Description
본 발명은 폐 배터리 재생처리 과정시 발생하는 연진을 성형체로 제조하는 방법에 관한 것으로, 보다 상세하게는 연진을 결합제와 균일혼합 후 압출성형에 의해 연속적으로 성형체를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a dust generated during the waste battery regeneration process into a molded body, and more particularly to a method for continuously producing a molded body by extrusion molding after mixing the dust with a binder.
최근, 자동차의 수요가 급증함에 따라, 자동차용 배터리의 수요도 크게 증가하고 있는 실정이다. 이에 따라, 발생되는 폐 배터리의 양도 기하급수적으로 증가하는데, 이와 더불어 폐 배터리의 재활용문제도 사회적인 문제로 대두되고 있다.Recently, as the demand for automobiles soared, the demand for automobile batteries has also increased significantly. Accordingly, the amount of waste batteries generated increases exponentially, and the recycling of waste batteries is also a social problem.
이러한 폐 배터리의 문제를 해결하기 위하여, 폐 배터리 내의 납폐기물을 회수하여 재활용하려는 노력이 진행되고 있다. 일례로, 폐 배터리내의 납폐기물을 플라스틱 등의 케이스재와 분리한 다음, 용융 가열로 내에 코크스, 석회석, 철 스크랩 등과 같이 투입하여 용융 환원시켜 회수하여 재활용하는 경우도 있다. 그러나, 이러한 과정에서 폐 납화합물의 일부가 미크론 크기의 아주 미세한 입자형태로 배출되기 때문에, 이들 처리에 많은 어려움을 겪고 있는 실정이다. 특히, 납 화합물은 특정 폐기물로서 폐기 처리시 매우 엄격한 규제를 받게 되며, 이러한 물질들이 환경오염을 유발시킬 경우 사회적으로 대단히 중대한 질병을 야기 시키게 된다.In order to solve this problem of the waste battery, efforts are being made to recover and recycle lead waste in the waste battery. For example, the lead waste in the waste battery may be separated from a case material such as plastic, and then poured into a melting furnace, such as coke, limestone or iron scrap, to be melted, recovered and recycled. However, in this process, some of the waste lead compounds are discharged in the form of very fine particles having a size of micron, and thus, many treatments have been difficult. In particular, lead compounds are subject to very strict regulations for disposal as specific wastes, and if these substances cause environmental pollution, they can cause serious social illness.
따라서, 최근에는 이러한 연진들의 재활용을 위한 노력이 이루어지고 있으며, 그중 연진을 결합재를 사용하여 성형체를 제조한 후, 재 용융 가열로에 투입 처리하는 방법이 제시되고 있다. 그러나, 이 기술에서는 제조된 성형체를 용해로내에 장입하는 과정에서 로상부의 고온으로 인하여 재용융하는 문제가 있다.Therefore, in recent years, efforts have been made to recycle these dusts. Among them, a method has been proposed in which a dust is manufactured using a binder and then subjected to a remelting furnace. However, in this technique, there is a problem of remelting due to the high temperature of the upper part in the process of charging the produced molded product into the melting furnace.
이에, 본 발명자는 상기와 같은 문제점을 해결하기 위하여 연구와 실험을 거듭하고 그 결과에 근거하여 본 발명을 제안하게 된 것으로, 본 발명은 연진과 결합제를 가열혼합한 후, 가열공정을 거치지 않고 바로 가압성형에 의해 성형체를 연속적으로 제조함으로써, 제조비용을 저감하고 품질향상을 도모함은 물론, 설비를 단순화할 수 있는 연속식 연진 성형체의 제조방법을 제공하고자 하는데, 그 목적이 있다.Accordingly, the present inventors have repeatedly conducted research and experiments to solve the above problems, and suggest the present invention based on the results, and the present invention heat-mixes the dust and the binder, and then immediately goes through the heating process. By continuously producing a molded body by press molding, it is intended to provide a method for producing a continuous continuous molded article that can reduce manufacturing costs and improve quality as well as simplify equipment.
