Abstract

The invention discloses a reparation method of a fire extinguishing agent for a liquid fire. The preparation method comprises the steps that hydrophobic solid particles are put into air-drying equipment to be fully air-dried; the hydrophobic solid particles are put into a ball grinder for ball grinding; a foaming agent, a stabilizing agent and the hydrophobic solid particles are put into a stirrer to be mixed and stirred; solutes are put into clear water to be mixed, a water solution is formed to be added into a mixture of the foaming agent, the stabilizing agent and the hydrophobic solid particles in the third step to form the fire extinguishing agent; and the obtained fire extinguishing agent is contained in a pressing resisting container, and 1.8-2.3 atmospheres of pressure are applied for storage. According to the preparation method, the step of carrying out ball grinding on the hydrophobic solid particles is added, the unit diameter of the hydrophobic solid particles is remarkably reduced, the fire extinguishing agent can be attached to the surface of a fire object more evenly, an isolation film can be fast formed under the high-temperature burning environment in cooperation with foam generated by the foaming agent, and fast fire extinguishing 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 method for preparing a fire extinguishing agent used for liquid fires. 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 disodium hydrogen phosp...
