또한, 최근에는 합성수지를 이용하여 일회용 접시나 그릇 등을 만들어서 배달음식점이나 행사장 등에서 많이 사용하고 있다.In recent years, disposable plates and bowls are made of synthetic resins and used in delivery restaurants and event venues.
상기 합성수지폐기물에 관한 문제점을 해결하기 위해서 최근에는 여러가지 방법으로 쉽게 분해되는 분해성 합성수지의 개발이 진행중이다.In order to solve the problems related to the synthetic resin waste, the development of a decomposable synthetic resin that is easily decomposed in various ways in recent years.
상기 분해성 합성수지는 생붕괴성, 광분해성, 생분해성, 복합분해 합성수지등으로 개발되고 있는데, 상기 생붕괴성 합성수지는 비분해성 범용플라스틱 수지에 전분 같은 생분해성 물질을 일정량 첨가하여 제조한 부분 분해성 합성수지이다. The degradable synthetic resin is being developed as biodegradable, photodegradable, biodegradable, and complex degradable synthetic resin. The biodegradable synthetic resin is a partially degradable synthetic resin prepared by adding a certain amount of biodegradable material such as starch to a non-degradable general purpose plastic resin. .
상기 광분해성 합성수지는 광산화 또는 케톤 광분해 등의 형태로 빛에 의해 분해되는 것을 말하고, 상기 생분해성 합성수지는 천연고분자 등을 이용하여 제품자체가 박테리아 조류, 곰팡이와 같은 자연계에 존재하는 미생물에 의해 물과 이산화탄소 또는 물과 메탄가스로 완전히 분해되는 합성수지이다.The photodegradable synthetic resin refers to being decomposed by light in the form of photooxidation or ketone photolysis, and the biodegradable synthetic resin uses natural polymers, etc., so that the product itself is separated from water by microorganisms existing in nature such as bacteria, algae, and fungi. It is a synthetic resin that is completely decomposed into carbon dioxide or water and methane gas.
상기 복합분해 합성수지는 합성수지 자체를 열분해, 화학분해, 광분해, 생분해 등의 1가지 이상의 분해 과정에 의해 물과 이산화탄소 또는 물과 메탄가스로 완전히 분해될 수 있도록 한 합성수지이다.The composite decomposition synthetic resin is a synthetic resin that can be completely decomposed into water and carbon dioxide or water and methane gas by one or more decomposition processes such as pyrolysis, chemical decomposition, photolysis, biodegradation itself.

The decomposition process by inanimate includes decomposition using active molecules such as hydrolysis, photosynthesis, ozone and radicals.
상기 생물학적 분해는 고분자 물질의 특성에 따라 좌우되며 무엇보다 박테리아와 효모가 작용하여 분해되며 최종 부산물로 물, 이산화탄소, 박테리아, 바이오매스 등이 남게 된다. The biodegradation depends on the characteristics of the polymer material, and above all, bacteria and yeast act to decompose and leave water, carbon dioxide, bacteria, biomass, etc. as final by-products.
기본적인 합성수지의 분해과정은 산화반응에 의한 분해이고, 개시반응을 거쳐 성장반응 단계에서 폴리머 중에 Hydroperoxide가 생성되며, 성장반응이 연쇄적으로 일어나서 폴리머 중에 라디칼이 생성되면 산화반응이 반복적으로 일어나게 된다.Basic decomposition of synthetic resin is decomposition by oxidation reaction, hydroperoxide is generated in polymer at the growth reaction stage through initiation reaction, and oxidation reaction occurs repeatedly when radical reaction is generated in the chain by growth reaction.

상기 폴리프로필렌은 열경화성 수지로 고분자 구조에 3차수소가 많이 있기 때문에 불안정하여 열화가 일어나기 쉬워서 상기 안정제를 사용한다. The polypropylene is a thermosetting resin, and since the tertiary hydrogen is high in the polymer structure, the polypropylene is unstable and easily deteriorated, so that the stabilizer is used.
