본 발명은 폐본드 재생에 관한 것으로, 더욱 상세하게는 제품을 마스킹한 후 버려지는 폐본드를 재생하여 재사용할 수 있도록 하는 폐본드 재생방법에 관한 것이다.The present invention relates to waste bond recycling, and more particularly, to a waste bond recycling method for reusing and recycling waste bonds discarded after masking a product.

일반적으로 제품을 아노다이징할 때 전체 또는 부분적으로 아노다이징을 할 경우가 있는데, 부분적으로 아노다이징을 행할 경우는 아노다이징이 불필요한 부분에 마스킹액(본드)을 도포하여 건조시킨 후 수조탱크에 제품을 담수시켜 아노다이 징을 행하게 된다.In general, when anodizing a product, anodizing may be performed in whole or in part.In the case of partially anodizing, a masking liquid (bond) is applied to a part where anodizing is unnecessary and dried, and then the product is dehydrated in a tank tank. Gong will be done.

아노다이징이 완료된 후 제품을 건조시킨 후 마스킹액을 제거함으로써 소정의 아노다이징이 완료된다.After the anodizing is completed, the predetermined anodizing is completed by drying the product and removing the masking liquid.

도 1은 일반적으로 제품에 부분 아노다이징을 행하는 공정을 설명하기 위한 도면이다.1 is a diagram for generally explaining a step of performing partial anodizing on a product.

도면을 참조하면, 피도물(10)에 부분적으로 아노다이징을 행하고자 할 경우에는 피막처리하기 위한 아노다이징부(11)와 아노다이징이 필요치 않는 마스킹부(12)로 구분된다. 상기 마스킹부(12)에는 마스킹액(본드)을 도포한 후 건조시킨 상태에서 소정의 아노다이징을 행하게 되고, 이후 마스킹된 부분의 본드를 제거하게 된다.Referring to the drawings, in order to partially anodize the workpiece 10, it is divided into an anodizing portion 11 for coating and a masking portion 12 that does not require anodizing. The masking part 12 is coated with a masking liquid (bond) and then subjected to a predetermined anodizing in a dried state, and then removes the bond of the masked part.

그러나 제품을 아노다이징한 후 버려지는 폐본드는 매립장에 매립처리하게 되는데, 이러한 폐본드는 매립시 자연 분해가 되는데 오랜 세월이 지나도 분해되지 않는 산업폐기물로서 매립지를 오염시키는 문제가 있다. However, the waste bonds discarded after anodizing the product are landfilled in the landfill, and these waste bonds are naturally decomposed at landfill, and there is a problem of polluting the landfill as industrial waste that does not decompose even after many years.

본 발명은 이러한 종래 문제를 해결하기 위한 것으로, 특히 제품을 아노다이징 후 버려지는 폐본드를 재생하여 사용할 수 있도록 함으로써 쓰레기의 배출량을 줄이고, 동시에 원가를 절감할 수 있도록 하는 폐본드 재생방법을 제공하는데 그 목적이 있다.The present invention is to solve this conventional problem, in particular to provide a waste bond regeneration method that can reduce the amount of waste, and at the same time reduce the waste by making it possible to recycle the waste bond discarded after anodizing the product. There is a purpose.

상기 목적을 달성하기 위한 본 발명의 폐본드 재생방법은 a)폐본드 67-73중량%, 크실렌 25-30중량%, 톨루엔 2-5중량%를 용기에 혼합하여 일정시간 방치함으로써 폐본드를 점액질 상태로 변환시키는 단계; b)상기 a)단계 후 용기에 담겨진 점액질 상태의 폐본드를 스크류로 회전하여 교반시키는 단계; 및 c)상기 b)단계의 과정에 의해 용해되어 점액화된 폐본드에 포함된 이물질을 걸름망을 통해 분리하는 단계:를 포함하는 것을 특징으로 한다.Waste bond regeneration method of the present invention for achieving the above object is a) mucosa of the waste bond by leaving the waste bond 67-73% by weight, 25-30% by weight of xylene, 2-5% by weight of toluene in a container for a certain time Converting to a state; b) a step of rotating the waste bond in the slime state in the container after the step a) with a screw to stir; And c) separating the foreign matter contained in the waste bond dissolved and slime by the process of step b) through a strainer.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 폐본드 재생방법을 설명하기 위한 순서도이다. 일반적으로 제품을 아노다이징 처리할 경우 아노다이징이 불필요한 부분을 마스킹액으로 도포하여 건조한 상태에서 아노다이징을 행하게 된다.2 is a flowchart illustrating a waste bond recycling method according to the present invention. In general, when the product is anodized, anodizing is unnecessary, and the anodizing is performed in a dry state by applying a masking liquid.