상기한 목적을 달성하기 위한 본 발명은,The present invention for achieving the above object,

이하, 본 발명에 대하여 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated.
본 발명의 발명자는, 폐 배터리 재생처리 과정에서 발생하는 연진을 성형체로 제조하여 재활용함으로써, 환경문제를 해결하고자 하는 목적으로 본 발명을 완성시킨 것이다. 이 때, 본 발명에서는 연진 성형체의 제조시 점결성을 부여하기 위해 점결재를 첨가하였는데, 바람직한 점결재로는, 용융점이 300℃이하인 고분자수지, 특히, 페놀수지, 퓨란수지, 또는 변성피치 등이 있다. 상기 점결재의 함량은, 10~20중량%로 설정하는 것이 바람직한데, 그 이유는 상기 점결재의 함량이 10중량%미만이면 연진 표면을 충분히 피복하기 어려워 충분한 성형강도를 나타낼 수 없으며, 20중량%를 초과하는 경우에는 점결재 사용량의 증가로 인한 원가 상승과 연진의 처리량 감소 등으로 제조비용이 증가하기 때문이다.The inventors of the present invention have completed the present invention for the purpose of solving environmental problems by manufacturing and recycling dust generated in a waste battery regeneration process into a molded body. At this time, in the present invention, a caking additive was added in order to impart caking properties in the manufacture of the lead-molded article, and preferred caking additives include polymer resins having a melting point of 300 ° C. or lower, in particular, phenol resins, furan resins, or modified pitches. . The content of the caking additive is preferably set to 10 to 20% by weight. The reason for this is that when the content of the caking additive is less than 10% by weight, it is difficult to sufficiently cover the dusty surface and thus may not exhibit sufficient molding strength, and 20 wt%. If it exceeds the percentage, manufacturing costs will increase due to higher costs resulting from increased use of caking additives and lower throughput.
상기와 같이 점결재가 첨가된 연진 혼합물을 가열 혼합하는데, 200~300℃의 온도범위에서 10∼30분간 혼합하는 것이 바람직하다. 즉, 상기 온도가 200℃ 미만이거나 혼합시간이 10분 미만일 경우에는 충분한 혼합효과를 기대하기 어렵고, 300℃를 넘거나 30분을 초과할 경우에는 에너지 소비증가에 따른 비용증가와 생산성 저하 의 문제가 있다.As above-mentioned, although the thermally mixed mixture to which the caking additive was added is heat-mixed, it is preferable to mix for 10 to 30 minutes in the temperature range of 200-300 degreeC. That is, if the temperature is less than 200 ℃ or less than 10 minutes of mixing time it is difficult to expect a sufficient mixing effect, if the temperature exceeds 300 ℃ or more than 30 minutes, the problem of increased cost and productivity decrease due to increased energy consumption have.
그 후, 상기 가열 혼합된 혼합물을 가압주형 성형기를 이용해 압출성형하여연진 성형체로 연속제조한다.Thereafter, the heat-mixed mixture is extruded using a pressure casting machine to continuously produce a lead-forming body.
일반적으로 분말상 물질을 성형하는 방법으로는, 상온에서 형틀에 원료를 장입한 후 가압하여 성형체로 제조하는 상온 가압성형법과, 형틀에 원료를 장입한 후 고온으로 승온하여 소결성형하는 소결성형방법이 있는데, 상기 상온 가압 성형법은 원료물질이 점결성을 보유하거나, 점결재가 첨가되어 성형만으로도 사용이 가능한 원료의 성형에 사용되며, 상기 소결성형법은 원료물질이 자체적으로는 점결성이 없거나 점결재를 사용하여도 성형만으로는 사용이 불가능한 원료의 성형에 사용된다. 또한, 소결성형법은 고온에서의 기계적 강도가 요구되는 경우 사용된다.In general, there are two methods for molding a powdery substance, which are a normal temperature press molding method in which a raw material is charged into a mold at room temperature and then pressurized to form a molded body, and a sinter molding method in which a raw material is charged into a mold and then heated to a high temperature to be sintered and molded. In addition, the room temperature pressure molding method is used for the molding of a raw material having a caking property, or a caking material is added and can be used only by molding, the sintering molding method is used even if the raw material itself is not caking or caking material It is used for molding raw materials that cannot be used by molding alone. In addition, the sinter molding method is used when mechanical strength at high temperature is required.
