Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hypha heat insulating material and a hypha heat insulating material,

The present invention relates to a heat insulating material made of hyphae and a method of manufacturing the same, and more particularly, to a hygroscopic insulating material that has excellent fire resistance and humidity control capability and is harmless to human body and does not require chemical fuel, and a method for manufacturing the same.

Agricultural wastes, which can be used in various directions, are wasted in farmhouses

have. If these wastes are processed by simply finishing without first processing, it will be very profitable for farmers.

Insulation material is a building material that is put in between outer wall and inner wall when building a large temperature difference inside the building.

The insulation is classified into a cold insulation material which maintains a temperature of 100 ~ 500 ℃, a thermal insulation material which maintains a temperature of 500 ~ 1100 ℃, and a fireproof insulation material which is used at a temperature of 1100 ℃ or above.

Commonly used insulating materials include isop pink and polonium.

Isopink is a plastic foam insulation, also known as compressed foamed styrofoam. It has excellent durability and thermal efficiency but is very low in fire resistance. The thickness and area can be adjusted freely, and the strength is also high.

Polonium is a typical heat reflective material made of aluminum. Existing insulation has merely a function of blocking, but the polynium has high efficiency in that it reflects the heat it receives. Because it is thin and flexible, it is easy to construct.

Most of the houses in Korean rural areas are covered with cement and slate. Such houses can be built simply and quickly, but they do not guarantee insulation. Even if I have a hole in the outer wall, I am just living. The residents of rural areas neglect these problems because they are difficult to move because they are farmers, and they are not economically affordable.

In order to solve these problems, it is necessary to have an insulation material that is closely related to their business and is inexpensive. However, existing insulation materials are too expensive to purchase and difficult to construct. Therefore, there is an urgent need for insulation materials that are deeply related to the daily lives of the rural residents, but are inexpensive and satisfy the environment.

On the other hand, it is urgent to develop insulation materials that are inexpensive and environmentally friendly, in order to maximize the use of building materials that cause atrophy and various respiratory diseases, as well as infants and young adults.

If there is an insulation material which is more environmentally friendly than the conventional insulation material and has better heat insulation performance and fire resistance performance and humidity control capability than the conventional insulation material, it can contribute to energy saving.

Korea's dependence on foreign energy is 97%, so energy saving is very important. Considering that about one-third of the domestic energy consumption is in the building sector and most of the cases where KEPCO's blackouts occur are the heating and cooling costs, it can be seen that increasing the insulation efficiency of buildings will contribute to electricity saving.

One of the reasons why a shrinking resin insulation is problematic despite its good efficiency is that it burns well. The cause of death in the case of a fire in a building is caused by suffocation. The urethane or styrofoam insulation material generates a large amount of toxic gas when it is burned. This resulted in the importance of the fire resistance performance of insulation materials and interior materials through cases such as Daegu subway fire case and Sealand fire case. In fact, the styrofoam panel that was used as a building interior material was pointed out as a cause of many toxic gases in the Ilsan Goyang terminal fire accident in May 2014.

Several studies have been conducted on the risk of toxic gases from combustion of styrofoam insulation. According to a study on toxic gases of residential fires (a study on the emission of harmful gases through residential fire rehabilitation experiment, Korea Fire & Fire Association), typical harmful gases generated from sandwich panels are hydrogen cyanide and carbon monoxide, The most toxic hydrogen cyanide, if it is inhaled by a person, will die within 30 minutes if it is above 375ppm.

Insulation materials that are vulnerable to fire are very dangerous.

On the other hand, according to a report evaluating the performance of the insulation material (a study on the humidity control performance of cellulose insulation material), the better the humidity control performance of the insulation material, the better the insulation material. The insulation on the wall has the ability to absorb moisture when the room is wet and to release moisture when it is drying to maintain a constant humidity in the atmosphere.

In fact, this is why the hanok wall of hanok is regarded as environmentally friendly and good material. However, ordinary insulation made of synthetic styrofoam hardly absorbs moisture and has no ability to control humidity in the room.

