Abstract

The invention discloses a fire extinguishing agent with discrete adhesive force. The fire extinguishing agent with the discrete adhesive force comprises, by mass, 10-12 parts of foaming agent, 4-11 parts of stabilizing agent, 29-43 parts of hydrophobic solid particles, and the balance a mixture formed by an aqueous solution, wherein polyurethane or N,N-dinitroso-pentamethylene tetramine serves as the foaming agent; ferric trichloride serves as the stabilizing agent; one or a mixture of several of magnesium hydroxide particles, silicon dioxide particles and calcium carbonate particles serves as the hydrophobic solid particles; water serves as a solvent of the aqueous solution, and one or a mixture of several of ammonium dihydrogen phosphate, ammonium dibasic phosphate, ammonium phosphate and sodium phosphate serves as a solute. The fire extinguishing agent provided by the invention can be uniformly attached to oil substances; the foaming agent can rapidly and freely combine uncovered areas to form a covering layer and isolate necessary oxygen required by burning, and physical isolation is formed between combustibles and oxygen so as to achieve the effect of fire extinguishing.

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, specifically, a fire-extinguishing agent with discrete adhesion. 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 a dry powder fire extinguisher is filled with ammonium phosphate for fire extinguishing and is dry a...
