Description
본 발명은 생분해성 플라스틱 조성물 및 이에 의해 제조된 생분해성 플라스틱 제품에 관한 것으로, 보다 상세하게는 고분자 수지에 전분과 항균 및 항곰팡이 특성이 있는 첨가제를 투입하여 제조함으로써, 미생물 또는 효모 등에 의하여 생분해되면서도 항균 및 항곰팡이 특성이 있는 생분해성 플라스틱 조성물 및 이에 의해 제조된 생분해성 플라스틱 제품에 관한 것이다.The present invention relates to a biodegradable plastic composition and a biodegradable plastic product manufactured therefrom. More specifically, it is manufactured by adding starch and additives with antibacterial and antifungal properties to a polymer resin, so that it is biodegradable by microorganisms or yeast, etc. It relates to a biodegradable plastic composition with antibacterial and antifungal properties and a biodegradable plastic product manufactured thereby.
일반적으로 플라스틱은 가볍고 튼튼하며, 원하는 색깔을 마음대로 낼 수 있으며, 어떠한 형태로든 자유자재로 만들 수 있다는 장점이 있다. 이러한 뛰어난 가공성 때문에 플라스틱은 가전제품, 생활용품, 가구, 건축자재, 전기용품 등의 흔히 보이는 딱딱한 합성수지에서부터 비닐, 합성섬유에 이르기까지 여러 방면에서 사용되고 있다. In general, plastic has the advantage of being light and strong, being able to produce any desired color, and being made into any shape. Because of this excellent processability, plastics are used in many fields, from hard synthetic resins commonly found in home appliances, household goods, furniture, building materials, and electrical appliances to vinyl and synthetic fibers.
그러나, 이러한 플라스틱 제품들은 자연계에서 거의 분해되지 않고 반영구적으로 존재하기 때문에 다수의 환경 문제를 야기할 뿐만 아니라, 최근에는 스티렌 다이버, 스티렌 트라이머 등과 같이 내분비계를 교란시키는 환경 호르몬을 방출하는 것으로 밝혀져 사회적으로 큰 문제를 야기하고 있다. However, since these plastic products are rarely decomposed in the natural world and exist semi-permanently, they not only cause a number of environmental problems, but have recently been found to emit environmental hormones such as styrene diver and styrene trimer that disrupt the endocrine system, raising social concerns. is causing a big problem.
기존에는 폐 플라스틱을 매립, 소각, 재활용 등의 방법을 통해 처리하고 있었으나, 매립시에는 자꾸 늘 어나는 쓰레기로 인하여 매립공간이 부족해지고, 매립 후에는 분해되기 어려운 플라스틱 폐기물로 인하여 지반이 안정되지 않아 매립지의 이용에 많은 문제점이 있다. Previously, waste plastic was treated through methods such as landfilling, incineration, and recycling, but landfill space became insufficient due to the ever-increasing amount of waste during landfilling, and the ground became unstable due to plastic waste that was difficult to decompose after landfilling. There are many problems with the use of landfills.
또한, 폐 플라스틱을 소각하는 경우에는 비산 분진 발생과 더불어 다이옥신, 일산화탄소 등의 유해가스가 대량 발생하여 대기오염 및 인체에 심각한 해를 끼치는 원인이 되고 있으며, 재활용하는 경우에는 플라스틱 폐기물의 분리수거가 어렵고, 수거 후에도 혼입된 불순물 제거에 과다한 비용이 소요되어 경제적 측면에서도 문제가 되고 있다. In addition, when incinerating waste plastic, large amounts of harmful gases such as dioxin and carbon monoxide are generated along with the generation of fugitive dust, which causes air pollution and serious harm to the human body. When recycling, it is difficult to separate and collect plastic waste. , even after collection, excessive costs are required to remove mixed impurities, which is also a problem from an economic perspective.
