Description

Fire extinguishing agent for topical suppression {Fire extinguishing}

The present invention relates to a fire extinguishing agent for topical suppression, in which fire extinguishing is completely performed regardless of a fire generating object, as well as minimizing soil contamination, harmless to human body, and having excellent storage and storage stability.

Currently, water or powder extinguishing agents are commonly used in fires, but water extinguishing agents have a relatively high freezing point of 0 ° C, making it difficult to use outdoors in the cold or winter months. If the car damage is very large and if it is not shaken more than once every six months during care and handling, it will easily harden and radiate when needed. It is difficult to store especially when the humidity is high.

Forest fires, which are Class A fires, use foam fire extinguishing agents, but they do not have a great effect in terms of performance and there is no suitable fire extinguishing agent in developed countries.

In general, reinforcing liquid extinguishing agents are widely used because they have the highest extinguishing power for oil fires, which are Class B oils. However, fire retardants for A class fires, especially forest fires, have poor extinguishing power. It is true.

Meanwhile, in developed countries such as the United States and Japan, drugs for Class B fires are already harmless to the human body and have developed and marketed neutral reinforcement liquids with excellent corrosion properties for various materials. However, there is no reinforcing liquid extinguishing agent with excellent extinguishing performance in Class A fires. In Korea, since the basicity of the liquid extinguishing agent is recognized in accordance with the type approval and certification technique of the extinguishing agent of Korea Fire Protection Agency, the strengthening liquid extinguishing agent developed and marketed in Korea is strongly basic and It is being developed for cooking oil fires.

Although the liquidity of the reinforcing liquid extinguishing agent does not affect the extinguishing power, the secondary damage occurs due to human damage during fire extinguishing or corrosion of certain parts of the existing automatic fire extinguishing equipment, and even if the extinguishing power is excellent, only legally recognized neutrality is recognized. There was a problem that could not enter the world market.

In light of the global trend, the demand for reinforcing liquid extinguishing agents will increase greatly, but there is a serious problem that the reinforcing liquid extinguishing agent must be fully dependent on imports when the regulation is strengthened for the purpose of corrosion and stability to the human body.

Looking at the conventional literature on general fire extinguishing agents, for example, U. S. Patent No. 5,909, 776 describes dispersed particulates of dry powder extinguishing agents having an average particle size of up to 500 microns, powdered perfluorocarbons, hydrochlorofluorocarbons and hydrofluoro A fire extinguisher comprising a gas selected from the group consisting of carbon and a fire extinguishing composition comprising a gel having a surfactant and a stabilizer is disclosed, US Pat. A fire extinguishing method using a extinguishing agent having a surfactant and water is described.

In addition, Korean Patent Publication No. 93-3391 discloses C1-C5 halogenated alkanes such as bromochlorodifluoromethane, bromotrifluoromethane, dibromodifluoromethane or mixtures thereof, and trialkylphosphates and triaryls. Extinguishing agent compositions made of organophosphorus compounds such as phosphate and trihalogenated alkyl phosphates are described. Korean Registered Publication No. 97-9308 discloses Sapinacea, Composita, Crucifera, Leguminosa and Ulmasea. A digestive composition comprising an aqueous extract of a plant such as Eh et al. And a surfactant such as dodecyl polyetheneoxy sodium sulfate and sodium dodecyl aminopropionate has been described.

In addition, Korean Patent No. 10-117936 discloses a method for preparing a liquid extinguishing agent obtained by dissolving ammonium sulfate in water, adding urea to dissolve, and then adding sodium triphosphate, followed by dissolving ammonium bicarbonate and sodium carbonate in turn. Korean Patent No. 10-259512 discloses a method for preparing a liquid fire extinguishing agent obtained by dissolving soda ash in water, dissolving by adding sodium triphosphate, and then dissolving by adding ammonium sulfate and urea in turn. Patent No. 10-112862 describes preparing a first aqueous solution of ammonium bicarbonate and sodium phosphate in water, preparing a second aqueous solution of urea, ammonium sulfate, and sodium carbonate in water, and dissolving calcium chloride in alumina sulfate. A method for preparing a liquid extinguishing agent prepared by preparing a third solution and mixing the three solutions is described.

However, such a conventional conventional fire extinguishing agent has a low fire extinguishing performance and extremely inferior flame retardant effect in case of a Class A fire including a forest fire. In addition, the conventional domestic fire extinguishing agent has a problem that harmful to the human body during the radiation and because the liquidity is basic, and also affects the soil, causing a secondary problem is large corrosive.

The present invention has been invented to solve the above problems, the purpose of which is to completely extinguish irrespective of the subject of fire, as well as to minimize soil contamination, harmless to the human body, excellent storage and storage stability It is to provide a fire extinguishing agent for topical suppression.

Characteristic technical configuration of the present invention for achieving the above object is to form a fire extinguishing agent for use in dilution in a ratio of water 100: 1-water 500: 1, the topical extinguishing agent is a fat, alkaline, 15 to 54.9% by weight, 10 to 20% by weight surfactant, 2 to 15% by weight stabilizer, 0.1 to 2% by weight pH adjuster, water 30 to 48 Weight percent.

