본 발명은 폐기 동슬래그를 이용한 탈취소재에 관한 것으로, 특히 동(Cu) 제련시에 발생하여 폐기되는 동슬래그를 이용하여 종래의 고가의 탈취에 사용되는 고가의 재료를 대신하는 탈취기능성 조성물에 관한 것이다.The present invention relates to a deodorizing material using waste copper slag, and more particularly to a deodorizing functional composition to replace the expensive material used for the conventional expensive deodorization using copper slag generated and discarded during copper (Cu) smelting will be.
최근 들어 기능성 소재의 개발과 더불어 탈취기능을 갖는 재료의 요구가 증대하고 있으며, 탈취 재료로써는 각종 유기 탈취제와 무기 탈취제가 있으나, 무기탈취제가 지속성 측면에서 유리하여 대부분 금속과 비금속이 무기 탈취제를 사용하고 있다. 매우 고가일 뿐만 아니라, 여러 탈취재료에 사용되기 위해서는 탈취제가 상기 탈취재료에 맞는 적정입자와 형상을 가져야 하므로, 이미 여러 공정을 거쳐제조된 순수 금속이나 산화물을 필요한 입도에 맞춰 일정크기로 다시 분쇄하거나 가공하는 공정을 필요로 하는 매우 보다 복잡한 공정을 갖게되는 것이다.Recently, with the development of functional materials, the demand for materials having a deodorizing function has been increasing, and there are various organic deodorants and inorganic deodorants as deodorizing materials, but inorganic deodorants are advantageous in terms of sustainability, and most metals and nonmetals use inorganic deodorants. have. In addition to being very expensive, in order to be used in various deodorizing materials, the deodorant must have the appropriate particle and shape suitable for the deodorizing material. You have a much more complicated process that requires a process to process.
따라서 상기한 탈취제를 혼화제 또는 첨가제로 다량 사용하게 되는 종래의 탈취도료같은 탈취재료 역시 매우 고가일 수밖에 없어 사용자들에게 상당한 비용부담을 전가하는 폐단을 갖는 것이다.Therefore, deodorant materials such as conventional deodorant paints, which use a large amount of the deodorant as admixtures or additives, are also very expensive and have a closed cost that imposes significant cost on users.
한편 일반적으로 이용되는 자용로공법 동제련은 광석을 이용하여 구리를 제련하고 남는 슬래그를 수쇄하여 작은 입자상을 만드는 것이 일반적인 제조방법이다. 그러나 이러한 공정에서 발생하는 동(Cu)입자는 미세하고 입자가 구형을 유지하고 있기 때문에 샌드블라스팅용 골재로 직접 이용되고 있다. 그러나 최근에 건설된 연속 동제련 슬래그는 그의 조성이 일반 자용로공법 동슬래그와 조성이 다르고 슬래그 처리과정에서 일반 동슬래그 처리과정에서 나오는 입자보다 입도분포가 상향조정되어 있어 건축자재외에는 별다른 용도가 없는 실정이다.On the other hand, commonly used copper smelting method is to smelt copper by using ore and to crush the remaining slag to make a small particulate form. However, the copper (Cu) particles generated in this process is fine and is used directly as a sandblasting aggregate because the particles maintain a spherical shape. However, the recently constructed continuous copper smelting slag has a different composition from the conventional slag copper slag, and the particle size distribution of the continuous slag treatment is higher than that of the general copper slag treatment. It is true.
본 발명자는 이런 동제련시에 발생하는 동슬래그 입자가 수쇄공정을 통해 이미 입도가 적어 졌으며, 특히 탈취성을 나타내는 고가의 구리나 산화구리가 균일하게 분포되어 있는 것에 착안하여 이를 탈취재료의 원료로 사용하고자 하였다.The present inventors noticed that the copper slag particles generated during copper smelting have already been reduced in particle size through a hydrocracking process, and in particular, expensive copper or copper oxides exhibiting deodorizing properties are uniformly distributed and used as a raw material for deodorizing materials. It was intended to be used.
현재 동제련공정 중에 발생하는 동슬래그는 정광 용융 후 마트(matte)용해 후나 부분 배소 후 용융상 용해로부터, 또는 배소반응 후 동 직접 용융시, 슬래그나 슬래그 선광 후에 발생된다.At present, copper slag generated during the copper smelting process is produced after melting the matte after concentrate melting or after melting the molten phase after partial roasting, or after slag or slag beneficiation when copper is directly melted after the roasting reaction.
