Problems solved by technology

However, in the field of sea fire protection, there is still a lack of better solutions
The reason is that the current anti-solvent water film-forming foam fire extinguishing agent is only suitable for mixing with fresh water for fire extinguishing, not suitable for mixing and foaming with seawater.

Abstract

The invention belongs to the field of fire extinguishing materials and relates to a foam fire extinguisher, in particular to a seawater-resistant foam fire extinguisher which comprises the following components in parts by mass: 10-12 parts of alkyl glycoside, 10-12 parts of a surfactant, 4-8 parts of xanthan gum, 2-4 parts of modified calcium carbonate powder, 1-3 parts of modified nano-silicon dioxide, 2-4 parts of 2-chlorobenzalmalononitrile, 2-3 parts of a stabilizer, 3-4 parts of a corrosion inhibitor, 4-5 parts of epoxy ether, 2-3 parts of ethylene glycol monoethyl ether and 40-60 parts of water. The seawater-resistant foam fire extinguisher provided by the invention has the characteristics of being high in foaming speed, delicate in foam and high in foam adhesion, and has a relatively good extinguishing effect on various fire disasters on the sea.

Description

technical field [0001] The invention relates to the field of fire-fighting and fire-extinguishing materials, in particular to a foam fire-extinguishing agent, in particular to a seawater-resistant foam fire-extinguishing agent. Background technique [0002] In recent years, international restrictions on the composition of fire extinguishing agents used in the field of fire protection have become increasingly stringent. This development trend makes the original commercially available foam fire extinguishing agents more pursuing their own environmental protection, versatility and high efficiency, and presents a rapid product innovation and change. However, in the field of sea fire protection, there is still a lack of better solutions. The reason is that the current anti-solvent type aqueous film-forming foam fire extinguishing agent is only suitable for mixing with fresh water for fire extinguishing, and is not suitable for mixing and foaming with seawater. In addition, seaw...