In this regard, the urgent introduction of insulation materials made of eco-friendly materials is required. However, in the past, there has been no way to manufacture an insulation material having low cost and environment-friendly insulation while having such insulation, fire resistance and humidity control.

Accordingly, the present invention has been made to solve the problems of the prior art, and it is an object of the present invention to provide a fire-fighting apparatus which can be manufactured at low cost using agricultural wastes easily obtainable in rural areas, The present invention also provides a method for manufacturing mycelial and hygroscopic insulators using hyphae, which is safe and harmless due to the generation of toxic gas at the time of occurrence, and which maintains the heat insulation performance at a conventional level and does not cause skin diseases in the human body.

In order to achieve the above object, the present invention provides a method for producing hyphae mycelial insulator and method for producing hyphae, comprising the steps of preparing and sterilizing an agricultural waste medium to be inoculated with mycelium, inoculating mycelium into a microorganism medium, A third step of mixing the microorganism medium cultivated with mycelia with an agricultural waste medium to prepare a mixed culture medium, putting the mixed medium into a mold having a predetermined shape, and drying and sealing the mixture medium However, there is no temporal relationship between the first stage and the second stage.

The agricultural waste medium includes cellulose and lignin components.

In the second step, the culture chamber is preferably provided with an opening through which the air purification filter is inserted, air is blown through the tube by inserting the tube into the culture medium in the culture chamber, and bubbles are generated in the microorganism culture medium.

Meanwhile, the method for manufacturing mycelial adiabatic material according to the present invention may further comprise a fourth step of further adding a chitin component to the mixed medium cultured in the third step and further culturing the same.

At this time, before the chitin component is added, the mixed medium cultured in the third step is mixed with distilled water to form a dough, the medium components are filtered out from the mixed medium in the form of dough, and the chitin component is mixed with the mycelium to prepare a dough desirable.

The present invention has the following effects.

First, since the material excluding the chemical fuel is used, it is eco-friendly and the amount of the harmless and rotting waste is remarkably reduced.

Secondly, because it is made of materials that can be easily obtained in rural areas, it significantly reduces the burden of building materials cost in the construction, maintenance and repair of the farmhouse.

Third, since expensive chemical fuels are not used, they are cost-competitive and safe construction materials because no harmful gas is generated during a fire.

Fourth, while maintaining the conventional level in terms of the heat insulating performance, the heat resistance is superior to that of the conventional heat insulating material, and the humidity control performance of the room is more excellent than that of the conventional heat insulating material.

Fifth, chemical fuels, which are dependent on imports, do not need to be used as raw materials of insulation materials, and the heat insulation performance is better than conventional ones, so that the fuel used for heating can be reduced and the consumption of imported fuel can be reduced nationwide.

Sixth, if hygienic maintenance of the insulation is needed after the construction, the growth of the suspended hyphae is re-grown, so that maintenance can be easily performed without additional material input.

The specific structure or functional description presented in the embodiment of the present invention is merely illustrative for the purpose of illustrating an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention can be implemented in various forms. And should not be construed as limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, a method for manufacturing mycelial heat insulator according to the present invention will be described briefly. Next, a method for manufacturing mycelial heat insulator will be described in detail with reference to the accompanying drawings. Next, a method for testing mycelial insulator performance will be described in detail.

The method for producing mycelial insulator according to the present invention comprises a first step of preparing and sterilizing an agricultural waste medium to be inoculated with mycelium, a second step of culturing mycelium by inoculating mycelium into a culture medium for microorganism, And a third step of mixing the microorganism culture medium and the agricultural waste medium to form a mixed culture medium, placing the mixed culture medium in a predetermined shape mold, drying and sealing the mixture, and culturing the mixture medium. There is no temporal precedence for the step.

The agricultural waste medium includes cellulose and lignin components. Since cellulose is a substance that forms the cell wall of a plant, most of the plant debris such as rice straw, sawdust or dried grass is a substance composed of cellulose component.

