본 발명은 폐자재를 이용한 투수 블록 및 그 제조방법에 관한 것으로서, 특히 도자기, 애자, 타일 및 Si성분을 함유한 도자기 제품을 만드는 과정에서 발생되는 처치 곤란한 폐자재를 이용하여 자원을 재활용할 수 있도록 하며, 소결시 마이크로웨이브파(Microwave)를 이용하여 생산성을 증대시킬 수 있도록 한 폐자재를 이용한 투수 블록 및 그 제조방법에 관한 것이다.The present invention relates to a permeable block using waste materials and a method of manufacturing the same, and in particular, to recycle resources using difficult-to-treat waste materials generated in the process of making ceramic products containing ceramics, insulators, tiles and Si components. In addition, the present invention relates to a permeable block using waste materials and a method for manufacturing the same, which can increase productivity by using microwaves during sintering.

일반적으로 도자기, 애자, 타일 및 Si성분을 함유한 도자기 제품을 만드는 과정에서 발생되는 폐자재 들은 특별한 활용방안이 없기 때문에 그 처치가 매우 곤란한 실정이며, 그대로 방치할 경우 자연환경을 오염시키게 된다.In general, waste materials generated in the process of making ceramic products containing porcelain, insulators, tiles and Si components are very difficult to treat because they do not have special application methods, and if left untreated, they will pollute the natural environment.

한편, 비가 내리게 되면 통상의 녹지는 이중 50%정도는 땅속으로 스며들어 지하수 등으로 활용할 수 있게 되고, 30%정도는 자연증발하고, 10%정도는 수로 등을 통해 강으로 흘러가게 된다.On the other hand, when it rains, about 50% of the greenery can seep into the ground and use it as groundwater, and about 30% of the natural evaporation, and about 10% of it flows into the river through waterways.

그러나 현재 도심의 도로나 보도 등은 대부분 콘크리트 및 아스팔트 등과 같은 불투수성 포장재료에 의해 포장되어 있어 땅속으로 스며드는 비율이 15%정도밖에 되지 않아 집중 호우시에는 하천이나 강의 범람이 우려되고 또한 수자원 부족이 우려되었다.However, most roads and sidewalks in the city are currently paved by impermeable paving materials such as concrete and asphalt, so that only about 15% of the water penetrates into the ground. It became.

따라서 각종 블록이나 콘크리트 등을 투수형으로 제조하는 방안들이 모색되고, 실제로 활용되고 있으나, 대부분 투수형 블록이나 투수형 콘크리트 등의 주재료는 골재나 시멘트 등을 사용함에 따라 재료비가 상승하였으며, 투수 블록의 제조시 원하는 형상으로의 성형 후, 소성을 위해서 통상 오일이나 가스를 이용한 히터 소성로에서 소성을 하므로 소성시간이 오래 걸림에 따라 생산성이 좋지 못하였고 제2의 대기오염의 문제도 앉고 있다.Therefore, various methods of manufacturing various blocks or concrete in permeable form have been sought and are actually used. However, the main material such as permeable block or permeable concrete has increased due to the use of aggregate or cement. After molding to a desired shape during manufacture, since the firing is usually performed in a heater firing furnace using oil or gas for firing, productivity is not good as the firing time is long, and the problem of the second air pollution also sits.

본 발명은 이러한 점을 감안한 것으로, 본 발명은 도자기, 애자, 타일 및 Si성분을 함유한 도자기제품을 만드는 과정에서 발생되는 폐자재를 주재료로 함으로써 폐기물을 재활용할 수 있도록 하며, 바인더로써 발열물질인 페라이트나 티탄산바륨 또는 SiC 또는 철강 슬랙 등을 이용하고 이들 혼합물의 소결시 단시간 내에 고온상승이 가능한 마이크로웨이브파를 이용함으로써 생산성을 증대시킬 수 있도록 한 폐자재를 이용한 투수 블록 및 그 제조방법을 제공함에 그 목적이 있다.The present invention has been made in view of this point, and the present invention allows waste to be recycled by using waste materials generated in the process of making ceramic products containing ceramics, insulators, tiles, and Si components, and is a heating material as a binder. Providing a permeable block using waste materials and a method of manufacturing the same using ferrite, barium titanate, SiC or steel slag, and microwaves capable of increasing the temperature in a short time when sintering these mixtures to increase productivity The purpose is.

