폐유리분말을 이용한 요업용 소지 배합물 및 이의 제조방법 {Potter's clay blend containing glass powder and preparation thereof}Pottery blend using waste glass powder and its manufacturing method {Potter's clay blend containing glass powder and preparation

본 발명은 폐유리 미분말을 포함하는 요업용 소지, 특히 도자기류 제조용 소지 배합물 및 이를 제조방법에 관한 것으로, 더욱 자세하게는, 폐유리를 조분쇄한 후, 이를 더욱 미세하게 분쇄하여 폐유리 미분말을 각종 요업 소지용 원료에 배합하여 제조한 요업용 소지 및 이의 제조방법에 관한 것이다.The present invention relates to a ceramic material containing waste glass fine powder, in particular, a blend for producing ceramics, and a method for manufacturing the same. More specifically, after coarse grinding waste glass, finely pulverizing the fine waste glass powder, The present invention relates to a ceramic base material prepared by mixing with a ceramic base material and a manufacturing method thereof.

유리는 요업제품 중의 하나로서, 뛰어난 장식성 및 투명성 등과 같은 특성을 가지고 있어, 건축자재, 자동차공업 뿐만 아니라 전자 및 전기공업에 널리 사용되고 있다. 그러나, 다른 요업 제품과 마찬가지로 이들은 산업 및 생활 전반에 걸쳐 기초 소재 또는 물품으로서 널리 사용되나, 이들의 파손 또는 교체 후의 폐기의 어려움으로 인해 추가비용발생 및 환경오염 등과 같은 문제점을 일으키고 있다.Glass is one of ceramic products and has characteristics such as excellent decoration and transparency, and is widely used in electronic materials and electrical industries as well as building materials and automobile industry. However, like other ceramic products, they are widely used as basic materials or articles throughout industry and life, but due to the difficulty of disposal after their breakage or replacement, they cause problems such as additional costs and environmental pollution.

폐유리 등의 처리 방법으로는, 제품 자체로서의 재활용, 유리공장에서 원료로서의 재활용, 또는 매립 등이 현재 사용되고 있다. 이중 재활용 처리법이 환경문제를 유발하지 않는다는 이유로 권장되고 있으나, 제품 자체로서의 재활용은 수집 및 세척 시에 위생 및 경제적인 문제가 여전히 남아있어 제한적이며, 유리공장에서 원료로서의 재활용도 마찬가지로 수집 및 세척, 그리고 유리제품 제조시에 들어간 추가 성분들의 제거에 추가비용이 들어가며, 이를 방지하기 위해 폐유리를 유리 제품별로 분류하는 것도 어려워 널리 사용되지 못하고 있다. 이러한 실정에서, 대부분의 폐유리의 처리는 경제적으로 불리하고 환경오염을 유발하는 매립에 거의 의존하고 있다.As a treatment method of waste glass or the like, recycling as a product itself, recycling as a raw material in a glass factory, or landfilling are currently used. Although the dual recycling method is recommended because it does not cause environmental problems, recycling as the product itself is limited due to hygiene and economic problems still remaining during collection and cleaning, and recycling as raw materials in glass factories is also collected and washed, and There is an additional cost for the removal of additional components in the manufacture of glass products, and in order to prevent them, it is difficult to classify waste glass by glass products and thus it is not widely used. In this situation, most waste glass treatments are economically disadvantageous and rely almost entirely on landfills that cause environmental pollution.

일반적으로 요업제품들은 점토, 규석 및 장석을 주성분으로 하는 삼축계 성분 소지를 원료로 하며, 이들 점토, 규석 및 장석은 규산염을 주성분으로 한다. 요업 제품 중의 하나인 유리의 화학적 조성은, 판유리 및 병유리를 기준으로 할 때 SiO2약 70∼74%, Na2O 약 14∼15%, CaO+MgO 약 7∼14%로 구성되어 있고, 그외 Al2O3및 Fe2O3를 미량 함유한다. 이러한 요업 제품들은, 제품 유형에 따라 조성비, 첨가 성분, 및 소성온도 등의 제조과정이 차이가 있으나, 요업 제품 제조용 소지들은 실질적으로 동일한 원료들을 필요에 따라 적절한 조성을 가지도록 배합되었기에, 전체적인 조성은 유사하다.In general, ceramic products are based on triaxial components containing clay, silica and feldspar as main ingredients, and these clays, silica and feldspar are mainly silicate. The chemical composition of glass, which is one of the ceramic products, is composed of about 70 to 74% of SiO 2, about 14 to 15% of Na 2 O, and about 7 to 14% of CaO + MgO, based on plate glass and bottle glass. Other contains Al 2 O 3 and Fe 2 O 3 trace. These ceramic products have different manufacturing processes, such as composition ratio, additives, and firing temperature, depending on the type of product. However, the materials for manufacturing ceramic products are substantially the same raw materials are formulated to have an appropriate composition as needed, so the overall composition is similar. Do.