In the second step, the culture chamber is preferably provided with an opening through which the air purification filter is inserted, air is blown through the tube by inserting the tube into the culture medium in the culture chamber, and bubbles are generated in the microorganism culture medium. At this time, the bubble can be generated as a bubble generator, and the tube is connected to the bubble generator at one end and inserted into the medium at the other end.

Meanwhile, the method for producing mycelial adiabatic material according to the present invention may further include a fourth step of promoting the growth of hyphae on the mixed medium cultured in the third step and further culturing the chitin with a chitin ingredient added thereto so that the hyphae may grow later.

At this time, before the chitin component is added, the mixed medium cultured in the third step is mixed with distilled water to form a dough, the medium components are filtered out from the mixed medium in the form of dough, and the chitin component is mixed with the mycelium to prepare a dough desirable.

The chitin component can be obtained from the debris of crustacean shells such as crabs and shrimp.

Next, we briefly explain the method for testing the insulation performance of mycelial insulation.

The method for inspecting the insulation performance of the mycelial heat insulator manufactured by the above method is a method for inspecting the insulated performance of a mycelial heat insulator by preparing a specimen of a hyphae insulator of a plate form and a heat insulating material cylinder and forming an opening in the cylinder and inserting a high temperature object inside the cylinder, And inspecting the insulation performance of the hypha insulator by measuring changes in the internal temperature of the cylinder and the external surface temperature of the specimen.

Wherein said hot object is preferably boiling water.

Hereinafter, a method for manufacturing hypha insulator and a method for testing it will be described in detail with reference to the accompanying drawings.

There is no particular limitation on the type of hypha used for the production of hyphae insulator. It is more preferable that the hypha is easy to obtain as an inexpensive price. Mushroom mycelia are generally suitable.

Mushrooms are largely divided into mycelium and fruiting bodies. Mycelium is a collection of cells that act as nutrients for fungi, such as mushrooms. They grow the fruiting body in a way that spreads the spores. In order to grow fruiting bodies, growth of fruiting bodies that absorb nutrients is essential. So the mushroom spreads the mycelium wide enough and starts to make fruiting bodies. Mycelium is an organ that absorbs nutrients directly, so it has a very thin and long pipe structure, which consists of a combination of cells one by one. When cells are formed, their cells are made of chitin.

Among the mycelia forming mushrooms, it is preferable to grow relatively widely in Korea especially in winter, and it is not necessary to pay much attention to control during cultivation, and it is preferable that the growth is relatively fast. For example, P.ostreatus is a representative species among 30 species in the oyster.

Hereinafter, an embodiment in which hyphae mycelial insulator is produced by using hyphae mycelium will be described. However, since the heat insulator made of mycelium shares the same characteristics, the following embodiments are applicable to the heat insulators made of different types of hyphae.

Two types of media are required for the production of insulators using mycelium. One is a sawdust-shaped medium to be inoculated with bacteria. In addition to sawdust, agricultural wastes including hay, dried grass, rice straw, and the like, which contain cellulose and lignin components, The photograph of Fig. 2 shows the agricultural waste which is the raw material of the agricultural waste medium.

The other medium is a microorganism medium used for culturing microorganisms, commonly known as LB Broth.

Agricultural waste media must undergo an initial sterilization process so that the mycelium to be cultured later can be rapidly cultured. Sterilization is accomplished by pressurizing the agricultural waste medium with hot water at 121 ° C for 15 minutes. However, temperature conditions and sterilization time can be changed as needed.

Prepare LB broth medium separately from agricultural waste medium. Cultivation of mycelium is carried out on LB broth medium, then cultivated again by mixing appropriate amount of LB broth medium with mycelial cultivation waste medium. Therefore, it is not necessary to prepare agriculture waste badges first.

Since the production of the LB Broth medium itself is a well-known technology, a detailed description thereof will be omitted here. The LB Broth medium is selected because it contains abundant essential amino acids and vitamins for microbial cultivation. However, LB Broth medium can be selected as a medium for initial cultivation since it can be selected if the medium is capable of supplying the initial nutrition to the mycelium in addition to LB Broth There is no.

