemble them with 50g of aerosol generating agent at the same time. The fire extinguishing effect is shown in Table 1.

Embodiment 3

[0021] Take 11 parts of ferrocene, 76 parts of melamine, and 9 parts of tetrabromobisphenol A, mix the three evenly, and add 4 parts of polyvinyl alcohol dissolved in an appropriate amount of water, granulate and dry it with a rotary tablet machine Make small pieces of Φ6. When in use, weigh 60 g of the above-mentioned fire extinguishing agent and assemble it with 50 g of aerosol generating agent for use at the same time. The fire extinguishing effect is shown in Table 1.

Abstract

The present invention relates to a fire-extinguishing composition, wherein the fire-extinguishing composition comprises a main fire-extinguishing component of 60% to 95% by mass and an auxiliary fire-extinguishing component of 5% to 35% by mass. In use, the fire-extinguishing composition absorbs heat generated by combustion of firework powder and produce a fire-extinguishing substance through thermal decomposition, and the fire-extinguishing substance ejects along with a hot aerosol generated by combustion of the firework powder, to achieve the fire-extinguishing effect. The fire-extinguishing composition makes up performance loss of a common cooling layer on an aerosol generating agent, enhances the fire-extinguishing performance of the whole fire-extinguishing product, and at the same time, reduces the temperature of the product at the spout.

Description

technical field [0001] The invention relates to an aerosol fire extinguishing technology, in particular to a thermal aerosol fire extinguishing composition. Background technique [0002] As an alternative to halon products, aerosol fire extinguishing technology has the characteristics of high fire extinguishing performance and no secondary pollution, and is widely used in fire extinguishing industries at home and abroad. Existing hot aerosol fire extinguishing products all use hot aerosol fire extinguishing agent as an effective fire extinguishing substance, and this fire extinguishing agent will release a large amount of heat when burning, which may cause secondary combustion, so the existing aerosol fire extinguisher or fire extinguishing device Both use physical or chemical cooling materials on the upper layer of fire extinguishing agent. The cooling material can reduce the temperature of the product, but also greatly weaken the fire extinguishing performance of the prod...
