EFFICIENT AND ENVIRONMENTALLY-FRIENDLY FIRE EXTINGUISHING AGENT AND PREPARATION METHOD THEREFOR

摘要

Disclosed are an efficient and environmentally-friendly fire extinguishing agent and a preparation method therefor. The preparation method comprises: thoroughly grinding and mixing sodium dihydrogen phosphate, ammonium hydrogencarbonate, and a pulverization aid; adding white carbon black, and thoroughly grinding and mixing the mixture; and adding silicone oil, stirring the same while heating, and maintaining a constant temperature for a period of time to obtain a silicone oil film-coated white carbon black fire extinguishing agent. The fire extinguishing agent prepared by the method has remarkably improved fire extinguishing performance and excellent fire extinguishing effects, with a fire extinguishing efficiency double that of conventional dry powder fire extinguishing agents or greater, and is superior to other fire extinguishing agents currently on the market in moisture proof, anti-caking, and anti-afterburning properties, and environmental friendliness. The fire extinguishing agent balances high fire extinguishing efficiency, a wide application range, environmental protection, and economic benefits, and has good market potential and development prospects.
