Abstract

The invention discloses an ABC dry powder fire-extinguishing agent which is prepared from the following raw materials in parts by weight: 124-140 parts of an alkaline residue, 67-84 parts of potassium sulfate, 45-60 parts of sodium oxalate, 12-17 parts of marl, 15-20 parts of magnesium carbonate powder, 8-11 parts of silicon oil, 3-7 parts of polybutylene, 11-16 parts of ammonium phosphate, 15-20 parts of chlorinated rubber, 16-19 parts of stannic oxide and 8-14 parts of silicon nitride. The ABC dry powder fire-extinguishing agent provided by the invention has the excellent effects of being good in using effect and strong in fire-extinguishing capability, can be used for extinguishing large-area oil pool fire and flowing fire, and is high in extinguishing efficiency, strong in moisture resistance and relatively high in anti-refiring performance.

Description

technical field [0001] The invention belongs to the field of dry powder fire extinguishing agents, in particular to an ABC dry powder fire extinguishing agent and a preparation method thereof. Background technique [0002] With the implementation of the national energy security strategy and the rapid development of the economy and society, in order to ensure my country's energy security and promote the sustainable development of my country's economy, the super-large oil tank will become an inevitable trend of development, and the potential large-area oil pool The risk of fire and flowing fire fire accidents is also increasing. Once the oil tank fires, the damage will be huge. The use of fire extinguishing agents plays a key role in fire fighting in tank farms. Fire extinguishing agent refers to the substance that can effectively destroy the burning conditions and stop the burning. According to its state characteristics, it can be divided into three categories: liquid fire e...
