The present invention relates to a composition having a sterilizing and disinfecting effect by heat and steam steam and a sterilizing agent using a composition including a thermochemical reaction composition and a sterilizing agent at the same time.

There are a myriad of bacteria in our environment. For example, many of the microorganisms are contained in the food we eat and drink, in the soil or in the air.

Due to this environment, our hands are also contaminated with many kinds of microorganisms. It is generally known that a large number of microbial species, such as Escherichia coli and Staphylococcus aureus, are detected in the human hand. Among these, there may be pathogenic bacteria that cause oral infection in humans and cause food poisoning, and there may be bacteria that have no effect.

Microorganisms, like all living organisms, have suitable and inadequate environments for life, and their growth and physiological properties depend on the given environment. The suitable environment is originally determined according to the type of microorganisms, and by revealing it, it can be used artificially to make it suitable for a specific microorganism, and it can be usefully used for its growth. Can be achieved effectively.

Factors affecting the growth of microorganisms include physical factors such as temperature, light, and pressure, chemical factors such as moisture, pH, oxygen, salt, and chemicals, and biological factors such as symbiosis and antagonism.

To artificially remove microorganisms, it is common to use temperature sterilization or chemical sterilization.

Looking at the conventional technology that can be utilized for temperature or chemical sterilization, Korean Patent No. 10-0442560 provides a heating element that generates heat by reacting with water or an aqueous solution consisting of CaO, metal chloride, NaOH, Al powder, but its use is It is for heating the food or beverage instantaneously, and since the composition does not contain a disinfectant and can provide only heat and a small amount of steam below 100 ° C., it is not sufficient to obtain a sterilizing effect.

Korean Patent Laid-Open No. 2001-0105069 provides a heating element in the form of micronized and pressed solidified CaO, and Korean Patent No. 10-0422317 is prepared by mixing a magnesium-based alloy, an electrolyte, an acid, a basic material, and a catalyst material. It provides a heating element, but like heating 10-0442560, it is for heating food and does not contain a disinfectant.

Republic of Korea Patent No. 10-0681389 is a heating element that generates heat by reacting with water to provide a sintered body consisting of CaO, metal chloride, Al or Mg powder, but is intended to heat food as in Patent 10-0442560 and Patent 2001-0105069, Due to the characteristics of the sintered body, since the reaction with water occurs gradually, the sterilization effect by providing steam and heat is more insignificant.

Japanese Patent No. Hei 6-227158 provides a sterilization method using a heating and sterilizing agent, but for sterilization of contaminated water or inside a pipe, a hydrogen peroxide solution heated to less than 60 ° C. using an external heating body is used. It is limited, it is difficult to expect the sterilization effect by heat and steam, and since only using hydrogen peroxide as a sterilizing agent has a disadvantage of low sterilization power, stability and convenience of use.

Conventional technology using a heating agent that reacts with a disinfectant and water includes a sterilization deodorant container containing a sterilizing deodorant, a heating agent container containing a heating agent, and a sterilizing deodorant fumigation device consisting of a reaction container, but using only CaO as a heating agent and using water and In addition, by causing an exothermic reaction in the reaction vessel to heat the sterilization deodorizing vessel to induce the vaporization of the sterilization deodorant (Korean Registered Room 20-0225314, Republic of Korea Registered Room 20-0254152 and Republic of Korea Patent Publication 1986-0003773). Therefore, the heating agent used in the fumigation apparatus is used as the heating of the container to vaporize the sterilizing deodorant. In addition, it is difficult to expect the sterilization effect by heat or steam, and the object of sterilization is also limited only to the gas and the container or tube in contact with the gas.

The prior art includes a technique such as heating of the sterilizer by the external heat mechanically and physically separated from the sterilizer and vaporization of the sterilizer, but the contaminated aqueous solution using heat (temperature), steam (water vapor) and the sterilizing agent at the same time. There is no technique for effectively sterilizing the inner wall, outer wall, wall surface, etc. of an unspecified shape of the container.

The present invention for solving the problems of the prior art has a range of sterilization target, such as the inner wall or outer wall, wall surface of the waste water solution, unspecified container while improving the sterilization power by simultaneously providing heat and chemicals to obtain a sterilization effect It is an object of the present invention to provide a sterilization steam pack using the sterilization composition of the present invention and not limited.

The sterilant composition of the present invention for achieving the above object is a mixture of sterilant powder for sterilizing exothermic material and organic material which generate heat by reacting with water to increase heat and steam (water vapor) and activity of the sterilant. It is.

Preferred bactericidal composition of the present invention is characterized by including 100 to 6000 parts by weight of calcium oxide, magnesium oxide or mixed powder thereof and 100 to 5000 parts by weight of basic anhydride with respect to 100 parts by weight of the fungicide powder.

At this time, calcium oxide, magnesium oxide or mixed powder thereof is a heat generating agent, and reacts with water (aqueous solution) to become a hydroxide while generating heat to increase the temperature of water (aqueous solution) and provide steam (water vapor).

The temperature of the wastewater raised by the heat generating agent increases the activity of the sterilizing agent to induce a more effective sterilizing action, and can be sterilized by heat itself by maintaining a high temperature to provide steam for a long time. In addition, it is possible to sterilize the periphery of the container containing the waste water by using the high temperature steam (vapor) made by the heat generating agent.

