Abstract

The invention provides a preparation method of an ABC dry powder extinguishing agent. The preparation method comprises the steps that raw materials including, by weight, 50-80 parts of monoammonium phosphate, 8-20 parts of ammonium sulfate, 5-15 parts of carbon nanofibres, 1-5 parts of mica, 1-5 parts of silicone oil, 1-5 parts of tetrafluoroboric acid pyrrolizidine spiro cyclic quaternary ammonium salt, 0.1-1 part of methylcyclopentadienyl manganese tricarbonyl, 0.01-0.1 part of chloride(indenyl)bi(triphenylphosphine)ruthenium(II), 0.01-0.1 part of cerium stabilized zirconia beads and 1-5 parts of a coupling agent are mixed, specifically, the total weight parts are 100; silicone oil is sprayed into the mixture, and a crude product is obtained; and the crude product is smashed and dried, and accordingly the ABC dry powder extinguishing agent is obtained.

Description

technical field [0001] The invention relates to a preparation method of a dry powder fire extinguishing agent, in particular to a preparation method of an ABC dry powder fire extinguishing agent. Background technique [0002] Dry powder fire extinguishing agent, the product that is used more and has better effect at present is fire-fighting dry powder. Its main raw material is ammonium phosphate, which is easy to absorb water and agglomerate, which is not conducive to the use and storage of dry powder. In order to extend the shelf life of the dry powder and make it easy to store, it is usually achieved through a siliconization process, that is, a layer of silicone oil is coated on the surface of the dry powder to isolate the contact between water and the dry powder. The existing dry powder containing ammonium phosphate with a mass fraction of 80%-85% uses the traditional ABC process to mix raw materials and auxiliary materials together for silicification. The dry powder prod...
