In general, when a fire or an explosion occurs inside a building or subway, toxic gas is generated. Due to the toxic gas generated, the evacuator often suffocates before reaching the exit. In case of an emergency such as a collapse of a gang in a mine such as a coal mine or a mine, death is often caused by lack of oxygen just before being rescued. To protect valuable lives from these accidents, gas masks or oxygen masks are used.

However, in the case of gas mask, there is an advantage that it can protect human life somewhat effectively when toxic substances are generated, but it is easy to be useless in an emergency situation such as lack of surrounding oxygen. Accordingly, in recent years, researches on oxygen generating masks that can be usefully used even when external air is toxic and useful even in a state where oxygen is insufficient in the outside air have been actively conducted. A mask is disclosed.

However, the mask using compressed oxygen stored in the oxygen tank has a lot of problems in wearability and portability because the oxygen tank is bulky and heavy, and in particular, since the capacity of the air supplied from the oxygen tank is limited, the evacuation to a safe place is very short. If the time is long, there is a problem that can not be useful.

In order to solve this problem, a number of techniques related to an oxygen generating mask using an oxygen generating agent containing a compound that generates oxygen by reacting with moisture or carbon dioxide generated in the wearer's breathing process instead of using compressed oxygen have been disclosed. . As the oxygen generating compound embedded in the oxygen generating agent, excess potassium oxide (KO ₂ ) or sodium peroxide (Na ₂ O ₂ ) is mainly used. The mechanism by which the excess potassium oxide and sodium peroxide react with carbon dioxide or water to generate oxygen is shown in Schemes 1 and 2.

Formula 1

Formula 2

Regarding the technology of using sodium peroxide and potassium peroxide, Korean Utility Model Registration No. 383904 discloses a technique of using these compounds in a nonwoven fabric. However, as shown in Schemes 1 and 2, excess potassium oxide (KO ₂ ) or sodium peroxide (Na ₂ O ₂ ) reacts with carbon dioxide or water to generate oxygen, which is known as manganese oxide. If there is no reaction, there is a problem that less oxygen generation.

In addition, KOH and NaOH, the adducts generated in Scheme 1, are dissolved in water at room temperature and changed into a liquid. These liquids leak from the nonwoven fabric, which causes a problem of wearing safety when breathing. In addition, KCO ₃ and Na ₂ CO ₃ generated in the reaction formula 2 has a problem of reducing the oxygen generation efficiency by preventing the generation of oxygen by absorbing moisture to form a film on the surface.

Referring to US Pat. No. 5165399, a carbon dioxide absorbent in which lithium hydroxide (LiOH) is mixed with PTFE and processed into a sheet is disclosed, and when processed, it can be used as an air purifier filter. However, this technique has a disadvantage of using a separate nonwoven fabric or fabric in order to maintain the structural stability of the carbon dioxide absorbent, and the biggest disadvantage is that it is difficult to process in the form of a thin film or a small diameter fiber or filament.

Korean Patent Laid-Open Publication No. 2006-0053043 (2006.5.19) relates to a composition used for the purpose of purifying air, and more particularly, peroxide or superoxide and silicon, that is, polyor The invention relates to a polymer air purifier composition composed of a polyorganosiloxane and a filter using the same, and an oxygen generation amount is inadequate for use as a self-contained oxygen generator in an emergency situation.

As another example, U.S. Patent No. 5964221 discloses a melt extruded sheet mixed with an alkaline air purifier such as lithium hydroxide and calcium hydroxide and mixed with high molecular weight polyethylene (UHMWPE, ultra-high molecular weight polyethylene) and mineral oil. It is disclosed that the sheet according to the technique has a single structure, and does not require the use of a separate nonwoven or woven fabric to maintain the structure, such as US Pat. No. 5,516,399.

However, this technique uses mineral oil as a lubricant during extrusion, which has to be removed later through a washing process using an organic solvent. In particular, the mineral oil used as a lubricant or an organic solvent used for washing is easily ignited. This technique cannot be applied to highly oxidizing air cleaners such as potassium oxide or sodium peroxide.

Potassium acetate or sodium peroxide has been used as an air revitalization material or air purifier, which reacts with the following chemical formulas (1) and (2) to fix the carbon dioxide contained in the air and Because it causes

In addition, potassium peroxide (K ₂ O ₂ ), calcium peroxide (calcium peroxide, CaO ₂ ), lithium peroxide (lithium peroxide, Li ₂ O ₂ ), sodium superoxide (NaO ₂ ) and superoxide Potassium superoxide (KO ₂ ) may be used as an air purifier because it absorbs carbon dioxide contained in the air and generates oxygen.

The peroxides and superoxides are mainly manufactured in pellet form and then filled in a constant container such as a column to form an air purification system, whereby the mechanical properties of the pellets are improved or the fusion between the pellets is prevented. A small amount of binder is usually added for the purpose of doing so.

