Description

Liquid extinguishing agent composition and method for preparing the same {COMPOSITION OF LIQUID FIRE EXTINGUISHING AND MANUFACTURING AND METHOD OF IT}

The present invention forms a surfactant micelle by dissolving or dispersing the surfactant in water, and dispersing sodium silicate on the outer wall of the micelle thus formed to prepare a fire extinguishing agent composition. It relates to a composition and a method for preparing the same.

In general, fires are classified into Class A fires, Class B fires, and Class C fires, and may be classified into more subdivisions, including class D fires including magnesium.

In the case of the Class A fire, a method of cooling and extinguishing the combustible material below the ignition point using an aqueous extinguishing agent is mainly used, but it is generally possible to extinguish using all extinguishing agents.

The B-class fire is a fire caused by oil, etc., so that extinguishing is possible by blocking contact between oxygen and a flammable substance, and thus extinguishing is possible by blocking contact with oxygen by using carbon dioxide, halon, foam, and the like.

In addition, the Class C fire is a fire caused by electricity and can be extinguished by blocking contact with oxygen. It is used for extinguishing Class C fires because it is free in powder form. Carbon dioxide, halon, foam, powder, etc. are used.

Among the fire extinguishing agents for the various types of fires, water is used in various ways because of its low safety and low cost, and a high temperature drop due to high specific heat. In particular, as water is used during combustion of flammable materials, It is possible to remove a large amount of calories, thereby enabling digestion.

However, when water is used in an oil fire, the dispersion of oil is promoted and the ignition point has a disadvantage of being diffused, and as a supplement, a surfactant and the like are used together to solve such a disadvantage. In addition, a compound for suppressing freezing occurring in water at a low temperature and lowering a freezing point for easy storage is used.

Among the many fire extinguishing agents, the best fire extinguishing agent is Halon based on performance, storage and automatic spraying. In the case of Halon, fire extinguishing is completely achieved by completely blocking fire point with oxygen due to higher density than air, and it can be used for both ABC class. However, in the case of the Halon series having such excellent characteristics, its production has been discontinued at present due to the destruction of the ozone layer and the global greenhouse effect, and some stocks are kept in petrochemical plants.

Therefore, the demand for a fire extinguishing agent having a strong extinguishing power such as Halon is very large, and although the performance is lower than that of Halon recently, a fire extinguishing agent having a strong effect on oil fires has been developed and distributed, but due to adverse environmental effects This too is stopped.

Recently, the fire extinguishing agent is the carbon dioxide, which can be sprayed by the spraying system, has the advantage that there is no environmental impact and harmless to the human body. However, since the difference in density with the air is not large, there is a problem of reducing the extinguishing power due to diffusion. Therefore, a small fire ignites a strong fire extinguishing power, but a large ignition point reaches a limit.

In addition, in the case of powder fire extinguishing agent it is difficult to supply a large-scale through the spray pipe, etc., there is a disadvantage that the work to prevent the deposition and condensation of the powder is required. And since the secondary damage caused by the powder spread after spraying, despite the strong fire extinguishing power that can be applied to the ABCD class, its use is limited.

In the case of liquid extinguishing agents, spraying by pressure is possible, and the heat contained in the extinguishing agent is rapidly removed, and contact with oxygen occurs by forming a foam by the contained surfactant. On the other hand, it has a disadvantage in that the digestibility is weaker than the powders listed above, halon.

First, it shows more powerful fire extinguishing performance than general medicine used in class A fire, fire extinguishes rapidly due to high calorie absorbed during the firing process of sodium silicate, and nanoparticle size silicon produced after firing Contact with combustibles is blocked so no re-ignition occurs.

Second, when used in Class B fires, the foam produced by the surfactant prevents the diffusion of oil and blocks the contact with oxygen, and the extinguishing reaction can be achieved by the endothermic reaction occurring at the contact surface. It also applies to Class C fires.

Third, most of the composition of the extinguishing agent is harmless to the human body and the environment, so it is easy to store and handle, and has an excellent preservation.

Hereinafter, the above technical configuration will be described in more detail.

The general composition of the fire extinguishing agent that can be used for the ABC fire is a mixture of purified water, sodium silicate, surfactant, auxiliary fire extinguishing agent and cryoprotectant, but the liquid extinguishing agent composition according to the present invention is sodium silicate and surfactant as main fire extinguishing agent. It is characterized by allowing micelles formed to perform a powerful digestive action.

