Abstract
Official abstract text for this publication.
A fire extinguishing agent comprising a metallocene and a dispersion medium, the metallocene being dispersed in the dispersion medium.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fire extinguishing agent comprising a metallocene, a dispersion medium and a dispersing agent, the metallocene being dispersed in the dispersion medium, wherein: the content of the metallocene is 70 to 160 ppm by weight, the dispersion medium is water, and the dispersing agent is at least one nonionic surfactant selected from the group consisting of glycerin fatty acid esters, sucrose fatty acid esters, sorbitan fatty acid esters, and acetylene alcohols. 2. The fire extinguishing agent according to claim 1 , wherein the metallocene is ferrocene. 3. The fire extinguishing agent according to claim 1 , wherein the concentration of the nonionic surfactant is 1 to 7 times the critical micelle concentration. 4. The fire extinguishing agent according to claim 1 , wherein a dispersion stability of the metallocene in the fire extinguishing agent is 1 to 20 in terms of a slope obtained by linear approximation of a curve obtained by plotting times (min.) after production of the fire extinguishing agent in abscissa against reciprocal numbers of turbidity values (NTU −1 ) of the fire extinguishing agent in ordinate. 5. A method for extinguishing fire, comprising supplying the fire extinguishing agent according to claim 1 to a burning material.
