Abstract
Description
본 발명은 석면 고형 안정화용 피복조성물에 관한 것이며, 구체적으로는 석면이 함유된 건축자재 내지 석면건축자재를 포함하고 있는 건축물에 석면 고형 안정화용 피복조성물을 도포하여 석면이 비산되지 않도록 하는 석면 고형 안정화 처리방법에 관한 것이다.The present invention relates to a coating composition for asbestos solid stabilization, and specifically, asbestos solid stabilization to prevent asbestos from being scattered by applying a coating composition for asbestos solid stabilization to a building including asbestos-containing building materials or asbestos building materials. It relates to a treatment method.
석면(asbestos)은 기계적인 강도가 우수하고 또한 불연성, 단열성, 내구성, 절연성, 보온성이 뛰어나 건축재료로서 방화재, 내화재, 보온재, 단열재, 지붕재(슬레이트), 전기절연재 등 여러 산업분야에서 다양한 용도로 오래 전부터 널리 사용되어 왔다.Asbestos is a building material with excellent mechanical strength and excellent incombustibility, insulation, durability, insulation and insulation. It is used for various purposes in various industries such as fireproof, fireproof, insulation, insulation, roofing (slate) and electrical insulation. It has been widely used for a long time.
그러나 석면분진을 장기간 호흡기를 통해 흡입하게 되면 석면폐(폐선유증), 폐암, 악성중피종을 유발하는 등 석면이 인체에 유해한 사실이 알려지면서 석면을 건축재 등으로 시공하는 것을 금지하고 있으며, 우리나라도 1991년부터 본격적으로 석면사용의 규제가 발표되면서 더 이상 건축물에 발포석면을 사용하는 일은 거의 없으나, 이미 오랜 전에 지하철과 같은 공공구조물, 주택, 빌딩 같은 건축물에 시공된 석면함유 건축재가 시간이 경과하면서 석면이 유출되어 비산하는 문제점이 발생하여 이들 석면함유 건축재를 해체하여야 할 필요성이 크게 대두되고 있으므로 정부에서는 2007년 “석면 관리 종합 대책”을 발표한 이래 석면 사용을 규제하고 있으며, 석면 사용 실태를 파악하기 위해 학교, 병원 등 석면 민감 시설이나 공공 건물부터 실태를 조사해 그 결과를 ‘석면 지도’로 만들어 관리하는 계획을 추진하고 있으며, 궁극적으로는 학교와 공공시설로부터 석면 함유 건축자재를 폐기할 계획을 진행하고 있다.However, when asbestos dust is inhaled through the respiratory organs for a long time, asbestos is known to be harmful to the human body, such as asbestosis (pulmonary nephropathy), lung cancer, and malignant mesothelioma. As the regulations on the use of asbestos have been announced in earnest, the use of foam asbestos is rarely used anymore.However, asbestos-containing building materials, which have been installed in public structures such as subways, houses, and buildings for a long time, Since there is a problem of spilled and scattered materials, the necessity of dismantling these asbestos-containing building materials is increasing. The government has regulated the use of asbestos since the announcement of the "Asbestos Management Comprehensive Measures" in 2007. Investigate the actual condition of asbestos-sensitive facilities and public buildings such as schools and hospitals. It is pursuing a plan to create and manage the results as "asbestos-map ', and ultimately has plans to proceed with the disposal of asbestos-containing building materials from schools and public facilities.
상기 석면 관리 종합 대책은 석면 함유 건축자재를 폐기하는 방향으로 추진되고 있으나, 석면함유 건축자재를 폐기하기 위해서는 건물, 빌딩 등으로부터 석면함유 건축재를 해체하여야 하지만, 석면 해체작업은 공사기간이 상당이 소요되는 고비용의 작업이며 또 발생하는 폐기물의 처리 및 해체과정에서 석면의 비산으로 인하여 주변 환경을 오염시켜는 문제로 2차 공해를 유발하거나 작업장의 작업환경을 악화시켜 작업자의 건강을 해칠 우려가 있으므로 석면함유 건축자재를 해체하는 작업과정은 석면의 비산방지에 대하여 엄격하게 규제하고 있다.The comprehensive measures for asbestos management are being promoted to dispose of asbestos-containing building materials. However, in order to dispose of asbestos-containing building materials, asbestos-containing building materials must be dismantled from buildings, buildings, etc. Asbestos is an expensive operation, and as a result of polluting the surrounding environment due to asbestos scattering in the process of dismantling and dismantling of waste, it can cause secondary pollution or worsen the work environment of the workplace, which may damage workers' health. The process of dismantling building materials is strictly regulated against the prevention of asbestos scattering.
석면의 안전관리는 비산되는 상황을 만들지 않고 완전하게 제거하여 안정되게 폐기하는 것이 최선이지만 석면 함유 건축자재의 해체 및 폐기에 따른 석면의 안전관리는 고비용과 내용년수가 상당히 남은 건축물의 경우 복구공사에 따른 비용발생, 자원의 재활용등과 관련하여 단점이 있으므로 이러한 문제점에 대한 개선방안으로 건축물에서 석면함유 건축자재를 해체하지 않으면서 석면건축자재의 안정화하는 방법으로 석면 고형 안정화 기술이 개발되고 있다.Asbestos safety management is best to be removed completely without creating a scattering situation, but asbestos safety management due to the dismantling and disposal of asbestos-containing building materials is necessary for restoration work in the case of buildings with high cost and long service life. As a result of the cost and recycling of resources, asbestos solid stabilization technology has been developed as a method of stabilizing asbestos building materials without disassembling asbestos-containing building materials in buildings.
