Embodiment 1

[0019] A fire extinguishing composition based on phosphoric acid dry powder, consisting of 6-8 parts by mass of foaming agent, 4-7 parts by mass of stabilizer, 30-40 parts by mass of flame-retardant particle mixture, and the rest is a mixture composed of aqueous solution, said The foaming agent is vegetable hydrolyzed protein or alum; the stabilizer is polyferric chloride, and the flame-retardant particle mixture is one or more of sodium bicarbonate dry powder, iron oxide particles, phosphoric acid dry powder, amino dry powder, and titanium dioxide particles The solvent of described aqueous solution is water, and solute is the mixture of one or more in ammonium chloride, sodium sulfate, melamine, potassium bisulfate.

[0020] In the case of any component content ratio in this example, it has been proved by experiments that 2L of the mixed solution is placed in a sealed container, and a pressure of 1.8-2.0 atmospheres is applied, and a spray gun mouth with a diameter of 3 mm is ...

Embodiment 2

[0025] A fire extinguishing composition based on phosphoric acid dry powder, consisting of 6-8 parts by mass of foaming agent, 4-7 parts by mass of stabilizer, 30-40 parts by mass of flame-retardant particle mixture, and the rest is a mixture composed of aqueous solution, said The foaming agent is vegetable hydrolyzed protein or alum; the stabilizer is polyferric chloride, and the flame-retardant particle mixture is one or more of sodium bicarbonate dry powder, iron oxide particles, phosphoric acid dry powder, amino dry powder, and titanium dioxide particles The mixture of; the solvent of described aqueous solution is water, and solute is the mixture of one or more in ammonium chloride, sodium sulfate, melamine, potassium bisulfate, and the mass parts of described foaming agent is 7 parts, the stabilizer's 6 parts by mass, 40 parts by mass of flame retardant particle mixture, and the rest is a mixture of aqueous solution, the solute of which is a mixture of ammonium chloride an...

Abstract

The invention discloses an extinguishment composition based on phosphoric acid dry powder. The extinguishment composition based on phosphoric acid dry powder is composed of, by mass, 9 to 12 parts ofa foaming agent, 6 to 9 parts of a stabilizing agent, 28 to 35 parts of a flame retardant particle mixture and the balance a mixture formed through a water solution. The foaming agent is plant proteinhydrolysate or alumen; the stabilizing agent is polymerization ferric chloride, the flame retardant particle mixture is a mixture of one or multiple of sodium bicarbonate powder, iron oxide particles, the phosphoric acid powder, amino group powder and titanium dioxide particles. A solvent of the water solution is water, a solute is a mixture of one or more of ammonium chloride, sodium sulfate, melamine and potassium hydrogen sulfate. An extinguishing agent can be evenly attached to oily substances, the foaming agent can be rapidly combined with non-covering areas in a dissociation manner, a covering layer is formed, necessary oxygen needed by combustion is isolated, the physical isolation between a combustible and oxygen can be formed, and the extinguishment effect 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 fire-extinguishing composition based on phosphoric acid dry powder. 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 melamine salt for fire extinguish...