The liquid extinguishing agent composition according to the present invention forms a first solution by adding 5 to 200 parts by weight of surfactant and 0.0001 to 150 parts by weight of hydrochloric acid to 100 parts by weight of purified water,

10 to 150 parts by weight of a sodium silicate solution was added to the first solution to form a second solution,

The surfactant of the first solution is PEG: Polyethylene Glycol, MEG: Mono-Ethylene Glycol, PPG: Polypropylene Glycol, Fatty Acid Cocoyl Amide, Polyalkylene Glycol, Alkyl Dimethyl Amine Oxide, Alkyl Polyglucoside, Alkyl Dimethyl Betaine, Alkyl Propyl Betaine, Alkyl Amphoacetate, Lanolin, Lecithin, Saponin, Laury dimethylamine oxide, sodium laury sulfate, cetyltrimethyl ammonium chloride, lauramide, Pluronic P-123: Triblock copolymers poly (ethylene glycol) -poly (propylene glycol) -poly (ethylene glycol) (EO ₂₀ PO ₇₀ EO ₂₀ ), 1,12-diaminododecane, Pluronic F127-Triblock copolymer poly (ethylene oxide) -poly (propylene oxide) -poly (ethylene oxide) (EO ₁₀₆ PO ₇₀ EO ₁₀₆ ), Poloxamer 407, N-lauroylsacrosine, Pluronic 31R1: Triblock copolymer poly (propylene glycol) -poly (ethylene glycol) -poly (propylene glycol) (PPO ₂₇ -PEO ₄ -PPO ₂₇ ), Lauryl ether, Dodecylamine, Pluronic L-31 Triblock copolymer poly (ethylene oxide) -poly (propylene oxide) -poly (ethylene oxide) (PE _O1 -PPO ₁₆ -PEO1), Polyethylene glycol, Lauryl acid sodium salt, Hexadecylamine , Sodium dodecyl sulfate, Triton X-100: polyethylene glycol p- (1,1,3,3-tetramethylbutyl) -phenyl ether (C 14 H 22O (C 2 H 4O) n), Tween 20 or Polysorbate 20 -Polyoxyethylene (20) sorbitan monolaurate, Tween 40 or Polysorbate 40-polyoxyethylene (20) sorbitan monopalmitate, Tween 60 or Polysorbate 60- polyoxyethylene (20) sorbitan monostearate, Tween 80 or Polysorbate 80-Polyoxyethylene (20) sorbitan One or two or more of the monooleate, when the amount is less than 5 parts by weight does not form enough micelles, there is a problem that the performance of the extinguishing agent is deteriorated, and when the amount exceeds 200 parts by weight, the viscosity increases because the concentration is higher Since the spraying is not made smoothly and there is a problem that the extinguishing power of the extinguishing agent falls, it is desirable to keep the amount of the surfactant used within 5 to 200 parts by weight based on 100 parts by weight of purified water. It is.

If the amount of hydrochloric acid is less than 0.0001 parts by weight, the formation of micelles is low, the concentration of hydrogen ions in the digestive fluid is low, causing a problem of corrosiveness, and when exceeding 150 parts by weight of silicon particles are precipitated Since there is a problem in that the digestive liquid component is separated into a solid and a liquid, the amount of hydrochloric acid is preferably maintained within 0.0001 to 150 parts by weight based on 100 parts by weight of purified water.

The sodium silicate solution is water glass 1, water glass 2, water glass 3, water glass 4, 10 to 150 parts by weight of any one or two or more selected from a solution in which silicon or chaff ash is dissolved in sodium hydroxide It is prepared by adding 100 parts by weight of purified water and dissolving it at 10 to 100 ° C., when the amount of the sodium silicate solution is less than 10 parts by weight, there is a problem of insufficient extinguishing power due to less extinguishing agent, and exceeds 150 parts by weight. In this case, the extinguishing power is reduced by the amount of sodium silicate injected in excess of the amount of sodium silicate aligned on the outer wall of the micelle, and since the viscosity is high, there is a problem that uniform extinguishing fluid is not sprayed. Thus, the amount of the sodium silicate solution used is purified water 100 It is preferable to keep in the range of 10-150 weight part with respect to a weight part.

