Description
본 발명은 이산화규소를 함유한 불연성 바인더 조성물을 이용하여 폐플라스틱, 폐스티로폼 및 폐유리를 재활용하는 방법 및 상기 방법으로 재활용 처리된 친환경적이며 불연성을 갖는 건축용 자재에 관한 것이다. The present invention relates to a method for recycling waste plastic, waste styrofoam, and waste glass by using a non-combustible binder composition containing silicon dioxide, and to an environmentally friendly and non-flammable building material recycled by the method.
폐플라스틱, 폐비닐, 폐스티로폼의 자원순환 및 재활용 방법으로 고체원료, 재생원료, 유화원료(油化), 건축자재 제조 등의 다양한 기술들이 사용되고 있으나, 재활용률, 친환경성, 효율성, 상품성 및 선별의 어려운 문제로 재활용률은 10%대에 미치지 못하고 있는 실정이다. Various technologies such as solid raw materials, recycled raw materials, emulsified raw materials, and construction materials manufacturing are used as a resource recycling and recycling method for waste plastic, waste vinyl, and waste styrofoam, but the recycling rate, eco-friendliness, efficiency, marketability and selection Due to a difficult problem, the recycling rate is less than 10%.
폐비닐, 폐플라스틱 재활용 기술로는 고체원료 제조기술, 즉 폐비닐 등을 잘게 분쇄한 다음, 목재 등과 섞은 후 그 혼합물을 작은 알갱이 형태로 압축하여, 연료용 펠릿(pellet)으로 만드는 기술로 이렇게 제조된 연료용 펠릿은 난방연료나 공장 또는 화력발전소용 연료로 사용된다. 그러나 이러한 방법은 연료로 사용하고 소각 시, 여러 공해물질과 1급 발암물질인 다이옥신이 발생하여 환경과 민원 문제가 발생되고 있다.Waste vinyl and waste plastic recycling technology is a technology for manufacturing solid raw materials, that is, waste vinyl, etc., finely pulverized, mixed with wood, etc., and then compressed into small grains to form pellets for fuel. The pellets for fuel are used as heating fuel or fuel for factories or thermal power plants. However, these methods are used as fuel and when incinerated, various pollutants and dioxin, which is a first-class carcinogen, are generated, causing environmental and civil complaints.
또한, 폐플라스틱, 폐스티로폼을 재활용하는 기술로는 폐플라스틱을 원료와 색상에 따라 각각 분류하여, 분쇄 및 세척 후 가열하여 펠릿(pellet)으로 만들어 재생 플라스틱 원료로 사용하는 기술이 있는데, 이러한 기술은 원료별, 색상별 선별 분류 시 비용이 많이 발생하고, 재생제품 품질을 위해 A급 자재를 선별 분류해야 하므로 재생률이 낮으며, 재생된 원료는 플라스틱 원료 신제품에 비해 가격경쟁력이 크게 좋지 않아 효율성이 떨어지는 문제점이 있다.In addition, as a technology for recycling waste plastics and waste styrofoam, there is a technology that classifies waste plastics according to their raw materials and colors, pulverizes and cleans them, and then heats them into pellets and uses them as recycled plastic raw materials. In the case of sorting by raw material and color, the cost is high, and the recycling rate is low because Class A materials must be sorted for quality of recycled products, and the recycled raw materials are less efficient because their price competitiveness is significantly lower than that of new plastic raw materials. There is a problem.
또한, 폐비닐, 폐플라스틱, 폐스티로폼 재활용 기술로 유화(油化)기술이 사용되고 있는데 400℃ 이상의 고온에서 이를 분해해 경유와 같은 산업용 연료나, 석유화학 원료로 만들어 사용하는 기술이다. 그러나 이러한 기술은 유화(油化)설비 비용이 높고, 제조 과정에서 에너지의 소모가 많아 제조비용이 많이 발생되며, 제조된 연료를 정제해야 하는데 이러한 과정에서 비용대비 효율성이 떨어지는 문제점이 발생한다.In addition, an emulsification technology is used as a recycling technology for waste vinyl, waste plastic, and waste styrofoam. It is a technology that decomposes it at a high temperature of 400°C or higher to produce industrial fuels such as diesel or petrochemical raw materials. However, such a technology has a high cost of emulsification equipment, high energy consumption in the manufacturing process, resulting in a high manufacturing cost, and a problem of inferior cost-efficiency in this process.
또 다른 폐비닐, 폐플라스틱 재활용 기술은 폐비닐, 폐플라스틱을 가열 성형하거나, 가열 후 다른 금속재료 등과 결합시켜, 건축자재를 제조하여 사용하거나, 지붕 패널, 건물 벽체 등 다양한 건축자재를 응용 제조하는 기술이 있으나, 이러한 기술은 제조된 건축자재가 화재에 취약하여, 화재 시 유독가스 발생과 화재를 촉매 시키는 역할을 할 수 있는 문제점이 발생하고 있다.Another technology for recycling waste vinyl and waste plastic is to heat-form waste vinyl and waste plastic, or combine it with other metal materials after heating to manufacture and use building materials, or to apply and manufacture various building materials such as roof panels and building walls. Although there is a technology, this technology has a problem in that the manufactured building materials are vulnerable to fire, and thus can play a role of catalyzing the generation of toxic gases and fire in the event of a fire.
따라서 이러한 문제점을 해결하면서 동시에 재활용률을 향상시키기 위한 새로운 기술의 개발이 필요한 실정이다. Therefore, it is necessary to develop a new technology to solve these problems and at the same time improve the recycling rate.
따라서 본 발명의 목적은 폐비닐, 폐플라스틱, 폐유리, 폐목재 등과 같은 폐건축자재의 재활용률을 향상시킬 수 있고 친환경적이며 불연성이 우수한, 새로운 폐건축자재의 재활용 방법을 제공하는 것이다.Accordingly, an object of the present invention is to provide a new recycling method of waste building materials, which can improve the recycling rate of waste building materials such as waste vinyl, waste plastic, waste glass, waste wood, etc., and is eco-friendly and excellent in non-combustibility.