도 1은 본 발명의 제조 공정도이다.1 is a manufacturing process chart of the present invention.

이러한 목적을 달성하기 위한 본 발명에 따른 폐자재를 이용한 투수 블록은, 도자기, 애자, 타일 및 Si성분을 함유한 도자기제품을 만드는 과정에서 발생된 폐자재를 수집하여 분쇄한 후 분류하고, 이에 부피단위로 2%∼10%의 전분과 2%∼3%의 페라이트나 티탄산바륨 또는 SiC 또는 철강 슬랙 등의 발열물질을 혼합하여 가압 성형한 후, 오븐에 넣어 2450MHz 또는 915MHz의 마이크로웨이브파를 가하여 1200℃∼1300℃에서 소결시켜 얻어지는 것을 특징으로 한다.Permeable block using the waste material according to the present invention for achieving this object is to collect the waste materials generated in the process of making ceramic products containing porcelain, insulators, tiles and Si components, then crushed and classified, volume Units of 2% to 10% starch and 2% to 3% ferrite, barium titanate, SiC, or steel slag, etc. are mixed and press-molded, and then placed in an oven and subjected to microwave at 2450MHz or 915MHz and subjected to 1200 It is obtained by sintering at C-1300 degreeC.

본 발명에 따른 폐자재를 이용한 투수 블록 제조방법은, 폐자재를 수집하여 분쇄한 후, 분류하는 공정과; 분쇄되어 분류된 폐자재에 부피단위로 2%∼10%의 전분과 2%∼3%의 페라이트 또는 티탄산바륨 또는 SiC 또는 철강 슬랙 등의 발열물질을 혼합하는 공정과; 상기 혼합된 혼합물을 성형틀에 주입하여 가압 성형하는 공정과; 상기 성형된 것을 오븐에 넣어 2450MHz 또는 915MHz의 마이크로웨이브파를 가하여 상기 티탄산바륨이나 페라이트 또는 SiC 또는 철강 슬랙이 1200℃~ 1300℃로 발열하면서 소결시키는 공정을 포함하는 것을 특징으로 한다.Permeable block manufacturing method using the waste material according to the invention, the process of collecting and grinding the waste material, and then sorting; Mixing 2% to 10% starch and 2% to 3% ferrite or barium titanate or SiC or steel slag to a waste material which is ground and sorted by volume; Injecting the mixed mixture into a mold to press-mold; It is characterized in that it comprises a step of sintering the molded product in an oven by applying a microwave wave of 2450MHz or 915MHz, while the barium titanate, ferrite or SiC or steel slack is heated to 1200 ℃ to 1300 ℃.

이하, 첨부한 도면을 참조로 본 발명을 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 폐자재를 이용한 투수 블록의 제조 공정도를 나타낸 것이다.Figure 1 shows a manufacturing process diagram of a permeable block using the waste material according to the present invention.

이에 도시한 바와 같이, 폐자재를 수집하여 분쇄기 등을 이용하여 분쇄한 후, 이를 크기별로 분류하게 된다.As shown in the drawing, the waste materials are collected and pulverized using a grinder or the like, and then classified by size.

분류된 폐자재에 바인더로써 전분(2%∼10% : 부피단위임)과 발열물질인 페라이트(FeO2) 또는 티탄산바륨(BaTiO3) 또는 SiC 또는 철강 슬랙(2%∼3% : 부피단위임)을 첨가하여 혼합한다.Starch (2% to 10%: volume unit) and ferrite (FeO 2 ) or barium titanate (BaTiO 3 ) or SiC or steel slag (2% to 3%: volume unit) ) Is added and mixed.

