Embodiment 1

[0020] Prepare the ammonium phosphate salt cold aerosol multifunctional fire extinguishing agent according to the following raw material weight ratio and steps:

[0021] 1) Get common ammonium phosphate salt powder 600kg mica 80kg ammonium sulfate 100kg clay 80kg sodium chloride 60kg white carbon black 80kg, silicone oil 6kg;

[0022] 2) After mixing, the low temperature is below 10°C and pulverized to below 2 microns;

[0023] 3) Mix the above ingredients, and dehydrate at a constant temperature of 90-130°C with hot air flow until the water content is below 0.15%;

Embodiment 2

[0025] Prepare the ammonium phosphate salt cold aerosol multifunctional fire extinguishing agent according to the following raw material weight ratio and steps:

[0026] 1. Take ordinary ammonium phosphate powder 850kg mica 20kg ammonium sulfate 10kg clay 20kg sodium chloride 60kg white carbon black 40kg silicone oil 15kg;

[0027] 2), 3) steps are identical with embodiment 1.

Embodiment 3

[0029] 1) Take 750kg of ordinary ammonium phosphate salt powder, 50kg of mica, 70kg of ammonium sulfate, 30kg of clay, 50kg of sodium chloride, 50kg of white carbon black, and 9kg of silicone oil;

[0030] 2), 3) steps are identical with embodiment 1.

Abstract

The present invention provides an ammonium phosphate salt air conditioning sol multi-purpose extinguishing agent and method for preparing. The proportioning by weight of material is common ammonium phosphate salt powder 600-850kg, mica 20-80kg, ammonium sulphate 10-100kg, carclazyte 20-80kg, sodium chloride 50-60kg, white carbon black 40-80kg, silicon oil 6-15kg; alternatively, wet-process monoammonium phosphate 700-900kg, carclazyte 20-60kg, white carbon black 40-80kg, mica 20-60kg, ammonium sulphate 10-50kg, sodium chloride 30-50kg, silicon oil 6-15kg, the granularity below 2 mu m is 90%. The invention has high extinguishment effect, and wide range; since granularity is below 2 mu m, suspension time under the state of closing and semi-closing of aerosol is above 30 min, and fire is wholly submerged, type A solid matter fire, type B liquid matter fire, type C gas matter fire and type E appliance fire are all put out, and fired by crossing barrier. type D metal fire is put out by adding sodium chloride, the degree by weight is 8-20 times of the common powder extinguishing agent, 3-5 times of the ammonium phosphate superfine powder extinguishing agent. The extinguishing agent also has low cost, energy conservation and high added value characteristics.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to an ammonium phosphate cold aerosol multifunctional fire extinguishing agent (abbreviated as ABCDE cold aerosol multifunctional fire extinguishing agent) and a preparation method thereof. Background technique [0002] 'Halon' fire extinguishing agent has played a certain role in fire fighting due to its high-efficiency fire extinguishing performance, and is widely used in fire fighting in various occasions, thus winning an important position in fire extinguishing agents. However, the development of human society has proposed a new indicator for fire extinguishing technology besides the two major indicators of fire extinguishing and personal safety, that is, the natural environment protection indicator for human survival. Since the 1980s, people have realized that halon fire extinguishing agents have a strong destructive effect on the atmospheric ozone layer, and internationa...
