Abstract

본 발명은 패각을 분쇄하여 분말로 만든 후 적절한 바인더 및 발포제를 혼합하여 일정 틀 속에서 열을 가하여 팽창시킨 뒤 충분히 굳게 만들어 흡음 및 차음효과까지 지닌 무기 보온단열재를 제조하는 폐패각을 이용한 무기보온단열재 제조방법에 관한 것으로써, 현재 우리나라 연안선을 따라 다량으로 발생되고 있지만 처리가 곤란하여 환경에 피해를 입히고 있는 패각을 이용함으로써 자연환경보호에도 일익을 담당할 수 있을 뿐만 아니라 기존의 보온단열재를 대체함에 따라 유용한 자원의 절감을 기할 수 있으며, 특히 유기 보온단열재인 EPS나 폴리우레탄에 비하여 연소되지 않는 점은 물론 화재 시에도 각종 유해물질이 발생하지 않아 대형 인명피해의 방지에 도움이 될 수 있다.The present invention is an inorganic heat insulating material using a waste shell to produce an inorganic heat insulating material having a sound absorption and sound insulation effect by swelling the shell after making a powder by mixing the appropriate binder and foaming agent to expand the heat in a certain frame and then swelling sufficiently. It is related to the manufacturing method. Currently, it is generated in large quantities along Korea's coastline, but it is difficult to process, so it is not only able to play a part in protecting the natural environment, but also replaces existing thermal insulation materials by using shells that are damaging the environment. As a result, it is possible to reduce useful resources, and in particular, it does not burn compared to EPS or polyurethane, which is an organic thermal insulation material, and may also help to prevent large-scale casualties since various harmful substances do not occur in a fire.

우리나라의 연안, 특히 남해안에는 굴, 고막 그리고 바지락 같은 각종 패류를 양식하고 있어 어촌 소득 향상에 크게 기여하고 있다. On the coast of Korea, especially the south coast, various shellfish such as oysters, eardrums, and clams are farmed, contributing to the improvement of fishing village income.

그러나 이들 양식업에는 패류를 가공한 후 버려지는 폐패각이 매우 많으나 제대로 처리 및 재활용되지 못한 채 박신장 같은 가공공장 근처에 버려져 있어 주변의 환경오염을 심각하게 가중시키고 있는 실정이다. <표 1>은 우리나라에서 패류 의 종류별 생산량을 나타내고 있다.However, these aquaculture industries have a lot of waste shells discarded after processing shellfish, but they are being disposed near processing plants such as Park Shin-jang without being properly processed and recycled, which seriously aggravates environmental pollution. <Table 1> shows the production of shellfish in Korea.

폐패각은 오랫동안 수하양식된 패류의 껍질이므로 그 조직 속에는 염분 같은 바닷물 성분이 제법 함유되어 있다. Lung shells are shells of shellfish that have been cultivated for a long time, and their tissues contain saltwater components such as salt.

따라서, 이러한 폐패각은 농업용은 물론 기타 용도로도 바로 사용되어지기 어렵다. Therefore, these closed shells are difficult to be used immediately for agricultural and other purposes.

특히, 고온처리가 되지 않고 압축만 하여 제조되는 건자재용으로 사용될 경우에는 가공 후 염분이나 바닷물 성분에 의해 곰팡이가 제품에서 심각하게 번식하게 되므로 노천에서 약 2~3년의 방치가 필요하다. In particular, when used for construction materials that are manufactured by compression only without high temperature treatment, molds are seriously multiplied by the salt or seawater components after processing, so they need to be left in the open air for about two to three years.

최근 정부의 주도 아래 많은 예산을 투입하여 폐패각을 이용한 칼슘공장 및 비료공장 등이 건설되고 있으나 아직까지 처리량이나 처리효율적인 면에 있어서 문제가 모두 해결된 것은 아니므로 이의 적절한 처리를 위한 새로운 해결방안이 시급한 실정이다.Recently, a calcium plant and a fertilizer plant using waste shells have been built under the government's guidance, but not all problems have been solved in terms of throughput and treatment efficiency, so a new solution for proper treatment is needed. It is urgent.

참고로 지금까지는 막대한 양의 폐패각을 비료용, 채묘용, 김포자용 등으로 처리하고 나머지는 매립시키거나 방치하고 있다.For reference, until now, a huge amount of waste shells have been treated with fertilizer, chaebol, gimpoja, etc., and the rest is reclaimed or left unattended.

