Description
본 발명은 친환경포장재(EPL, Eco Plastic) 제조용 규산염 산화촉매제 조성물 및 그 제조방법에 관한 것으로, 보다 상세하게는 인체에 전혀 무해하고, 토양을 오염시키기 않으며, 작물의 성장에 악영향을 미치지 않으며, 기존 생산 설비의 보완으로 생산이 가능하며, 고분자의 폴리올레핀계 플라스틱 수지의 분자량(Mw) 수치를 감소시켜 미생물에 의해 완전히 분해가 되며, 실용성 및 시장성이 우수한 친환경포장재 제조용 규산염 산화촉매제 조성물 및 그 제조방법에 관한 것이다.The present invention relates to a silicate oxidation catalyst composition for manufacturing eco-friendly packaging material (EPL, Eco Plastic) and a method of manufacturing the same, more specifically, it is completely harmless to the human body, does not pollute the soil, does not adversely affect the growth of crops, It is possible to produce by supplementing the production equipment, reduce the molecular weight (Mw) value of the polymer polyolefin-based plastic resin is completely decomposed by microorganisms, silicate oxidation catalyst composition for manufacturing eco-friendly packaging material with excellent practicality and marketability and its manufacturing method It is about.
일반적으로, 수지 조성물은 각종 전기 제품에 사용되고 있다. 그러나 수지 조성물은 폐기 처분 시 연소하면 고열로 인해 연소로를 파손시키며, 또한 다이옥신 등 환경호르몬과 유독 가스를 발생하며, 자연 상태(흙속)에 매립하더라도 반영구적으로(50~100년간) 생분해(미생물 분해)가 되지 않기 때문에 폐기처분이 용이하지 않고, 환경문제를 야기할 수 있다는 문제가 있다.Generally, resin compositions are used for various electrical products. However, when the resin composition is burned at the time of disposal, it breaks the combustion furnace due to high heat, and also generates environmental hormones and toxic gases such as dioxin, and biodegradation (50 to 100 years) biodegradation (microbial decomposition) even when it is buried in nature (dirt). ), There is a problem that it is not easy to dispose of and may cause environmental problems.
2001년 4월부터 "사용 완료 전기 제품 리사이클법"이 시행되어, 현재, TV 등의 대형 전기 제품의 회수가 시작되고 있지만, 회수된 대형 전기 제품의 대부분은 리사이클 되는 일이 없고, 법적 규제도 없기 때문에 불연 쓰레기로서 폐기처분되고 있다. 한편, 소형 전기 제품의 경우에는 일반적으로 대형 전기 제품에 비하여 판매수가 많기 때문에, 전체적으로 다량의 불연 먼지가 발생한다. 따라서, 대형, 소형에 관계없이 전기 제품의 폐기처분은 현재 심각한 사회 문제가 되고 있다.The "Used Electric Products Recycling Act" has been in effect since April 2001. At present, the recovery of large-scale electrical appliances such as TVs has begun, but most of the large-scale electrical appliances recovered have not been recycled and there are no legal regulations. Therefore, it is disposed of as non-combustible waste. On the other hand, in the case of small electrical appliances, since the number of sales is generally larger than that of large electrical appliances, a large amount of non-combustible dust is generated as a whole. Therefore, disposal of electrical products, whether large or small, is now a serious social problem.
최근, 이러한 사회 문제를 해결하는 대책으로서 생분해성 수지가 주목받고 있다. 상기 생분해성 수지란 사용 후 저분자 화합물을 자연계에서 미생물이 섭취하여, 최종적으로는 물과 이산화탄소로 분해되는 플라스틱을 말한다.(생분해성 플라스틱 연구회, ISO/TC-207/SC3). 이러한 생분해성 수지는 지금까지 농림수산용 자재(필름, 식재포트, 낚시 실, 어망), 토목공사용 자재(보수 시트, 식물 네트 등), 포장·용기 분야(흙, 식품 등이 부착되어 리사이클이 어려운 물건) 등 주로 일회용 제품에 대하여 실용화가 진행되어 오고 있다.In recent years, biodegradable resins have attracted attention as a countermeasure for solving such social problems. The biodegradable resin refers to a plastic that is ingested by a microorganism in nature after use, and finally decomposed into water and carbon dioxide (Biodegradable Plastics Research Group, ISO / TC-207 / SC3). Such biodegradable resins have been difficult to recycle since they are attached to materials for agriculture, forestry and fisheries (film, food pot, fishing thread, fishing net), materials for civil engineering (repair sheet, plant net, etc.), packaging and container fields (soil, food, etc.). Commercialization of the disposable products, such as articles) has been in progress.
이러한 문제점을 해결하기 위해 안출된 것이 한국 등록특허 제10-1032625호이다.Korean Patent No. 10-1032625 has been devised to solve this problem.

그러나, 선행특허는 분해제로 지방족 카르복실산(aliphatic carboxylic acid), 케톤(ketone), 산화철(FeO) 등을 2종 이상 혼합하여 사용하여 강제 분해시키며, 이로 인해 토양오염을 유발하고, 작물의 성장에 악영향을 미치기에, 친환경 포장재로는 한계가 있다는 문제가 있으며, 분해제 투입으로 인해 제조원가가 상승하여 실용성 및 시장성이 저하된다는 문제가 있다.However, the prior patent uses a mixture of two or more aliphatic carboxylic acid (ketone), iron oxide (FeO), etc. as a decomposition agent forcibly decomposed, resulting in soil pollution, crop growth There is a problem that there is a limit to the eco-friendly packaging material because it adversely affects, there is a problem that the practical cost and marketability is lowered due to the increase in manufacturing cost due to the decomposition agent.
따라서 본 발명의 목적은 상기와 같은 문제를 해결하기 위해 안출된 것으로, 인체에 전혀 무해하고, 토양을 오염시키기 않으며, 작물의 성장에 악영향을 미치지 않으며, 기존 생산 설비의 보완으로 생산이 가능하며, 고분자의 폴리올레핀계 플라스틱 수지의 분자량(Mw)의 수치를 5,000(Mw) 이하로 감소시켜 미생물에 의해 완전히 분해가 되며, 실용성 및 시장성이 우수한 친환경포장재 제조용 규산염 산화촉매제 조성물 및 그 제조방법을 제공하고자 하는 것이다.Therefore, the object of the present invention was devised to solve the above problems, it is harmless to the human body, does not pollute the soil, does not adversely affect the growth of the crop, can be produced as a supplement of the existing production equipment, To reduce the value of the molecular weight (Mw) of the polyolefin-based plastic resin of the polymer to 5,000 (Mw) or less is completely decomposed by microorganisms, to provide a silicate oxidation catalyst composition for producing eco-friendly packaging material excellent in practicality and marketability, and to provide a method will be.