아노다이징이 완료된 후 마스킹된 부분을 제거하게 되는데, 이때 제거되는 폐본드를 일정한 크기의 용기에 담고, 크실렌과 톨루엔액을 주입한다(S21).After the anodizing is completed, the masked part is removed. At this time, the removed waste bond is placed in a container of a predetermined size, and xylene and toluene solution are injected (S21).

이때, 상기 폐본드, 크실렌 및 톨루엔의 함량은 폐본드 67-73중량%, 크실렌 25-30중량%, 톨루엔 2-5중량%가 좋다.At this time, the content of the waste bond, xylene and toluene is preferably 67-73% by weight of the waste bond, 25-30% by weight of xylene, 2-5% by weight of toluene.

폐본드의 량이 크실렌과 톨루엔의 량에 비해 과다할 경우 폐본드의 용해가 불량해지고, 반대로 크릴센과 톨루엔의 량이 폐본드에 비해 과다할 경우 용액질이 묽어져 일정한 점도를 유지하기 어렵기 때문에 폐본드 70중량%, 크실렌 27중량%, 톨루엔 3중량%의 비율로 혼합하는 것이 바람직하다.When the amount of the waste bond is excessive compared to the amount of xylene and toluene, the dissolution of the waste bond becomes poor. On the contrary, when the amount of krillsen and toluene is excessive compared to the waste bond, the solution is thin and it is difficult to maintain a constant viscosity. It is preferable to mix in the ratio of 70 weight%, 27 weight% of xylene, and 3 weight% of toluene.

이와 같이 폐본드에 대해 크실렌과 톨루엔액을 혼합하면, 상기 폐본드가 크실렌과 톨루엔액에 의해 서서히 반응하면서 용해되기 시작하게 되는데, 본 발명은 이러한 과정에서 혼합기로 용해액을 일정시간 교반시켜줌으써 용해의 정도 및 용해 시간을 줄인다(S22).As such, when the xylene and toluene solution are mixed with the waste bond, the waste bond starts to dissolve while slowly reacting with the xylene and toluene solution, and the present invention dissolves the solution by stirring the solution with a mixer for a predetermined time. Reduce the degree and dissolution time (S22).

상기 단계 S22의 과정이 완료되면, 고체상태의 폐본드는 완전히 용해되어 일정한 점도를 갖는 점액질로 변하게 되는데, 이후 점액질 속에 함유된 부유물이나 또는 이물질을 제거하는 과정을 수행하게 된다(S23).When the process of step S22 is completed, the solid waste bond is completely dissolved into a mucus having a constant viscosity, and then a process of removing suspended matter or foreign matter contained in the mucus is performed (S23).

본 발명은 폐본드가 용해된 점액질으로부터 양호한 마스킹액을 재생할 수 있도록 메쉬정도가 미세한 걸름망에 점액질을 통과시켜 이물질을 제거한다.The present invention removes foreign substances by passing the mucus through a strain mesh having a fine mesh degree so that a good masking liquid can be reproduced from the mucus in which the waste bond is dissolved.

이와 같이 점액질로부터 이물질을 제거하는 과정은 향후 아노다이징에 마스킹액을 재사용할 경우 이물질에 의해 아노다이징의 불량을 방지할 수 있도록 하기 위한 것이다. As such, the process of removing the foreign matter from the mucus is intended to prevent the defect of the anodizing by the foreign matter when the masking liquid is reused in the future anodizing.

이상에서 설명한 바와 같이, 본 발명은 아노다이징에 사용된 고체상태의 폐본드를 용해액과 혼합하여 일정한 점도를 갖는 용액질로 반응시킨 후 이물질을 제거하는 과정을 완료함으로써 폐본드로부터 양질의 마스킹액을 재생할 수 있어, 산업폐기물의 배출량을 감소시키고, 더욱이 폐본드를 재생하여 아노다이징시 마스킹에 재사용함으로서 제품 생산의 원가를 절감할 수 있는 효과가 있다. As described above, the present invention is to recycle the high quality masking liquid from the waste bond by completing the process of removing the foreign matter after mixing the solid waste bond used for anodizing with the solution to react with a solution of a certain viscosity It is possible to reduce the amount of industrial waste, and furthermore, it is possible to reduce the cost of product production by recycling waste bonds and reusing them for masking during anodizing.

상술한 바와 같이 본 발명의 바람직한 실시예를 참조하여 설명하였지만 이는 본 발명의 가장 양호한 실시예를 예시적으로 설명한 것이지 본 발명을 한정하는 것은 아니다. 또한, 이 기술분야의 통상의 지식을 가진 자이면 누구나 본 발명의 기술사상의 범주를 이탈하지 않는 범위 내에서 다양한 변형 및 모방이 가능함은 명백한 사실이다.Although described with reference to a preferred embodiment of the present invention as described above it is illustrative of the best embodiment of the present invention by way of example, not limiting of the invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