단지, 최근에 들어 산성비 중화, 적조 제어, 인 제거 등이나 수질 정화에 폐패각이 활용되기 시작하였으며 일부이기는 하나 콘크리트 원료, 도로 기층재에서부터 기능성 건축 내장재로 활용하는 사례가 보고되고 있으나 그 양이 미미할 뿐만 아니라 모두 압축시켜 밀집형 건자재를 제조하는 것에 그치고 있다.Recently, waste shells have been used to neutralize acid rain, control red tide, remove phosphorus, or purify water quality, although some cases have been reported to be used as functional building interior materials from concrete raw materials and road foundations. In addition, they are all compressed to produce dense building materials.

상기의 문제점을 해결하기 위해 안출된 본 발명의 목적은, 폐패각 분말을 팽창시켜 그 내부에 형성된 기포에 의한 보온단열효과를 향상시킬 뿐만 아니라 경량화를 이루어 보온단열을 위한 샌드위치판넬 등의 내부 충진재는 물론 흡음 및 차음이 요구되는 전동차 내부 구조 충진재 등의 각종 건자재에 다양하고 유용하게 사용할 수 있는 무기보온단열재를 제조하는 방법을 제공하는 데에 있다.An object of the present invention devised to solve the above problems is to expand the waste shell powder to improve the thermal insulation effect by the bubbles formed therein, as well as to reduce the weight of the internal fillers such as sandwich panels for thermal insulation Of course, the present invention provides a method for manufacturing an inorganic thermal insulation material that can be used in various and useful materials such as electric vehicle internal structure fillers that require sound absorption and sound insulation.

본 발명의 또 다른 목적은, 연속적으로 공급되는 분쇄된 폐패각의 분말에 발포제, 분산제, 바인더를 혼합할 수 있는 혼합장치를 제공하는 데에 있다.Still another object of the present invention is to provide a mixing apparatus capable of mixing a blowing agent, a dispersant, and a binder with a powder of pulverized waste shell supplied continuously.

도 1은 본 발명에 따른 무기보온단열재 제조방법의 흐름도이다.1 is a flowchart of a method of manufacturing an inorganic thermal insulation material according to the present invention.

먼저 전처리단계(S110)에서는 폐패각으로부터 염분 같은 바닷물 성분을 빠져 나가게 하거나 파쇄와 같은 간단한 방법으로 표면에 붙은 조대 이물질과 너절한 부분을 제거한다.First, in the pre-treatment step (S110) to remove the saltwater components such as salinity from the waste shell or remove the coarse foreign matter and sloppy parts attached to the surface by a simple method such as crushing.

본 발명의 무기보온단열재 제조방법에서 하기(下記)의 성형공정이 고온에서 이루어지므로 곰팡이의 서식 같은 부작용이 없어서 본 발명에서 사용되는 폐패각은 장시간 노천에서 방치할 필요는 없으나 가능한 오래 방치된 폐패각을 이용하면 더 유리하다.Since the following molding process is performed at a high temperature in the method of manufacturing an inorganic thermal insulation material of the present invention, there is no side effect such as mold formation, so the waste shell used in the present invention does not need to be left in the open air for a long time, but it is left as long as possible. It is more advantageous to use.

폐패각은 우선 조대이물질이나 나일론 줄 같은 것은 물론이거니와 단단한 껍질 위에 붙어 있는 너절한 부위를 제거하는 것이 좋다. Lung shells, as well as coarse foreign objects or nylon strings, as well as remove the sloppy areas on the hard shell is good.

왜냐하면 이 너절한 부위에 염분 등이 많이 함유되어 있어 제품에 포함될 경우 품위를 저하시키기 때문이다. 이 너절한 부위는 1차파쇄만 하여도 다른 부위와는 달리 쉽게 미분화되므로 스크린 등을 통하여 걸려주면 쉽게 분리가 가능하다. 그 이후에는 풍력선별이나 수선별로 조대 이물질이나 나이론 등을 분리시킨다.Because it contains a lot of salt, etc. in this sloppy area, if included in the product will degrade the quality. This sloppy part is easily micronized unlike other parts only by primary crushing, so it can be easily separated by hanging through a screen. After that, it separates the coarse foreign material and the nylon by wind screening and repair.

폐패각의 종류에 따른 완성품의 성상은 크게 차이가 나지 않으나 우리나라에서 가장 많이 발생되고 있는 굴 폐패각의 경우, 다른 패각에 비해 분말화 이후 강도가 다소 떨어진다. The properties of the finished products according to the types of waste shells are not significantly different, but the strength of the oyster waste shells, which is the most frequently generated in Korea, is somewhat lower after powdering than other shells.

