Description

폐섬유질을 포함하는 생분해성 용기Biodegradable container containing waste fiber
본 발명은 폐섬유질을 포함하는 생분해성 용기에 관한 것으로, 더욱 자세하게는 폐기되거나 버려지는 폐섬유질이 포함된 생분해성 소재에 결합력을 갖도록 전분을 배합하여 일정강도를 가지면서, 일정기간 사용 후 버려질 때 토양이나 자연에 전혀 무해한 용기에 관한 것이다.The present invention relates to a biodegradable container containing waste fibers, and more particularly, to combine the starch so as to have a binding force to the biodegradable material containing waste fibers discarded or discarded, having a certain strength, to be discarded after a certain period of use When it comes to containers that are completely harmless to soil or nature.
산업의 발전과 함께 소득 수준의 증가 및 생활 환경의 변화에 따라 식품의 다양화와 함께 일회용 식품 용기의 수요가 급증하고 있다.In line with the development of the industry, the demand for disposable food containers is rapidly increasing along with the diversification of foods as the income level and the living environment change.
상기와 같은 식품 용기로 도기류나 유리제품을 사용하는 경우에는 보관 및 장소확보가 어렵고 높은 파손율과 세척의 번그러움 및 높은 제조단가로 인하여 일회용으로는 적합하지 않아 거의 사용되지 않고 있다. 또한, 패스트푸드 및 편의점 자동판매기 뿐만아니라 일반 식생활에서도 뒷처리가 간편한 종이, 발포수지 등으로 제조된 일회용 용기의 사용이 증가하고 있는 추세이다.When using pottery or glass products as the food container as described above, it is difficult to secure storage and location, and due to the high breakage rate, the hassle of washing, and high manufacturing cost, it is not suitable for single use and is rarely used. In addition, the use of disposable containers made of paper, foamed resins, etc., which are easy to process after treatment, as well as fast food and convenience store vending machines are increasing.
이러한 일회용 용기로는 합성수지인 발포성 폴리스티렌을 일정두께로 성형하여 제조한 제품이 가장 널리 사용되고 있으며, 이외에 종이, 은박, 폴리에틸렌 또는 폴리프로필렌을 이용하여 일회용 용기를 제작하고 있다.As the disposable container, a product manufactured by molding a polystyrene foam to a predetermined thickness is most widely used. In addition, a disposable container is manufactured using paper, silver foil, polyethylene, or polypropylene.
이러한 일회용 용기류는 여러가지 우수한 장점으로 인해 사용량이 매년 증가하고 있으나, 사용량의 증가에 따라 환경오염이 가중되고, 사용후에는 각종 쓰레기와 함께 매립되어 쉽게 분해되지 않으며, 소각하는 경우 발생되는 환경호르몬과 유독물질로 인하여 환경 및 인체의 건강에 위협이 되고 있는 실정이다.These disposable containers are increasing year by year due to various advantages, but environmental pollution increases with increasing usage, and after use, they are buried together with various wastes and are not easily decomposed. Due to the substance is a situation that threatens the environment and human health.
최근 기존의 합성수지와 성질이 유사하면서 자연계의 미생물에 의하여 쉽게 분해되는 생분해성 용기가 개발되고 있다. 이중 자연계에 풍부하게 존재하고, 가격또한 저렴한 전분과 같은 생분해성 고분자에 관심이 고조되고 있으며, 이에 대한 연구도 활발히 진행되고 있다.Recently, biodegradable containers having similar properties to existing synthetic resins and easily degraded by natural microorganisms have been developed. Among them, there is abundant interest in biodegradable polymers such as starch, which are present in abundance in nature, and inexpensive, and research on this is being actively conducted.
특히 전분은 자연계에서 가장 손쉽고 저렴하게 얻을 수 있는 천연 고분자로서 주로 옥수수, 감자, 타피오카, 고구마, 밀, 쌀 등에서 추출되며, 포도당이α-1,4 글루코시드 결합으로 이루어진 아밀로오스와 포도당이 α-1,4 글루코시드 결합 및 α-1,6 글루코시드 결합을 하고 있는 아밀로펙틴으로 구성되어 있고, 일반적으로 아밀로오스가 0~28% 함유되어 있다.In particular, starch is a natural polymer that can be obtained easily and inexpensively in nature, and is mainly extracted from corn, potatoes, tapioca, sweet potatoes, wheat, and rice, and glucose and α-1,4 glucoside bonds are composed of amylose and glucose to α-1. It consists of amylopectin which has a 4,4 glucoside bond, and (alpha) -1,6 glucoside bond, and contains 0-28% of amylose generally.
이러한 전분은 출처 및 품종에 따라 이화학적 특성의 차이가 클 뿐만 아니라, 가공 및 저장하는 동안 여러 성분과 상호작용으로 인하여 물리적 성질이 크게 좌우되기 때문에 사용하고자 하는 용도에 따라 가교, 에테르, 에스테르, 산처리, 산화 및 그라프트시킨 변성전분을 사용하고 있다.These starches differ greatly in their physicochemical properties according to their source and variety, and because their physical properties are greatly influenced by their interaction with various components during processing and storage, crosslinking, ethers, esters, acids Modified starch treated, oxidized and grafted is used.
