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 agent for extinguishing fires involving liquid oily substances, comprising a mixture of 10-12 parts by mass of a foaming agent, 4-11 parts by mass of a stabilizer, 29-43 parts by mass of hydrophobic solid particles, and the rest being an aqueous solution , the foaming agent is polyurethane or N,N dinitrosopentamethylenetetramine; the stabilizer is ferric chloride, and the hydrophobic solid particles are magnesium hydroxide particles, silicon dioxide particles, A mixture of one or more of calcium carbonate particles; the solvent of the aqueous solution is water, and the solute is one of sodium chloride, sodium acetate trihydrate, sodium carbonate, potassium perchlorate, diammonium hydrogen phosphate, ammonium phosphate, and sodium phosphate One or m...

Abstract

The invention discloses a preparation method of a water-soluble foam fire extinguishing composition, which comprises the steps of putting hydrophobic solid particles into air-drying equipment for sufficient air-drying; putting the hydrophobic solid particles into a ball mill for ball milling; , stabilizer, and hydrophobic solid particles are put into a stirrer for mixing and stirring, and the solute is mixed in clear water to form an aqueous solution and add the mixture of foaming agent, stabilizer and hydrophobic solid particles in step 3 Forming a fire extinguishing agent; the obtained fire extinguishing agent is filled in a pressure-resistant container and stored at 1.8-2.3 atmospheres. In the present invention, by adding the step of ball milling the hydrophobic solid particles, the unit diameter of the hydrophobic solid particles is significantly reduced, and can be more uniformly attached to the surface of the burning object, and the foam produced by cooperating with 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 preparation method of a water-soluble foam fire-extinguishing 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 a dry powder fire extinguisher is filled with ammonium phosphate for fi...