그러나 팽창에 의한 보온단열재로 제조할 경우는 충분히 좋은 제품을 제조할 수 있다. 물론 가리비나 꼬막류 폐패각 등을 어느 정도 혼입하면 더 좋은 물성의 제품을 기대할 수가 있다.However, in the case of manufacturing the thermal insulation by the expansion can be produced a sufficiently good product. Of course, if you mix the scallops and shells of shellfish to some extent, you can expect a better product.

그리고, 다음으로 분쇄단계(S120)에서는 상기 전처리단계(S10)에서 얻어진 주원료인 폐패각을 그라인더를 사용하여 작은입자 또는 미세분말로 만든다.Then, in the grinding step (S120), the waste shell, which is the main raw material obtained in the pretreatment step (S10), is made into small particles or fine powder using a grinder.

폐패각은 무기질 중에서는 경도가 비교적 약하고 딱딱한 성질을 갖고 있으므로 분쇄하는 것은 비교적 쉬운 공정에 속한다. Waste shells are relatively weak in hardness and hard in minerals, so grinding is a relatively easy process.

그러나 한 번에 50~250 mesh의 입자를 갖도록 분말화 시키기는 어려움이 있으므로 일단 파쇄기(shredder)로 파쇄하여 너절한 부위를 분말화시켜 제거한 후, 볼밀 또는 햄머 타입의 분쇄기를 수회(예를 들어, 2회) 반복하여 거치면 나머지 부위도 250 mesh 정도의 분말로 쉽게 얻을 수 있다. 입자의 크기는 요구되는 제품의 발포 정도, 강도 등에 따라 조절한다.However, it is difficult to powder to have particles of 50 to 250 mesh at a time, so once shredder is crushed to remove the crushed parts, the ball mill or hammer type grinder is several times (for example, 2 Times) If you go through it repeatedly, the remaining part can be easily obtained as powder of about 250 mesh. The size of the particles is adjusted according to the degree of foaming, strength, etc. of the product required.

다음의 혼합단계(S130)에서는 이러한 분쇄단계(S120)를 연속적으로 실시하면서 공급되는 상기 미세분말을 교반기능을 갖춘 밀폐형 반응기에서 빠르게 교반하면서 발포제와 분산제를 주입하여 혼합하여 중간원료를 만들고, 다시 상기 중간원료에 바인더를 더 혼합하여 최종원료를 만든다.In the next mixing step (S130), while feeding the fine powder supplied continuously while performing the grinding step (S120) in a closed reactor equipped with a stirring function while injecting a blowing agent and a dispersant to make an intermediate raw material, again The final raw material is made by further mixing the binder with the intermediate raw material.

처음부터 바인더를 섞으면 성형공정 이전에 굳어지기 때문에 이를 제외한 다른 분말 형태의 원료들을 우선 혼합시킬 필요가 있다. Since the binder is hardened before the molding process from the beginning, it is necessary to first mix the other raw materials in powder form.

따라서 밀폐된 이중바닥 교반형 반응기 내에서 가능하면 짧은 시간에 폐패각 분말과 부원료가 골고루 섞이게 하여야 한다.Therefore, in the closed double bottom stirred type reactor, the waste shell powder and the subsidiary materials should be evenly mixed in the shortest possible time.

팽창을 위한 발포제는 이산화질소를 방출하는 ADCA(azo di-carbide amide)를 사용하며 발포비율이나 완성품의 강도 등을 감안하여 중량비로 약 3~20%를 투입한다. 그리고 분산 촉진을 위해 실리콘계 계면활성제를 0.2~2% 정도 첨가한다.Foaming agent for expansion uses azo di-carbide amide (ADCA) which releases nitrogen dioxide, and injects about 3 to 20% by weight in consideration of the foaming ratio and the strength of the finished product. And 0.2 to 2% of the silicone surfactant is added to promote the dispersion.

그리고, 상기 중간원료에 공급되는 바인더는 역시 상품의 강도나 용도를 감안하여 중량비로 5~15% 범위에서 투입한다.In addition, the binder supplied to the intermediate raw material is also added in the range of 5 to 15% by weight in consideration of the strength or use of the product.

상기 바인더는 분말 입자 간 결합을 위한 액체 바인더로 분자량 900~1100의 비닐에스테르(vinyl ester)계 수지를 주입하면서 급속 교반기에서 완전 혼합되어 즉시에 성형공정으로 자동 주입되도록 한다.The binder is a liquid binder for bonding between powder particles, and is completely mixed in a rapid stirrer while injecting a vinyl ester resin having a molecular weight of 900 to 1100 to be automatically injected into a molding process immediately.