And the pH adjuster is any one of acetic acid, formic acid, lactic acid, citric acid, malic acid, glucono delta lactone, boric acid, the fat or oil used to prepare the soap is any one of animal or vegetable oil, the surfactant is an anion One or two of a surfactant, a nonionic surfactant, and an amphoteric surfactant are mixed, and the soap is a powder of a solid soap prepared by mixing a fat, an alkaline agent, and water at a predetermined ratio, or a liquid One of the soaps, the stabilizer is sodium carbonate, sodium bicarbonate, sodium sulfate, sodium phosphate, urea, sodium borate, ethanol, methanol, isopropyl alcohol or a mixture of two or more.

The fire extinguishing agent for topical suppression of the present invention as described above is completely digested even in the case of chemicals having good flammability, as well as transplanting the flowers to the ground of the experimental paper and periodically giving water to grow the plants without dying. In addition, the side effects of the fire extinguishing agent does not cause side effects.

The fire extinguishing agent for topical suppression of the present invention forms a fire extinguishing agent for use by diluting water 100: 1-water 500: 1 in a ratio of about 1. 15 to 54.9% by weight of soap, 10 to 20% by weight of surfactant, 2 to 15% by weight of stabilizer, 0.1 to 2% by weight of pH adjuster, and 30 to 48% by weight of water.

In the present invention, the use of a soap prepared by mixing a fat, alkaline agent, and water in a predetermined ratio and preparing the same in a conventional manner is because foaming exerts a special effect on topical suppression, which has been proved through many experiments. Since it is true, detailed description thereof will be omitted.

The reason for using waste vegetable oil among the components for preparing the soap is to recycle the waste vegetable oil, which is an environmental pollutant, to prevent environmental pollution, and to reduce the manufacturing cost of the soap to have economical efficiency.

The soap prepared by the conventional method may mean that of the registered patent No. 10-804818 registered in advance, in addition to the liquid soap prepared by mixing fat, alkali, water in a certain ratio Alternatively, the solid phase refers to all soaps, and the liquid soap may be used as it is, but it is preferable to use the solid soap as a powder.

As described above, the fire extinguishing agent for topical suppression is essentially a foaming soap 15-54.90 wt%, a surfactant 10-20 wt%, a stabilizer 2-15 wt%, and a pH adjuster 0.1-2 30% by weight to 48% by weight of water is used.

The pH adjuster using any one of acetic acid, formic acid, lactic acid, citric acid, malic acid, glucono delta lactone, boric acid, the amount used is 0.1-2% by weight, because the fire extinguishing agent for topical suppression of the present invention is soil pollution Prevention is, of course, used to maintain the stability of the product, using less than 0.1% by weight or more than 2% by weight is difficult to maintain the product quality required by the present invention. Therefore, the pH adjuster is preferably used 0.1 to 2% by weight.

In addition, the reason why the stabilizer is used in the fire extinguishing agent of the present invention is that the long-term storage of the fire extinguishing agent of the present invention causes coagulation or segregation due to the difference in physical properties of each component. This is to prevent this.

The stabilizer may be any one or two or more of sodium carbonate, sodium bicarbonate, sodium sulfate, sodium phosphate, urea, sodium borate, ethanol, methanol, isopropyl alcohol.

On the other hand, 2 to 15% by weight of the stabilizer is used because it is necessary to adjust the amount of use of each component to form a fire extinguishing agent for topical suppression according to the present invention.

In addition, the reason why 30 to 48% by weight of water is used in the fire fighting extinguishing agent of the present invention is that water serves as a medium for dissolving the above components, and at the same time, functions to retain these components and maintain the extinguishing agent. Water can also be used as tap water or purified water.

Surfactant of the present invention is used to reduce the surface tension of the extinguishing agent composition to 33dyne / cm or less 10 to 20% by weight, the surface tension is a value that is commonly required in the industry.

In addition, it is preferable to use any one of sodium alkylbenzene sulfonate and higher alcohol sulfate ester salt as an anionic surfactant, but a conventional water-soluble surfactant can be used if necessary, and more specifically, lauryl Dimethylamine oxide (lauryl dimethylamine oxide), sodium lauric sulfate (sodiumlaury sulfate), cetyltrimethyl ammonium chloride (cetyltrimethyl ammonium chloride), lauamide DEA (lauramide DEA) and the like can be used.

In addition to the anionic surfactant, the surfactant may be a mixture of any one or two of nonionic surfactants and amphoteric surfactants.

In addition, the fire extinguishing agent for the topical suppression of the present invention may be used alone or in combination of ethylene glycol, diethylene glycol, propylene glycol in order to prevent freezing even below minus 20 ℃.

Fire extinguishing agent for topical suppression according to the present invention as described above is stored in a closed container and used when diluted with the ratio of water 100: extinguishing agent 1-water 500: extinguishing agent 1.
