Description

폐페인트 발포 고체원료 및 그 제조방법{Solid Fuel foamed Waste Paint and Manufacturing Method Thereof}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to solid fuel foamed solid materials,

본 발명은 폐페인트 발포 고체원료 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.More particularly, the present invention relates to solid-state production technology for use as a heat source for use in a power plant, a cement kiln, etc. by foaming and molding the collected waste paint into semi-solid or solid phase .

폐페인트는 고상, 반고상, 액상 등 3종류로 구분되고 대부분 액상이 주종을 이루고 있으며, 그 종류로는 폐페인트와 폐락카가 있다. The waste paint is divided into three types, solid, semi-solid and liquid. Most of the liquids are mainly composed of 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 mostly incinerated as it is currently collected in an incinerator. Generally, when the waste paint is incinerated, the supply of oxygen to the inside of the waste paint is not smooth, the combustion is slow, and black smoke and toxic gas are generated, and a facility for eliminating or reducing it is required. Because of this problem, waste paint has a lot of calorific value and it is generally enough to use as a major alternative energy source. However, it is generally burned as it is, and research for effective recycling of waste paint is needed.

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 fueling waste paint has been developed and proposed. For example, Korean Patent Registration No. 10-0503347 (method of manufacturing solid fuel using waste paint, dust and sludge) 10-0560700 (method of producing solid fuel using waste paint), Korean Patent Registration No. 10-0661875 (flammable solid fuel using waste paint), Korean Patent Registration No. 10-0767757 (recycled fuel oil using waste paint And a method for producing the same).

대한민국특허등록 제10-0560700호Korean Patent Registration No. 10-0560700 대한민국특허등록 제10-0661875호Korean Patent Registration No. 10-0661875

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 고체원료와 이의 바람직한 제조방법을 제공하는데 기술적 과제가 있다.The present invention has been developed for recycling as a solid fuel of waste paint, and it has been developed as a method for recycling waste paint, which is produced by foaming waste paint and forming it into a foamed foam of semi-solid or solid shape having pores formed therein, There is a technical problem in providing a paint-foamed solid raw material and a preferable production method thereof.

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-mentioned technical problem, the present invention provides a waste paint foamed solid fuel characterized in that the waste paint is mixed with a composition for a combustible foam foam and foamed to form a waste paint foam foam. Here, the foamable urethane foam composition can be preferably used as the composition for the combustible foam foam.

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.The present invention also provides a method for producing a waste foamed solid fuel, comprising the steps of: preparing a foamed urethane foam composition by mixing 60 to 80 parts by weight of an isocyanate with 100 parts by weight of a polyol; 5 to 10% by weight of a foamed urethane foam composition and 90 to 95% by weight of a waste paint are mixed and stirred to prepare a foamed material; And a third step of foaming and molding the foamed material. The present invention also provides a method for producing a foamed solid foam fuel. Here, the third step may be performed while extruding the foaming material, molding it, and then cutting 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 with the structure in which the liquid waste paint is solidified by forming the foam paint into foam, and the pores are formed inside the waste paint, thereby effectively inducing the oxygen inflow through the inner pores It is possible to completely utilize it as a solid fuel for recycling.

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 as a solid fuel.

도 1은 본 발명에 따른 폐페인트 발포 고체연료의 제조순서도이다.BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a flow chart of the production of a waste paint foamed solid fuel according to the present invention.

이하 첨부한 도면 및 바람직한 실시예에 따라 본 발명을 설명한다.BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described with reference 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 foamed after being mixed with a composition for a combustible foam foam and molded into a waste paint foam foam. In other words, the waste paint is foam-molded so that the waste paint in the liquid state is fixed with the foam foam to the semi-solid state and the pores are formed by the foam foam inside the waste paint. As a result, the waste plastic foamed solid fuel according to the present invention has a pore structure and can contain oxygen in the pores, thereby enabling complete combustion at the time of incineration. Particularly, when the waste paint has a point and is incinerated, pulling forces of the same components pull each other. When the waste paint foamed solid fuel according to the present invention is incinerated, the pores are gradually swollen due to the force of the waste paint, Oxygen pulls oxygen out of the pores and allows it to be completely burned, which makes it possible to reduce the toxic gas generation by ashing by the 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 the composition for combustible foam foam for foaming waste paint, a foamed urethane foam composition can be preferably used. The foamed urethane foam composition is good in flammability, is inexpensive because it is easy to supply and receive materials, and ignites at around 300 ° C together with the waste paint and starts pyrolysis. The foamed urethane foam composition is applied in a general use range, for example, when 60 to 80 parts by weight of isocyanate is 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 plastic foamed solid fuel is prepared by preparing a foamed urethane foam composition, mixing and stirring the foamed urethane foam composition with a waste paint to prepare a foamed material, and foaming the foamed material to form a foamed foam. That is, after the foamed urethane foam composition is appropriately mixed into the waste paint, the foaming proceeds so that pores are formed between the inside of the waste paint. As a result, the liquid waste paint becomes semi-solid.

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, a method for producing a solid fuel for pulverized foamed paint includes: a first step of preparing a foamed urethane foam composition by mixing 60 to 80 parts by weight of an isocyanate with 100 parts by weight of a polyol; 5 to 10% by weight of a foamed urethane foam composition and 90 to 95% by weight of a waste paint to prepare a foamed material; And a third step of foaming and molding the foamed material. Here, the third step may be performed while extruding the foaming material, molding the foaming material, cutting it into a size considering convenience for use. On the other hand, in the second step, the blending ratio of the waste paint and the urethane foam is a result of considering the foam molding effect while maximizing the use of the 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.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, the present invention is not limited to the above-described exemplary embodiments, and various modifications, additions and substitutions may be made without departing from the scope of the present invention. The scope of which is defined by the claims appended hereto.