특히 동슬래그는 ＜표1＞과 같이 자용로공법 및 연속제련공법의 2종류의 공법에 의해 생산되나 자용로공법으로 생산되는 슬래그는 하기의 ＜표2＞와 같이 입도분포가 하향조정되어 있어 현재까지 샌드브라스팅용 골재로만 사용이 되어왔다. 그러나 최근 도입된 연속동제련슬래그는 ＜표2＞에서와 같이 입도가 보다 상향 조정이 되어 있으나 그 종류 슬래그 모두다 입상화 되어 있어 본 발명자는 이에 착안하여 동제련 슬래그를 직접 또는 가공하여 탈취제 원료로 사용하고자 하였다.In particular, copper slag is produced by two kinds of processes, namely, self-furnace method and continuous smelting method as shown in <Table 1>, but the particle size distribution is adjusted downward as shown in <Table 2>. It has been used only as aggregate for sand blasting. However, the recently introduced continuous copper smelting slag has been further increased in particle size as shown in <Table 2>, but all kinds of slag have been granulated, so the present inventors noticed that the copper smelting slag was processed directly or as a deodorant raw material. It was intended to be used.

이처럼 본 발명은 종래의 무기제 및 금속 탈취제가 매우 고가이기 때문에 범용하기 곤란한 것이므로, 이를 대체하기 위한 재료로써 동제련과정에서 발생하는 동슬래그가 금속성분으로 구리와 산화동(CuO)을 함유하고 있으므로, 이를 탈취제 원료로 사용하고자 직접 또는 이를 분쇄하고 체질을 통해 적정크기의 입자를 얻은후, 산화 처리함으로써 종래 탈취 재료의 탈취제를 대체할 수 있는 탈취제를 얻을 수 있는 것이다.As described above, the present invention is difficult to use because the conventional inorganic and metal deodorant are very expensive, and as a material for replacing the copper slag generated during the smelting process, it contains copper and copper oxide (CuO) as metals. In order to use this as a deodorant raw material, it can be obtained by directly or by pulverizing and obtaining particles of a proper size through sieving, and then oxidizing to deodorant which can replace the deodorant of the conventional deodorant material.
따라서 종래 거의 모두 폐기되던 동슬래그를 활용하여 저렴한 가격의 탈취재료를 제조할 수 있으며, 부수적으로 폐 자원을 재활용하게됨으로써 환경오염 방지와 해양을 개발하는데 큰 도움이 되는 것이다.Therefore, it is possible to manufacture a deodorizing material at a low price by using copper slag, which has been almost discarded in the past, and by recycling waste resources incidentally, it is a great help in preventing pollution and developing the ocean.
본 발명의 구성을 상세히 설명하면 다음과 같다. 본 발명은 동제련 과정중에 발생하여 폐기되는 동슬래그를 이용한 종래 탈취제의 대체제를 제조하기 위한 방법에 관한 것으로, 현재 동제련공정 중에 발생하는 동슬래그는 정광 용융 후 마트(matte)용해 후나 부분배소 후 용융상 용해로부터, 또는 배소반응 후 동 직접용융시, 슬래그나 슬래그선광 후에 발생된다.Referring to the configuration of the present invention in detail as follows. The present invention relates to a method for manufacturing a substitute for a conventional deodorant using copper slag generated and discarded during the copper smelting process, the copper slag generated during the current copper smelting process after the melting of the concentrate after matte melting or after partial roasting Either from melting of the melt phase or from copper direct melting after roasting reaction, after slag or slag beneficiation.
상기 동슬래그의 입도분포는 다음과 같다. 수쇄되어 입자상으로 발생되는 폐슬래그를 탈취재료로 직접 사용하거나 분쇄, 체질을 통해 분말 또는 각종입도로 사용되거나 제품의 균일화를 위해 산화처리를 하는 것으로 구성된다.The particle size distribution of the copper slag is as follows. The waste slag generated in the form of crushed particles is directly used as a deodorizing material, or used as a powder or various particles through pulverization and sieving, or is subjected to oxidation treatment for uniformity of the product.
상기 동슬래그의 화학적 조성은 구리(Cu)0.7∼1.1%, 전철분(T-Fe)36.0∼48.0%, 산화칼슘(CaO)0.7∼5.0%, 산화마그네슘(MgO)0.7∼1.2%, 이산화규소(SiO2)27.0∼34.0%, 산화알루미늄(Al2O3)2.5∼5.5%, 산화철(Fe3O4)3∼10%로 이루어져 있으므로 이를 직접 탈취제로 이용하거나, 이를 이용하여 탈취재료의 탈취제를 제조하기 위해서는 상기 동슬래그를 400 ∼ 600℃의 반응로에 직접 넣고환원제를 취입하여 환원시켜서 탈취제를 제조하는 방법과, 탈취재료에 적당한 입도의 탈취제를 얻기 위해서 상기 동슬래그를 햄머밀이나 볼밀에 의해 분쇄하는 분쇄공정과, 상기 분쇄된 동슬래그를 진동밀에 의해 더욱 미분화하는 미분화공정과, 상기 미분화공정에서 얻어진 분말을 체질하여 입도를 조절한 다음 400 ∼ 600℃의 반응로에 넣고 환원제를 취입하여 환원시키는 산화공정에 의해 탈취제를 제조하는 방법으로 이루어진다.The chemical composition of the copper slag is copper (Cu) 0.7 to 1.1%, train powder (T-Fe) 36.0 to 48.0%, calcium oxide (CaO) 0.7 to 5.0%, magnesium oxide (MgO) 0.7 to 1.2%, silicon dioxide (SiO 2 ) 27.0 to 34.0%, aluminum oxide (Al 2 O 3 ) 2.5 to 5.5%, iron oxide (Fe 3 O 4 ) 3 to 10%, so it is used as a direct deodorant, or by using the deodorant of the deodorant material In order to manufacture the copper slag directly into the reactor of 400 ~ 600 ℃ to reduce the blowing agent to reduce the deodorant and to obtain a deodorant of the particle size suitable for the deodorizing material in the hammer mill or ball mill The pulverization process by pulverization, the micronization process of further pulverizing the pulverized copper slag by vibrating mill, and sieving the powder obtained in the pulverization process to adjust the particle size, and then put the reducing agent into a reactor at 400 to 600 ° C By oxidation process It comprises a method for producing a chwije.