본 발명은 폐건축자재를 이용하여 친환경적이며 불연성을 갖는 건축용자재로 재활용하는 새로운 방법을 제공함에 특징이 있다.The present invention is characterized in providing a new method of recycling as an eco-friendly and non-flammable building material using waste building materials.
구체적으로 본 발명에 따른 폐건축자재의 재활용 방법은 이산화규소를 함유한 불연성 바인더 조성물을 이용함에 특징이 있는데, 구체적으로 본 발명의 불연성 바인더 조성물은 물, 산화규소(silicon dioxide), 산화나트륨(sodium oxide), 산화알루미늄(aluminum oxide), 산화칼륨(potassium monoxide), 산화칼슘(calcium oxide) 및 미량물질을 유효성분으로 포함하며, 이때 상기 불연성 바인더 조성물 총 중량기준, 물은 60~80%, 산화규소는 10~20%, 산화나트륨은 2~10%, 산화알루미늄은 1~5%, 산화칼륨은 0.1~1%, 산화칼슘은 0.1~1% 및 미량물질은 2%로 포함되어 있다.Specifically, the method for recycling waste construction materials according to the present invention is characterized by using a non-combustible binder composition containing silicon dioxide.

또한 상기 불연성 바인더 조성물은 바인더의 강성을 완화시켜 주고 플렉서블한 성질을 구현해주며 발수성을 보완하기 위한 용도로 천연라텍스를 더 포함할 수 있으며, 바람직하게 상기 천연라텍스는 천연라텍스 원액을 10~50%의 양으로 첨가할 수 있다.In addition, the non-combustible binder composition may further include a natural latex for a purpose to relieve the stiffness of the binder, implement a flexible property, and supplement water repellency.

여기서 상기 천연라텍스 원액은 상기 원액을 10% 미만의 양으로 혼합하게 되면 성형성이 저하되는 문제점이 있고, 50% 이상이 초과하여 혼합하게 되면 상대적으로 불연성이 감소되는 단점을 가진다. 따라서 천연라텍스 원액은 10~50%의 양으로 첨가하는 것이 바람직하며, 더욱 바람직하게는 10~30%의 양으로 첨가할 수 있다.Here, the natural latex undiluted solution has a problem in that when the undiluted solution is mixed in an amount of less than 10%, the moldability is deteriorated, and when it is mixed in an amount exceeding 50%, the nonflammability is relatively reduced.