The LB Broth medium is sterilized by first applying pressure at 121 ° C to the water bath. The sterilized medium is allowed to cool to room temperature. The first step is completed by preparing two types of sterilized media.

The second step is a step of inoculating mycelium with LB Broth medium in the prepared medium.

FIG. 3 is a conceptual view showing the structure of a culture room in which LB broth medium in which mycelium is inoculated is placed.

 The LB Broth medium is first inoculated with the mycelium of solid state, and then the LB Broth medium inoculated with mycorrhizae is put into the culture chamber. As shown in FIG. 3, a bubble generator is inserted into the culture chamber to connect the bubble generator and the culture medium, and bubbles are generated in the culture medium to supply oxygen.

At this time, the supplied oxygen is supplied to the opening formed in the culture chamber. In order to supply the sterilized oxygen, an air cleaning filter may be installed in the opening shown in the upper right of FIG.

Culturing in LB broth medium performed in the culture room is carried out for a period of 7 days.

Thus, when the primary culture is performed in LB broth, the second step is completed.

In the third step, the mixed medium is first prepared by mixing the cultured LB Broth and the sterilized sawdust medium in a ratio of 1: 2.

Next, the mixed medium is put into a mold made of acrylic, and the entrance is covered with a thin paper. At this time, the thin paper covering the inlet is soaked in water to prevent the mixed medium from drying. Dry soaking seal is achieved by blocking the mold opening with a thin sheet of paper so wet.

Cultivation of the mixed medium is carried out for 7 to 10 days.

Fig. 4 is a photograph showing a culture medium cultured in a mold. There is no restriction on the shape of the mold, and the shape of the mold is prepared in advance so that it can be cultured in the required shape.

4 is a rectangular frame and the right photograph is a circular frame. Fig. 5 is a photograph showing mycelium grown to fit a circular mold.

Since hyphae themselves can grow continuously, they are dried at high temperature to remove hygienic seals and stop hyphae growth.

The mycelium grows fully to the shape of the mold, and the third step ends. Hereinafter, the process of adhering the mycelial heat insulation material to the finish material so that it can be actually used as a heat insulation material is a well-known technique and will not be described.

On the other hand, if the stomatal insulation material is actually applied, the medium will be used for growth of mycelium and no longer grow. Therefore, it is necessary to apply a high energy source while slowing degradation than cellulose or lignin.

This is because it is much more efficient to utilize the self-recovery ability of mycelium rather than injecting the stiffener when maintenance is required due to cracks even after hyphae insulator construction. However, in order for self-healing ability to be demonstrated, a further energy source is required because the mycelium growth is required.

As such an energy source, a chitin component can be preferably applied. FIG. 6 is a photograph of mycelium growing in a chitin-type chitin medium and a chitin medium containing a chitin component. The photo on the left is a kitten badge.

In the preparation of the chitin medium, first, the solid state medium after the third step is mixed with distilled water to form a dough. Then, filter the dough-shaped medium formed into the sieve so that the medium does not come out but the mycelium can escape.

Thereafter, the mixture is mixed with a solution containing crab shell powder containing chitin and a sieve-filtered mycelium to form a dough-like form. Then, the mixture is incubated at a room temperature for one week at a low light level. This is the fourth step.

Therefore, the above-mentioned panel fabrication for forming the above-mentioned heat insulating material proceeds after the fourth step when the fourth step is added.

Thus, the method for manufacturing mycelial heat insulator is completed.

Hereinafter, the insulation test, the fire resistance test and the humidity test method of the mycelial heat insulating material will be described in detail. First, the insulation test method will be described.

For reference, all tests are conducted not only for mycelial insulation but also for other insulation sold in the market, and compare the results. The comparison is the two most commonly used insulation materials, isoprene and polonium.

Basically, the index indicating the efficiency of the insulation is the insulation performance, which depends on how much heat is passed through the insulation per unit time. The insulation efficiency can be measured by comparing the heat transfer through the insulation with the temperature controlled or the temperature change of the two spaces blocked by the insulation.