종래의 생분해성 용기들은 발포 폴리스티렌과 유사한 물성을 가지며 제조방법이 간단하지만 천연 소재 이외에 사용되는 첨가제 중 분해되지 않는 원료의 첨가로 인하여 토양에서 분해가 용이하지 않을 뿐더러 가격 또한 고가이므로 실용화에 어려움을 겪고 있다. Conventional biodegradable containers have similar properties to expanded polystyrene and have a simple manufacturing method, but are not easy to decompose in soil due to the addition of raw materials that are not decomposed among additives used in addition to natural materials, and have difficulty in practical use because they are expensive. have.
이러한 생분해성 소재는 미생물이나 자외선에 의하여 자연 상태에서 수 주일만에 분해되는 합성수지로, 가격이 기존의 합성수지보다 1.6 ~ 4배 비싸고 물성이 취약하지만 점차 대량생산이 가능하고 일반 합성수지의 거의 동일한 물성으로 개발되고 있다.These biodegradable materials are synthetic resins that are decomposed in a few weeks in a natural state by microorganisms or UV rays, and are 1.6 to 4 times more expensive than conventional synthetic resins and are weak in physical properties, but are able to be mass-produced and have almost the same properties as general synthetic resins. Is being developed.
대표적인 선행기술을 살펴보면, 대한민국 특허등록 제10-0548949호(생분해성 전분 용기 및 그 제조방법), 특허공개 제10-2006-0036075호(생분해성 전분을 주원료로 하는 용기조성물 및 그 제조방법), 특허공개 제10-2005-0007205호(천연 고분자를 이용한 생분해성 일회용 용기 제조방법 및 그 조성물), 특허공개 제10-2005-0023816호(옥수수를 활용한 생분해성 일회용 천연용기의 제조방법), 국내 특허등록 제10-0422413호(무공해 용기 및 그 제조방법) 등이 있다.Looking at the representative prior art, Republic of Korea Patent Registration No. 10-0548949 (biodegradable starch container and its manufacturing method), Patent Publication No. 10-2006-0036075 (container composition and biodegradable starch as a main raw material), Patent Publication No. 10-2005-0007205 (Method for producing biodegradable disposable container using natural polymer and its composition), Patent Publication No. 10-2005-0023816 (Method for producing biodegradable disposable natural container using corn), Korea Patent Registration No. 10-0422413 (no pollution container and its manufacturing method) and the like.
그러나, 이와 같은 생분해성 용기들은 생분해성 소재에 필러, 발포조제, 유연제, 가소제, 보강제, 보습제, 이형제 등 각종 화학적인 첨가물을 포함하고, 용기에 내수성을 부여하기 위하여 표면에 수지용액을 피복 건조하거나, 필름을 라미네이팅 하는 것을 추가로 하여 생분해가 용이하지 않아 환경오염을 방지하는데 적절하지 않는다.However, such biodegradable containers include various chemical additives such as fillers, foaming aids, softeners, plasticizers, reinforcing agents, moisturizers, and release agents in the biodegradable material, and the resin solution is coated or dried on the surface to impart water resistance to the container. In addition, it is not suitable to prevent environmental pollution because it is not easy to biodegrade by adding laminating film.
또한, 기존의 생분해성 용기는 내충격성과 내수성, 보존성, 살균성, 탈취성을 달성하기 위하여 추가적인 화학적 첨가물을 포함시킴으로써 오히려 미생물로부터 생분해를 막는 문제점을 가지고 있다.In addition, the existing biodegradable container has the problem of preventing biodegradation from microorganisms by including additional chemical additives to achieve impact resistance and water resistance, preservation, bactericidal, deodorant.
그리고, 이러한 생분해성 용기에 첨가제의 첨가를 제한하는 경우 생분해성 용기의 물성이 고르지 않아 강도가 약하게 되며, 보존성과 항균성이 떨어져 쉽게 부패 되는 추가적인 문제점이 발생하게 되므로, 화학적인 첨가제를 최소화하면서 전체적으로 친환경적인 소재를 개발하고, 이를 이용한 생분해성 용기의 연구가 지속적으로 필요한 시점이다. In addition, in the case of limiting the addition of additives to such biodegradable containers, the physical properties of the biodegradable containers are not uniform, so that the strength is weak, and additional problems of easy decay due to poor storage and antimicrobial properties occur, thereby minimizing chemical additives. It is time to develop new materials and research biodegradable containers using them.