For example, WO 03/009899 A1 discloses an air purifier in which up to 3.0 wt% of a binder is mixed with superoxides or peroxides of alkali or alkaline earth metals, wherein sodium silicate is used as an inorganic binder. silicate, Na ₂ SiO ₃ ) and potassium silicate (K ₂ SiO ₃ ) were used as organic binders such as sodium polyvinyl tetrazole, sodium carboxyl cellulose, polyvinyl acetate, nitrocellulose, epoxy resin, and the like. It is revealed.

U.S. Patent No. 4,113,646 discloses anhydrous calcium sulfate (CaSO ₄ ), silicon dioxide (SiO ₂ ), lithium monoxide (Li ₂ O), lithium metaborate (LiBO ₂ ), and the like. It is disclosed that not only can solve the problem of fusion of potassium acetate by addition, but also improve the oxygen generation performance.

The present invention is to solve the above problems, potassium oxide (KO ₂ ) for oxygen generation to increase the oxygen generation time by preventing the rapid reaction of carbon dioxide or water generated during respiration to generate high heat The purpose is to provide a cartridge.

The present invention compresses and processes the powder mixed with potassium acetate and manganese oxide or manganese dioxide (MnO ₂ ) and converts carbon dioxide into oxygen and supplies it again, but an oxygen generating cartridge including an oxygen generator therein.

Here, the oxygen generator is characterized in that it is composed of potassium acetate and manganese oxide.
In addition, when only 100% of potassium acetate is used alone as an oxygen generator, it is difficult to take out a chemical reaction close to 100% regardless of the shape. Here, by using a manganese oxide known to generate oxygen as an inorganic catalyst as a catalyst, the chemical reaction of KO ₂ can be facilitated, and the chemical reaction can be improved to about 90%.

In addition, the chemical formula in which human carbon dioxide (CO ₂ ) and water (H ₂ O) react with KO ₂ is shown below.

Formula 3

Formula 4

KO ₂  + H ₂ O ---> 2KOH +2/3 O ₂

The present invention is characterized in that potassium acetate is 99 to 90 parts by weight and manganese oxide is 1 to 10 parts by weight.

The theoretical value of the pure oxygen generation amount that KO ₂ can generate by the chemical reactions 3 and 4 is 234 cc / g. When 60 g of KO ₂ causes 100% chemical reaction, it is 234 × 60g = 14,040 cc (about 14L), but the oxygen concentration in general air is about 20%, so it can absorb 14L × 5 = 70L of air. do. However, in the reaction of KO ₂ alone, it is difficult to cause 100% of reactions with only the human-emitted moisture and carbon dioxide, which is less than 50% of theory. In other words, the air supply capacity is less than 35L. For this reason, the product maintains the oxygen supply by using more than twice the theoretical value of KO ₂ . In the present invention, by improving the chemical reaction level to more than 90% by using a small amount of KO ₂ than the conventional KO ₂ oxygen generator alone, the oxygen generation was made practical by realizing the weight and compactness of the product.

The manganese oxide is preferably used in the range of 1 part by weight to 10 parts by weight with respect to 99 to 90 parts by weight of superoxide, because the use of less than the above lower limit has the disadvantage of reducing the amount of oxygen generated, more than the above upper limit. When used, it is difficult to lower the oxidation power of superoxide.

When only 100% of potassium acetate is used alone as an oxygen generator, it is difficult to bring out a chemical reaction close to 100% regardless of the shape. Here, by using a manganese oxide known to generate oxygen as an inorganic catalyst as a catalyst, the chemical reaction of KO ₂ can be facilitated, and the chemical reaction can be improved to about 90%.

In addition, the chemical formula by which human carbon dioxide (CO ₂ ) and water (H ₂ O) react with KO ₂ is shown below.

The present invention is characterized in that potassium acetate is 99 to 90 parts by weight and manganese dioxide is 1 to 10 parts by weight.

Theoretical value of pure oxygen evolution that potassium acetate can be generated by the chemical reactions 3 and 4 is 234 cc / g. When 60 g of KO ₂ causes 100% chemical reaction, it is 234 × 60g = 14,040 cc (about 14L), but the oxygen concentration in general air is about 20%, so it can absorb 14L × 5 = 70L of air. do. However, in the reaction of KO ₂ alone, it is difficult to cause 100% of reactions with only the human-emitted moisture and carbon dioxide, which is less than 50% of theory. In other words, the air supply capacity is less than 35L. For this reason, the product maintains the oxygen supply by using more than twice the theoretical value of KO ₂ . In the present invention, by improving the chemical reaction level to more than 90% by using a small amount of KO ₂ than the existing KO ₂ oxygen generator alone, the oxygen generation was made practical by realizing the weight reduction and compactness of the product.