주원료인 폐패각 분말과 바인더를 제외한 다른 첨가제들은 모두 반응기의 상부에 위치한 호퍼 및 주입구들을 통하여 정량공급 되어진다.All other additives, except the main shell waste powder and binder, are metered through the hopper and inlet located at the top of the reactor.

그리고, 성형단계(S140)에서 상기 혼합단계(S130)에서 공급된 최종원료를 성형틀에 주입하고, 외부에서 열을 공급하여 최종적으로 무기보온단열재를 제작한다.Then, the final raw material supplied in the mixing step (S130) in the molding step (S140) is injected into the mold, and finally supplying heat from the outside to produce an inorganic thermal insulation.

상기 형틀에 주입하는 것은 상기 최종원료를 소정의 양만큼 일정하게 성형하고자 하는 틀의 바닥면에 골고루 그리고 일정량의 두께로 자동으로 주입하여 준다.Injecting the mold is automatically injected evenly and a certain amount of thickness on the bottom surface of the mold to be uniformly molded by the predetermined amount of the final raw material.

예를 들어, 샌드위치판넬 같은 경우, 그 길이를 따라 골고루 하판에 비로 쓸듯이 뿌려주고 상판을 덮지만, 타일이나 작은 판상 모양의 제품을 얻으려고 하는 경우는, 그 제품 형태의 틀에 일정량의 중간원료를 골고루 주입시킨 후 원료의 팽창압을 견딜 정도의 무게 또는 장치가 된 뚜껑을 덮는다. For example, in the case of a sandwich panel, evenly spraying the lower plate evenly along its length and covering the top plate, but in order to obtain a tile or a small plate-shaped product, a certain amount of intermediate raw material in the form of the product After evenly injected, cover the lid with the weight or device enough to withstand the expansion pressure of the raw material.

또한, 냉장고 같은 일정 장치의 내부를 충진 시키고자 할 경우는 노즐 등에 의해서 일정량을 주입(injection)시키는 방법을 택한다.In order to fill the inside of a certain device such as a refrigerator, a method of injecting a certain amount by a nozzle or the like is selected.

상기 성형을 위하여 형틀의 온도를 상기 최종원료에서 충분히 발포가 일어날 수 있을 정도의 온도인 240~270oC로 급속히 상승시키는 것이 중요하다.It is important for the molding to rapidly increase the temperature of the mold to 240 ~ 270 ° C, which is a temperature enough to cause foaming in the final raw material.

왜냐하면 같이 혼입된 바인더가 굳어지기 전에 희망했던 부피로 팽창되는 것이 필요하기 때문이다.This is because the binders incorporated together need to be expanded to the desired volume before they harden.

특히, 오븐 내의 온도는 소정의 온도가 도달되었다 하더라도 단열재의 재질이 담긴 틀 내부의 온도가 충분하지 못할 수 있으므로 오븐 온도와 실제 원료의 온도의 상관관계를 파악하여 두었다가 적용하는 것이 필요하다.In particular, the temperature in the oven, even if a predetermined temperature is reached, the temperature inside the frame containing the material of the insulating material may not be sufficient, it is necessary to find and apply the correlation between the oven temperature and the actual raw material temperature.

이렇게 온도를 높게 유지한 이후에는 바인더에의 의한 충분한 결합과 굳는데 필요한 시간이 필요하게 된다.After maintaining this high temperature, the time required for sufficient bonding and hardening by the binder is required.

이 가류(curing)에 필요한 시간은 길면 길수록 유리하지만 약 5시간 정도이면 충분하다.The longer the time required for this curing, the longer the advantage, but about 5 hours is sufficient.

다만 급속한 냉각은 경우에 따라 제품이 휘어지는 경우도 있을 수 있으므로 서냉시키는 것이 바람직하다.However, rapid cooling may cause the product to bend in some cases, so slow cooling is desirable.

다음으로 상기 혼합단계(S130)를 실현하기 위한 혼합장치를 설명한다.Next, a mixing apparatus for realizing the mixing step S130 will be described.

상기 혼합장치의 작동모습을 상세히 설명한다.The operation of the mixing device will be described in detail.

먼저 상기 주원료호퍼(101)에 도시되지 않은 분쇄장치로부터 분쇄된 폐패각 미세분말이 연속적으로 공급되고, 상기 부원료투입구(102,103,104)에 부원료인 발포제 및 분산제가 공급된다.First, the waste shell fine powder pulverized from a pulverizer not shown in the main raw material hopper 101 is continuously supplied, and a blowing agent and a dispersant as auxiliary materials are supplied to the sub raw material inlets 102, 103 and 104.

