Abstract
The invention provides a preparation method of a superfine powder fire extinguishing agent based on a porous carbon fluoride material. The fire extinguishing agent is prepared by adding main components of the fire extinguishing agent into inner holes of the carbon fluoride material by utilizing the porous characteristic of the micro-nano porous carbon fluoride material, so that the particle size of the powder fire extinguishing agent is determined by the particle size of the carbon fluoride material, and the agglomeration phenomenon of effective components of the fire extinguishing agent due to deliquescence can be prevented due to the super-hydrophobic characteristic of the carbon fluoride material. Meanwhile, the carbon fluoride material contains a large amount of fluorine elements, so that the fire extinguishing effect of the powder fire extinguishing agent can be further improved.
Description
Technical Field
The invention belongs to the technical field of preparation of superfine powder fire extinguishing agents, and particularly relates to a preparation method of a superfine powder fire extinguishing agent based on a porous carbon fluoride material.
Background
The powder fire extinguishing agent is considered to be one of potential substitutes of a 'Halon' fire extinguishing agent due to the excellent characteristics of high fire extinguishing efficiency and low ODP and GWP values. The key technology for improving the performance of the powder extinguishing agent is to further refine the powder extinguishing agent particles to prepare the micro-nano-grade superfine powder extinguishing agent. However, the effective components of the existing powder fire extinguishing agent are mainly hydrogen phosphate and bicarbonate, and the prepared micro-nano superfine powder fire extinguishing agent is easy to agglomerate due to the fact that inorganic salts are easy to deliquesce, so that the performance of the fire extinguishing agent is reduced. Although the fire extinguishing agent can be subjected to hydrophobic treatment by adding silicone oil, the treated fire extinguishing agent particles are still large and cannot meet the performance requirements of the micro-nano superfine powder fire extinguishing agent. The effective components of the powder extinguishing agent are loaded into the nano porous carrier with large specific surface area, so that the agglomeration problem can be solved, and the effective utilization rate of the powder extinguishing agent can be improved. Currently, commonly used porous carriers include alumina, zeolite, perlite, bentonite, asbestos, and the like, but these inorganic porous carriers have a small specific surface area and are not easily controlled in particle size and pore size. Therefore, the development of new micro-nano ultrafine powder fire extinguishing agents is required.
The porous carbon fluoride material as a nano porous material not only has ultrahigh specific surface area and rich inner pore channels, but also has ultrahigh hydrophobic property due to containing a large amount of fluorine atoms. Therefore, the carbon fluoride material can be used as a carrier for preparing the micro-nano powder extinguishing agent, and meanwhile, the fire extinguishing effect of the powder extinguishing agent can be further improved due to a large amount of fluorine elements contained in the carbon fluoride material.

(4) and mixing the fire extinguishing agent material loaded by the porous carbon fluoride and the fire extinguishing agent auxiliary material according to a proportion to finally obtain the high-efficiency superfine powder fire extinguishing agent.
In the step (1), the powder fire extinguishing agent base material is selected from at least one of ammonium monohydrogen phosphate, ammonium dihydrogen phosphate, potassium dihydrogen phosphate, sodium bicarbonate and potassium bicarbonate.
In the step (1), the weight ratio of water to ethanol in the mixed solution of water and ethanol is 15-20: 1-6.

In the step (2), the mass ratio of the porous carbon fluoride to the saturated solution of the powder fire extinguishing agent base material is 1-10: 90-99.
In the step (3), the stirring speed is 800-.
In the step (4), the fire extinguishing agent auxiliary material is selected from at least one of zeolite, perlite, magnesite, mica powder, talcum powder, bentonite and hydrophobic white carbon black.
In the step (4), the mass ratio of the fire extinguishing agent material loaded by the porous carbon fluoride to the fire extinguishing agent auxiliary material is 90-60: 40-10.
The invention provides a preparation method of a superfine powder fire extinguishing agent based on a porous carbon fluoride material, which mainly adopts the technical principle that: the main component of the fire extinguishing agent is added into the inner hole of the carbon fluoride material by utilizing the porous characteristic of the micro-nano porous carbon fluoride material, so that the particle size of the powder fire extinguishing agent is determined by the particle size of the carbon fluoride material, and the agglomeration phenomenon of the effective component of the fire extinguishing agent due to deliquescence can be prevented due to the super-hydrophobic characteristic of the carbon fluoride material.
