Embodiment Construction

[0026] 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.

[0027] Preferred embodiment:

[0028] An alkali-resistant fire extinguishing agent is composed of 5-13 parts by mass of foaming agent, 4-9 parts by mass of stabilizer, 29-42 parts by mass of hydrophobic solid particles, and the rest are a mixture of aqueous solutions. The agent is N,N dinitrosopentamethylenetetramine or azodicarbonamide; the stabilizer is polyaluminum iron silicate, and the hydrophobic solid particles are attapulgite particles, zeolite particles, and zeolite-like particles A mixture of one or more of them; the solvent of the aqueous solution is water, and the solute is a mixture of one or more of ammonium molybdate, sodium molybdate, sodium silicate, and chromium sulfate. The quality of the blowing agent Parts are 7 parts, the mass parts of the stabilizer are 6 parts, the mass parts of the...

Abstract

The invention discloses a preparation method of an alkali-resistant fire extinguishing agent. The preparation method comprises the steps that (1) hydrophobic solid particles are put into air-drying equipment to be fully air-dried; (2) the hydrophobic solid particles are put into a ball mill to be subjected to ball milling; (3) a foaming agent, a stabilizing agent and the hydrophobic solid particles are put into a stirrer to be mixed and stirred; (4) a solute is put into clear water and mixed to form an aqueous solution, and the mixture of the foaming agent, the stabilizing agent and the hydrophobic solid particles in the step (3) is added into the aqueous solution to form the fire extinguishing agent; and (5) the obtained fire extinguishing agent is contained in a pressure-resistant container, and 1.8-2.3 atmospheric pressure is applied to the fire extinguishing agent for storage. According to the preparation method, the step of ball milling of the hydrophobic solid particles is added; the unit diameter of the hydrophobic solid particles is obviously reduced so that the hydrophobic solid particles can be attached to the surface of a burning object more uniformly; the hydrophobic solid particles are used in cooperation with foam generated by the foaming agent, and an isolation film can be rapidly formed under a high-temperature burning environment to extinguish a fire quickly.

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, and specifically relates to a preparation method of an alkali-resistant fire-extinguishing agent. 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] The existing fire extinguishing agents mainly include foam and dry powder, both of which have their own advantages and disadvantages. The fire extinguishing agent in the dry powder fire extinguisher is filled with sodium silicate...
