Rubber Chip Treated With Pyroligneous liquid and Bio Chip Including the Rubber Chip and Yellow Clay}

The present invention relates to a rubber chip treated with wood vinegar, and a biochip containing the rubber chip and loess.

At present, the development of the automobile industry increases the number of waste tires by more than 2 million every year. On the other hand, waste tires are left unattended or simply incinerated because there is no facility to properly dispose or recycle them. Accordingly, environmental pollution and waste of resources due to industrial wastes such as waste tires are emerging as social problems all over the world.

Accordingly, various technologies for manufacturing construction materials such as concrete blocks, plywood aggregates, floorings, artificial grass, sidewalk blocks, and wall interior materials are made using appropriate properties such as impact resistance and chemical resistance of waste tires, which are industrial wastes. Is being developed.

Among them, conventional sports facilities such as soccer fields and golf courses have installed grasses that have been transferred to grass, so the roots of grass roots on the ground are low, and the life of the grass is short. It was hard.

As a solution, semi-permanent artificial turf has been developed using waste tires. In the case of the artificial turf, the convenience of construction and management, the air permeability and drainage of the soil is improved, and the elasticity of the international standard for the sports facilities (FIFA standard buffer effect 51-70%) can be obtained.

However, recently, in the case of artificial turf using waste tires, in the summer when the temperature exceeds 25 degrees Celsius, not only does the tire burning smell from the waste tires occur, but also due to the characteristics of sports facilities, it is fatal to the human body due to friction caused by pressure. However, as it is discovered that waste tire dust containing a large amount of carcinogens such as benzene is generated, there is a debate about the harmful effects on the human body.

In recent years, efforts have been made in Europe to replace artificial turf fields with natural grass fields or to develop eco-friendly stadiums using new construction methods.

On the other hand, wood vinegar refers to a liquid that is obtained by liquefying the smoke from the charcoal burning process (carbonization process) by the cooling device, and then matured and purified to remove toxic and harmful substances sufficiently. Wood vinegar is called wood vinegar because it contains a large amount of various organic acids such as acetic acid as its main ingredient, and wood vinegar contains a large amount of minerals such as calcium, vitamins B1, B2, phenols, aldehydes and alcohols in addition to acetic acid. .

Recently, it has been found that the organic acids contained in the wood vinegar give beneficial results to the body, such as metabolic processes and immunity, and various studies have been conducted to completely remove harmful ingredients such as methanol and phenol from wood vinegar and then use them in cosmetics or functional drinks. It is done.

On the other hand, ocher is largely used in two senses. Firstly, it is known that it is a pale yellow to yellow gray silt loess, which is carried and deposited by wind, and is homogeneous and 0.05 ~ 0.005mm silt. ) Contains more than 50% of carbonate, which is widely distributed in China, Europe, and North America.

Another meaning of ocher is commonly used in Korea, and refers to the light and dark black soil (weathered soil) formed during the process of changing the rock to yellow to yellow brown soil by weathering.

Ocher consists of chemical compositions such as iron, silica, alumina, magnesium, sodium and lime, and mineral compositions such as quartz, feldspar, mica and carbonate minerals. In addition, ocher has a viscous force that is not easily broken because it contains a large amount of calcium carbonate, and when water is added, it turns into clay.

Microorganisms, such as moss, fungus, radiation bacteria, bacteria, etc. contained in the ocher are responsible for decomposing organic substances to enhance the effect of increasing biological immunity. Among them, the catalase enzyme dilutes the toxin called lipid peroxide, which causes aging in the body's metabolic process, and the diphenol oxydase enzyme improves the oxidizing and degrading power of microorganisms and enzymes in loess. Protease enzyme acts to purify the protein by hydrolyzing it to amino acids when the nitrogen in the protein is mineralized.

In particular, since yellow soil absorbs and radiates large amounts of far infrared rays, which are effective for living organisms, the loess is active in physiological functions of cells in the human body, and generates heat energy to adsorb and remove harmful substances such as heavy metals, thereby reducing pain. In addition, it is possible to obtain a sterilization effect and air purification effect to kill mold and red tide.

Recently, in addition to medicines for treating human diseases using ocher, attempts have been made to develop cosmetics or feeds.

The present invention provides a rubber chip treated with wood vinegar to remove rubber odor and harmful components.

In addition, in the present invention, by mixing the rubber chip treated with the wood vinegar solution with ocher and eco-friendly adhesive, to effectively suppress the generation of harmful substances, to provide a biochip that can radiate a large amount of far infrared rays effective to the living body. do.

Hereinafter, the present invention will be described in detail.