When the amount of the extinguishing agent used is less than 0.002 parts by weight, the extinguishing power is weak. When the amount of the extinguishing agent is exceeded 50 parts by weight, there is a problem that uniform injection of the extinguishing fluid is not made due to the high viscosity. The amount used is preferably 0.002 to 50 parts by weight based on 100 parts by weight of purified water.

In addition, when the amount of glycerin or methylene glycol is less than 0.1 parts by weight, there is a problem in which the digestive fluid freezes in winter, and when it exceeds 5.0 parts by weight, there is a problem in reducing the extinguishing power of the digestive fluid. It is preferable that the usage-amount maintains 0.1-5.0 weight part with respect to 100 weight part of purified water.

Hereinafter, the manufacturing process of the liquid extinguishing agent composition will be described.

Preparation of the liquid extinguishing agent composition according to the present invention,

Preparing a first solution in which a surfactant micelle is formed by adding and dissolving 5 to 200 parts by weight of a surfactant to 100 parts by weight of purified water at 10 to 90 ° C., and then adding 0.0001 to 150 parts by weight of hydrochloric acid;

Preparing a sodium silicate solution by adding 10 to 150 parts by weight of sodium silicate to 100 parts by weight of purified water and dissolving it at 10 to 100 ° C;

Preparing a second solution by adding the sodium silicate solution for 0.1 to 2 hours while stirring the first solution at a stirring speed of 50 to 500 rpm;

One or two or more extinguishing agents selected from sodium bicarbonate, potassium bicarbonate, ammonium bicarbonate, potassium carbonate, sodium carbonate, sodium triphosphate, ammonium phosphate, potassium sulfate, ammonium sulfate, glycerin, and methylene glycol in the second solution. After adding 50 parts by weight, any one or two selected from glycerin or methylene glycol is added through 0.1 to 5.0 parts by weight.

Looking at the details of each step as follows.

First Solution Preparation

After dissolving by adding 5 to 200 parts by weight of surfactant to 100 parts by weight of purified water of 10 ~ 90 ℃, it is a process of preparing a solution in which the surfactant micelle is formed by adding 0.0001 to 150 parts by weight of hydrochloric acid.

If the temperature of the purified water is less than 10 ° C takes a long time to form the micelles and there is a problem that does not sufficiently disperse, if it exceeds 90 ° C the formation of micelles is lowered, there is a problem that waste of energy occurs , The temperature of the purified water is preferably maintained at 10 ~ 90 ℃.

The hydrochloric acid is added for the micelle formation of the surfactant and the hydrothermal treatment of sodium silicate. At this time, neutralization of the basic sodium silicate component used in the subsequent step occurs by the hydrochloric acid added.

A feature of the present invention is to provide a liquid extinguishing agent composition having strong extinguishing power by dissolving or dispersing a surfactant in water to form a surfactant micelle, and dispersing sodium silicate on the outer wall of the micelle thus formed, thereby providing a first solution. The addition of hydrochloric acid in the manufacturing process and the amount thereof is one of the important techniques in the present invention.

Sodium Silicate Solution Preparation

As a separate process from the manufacturing process of the first solution, 10 to 150 parts by weight of sodium silicate is added to 100 parts by weight of purified water and dissolved at 10 to 100 ° C. to prepare a sodium silicate solution. At this time, if the amount of sodium silicate is less than 10 parts by weight, the digestibility of the digestive fluid is not sufficient, and if it exceeds 150 parts by weight, the extinguishing power is increased by the sodium silicate injected in excess of the amount of sodium silicate aligned with the outer wall of the micelle. Since the viscosity is high and there is a problem that uniform extinguishing liquid injection is not performed because the viscosity is high, the amount of the sodium silicate is preferably maintained in the range of 10 to 150 parts by weight based on 100 parts by weight of purified water.

In addition, when the sodium silicate dissolution temperature is less than 10 ° C, the dissolution rate of sodium silicate is low, and there is a problem that dissolution does not occur properly, and when it exceeds 100 ° C, it provides a sufficient dissolution rate for complete dissolution Since it is meaningless to exceed the said temperature, it is preferable to keep the said sodium silicate dissolution temperature in the range of 10-100 degreeC.

