Abstract

The invention discloses a covering type isolation fire extinguishing agent. The covering type isolation fire extinguishing agent is prepared from, by mass, 5.5-8.5 parts of a foaming agent, 3.5-9.5 parts of a stabilizing agent, 26.5-41.5 parts of hydrophobic solid particles and the balance mixture formed by a water solution. The foaming agent is benzenesulfonyl hydrazide or licorice powder. The stabilizing agent is aluminum polychlorid. The hydrophobic solid particles are a mixture of one or more kinds in montmorillonoid particles, hydrotalcite particles and hydrotalcite-like particles. The solvent of the water solution is water, and the solute of the water solution is a mixture of one or more kinds in sodium hydrogen sulfate, copper sulfate, magnesium sulfate and zinc sulfate. The fire extinguishing agent can be evenly attached to oil substances, the foaming agent can fast carry out free combination on uncovered areas to form a covering layer, essential oxygen needed for combustion is isolated, physical isolation between combustible substances and oxygen is formed, and therefore the function of fire extinguishing is achieved.

Description

technical field [0001] The invention relates to the field of fire-fighting materials, in particular to the field of fire extinguishing agents used for fire extinguishing, in particular to a covering type insulating fire extinguishing agent. Background technique [0002] A fire extinguisher is a portable fire extinguishing tool. Chemicals are placed in the fire extinguisher to put out the fire. Fire extinguishers are one of the common fire prevention facilities. They are stored in public places or places where fires may occur. Different types of fire extinguishers contain different ingredients and are specially designed for different fire alarms. Care must be taken during use to avoid adverse effects and danger. [0003] Existing fire extinguishing agents mainly include foam and dry powder, both of which have their own advantages and disadvantages. The fire extinguishing agent in dry powder fire extinguishers is filled with magnesium sulfate salt for fire extinguishing and ...
