Abstract

The invention discloses a preparation method for an aerosol fire-extinguishing agent. The preparation method comprises the steps that firstly, potassium nitrate, strontium nitrate, potassium citrate, cane sugar and sodium bicarbonate are ground and screened through a 100-mesh sieve; secondly, 39.0-40.0% of potassium nitrate by mass, 26.5-27.5 % of strontium nitrate by mass, 14.5-15.0 % of potassium citrate by mass, 17.5 % of cane sugar by mass and 1-1.5 % of sodium bicarbonate by mass are sufficiently blended and poured into a specially-made die to prepare a formed fire-extinguishing agent column; thirdly, the formed fire-extinguishing agent column is soaked into a phenolic resin alcoholic solution with the mass ratio being 45.5% for ten seconds; and fourthly, the fire-extinguishing agent column is placed into a drying oven at the temperature of 80 DEG C to be dried for 24 hours, so that the finished fire-extinguishing agent is obtained. The fire-extinguishing agent prepared through the preparation method is high in fire extinguishing speed and good in effect.

Description

A kind of preparation method of aerosol extinguishing agent
Technical field
The present invention relates to chemical technical field, particularly to a kind of preparation method of aerosol extinguishing agent.
Background technology
Aerosol refers to the colloidal sol with solid or liquid as dispersion phase, being formed by disperse medium with gas.In general, This thing system is stable or metastable, and the particle diameter of its liquid phase or solid-phase component is less than 1 μm.Aerosol fire-extinguishing technology is A kind of new high-tech fire-fighting technique growing up on the basis of military pyrotechnic, early in the sixties in last century section of China This technology is applied to large oil tank fire extinguishing by skill personnel, and achieves important breakthrough, here it is earliest aerosol technology.Previous generation Discipline the eighties, former Soviet Union scientific worker, test the aerosol fire-extinguishing technology that can put out a fire in total flooding mode successfully, closely several Year becomes potentiality fire-fighting technique using aerosol fire-extinguishing, is mainly used in putting out library, archives, transport facility, machine room Etc. the initial fire disaster of closing space, this technology is that the substitution studies breathing out imperial fire-fighting technique open a new approach.
Aerosol extinguishing agent extinguishing mechanism is: the work in the solid or liquid aersol particle and flame of burning generation Property base such as o, h, oh etc. occur chemically and physically to act on, such as absorb oxygen, starvation, absorb the effect such as heat, stop burning Reaction is persistently carried out, to reach the purpose of fire extinguishing.
In terms of the coolant research and development of aerosol extinguishing agent, China has shutting mechanism and the relevant personnel all to do substantial amounts of work Make, achieve certain effect.It is broadly divided into physics cooling method and chemical cooling method, the wherein cooling-down effect of physics cooling method not Enough ideals, after once putting out a fire, easily cause the tragedy of spot fire.
Content of the invention
The invention aims to overcoming the deficiencies in the prior art, provide a kind of preparation method simple, extinguishing effect is relatively The preparation method of good aerosol extinguishing agent.
For solving this technical problem, the technical scheme of employing is:
A kind of preparation method of aerosol extinguishing agent, comprises the steps:
1st, respectively potassium nitrate, strontium nitrate, potassium citrate, sucrose, sodium bicarbonate are ground and cross 100 mesh sieves;
2nd, by each composition after above-mentioned sieving in mass ratio potassium nitrate 39.0~40.0%, strontium nitrate 26.5~27.5%, Potassium citrate 14.5~15.0%, sucrose 17.5%, sodium bicarbonate 1~1.5% are sufficiently mixed and obtain extinguishing chemical powder materials;
3rd, the extinguishing chemical powder materials of mix homogeneously are poured into the special die of a diameter of 2.5cm, set the pressure of forcing press For 2.5mpa, the pressing mold time is 8min, obtains the extinguishing chemical post of molding;
4th, 10 seconds in the phenolic resin alcoholic solution being 45.5% by molding extinguishing chemical post immersion mass fraction;
5th, oven for drying 24h more above-mentioned extinguishing chemical post being put into 80 DEG C obtains extinguishing chemical finished product.
Extinguishing chemical finished product is loaded in special fire extinguisher sleeve, eruption fire extinguishing of igniting in a suitable manner.
Extinguishing mechanism is: solid or liquid that the aerosol extinguishing agent of negative oxygen balance proportioning is formed in burning ejection process Aerosol comprises a large amount of non-complete oxidation products, such as c, ch, cn etc., and that is, aerosol has stronger reproducibility, when connecing with flame When tactile, can occur chemically and physically to act on active group such as o, h, the oh etc. in flame, lead to the oxidability of flame to decline, combustion Burning weakens;Another aspect aerosol forms a tunic, isolation gasoline and air contact on gasoline surface, realizes fire extinguishing.
The extinguishing chemical preparing has the advantage that
1) when putting out a fire, cooling effect is notable, and blow-off velocity is fast, effect is good, restrained effectively the generation of spot fire.
2) gas producing in fire extinguishing procedure is nontoxic, harmless.
The more existing conventional fire extinguisher small volume of aerosol fire extinguisher 3) made using this extinguishing chemical, Portable belt, price be low, Easy to operate, safe and reliable.
4) can achieve the reuse of shell.
Specific embodiment
Following examples are raw materials used, and to be analysis pure.The feature that the invention is further illustrated by the following examples, but The invention is not limited in following examples.
Embodiment 1
A kind of preparation method of aerosol extinguishing agent, respectively by potassium nitrate, strontium nitrate, potassium citrate, sucrose, sodium bicarbonate Grind and cross 100 mesh sieves;Each composition after above-mentioned sieving is weighed by mass fraction: potassium nitrate 39.5%, strontium nitrate 27.0%, Potassium citrate 14.5%, sucrose 17.5%, the ratio of sodium bicarbonate 1.5% are sufficiently mixed;Extinguishing chemical forerunner by mix homogeneously Pour special die into, set the pressure of forcing press as 2.5mpa, the pressing mold time is 8min, take out after molding;And immerse quality and divide 10 seconds in the phenolic resin alcoholic solution for 45.5% for the number, the baking oven that the aerosol post having wrapped up firming agent is put into 80 DEG C dries Dry, take out after 24h and obtain extinguishing chemical finished product.
Embodiment 2
A kind of preparation method of aerosol extinguishing agent.Weigh each composition: potassium nitrate 39.0%, nitric acid by following mass fraction Strontium 27.5%, potassium citrate 15.0%, sucrose 17.5%, sodium bicarbonate 1.0%, its preparation method is with embodiment 1.