따라서, 본 발명자들은, 이러한 산업 및 생활 현장에서 발생하는 폐유리를 환경오염이나 추가적인 비용을 거의 발생시키지 않고 처리하는 것에 대해 연구하는 도중, 유리가 다른 요업제품과 실질적으로 동일한 원료로부터 제조되며, 화학적 조성도 유사한 것에 착안하여, 폐유리를 미분쇄하여 다른 요업 제품 제조용 소지에 첨가할 수 있는가에 대해 연구하였다. 그 결과, 폐유리 미분말을 포함하는 혼합소지로부터 요업 제품을 제조할 때 기존의 소지만을 사용하는 요업 제품을 제조할 때보다 여러 가지 이점이 있고, 제조된 제품도 동등하거나 우수한 성질을 나타냄을 알아내었다.Thus, the inventors of the present invention, while studying the treatment of such waste glass from industrial and living sites with little environmental pollution or additional costs, are made of glass from substantially the same raw materials as other ceramic products, Focusing on the similar composition, it was investigated whether waste glass can be pulverized and added to other ceramic products. As a result, it has been found that manufacturing ceramic products from mixed substrates containing waste glass fine powder has many advantages over the manufacture of ceramic products using only small pieces, and the manufactured products have the same or superior properties. .

따라서, 본 발명의 목적은, 폐유리를 분쇄하여 만들어진 미분말을 포함하는 요업용 소지 배합물을 제공하는 것이다.It is therefore an object of the present invention to provide a ceramic base blend comprising fine powder made by grinding waste glass.

본 발명의 또다른 목적은, 이렇게 제조된, 폐유리 분말을 포함하는 요업용 소지 배합물을 사용하여 요업제품을 제조하는 방법을 제공하는 것이다.It is a further object of the present invention to provide a method for producing a ceramic product using the ceramic base formulation comprising the waste glass powder thus prepared.

본 발명에 있어서, 폐유리 미분말이란 폐유리로부터 제조된 미분말을 포함하여 본원발명의 목적을 달성할 수 있는 모든 유리의 미분말을 의미한다.In the present invention, the waste glass fine powder means a fine powder of all glass which can achieve the object of the present invention, including fine powder prepared from waste glass.

본 발명에서 있어서, 요업용 소지란, 요업제품을 제조하기 위해 사용되는 원료 및 이들의 혼합물을 포괄하여 의미한다.In the present invention, the base material for ceramics encompasses the raw materials and mixtures thereof used for producing the ceramic products.

본 발명의 또다른 목적 및 이점은 하기로부터 더욱 명백히 알 수 있을 것이다.Still other objects and advantages of the present invention will become more apparent from the following.

폐유리는 산업 및 생활 현장에서, 많이 생겨나고 있다. 유리 제품에 따라 화학적 조성이 조금씩 차이가 나지만, 본 발명에 따르면, 이러한 유리의 종류는 크게 중요하지 않다. 그러나 대량 수거가 용이하고 비교적 일정한 조성을 갖는 폐유리를 사용하는 것이 바람직하며, 무색 또는 무색에 가까운 폐유리를 이용하는 것이 더욱 바람직하다.Waste glass is emerging a lot in industrial and living fields. Although the chemical composition varies slightly depending on the glass product, according to the present invention, the kind of such glass is not very important. However, it is preferable to use waste glass which is easy to collect in a large quantity and has a relatively constant composition, and more preferably, colorless or near colorless waste glass.

현재 자동차 수리소 등에서 발생되는 자동차용 폐유리는 수거비를 지출해야 하는 등 처리에 곤란을 겪고 있을 뿐만 아니라, 다량이면서 비교적 일정한 조성의 폐유리를 수거하는 것이 용이하므로, 본 발명에서는 자동차용 유리를 주재료로써 사용하고 이를 중심으로 본 발명을 설명하지만, 본 발명이 이것으로 한정되지 않는다는 점은 명백하다.At present, the waste glass for automobiles generated at an automobile repair shop is not only having difficulty in processing such as having to pay a collection fee, but also easily collects a large amount of waste glass having a relatively constant composition. Although the present invention will be described using and focusing on it, it is obvious that the present invention is not limited thereto.

