preparation example Construction

[0046] Correspondingly, the embodiment of the present invention also provides a preparation method of the above-mentioned fluorine-free easily degradable additive. In one embodiment, the preparation method of the above-mentioned fluorine-free easily degradable additive comprises the following steps:

[0047] Step S01, respectively weighing the surfactant, organic solvent, anti-scalding agent, alkali metal salt and water according to the above formula;

[0048] Step S02, performing mixing treatment on the weighed surfactant, the organic solvent and the anti-scalding agent to obtain component A;

[0049] Step S03, mixing the weighed alkali metal salt and the water to obtain component B;

[0050] In step S04, the component A and the component B respectively obtained in step S02 and step S03 are mixed.

[0051] Specifically, steps S01-S04 only need to be performed at normal temperature.

[0052] Specifically, in the mixing process of steps S02-S04, each component needs to be fu...

Abstract

The invention relates to the technical field of fire extinguishing and particularly discloses a fluoride-free additive easy to degrade and a preparing method and application thereof. The fluoride-free additive easy to degrade is composed of, by weight, 1%-10% of surface active agents, 10%-20% of organic solvent, 1%-10% of anti-burning agents, 10%-20% of alkali metal salt and the balance water. According to the fluoride-free additive easy to degrade, the surface active agents, the organic solvent, the anti-burning agents and the alkali metal salt serve as the important components of the fluoride-free additive easy to degrade, the four components cooperate with one another to improve a micro fine water mist fire extinguishing environment together, in this way, the fire extinguishing effect is improved, and the phenomenon of accelerated corrosion of metal products on a fire scene after a disaster can be avoided; in addition, the fluoride-free additive easy to degrade is nontoxic, harmless and environment-friendly and can be widely applied to fine water mist fire extinguishing systems on various occasions.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing, in particular to a fluorine-free and easily degradable additive and a preparation method and application thereof. Background technique [0002] Since the United States issued the world's first design standard for water mist fire extinguishing systems (NFPA750-1996) in 1996, water mist fire extinguishing technology, as a new generation of fire extinguishing technology, has gradually become popular because of its high efficiency, stability, and cleanliness. It replaces the fire extinguishing product "Halon" and has been vigorously promoted. In August 2001, the Fire Department of the Ministry of Public Security of the People's Republic of China issued Gongxiao [2001] No. 217 document, which stipulates that high-pressure water mist can be used as a substitute for "halon" in my country. At present, the water mist inactivation technology has gradually moved towards the application stage. ...
