Description

Technical Field

[0001] The invention belongs to the technical field of petrochemical water-based fire extinguishing agents, and in particular relates to a petrochemical water-based special fire extinguishing agent with fire prevention function. Background Art

[0002] With the development of society and the continuous improvement of productivity, the use and application scope of petrochemical products are increasing. As a result, the amount of oil extraction, processing and storage is increasing. Large reserves of oil and products pose huge fire hazards, so fire prevention is more important than fire extinguishing. Once a fire occurs, the burned area is huge. If the performance of the fire extinguishing agent is not high enough, it is impossible to control it. There are many categories of petrochemical products, which contain a large amount of hydrocarbon substances, especially low-carbon hydrocarbons, which are easy to gasify, flammable and explosive. The fire spreads quickly and the danger level is extremely high. Oil is very prone to fire during storage and refining. Its fire characteristics are high calorific value, large amount of fuel generated, fast spread, strong destructive power and extremely high danger factor.

[0003] However, conventional Class B fire extinguishing agents still have many disadvantages such as poor environmental protection, easy re-ignition after fire extinguishing, high cost, poor fire extinguishing performance, and inability to prevent fires. In particular, the petrochemical industry still needs a fire extinguishing agent that is highly efficient, flame retardant, easily degradable, less polluting, and does not re-ignite, and has both fire prevention and fire extinguishing functions. Therefore, a petrochemical water-based special fire extinguishing agent with fire prevention function is proposed to solve the above problems. Summary of the invention

[0004] In view of the above situation, in order to overcome the many shortcomings of the existing conventional Class B fire extinguishing agents, such as poor environmental protection, easy re-ignition after fire extinguishing, high cost, poor fire extinguishing performance, and inability to prevent fire, which makes the purification of water bodies relatively inefficient, the present invention proposes a petrochemical water-based special fire extinguishing agent with fire prevention function. Deionized water is used as the fire extinguishing agent carrier and is also the main component for forming a water film. The thickener improves the carrier performance after thickening the liquid, and is also an element for water storage and film formation. When the area where petrochemical products are stored has an out-of-control state such as product overflow, container rupture, leakage, etc., the petrochemical water-based special fire prevention and fire extinguishing agent is quickly sprayed to cover the flammable liquid, and a flame-retardant water film is formed on the surface of the flammable liquid, so as to isolate oxygen and prevent combustion, and prevent small fires from spreading and causing combustion of other containers or explosions. Technical effect of large fires.

[0005] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: The present invention provides a petrochemical water-based special fire extinguishing agent with fire prevention function, comprising the following components in parts by weight: 2.5-3.5 parts of surfactant, 1.8-2 parts of flame retardant, 3-18 parts of antifreeze agent, 1-1.3 parts of stabilizer, 2.8-3.3 parts of urea, 2-5 parts of foaming agent, 0.3-1 part of thickener, 0.3-1 part of fixative, 0.3-1 part of adsorbent, and 62.9-93 parts of deionized water.

[0006] Furthermore, the petrochemical water-based special fire extinguishing agent is prepared by the following steps:

[0007] S1. Dissolve the flame retardant in three times the weight of deionized water, stir for 30 minutes, add a certain amount of urea, and then add an equal amount of deionized water and continue stirring for 10 minutes to obtain a mixed solvent I;

[0008] S2, pouring the adsorbent, antifreeze agent and stabilizer into the remaining deionized water and stirring for 35 minutes to obtain a mixed solvent II;

[0009] S3, pouring the mixed solvent I into the mixed solvent II, then adding the foaming agent and the surfactant and stirring for 55 minutes, the reaction is completed, and the petrochemical water-based special fire extinguishing agent is obtained.

[0010] Furthermore, the surfactant is a combination of one or more of alkyl polysaccharide, alkyl polyglycoside and alkyl glucoside.

[0011] Furthermore, the main component of the flame retardant is ammonium phosphate salt, and the ammonium phosphate salt is one of diammonium phosphate and ammonium phosphate.

[0012] Furthermore, the adsorbent is CMC hydroxymethyl cellulose.

[0013] Furthermore, the stabilizer consists of diethylene glycol monobutyl ether.

[0014] Furthermore, the particle size of the urea is ≤45 μm.

[0015] Furthermore, the antifreeze agent consists of ethylene glycol.

[0016] Furthermore, the ratio of concentrated liquid to water in the petrochemical water-based special fire extinguishing agent is 1:10.

[0017] The beneficial effects of the present invention are:

[0018] 1. The petrochemical water-based special fire extinguishing agent provided by the present invention uses deionized water as a fire extinguishing agent carrier and is also the main component for forming a water film. The thickener improves the carrier performance after thickening the liquid, and is also an element for water storage and film formation. When the petrochemical product area is in an out-of-control state such as product overflow, container rupture, leakage, etc., the petrochemical water-based special fire prevention and fire extinguishing agent is quickly sprayed to cover the flammable liquid, and a flame-retardant water film is formed on the surface of the flammable liquid to cut off oxygen and prevent combustion, and a small fire will not spread and cause other containers to burn or explode.

[0019] 2. The surfactant in the present invention not only reduces the tension of water, improves the uniform dispersion ability of various agents, and improves the fluidity of the liquid so that the fire retardant quickly covers the surface of the flammable liquid, forms a protective film to isolate oxygen and combines with the foaming agent. Because the foam contains a flame retardant, a foam layer is formed on the upper side of the water film. The foam contains a flame retardant, which not only improves the isolation effect of oxygen but also has anti-burning performance. In addition, it cooperates with the flame retardant. The flame retardant is evenly dispersed in the water film-forming agent in the flame retardant to improve the flame retardancy of the water film.

[0020] 4. The antifreeze agent in the present invention can make the fire extinguishing agent adapt to the ambient temperature and adjust the dosage according to the ambient temperature, and further ensure that the agent remains in a liquid state suitable for the deployment of the spraying function.

[0021] 5. The petrochemical water-based special fire prevention and extinguishing agent in the present invention is also a highly efficient and environmentally friendly fire extinguishing agent, which can be filled in portable, cart-type, backpack fire extinguishers, can be applied to automatic sprinkler devices, and can be filled in fire trucks;

[0022] 6. The fire extinguishing agent of the present invention has good fireproof effect. After spraying the fire retardant, the flammability risk of flammable materials is greatly reduced. It is easy to degrade and environmentally friendly. Surfactants and thickeners are made of renewable biological extracts, ammonium phosphate and urea plant growth agents, and the foaming agent is fluorine-free and 100% biodegradable with organic phosphorus, and contains a small amount of easily degradable solvents.