First, you need to prepare a sample of insulation. The schematic test method is a method of replacing a part of one side of an insulating material cylinder with a sample of a certain size and observing the temperature change by giving a temperature difference between the inside and the outside of the insulating cylinder.

Insulation samples are prepared in a plate with a certain area and shape. The reason for preparation in the form of a plate is that an opening is formed in the cylinder of the heat insulating material and the opening is closed with a heat insulating material sample in place of the heat insulating material forming the cylinder.

The mycelial insulator specimens used in the experiment and the isoprene and polonium specimens to be compared are all made to the same size.

Prepare a tube of insulating material as well as a specimen. The tubular heat insulating material may be an ordinary styrofoam material whose heat insulating performance is well known. And the cylinder may be in the form of a regular box. At this time, a thermometer is installed to measure the temperature inside and outside of the cylinder.

The temperature inside the cylinder should be punctured by a hole in the lid, and a thermometer should be inserted and sealed to prevent the formation of a hole. A thermometer placed outside the cylinder is used to measure the room temperature of the environment in which the experiment is being conducted.

At this time, a separate infrared thermometer is installed to measure the surface temperature of the heat insulating material replacing a part of the cylinder.

An opening is formed in a part of the cylinder and the opening is closed with a heat insulating material specimen.

At this time, in order to be able to seal the cylinder with the heat insulating material specimen, a wood rod is cut in the opening so that the heat insulating material can be seated in the opening as shown in FIG. 7 (a), so that the heat insulating material specimen is not dropped when the heat insulating material specimen is inserted into the hole. This also has the effect of preventing the heat from escaping through the gap. Then, the specimen is inserted into the opening of the cylinder.

Fig. 7 (a) is a photograph showing an opening formed on one surface of the cylinder and a photograph showing a specimen of hypha insulator, and Fig. 7 (b) is a photograph showing a state in which the specimen is insulated by inserting the specimen of hypha insulator into the opening of the cylinder.

When the inside and outside temperatures of the insulating material are different from each other for the insulation test, hot air such as a dryer may be generated. However, even if there is only a slight crack, the heat is released through the cracks, To make the temperature inside and outside the cylinder different.

Put the hot water in a separate container and put it inside the cylinder. In this case, because the increased humidity caused by the hot water inside the container can affect the condition of the sample, the vinyl wrap prevents the entrance of the water container. This is because moisture can affect the adiabatic test.

Place the container with hot water inside the cylinder and wait for 1 minute to warm up the inside of the box.

After the box is preheated, the temperature change is measured over time. The temperature is measured at room temperature, box internal temperature, and external surface temperature of the insulation sample for 900 seconds (15 minutes). The measurement time can be changed as needed.

8 is a graph showing the results of the test results of the heat insulation performance. The graph shows the results of measuring the surface temperature of a heat insulating material specimen fitted to the tubular body after raising the internal temperature of the tubular body of the heat insulating material to about 60 ° C.

In FIG. 8, the blue line in which the rhomboid shape is expressed at a constant interval is the surface temperature of the styrofoam constituting the cylinder itself, and the red line in which the rectangle expressed by the temperature eye is the regular interval is the surface temperature of the isoprene sample , The blue line with a constant interval of triangles denoting the temperature poly is the surface temperature of the polynium sample, and the purple line with the X self interval, expressed as the temperature mush, is the surface temperature of the hyphae.

The isoprene and polynium specimens reached a stabilized temperature of about 33 ° C in 200 seconds, while sanitary insulation took about 700 seconds to reach a stabilized temperature of about 33 ° C. This indicates that the heat transfer through the hyphal insulation is three times slower than the conventional insulation.

The fact that the amount of heat flow through the heat insulation per unit time is small means that the effect of suppressing the temperature change is great, so that it is concluded that the efficiency of the insulation is good.

After a certain period of time (about 11 minutes in the graph), the surface temperature of all the thermal insulation materials used in the experiment remained constant (about 33 ° C) without any significant change.

