Abstract

The general multifunctional foam fire-extinguishing agent consists of plant protein 0.8-30 wt%, sugar 0.8-30 wt%, hydrocarbon surfactant 1-12 wt%, fluoric surfactant 0.1-5 wt% and additive 5-20 wt%, except water. The general multifunctional foam fire-extinguishing agent may be used to extinguish fire of alcohol and other polar chemical matter and/or light oil, heavy oil and other non-polar chemical matter. The general multifunctional foam fire-extinguishing agent contains no corrosive chemical matter, and has self-cleaning property, capacity of prolonging the service life of the fire-extinguishing equipment, no toxicity and no harm to human body and no environmental pollution.

Description

technical field [0001] The invention relates to a foam fire extinguishing agent and a preparation method thereof, in particular to a general-purpose multifunctional foam fire extinguishing agent composed of vegetable protein, a hydrocarbon surfactant and a fluorosurfactant and a preparation method thereof. Background technique [0002] Oil is the "blood of industry", an important strategic resource that supports economic development and national defense modernization, and is related to national security and stability. However, as we all know, oil is non-renewable, and replacing oil with new energy is an inevitable choice for scientific development. In order to save energy, some provinces and cities in my country have been steadily promoting alcohol gasoline instead of gasoline according to the national strategic plan, and are further expanding. With the in-depth advancement of this national strategic initiative, the fire safety and security work has f...