발생상태 그대로의 폐동슬래그는 직접 탈취재료로 사용되거나 복합탈취제 제조에 첨가하는 것이 바람직하고, 입도를 갖는 동슬래그는 미분 탈취제로 첨가하는 것이 바람직하다. 상기 입도는 탈취재료와 사용목적에 따라 약간씩 차이가 있을 수 있다.It is preferable to use waste copper slag as it is as a direct deodorizing material or to add the composite deodorant, and to add copper slag having a particle size as a fine powder deodorant. The particle size may vary slightly depending on the deodorizing material and purpose of use.
본 발명 탈취제에 의해 제조된 탈취재료를 실시예에 의해 상세히 설명하면 다음과 같은 바 실시 예에 의해 한정되는 것은 아니다.When the deodorizing material prepared by the present invention deodorant in detail by the embodiment is not limited by the following examples.

＜실시예2의 실험결과＞<Experiment Result of Example 2>
＜실시예3의 실험결과＞<Experiment Result of Example 3>
탈취제를 첨가한 경우와 첨가하지 않은 경우의 탈취효과의 비교를 위하여 일반 시멘트모르타르를 제조하여 실시예 1, 2, 3과 비교하였다. 공시체 제작과 시험조건은 상기의 실시예 1, 2, 3과 동일하게 하였다.General cement mortar was prepared and compared with Examples 1, 2, and 3 in order to compare the deodorizing effect with and without deodorant. Test specimen preparation and test conditions were the same as in Examples 1, 2, and 3 above.
탈취모르타르의 재령 28일 압축강도 특성은 모두 일반 시멘트모르타르에 비해 낮은 수준이었으며, 322kg/㎠로 가장 낮은 수준을 보였다. 그러나 탈취모르타르의 재령 28일 휨강도는 일반 시멘트모르타르에 비해 훨씬 우수하게 나타났다.The 28-day compressive strength characteristics of deodorized mortar were lower than those of general cement mortar, and the lowest was 322kg / ㎠. However, the 28-day flexural strength of deodorized mortar was much better than that of general cement mortar.
＜표4＞ 실시예 1, 2, 3의 실험결과비교<Table 4> Comparison of Experimental Results of Examples 1, 2, and 3
상기 표에서 알 수 있는 바와 같이 각 실시예에 의한 공시체의 물시멘트비(W/C), 중량감소율, 밀도, 흡수율, 재령 28일 압축강도, 재령 28일 휨강도 등을 비교한 결과, 본 발명 동슬래그를 사용하여 제조한 탈취재료가 종래의 탈취제로 제조한 탈취재료와 탈취제를 사용하지 않은 재료에 비해 물성이 결코 뒤떨어지지 않는 것임을 알 수 있었다.As can be seen from the table, the present invention compares the water cement ratio (W / C), weight reduction rate, density, water absorption rate, compressive strength of 28 days, flexural strength of 28 days, etc. It can be seen that the deodorizing material prepared by using is inferior in physical properties to the deodorizing material prepared using the conventional deodorant and the material which does not use the deodorant.
이처럼 본 발명은 지금까지 별다른 용도가 없이 폐기 매립되어 왔던 동슬래그로 매우 고가인 종래의 탈취소재를 대체하므로써 저렴한 탈취소재를 제조할 수있으며, 또한 환경오염물질인 폐동슬래그를 재활용하여 고부가가치화 하므로써 국가 경제에 이바지함은 물론 공해방지에 매우 유익한 효과를 갖는 것이다.As such, the present invention can manufacture inexpensive deodorant material by replacing the conventionally expensive deodorant material with copper slag that has been disposed of without being used up until now, and also recycles waste copper slag, which is an environmental pollutant, to increase the value of the country. Contributing to the economy as well as having a very beneficial effect on pollution prevention.
