Abstract:
1. A fire-extinguishing aerosol composition suitable for general electric apparatuses, comprising oxidant, combustible, adhesive, and additive; wherein, the oxidant in the fire-extinguishing compound is a mixture of potassium salt oxidant and strontium salt oxidant; the combustible is selected from guanidine nitrate, aminoguanidine nitrate, diaminoguanidine nitrate, or a combination thereof; the additive is selected from aluminum powder, carbon powder, calcium carbonate, or a combination thereof; the adhesive is selected from epoxy resin, phenolic resin, acrylic resin, or a combination thereof; in addition, the weight percents of the components in the fire-extinguishing composition are: wherein the strontium salt is strontium nitrate, strontium peroxide, strontium carbonate, strontium sulphite, strontium pyrophosphate, strontium bromide, strontium dichromate, strontium hexaboride, strontium permanganate, or a combination thereof; wherein the potassium salt is potassium nitrate, potassium chlorate, potassium perchlorate, potassium chloride, potassium nitrite, potassium carbonate, potassium citrate, or a combination thereof; and wherein the aerosol composition has electrical properties such that after the fire-extinguishing aerosol composition is exhausted from the general electric apparatus, an insulation resistance of the general electric apparatus is within the range of 20 to 100MΩ.