여기서, 무화과나무(Ficus carica)는 뽕나무과 무화과나무속의 활엽관목으로서, 무화과 과실은 생과나 건과를 잼, 통조림, 비스킷, 페이스트 등의 식용으로 사용되었으며, 특히 무화과에는 암 치료 효과가 알려진 벤즈알데히드(benzaldehyde)와 소화를 돕는 단백질 분해효소인 휘신(ficin) 및 식이섬유를 함유하는 것으로 알려져 암, 변비, 치질, 간장병등의 약학조성물로서 사용되어 왔다{Oner and Akar, Lebensm-Wiss Technol. 26: 318-321 (1993); Kim et al., J. Kor. Agric. Chem. Soc. 35: 51-54 (1992); Ahmed et al., Planta Med. 54: 481 (1988); Shiraishi et al., J. Faculty Agric. Kyushu Univ. 41: 29-33 (1996)}.Here, the fig tree (Ficus carica) is a broad-leaved shrub of the mulberry family, and the fig fruit is used for foods such as jam, canned food, biscuits, pastes, etc. It has been used as a pharmaceutical composition for cancer, constipation, hemorrhoids, liver disease, etc. It is known to contain ficin and dietary fiber, which are protease enzymes for digestion. {Oner and Akar, Lebensm-Wiss Technol. 26: 318-321 (1993); Kim et al., J. Kor. Agric. Chem. Soc. 35: 51-54 (1992); Ahmed et al., Planta Med. 54: 481 (1988); Shiraishi et al., J. Faculty Agric. Kyushu Univ. 41: 29-33 (1996)}.
그러나, 무화과 나무의 피질내 수질에는 매우 많은 양의 유백색 유액이 유출되는데 이러한 유액에 대하여 약 13%의 고무질을 포함하는 것으로 알려져 왔으나, 이러한 유액의 고무질을 이용한 천연고무생산의 선행기술만 알려지고, 그 외의 활용도는 낮은 실정이다.However, in the cortex of the fig tree, a very large amount of milky milky milk is leaked, which has been known to contain about 13% of the rubbery oil, but only the prior art of natural rubber production using such rubbery milk is known. Other uses are low.
본 발명에서는 용기조성물에 무화과나무 유액을 포함하여 2차 용기조성물을 구성함에 있어 무화과나무 유액의 고무질이 본 발명의 생분해성 용기에 연성을 부여할 수 있어 생산되는 용기의 파단 또는 파손을 방지하도록 하면서, 사용시 내구력을 향상시키고자 하는 목적을 달성할 수 있다.In the present invention, in forming the secondary container composition including the fig tree emulsion in the container composition, the rubber of the fig tree emulsion can impart ductility to the biodegradable container of the present invention while preventing breakage or breakage of the produced container. In addition, it can achieve the purpose to improve the durability in use.
또한, 본 발명에서 무화과나무 유액을 사용하였으나, 이에 한정하지 않고 고무나무, 보리수나무 등의 고무질을 포함하는 나무의 유액을 사용 할 수 있음은 당업자에게 있어서는 자명한 것이므로, 더 자세한 설명은 생략하도록 한다.In addition, although the fig tree latex is used in the present invention, the present invention is not limited thereto, and it is obvious to those skilled in the art that a latex of a tree including rubber such as rubber tree and bodhi tree can be used, and thus a detailed description thereof will be omitted. .
본 발명에서 제조된 용기조성물 및 2차 용기조성물은 10∼180분 동안 혼련한다. 이후 50∼200℃ 로 미리 가열한 가열 가압 성형기에 용기조성물을 넣고 0.1∼10 Pa(N/m2)의 압력을 가하여 0.5∼10분 동안 성형하여 생분해성 용기를 제조한다. 성형된 천연용기를 인출하여 트리밍(trimming) 작업을 거친 후 경화 시켜 천연용기를 얻게 된다. The container composition and the secondary container composition prepared in the present invention are kneaded for 10 to 180 minutes. Thereafter, the container composition is placed in a pre-heated press molding machine heated to 50 to 200 ° C., and a pressure of 0.1 to 10 Pa (N / m 2) is applied to form a biodegradable container by molding for 0.5 to 10 minutes. The molded natural container is taken out, trimmed, and then cured to obtain a natural container.
이때, 생분해성 천연용기 제조시 성형기의 온도, 압력 및 성형시간은 서로 밀접한 관계를 가지고 있으나, 크기 및 용기의 용도에 따라 다양하게 조절 하여야 한다. 다만, 성형기의 내부온도가 50℃ 미만인 경우에는 성형시간이 증가하고, 성형기의 내부온도가 200℃를 초과하는 경우에는 용기조성물이 타거나 물성이 변형되어 용기의 성형성이 떨어질 수 있다.At this time, the temperature, pressure and molding time of the molding machine when manufacturing a biodegradable natural container has a close relationship with each other, but should be adjusted in various ways depending on the size and use of the container. However, when the internal temperature of the molding machine is less than 50 ℃, the molding time is increased, and when the internal temperature of the molding machine exceeds 200 ℃, the container composition is burned or the physical properties may be deformed to reduce the moldability of the container.
