Abstract

The invention discloses an efficient foaming type cellulose hydrogel fire extinguishing agent, and belongs to the technical field of fire extinguishing agent production. The fire extinguishing agent is prepared from the following raw material components: A, a cellulose material, B, bicarbonate, C, soluble aluminum salt, and D, water. The preparation method comprises the following steps of completely dissolving 1 part of the component A in 50-200 parts of water to obtain a solution I, wherein the mass fraction of the component A in the solution I is 0.5-2 wt%; dissolving 1 part of the componentB in 100-200 parts of water to obtain a solution II, wherein the mass fraction of the component B in the solution II is 0.5-1wt%; mixing the solution I and the solution II in a closed space to obtaina solution III; dissolving one part of the component C in 100-200 parts of water to obtain a solution IV, wherein the mass fraction of D in the solution IV in water is 0.5-1 wt%; and spraying the mixed solution III and the mixed solution IV to the surface of the comburent at the same time or spraying the mixed solution III to the surface of the comburent firstly, and then spraying the mixed solution IV to the surface of the comburent.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing agent production, and in particular relates to a high-efficiency foaming cellulose hydrogel fire extinguishing agent. Background technique [0002] Fire is the most common disaster that seriously endangers people's lives and property and directly affects economic development and social stability. Reasonable use of fire extinguishing materials can greatly reduce casualties and property losses in fires. There are many types of thermal insulation fire extinguishing materials available in the market with different performances. According to the fire extinguishing mechanism, they can be roughly divided into two categories: physical fire extinguishing materials (water, foam, carbon dioxide, nitrogen, argon and other inert gases, fire blankets, etc.) and chemical fire extinguishing materials. Materials (halogen fire extinguishing agent, dry powder fire extinguishing agent, etc.). However, th...