상기 폐자재에 전분과 티탄산바륨이 혼합된 혼합물 또는 폐자재에 전분과 페라이트 또는 전분과 SiC 또는 전분과 철강 슬랙이 혼합된 혼합물을 성형용 틀에 넣어 가압 성형한다. 성형시 상기 전분에 의해 폐자재와 티탄산바륨 물질(또는 페라이트 또는 SiC 또는 철강 슬랙)이 결합하게 되므로 성형시에는 전분이 바인더의 역할을 하게 된다.The waste material is mixed with a mixture of starch and barium titanate or a mixture of starch and ferrite or starch and SiC or starch and steel slag in the waste material into a mold for pressure molding. The starch serves as a binder during molding because the starch is bonded to the waste material and the barium titanate material (or ferrite or SiC or steel slack) during molding.

성형이 완료되면 성형물을 마이크로웨이브파 오븐에 넣어 마이크로웨이브파를 가하게 된다. 마이크로웨이브파를 가하게 되면 상기 첨가된 발열물질인 페라이트나 티탄산바륨 또는 SiC 또는 철강 슬랙 등의 물질속의 전자들이 운동을 하게 되어 이들의 온도가 상승하게 된다.After the molding is completed, the molded product is placed in a microwave oven to apply microwave waves. When a microwave wave is applied, electrons in a material such as ferrite, barium titanate, SiC, or steel slack, which are the exothermic materials, move, and their temperature increases.

2450MHz 또는 915MHz의 마이크로웨이브파를 가하게 되면 상기 티탄산바륨이나 페라이트는 또는 SiC 또는 철강 슬랙은 1200℃∼ 1300℃로 발열되어 티탄산바륨이나 페라이트 또는 SiC 또는 철강 슬랙이 녹게 된다. 이때, 폐자재나 기타물질(전분)은 마이크로웨이브파에 의해 가열되지 않으므로 티탄산바륨이나 페라이트 또는 SiC 또는 철강 슬랙만이 녹으면서 폐자재 입자와 입자를 붙여주게 된다.When the microwave wave of 2450MHz or 915MHz is applied, the barium titanate or ferrite or SiC or steel slag is heated to 1200 ° C to 1300 ° C to melt barium titanate or ferrite or SiC or steel slag. At this time, the waste materials or other materials (starch) are not heated by the microwave, so barium titanate or ferrite or SiC or steel slag is melted and the waste material particles and particles are attached.

즉, 상기 페라이트나 티탄산바륨 또는 SiC 또는 철강 슬랙을 1200℃∼1300℃로 발열시켜 상기 성형물을 소결시키며, 이후 자연 냉각시켜 투수 블록을 얻게 된다.That is, the ferrite or barium titanate or SiC or steel slag is heated to 1200 ° C to 1300 ° C to sinter the molded product, and then naturally cooled to obtain a permeation block.

이상의 본 발명은 상기 기술된 실시 예에 의해 한정되지 않고, 당업자들에 의해 다양한 변형 및 변경을 가져올 수 있으며, 이는 첨부된 청구항에서 정의되는 본 발명의 취지와 범위에 포함된다.The present invention is not limited to the above described embodiments, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

이상에서 살펴본 바와 같이 본 발명은 폐자재를 이용하여 투수 블록을 만들므로 재료비를 절감할 수 있고, 자원을 재활용할 수 있게 되며, 폐자재에 의한 환경 오염을 방지할 수 있게 된다.As described above, the present invention makes a permeation block using waste materials, thereby reducing material costs, reusing resources, and preventing environmental pollution by waste materials.

또한, 단시간 내에 고온상승이 가능한 마이크로웨이브파를 이용하므로 통상의 오일 또는 가스를 이용한 소성로에서의 소성에 비해 빠른 시간 내에 소결시킬 수 있어 생산성을 향상시킬 수 있게 되며, 마이크로웨이브파를 이용하므로 제2의 대기오염도 방지할 수 있고, 도자기류의 폐자재를 이용하므로 미끄럽지 않고 수명이 긴 장점이 있다.In addition, since the microwave wave that can be elevated in a short time using a microwave can be sintered in a faster time compared to the firing in a kiln using a conventional oil or gas to improve the productivity, and the microwave wave is used as the second Air pollution can also be prevented, and because it uses waste materials of ceramics, it has the advantage of long life without slipping.