본 발명의 과제는 고분자 수지에 전분과 항균 및 항곰팡이 특성이 있는 첨가제를 투입하여 제조함으로써, 미생물 또는 효모 등에 의하여 생분해되면서도 항균 및 항곰팡이 특성이 있는 생분해성 플라스틱 조성물 및 이에 의해 제조된 생분해성 플라스틱 제품을 제공함에 있다. The object of the present invention is to produce a biodegradable plastic composition that is biodegradable by microorganisms or yeast and has antibacterial and antifungal properties by adding starch and additives with antibacterial and antifungal properties to a polymer resin, and the biodegradable plastic manufactured thereby. In providing products.
상기의 과제를 달성하기 위한 본 발명에 따른 생분해성 플라스틱 조성물은 미생물에 의해 생분해되는 것으로, 전분과, 항균 및 항곰팡이 성분을 포함하는 첨가제, 및 고분자 수지를 포함할 수 있다. The biodegradable plastic composition according to the present invention for achieving the above problems is biodegradable by microorganisms and may include starch, an additive containing antibacterial and antifungal ingredients, and a polymer resin.
또한, 빛에 의해 광분해되는 광분해제를 더 포함할 수 있다. In addition, a photodecomposition agent that is photodegraded by light may be further included.
또한, 상기 첨가제는 산화아연 나노입자, 제올라이트, 소성 패각분말, 및 방담제를 포함할 수 있다. Additionally, the additive may include zinc oxide nanoparticles, zeolite, calcined shell powder, and anti-fogging agents.

본 발명에 따른 생분해성 플라스틱 조성물은 상기 생분해성 플라스틱 조성물을 이용하여 제조될 수 있다. The biodegradable plastic composition according to the present invention can be manufactured using the biodegradable plastic composition.
본 발명에 따른 생분해성 플라스틱 조성물은 고분자 수지에 전분을 첨가하여 제조함으로써, 미생물 또는 효모 등에 의하여 생분해되는 생분해성 플라스틱 제품을 제조할 수 있게 된다. 이에 따라, 플라스틱 폐기물의 매립, 소각 등에 따른 토양, 대기, 해양 오염의 문제점을 최소화할 수 있다. The biodegradable plastic composition according to the present invention is manufactured by adding starch to a polymer resin, making it possible to manufacture a biodegradable plastic product that is biodegraded by microorganisms or yeast. Accordingly, problems with soil, air, and ocean pollution caused by landfilling and incineration of plastic waste can be minimized.
또한, 생분해성 플라스틱 조성물에 항균 특성 및 항곰팡이 특성을 부여하기 위한 첨가제를 포함함으로써 생분해성 플라스틱 조성물을 이용하여 음식물의 포장 용기를 제조하는 경우, 음식물이 빠르게 상하는 것을 방지하는 동시에 용기를 재사용 할 수 있다는 이점이 있다. In addition, by including additives to impart antibacterial and anti-fungal properties to the biodegradable plastic composition, when manufacturing food packaging containers using the biodegradable plastic composition, the food can be prevented from spoiling quickly and the container can be reused. There is an advantage to having it.
또한, 생분해성 플라스틱 조성물에 광분해제를 첨가해 줌으로써 제품이 분해되는 속도를 향상시킬 수 있게 된다. Additionally, by adding a photodegrader to the biodegradable plastic composition, the speed at which the product decomposes can be improved.
이하 첨부된 도면을 참조하여, 바람직한 실시예에 따른 생분해성 플라스틱 조성물 및 이에 의해 제조된 생분해성 플라스틱 제품에 대해 상세히 설명하면 다음과 같다. 여기서, 동일한 구성에 대해서는 동일부호를 사용하며, 반복되는 설명, 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 및 구성에 대한 상세한 설명은 생략한다. 발명의 실시형태는 당업계에서 평균적인 지식을 가진 자에게 본 발명을 보다 완전하게 설명하기 위해서 제공되는 것이다. 따라서, 도면에서의 요소들의 형상 및 크기 등은 보다 명확한 설명을 위해 과장될 수 있다. Hereinafter, with reference to the attached drawings, the biodegradable plastic composition according to a preferred embodiment and the biodegradable plastic product manufactured thereby will be described in detail as follows. Here, the same symbols are used for the same components, and repetitive descriptions and detailed descriptions of known functions and configurations that may unnecessarily obscure the gist of the invention are omitted. Embodiments of the invention are provided to more completely explain the invention to those skilled in the art. Accordingly, the shapes and sizes of elements in the drawings may be exaggerated for clearer explanation.
