The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The application provides a fire extinguishing agent based on a C4 twin type fluorine surfactant, which comprises the following components in percentage by mass: 0.2 to 1.0 percent of C4 twin-type fluorine surfactant, 1.0 to 2.0 percent of hydrocarbon surfactant, 0.2 to 1.0 percent of thickening agent, 3.0 to 5.0 percent of flame retardant, 0.01 to 0.05 percent of buffering agent and the balance of water, wherein the fluorine surfactant is the twin-type fluorine surfactant with 4 carbon fluorocarbon chain lengths and has a structure shown in a formula (I),
a formula (I);
wherein n is a positive integer having a value in the range of 2 to 6.
The combustion type of the lithium battery fire disaster has the characteristics of A, B, C, D and E type fires, and the performance of the fire extinguishing agent is required to be capable of coping with various characteristics of the lithium battery fire disaster; by adopting the scheme, the C4 twin type fluorine surfactant and the hydrocarbon surfactant are dissolved in water, the surface/interface tension of water is reduced, the permeability is improved, the aqueous solution can spread spontaneously on the surfaces of the electrolyte and the battery shell, and meanwhile, the aqueous solution can easily enter the lithium battery to play a role, so that the internal temperature of the battery is effectively reduced.
For the water-based fire extinguishing agent, the lithium battery has electric shock danger in the fire fighting process, the resistivity directly concerns the safety of the lithium battery in the fire fighting process, and the existing water-based fire extinguishing agent does not consider the resistivity problem.
Preferably, the hydrocarbon surfactant, the thickening agent, the flame retardant and the buffering agent are all nonionic compounds; by adopting the non-ionic structure of the hydrocarbon surfactant, the thickening agent, the flame retardant and the buffering agent, the resistivity of the fire extinguishing agent aqueous solution can be improved, and the electric shock hazard in the lithium battery fire fighting process can be effectively solved.
Specifically, in consideration of the interfacial activity of the hydrocarbon surfactant, the compounding capability with the C4 twin-type fluorine surfactant, the viscosity and the foaming capability, the hydrocarbon surfactant is one or more of castor oil polyoxyethylene ether, alkyl glucoside and dodecyl amine oxide; the hydrocarbon surfactants are all nonionic, and can improve the rheological property of the aqueous solution by being compounded with the C4 twin fluorine surfactant, assist in reducing the surface/interface tension of the aqueous solution, improve the affinity to the surface of a battery shell (plastic) and improve the resistivity of the fire extinguishing agent; in addition, these hydrocarbon surfactants have a low foaming capacity, ensuring permeability of aqueous solutions.
As an optional scheme, a tween (or polysorbate) surfactant and a C4 twin type fluorine surfactant can be compounded, and the surfactant is non-toxic and non-irritant; the specific selection type is Tween-40, tween-60, tween-80 and the like.
Specifically, the thickener is one or more of xanthan gum, guar gum, pectin and carboxymethyl cellulose; the use of the thickening agent can prolong the attachment time of the fire extinguishing agent aqueous solution on the surface of the lithium battery and improve the cooling effect.
Specifically, considering the dispersibility (easy dispersion) during the mixing process of the flame retardant and the stability (no delamination and no sedimentation) after mixing, the flame retardant is one or more of phosphate flame retardants such as triphenyl phosphate, tributyl phosphate and melamine phosphate; the flame retardant can flow along with the solution and cover the surface of the lithium battery, so that the occurrence rate of re-ignition is reduced.
Of course, alternative embodiments of flame retardants are possible, and phosphite based flame retardants may also be used.
Specifically, the buffer is a tris aqueous solution, wherein tris is a non-electrolyte amide, can adjust the PH of the diluent, and has the advantages of stable quality and long storage time.
When the fire extinguishing agent extinguishes open fire of the lithium battery, water in the fire extinguishing agent can react with metal lithium to obtain lithium hydroxide, the lithium hydroxide further reacts with carbon dioxide generated in combustion to obtain lithium carbonate, and the lithium hydroxide and the lithium carbonate are stable at room temperature and high temperature, so that the possibility of re-combustion is fundamentally avoided.
The present invention will be described in further detail with reference to several specific examples, but the present invention is not limited to the descriptions in the following.