상기 안정제는 부자유페놀(hindered phenols), 아인산염(phosphites) 또는 규산알미늄 중에 하나가 형성될 수 있다.The stabilizer may be one of hindered phenols, phosphites or aluminum silicate.
상기 전분은 천연고분자물질로 생분해성을 높이기 위해서 사용되는 것으로, 폴리프로필렌 100중량부당 8 ~ 15 중량부가 사용되는데 이러한 수치한정은 전분의 함량이 8 중량부보다 낮은 경우에는 생분해되는 시간이 지나치게 길어지고, 전분의 함량이 15중량부보다 높을 경우에는 강도가 떨어지게 된다.The starch is used to increase biodegradability as a natural polymer material, and 8 to 15 parts by weight per 100 parts by weight of polypropylene is used. When the starch content is lower than 8 parts by weight, biodegradation takes too long. If the starch content is higher than 15 parts by weight, the strength is lowered.
상기 전분에 의해서 생붕괴가 자연스럽게 일어나게 된다.The starch causes natural decay.
상기 안정제는 폴리프로필렌 100 중량부 당 0.05~0.3 중량부를 투여하는데, 이러한 수치한정은 안정제의 함량이 0.05 중량부보다 적을 경우에는 쉽게 열화되는 문제점이 있고, 0.3중량부 이상일 경우에는 쉽게 분해되지 않는다. The stabilizer is administered 0.05 ~ 0.3 parts by weight per 100 parts by weight of polypropylene, the numerical limit is a problem that is easily degraded when the content of the stabilizer is less than 0.05 parts by weight, it does not easily decompose when 0.3 parts by weight or more.
상기 보강제로는 실리카를 사용하는데, 쉽게 깨지거나 충격에 의해서 쉽게 파손되지 않도록 형성한다. Silica is used as the reinforcing agent, and is formed so as not to be easily broken or damaged by an impact.
상기 촉진제는 광분해성을 높이기 위해서 사용되는 것으로, 제1전이금속, 제2전이금속 또는 방향족케톤이 사용된다. The accelerator is used to increase photodegradability, and a first transition metal, a second transition metal or an aromatic ketone is used.
상기 촉진제는 폴리프로필렌 100중량부당 0.01~2 중량부가 사용되는데 이러한 수치한정은 촉진재의 함량이 0.01 중량부 이하일 경우에는 분해가 매우 천천히 진행되고, 2중량부 이상일 경우에는 쉽게 변색되고 보관성이 떨어지게 된다. The accelerator is used in an amount of 0.01 to 2 parts by weight per 100 parts by weight of polypropylene. When the content of the accelerator is 0.01 parts by weight or less, the decomposition proceeds very slowly. .
상기 촉진제에 의해서 광분해가 일어나게 된다.Photolysis is caused by the accelerator.
이하, 본 발명의 바람직한 실시예로 형성된 보온성과 분해성이 뛰어난 일회용품용 합성수지 조성물을 이용하여 일회용 용기를 생산하는 방법을 설명하면 다음과 같다.Hereinafter, a method of producing a disposable container using the synthetic resin composition for disposable products having excellent thermal insulation and degradability formed by the preferred embodiment of the present invention will be described.
먼저, 폴리프로필렌 81중량부에 전분 12.6중량부, 부자유페놀(hindered phenols) 0.2 중량부, 아인산염 2.5중량부, 실리카 2중량부, 촉진제 1.2중량부 및 진공유리구슬 0.5중량부를 혼합기에 투입하고 물 또는 희석알코올용액(1%이하)을 투여한 후에 고온, 고압에서 추출물을 얻어낸다.First, 12.6 parts by weight of starch, 0.2 parts by weight of hindered phenols, 2.5 parts by weight of phosphite, 2 parts by weight of silica, 1.2 parts by weight of accelerator, and 0.5 parts by weight of vacuum glass bead were added to the mixer. Alternatively, extracts are obtained at high temperature and high pressure after administration of a dilute alcohol solution (1% or less).
