Problems solved by technology

During the process from gas generation to fire extinguishing, if the particle size of the homogeneous particles is too large, the gas will not be able to bear the load, and the particles will settle quickly, which will not achieve the effect of complete fire extinguishing; but if the particles are small, they are easily driven by the airflow, It may be far away from the ignition point or the location of the fire source, and it will also not be able to immediately extinguish the fire
In terms of research on the amount of solid particles, if the ratio of various elements in the formulation of the agent is unreasonable, the amount of gas will be small and the amount of solid particles will be too much, resulting in more residues, and it will also not be able to play an effective fire extinguishing role.

Embodiment 1

[0023] An aerosol fire extinguishing composition with low residue and high dielectric strength, the composition is made of 40% oxidizing agent, 30% reducing agent, 5% performance regulator, 5% adhesive and 20% coating agent in parts by mass. become. Strontium nitrate, strontium nitride and other strontium salts can be selected as the oxidizing agent. The oxidizing agent is oxidizing, and it itself is reduced, among which nitrate, etc. are reduced to N0, N02, and N2 in the chemical reaction. The pyrolysis products of solid particles exist in the form of steam or ions, and instantly adsorb and react with active groups such as H•, OH• and O•, thereby consuming fuel active groups and inhibiting the chain reaction of combustion.

[0024] Among them, the metal oxide produced by the oxidation-reduction reaction reacts with the combustion substance carbon at high temperature, absorbs part of the heat of the combustion fire source, and reduces the flame temperature, so the combustion r...

Embodiment 2

[0027] An aerosol fire extinguishing composition with low residue and high dielectric strength, which is made of 30% oxidizing agent, 25% reducing agent, 8% performance modifier, 7% adhesive and 30% coating agent in parts by mass The oxidizing agent comprises 70% of strontium nitrate and 30% of strontium nitride by mass parts; , 5-dithiophene 70%, 4,4'-bis(2-methoxystyrene) biphenyl 30%; adhesives include phenolic resin 45%, melamine glue 35%, 100-500CS silicone oil 20%; package The coating agent includes 70% diethyl carbonate, 10% dimethyl carbonate, 5% soap base, and 15% solid paraffin. The prepared oxidizing agent, reducing agent, performance modifier, binder and coating agent are mixed and stirred to form.

Embodiment 3

[0029] An aerosol fire extinguishing composition with low residue and high dielectric strength, which is made of 35% oxidizing agent, 30% reducing agent, 5% performance regulator, 6% adhesive and 24% coating agent in parts by mass ; Oxidizing agent comprises strontium nitrate 50% and strontium nitride 50% by mass parts; , 30% of 5-dithiophene, 70% of 4,4'-bis(2-methoxystyrene) biphenyl; adhesives include 45% of phenolic resin, 35% of epoxy resin, 20% of 100-500CS silicone oil; The coating agent includes 60% diethyl carbonate, 20% soap base, and 20% solid paraffin. The prepared oxidizing agent, reducing agent, performance modifier, binder and coating agent are mixed and stirred to form.

Abstract

The invention provides a low-residue and high-insulation-strength aerosol fire extinguishing composition, which comprises the following material components by mass: 30%-60% of an oxidant, 20%-40% of areducing agent, 2%-10% of a performance regulator, 5%-10% of an adhesive and 10%-30% of a coating agent. According to the invention, the aerosol fire extinguishing composition is good in fire extinguishing effect and less in residue; the hot aerosol fire extinguishing agent particles are subjected to coating treatment, so that the aerosol fire extinguishing agent particles have high insulating strength, namely, the condition that conductive substances form on the surface of a sprayed object to corrode and damage equipment can be avoided; and the flame temperature is reduced, the combustion reaction is inhibited, and after-combustion is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing compositions, in particular to an aerosol fire extinguishing composition with less residue and high dielectric strength. Background technique [0002] Aerosol fire extinguishing technology, which generates a large amount of aerosol gas through the decomposition of fire extinguishing agent combustion reaction, and the sprayed aerosol gas completely floods the protected area to achieve the purpose of fire extinguishing. Aerosol fire extinguishing agent is more and more widely used in different fields due to its high fire extinguishing ability, the ability to extinguish fire in a fully submerged manner, and being environmentally friendly, able to be stored under normal pressure and without pressure-resistant devices. Aerosols are different from halon and inert gas halon replacement technologies, and have no damage to the ozone layer. They use their own oxidation-reduction reactions to exti...
