Abstract
The present invention relates to an oil rapid fire-extinguishing agent which is mainly prepared from the ingredients of 1 to 5% of C6F13SO2NH(CH2)3N(CH3)CONH2, 1 to 5% of F[C(CF3)FCF2O]nC(CF3)FCONH(CH2)3NO(C2H5)2(n=1-2), 6 to 15% of coconut oil-based betaine, 2 to 5% of hydrolysis animal protein, 5 to 15% of cosolvent, 0.5 to 1% of viscosity increaser and 30 to 65% of water. Each ingredient generates synergistic effect, and the oil rapid fire-extinguishing agent has the advantages of no foam burning phenomenon, better self-sealing, high spreading speed, good afterburning resistance, stable performance after long-term placement and no corrosiveness; the fire-extinguishing agent quickly forms a sealed foam layer on an oil surface to isolate oxygen and prevent fuel from being evaporated, and quickly extinguishes oil conflagration.
Description
Technical field
The present invention relates to the quick extinguishing agent that a kind of fuel oil that is used for ground such as oil field, large-scale storage plant and gas station catches fire.
Background technology
The proportion of water is 0.9982 at 20 ℃, the proportion of crude oil 20 ℃ one be about 0.86.Oils is caught fire and can't be put out by water, and water can sink to the below of oil, and oil contacts with oxygen on the surface and burns away.The surface tension of water is 72.80mN/m in the time of 20 ℃.The surface tension of the weak solution of conventional surfactants can drop to about 20mN/m, and the surface tension of the weak solution of fc-surfactant can drop to 20mN/m even lower.Thereby the moisture film of the fc-surfactant aqueous solution can sprawl at pasta and come, and starvation puts out big fire, therefore is often used as the special-purpose extinguishing chemical of oils.
Yet simple fc-surfactant blow-off velocity is slow, is difficult to solve the problem of big fire resume combustion, as:

2The aqueous solution (concentration 0.1%) that reaches auxiliary agent is extinguishing chemical, and its surface tension is 18mN/m, with 6 liters of hand fire extinguishers, fill the extinguishing chemical of standard weights, in diameter is 1.2 meters garden iron basin, add 35 liters of 90# gasoline combustions after 1 minute, high about 3 meters of flame begins fire extinguishing again.Result of the test is that 90% control fire time was 17 seconds, and attack time is 25 seconds.After big fire was put out, the pasta foam density was inhomogeneous, and self-styled is slower.There is the high flare of a small amount of one-inch on the surface of foam top, the sign of resume combustion is arranged.

Simultaneously, the fc-surfactant molecular weight is big, solubility is little, a little less than the hydrophily, be easy to layering, makes extinguishing chemical unstable and rotten corrupt.
Summary of the invention
The object of the present invention is to provide a kind of oil fast extinguishant, its blow-off velocity is fast, and anti-resume combustion is good, and product is transparent, and evenly chemical stability is good, and is not stratified, never degenerates, and durable storage is easy to use.
For reaching above technical purpose, the invention provides following technical scheme.
