Description

TECHNICAL FIELD The present invention relates to a functional polymer plastic containing fullerene and phytoncide, and a method of preparing the functional polymer plastic,

The present invention relates to functional polymer plastics containing fullerene and phytonchide, and a method for producing the same. More specifically, the present invention relates to a functional polymer resin containing fullerene and phytoncide, Resin, wax, and the like, followed by compression injection molding, and a method for producing the functional polymer plastic.

Petroleum-based plastic materials are widely used for various molded products, packaging materials, industrial materials and consumer goods due to their excellent physical properties, various functions, and low prices. However, these products are not decomposed naturally in a proper period and cause serious environmental pollution , Bisphenol-A, and other environmental hormones.

As a method for treating such petroleum-based plastic wastes, conventionally, methods such as landfill, incineration and recycling have been adopted. However, due to problems with each of them, degradable plastics which can be completely decomposed into water, carbon dioxide, methane gas, etc. within several months to several years (Bio-Degradable Plastic), which is decomposed by microorganisms and enzymes, and photochemical and thermal reactions caused by solar radiation and sunlight. (Photo-Degradable Plastic) where plastic decomposition occurs due to chemical bond cleavage caused by chemical bond cleavage, Oxidation-Degradable Plastic where plastic decomposition occurs due to the influence of temperature, And a < RTI ID = 0.0 > hydrolysis < / RTI > Hydrolytically-degradable plastic, biodegradable, photodegradable plastic, or complex decomposable plastic thereof, has been actively studied. To reduce the use of petroleum-based plastics, vegetable wastes, For example, there has been developed a technique of mixing powders such as coffee, rice husks, and wheat husks into plastics, but the physical properties of the final product are deteriorated and recycling after use is not feasible.

Phytoncide is a mixture of chemicals released by plants to combat pests, fungi, and germs, and has antimicrobial and antimicrobial properties. Phytoncide, released from perilla trees, has excellent antibacterial and natural healing power The undiluted solution extracted from cottonwood and the fragments of wood wool are applied to treatment of patients related to the atmosphere such as indoor environment purification and atopy (Korean Patent No. 10-1152684, No. 10-1305384, No. 10-0930317).

Phytoncide is not a single component but a mixture of components with different melting points and solubilities of more than 50 kinds, so it is very difficult to control the components and the release rate. It is difficult to control the release and release rate depending on the ambient environment such as temperature and humidity There is a problem that the direction density of phytoncide is excessively high, which is harmful to the human body.

For this reason, it is required to develop a product capable of maintaining phytoncide performance while easily storing phytoncide and continuously emitting phytoncide.

Fullerene is usually referred to as a third carbon isomer, because it has a different form of carbon, such as graphite or diamond, or graphite or diamond. Fullerene has a carbon ring in which carbon (C) atoms are arranged in a pentagonal or hexagonal shape. These carbon rings are combined in a substantially spherical shape to form a hollow. Generally, fullerene has a carbon number of C60 to C80 or greater. Fullerene, in its structural form, has the shape of a soccer ball, or a shape such as a soccer ball-like shape, and has a hollow-phase structural characteristic. Fullerene has excellent physical and chemical properties due to the above-mentioned carbon ring arrangement and specific structure of the hollow. Specifically, fullerene has a variety of useful physical and chemical properties such as strong antioxidant, adsorptive, catalytic (decomposability of adsorbed material), bactericidal power, electromagnetic wave absorptivity, electrical conductivity, and in some cases higher than diamond Its application value is high.

Generally, fullerene is produced by artificially synthesizing carbon black or graphite as a raw material through an arc discharge method or a continuous combustion method, or by extracting it from natural minerals. Some natural minerals contain fullerene or similar fullerenes. From these natural minerals, fullerene was extracted by using an electrochemical method and a polar solvent extraction method (JP-A-7-315987).

Fullerene is a powerful natural antioxidant that increases the immunity of humans to many diseases. It absorbs various pollutants on the earth in a porous structure, purifies water and air, and decomposes adsorbed contaminants by themselves. Pseudomonas aeruginosa, Staphylococcus aureus, and other harmful bacteria. It is widely used in health functional products because it cuts harmful electromagnetic waves and emits a large amount of far infrared rays. Currently, most of the methods that are widely used include processing gypsum containing a large amount of fullerene into a brick form, stacking it on a wall or floor for use in construction, or finely crushing the water into a water bottle for drinking or finely grinding, It is limited to simple use (Korean Patent No. 10-1515534, and Korean Patent No. 10-1633302).

For this reason, it is required to develop a new material that can maintain the unique performance and function of Fullerene while being easy to use and a product using the new material.

