Abstract

The invention discloses a fire extinguishing agent. The fire extinguishing agent is characterized by comprising raw materials including, by weight part, 10 to 20 parts of tetrafluoroethane, 5 to 10 parts of aluminum sulfate, 1 to 5 parts of zinc carbonate, 1 to 5 parts of sodium bicarbonate, 50 to 80 parts of ammonium dihydrogen phosphate, 30 to 100 parts of ammonium bicarbonate, 30 to 40 parts oflyophobic white carbon black, 5 to 10 parts of azodicarbonamide and 5 to 8 parts of vinyl alcohol. The fire extinguishing agent is long in expiration date, heat resistance, electric insulation, hydrophobicity, lipophobicity, and other properties are improved, and the fire extinguishing property is high.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a fire extinguishing agent. Background technique [0002] At present, the existing foam fire extinguishing agents are easy to rot, deteriorate and are difficult to store. Contents of the invention [0003] The purpose of the present invention is to provide a fire extinguishing agent, which has a long shelf life, improved heat resistance, electrical insulation, hydrophobicity, oil repellency and other properties, and high fire extinguishing performance. [0004] The technical scheme of the present invention: a fire extinguishing agent is characterized in that it is composed of the following raw materials in parts by weight: 10-20 parts of tetrafluoroethane, 5-10 parts of aluminum sulfate, 1-5 parts of zinc carbonate, bicarbonate 1-5 parts of sodium, 50-80 parts of ammonium dihydrogen phosphate, 30-100 parts of ammonium bicarbonate, 30-40 parts of hydrophobic white car...