그리고, 이러한 주원료와 부원료가 상기 혼합기(130)에 의해 혼합되어 중간원료가 형성되고, 이 때 상기 중간게이트(140)는 닫힌 상태이다.In addition, the main raw material and the sub raw material are mixed by the mixer 130 to form an intermediate raw material, and the intermediate gate 140 is in a closed state.

따라서, 도 3과 같은 보온단열재를 만들 수 있다.Therefore, it is possible to make a heat insulating material as shown in FIG.

상기와 같이, 본 발명의 바람직한 실시예를 참조하여 설명하였지만 해당 기술 분야의 숙련된 당업자라면 하기의 특허청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다. As described above, it has been described with reference to the preferred embodiment of the present invention, but those skilled in the art various modifications and changes of the present invention without departing from the spirit and scope of the present invention described in the claims below I can understand that you can.

본 발명을 이용하여 폐패각으로부터 무기 보온단열재를 생산하면 어촌에서 한 해 약 32여만톤씩 발생되어 계속 적체되고 있는 폐패각을 적절하고 대량으로 처리할 수 있어 우선 연안선 환경개선에 크게 이바지할 수 있다.When the inorganic thermal insulation material is produced from the waste shell using the present invention, about 320,000 tons per year are generated in the fishing village, and the waste shell that is continuously accumulated can be properly and largely processed, which can greatly contribute to the improvement of the coastline environment. have.

또한 버려지는 폐기물로부터 유용한 건자재 등을 생산함으로써 그동안 막대한 외화를 지불하고 수입에 의존하여 생산하던 각종 보온단열재의 원료를 국내에서 거의 무상으로 조달할 수 있으므로 외화의 절약은 물론 유용한 자원의 절약을 기할 수 있다. 특히 채굴 가능한 부존 석유자원이 2038년에는 고갈될 것이라는 보고가 있음을 감안하면 석유자원의 절약은 물론 석유 고갈 이후의 원료를 미리 발굴하여 두는 것도 의미가 크다고 하겠다.In addition, by producing useful construction materials from the waste that is discarded, it is possible to procure huge amounts of foreign currency and raw materials of various thermal insulation materials produced in dependence on imports for free at home, thus saving foreign currency and saving useful resources. have. In particular, considering that there are reports that the minable oil resources will be exhausted by 2038, it is significant to not only save oil resources but also to find raw materials after oil exhaustion.

그리고 일반 폐패각가 압축성형으로 이루어져서 비교적 비중이 높은데 반하여 본 발명에 의한 폐패각 보온단열재는 발포시켜 최대 50배까지 팽창되어지므로 보온성이 높을 뿐만 아니라 흡음 및 차음효과도 뛰어나며 비중이 아주 낮아 중간충진재로 다양하게 이용이 가능하다. 일예로 아파트의 층간 또는 세대간 보온 및 소음차단재로도 효과가 크다.In addition, since the general closed shell is made of compression molding and relatively high in specific gravity, the closed shell thermal insulation material according to the present invention is expanded by up to 50 times by foaming, so that the thermal insulation is not only high, but also excellent in sound absorption and sound insulation, and its specific gravity is very low. It is possible to use. For example, it is also effective as insulation and noise blocking materials between floors or generations of apartments.

특히, 난연성이며 성분의 조성 상 화재가 발생하여도 EPS나 폴리우레탄과 같은 유기 보온단열재와는 달리 유해한 독성물질을 전혀 배출하지 않아 화재로 인한 치명적 폐해를 줄일 수 있다는 것이다.In particular, unlike a thermal insulation material such as EPS or polyurethane, even if a fire occurs due to the flame retardancy and composition, it does not emit harmful toxic substances at all, thereby reducing the fatal damage caused by the fire.

또한, 본 발명에 의해 제작되는 보온단열재는 고속철도 터널의 내부 소음재로부터 샌드위치판넬 내부 충진재, 건축자재, 보온단열재 등에 이르기까지 필요에 따라 모두 사용이 가능한 다용도 재생자재이다.In addition, the thermal insulation material produced by the present invention is a versatile recycled material that can be used as needed, ranging from internal noise materials of high-speed railway tunnels to sandwich panel internal fillers, building materials, thermal insulation materials, and the like.

폐패각 분말에 대한 타 첨가재의 혼입비율은 완성된 보온단열재에서 요구하는 밀도, 팽창비율, 보온단열성, 강도 등 물리적 성상에 따라 조절이 가능하므로 다양한 제원의 제품으로 생산이 가능하다.The mixing ratio of other additives to the waste shell powder can be adjusted according to the physical properties such as density, expansion ratio, thermal insulation, and strength required for the finished thermal insulation material, so that it is possible to produce products with various specifications.
