Currently common aerosol fire extinguishing agents include K-type aerosol fire extinguishing agents and S-type aerosol fire extinguishing agents.
The K-type aerosol fire extinguishing agent is mainly composed of potassium oxide, potassium carbonate and potassium bicarbonate, the potassium oxide, the potassium carbonate and the potassium bicarbonate after being sprayed out have strong moisture absorption capacity, electrolyte potassium hydroxide can be generated under the action of water, and the potassium hydroxide has strong corrosiveness and conductivity, so that the K-type aerosol fire extinguishing agent cannot be applied to fire extinguishing scenes such as precision instruments, cultural relics and documents.

This invention may be embodied in many different forms and is not limited to the embodiments described herein.

In the invention, the technical characteristics described in an open mode comprise a closed technical scheme composed of the listed characteristics and also comprise an open technical scheme comprising the listed characteristics.
An embodiment of the invention provides a coolant, which comprises the following components in percentage by mass:
30% -70% of organic acid,
15% -65% of organic polyol
1-15% of adhesive;
the organic acid, the organic polyol and the adhesive are all solid at normal temperature; the coolant is used for forming temperature-sensitive flocculation gel capable of complexing with fire extinguishing particles at the temperature of more than or equal to 600 ℃.
Specifically, the coolant can be decomposed or sublimated when heated, and the decomposed or sublimated organic acid and the organic polyol in the coolant are subjected to copolymerization reaction to generate temperature-sensitive flocculation gel, so that the temperature-sensitive flocculation gel can be subjected to complexation reaction with fire extinguishing particles in the aerosol fire extinguishing agent.
In addition, the coolant can absorb heat in the spraying process of the aerosol fire extinguishing agent, so that the nozzle temperature of the aerosol fire extinguishing device can be effectively reduced.
In a specific example, the composition comprises the following components in mass percent:
50-70% of organic acid,
20% -45% of organic polyol
5 to 10 percent of adhesive.
In a specific example, the organic acid may be, but is not limited to, one or more of lauric acid, sorbic acid, myristic acid, alginic acid, furoic acid, alpha-ketoglutaric acid, crotonic acid, topanoic acid, behenic acid, fumaric acid, chloromandelic acid, 3-nitrophthalic acid, 4-nitrophthalic acid, 2-naphthoic acid, terephthalic acid, phthalic acid, 3, 4-dihydroxybenzoic acid, 4-methylcinnamic acid, p-methoxybenzoic acid, maleic acid, gallic acid, 1-hydroxy-2-naphthoic acid, L-tartaric acid, m-methylbenzoic acid, barbituric acid, 3-methylcinnamic acid, pyromellitic acid, 3-isobutylglutaric acid, 2-methoxybenzoic acid, phthalic acid, mirabi acid, cinnamic acid, malonic acid, m-hydroxybenzoic acid, creatine, o-ethoxybenzoic acid, 3, 5-diaminobenzoic acid, and p-hydroxybenzoic acid.
Further, the organic acid may be, but is not limited to, one or more of sorbic acid, furoic acid, behenic acid, terephthalic acid, 3, 4-dihydroxybenzoic acid, 4-methyl cinnamic acid, 3-methyl cinnamic acid, and cinnamic acid.
In a specific example, the organic polyol may be, but is not limited to, a mixture of one or more of dipentaerythritol, coniferyl alcohol, cinnamyl alcohol, pinacol, 4-methylbenzyl alcohol, and polyvinyl alcohol; and/or
Further, the organic polyol may be, but is not limited to, a mixture of one or more of dipentaerythritol, coniferyl alcohol, cinnamyl alcohol, pinacol, and polyvinyl alcohol.
In a specific example, the binder may be, but is not limited to, a mixture of one or more of methylcellulose, ethylcellulose, carboxymethylcellulose, hydroxypropyl methylcellulose, cellulose acetate butyrate, hydroxyethyl cellulose, k-carrageenan, chitosan, and xyloglucan.
Further, the binder may be, but is not limited to, a mixture of one or more of methylcellulose, ethylcellulose, carboxymethylcellulose, cellulose acetate butyrate, and chitosan.
In a specific example, the temperature sensitive flocculation gel has carboxylate anions for complexing with cations in the fire extinguishing particles.
Further, the temperature-sensitive response temperature of the temperature-sensitive flocculation gel is 120-150 ℃.
Further, when the temperature is lower than the temperature-sensitive response temperature, the temperature-sensitive flocculation gel after complexing with cations in the fire extinguishing particles can coat the fire extinguishing particles; when the temperature is not lower than the temperature-sensitive response temperature, the temperature-sensitive flocculation gel after complexing with cations in the fire extinguishing particles can release the fire extinguishing particles.