The natural minerals may be selected, for example, from clay minerals and shungite minerals. That is, the natural minerals may be pure whiteness minerals or pure natural minerals may be mixed with other natural minerals. The pure-earth mineral is mainly composed of a silicon compound (silicate) such as silicate, and has a high content of carbon components, particularly a content of fullerene, which is useful in the present invention. That is, the pure minerals contain 25% or more, more specifically 25 to 50% by weight of fullerene.

The mineral powders can be prepared by pulverizing natural minerals containing fullerene, preferably pure minerals, to an appropriate size. Natural minerals can be ground by widening the surface area, so that the extraction rate of carbon components in the extraction process can be improved. For example, it may be milled to a size of 200 to 400 mesh and is preferably milled to a size of 300 mesh. At this time, if the particle size of natural minerals is too small, it may be difficult to handle, and if it is too large, the extraction rate of carbon components may be lowered.

< Experimental Example >

<1-1> Biodegradability test

The biodegradability of the prepared polymer pellets was measured.

For the measurement of biodegradability, tests were conducted according to KS M ISO 14855-1 (Determination of aerobic biodegradability and decay of plastics under composting conditions - Determination of carbon dioxide generated by titration).

The test was carried out in dark or diffused light, with no gas that could maintain a constant temperature of 58 ± 2 ° C and inhibit microbial activity. Standard composts complying with KS M ISO 14855-1 were used and compost was produced in a properly operated aerobic composting plant and used sufficiently aerated compost as inoculum. The total dry solids content should not exceed 50-55% of the wet solids content and the volatile solids content should not exceed 15% of the wet solids and 30% of the dry solids content. The water content was maintained at approximately 50% and the inoculum was allowed to generate 50 to 150 mg of carbon dioxide per gram of volatile solids during the first 10 days of the test. TLC (thin film chromatography) grade cellulose having a particle size of 20 mu m or less was used as the standard material used for the test.

0.4 N potassium hydroxide aqueous solution and 2.0 N barium chloride aqueous solution were mixed at a ratio of 5: 1 in order to collect carbon dioxide generated in the composting process. To capture the captured carbon dioxide, the capture bottle was separated at regular intervals. The separation time was determined according to the rate of biodegradation. The separated collecting bottles were sufficiently agitated, and then 12 mL was taken, placed on a magnetic stirrer, and 2 to 3 drops of phenolphthalein aqueous solution were dropped. The solution was titrated with a 0.2N hydrochloric acid aqueous solution until the pink color became colorless while stirring.

The end of the test was incubated for 6 months until reaching a stasis. After the end of the test, the biodegradability was calculated. The biodegradability was calculated as follows. First, the theoretical carbon dioxide emission was calculated, the generated carbon dioxide was calculated, and the biodegradability was calculated according to the following formula.

(1) Calculation of theoretical CO2 emission

ThCO ₂ = M _TOT x C _TOT x 44/12

M _TOT : Amount of total dry solids in the test material added to the compost at the start of the test (g)

C _TOT : Percentage of organic carbon contained in the total dry solids of the test substance (g / g)

44, 12: molecular weight of carbon dioxide and atomic weight of carbon

(2) Calculation of generated carbon dioxide

Xmg of CO ₂ = 44 x 1/2 x (20 - mL HCL) x 0.2 moles

The amount of hydrochloric acid used in the titration with 0.2N hydrochloric acid is taken as mL HCL and the amount of carbon dioxide generated is calculated using the above formula.

(3) Calculation of biodegradability

D _t = [(CO ₂ ) _T - (CO ₂ ) _B / ThCO ₂ ] × 100

(CO ₂ ) _T : Cumulative amount of carbon dioxide generated from the composting container containing the test substance (g)

(CO ₂ ) _B : Average of the amount of carbon dioxide accumulation from the inoculation vessel (g)

ThCO ₂ : Theoretical amount of carbon dioxide generated by the test substance in the container (g)

As a result, in the process in which cellulose (standard test substance) was 37% decomposed for 18 days, the polymer plastics produced in Examples 1 to 3 decomposed to about 33 to 35%, respectively, The polymer plastics showed about 25 to 28% decomposition and somewhat lower biodegradability. On the other hand, the polymer plastics prepared in Comparative Examples 1 and 2 were decomposed by about 22 to 23%, respectively, showing lower biodegradability.

<1-2> Maximum bending load test

The maximum flexural load (unit N) of the prepared polymer pellets was measured.

Flexural loads were measured according to the American Society for Testing and Materials (ASTM) method.

As a result, the polymer plastics produced in Examples 1 to 3 exhibited a maximum flexural load of about 895 to 910 N, respectively, and the polymer plastics produced in Examples 4 to 5 showed about 805 to 815 N, respectively , And the polymer plastics prepared in Comparative Examples 1 and 2 exhibited about 765 to 775 N, respectively.