First, the present invention provides a rubber chip treated with wood vinegar solution.

The wood vinegar can be anything that is liquefied in the process of burning charcoal, in particular, by cooling the smoke generated when burning charcoal using raw oak raw materials, using only the liquid extracted from the smoke temperature of 80 ~ 150 ℃ desirable. If the smoke temperature is 80 ℃ or less, the water content is high, and if it is 150 ℃ or more, the harmful ingredients such as tar are high. Therefore, a cooling device is installed when the smoke temperature reaches 80 ℃, and collection is performed when the temperature reaches 150 ℃. You must stop to get a good quality vinegar.

The obtained liquid is placed in an acid-resistant container and left to stand for about 3 to 24 months, and separated into a 15-20 volume% light oil layer, a 50-60 volume% wood vinegar layer and a 20-30 volume% tar layer. Among them, only the portion of the wood vinegar layer, which is the middle layer, is selected and removed, and then some of the harmful substances are removed. Then, the obtained wood vinegar layer is thermally decomposed using a steam distillation method, leaving only the alkaline substance and aged to obtain purified wood vinegar. In the present invention, it is possible to use general wood vinegar before purification, preferably using purified wood vinegar.

At this time, the component content of the general wood vinegar before the separation of the harmful substances and the purified wood vinegar after pyrolysis showed that the normal wood vinegar before the separation of the hazardous substances was an amber liquid containing a trace amount of tar and phenol such as phenol. Purified wood vinegar obtained by removing the harmful components and pyrolysing becomes a clear liquid similar to pale yellow vinegar containing a large amount of eosinic and organic acids.

In addition, the rubber chip is a rubber chip pulverized waste tires that are treated as general industrial waste. For example, at room temperature, waste tires, which are industrial wastes, are cut and pulverized to remove iron cores and fibers, and then a coarse powder of 10 to 30 mesh is prepared using a cryogenic process using liquid nitrogen as a refrigerant. Manufacture. Subsequently, the crude powder is added to a freezing tank (-120 ° C.) to freeze and pulverize at a glass temperature (Tg = −68 ° C.) or less to prepare a rubber chip having a particle size of 80 to 120 mesh or less.

In the present invention, after immersing 5 ~ 10kg of the 80 ~ 120 mesh rubber chip in 1L of purified wood vinegar solution, and aged for 24 to 30 hours at room temperature to prepare a rubber chip treated with wood vinegar solution. At this time, when the aging time is shorter than 24 hours, the removal effect of harmful components in the wood vinegar is low, and when longer than 30 hours, the hardness of the rubber chip increases.

Thus, the rubber chip treated with the wood vinegar of the present invention can not only remove most of the harmful components that could not be removed even in several stages of the purification process, it can also significantly reduce the burning smell of the rubber. In particular, when comparing the removal rate of the harmful components before and after the treatment of the rubber chip using the wood vinegar, it was shown that the most harmful component and odor removal effect when immersed about 8 kg of rubber chip for 24 hours for 1L of wood vinegar solution.

In addition, the present invention provides a biochip for building materials manufactured by mixing the rubber chip treated with the wood vinegar and ocher and eco-friendly adhesive, preferably an eco-friendly adhesive.

In this case, the loess is collectively referred to as sedimentary soil or weathered residual soil, and means ordinary loess. In particular, it is preferable to use clay having a grain size of 0.005 mm or less and earthy and blackish soil including coarse and neutral components having a particle size of 0.02 to 0.05 mm. The loess is a chemical raw material 60 to 65 parts by weight of silica, 10 to 13 parts by weight of alumina, 5 to 6 parts by weight of iron, 8 parts by weight of lime, about 2 parts by weight of magnesium and sodium And 1.5 parts by weight of cali, minerals include 60 to 70 parts by weight of quartz, 2 to 10 parts by weight of feldspar and mica and 5 to 35 parts by weight of carbonate mineral, based on the total weight of minerals. Silt includes heavy minerals such as hornblende, apatite, biotite, chlorite, citrine, verdite, garnet, arsenite, rutile, quartzite, cruciate, tourmaline and zircon. In the embodiment of the present invention uses raw ocher manufactured by Hana Co., Ltd. manufacture.

In the present invention, it is preferable to use the raw ocher made of the above ingredients after baking at 800 to 1000 ° C. If using raw ocher, the manufactured biochip has a disadvantage of being easily broken by impact, heat or water, whereas when using high-temperature baked ocher, a biochip having improved efficacy such as impact or durability against water is used. You can get it. In addition, since yellow soil is excellent in the removal of harmful substances, sterilization effect to kill mold and air purification effect, when used together with the rubber chip treated with the wood vinegar solution of the present invention further reduces the emission effect of harmful components, It is possible to manufacture biochips with improved water retention and thermal conductivity due to the ocher function.

