Fire-extinguishing agent and preparation method thereof

Abstract

The invention discloses a fire-extinguishing agent. The fire-extinguishing agent is prepared by uniformly mixing hydrophilic solid powder and water or an aqueous solution, adding hydrophobic solid particles and then carrying out mixing and dispersing, wherein the hydrophilic solid powder is one or more of magnesium hydroxide powder, aluminum oxide powder, aluminum hydroxide powder, magnesium carbonate powder, calcium carbonate powder, calcium hydroxide powder, zinc borate powder, montmorillonoid powder, hydrotalcite powder, hydrotalcite like compound powder, fly ash powder, diatomite powder, mica powder and attapulgite powder. The fire-extinguishing agent disclosed by the invention can exert stifling, cooling, separating and chemically restraining functions at the same time, and has the advantages of no toxicity, small environment pollution, high fire extinguishing efficiency and the like. According to the fire-extinguishing agent disclosed by the invention, the hydrophilic solid powder with a certain fire extinguishing performance and smaller solubility in water is added into a water phase so as to reduce the using amount of water-soluble substances, thus the cost of the fire-extinguishing agent is reduced when higher fire-extinguishing efficiency is kept, and the fire-extinguishing agent is easier to clean after being used for extinguishing fire.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a fire extinguishing agent and a preparation method thereof. Background technique [0002] Water is the most commonly used extinguishing agent, and its thermal properties allow it to be used in the extinguishing process for most types of fires. However, due to the strong fluidity of water, under normal circumstances, most of the water used for fire extinguishing is lost before it can take effect, which leads to a low utilization rate of water fire extinguishing and is easy to cause secondary losses. Chinese patent 201010605644.5 provides a fire extinguishing agent, the fire extinguishing agent effectively restricts the free flow of water by binding water in a solid shell, has a certain accumulation, and reduces the amount of fire extinguishing agent and improves the fire extinguishing effect. The secondary disaster caused by water during fire extinguishing,...

However, due to the strong fluidity of water, under normal circumstances, most of the water used for fire extinguishing is lost before it can take effect, which leads to a low utilization rate of water fire extinguishing and is prone to secondary losses

Chinese patent 201010605644.5 provides a fire extinguishing agent, the fire extinguishing agent effectively restricts the free flow of water by binding water in a solid shell, has a certain accumulation, and reduces the amount of fire extinguishing agent and improves the fire extinguishing effect. The secondary disaster caused by water during fire extinguishing, but the fire extinguishing agent in the above-mentioned patent only uses an aqueous solution with a certain fire extinguishing performance as the basic raw material, and does not use a hydrophilic solid powder with a certain fire extinguishing performance as an effective component, and the cost is relatively high
