Abstract

The invention discloses an adhesive flame retardant composition, which is composed of 5.5-8.5 parts by mass of foaming agent, 3.5-9.5 parts by mass of stabilizer, 26.5-41.5 parts by mass of hydrophobic solid particles, and the rest is aqueous solution mixture, the foaming agent is benzenesulfonyl hydrazide or licorice powder; the stabilizer is polyferric chloride, and the hydrophobic solid particles are sodium acetate trihydrate, sodium carbonate, hydrotalcite particles, and hydrotalcite-like particles A mixture of one or more; the solvent of the aqueous solution is water, and the solute is a mixture of one or more of sodium bisulfate, dilute hydrochloric acid with a concentration of 8%, copper sulfate, magnesium sulfate, and zinc sulfate. The fire extinguishing agent provided by the present invention can evenly adhere to the oily substance, and the foaming agent can rapidly combine the uncovered area freely to form a covering layer, which isolates the necessary oxygen needed for combustion, and forms combustibles and The physical isolation between oxygen has achieved 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, in particular to an adhesive flame-retardant composition. 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 is dry and e...