수거된 폐유리는 1차적으로 로울러 타잎의 조분쇄기 또는 파쇄기를 이용하여 조분쇄된 후, 2차적으로 볼밀, 팬밀 등을 사용하여 원하는 크기로 미분쇄된다. 1차로 조분쇄된 폐유리의 크기는 제한되지 않지만, 2차적으로 미분쇄할 때 사용하는 볼밀, 팬밀 등에 사용하기에 적절한 크기가 바람직하다. 2차 미분쇄물의 입도는 일반적으로 요업용 소지의 입자 크기에 따라 결정되며, 바람직하게는 60 ∼ 650 메쉬, 더욱 바람직하게는 120 ∼ 325 메쉬의 크기를 갖도록 조절한다.The collected waste glass is primarily pulverized using a roller mill or crusher, and then secondly pulverized to a desired size using a ball mill, a pan mill, or the like. Although the size of the primary coarsely ground waste glass is not limited, a size suitable for use in ball mills, pan mills, and the like used in the second milling is preferable. The particle size of the secondary pulverized product is generally determined according to the particle size of the ceramic substrate, and is preferably adjusted to have a size of 60 to 650 mesh, more preferably 120 to 325 mesh.

폐유리 미분말의 입도가 650 메쉬보다 적은 경우에는, 본 발명의 목적 달성에 어려움이 있는 것은 아니지만, 이렇게 미세 분쇄에 추가의 노력이 요구되기 때문에 경제적으로 불리하다.If the particle size of the waste glass fine powder is less than 650 mesh, there is no difficulty in achieving the object of the present invention, but it is economically disadvantageous because additional efforts are required for fine grinding.

폐유리 미분말의 입도가 120 메쉬 이상인 경우에도, 본 발명의 목적 달성에 어려움이 있는 것은 아니지만, 원료 소지와의 배합에 어려움이 있고, 소성온도의 저하효과가 감소된다.Even when the particle size of the waste glass fine powder is 120 mesh or more, it is not difficult to achieve the object of the present invention, but it is difficult to mix with the raw material material, and the effect of lowering the firing temperature is reduced.

상기 입도보다 큰 폐유리 분말을 소지 원료 성분들과 배합한 다음 분쇄하여 혼합할 수도 있다.Waste glass powder larger than the particle size may be combined with the raw material ingredients and then ground and mixed.

폐유리 미분말의 적절한 입도는 배합시킬 소지의 입도와 유사한 것이 유리하며, 따라서 폐유리 미분말을 선별하여 사용할 수도 있다.The appropriate particle size of the waste glass fine powder is advantageously similar to that of the base to be blended, and thus, the waste glass fine powder may be selected and used.

이렇게 제조된 폐유리 미분말을 포함하는 소지 배합물을 사용하여 여러 가지 요업 제품을 성형하고, 건조하고, 소성한다. 경우에 따라 두벌구이를 할 수도 있다.Various blends of ceramic products are molded, dried, and calcined using the base blend comprising the waste glass fine powder thus prepared. In some cases, you can roast two.

일반적으로, 요업 제품의 소성온도는 제품의 유형에 따라 다소 차이가 있지만, 일반적으로 도기의 경우 1,100 ∼ 1,200℃, 자기의 경우 초벌구이와 두벌구이가 1200 ∼ 1300 ℃, 건축용 타일의 경우 1250℃, 그리고 경질 자기의 경우 600 ∼ 800℃ (초벌구이) 및 1350 ∼ 1450℃ (두벌구이) 및 연질자기의 경우 1250 ∼ 1300 ℃ (초벌구이) 및 900 ∼ 1100℃ (두벌구이)이다.In general, the firing temperature of ceramic products varies somewhat depending on the type of product, but generally 1,100 to 1,200 ° C for pottery, 1200 to 1300 ° C for roasting and bulbeul for porcelain, 1250 ° C for building tiles, and In the case of hard porcelain, it is 600-800 degreeC (first roasting) and 1350-1450 degreeC (dual roasting), and in the case of soft magnetism, 1250-1300 degreeC (first roasting) and 900-1100 degreeC (two roasting).

