Embodiment 1

[0023] A kind of preparation method of efficient green environment-friendly fire extinguishing agent comprises the following steps:

[0024] (1) Take 4g of sodium dihydrogen phosphate dihydrate, 1.5g of ammonium bicarbonate, and 2g of sodium carbonate and mix them into an agate mortar, grind for 1 hour and then sieve to control the particle size between 200-250 mesh to obtain the first a mixture;

[0025] (2) Add 0.5g of micron or nanometer silicon dioxide to the first mixture, mix thoroughly and continue to grind for 1 hour, then sieve, and control the particle size between 300-350 mesh to obtain the second mixture;

[0026] (3) Add simethicone oil to the second mixture in an amount of 0.05ml simethicone oil per 1g of the second mixture, and then stir evenly to form the third mixture;

[0027] (4) Put the third mixture into an electric constant temperature digital display blast drying oven, set the temperature at 100°C, keep it warm for 2 hours, and then take it out.

Embodiment 2

[0029] A kind of preparation method of efficient green environment-friendly fire extinguishing agent comprises the following steps:

[0030] (1) Mix 5g of sodium dihydrogen phosphate dihydrate, 2.25g of ammonium bicarbonate, and 2.5g of sodium carbonate into an agate mortar, grind for 1.5 hours and then sieve to control the particle size between 230-270 mesh. obtain the first mixture;

[0031] (2) Add 1g of micron or nanometer silicon dioxide to the first mixture, mix thoroughly and continue to grind for 1.5h, then sieve to control the particle size between 330-370 mesh to obtain the second mixture;

[0032] (3) Add simethicone oil to the second mixture in an amount of 0.075ml simethicone oil per 1g of the second mixture, and then stir evenly to form the third mixture;

[0033] (4) Put the third mixture into an electric constant temperature digital display blast drying oven, set the temperature at 102.5°C, keep it warm for 2.5 hours and then take it out.

Embodiment 3

[0035] A kind of preparation method of efficient green environment-friendly fire extinguishing agent comprises the following steps:

[0036] (1) Mix 6g of sodium dihydrogen phosphate dihydrate, 3g of ammonium bicarbonate, and 3g of sodium carbonate into an agate mortar, grind for 2 hours and then sieve to control the particle size between 250-300 mesh to obtain the first mixture;

[0037] (2) Add 1.5g of micron or nanometer silicon dioxide to the first mixture, mix thoroughly and continue to grind for 2 hours, then sieve, and control the particle size between 350-400 mesh to obtain the second mixture;

[0038] (3) Add simethicone oil to the second mixture in an amount of 0.1ml simethicone oil per 1g of the second mixture, and then stir evenly to form the third mixture;

[0039] (4) Put the third mixture into an electric constant temperature digital display blast drying oven, set the temperature at 105°C, keep it warm for 3 hours, and then take it out.

Abstract

A preparation method for a high-efficiency and environment-friendly fire extinguishing agent comprises the following steps that, by weight, 4-6 parts of sodium dihydrogen phosphate dihydrate, 1.5-3 parts of ammonium bicarbonate and 2-3 parts of sodium carbonate are taken and mixed to be added into an agate mortar, after 1-2 hours of grinding, sieving is carried out, and particle sizes are controlled within 200-300 meshes; then, by weight, 0.5-1.5 parts of white carbon black is added, and after sufficient mixing, grinding continues to be carried out for 1-2 hours; then, sieving is carried out,the particle sizes are controlled within 300-400 meshes, simethicone is added, the adding amount of the simethicone per one weight part of a second mixture is 0.05-0.1ml, a mixture is stirred to be uniform and added into an electric constant-temperature digital readout blast air oven, the temperature is set to be 100 DEG C-105 DEG C, and after 2-3 hours of temperature keeping, the mixture is takenout. The fire extinguishing agent prepared through the method is high in efficiency and environmentally friendly.

Description

technical field [0001] The invention relates to a preparation method of a high-efficiency green and environment-friendly fire extinguishing agent. Background technique [0002] Fire has always been the enemy of mankind. From ancient times to the present, whether it is a natural fire or an accidental fire, on the one hand, it has caused a large amount of natural resources and property losses, and on the other hand, human beings have also suffered greatly. At present, all kinds of fire extinguishing agents widely used in the world have more or less deficiencies in terms of conditions of use, scope of application, environmental protection and fire extinguishing performance, and their inhibitory effect on smoke caused by fire is very limited. Halon fire extinguishing agent is the most typical representative among them. [0003] Halon fire extinguishing agent has the characteristics of high fire extinguishing efficiency, less dosage, good space submersion and chemical stability...
