폐페인트 발포 고체연료의 제조방법{Manufacturing Method of Solid Fuel foamed Waste Paint}Manufacturing Method of Solid Fuel foamed Waste Paint}

본 발명은 폐페인트 발포 고체연료 및 그 제조방법에 관한 것으로, 더욱 상세하게는 수거해온 폐페인트를 반고상 또는 고상으로 발포 성형하여 발전소, 시멘트소성로 등에 사용되는 열원으로 사용하기 위한 고상화 제조기술에 관한 것이다.The present invention relates to a waste paint foamed solid fuel and a manufacturing method thereof, and more particularly, to a solidification manufacturing technology for use as a heat source used in power plants, cement kilns, etc. by foaming the collected waste paint into semi-solid or solid state. About.

폐페인트는 고상, 반고상, 액상 등 3종류로 구분되고 대부분 액상이 주종을 이루고 있으며, 그 종류로는 폐페인트와 폐락카가 있다. Waste paints are divided into three types: solid, semi-solid, and liquid, and most of them are liquid, and the types include waste paint and waste lacquer.

지정폐기물인 폐페인트는 현재 대부분 소각로에 수거해온 그대로 소각을 하여 처리하는 방식이다. 일반적으로 폐페인트를 소각하게 되면 폐페인트 내부로 산소공급이 원활하지 않아 연소가 느리고 검은 연기와 유독가스가 발생하게 되어 이를 제거 또는 저감하는 시설을 해야 한다. 이와 같은 문제 때문에 폐페인트는 발열 열량을 많아 주요한 대체 에너지원으로 사용할 수 있는 충분한 가치가 있는 소재인데도 그대로 소각하는 것이 일반적이며, 이에 폐페인트의 효과적인 재활용을 위한 연구가 필요한 실정이다. Waste paint, which is a designated waste, is currently incinerated as it has been collected in most incinerators. In general, when waste paint is incinerated, the supply of oxygen to the inside of the waste paint is not smooth, so the combustion is slow and black smoke and toxic gases are generated, so a facility to remove or reduce them is required. Because of this problem, waste paint is a material that is valuable enough to be used as a major alternative energy source due to its high calorific value, but it is common to incinerate it as it is, and thus, research for effective recycling of waste paint is required.

폐페인트 재활용 연구의 한 분야로 폐페인트를 연료화하는 기술이 개발되어 제안되고 있으며, 대표적으로 대한민국특허등록 제10-0503347호(폐페인트와 분진, 오니를 이용한 고체 연료 제조방법), 대한민국특허등록 제10-0560700호(폐페인트를 이용한 고체 연료의 제조방법), 대한민국특허등록 제10-0661875호(폐페인트를 이용한 가연성 고체연료), 대한민국특허등록 제10-0767757호(폐페인트를 이용한 재생연료유 및 이의 제조방법) 등이 있다.As a field of waste paint recycling research, a technology for converting waste paint into fuel has been developed and proposed. Representatively, Korean Patent Registration No. 10-0503347 (Method of manufacturing solid fuel using waste paint, dust, and sludge), Korean patent registration has been made. 10-0560700 (Method of manufacturing solid fuel using waste paint), Korean Patent Registration No. 10-0661875 (Combustible solid fuel using waste paint), Korean Patent Registration No. 10-0767757 (Regenerated fuel oil using waste paint) And a manufacturing method thereof).

본 발명은 폐페인트의 고체연료로 재활용하기 위해 개발된 것으로서, 폐페인트를 발포하여 내부에 기공이 형성된 반고상 또는 고상의 발포폼으로 성형시킴으로써 발전소, 시멘트소성로 등의 열원으로 유리하게 사용할 수 있는 폐페인트 발포 고체연료와 이의 바람직한 제조방법을 제공하는데 기술적 과제가 있다.The present invention was developed to recycle waste paint as a solid fuel, and by foaming the waste paint and molding it into a semi-solid or solid foamed foam with pores inside, it can be advantageously used as a heat source for power plants and cement kilns. There is a technical problem in providing a paint foamed solid fuel and a preferred method of manufacturing the same.

상기한 기술적 과제를 해결하기 위해 본 발명은, 폐페인트가 가연성 발포폼용 조성물과 혼합된 후 발포되어 폐페인트 발포폼으로 성형된 것을 특징으로 하는 폐페인트 발포 고체연료를 제공한다. 여기서 가연성 발포폼용 조성물은 발포우레탄폼 조성물을 바람직하게 사용할 수 있다.In order to solve the above technical problem, the present invention provides a waste paint foamed solid fuel, characterized in that the waste paint is mixed with a combustible foamed foam composition and then foamed to form a waste paint foam. Here, as the composition for combustible foam, a foamed urethane foam composition may be preferably used.