Fig. 9 also shows the results of the heat insulation performance test.

According to the test results, the ability to keep the temperature difference between the outside and the inside constant can be said that hyphae insulator has similar performance to other insulators.

Next, the fire resistance performance test will be described.

First, after each test specimen is made long with a certain width, a method of comparing the fire resistance performance by measuring the time taken until the fire is turned off and the burned distance are measured after igniting the fire at one end of the specimen.

Specifically, heat insulation specimens are placed on two rods and heated with an alcohol lamp for 5 seconds at one end of the specimen. If the insulation is on, stop heating and continue heating if it does not catch fire. Then, after the fire is extinguished naturally, the length of the insulation is measured.

10 (a) is a photograph showing the hyphae insulator specimen, the polynium specimen and the isoprene specimen in order from the left, and Fig. 10 (b) is a photograph showing the fire resistance test being carried out.

11 is a photograph showing a process of burning a specimen by an anti-fire test using a gas torch, not an alcohol lamp. From the left are the polynium specimen, the isoprene specimen, and the hyphae insulator specimen.

Polyne specimens take about 8 minutes to burn all of the specimens. And once it catches fire, it is burned to the end without spontaneous digestion. Isop pink melts when it reaches the fire and falls out of the base, so it is difficult to measure the burned distance. Finally, mycelial insulation does not catch fire even if it is heated for more than 30 seconds by an alcohol lamp.

A gas torch can be used to perform a slightly stronger fire test.

As a result of the gas torch test instead of the alcohol lamp, the polonium and isoprene are burned as soon as they reach the fire, but the mycelial insulation does not catch fire even after heating for 10 minutes.

The fire resistance test using a gas torch is shown in Fig.

Next, the test method and results of the humidity control performance will be described.

According to a report evaluating the performance of insulation materials (a study on the humidity control performance of cellulose insulation material - a spring conference meeting of the Architectural Institute of Korea), the better the humidity control performance of the insulation material, the better. The ability of the insulation to absorb moisture when the room is wet and to keep the humidity constant in the atmosphere by discharging moisture when it is dry is the humidity control ability.

In fact, this is why the hanok wall of hanok is regarded as environmentally friendly and good material. However, ordinary insulation made of synthetic styrofoam hardly absorbs moisture and has no ability to control humidity in the room. On the other hand, hyphae insulator has a hygroscopic effect because it has a structure in which hyphae are intertwined, so that there is a lot of space inside the insulator and the characteristic of being able to absorb moisture in the characteristic of hyphae.

There is no limitation on the setting of the humidity condition, and in the humidity test example of the present invention, how much moisture the insulating material can absorb in the saturation humidity condition in the air is measured and the humidity test is performed. Measuring the rate at which the specimen absorbs moisture in this state can be used to determine the extent to which the insulator can absorb moisture.

First, prepare the specimens for the test preparation in the same manner as the insulation test described above, and prepare the same cylinder as the insulative material in the insulation test.

Next, as a method of exposing the heat insulating material to humidity, high temperature water is put into the inside of the cylinder, and the lid is closed and waited.

When the humidity of the inside of the cylinder reaches 99% due to the steam, the cover of the cylinder with the heat insulating material specimen is covered as in the case of the insulation test.

Cover the cylinder lid and after a certain time (1 minute), remove the specimen from the lid and measure the temperature and moisture content. The water content is measured at several sites of a specimen and averaged. The time required for the measurement does not need to be included in the water vapor exposure time of the specimen. I did.

Fig. 12 is a photograph of the specimen undergoing the humidity test, and Fig. 13 is a chart showing the results of the humidity test.

As shown in Fig. 13, the hyphae insulator rapidly absorbed water in the early stage and absorbed about 1/6 of the specimen mass after 30 minutes. Styrofoam insulation isoPink specimen is very much higher than the 15% moisture content increase in 30 minutes. Polonium specimens do not absorb any moisture.

As a result, the methods and results of the humidity test of the hypha insulator were also examined.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
