Patent ID: 8231801

Claim:
A fire-extinguishing aerosol composition suitable for precision electric appliances, which comprises an oxidant, a flammable agent, an adhesive and an additive, wherein after using said fire-extinguishing composition for suppressing fire in a space equipped with precision electric appliances, the insulation resistance of the precision electric appliances is more than or equal to 100MΩ; the oxidant in the fire-extinguishing aerosol composition is a mixture of a potassium salt oxidant and a strontium salt oxidant; said potassium salt oxidant is one member or a combination of several members selected from the group consisting of potassium chlorate, potassium chloride, and potassium citrate; said strontium salt oxidant is one member or a combination of several members selected from the group consisting of strontium nitrate, strontium oxide, strontium carbonate, strontium sulfite, strontium pyrophosphate, strontium permanganate, strontium bromide, strontium bichromate, strontium molybdate and strontium hexaboride; the flammable agent is one member or a combination of several members selected from the group consisting of guanidine nitrate, aminoguanidine nitrate, triaminoguanidine nitrate, and diaminoguanidine nitrate; the additive is one member or a combination of several members selected from the group consisting of aluminum powder, magnesium powder, carbon powder, magnesium carbonate, calcium carbonate and potassium feldspar; the adhesive is one member or a combination of several members selected from the group consisting of phenolic resin, epoxy resin and acrylic resin; and the content of each component in percent by mass in the fire-extinguishing aerosol composition is as follows: potassium salt oxidant: more than or equal to 5% to less than 15%; strontium salt oxidant: more than 52% to less than or equal to 60%; flammable agent: 10% to 25%; additive: 2% to 20%; adhesive: 2% to 20%.
