Description

FIELD OF THE INVENTION The present invention relates to a fire extinguishing agent using liquid soap and making method,

The present invention relates to an environmentally friendly fire extinguishing agent and a method for producing the same. More particularly, the present invention relates to a fire extinguishing agent which is eco-friendly and excellent in digestion ability by using a water brewer made of discarded waste oil as a main raw material, and a method for producing the same.

Currently, water or powder fire extinguishing agent compositions are commonly used in general fire.

However, in the case of the water-extinguishing agent composition, the freezing point is relatively high at 0 ° C, and it is difficult to use the composition outdoors due to freezing due to low temperature below 0 ° C in cold or winter. In the case of powdered fire extinguishing composition, Is very large, and if it is not shaken more than once every six months when it is handled and handled, it hardens easily, causing a problem that it is not radiated when the fire is extinguished.

A foam fire extinguishing composition is used in general fire, A class fire, but it has no effect on its performance and it is required to develop a new fire extinguishing composition because there is no suitable fire extinguishing composition in advanced countries.

Generally, the fire extinguishing agent composition has the best fire extinguishing power for oil fire, which is class B, and is widely used. However, it is in urgent need to develop a fire extinguishing agent composition having excellent fire extinguishing performance because it shows poor fire extinguishing power especially in forest fire.

Meanwhile, PFOS, which is contained in fire-extinguishing agent compositions, is composed of fluorine-based compounds consisting of carbon and fluorine. In 2009, according to the Stockholm Convention (international regulations on persistent organic pollutants) Material.

In Korea, the use of organic pollutants has been restricted by the Residual Organic Pollutants Control Act from April 2011. However, since the substitute materials have not been found yet, they are in use and development is urgent.

It is known that the toxicity of PFOS affects the ecosystem, that is, it induces reproductive toxicity of aquatic animals, and furthermore, it has harmful effects such as cancer, hormonal system and immune system disturbance and malformed birth. In addition, hydrolysis, photodegradation and biodegradation do not occur in sustainability. Therefore, decomposition is possible only when incinerated at high temperature (1,100 ° C). The exposed harmful substances accumulate at high concentrations in association with blood and liver proteins.

In recent years, advanced countries such as the US and Japan have developed and marketed a chemical-based reinforcing agent that is harmless to the human body and low in corrosion characteristics for various materials, and is commercially available. However, there is no strengthening liquid fire extinguishing agent with excellent fire extinguishing performance in Class A fire.

In the case of domestic fire extinguishing agent approval and certification standards of the Korea Fire Protection Authority, strengthened liquid fire extinguishing agent is basically approved for the liquidity, so it is strongly basic in the case of fire extinguishing agent composition developed and marketed in Korea, It is being developed as a medicine to enter the fire extinguisher.

The liquidity of the fortified liquid fire extinguishing composition does not affect the digestive power, but it may cause secondary damage due to personal injury during digestion and corrosion of certain parts of existing automatic fire extinguishing facilities.

Korean Patent Publication No. 10-2012-0054245 discloses a fire extinguishing agent for fire suppression.

The extinguishing agent is diluted with water at a ratio of 100: 1 - water: water: 500: 1 to form an extinguishing agent for use in the extinguishing agent. The extinguishing agent for the extinguishing agent is prepared by mixing the preservative, the alkaline agent, 15 to 54.9% by weight of soap, 10 to 20% by weight of a surfactant, 2 to 15% by weight of a stabilizer, 0.1 to 2% by weight of a pH adjusting agent and 30 to 48% by weight of water.

Although the fire extinguishing agent contains soap as a main component, its content is low and the fire extinguishing ability is not high.

The method of manufacturing an environmentally friendly fire extinguishing agent according to the present invention comprises the steps of preparing a water-containing bath from a waste oil, preparing a water-containing bath, mixing the water, water, . Each step will be examined in detail.

1. Wetting Step

a) Manufacture of solid soap

First, the lungs are made into solid soaps through a saponification reaction.

Waste cooking oils can be used for lung maintenance. It is desirable to use the waste cooking oil because it is mixed with various foreign substances and filtered.

To produce filtered soap as solid soap, a caustic soda solution is added to the waste oil to saponify. The caustic soda solution may be prepared by dissolving 50 to 80 parts by weight of caustic soda in 100 parts by weight of water.

