Abstract

The invention discloses a fire extinguishing medium suitable for a foam water mist fire extinguishing system and a preparation method of the fire extinguishing medium. The fire extinguishing medium suitable for a foam water mist fire extinguishing system comprises the following raw materials in percentage by mass: 2-5% of a fluorocarbon surfactant, 10-20% of a foaming agent, 3-20% of a wrapping emulsifier, 3-10% of a foam stabilizer, 5-20% of a cooling flame retardant, 0-35% of an antifreeze agent and the balance of water. The product keeps the foam fire extinguishing characteristic, the fire extinguishing performance reaches the IA level under the standard of a foam fire extinguishing agent GB15308-2006, and the product has good fire control, fire extinguishing and burning resistance for B-type non-polar fire disasters; the fire extinguishing medium does not contain persistent pollutants such as PFOS / PFOA, and can be naturally degraded in the environment; and an ionic antifreeze agent is used, the lowest use temperature is 0-30 DEG C, and the ionic antifreeze agent can be mixed with seawater / fresh water and is suitable for seaborne and coastal areas.

Description

technical field [0001] The invention belongs to the technical field of non-polar liquid fire extinguishing medium, and in particular relates to a fire extinguishing medium suitable for a foam fine water mist fire extinguishing system and a preparation method thereof. Background technique [0002] Foam water mist fire extinguishing system is a new high-efficiency fire extinguishing technology. This technology uses pumps to mix water and foam stock solution in an appropriate proportion, and then sprays them through the water mist nozzle, and decomposes into smaller droplets under higher pressure. Put out the fire. The foam water mist fire extinguishing system combines the fire extinguishing and anti-burn characteristics of the foam fire extinguishing system with the cooling and suffocation advantages of the water mist fire extinguishing system, and has gradually attracted people's attention in recent years. [0003] In order to solve the fire problem of large oil-filled equip...
