Description
본 발명은 굴 패각 폐기물을 이용하여 건축용 내외장재인 타일, 블록, 보드의 제조방법 및 그 제조 방법을 이용하여, 제조된 건축용 내외장재 타일, 블록, 보드에 관한 것이다.The present invention relates to a method for manufacturing tiles, blocks, and boards, which are interior and exterior materials for construction using oyster shell waste, and to interior and exterior materials for construction, tiles, blocks, and boards manufactured using the manufacturing method.
국내 굴 생산량은 연간 약 34만 톤(2020년 기준)이며, 패각(껍데기) 발생량은 28만 톤(82%)이고, 전 세계적으로는 435만 톤으로 누적(2019년 기준) 4,380억 톤 이 적재되어 있다. 국내 굴 패각 폐기물 중 26%만 채묘용으로 재활용되고 74%는 해양투기, 육지 야적 등으로 방치되고 있는데, 특히 국내의 굴 패각 발생의 경우 굴과 껍데기를 분리해서 굴 알맹이만 유통시키는 박신장(10)에서 패각 폐기물이 연간 28만 톤 발생된다. 또한 일반 폐기물이 아닌 산업 폐기물 분류하고, 워낙 많은 량이 배출되어 영세 사업장인 박신장(10)에서 패각 폐기물을 처리하기엔 비용적으로 불가능하다. 이에 중앙정부와 지자체에서 패각 폐기물 처리를 위해 2020년 기준 103억 5천만 원의 보조금을 지원하였는데, 이는 2016년 대비 3배가 증가하였고, 12년간 지원한 누적 보조금은 463억 5천만 원 이다.Domestic oyster production is about 340,000 tons per year (as of 2020), shell production is 280,000 tons (82%), and 4.35 million tons are accumulated worldwide (as of 2019) with 438 billion tons has been Only 26% of domestic oyster shell waste is recycled for seedling harvesting, and 74% is left unattended due to dumping at sea or land storage. ) generates 280,000 tons of shell waste annually. In addition, it is cost-effective to classify industrial waste, not general waste, and to treat shell waste at the Park Sinjang 10, which is a small business, because it is discharged in such a large amount. Accordingly, the central and local governments provided subsidies of KRW 10.35 billion as of 2020 for the treatment of shell waste, which is a three-fold increase compared to 2016, and the cumulative subsidy supported for 12 years is KRW 46.35 billion.
굴 껍데기(패각)의 주요성분은 순도 90%의 탄산칼슘(CaCO3)으로 이루어져 있으며, 인체에 유익한 성분이지만, 영원히 썩지 않는다. 어패류인 굴은 인체에 유익한 영양소가 많아 전 세계적으로 인기가 많은데, 전세계 굴 생산량의 국가 순위는 1위가 중국이며, 2위가 한국이다. 굴은 알맹이만 섭취하고 껍데기(패각)는 버려지는데, 굴 생산량 중 껍데기(패각)가 차지하는 비율이 대략 82% 이며, 굴 패각의 재활용 방안의 부제로 인한 대표적인 피해 사례로는 굴 패각에 잔존하는 부산물의 부패에 따른 악취, 침출수 유출로 인한 바다사막화와 수질 및 토양오염 그리고 자연경관 훼손 및 주거환경 피해 등 어촌의 심각한 환경문제를 야기하고 있다.The main component of oyster shells (shells) is composed of 90% pure calcium carbonate (CaCO3), which is beneficial to the human body, but does not rot forever. Oyster, a fish and shellfish, is popular all over the world because of its many beneficial nutrients to the human body. Only the kernels of oysters are consumed, and the shells (shells) are discarded. The proportion of shells (shells) in oyster production is approximately 82%, and a representative case of damage caused by the sub-plan for recycling oyster shells is by-products remaining in oyster shells It is causing serious environmental problems in fishing villages, such as odor from decay, sea desertification due to leachate leakage, water quality and soil pollution, damage to natural scenery and damage to the residential environment.