본 발명은 생분해성 플라스틱 조성물 및 이에 의해 제조된 생분해성 플라스틱 제품에 괸한 것으로, 생분해성 플라스틱 조성물은 전분과, 항균 및 항곰팡이 성분을 포함하는 첨가제, 및 고분자 수지를 포함할 수 있다. 그리고, 생분해성 플라스틱 제품은 생분해성 플라스틱 조성물을 이용하여 제조된 것으로서, 음료 용기, 포장 용기, 포장용 비닐 등을 포함할 수 있다. The present invention relates to a biodegradable plastic composition and a biodegradable plastic product manufactured therefrom. The biodegradable plastic composition may include starch, an additive containing antibacterial and antifungal ingredients, and a polymer resin. In addition, biodegradable plastic products are manufactured using biodegradable plastic compositions and may include beverage containers, packaging containers, packaging vinyl, etc.
본 발명에 따른 생분해성 플라스틱 조성물은 고분자 수지에 전분을 함유시킴으로써 미생물 또는 효모 등에 의해 생분해되는 플라스틱 조성물을 제조할 수 있다. 여기서, 전분은 옥수수에서 추출될 수 있으며, 고분자 수지는 폴리에틸렌테레프탈레이트(polyethyleneterephthalate)를 포함할 수 있다. 폴리에틸렌테레프탈레이트의 경우 투명하고 가벼워 각종 음식물의 포장 용기로 사용하기 적합한 이점이 있다. 그러나, 재사용할 경우에는 박테리아가 쉽게 번식하기 때문에 한번 이용한 이후에는 재사용할 수 없거나, 오픈한 이후에는 빠르게 음식물을 섭취해야만 하는 단점이 있다. The biodegradable plastic composition according to the present invention can be manufactured by containing starch in a polymer resin, which is biodegradable by microorganisms or yeast. Here, starch may be extracted from corn, and the polymer resin may include polyethyleneterephthalate. Polyethylene terephthalate has the advantage of being transparent and light, making it suitable for use as packaging containers for various foods. However, when reusing it, there is a disadvantage that it cannot be reused after one use because bacteria multiply easily, or that food must be consumed quickly after opening.
이에 본 발명에 따른 생분해성 플라스틱 조성물은 항균 특성 및 항곰팡이 특성을 부여하기 위한 첨가제를 포함할 수 있다. 예를 들어, 첨가제는 산화아연 나노입자, 제올라이트, 소성 패각분말, 및 방담제를 포함할 수 있으며, 이들을 배합 사용함으로써 항균 특성 및 항곰팡이 특성을 모두 확보할 수 있다. Accordingly, the biodegradable plastic composition according to the present invention may include additives to provide antibacterial and antifungal properties. For example, additives may include zinc oxide nanoparticles, zeolite, calcined shell powder, and anti-fogging agents, and by using them in combination, both antibacterial and antifungal properties can be secured.
그리고, 산화아연 나노입자, 제올라이트, 소성 패각분말, 및 방담제는 실리콘 오일을 이용하여 표면 개질될 수 있다. 이를 통해 입자 간 뭉침 현상이 방지되어 첨가제를 소량 첨가하여도 우수한 항균성 및 항곰팡이성을 확보할 수 있으면서도 폴리에틸렌테레프탈레이트와 잘 혼합될 수 있다. Additionally, zinc oxide nanoparticles, zeolite, calcined shell powder, and anti-fog agents can be surface modified using silicone oil. This prevents agglomeration between particles, ensuring excellent antibacterial and anti-fungal properties even with a small amount of additives, and can be mixed well with polyethylene terephthalate.
