Abstract

The invention relates to a dedicated edible oil fire extinguishing agent and a preparation method thereof and belongs to the field of fire technology. The dedicated edible oil fire extinguishing agent comprises the following components: 10-20% of bicarbonate, 5-10% of ferrous oxide, 5-10% of silicate, 1-5% of an absorbent, 1-2% of a surfactant, 0.1-0.5% of gas, 0.1-0.5% of an emulgator and 52-77.8% of water. The invention provides the dedicated edible oil fire extinguishing agent and the preparation method thereof. The dedicated edible oil fire extinguishing agent is low in cost and toxicity, stable in structure and excellent in fire extinguishing performance to edible oil.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a special fire extinguishing agent for edible oil and a preparation method thereof. Background technique [0002] Cooking oil fires are one of the more difficult types of fires to control. Because of its unique fire characteristics, edible oil fires have been suggested as a new class of fires. In ISO3941-2007 "Fire Classification" and BSEN2-1992 "Fire Classification", edible oil fires are named as Class F fires, and in NFPA10-2007 "Portable Fire Extinguishers" and UL711-2004 "Fire Extinguisher Classification and Fire Extinguishing Test" Classified as a Class K fire. [0003] The main component of animal and vegetable oil is triglyceride of saturated and unsaturated fatty acids, its density is generally 0.95-0.98g / ml, insoluble in water, and the flash point of edible oil is generally above 300°C, which is obviously higher than that of general fuel and lubrication Theref...