또한 본 발명은 폐페인트 발포 고체연료를 제조하는 방법으로, 폴리올 100중량부에 이소시아네이트 60~80중량부를 혼합하여 발포우레탄폼 조성물을 준비하는 제1단계; 발포우레탄폼 조성물 5~10중량%와, 폐페인트 90~95중량%를 혼합 교반하여 발포재료를 준비하는 제2단계; 발포재료를 발포 성형하는 제3단계;를 포함하여 이루어지는 것을 특징으로 하는 폐페인트 발포 고체연료의 제조방법을 제공한다. 여기서 제3단계는 발포재료를 압출 발포하여 성형한 후 절단하면서 이루어질 수 있다.In addition, the present invention is a method of manufacturing a waste paint foamed solid fuel, the first step of preparing a foamed urethane foam composition by mixing 60 to 80 parts by weight of isocyanate to 100 parts by weight of polyol; A second step of preparing a foam material by mixing and stirring 5 to 10% by weight of a foamed urethane foam composition and 90 to 95% by weight of waste paint; It provides a method for producing a waste paint foamed solid fuel, characterized in that comprising; a third step of foaming the foam material. Here, the third step may be performed while cutting the foam material by extrusion foaming and molding it.

본 발명에 따르면 다음과 같은 효과를 기대할 수 있다.According to the present invention, the following effects can be expected.

첫째, 본 발명에 따른 폐페인트 발포 고체연료는 폐페인트를 발포 성형함으로써 액상의 폐페인트가 고상화되면서 폐페인트 내부에 기공이 형성되는 구조로 완성되며, 이로써 내부 기공을 통해 산소 유입을 효과적으로 유도하면서 완전 연소가 가능해져 재활용 고체연료로서 유리하게 활용할 수 있다. First, the waste paint foamed solid fuel according to the present invention is completed in a structure in which pores are formed inside the waste paint while the liquid waste paint is solidified by foaming the waste paint, thereby effectively inducing the inflow of oxygen through the internal pores. Since complete combustion is possible, it can be advantageously utilized as a recycled solid fuel.

둘째, 폐페인트를 발포 성형하여 고상화하기 때문에 간편하게 고체연료로 제조할 수 있다.Second, since the waste paint is foamed and solidified, it can be easily manufactured into solid fuel.

도 1은 본 발명에 따른 폐페인트 발포 고체연료의 제조순서도이다.1 is a flow chart of manufacturing a waste paint foamed solid fuel according to the present invention.

이하 첨부한 도면 및 바람직한 실시예에 따라 본 발명을 설명한다.Hereinafter, the present invention will be described according to the accompanying drawings and preferred embodiments.

본 발명은 폐페인트 발포 고체연료에 관한 것으로, 폐페인트가 가연성 발포폼용 조성물과 혼합된 후 발포되어 폐페인트 발포폼으로 성형된 것을 특징으로 한다. 다시 말해 폐페인트를 발포 성형시킴으로써 액상상태의 폐페인트를 발포폼으로 고정시켜 반고상 상태로 바꾸는 한편, 폐페인트 내부에 발포폼에 의해 기공이 형성되게 한 것이다. 이로써 본 발명에 따른 폐페인트 발포 고체연료는 기공구조가 되어 기공 내에 산소를 포함할 수 있게 되면서 소각시 완전 연소가 가능해진다. 특히 폐페인트는 점력이 있고 소각할 때 같은 성분끼리는 서로 끌어당기는 인장력이 발생하게 되는데, 본 발명에 따른 폐페인트 발포 고체연료를 소각시키면 폐페인트의 점력으로 서서히 부풀어 오르면서 기공이 커지게 되고 더불어 기공 내 산소가 기공 밖의 산소를 끌어당겨 유입시키게 되면서 완전 연소가 가능해지며, 이로써 완전 연소에 의해 유독 가스 발생을 줄이면서 재로 변하게 할 수 있게 된다.The present invention relates to a waste paint foamed solid fuel, characterized in that the waste paint is mixed with a combustible foaming foam composition and then foamed to form a waste paint foam. In other words, by foaming the waste paint, the liquid waste paint is fixed with foamed foam to change it to a semi-solid state, while pores are formed inside the waste paint by the foamed foam. Accordingly, the waste paint foamed solid fuel according to the present invention has a pore structure and can contain oxygen in the pores, thereby enabling complete combustion during incineration. In particular, waste paint has a viscous force, and when incinerated, tensile forces that attract the same components to each other are generated.When the waste paint foamed solid fuel according to the present invention is incinerated, the pores are enlarged while gradually swelling due to the viscous force of the waste paint. As the oxygen inside the pores attracts and introduces oxygen outside the pores, complete combustion becomes possible, thereby reducing the generation of toxic gases and turning into ash by complete combustion.

