Abstract

The invention discloses a gel dry water fire extinguishing agent with high stability and high water-retaining property and a preparation method of the gel dry water fire extinguishing agent. The gel dry water fire extinguishing agent is of a composite structure formed by combining hydrophobic nano silicon dioxide and ferrocene to form an inert shell, combining an anion and nonionic compound solution and a liquid core gel system cross-linking solution to form a gel dry water liquid core, and wrapping the gel dry water liquid core by the inert shell. The preparation method comprises the following steps: S1, preparing an anionic and nonionic compound solution; s2, preparing a liquid core gel system cross-linking solution; s3, mixing and stirring the anionic and nonionic compound solution and the liquid core gel system cross-linking solution to obtain a gel dry water liquid core stock solution; and S4, hydrophobic nano silicon dioxide, ferrocene and the gel dry water liquid core stock solution are mixed and stirred at a high speed through a precise high-speed dispersion machine, tiny liquid drops of the gel dry water liquid core stock solution are evenly wrapped by the hydrophobic nano silicon dioxide and the ferrocene, and finally the gel dry water fire extinguishing agent is formed.
