Preparation method of fire extinguishing agent with discrete adhesive force

Abstract

The invention discloses a preparation method of a fire extinguishing agent with discrete adhesive force. 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 method for preparing a fire-extinguishing agent with discrete adhesion. 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 phosphat...
