Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0028] Preferred embodiment:

[0029] A fire extinguishing composition based on phosphoric acid dry powder, consisting of 9-12 parts by mass of foaming agent, 6-9 parts by mass of stabilizer, 28-35 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 age...

Abstract

The invention discloses a method for preparing a fire extinguishing composition based on phosphoric acid dry powder, which comprises the steps of putting the mixture of flame-retardant particles into air-drying equipment for sufficient air-drying; putting the mixture of flame-retardant particles into a ball mill for ball milling; foaming The step of putting agent, stabilizer, and flame retardant particle mixture into a stirrer for mixing and stirring, and putting the solute into clear water and mixing to form an aqueous solution is added to the foaming agent, stabilizer, and flame retardant particle mixture in step S300 The mixture is formed into a fire extinguishing agent; the obtained fire extinguishing agent is packed in a pressure-resistant container and stored at 1.8-2.3 atmospheres. In the present invention, by adding the ball milling step of the flame retardant particle mixture, the unit diameter of the flame retardant particle mixture is significantly reduced, which can be more uniformly attached to the surface of the burning object, and the foam produced by the foaming agent can be used in a high-temperature burning environment It can quickly form an insulating film and quickly extinguish the fire.

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 method for preparing 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 s...