5 to 30 parts by weight of a caustic soda solution is mixed with 100 parts by weight of the waste oil, and the saponification reaction proceeds at 40 to 50 ° C. Upon completion of the saponification reaction, the solid soap is obtained by cooling. The cooling can be carried out by leaving at room temperature for 2 to 6 hours.

b) Acquisition of powdered soap

The pulverization step is carried out to make the obtained solid soap into powder soap. Through the grinding step, the solid soap in the form of lumps is made of powdered soap. The average particle size of the powdered soap is about 20 to 100 mesh.

c) Acquisition of base solution

Next, potassium hydroxide is mixed with fatty acid to obtain a base solution.

As the fatty acid, lauric acid may be used. Lauric acid has excellent foaming power. 10 to 30 parts by weight of potassium hydroxide is added to 100 parts by weight of the fatty acid, and the mixture is stirred to prepare a base solution.

d) stirring

Next, powdered soap and organic acid are added to the base solution and stirred.

5 to 15 parts by weight of powdered soap and 0.1 to 1.0 part by weight of organic acid may be added based on 100 parts by weight of the base solution. The organic acid may be citric acid as a pH control agent for the water buffy.

The base solution to which the flour soap has been added is stirred at 35 to 45 캜 for 30 to 90 minutes to obtain a water bath.

On the other hand, in the stirring step, the natural extract can be further added to the base solution. For example, 5 to 15 parts by weight of a powdery soap, 0.1 to 1.0 part by weight of an organic acid, and 1 to 10 parts by weight of a natural extract may be added to 100 parts by weight of the base solution, followed by stirring.

An example of a natural extract is bamboo shoots.

The bamboo flour is intended to increase the antimicrobial activity and to remove the unpleasant odor of waste cooking oil. The bamboo flour is obtained by condensing the smoke generated when bamboo is made into charcoal, and is excellent in antibacterial and deodorizing effect.

Another example of a natural extract is an extract of Aspergillus oryzae. The antioxidant activity of Ganoderma lucidum extract is effective to inhibit the rancidity of the water so that the preservation can be improved by preventing the deterioration of the water.

Wedelia prostrata is a perennial herb that grows on the beach.

A variety of extraction methods can be applied to obtain the extract of Bacillus subtilis. One of the extraction methods can be obtained by adding an extraction solvent. As the extraction solvent, at least one selected from water, a lower alcohol having 1 to 4 carbon atoms, a polyhydric alcohol, or a mixture thereof may be used. As the lower alcohol having 1 to 4 carbon atoms, methanol, ethanol and the like can be used. As the polyhydric alcohol, butylene glycol, propylene glycol, pentylene glycol and the like can be used. Mixtures of water and lower alcohols, mixtures of water and polyhydric alcohols, mixtures of lower alcohols and polyhydric alcohols, or mixtures of water and lower alcohols and polyhydric alcohols can be used as the mixture.

As an example of the extraction, an extraction solvent may be added in an amount of 2 to 20 times by weight of the extraction solvent, and then subjected to hot water extraction, cold extraction or warm-up extraction at 10 to 150 ° C for 1 to 48 hours. After extraction, the extract is filtered to obtain a liquid extract of Aspergillus oryzae.

EXAMPLES Hereinafter, the present invention will be described in more detail with reference to the following examples. However, the scope of the present invention is not limited to the following examples.

(Example)

After the foreign materials were removed by drying the waste cooking oil, 20 parts by weight of the caustic soda solution was mixed with 100 parts by weight of the waste oil, followed by saponification at 45 캜 and cooling to produce a solid soap. And 60 parts by weight of caustic soda was dissolved in 100 parts by weight of water as a caustic soda solution.

The obtained solid soap was pulverized to make powdered soap having a size of about 80 mesh.

20 parts by weight of potassium hydroxide was added to 100 parts by weight of lauric acid and stirred to prepare a base solution. 10 parts by weight of powdered soap and 0.2 part by weight of citric acid were added to 100 parts by weight of the prepared base solution, and the mixture was stirred at 40 DEG C for 60 minutes to prepare a water bath.

Subsequently, 6.2 parts by weight of propylene glycol, 3.7 parts by weight of sodium alkylbenzenesulfonate, 6.2 parts by weight of sodium lauryl sulfate, 5 parts by weight of glycerin and 0.62 part by weight of citric acid were mixed with 100 parts by weight of waterwash to prepare an extinguishing agent Respectively.
