Abstract
A fire-extinguishing aerosol for precision electric appliance is disclosed, which includes oxidant, flammable agent, adhesive and additive. The composition of the present invention is characterized in that the oxidant is the mixture of the potassium salt and the strontium salt, in which the content of the potassium salt oxidant is more than or equal to 5 mass % to less than 15 mass % of the total mass of the composition, and the content of the strontium salt oxidant is more than 52 mass % to less than or equal to 60 mass % of the total mass of the composition. In the fire-extinguishing aerosol composition of the present invention, the particle average diameter of all components is less than 50 μm. After quenching the fire in the space in which the precision electric appliance is installed, the fire-extinguishing aerosol composition of the present invention can ensure that the dielectric resistance of the precision electric appliance is more than or equal to 100 MΩ. The fire-extinguishing aerosol composition of the present invention is more reasonable than the prior art, friendly to the environment, and applicable to the precision electric appliance.