본 발명에서는 상기 상온 가압 성형법과 소결성형방법의 이용이 모두 가능하다. 다만, 본 발명은 연진에 점결재를 첨가하여 점결성을 확보하고 있기 때문에, 상기 상온 가압 성형법을 사용하는 것이 가능하고, 이로 인해 제조공정을 단순화하고 처리비용을 저감하여 경제성을 확보할 수 있는 것이다.In the present invention, both the normal pressure molding method and the sintering molding method can be used. However, in the present invention, since the caking property is secured by adding a caking additive to the dust, it is possible to use the above-mentioned pressure molding method at room temperature, thereby simplifying the manufacturing process and reducing the processing cost, thereby securing economical efficiency.
이와 같이 하여 제조된 본 발명의 연진 성형체는, 100kg/㎠이상의 압축강도를 나타낼 뿐 아니라, 안정적으로 연속제조가 가능하다.The lead-molded article of the present invention thus produced not only exhibits a compressive strength of 100 kg / cm 2 or more, but can also be stably manufactured continuously.
이하, 실시예를 통하여 본 발명을 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to Examples.
(실시예)(Example)
연진과 점결재가 하기 표 1의 비율로 혼합된 연진 혼합물을 가열기가 부착된 혼합장치를 이용해 분당 50rpm의 회전속도로 가열혼합하였다. 이 때, 상기 가열혼합장치는 5℃/min의 속도로 승온되었고, 가열혼합시간 및 온도는 하기 표 1과 같이 변화시켰다.The dust mixture mixed with the dust and caking additives in the ratio of Table 1 was heat mixed at a rotational speed of 50 rpm per minute using a mixer equipped with a heater. At this time, the heat mixing apparatus was heated up at a rate of 5 ℃ / min, the heat mixing time and temperature was changed as shown in Table 1 below.
이와 같이 하여, 혼합이 완료된 혼합물을 압출 성형기에 투입한 후, 압출하여 성형체로 제조하였다. 이후, 제조된 성형체의 압축강도를 측정하고, 그 결과를 하기 표 1에 나타내었다.In this way, the mixture after mixing was put into an extrusion molding machine, and then extruded to produce a molded body. Then, the compressive strength of the manufactured molded product was measured, and the results are shown in Table 1 below.
상기 표 1에 나타난 바와 같이, 점결제와 연진이 본 발명범위로 혼합되고, 200~300℃의 온도에서 10~30분간 혼합되어 성형체로 제조된 발명예(1)~(9)의 경우에는, 모두 압축강도가 100kg/㎠이상인 것을 알 수 있다.As shown in Table 1 above, in the case of Inventive Examples (1) to (9), the binder and the dust are mixed in the present invention range, and are mixed into a molded body for 10 to 30 minutes at a temperature of 200 to 300 ° C. It can be seen that all of the compressive strength is more than 100kg / ㎠.
상기한 바와 같은 본 발명에 의하면, 압축강도가 우수한 연진 성형체를 연속제조할 수 있어서, 제조비용을 저감하고 품질향상을 도모함은 물론, 설비를 단순화할 수 있는 효과가 있는 것이다.According to the present invention as described above, it is possible to continuously manufacture a lead-molded article excellent in compressive strength, thereby reducing the manufacturing cost, improving the quality, and has the effect of simplifying the equipment.