본 발명에서 폐페인트를 발포하기 위한 가연성 발포폼용 조성물로는 발포우레탄폼 조성물을 바람직하게 이용할 수 있다. 발포우레탄폼 조성물은 가연성이 좋고 자재수급이 용이하면서 저렴하고, 또한 폐페인트와 함께 300℃ 전후에서 점화가 되고 열분해를 시작한다. 발포우레탄폼 조성물은 일반적인 사용범위에서 적용하며, 가령 폴리올 100중량부에 이소시아네이트 60~80중량부를 혼합하면 적당하다. In the present invention, as a composition for a combustible foam for foaming waste paint, a foamed urethane foam composition may be preferably used. The foamed urethane foam composition has good flammability, is easy to supply and supplies, and is inexpensive. Also, it is ignited at around 300°C with waste paint and begins pyrolysis. The foamed urethane foam composition is applied within a general range of use, and for example, 60 to 80 parts by weight of isocyanate are mixed with 100 parts by weight of polyol.

폐페인트 발포 고체연료는, 발포우레탄폼 조성물을 준비한 후 발포우레탄폼 조성물에 폐페인트를 혼합 교반하여 발포재료를 준비하고, 발포재료를 발포시켜 발포폼으로 성형함으로써 제조한다. 즉, 발포우레탄폼 조성물이 폐페인트 내부에 적절하게 혼입되게 한 후 발포가 진행되게 함으로써 폐페인트 내부 사이에 기공이 형성되게 한 것이다. 이로써 액상인 폐페인트가 반고상 상태가 된다.The waste paint foamed solid fuel is prepared by preparing a foamed urethane foam composition and then mixing and stirring waste paint with the foamed urethane foam composition to prepare a foaming material, and then foaming the foaming material to form a foamed foam. That is, the foamed urethane foam composition is appropriately incorporated into the waste paint, and then foaming proceeds, thereby forming pores between the inside of the waste paint. As a result, the liquid waste paint is in a semi-solid state.

구체적으로 폐페인트 발포 고체연료의 제조방법을 살펴보면, 폴리올 100중량부에 이소시아네이트 60~80중량부를 혼합하여 발포우레탄폼 조성물을 준비하는 제1단계; 발포우레탄폼 조성물 5~10중량%와, 폐페인트 90~95중량%를 혼합하여 발포재료를 준비하는 제2단계; 발포재료를 발포 성형하는 제3단계;를 포함하여 이루어진다. 여기서 제3단계는 발포재료를 압출 발포하여 성형한 후 사용 편의를 고려한 크기로 절단하면서 이루어질 수 있다. 한편 제2단계에서 폐페인트와 우레탄폼의 배합비율은 폐페인트 사용을 최대화하면서 발포 성형효과를 고려한 결과이다.Specifically, looking at the manufacturing method of the waste paint foamed solid fuel, a first step of preparing a foamed urethane foam composition by mixing 60 to 80 parts by weight of isocyanate to 100 parts by weight of polyol; A second step of preparing a foam material by mixing 5 to 10% by weight of a foamed urethane foam composition and 90 to 95% by weight of waste paint; It comprises a; a third step of foaming the foam material. Here, the third step may be performed by extruding the foaming material and molding it, and then cutting it into a size considering the convenience of use. Meanwhile, the mixing ratio of waste paint and urethane foam in the second step is the result of considering the foam molding effect while maximizing the use of waste paint.

이상에서 본 발명은 구체적인 실시예를 참조하여 상세히 설명되었으나, 실시예는 본 발명을 예시하기 위한 것일 뿐이므로, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 치환, 부가 및 변형된 실시 형태들 역시 아래에 첨부한 청구범위에 의하여 정하여지는 본 발명의 보호범위에 속한다고 할 것이다.In the above, the present invention has been described in detail with reference to specific examples, but since the examples are only for illustrating the present invention, substitutions, additions, and modified embodiments within the scope not departing from the technical spirit of the present invention are also described below. It will be said that it belongs to the scope of protection of the present invention as defined by the claims attached to.