현재까지 시도된 굴 패각 재활용 방안은 굴 패각이 대부분 탄산칼슘으로 되어 있어 칼슘을 다량으로 소비하기 위한 토양의 비료, 양계용 사료, 염화칼슘, 칼슘카바이드, 석회 제품 제조 등에 주로 이용했다. 그러나 염화칼슘 등은 주로 자연에서 추출하는 방법을 이용하거나 솔베이법을 이용한 부산물로 얻는 방법이 주류로 굴 패각으로 제조할 경우 경제성이 매우 낮아진다. 굴 패각을 이용한 비료 제조 대한민국 등록특허 10-1151313 『굴껍질을 이용한 완효성 비료의 제조방법』 등 굴 패각 비료 연구 등 다양한 방안이 진행됐지만, 굴 패각 비료의 염분잔존(2% 미만)으로 인한 농작물 피해를 우려한 농가의 기피현상과 4~5년에 한번 사용하는 토양 산성화를 방지해주는 용도의 굴 패각 비료의 특성상 수요가 미비하여, 현재는 국내 모든 굴 패각 비료 생산공장들이 가동을 멈춘 상태이다. Most of the oyster shell recycling methods that have been tried so far are made of calcium carbonate, which is mainly used for soil fertilizer, poultry feed, calcium chloride, calcium carbide, and lime product manufacturing to consume large amounts of calcium. However, calcium chloride, etc., is mainly obtained by using a method extracted from nature or as a by-product using the Solvay method, and when manufactured with oyster shells, the economic efficiency is very low. Manufacture of fertilizer using oyster shells Korean registered patent 10-1151313 『Manufacturing method of slow-acting fertilizer using oyster shells』 Various measures have been conducted, such as research on oyster shell fertilizers, but crop damage due to residual salt (less than 2%) in oyster shell fertilizers Due to the nature of oyster shell fertilizer for the purpose of preventing soil acidification, which is used once every 4 to 5 years, and the avoidance of farmers concerned about oyster shell fertilizer, demand is insufficient.
이외 굴 패각을 건축재료로 사용하는 사례로 미국의 경우 굴 패각을 분쇄하여 토목공사 때 바닥 다짐재로 사용하여, 모래를 대체하는 방식으로 사용하고 있으며, 국내 사례로는 대한민국 등록특허 10-1151313 『석탄재와 패각을 이용한 보도블록 제조방법』등이 제안되어 있지만, 근본적인 문제를 해결하기 위해서는 굴 패각 폐기물 연간 발생량의 74%를 재활용 할 수 있는 방안을 마련해야 한다.In addition, as an example of using oyster shells as a building material, in the United States, oyster shells are crushed and used as a floor compaction material during civil engineering works, replacing sand. A sidewalk block manufacturing method using coal ash and shells” has been proposed, but in order to solve the fundamental problem, it is necessary to come up with a plan to recycle 74% of the annual amount of oyster shell waste.
본 발명은 상기와 같은 문제점을 해결하기 위한 것이다. The present invention is to solve the above problems.
일반적인 건축용 내외장재인 타일, 블록, 보드는 모래, 시멘트, 석고, 석재 등을 주로 혼합하여 만드는데 주로 주거, 상업, 공공시설 등에 안전, 미관, 편의, 기능성 등을 위해 이용한다. 그러나 기존의 시멘트, 모래, 석고, 석재 등을 포함한 건축용 내외장재는 경도 및 내열성 등이 우수하여, 보편적으로 사용되고 있지만, 시멘트 및 모래는 한정된 매장량과 재활용이 불가능하며, 이러한 자원의 채취를 위해서는 자연훼손이 불가피한데, 자원 채취로 얻는 경제적 이득 보다 환경적 피해가 매우 크다. 굴 패각을 건축재료로 사용하는 사례로 미국의 경우 굴 패각을 분쇄하여 토목공사 때 바닥 다짐재로 사용하여, 모래를 대체하는 방식으로 사용하고 있으며, 국내 사례로는 대한민국 등록특허 10-1151313 『석탄재와 패각을 이용한 보도블록 제조방법』등이 제안되어 있다.Tiles, blocks, and boards, which are general interior and exterior materials for construction, are mainly made by mixing sand, cement, gypsum, and stone, and are mainly used for safety, aesthetics, convenience, and functionality in residential, commercial, and public facilities. However, conventional interior and exterior materials for construction, including cement, sand, gypsum, and stone, are universally used due to their excellent hardness and heat resistance. However, cement and sand have limited reserves and cannot be recycled, and natural damage is required to collect these resources. Inevitably, the environmental damage far outweighs the economic gains from resource extraction. As an example of using oyster shells as a building material, in the United States, oyster shells are crushed and used as a floor compaction material during civil engineering works, replacing sand. A method for manufacturing a sidewalk block using a shell and a shell” has been proposed.
그러나 종래의 기술들은 굴 패각 폐기물을 주원료가 아닌 첨가제로써 첨가량이 높지 않아 굴 패각 폐기물의 처리량이 미약하고, 시멘트 및 모래 등 환경오염과 자연파괴를 발생시키는 원료를 주성분으로 사용하여, 굴 패각 폐기물을 재활용한 친환경 건축자재로 보기 어렵다.However, conventional technologies use oyster shell waste as an additive rather than the main raw material, and the amount of oyster shell waste is not high because the amount of oyster shell waste is not high. It is difficult to see it as a recycled eco-friendly building material.