방담제는 생분해성 플라스틱 조성물의 표면에 얇은 방담막을 형성시켜 물방울이 맺히는 것을 방지하기 위한 것으로, 이를 첨가함으로써 곰팡이가 번식하기 쉬운 습한 환경을 개선할 수 있다. 이를 통해, 생분해성 플라스틱 조성물을 이용하여 음식물을 포장하기 위한 생분해성 플라스틱 제품을 제조하는 경우, 내용물의 신선도를 보다 장기간 유지할 수 있게 된다. 예를 들어, 방담제는 솔비탄 지방산 에스테르, 글리세린 지방산 에스테르 및 폴리글리세린 지방산 에스테르 등으로 이루어진 군에서 선택되는 하나 또는 둘 이상으로 제공될 수 있다. Anti-fog agent is used to prevent water droplets from forming by forming a thin anti-fog film on the surface of a biodegradable plastic composition. By adding it, a humid environment in which mold can easily grow can be improved. Through this, when manufacturing biodegradable plastic products for packaging food using a biodegradable plastic composition, the freshness of the contents can be maintained for a longer period of time. For example, the anti-fogging agent may be provided as one or two or more selected from the group consisting of sorbitan fatty acid ester, glycerin fatty acid ester, and polyglycerin fatty acid ester.
한편, 생분해성 플라스틱 조성물은 빛에 의해 광분해되는 광분해제를 더 포함할 수 있다. 광분해제는 고분자 사슬을 끊어 분해시키기 위해 첨가되는 것으로서, 고분자의 산화를 촉진시키기 위해 철(Fe), 아연(Zn), 티타늄(Ti), 망간(Mn) 중 적어도 하나를 포함할 수 있다. 이러한 광분해제는 금속 자체로 조성물에 첨가될 수도 있으나, 유기 화합물과 결합된 유기 컴플렉스의 형태로 첨가될 수도 있다.Meanwhile, the biodegradable plastic composition may further include a photodegradation agent that is photodegraded by light. The photodecomposer is added to break the polymer chain and decompose it, and may contain at least one of iron (Fe), zinc (Zn), titanium (Ti), and manganese (Mn) to promote oxidation of the polymer. These photolytic agents may be added to the composition as the metal itself, or may be added in the form of an organic complex combined with an organic compound.
이와 같이, 생분해성 플라스틱 조성물에 광분해제가 포함됨에 따라 생분해성 플라스틱 조성물을 이용하여 제품을 제조하였을 때, 제품이 분해되는 속도를 향상시킬 수 있게 된다. In this way, as the photodegrader is included in the biodegradable plastic composition, the decomposition speed of the product can be improved when the product is manufactured using the biodegradable plastic composition.
전술한 바와 같이, 생분해성 플라스틱 조성물은 고분자 수지에 전분을 첨가하여 제조함으로써, 미생물 또는 효모 등에 의하여 생분해되는 생분해성 플라스틱 제품을 제조할 수 있게 된다. 이에 따라, 플라스틱 폐기물의 매립, 소각 등에 따른 토양, 대기, 해양 오염의 문제점을 최소화할 수 있다. As described above, a biodegradable plastic composition is manufactured by adding starch to a polymer resin, making it possible to manufacture a biodegradable plastic product that biodegrades by microorganisms or yeast. Accordingly, problems with soil, air, and ocean pollution caused by landfilling and incineration of plastic waste can be minimized.
또한, 생분해성 플라스틱 조성물에 항균 특성 및 항곰팡이 특성을 부여하기 위한 첨가제를 포함함으로써 생분해성 플라스틱 조성물을 이용하여 음식물의 포장 용기를 제조하는 경우, 음식물이 빠르게 상하는 것을 방지하는 동시에 용기를 재사용 할 수 있다는 이점이 있다. In addition, by including additives to impart antibacterial and anti-fungal properties to the biodegradable plastic composition, when manufacturing food packaging containers using the biodegradable plastic composition, the food can be prevented from spoiling quickly and the container can be reused. There is an advantage to having it.
또한, 생분해성 플라스틱 조성물에 광분해제를 첨가해 줌으로써 제품이 분해되는 속도를 향상시킬 수 있게 된다. Additionally, by adding a photodegrader to the biodegradable plastic composition, the speed at which the product decomposes can be improved.
