The present invention relates to fire and fire extinguishing complexes, in particular liquid fire and fire extinguishing complexes, for extinguishing fire with Class A and B materials and combustible organic solvents. The active ingredient of the fire prevention and digestion complex of the present invention is an aqueous extract of various plants and vegetation.

Recently used extinguishing agents are foam, dry dry extinguishing agent, carbon dioxide extinguishing agent, carbon tetrachloride extinguishing agent and the like. These extinguishing agents are usually packaged for special fire extinguishing. Different extinguishing agents are selected depending on the nature of the ignition substance. The mechanism of action of the extinguishing agents is based on the physical principle of blocking the ignition source from air with a protective layer formed by foam, powder, or inert gas generated from the extinguishing agent.

If the fond is not relatively strong, it is effective in extinguishing small, relatively less dangerous fires by Class A and B materials. However, it is difficult to achieve the expected effect or no expected effect for a dangerous fire in a state where the wind speed is relatively strong, for example, a wind class of 6 or more, that is, the wind speed is in the range of about 10.8 to 13.8 m / s. In case of a fire caused by fuel oil, edible oil, organic solvent or flammable liquid such as oil or grease-containing material, a large amount of energy is generated due to incomplete combustion, the fire spreads very fast and the temperature of liquid surface is very high. (≧ 300 ° C.), recently used fire and extinguishing agents cannot be used to extinguish fire quickly and efficiently.

In particular, in the event of a fire in a vehicle fuel tank due to a traffic accident or a mechanical collision, the fire may ignite and rapidly spread, causing a big explosion before using a fire extinguisher, resulting in fire hazards, casualties and serious economic losses. In addition, the explosion of the fuel tank may also be caused by static sparks generated by the movement of the vehicle, and even a conventional extinguishing agent is almost useless.

In order to extinguish fire with flammable liquids such as crude oils, fuel oils, edible oils, organic solvents, and oils and grease-containing materials, various chemical fire and extinguishing agents such as halogen-substituted hydrocarbons, phosphonate compounds, inorganic compounds, etc. have been developed and Is being produced. However, these chemical fire and extinguishing agents are usually used as additives in polymer engineering materials. Among these extinguishing agents, only a few substances such as fluoro-bromo-alkanes can be used as extinguishing agents but are rarely used due to the high cost and the destruction effect of the ozone layer. Moreover, because these materials are water-insoluble, it is very difficult to produce fire and extinguishing agents using aqueous solvents.

An object of the present invention is to provide a fire- and fire-extinguishing complex using an aqueous extract of various plant and vegetation as an active ingredient, the raw material can be easily obtained and the manufacturing process is also very simple and low cost.

It is yet another object of the present invention to provide a fire and extinguishing liquid complex using water as a solvent for quickly and effectively extinguishing fires of Class A and B substances.

It is a further object of the present invention to provide a fire and extinguishing liquid complex using water as a solvent to quickly extinguish fuel tank fires in various vehicles and aircraft while eliminating the risk of explosion in fuel tanks.

It is a further object of the present invention to provide a liquid fire protection and extinguishing complex using water as a solvent to quickly and effectively extinguish flammable organic solvents, crude oil, heavy oils, oil residues, and fires of oils and grease containing materials.

It is yet another object of the present invention to provide a fire and extinguishing liquid complex using water as a solvent having good anti-ignition performance.

The fire protection performance of the fire protection and fire extinguishing composite of the present invention was measured by the apparatus shown in FIG. The apparatus includes a 20 l container of flammable oil 7 and a 20 l container 13 for fire and extinguishing composite. An oil tube (8) having a diameter of 9.2 mm is inserted from the top of the container (7) to the bottom of the container (7), and the oil injection switch (2) is installed on the top of the tube (8) at the top of the container (7). It is. The inlet of pressurized air is located on one side of the upper end of the container 7. The pressure gauge 3 is located at the top of the vessel 7. A tube 14 having a diameter of 25.4 mm is inserted from the top of the vessel 13 to the bottom of the vessel 13, the injection switch 10 is located at the top of the tube 14 and the fluid control valve 9 is injected. It is located above the switch 10. The pressurized air inlet 4 ′ is located on one side of the top of the vessel 13. The inlet 12 of the fire and extinguishing composite is located on the other side of the top of the container 13. The input gauge 3 'is also located on top of the vessel 13. The connection of the tube 14 and the oil tube 8 forms a fire and extinguishing chamber 1, on which there is a fluid-mixing zone 18. The receiver 17 is located above the fluid-mixing zone 18. The vessels 7 and 13 are both pressure vessels having an operating pressure of 1.5 MPa or more.

For the experiment, 10 liters of flammable oil and 10 liters of the fire and extinguishing composite solution of the present invention having an initial boiling point of 88 ° C. or higher and a terminal boiling point of 105 ° C. or lower were placed in containers 7 and 13, respectively. The pressures in the vessels 7 and 13 were adjusted to 0.46 to 0.5 MPa and 0.55 to 0.60 MPa, respectively. Then turn on the oil spray switch (2) and ignite the sprayed oil with the igniter. The height of the blowout flame may be higher than 8 meters. When the flame height is at its maximum, the injection switch 10 is opened. The volume of the flammable oil, and the fire and extinguishing complex, is adjusted in a 0.5: 1 ratio with a fluid control valve. Open the injection switch 10 and record the time until the flame is extinguished completely. This experiment was repeated twice to set the average value of the two experiments as the fire protection performance.