상기 석면 고형 안정화 기술과 관련한 선행기술로 예를 들면, 국내 등록특허공보 등록번호 10-0981944호에 석면이 함유된 건축자재를 해체하지 않고 건축자재의 표면에 도포하여 석면을 안정화시키는 탄산칼슘, 아크릴계 수지, 천연오일로 이루어진 석면 고형 안정화 용제를 개시하고 있으며, 또 국내 등록특허공보 등록번호 1194675호에는 석면 함유 자재의 표면에 경화제 함유 에폭시수지와 시멘트로 이루어진 도포제를 2회에 걸쳐 도포하고, 양생시키는 석면 고형 안정화 처리방법을 개시하고 있으나 이들 선행기술은 유기고분자 수지를 건축물의 실내 등에 사용하는 것이므로 유기고분자 수지로부터 휘발성 유기화합물(Volatile Organic Compound ; VOC)의 발생으로 인체에 손상을 주거나 건강을 해치는 문제점이 있을 수 있다. As a prior art related to the asbestos solid stabilization technology, for example, in the domestic registered patent publication No. 10-0981944, calcium carbonate, acryl-based to stabilize the asbestos by applying to the surface of the building material without disassembling the building material containing asbestos Asbestos solid stabilization solvent consisting of resin and natural oil is disclosed, and in Korean Patent Publication No. 1194675, a coating agent consisting of a curing agent-containing epoxy resin and cement is applied to the surface of an asbestos-containing material twice and cured. Asbestos solid stabilization treatment method is disclosed, but these prior art is to use the organic polymer resin in the interior of the building, such as the problem of damaging the human body or harming the health by the generation of volatile organic compound (VOC) from the organic polymer resin This can be.
또한 국내 등록특허공보 등록번호 10-1146488호에 시공된 석면함유 자재를 해체, 철거하지 않고 안정화제를 스프레이하여 비산을 방지할 수 있는 이산화규소(SiO2), 붕산(H3BO4) 및 수산화칼륨으로 이루어진 스프레이형 석면 안정화제를 개시하고 있으나, 이러한 선행기술은 무기성분의 부착력 및 접착력이 약하여 안정화제의 이탈 등으로 석면의 안정화 효과가 지속되지 못하여 수시로 안정화제를 스프레이 하는 문제점이 있다.In addition, a spray consisting of silicon dioxide (SiO2), boric acid (H3BO4) and potassium hydroxide, which can prevent scattering by spraying a stabilizer without dismantling or dismantling the asbestos-containing material constructed in Korea Patent Publication No. 10-1146488 Although the asbestos stabilizer is disclosed, such prior art has a problem in that the stabilizing effect of asbestos cannot be maintained due to the detachment of the stabilizer due to the weak adhesion and adhesion of the inorganic component, and there is a problem in spraying the stabilizer from time to time.
본 발명은 석면과의 친화성이 높은 무기계 접착제 및 기능성 세라믹 및 천연물의 조합에 의해 상기한 선행기술의 문제점을 개선함으로써 본 발명을 완성하였다.The present invention has completed the present invention by ameliorating the above-mentioned problems of the prior art by the combination of an inorganic adhesive with high asbestos, a functional ceramic and a natural product.
본 발명은 건축물에서 석면함유 건축자재를 해체하지 않으면서 석면함유 건축자재를 안정화하는 석면의 고형 안정화용 피복조성물 및 이를 이용한 석면의 고형 안정화 처리방법의 제공을 목적으로 하며, 보다 상세하게는 석면에 친화성이 높은 무기계 바인더성분 및 천연물질의 사용에 의해 인체에 유해한 휘발성 유기성분(Volatile Organic Compound ; VOC) 및 환경호르몬 등의 발생의 우려가 없는 석면 고형 안정화용 피복조성물을 이용하여 석면함유 건축자재에 도포함으로써 건축물에서 석면함유 건축자재를 해체하지 않으면서 석면함유 건축자재를 안정화하는 석면의 고형 안정화 처리방법의 제공을 목적으로 하는 것이다.The present invention aims to provide a solid stabilization coating composition for asbestos stabilizing asbestos-containing building materials without disassembling asbestos-containing building materials in buildings and as a method of solid stabilization of asbestos using the same. Asbestos-containing building materials using asbestos solid stabilizing coating composition that does not cause volatile organic compounds (VOCs) and environmental hormones that are harmful to the human body by using high affinity inorganic binder components and natural substances It is an object of the present invention to provide a solid stabilization treatment method for asbestos that stabilizes asbestos-containing building materials without dismantling asbestos-containing building materials in buildings.
본 발명에서 목적하고 있는 과제를 해결하기 위한 수단으로서 본 발명의 석면 고형 안정화용 피복조성물은 물 100중량부에 대하여 콜로이달실리카, 소듐실리케이트 및 포타슘실리케이트로부터 선택되는 1이상의 실리카계 무기바인더 30 ~ 40중량부, 알루미나졸 10 ~ 15 중량부, 인산칼륨 0.5 ~ 2 중량부, 벤토나이트 5 ~ 10중량부, 탄산칼슘 10 ~ 15중량부, 피톤치드 10 ~ 15중량부 및 향나무분말 10 ~ 15중량부로 조성되는 것으로 이루어진다.Asbestos solid stabilizer coating composition of the present invention as a means for solving the object aimed at the present invention is selected from colloidal silica, sodium silicate and potassium silicate based on 100 parts by weight of water 30 ~ 40 Part by weight, 10 to 15 parts by weight of alumina sol, 0.5 to 2 parts by weight of potassium phosphate, 5 to 10 parts by weight of bentonite, 10 to 15 parts by weight of calcium carbonate, 10 to 15 parts by weight of phytoncide and 10 to 15 parts by weight of juniper powder It consists of