In addition, the biochip containing the rubber chip treated with ocher and wood vinegar of the present invention, even if immersed in water for more than 24 hours, to prevent it from being released or broken and deformed, an environmentally friendly adhesive, for example, It is preferable to further include a bond (Model NO. Mx-300, mx-400), and may further include charcoal to further reduce the harmful component release effect.

The biochip of the present invention preferably contains 0.001 to 0.02 parts by weight of ocher and 0.008 to 0.2 parts by weight of an environmentally friendly adhesive based on 100 parts by weight of the biochip. If the amount of loess is 0.001 parts by weight or less, the rubber chips are not sufficiently coated by the loess, and thus the effect of releasing harmful components or water retention is low, and when the amount is more than 0.02 parts by weight, the rubber chips are overcoated with loess and the elasticity is lowered. This results in a problem that the biochip diameter increases. In addition, when the content of the environmentally friendly adhesive is lower than 0.008 parts by weight, the adhesive strength between the rubber chip and the loess is lowered, causing a problem that the biochip is broken, and when higher than 0.2 parts by weight, an excessive use of the adhesive occurs. At this time, the diameter of the biochip of the present invention is preferably 0.5 ~ 3mm.

The biochip of the present invention is added to the rubber chip treated with wood vinegar and ocher and eco-friendly adhesive sequentially, then mixed for 3 to 4 hours at 30 ~ 50 ℃, 30 ~ 50 ℃, preferably at 10 ℃ 40 Prepare by drying for ˜11 hours. At this time, when the drying and the reaction temperature is 30 ℃ or less, the adhesive effect of the eco-friendly adhesive is low, the biochip of a uniform size is not formed, and if it exceeds 50 ℃, the eco-friendly adhesive melts to form a biochip.

As described above, in the case of the rubber chip treated with the wood vinegar of the present invention, the effect of preventing the occurrence of harmful components and odor generated even at high temperatures is excellent (see Experimental Example 1 below). In addition, biochips coated with rubber chips treated with the wood vinegar of the present invention are yellow soil-coated biochips, and since they contain a large amount of loess, they have superior adsorption effects for adsorption and removal of harmful substances such as antibacterial and heavy metals. It can improve human stability. In particular, the biochip of the present invention has excellent moisture preservation effect due to loess, and high thermal conductivity, so that the temperature change is not large. For example, when the biochip coated with ocher coated rubber chip of the present invention is used in artificial turf, 60 degrees of elasticity is suitable for the value indicated by the international standard (51 to 70% of the FIFA standard) even when freezing. It can maintain ~ 65% elasticity to prevent injuries of players. In addition, since the loess biochip of the present invention emits a large amount of far infrared rays from the loess containing the loess, when walking barefoot on the artificial turf coated with the loess biochip, it brings about a bactericidal effect by far infrared rays and acupressure effect. Improve blood circulation.

In addition, when the biochip of the present invention is crimped and cured in a mold and used as an interfloor floor or a building material for multi-family housing, it is an eco-friendly product that does not generate harmful components, and also has high durability and weather resistance, and a high degree of elasticity. Excellent removal effect. Moreover, in the case of the building material of the present invention, the interlayer noise reduction effect is excellent, so that the interlayer of the present invention on the lightweight foam concrete instead of the flooring method, which was conventionally performed in the order of concrete sleeve / lightweight foam concrete / buffer / finish mortar / floor finish. Since only the flooring material can be installed, the floor finishing material can be directly formed on the upper part, thereby simplifying the flooring construction process and reducing the construction cost. In particular, when forming a specific groove, such as a cross-shaped groove to allow the heating or hot water pipes to pass through the upper part of the tile during manufacture of the flooring, it is possible to simplify the subsequent process.

In addition, when the external flooring material using the biochip of the present invention is applied to the upper part of the building (or the rooftop) or the outer wall, it is possible to reduce the cooling cost because the temperature inside the building can be prevented from rising by blocking direct solar heat in summer. In addition, in winter, it is possible to prevent the emission of temperature from the inside of the building, thereby achieving the effect of reducing the southern costs.

As described above, the present invention comprises a rubber chip treated with wood vinegar solution to reduce the occurrence of odor, and the rubber chip, ocher and eco-friendly adhesive, to produce a biochip for building materials or exterior flooring improved moisture preservation effect and thermal conductivity Can be.