The sterilant powder sterilizes the wastewater, the wall surface of the container in contact with the wastewater, but can also be sterilized around the container by the sterilizer vaporized by the high temperature.

As described above, since the sterilization composition of the present invention is sterilized by heat and steam as well as chemical sterilization, sterilization of the wastewater solution (contaminated aqueous solution) as well as bacteria on the inner wall of the wastewater solution can be sterilized by steam.

Therefore, unlike conventional sterilizers using a liquid or solid disinfectant to disinfect only the wastewater solution, or using a liquid or gas disinfectant to sterilize the inner wall of the container or contaminated air, the wastewater solution using the disinfectant composition of the present invention. In addition, the air of the inner wall, outer wall, wall surface or enclosed space of an unspecified container can also be sterilized.

The disinfectant may be used as long as it is dissolved in water and an anhydrous disinfectant in a solid state, but is preferably sodium isocyanate chloride, potassium isocyanate chloride, sodium bromide isocyanate, potassium bromide isocyanate or potassium hypochlorite. , Calcium hypochlorite, potassium hypochlorite, triclozan, quaternary ammonium salts, iodine compounds or adipic acid, or mixtures thereof, preferably anhydrides.

Most preferably, it is most preferable to use a fungicide in which sodium isocyanate dichloride: adipic acid is mixed in a weight ratio of 3: 1 to 1: 1.

The disinfectant mixed with sodium isocyanate dichloride and adipic acid of the present invention is the most advanced formulation of chlorine disinfectant disinfectants to maximize sterilization and stability, and active sterilization components are maintained even in the presence of organic matter. It completely kills pathogenic bacteria as well as hepatitis B virus and HIV viruses in a short time (1-2 minutes). In addition, the metal corrosion is weak, harmless to the human body can be used in medical institutions and industries. Mild chlorine deodorant and non-irritant, there is no rejection on use, and fast-acting and completely soluble, there is no residue or scale. The effective chlorine remains for a long time, so that bacteria that have not been completely killed during the treatment process can be killed.

The basic anhydride helps the mixed composition to be well mixed, serves to adjust the pH of the aqueous solution to basic, the time to provide steam by controlling the rate of exothermic reaction of the heating agent reacts with water, the temperature holding time of the aqueous solution To control the back.

The basic anhydrides usable in the present invention can be used as long as they are soluble in water, basic, and solid anhydrides. Preferably, sodium hydroxide, potassium hydroxide, sodium bicarbonate or calcium hydroxide, or a mixed powder thereof can be used. Preferably, sodium hydroxide or a mixed powder of sodium hydroxide and sodium hydrogen carbonate is used.

10 to 1000 parts by weight of aluminum, magnesium, silicon oxide, iron oxide or aluminum oxide, or a mixed powder thereof, based on 100 parts by weight of the disinfectant composition, in addition to the calcium oxide, magnesium oxide or mixed powder thereof, basic anhydride and fungicide It may further include.

In addition, the sterilizing agent composition may further include 100 to 1000 parts by weight of the absorbent with respect to 100 parts by weight of the disinfectant powder. The hygroscopic agent is preferably silica gel and serves to remove moisture to reduce the properties of the heat generating agent in the sterilizing agent composition.

The sterilization pyrogen composition is prepared by mixing (mixing away from moisture) each substance having a particle size of 1 to 100 µm constituting the sterilization composition.

After packaging a certain amount (20 ~ 500g) of the sterilization composition of the present invention with water-permeable natural or synthetic fibers, it can be packaged and sealed with an airtight material to produce a sterilization steam pack.

The airtight material prevents moisture from penetrating the sterilization composition, and the water-permeable natural or synthetic fiber removes the airtight sealing package of the sterilization steam pack, and then allows water to penetrate the sterilization composition for sterilization. .

At this time, in order to prevent the penetration of water into the sterilization composition of the sterilization steam pack, the sterilization composition may be packaged with a water-permeable natural or synthetic fiber, and then packaged and sealed with an airtight material (silica gel) with an airtight material.

When the sterilization steam pack packed with water-permeable fibers is put into a container containing waste water or contaminated water, an exothermic reaction occurs in the sterilization steam pack from which the outer packaging is removed, and the temperature of the water around the sterilization steam pack rapidly increases, and after a predetermined time, steam Will occur. At this time, the sterilization steam pack from which the outer packaging is removed by the generation of steam rises to the surface of the water and the temperature of the water around the surface of the water rises rapidly to provide steam. Therefore, the heat of the exothermic reaction by the exothermic agent heats only water near the surface of the water so that a large amount of steam is generated for a long time with a constant amount of the exothermic agent in the generation of steam. In addition, at this time, the sterilant is also vaporized together with the hot steam to sterilize the external wall inside the container together with the steam. The lower part of the vessel with minimal effect of steam or temperature is effectively sterilized by a disinfectant dissolved in water.

The sterilization steam pack as described above may sterilize and disinfect the contaminated wastewater solution, the inner wall or the outer wall of the container of an unspecified shape, and the wall, but is preferably used for disinfection and disinfection of toilets, public toilets, sinks, washing machines and kennels. Can be.