2. Fire and extinguishing performance

The distribution of flammable oils, oil trays and oil trays is identical to the standard method of ISO 7202. The fire and extinguishing complex of the present invention was placed in a 3 kg fire extinguisher for the experiment. Ignite flammable oil, burn for 2 minutes, then open the valve of the container containing the fire and extinguishing complex and spray the fire and extinguish complex at a flow rate of 0.6 l / m ² to the fired oil tray. Record the time from the start of the spray until the fire is completely extinguished. This experiment was repeated twice to give the average value of the two experiments as fire and extinguishing performance.

3. Anti-ignition performance

For the fire and extinguishing performance test, 200 ml of the mixture of the fire and extinguishing complex and the combustible oil of the receiver 17 obtained in the 250 ml graduated cylinder was left to stand for about 15 minutes. It is then placed in the open flash point tester of model SYB 1001 and aligned with the initial gridline. The flame height in the printer is adjusted to about 8-9 mm and ignited at about 14-15 mm above the surface of the mixture liquid to observe the results.

The fire- and fire-extinguishing complex of the present invention is at least one selected from the group consisting of sapindacea, composita, crucepera, leguminosa, endosperm of Ulmasea, phytolacase and cottonseed plants. Plant and herbaceous aqueous extracts were used as active ingredients and at least one surfactant was mixed with this aqueous extract. Thus a synergistic fire and extinguishing effect is achieved. The complex not only physically fires and extinguishs by isolating flammable substances such as oils from the air, but also chemically fires and extinguishes by interrupting the transmission of the combustion chain.

According to the present invention, plants and herbaceous plants selected from the group consisting of saffindacea, composita, crucefera, leguminosa, endosperm of Ulmasea, phytolacase and cottonseed plants are halogenated derivatives. Have more fire and extinguishing agents such as Its aqueous extract also contains substances with fire and digestive action. When using the complex of the present invention to extinguish fire, the halogenated derivative contained therein decomposes under high temperature to produce halogen free radicals X, and the halogen free radicals formed rapidly combine with hydrogen free radicals to form HX. then the HO produced during combustion of the combustible material ^-, HOO ^- and combines rapidly.

Thus, delivery of combustion chains or flame dispersion will be slowed or stopped. The aqueous extract also contains a large amount of phosphate and phosphate esters, which are converted to metaphosphates at high temperatures and the formed metaphosphates are then converted into safe polymer forms, whereby a protective film is formed around the combustibles so that the combustibles come into contact with oxygen. Will be prevented. Therefore, the spread of fire can be prevented. In addition, the inorganic salts and silicates present in the aqueous extract also form an isolation and barrier around the combustible material. The elastic potassium contained in the aqueous extract, which comes from the vegetation, continues to produce carbon dioxide by pyrolysis under high temperature, and the produced carbon dioxide forms an inert gas film around the combustible material and has excellent fire protection. Moreover, this aqueous extract contains not only proteins but also large amounts of various polysaccharides, celluloses, fatty acids. They can be mixed with surfactants to form complex emulsifiers with good emulsifying effects. This complex emulsifier is an excellent extinguishing foam.

When spraying the composite of the present invention on the burning combustible liquid surface, it spreads over the burning combustible liquid surface, disperses in the combustible liquid and emulsifies the combustible liquid to form an extremely small oil emulsion in water. During the dispersion of the composite of the present invention and the emulsification of the flammable liquid, the flammable liquid is simultaneously denatured to form a protective layer around the oil bead, the digestion layer, the micelle layer and the gel layer, preventing the oil from contacting oxygen. Aqueous extracts of plants and vegetation contain large amounts of salts, sugars, celluloses and proteins, which are formed to form membranes around flammable liquids at high temperatures and have good flow, shielding and fire resistance. Therefore, this membrane effectively blocks the oxygen in the combustion material, prevents the fire from spreading and extinguish the fire quickly. The composites of the present invention also denature flammable materials and thus have good anti-ignition performance.

When the composite of the present invention is sprayed onto a burning solid material, such as wood, cottonseed and oil-containing cotton fabric, it penetrates into the internal fibrous tissue of the fugitive solid material and forms a uniform fire barrier on the surface of the combustible material. Therefore, it is possible to extinguish the fire quickly.

Due to the above excellent properties and synergistic fire and digestive synergistic effects, the composites of the present invention can be widely used to extinguish a variety of fires except fires by electricity and metals. In particular, various textile products such as crude oil such as gasoline, kerosene and diesel oil, various chemicals except edible oils, organic solvents, metals, grease and oil-containing materials such as oil-containing cotton fabrics, liquid flammable substances such as wood Suitable for extinguishing fires by The composite of the present invention can also be used to extinguish a fire caused by the combustion of a solid material or a fire in a structure.

The fire and extinguishing composite of the present invention, in combination with special equipment mounted on fuel tanks of various vehicles, is the most effective extinguishing agent for extinguishing fires generated in fuel tanks of vehicles.

By employing the complex of the present invention, the digestibility is higher and better than when employing existing extinguishing agents. In general, it takes about 1 to 5 seconds to completely extinguish a fire. Compared to the expensive fluorobrodoalkane extinguishing agents such as 1211, 1202 and 1301, the extinguishing effect of the complex of the present invention is comparable to these and the cost is much lower. Compared to the widely used trifluorobromethane extinguishing agent, the composite of the present invention is slightly superior in preventing explosion and extinguishing. In addition, the composite of the present invention does not contaminate air when used.

The plant selected for producing the complex of the present invention is very abundant, its cost is low, its manufacturing process and apparatus is very simple, and its cost is very low, which is about one fifth to one tenth of the cost of the existing extinguishing agent. .