The coolant can be heated to decompose or sublimate under the action of high temperature, and when the temperature is not lower than 600 ℃, organic acid and organic polyol which are heated to decompose or sublimate in the coolant are subjected to copolymerization reaction to generate temperature-sensitive flocculation gel. The temperature-sensitive flocculent gel has large molecular weight and is flocculent in a macroscopic sense. The temperature-sensitive flocculation gel contains a large amount of carboxylate anions and has temperature sensitivity. When the temperature is lower than the temperature-sensitive response temperature, the temperature-sensitive flocculation gel can generate intramolecular hydrogen bonds, a dense cross-linked network skeleton is formed under the action of the hydrogen bonds, and the space structure of the temperature-sensitive flocculation gel is contracted and agglomerated. When the temperature is not lower than the temperature-sensitive response temperature, intermolecular hydrogen bonds of the temperature-sensitive flocculation gel are opened, reversible space structure transformation occurs, a cross-linked network skeleton is opened, and the molecular space structure is expanded.
After the coolant is heated at high temperature to form temperature-sensitive floccule gel, in the process of spraying along with the aerosol extinguishing agent, the temperature-sensitive floccule gel adsorbs most of extinguishing particles in the aerosol extinguishing agent through complexation, and then the extinguishing particles are sprayed out of a nozzle of the aerosol extinguishing device together. In the process of spraying out and in the process of dispersing in a fire extinguishing space which does not reach a fire source position subsequently, as the temperature is gradually reduced, when the temperature is lower than the temperature-sensitive response temperature, the molecular structure of the temperature-sensitive flocculation gel is contracted and agglomerated, fire extinguishing particles are coated in the structure of the temperature-sensitive flocculation gel and enter a fire scene under the action of gravity and Brownian motion, so that strong electrolyte generated by contact reaction of the fire extinguishing particles with water and the like in the air in the process of entering the fire scene is avoided, and damage to protectors in the fire extinguishing space is reduced.
Under the high temperature effect of the fire scene, when the temperature is not lower than the temperature-sensitive response temperature, the fire extinguishing particles coated by the temperature-sensitive flocculation gel are released from the inside of the structure of the temperature-sensitive flocculation gel again, are exposed to the outside of the space structure of the temperature-sensitive flocculation gel, and participate in fire extinguishment. After the fire is extinguished, the temperature of the extinguishing space and the fire scene is reduced, the extinguishing particles are coated by the flocculent gel again, so that strong electrolyte cannot be generated by contact reaction with water, and the conductivity and corrosiveness of the aerosol extinguishing agent are effectively reduced.
An embodiment of the present invention also provides a method for preparing a coolant according to any one of the above examples, including the following steps S110 to S120.
Step S110: mixing organic acid powder and organic polyol powder.
Further, the mixing time is 15 minutes to 60 minutes. The organic acid powder and the organic polyol powder are fully and uniformly mixed.
Step S120: dissolving the binder powder in a volatile organic solvent to form a solution; adding the solution into a mixture composed of organic acid powder and organic polyol powder, uniformly mixing, sieving, and granulating.
Further, after adding the solution to the mixture of the organic acid powder and the organic polyol powder, the mixing time is 15 minutes to 60 minutes. The adhesive is fully and uniformly mixed with the organic acid and the organic polyol.
Further, the standard mesh number used for sieving before granulating is 10 mesh to 40 mesh.
Further, drying is performed after granulation. Further, the mixture is dried under the constant temperature and humidity condition that the temperature is 25 ℃ to 50 ℃ and the humidity is less than or equal to 40 percent.
It will be appreciated that the steps of forming the organic acid powder, the organic polyol powder and the binder powder include:
respectively crushing the organic acid, the organic polyol and the adhesive, sieving with a 100-200 mesh standard sieve, and drying to form dried organic acid powder, organic polyol powder and adhesive powder.

the aerosol fire extinguishing device also comprises an aerosol fire extinguishing agent, wherein the aerosol fire extinguishing agent comprises fire extinguishing particles, and the fire extinguishing particles are provided with cations which can be complexed with the temperature-sensitive flocculation gel.
It will be appreciated that aerosol fire extinguishing agents may be, but are not limited to, common K-type aerosol fire extinguishing agents and S-type aerosol fire extinguishing agents.