본 발명자들은, 또한 놀랍게도, 본 발명에 따른 소지 배합물을 사용하여 도자기 등의 요업 제품을 제조할 때, 1100∼1300℃에 달하는 도자기의 소성 온도를 1000 ∼ 1,100℃로 낮출 수 있음을 발견하였다.The inventors also surprisingly found that when producing ceramic products such as porcelain using the base blend according to the present invention, the firing temperature of porcelains ranging from 1100 to 1300 ° C can be lowered to 1000 to 1,100 ° C.

이러한 현상은, 유리 공업에서 유리 제조용 소지로서 파유리를 첨가할때 가공온도를 저하시킴으로써 소요되는 에너지의 절감효과를 얻을 수 있는 것과 유사한 효과이지만, 무정질의 유리 제조시에 동일한 파유리를 첨가할 때의 가공온도 저하효과가, 유리와는 동일 원료계이지만 그 물성이 상이한 도자기류의 소성시에도 유리분말을 첨가함으로써 가공온도 저하효과가 나타난다는 것은 놀라운 일이다. 이러한 소성온도 저하에 따른 에너지 절감 효과는, 본 발명에서 예측하지 못한 또다른 탁월한 효과이다.This phenomenon is similar to the effect of reducing the energy required by lowering the processing temperature when adding cullet as a glass making material in the glass industry, but when adding the same cullet in the production of amorphous glass It is surprising that the effect of lowering the processing temperature is that the effect of lowering the processing temperature is obtained by adding glass powder even when firing ceramics having the same raw material as glass but having different physical properties. The energy saving effect due to the lowering of the firing temperature is another excellent effect not predicted in the present invention.

이하에, 본 발명의 폐유리 미분말을 포함하는 요업용 소지 배합물을 요업제품의 제조에 이용하는 것에 대해 기술한다.Below, it describes about using the ceramics base material formulation containing the waste glass fine powder of this invention for manufacture of a ceramics product.

도기 및 자기질 요업물의 제조에 주로 많이 사용되는 고령토(kaoline), 점토(clay), 백토이며, 이들을 혼합하여 특수 유형 또는 특정 유형의 도자기류의 제조에 적합화된 원료 소지도 시판되고 있다.Kaolin, clay, and clay, which are mainly used for the production of ceramics and porcelain ceramics, are also commercially available.

이들 도자기류 요업물의 제조용 원료 소지에, 본 발명에 따른 폐유리 미분말(입도 약 325 메쉬)을 약 20 ∼ 40 중량%의 양으로 혼합하여 소지 배합물을 제조하였다.A raw material blend was prepared by mixing the waste glass fine powder (particle size of about 325 mesh) according to the present invention with the raw material for preparing ceramics ceramics in an amount of about 20 to 40% by weight.

이렇게 제조된 소지 배합물을 사용하여 기존의 도자기류 제조방법에 따라 도자기류를 제조할 경우, 성형 건조시에 균열이 방지되고 소성 강도가 증대됨을 실험을 통해 확인할 수 있었다.When the porcelains were manufactured according to the existing porcelains manufacturing method using the thus prepared blend, it was confirmed through experiments that cracks were prevented and plastic strength was increased during molding drying.

이렇게 성형 건조된 도자기를 1000 ∼ 1,100℃의 낮은 온도에서 소성하지만, 사용한 소지의 조성 및/또는 목적하는 물품 (즉 도기 또는 자기) 유형 및 강도, 추후 공정을 위해 더욱 고온 또는 저온에서 성형할 수도 있다.The molded and dried ceramics are then fired at low temperatures of 1000 to 1,100 ° C., but may also be molded at higher or lower temperatures for the composition of the substrate used and / or the type and strength of the desired article (ie pottery or porcelain) and for further processing. .

본 발명에 따른 소지 배합물을 사용하여 제조된 도자기류는 유리 미분말을 포함하지 않는 소지를 사용하여 제조된 도자기류와 외관상 차이가 없었으며, 강도등의 물성에 있어서도 거의 차이가 없었다.Porcelain prepared using the base material blend according to the present invention was no difference in appearance from the porcelain produced using a glass containing no fine powder, there was almost no difference in physical properties such as strength.

이외에도, 본 발명에 따른 요업용 소지 배합물을 사용하여 다른 요업 제품의 제조에도 유리하게 사용할 수 있다.In addition, it can be advantageously used for the production of other ceramic products using the ceramic base formulation according to the present invention.
