Description
Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to a novel clean and efficient fluorine-containing gas fire extinguishing agent composition.
Background
Halon extinguishing agents represented by halons 1301 and 1211 are widely used in various places due to their excellent extinguishing ability. The excellent fire extinguishing capability is because Br and Cl free radicals in the halon fire extinguishing agent can capture hydrogen free radicals and hydroxyl free radicals in a fire scene and inhibit chain reaction in combustion, so that the aim of extinguishing fire is fulfilled. However, it has been found that halon extinguishing agents, due to their rather long life span in the atmosphere, reach the stratosphere of the atmosphere after being released into the atmosphere, and generate br·cl·radicals after being exposed to short-wave ultraviolet radiation, which deplete ozone by a chain reaction, each free br·or cl·radical destroying tens of thousands of ozone molecules. Thus a series of treaties and regulations prohibit the production of halon extinguishing agents and halon extinguishing agents in the remaining locations will be replaced entirely except for individual special locations where temporary use of halon extinguishing agents is permitted. After the halon extinguishing agent exits the market, developing the halon alternative extinguishing agent becomes a hot spot problem in the technical field of fire protection.
However, a range of subsequently developed fire extinguishing agents have various problems. For example, saturated halogenated hydrocarbons are stable in chemical properties at normal temperature, are difficult to degrade in the atmosphere, have long life time (ALT) and strong Global Warming Potential (GWP) or higher Ozone Depletion Potential (ODP), and do not meet the requirements of the novel clean and efficient fire extinguishing gas on environmental friendliness; although the hydro fluoroolefin containing only fluorine element has improved reactivity with OH free radical due to the existence of carbon-carbon double bond, the fire extinguishing performance is poor. On the other hand, the fire extinguishing ability of hydrofluoroolefins is positively correlated with the number of fluorine atoms contained therein, which leads to the formation of large amounts of HF in the fire, resulting in enhanced corrosiveness of the extinguishing agent. The ODP value of the halogenated olefin containing chlorine and bromine is not completely equal to zero, the environment-friendly requirement is not met, the boiling point of the fire extinguishing agent can be improved by introducing the chlorine and bromine, and the spreadability of the gas fire extinguishing agent is reduced.
Therefore, the novel clean and efficient chemical fire extinguishing agent cannot meet the comprehensive requirements of fire extinguishing performance, environmental protection performance and the like by singly using any substance, and a proper chemical fire extinguishing agent is required to be selected for compounding, so that the environmental friendliness of the compound chemical gas fire extinguishing agent is improved and the corrosiveness of the compound chemical gas fire extinguishing agent in a fire scene is reduced on the premise of ensuring that the diffusion performance and the fire extinguishing performance of the compound chemical gas fire extinguishing agent are not reduced, and the compound chemical gas fire extinguishing agent with excellent comprehensive performance is formed.
Disclosure of Invention
In view of the above, the invention provides a series of clean chemical gas fire extinguishing agent compositions which are easy to store, low in cost and have market application prospects, aiming at the problem that the existing single chemical fire extinguishing agent cannot meet the requirements of fire extinguishing performance, environmental protection performance, low corrosiveness, low cost, easy storage and the like. The gas fire extinguishing agent composition takes hydrofluoroolefin as a main material, is assisted with other chemical gas fire extinguishing agents with low boiling points and equal or better fire extinguishing performance, can reduce the corrosiveness of the hydrofluoroolefin in fire products, and has small influence on the boiling point and the fire extinguishing performance of the compound chemical gas fire extinguishing agent.

Other hydrofluoroalkane/alkene, hydrochlorofluoroalkane/alkene and hydrofluorobromoalkane/alkene are taken as fire extinguishing auxiliary agents, and the weight percentage of the hydrofluoroalkane/alkene is 20-45% of the mass of the composition. Wherein the other hydrofluoroalkane/alkene, hydrochlorofluoroalkane/alkene, hydrofluorobromoalkane/alkene includes, but is not limited to, one or more combinations of pentafluoroethane, hexafluoroethane, hexafluoropropane, heptafluoropropane, octafluoropropane, hexafluoropropylene, heptafluorobutene, octafluorobutene, chlorotetrafluoroethane, dichlorotrifluoroethane, chloroheptafluoropropane, dichlorohexafluoropropane, chlorotrifluoropropene, dichlorotrifluoropropene, bromotrifluoroethane, bromotetrafluoroethane, bromoheptafluoropropane, bromohexafluoropropane, bromotrifluoropropene, bromotetrafluoropropene, bromopentafluoropropene.
Filling and sealing the mixture into the same container, and filling inert gas to 1.0-2.5 MPa, wherein the specific filling and sealing pressure refers to the container material, structure, pressure-bearing characteristic and application environment so as to ensure the rapid and complete release of the gas extinguishing agent composition.

Other modifications of the invention which do not involve the inventive work, as would occur to those skilled in the art in light of the foregoing teachings, are also considered to be within the scope of the invention.
Comparative example 1
Novel clean and high-efficiency fluorine-containing gas fire extinguishing agent composition: the mixed gas fire extinguishing concentration under different mass ratios is tested by using HFO-1336mzz (Z) and nitrogen as a mixture and adopting a standard beaker method, and the experimental conditions are the same.
Comparative example 2
Novel clean and high-efficiency fluorine-containing gas fire extinguishing agent composition: the mixed gas fire extinguishing concentration under different mass ratios is tested by using HFO-1336mzz (E) and nitrogen as a mixture and adopting a standard beaker method, and the experimental conditions are the same.
According to the invention, the synergistic factor S is used for representing the synergistic fire extinguishing effect of the mixed fire extinguishing medium, and if the synergistic factor S is equal to 1, the synergistic fire extinguishing effect of the chemical gas fire extinguishing agent composition is shown; if the synergistic factor S is equal to or greater than 1, it is indicated that there is no synergistic or negative synergistic effect in the chemical gas fire extinguishing agent composition.
The cofactor S is defined as follows:
wherein n is 1 : the molar amount of substance 1 in the gaseous extinguishing agent composition required to extinguish a flame, in mol; n is n 2 : the molar amount of substance 2 in the gaseous extinguishing agent composition required to extinguish the flame, in mol;the molar amount of substance 1 required to extinguish a flame is used alone in mol; />The molar amount of substance 2 required to extinguish the flame is used alone in mol. The formula can replace all mol by volume fraction or mole fraction, and the calculation result is unchanged.
The experimental results of example 1, comparative example 1, example 2 and comparative example 2 are respectively referred to tables 1 to 4.
From the experimental results in tables 1 and 2, it can be seen that cis-1, 4-hexafluoro-2-butene (HFO-1336 mzz (Z)) can form good positive synergistic fire extinguishing effect with octafluoropropane, and the optimal mass ratio is about 55:45; whereas cis-1, 4-hexafluoro-2-butene (HFO-1336 mzz (Z)) mixed with nitrogen exhibits a negative synergistic fire extinguishing effect, indicating that nitrogen is only suitable as a propellant gas.

TABLE 2 fire extinguishing concentration and cofactor for HFO-1336mzz (Z)/nitrogen gas mixtures
From the experimental results in tables 3 and 4, it can be seen that trans-1, 4-hexafluoro-2-butene (1336 mzz (E)) can form a good positive synergistic fire extinguishing effect with hexafluoropropane, and the optimal mass ratio is about 80:20; trans-1, 4-hexafluoro-2-butene (1336 mzz (E)) can also produce a weaker positive synergistic fire extinguishing effect when mixed with nitrogen, but nitrogen is more suitable as a propellant gas because of its too high fire extinguishing concentration.
