preparation example Construction

[0061] An embodiment of the present invention also provides a method for preparing a coolant as in any of the above examples, including the following steps S110 to S120.

[0062] Step S110: mixing organic acid powder and organic polyol powder.

[0063] Further, the mixing time is 15 minutes to 60 minutes. Mix organic acid powder and organic polyol powder well and evenly.

[0064] Step S120: Dissolving the binder powder in a volatile organic solvent to form a solution; adding the solution to the mixture consisting of organic acid powder and organic polyol powder, mixing evenly, sieving, and granulating.

[0065] Further, after the solution is added to the mixture composed of the organic acid powder and the organic polyol powder, the mixing time is 15 minutes to 60 minutes. Make the binder fully mix with organic acid and organic polyhydric alcohol.

[0066] Further, the standard mesh size used for sieving before granulation is 10 mesh to 40 mesh.

[0067] Furthermore, drying...

Embodiment 1

[0077] 1. Pretreatment: The raw materials furoic acid, 4-methylcinnamic acid, cinnamyl alcohol and carboxymethyl cellulose are pulverized respectively, passed through a 200-mesh standard sieve after pulverization, and then the raw materials are dried.

[0078] 2. Coolant preparation:

[0079] (1) The raw material after pretreatment is weighed by mass percentage, 15% furoic acid, 40% 4-methyl cinnamic acid, 40% cinnamyl alcohol and 5% carboxymethyl cellulose.

[0080] (2) Stir and mix the furoic acid, 4-methylcinnamic acid and cinnamyl alcohol weighed in step (1) in a powder mixer for 30 minutes, and transfer the powder mixture to a wet material mixer after the stirring is completed.

[0081] (3) The carboxymethyl cellulose taken by step (1) is dissolved in ethanol, the carboxymethyl cellulose is completely dissolved to form a solution, and the solution is added to the wet material mixer of step (2) with furoic acid, Mix 4-methylcinnamic acid and cinnamyl alcohol, stir for 15 ...

Embodiment 2

[0084] 1. Pretreatment: The raw materials behenic acid, terephthalic acid, pinacol, and methyl cellulose are pulverized separately, passed through a 200-mesh standard sieve after pulverization, and then the raw materials are dried.

[0085] 2. Coolant preparation:

[0086] (1) The raw materials after pretreatment were weighed by mass percentage, including 10% behenic acid, 45% terephthalic acid, 40% pinacol and 5% methylcellulose.

[0087] (2) Stir and mix the behenic acid, terephthalic acid, and pinacol in the powder mixer for 35 minutes in the step (1), and transfer the powder mixture to the wet material mixer after the stirring is completed.

[0088] (3) Dissolve the methyl cellulose taken by step (1) in ethanol to dissolve the methyl cellulose completely to form a solution, add the solution to the wet material mixer of step (2) with behenic acid, Mix phthalic acid and pinacol, stir for 20 minutes to make the mixture evenly mixed, then transfer the mixture to a granulator ...

Abstract

The invention relates to a coolant which comprises the following components in percentage by mass: 30%-70% of organic acid, 15%-65% of organic polyol and 1%-15% of an adhesive, the organic acid, the organic polyol and the adhesive are all in a solid state at normal temperature; the cooling agent is used for forming temperature-sensitive flocculating gel which can be complexed with fire extinguishing particles when the temperature is greater than or equal to 600 DEG C. The cooling agent can be heated to decompose or sublimate under the action of high temperature, on one hand, heat is absorbed in the decomposition or sublimation process, the temperature of a nozzle of the aerosol fire extinguishing device can be effectively reduced, on the other hand, temperature-sensitive flocculating gel is generated through heating decomposition or sublimation, and when the temperature of the temperature-sensitive flocculating gel is lower than the temperature-sensitive response temperature, the temperature-sensitive flocculating gel can be effectively reduced. The fire-extinguishing particles can be coated to prevent the fire-extinguishing particles from being in contact with water in air to generate strong electrolyte to cause secondary damage to a protection object, and the temperature-sensitive flocculating gel can release the fire-extinguishing particles to extinguish fire when the temperature is higher than the temperature-sensitive response temperature.

Description

technical field [0001] The invention relates to the technical field of fire fighting and fire extinguishing, in particular to a coolant and a preparation method thereof, a temperature-sensitive flocculation gel, and an aerosol fire extinguishing device. Background technique [0002] Fire extinguishers are important fire-fighting equipment. Common fire extinguishers mainly include dry powder fire extinguishers, carbon dioxide fire extinguishers, water fire extinguishers, and portable aerosol fire extinguishers. Among them, portable aerosol fire extinguishers have the advantages of high fire extinguishing efficiency, non-toxic and harmless, and less residue after fire extinguishing. , Widely used in various places such as industrial and mining enterprises, commercial hotels, outdoor furniture, library files, computer rooms, etc. [0003] The aerosol fire extinguishing agent and coolant are important components of the aerosol fire extinguishing device. The aerosol fire extingui...