As the silicon source, chaff ash produced after burning rice husk in addition to silica sand may be used. In addition, water glass may be diluted and used. The water glass may be selected from water glass 1, water glass 2, water glass 3, and water glass 4, and may be used by adjusting the content and concentration of sodium silicate.

Second Solution Preparation

The second solution is prepared by adding the sodium silicate solution for 0.1 to 2 hours while stirring the first solution at a stirring speed of 50 to 500 rpm.

If the stirring speed maintained in the process of adding the sodium silicate solution is less than 50rpm, there is a problem in that the sufficient mixing of the solution is not made, if it exceeds 500rpm waste of power and the outer surface of the micelle formed by the surfactant Since there is a problem that the hydrothermal synthesis of sodium silicate is hindered, the stirring speed is preferably maintained in the range of 50 ~ 500rpm.

The time for adding the sodium silicate is to define the rate of addition of sodium silicate, and when the time for adding the sodium silicate is less than 0.1 hour, it is not possible to form a finely aligned particulate form of sodium silicate on the outer wall of the micelle formed by the surfactant. There is a problem, when the time exceeds 2 hours, the efficiency of the manufacturing process is lowered, and even better effect is not expected because it is meaningless, it is preferable to maintain the addition time of the sodium silicate for 0.1 to 2 hours.

The silicate formation of the surfactant and the soda silicate is aligned with the outer wall of the micelle thus formed through the second solution preparation step in the first solution manufacturing step, thus, the present invention, soda silicate on the outer wall of the micelle By aligning, a liquid extinguishing agent composition having a strong extinguishing function can be provided.

That is, the present invention adds hydrochloric acid for micelle formation of surfactant and hydrothermal treatment of sodium silicate, wherein the amount of hydrochloric acid is adjusted to the type and amount of surfactant and the amount of sodium silicate added.

Sodium silicate is aligned on the outer wall of the micelle to form a nano-size, so formed sodium silicate and surfactant particles are foamed by the surfactant when ejected to the flame, due to the thermal energy of the flame Firing occurs, and the solidification occurs in the form of foam as it is converted from a liquid to a solid. In addition, the particle size of each of the particles to generate a few micrometers of several ㎛, in this process absorbs the thermal energy of the flame and performs the function of blocking the contact with the oxygen of the flammable material leads to digestion.

Fire extinguishing agent and glycerin or methylene glycol addition

One or two or more extinguishing agents selected from sodium bicarbonate, potassium bicarbonate, ammonium bicarbonate, potassium carbonate, sodium carbonate, sodium triphosphate, ammonium phosphate, potassium sulfate, ammonium sulfate, glycerin, and methylene glycol in the second solution. After adding 50 parts by weight, any one or two selected from glycerin or methylene glycol is added to 0.1 to 5.0 parts by weight, and a fire extinguishing agent is added to the second solution to further enhance the extinguishing performance. It is also the process of adding glycerin or methylene glycol to prevent freezing.

The addition amount of the glycerin or methylene glycol is strongly generated freezing point due to the addition of the extinguishing agent can prevent freezing even if a small amount is added.

Extinguishing agent  Composition of the composition (Example 1, Example 2, Example 3 / unit: kg ) ingredient Example 1 Example 2 Example 3  Purified water 100 100 100  Sodium silicate 30 25 35 P123 {Triblock copolymers poly (ethylene glycol) -poly (propylene glycol) -poly (ethylene glycol), (EO ₂₀ PO ₇₀ EO ₂₀ )} 8 9 -  Sodium bicarbonate 0.5 3 2  Potassium bicarbonate - 2 One  Potassium sulfate - One -  Trisodium Phosphate - One 2  glycerin 0.1 0.5 0.5 F127 {Triblock copolymer poly (ethylene oxide)-poly (propylene oxide)-poly (ethylene oxide), (EO ₁₀₆ PO ₇₀ EO ₁₀₆ )} - - 8  Hydrochloric acid (36%) 12 10 10

Example 1 uses P123 {Triblock copolymers poly (ethylene glycol) -poly (propylene glycol) -poly (ethylene glycol), (EO ₂₀ PO ₇₀ EO ₂₀ )} as a surfactant and chaff as sodium silicate (sodium silicate) A solution in which ash is dissolved in sodium hydroxide is used. Looking at the specific manufacturing process as follows.

