Abstract

The invention relates to the technical field of fire extinguishing agents, in particular to a fire extinguishing agent composition, and a preparation method and application thereof. The fire extinguishing agent composition comprises an organic silicon surfactant, a hydrocarbon surfactant, an organic cosolvent, a foam additive and the like. The foam extinguishing agent has main advantages of not containing a fluorocarbon surfactant, and a polyether modified polysiloxane type organic silicon surfactant and / or a polyether trisiloxane organic silicon surfactant are / is used; on the basis of environmental protection, a compound of an anionic hydrocarbon surfactant, a nonionic hydrocarbon surfactant and an amphoteric hydrocarbon surfactant is adopted for compounding, so that better foam performance and fire extinguishing performance can be achieved; through joint adjustment and dosage matching of multiple components, low surface tension, good foaming performance and foam stabilizing performance and efficient fire extinguishing performance are achieved, and the defect that foaming performance and foam stabilizing performance of an organosilicon surfactant is relatively poor is overcome. .The fire extinguishing agent composition can achieve spreading boundary on an oil surface, can be degraded easily, is environmentally friendly, and is often applied to extinguishing oil fire.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a fluorine-free, environment-friendly and high-efficiency aqueous film-forming foam fire extinguishing agent composition and its preparation and application. Background technique [0002] Foam fire extinguishing agent is a commonly used fire extinguishing agent for fire control. The main component of traditional aqueous film-forming foam fire extinguishing agent is fluorocarbon surfactant, which can significantly reduce the surface tension, so that the fire extinguishing agent can use the "liquid phase injection" method to extinguish large-scale fire extinguishing agents. Oil product storage tank fires can also be used in combination with dry powder fire extinguishing agents. The fire extinguishing speed is one-third faster than that of protein foam fire extinguishing agents, but it is difficult to degrade in the environment after use; among them, fluorine-contai...
