Preparing method for water-soluble foam fire-fighting composition

Abstract

The invention discloses a preparing method for a water-soluble foam fire-fighting composition. The preparing method comprises the steps that hydrophobic solid particles are placed into air drying equipment to be subjected to sufficient air drying; the hydrophobic solid particles are placed into a ball mill for ball milling; a foaming agent, a stabilizer and the hydrophobic solid particles are placed into a stirrer to be mixed and stirred; a solute is placed into clean water to be mixed to form a solution, the solution is added into a mixture of the foaming agent, the stabilizer and the hydrophobic solid particles to form a fire extinguishing agent; and the obtained fire extinguishing agent is contained into a compression resistance container, and 1.8-2.3 units of barometric pressure are applied for storage. According to the preparing method, the step of ball milling of the hydrophobic solid particles is added, the unit diameter of the hydrophobic solid particles is obviously decreased,the hydrophobic solid particles can be attached to the surface of an object catching a fire more evenly, in cooperation with foams generated by the foaming agent, an isolated film can be quickly formed under the high temperature firing environment, and quick extinguishment can be 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 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...