After adding 8 kg of P123 to 100 kg of purified water at 35 ° C., 12 kg of hydrochloric acid having a concentration of 36% was added and stirred at a speed of 30 rpm to dissolve P123 to prepare a first solution in which a surfactant micelle was formed.

Apart from the first solution, 15 kg of sodium hydroxide was added to 100 kg of purified water to dissolve, and 15 kg of chaff ash was added in a state of stirring at 100 rpm at 70 ° C. to completely dissolve to prepare a sodium silicate solution. Then, 8 kg of the prepared sodium silicate solution is added and mixed to the first solution to prepare a second solution. At this time, when the combustion temperature of the rice hull ash is high, the temperature is raised to 70 ° C. or more, and when the combustion temperature of the rice hull ash is low, the melting occurs at 60 ° C. This is because the crystallinity of the rice hull ash changes according to the combustion temperature, so it is dissolved at low temperature by maintaining amorphous when the combustion temperature is low, and the rate of melting is reduced because of the crystallization of the rice hull ash produced at high temperature. To dissolve. The sodium silicate solution is added while the first solution is stirred at 150 rpm.

Next, 0.5 kg of sodium bicarbonate is added to the second solution, and 0.1 kg of glycerin is added to complete the preparation of the extinguishing agent composition according to the present invention.

Here, when an excessive amount of sodium silicate solution is added to the first solution in which the surfactant micelle is formed, since the hydrothermal of silicon does not occur in the micelle produced by the surfactant, it is difficult to expect a digestive effect. It is important to add a small amount within the range.

In addition, in the case where a large amount of sediment is generated after completion of the mixing of the first solution and the sodium silicate solution, caustic soda may be added to remove the precipitate, and since a small amount of precipitated particles do not precipitate, there is no problem in the extinguishing effect. . Therefore, the amount and size of the particles precipitated in the solid phase is determined according to the addition amount of hydrochloric acid and sodium silicate, the composition of the exact ratio is required.

Example 2 uses P123 {Triblock copolymers poly (ethylene glycol) -poly (propylene glycol) -poly (ethylene glycol), (EO ₂₀ PO ₇₀ EO ₂₀ )} as a surfactant, and as sodium silicate (sodium silicate) Chaff ash is used water glass 1. Looking at the specific manufacturing process as follows.

After adding 9 kg of P123 to 100 kg of purified water at 35 ° C., 10 kg of hydrochloric acid having a concentration of 36% was added and stirred at a speed of 30 rpm to dissolve P123 to prepare a first solution in which a surfactant micelle was formed.

While stirring the first solution at 150 rpm, 68 kg of water glass No. 1 was slowly added and mixed at a rate of 2.0 kg / min to prepare a second solution.

Next, 3.0 kg of sodium bicarbonate, 2.0 kg of potassium bicarbonate, 1.0 kg of potassium sulfate, 1 kg of sodium triphosphate are added to the second solution, and 0.5 kg of glycerin is added to complete the preparation of the extinguishing agent composition according to the present invention.

Here, since the water glass has a high density and a high viscosity, hydrothermal synthesis of silicon occurs only when dispersion and mixing are performed smoothly, so that the water glass should be added slowly while maintaining agitation in the complete mixing state of the first solution and the water glass.

Example 3 uses F127 {Triblock copolymer poly (ethylene oxide) -poly (propylene oxide) -poly (ethylene oxide), (EO ₁₀₆ PO ₇₀ EO ₁₀₆ )} as a surfactant and chaff as sodium silicate (sodium silicate) We use water glass 1 for ashes. Looking at the specific manufacturing process as follows.

After adding 8 kg of P127 to 100 kg of purified water at 35 ° C., 10 kg of hydrochloric acid having a concentration of 36% was added and stirred at a speed of 30 rpm to dissolve P127 to prepare a first solution in which a surfactant micelle was formed.

While stirring the first solution at 150 rpm, 90 kg of water glass No. 1 was slowly added and mixed at a rate of 2.0 kg / min to prepare a second solution.

Next, 2.0 kg of sodium bicarbonate, 1.0 kg of potassium bicarbonate, 2 kg of sodium triphosphate are added to the second solution, and 0.5 kg of glycerin is added to complete the preparation of the extinguishing agent composition according to the present invention.
