강재 표면에 형성된 도막은 시간의 경과에 따라 외기에 의해 열화되어 재도장이 필요함에 따라 강재의 보호를 위해서 강재의 표면에 형성된 페인트를 제거할 필요가 있다.The coating film formed on the surface of the steel material is deteriorated by external air over time and requires repainting, so it is necessary to remove the paint formed on the surface of the steel material for protection of the steel material.
종래의 강구조물의 페인트를 제거하는 방법으로는 여러 가지 기존의 재래식 공법들이 있는데 이중 연마제를 사용하는 핸드글라인더 방식은 폐기물 처리가 곤란하고, 장비조작의 실수가능성이 많아 작업자의 안전성과 환경적 위해요소가 많을 뿐만 아니라 연마면이 기존의 강재 표면과 일치되지 않기 때문에 후처리 작업이 용이하지 않다고 하는 문제점이 있었고, 샌드, 쇼트블라스트 방법 및 고압 물분사 방법은 소음이 심하고 녹, 페인트 등이 완벽하게 제거되지 않을 경우 재도장 후 균열 및 탈락으로 인한 하자발생 우려가 크며 작업효율이 좋지 않은 문제점이 있으며, 그라인더에 의한 제거방식은 사실상 도료를 파쇄하거나 갈아내면서 제거하도록 이루어진 구성이기 때문에 도료의 파쇄시 다량의 분진이 발생될 수밖에 없었고, 이로 인해 상기 분진의 저감을 위해 물을 뿌리는 등의 작업이 추가로 필요할 뿐 아니라 소음이 심하게 발생될 수밖에 없다는 불편함이 있었다.There are several conventional methods for removing paint from conventional steel structures. However, the hand grinder method using double abrasives is difficult to dispose of wastes, and there is a lot of possibility of making mistakes in equipment operation, so safety and environmental risks to workers There was a problem that post-treatment work was not easy because there were many elements and the polished surface did not match the existing steel surface. If not removed, there is a high risk of defects due to cracks and drop-offs after repainting, and there is a problem with poor work efficiency. of dust was inevitably generated, and due to this, it was inconvenient that work such as spraying water was additionally required to reduce the dust, and that noise was inevitably generated severely.
이에 대해 한국등록특허 제10-2047887호(발명의 명칭 : 페인트 제거제 및 이를 이용한 페인트 제거방법 (2019.11.25))에 의하면 메톡시메틸 메틸에테르(Methoxymethyl methyl ether) 10 - 20 중량 %, 1-에틸-2-피롤리디논(1-Ethyl-2-Pyrrolidinone) 5 - 15 중량 %, 디옥솔란(Dioxolane) 20 - 30 중량 %, 히드록시프로필셀룰로스(Hydroxypropyl cellulose) 0.1 - 1 중량 %, 디메틸에테르 (Dimethyl ether) 40 - 50 중량 % 로 구성된 조성물로 구성된 페인트 제거제와 이를 이용한 페인트 제거공법은 (1) 페인트 제거제를 밀봉된 상태로 준비하는 준비단계; (2) 도막 면적 1 제곱미터당 최소 0.16리터에서 최대 0.25리터를 사용하여 붓이나 로울러로 상기 페인트 제거제를 제거 할 페인트 도막 위에 도장하는 도장 단계; (3) 페인트 도막이 부풀어 오를때까지 4 - 6 분 대기하는 대기 단계; (4) 스크래퍼나 헤라를 이용하여 부풀어 오른 페인트 도막을 긁어내 도장표면으로부터 분리해내는 분리 단계; 및 (5) 긁어낸 표면을 세척 또는 세정하는 클리닝 단계(S500);로 구성되는 페인트 제거제 및 이를 이용한 페인트 제거공법에 관한 것인데, 기존의 페인트 제거법에 비해 분진이 사방에 날리지 않아 기존 기술에 비해 작업성이 비교적 우수하다고 볼 수 있으나, 도포후 발포시간이 비교적 길어 비록 방진마스크와 산업용 안전 고글과 안전복장을 갖췄다 하더라도 미세하나마 작업자로 하여금 휘발성 유기화합물(VOC)에 노출되는 시간이 길어져 작업자의 건강을 해칠수 있으며, 전반적으로 시공시간이 길어짐은 물론 작업성면에서 개선할 점이 분명히 있는 기술이라 사료된다.In this regard, according to Korean Patent Registration No. 10-2047887 (Title of the invention: paint remover and paint removal method using same (Jan. 1, 2019)), 10 - 20 wt% of methoxymethyl methyl ether, 1-ethyl -2-pyrrolidinone (1-Ethyl-2-Pyrrolidinone) 5 - 15 weight %, dioxolane 20 - 30 weight %, hydroxypropyl cellulose (Hydroxypropyl cellulose) 0.1 - 1 weight %, dimethyl ether (Dimethyl) A paint remover composed of a composition composed of 40 - 50% by weight of ether) and a paint removal method using the same include (1) a preparation step of preparing the paint remover in a sealed state; (2) a coating step of applying a minimum of 0.16 liters to a maximum of 0.25 liters per square meter of the coating film area and applying the paint remover to the paint film from which the paint remover is to be removed with a brush or roller; (3) waiting step of waiting 4 - 6 minutes until the paint film swells; (4) a separation step of scraping the swollen paint film using a scraper or spatula to separate it from the painted surface; and (5) a cleaning step (S500) of washing or cleaning the scraped surface; relates to a paint remover comprising of and a paint removal method using the same, but compared to the existing technology, dust is not blown everywhere compared to the existing paint removal method. Although it can be seen that the performance is relatively good, the foaming time after application is relatively long, so even if equipped with a dust mask, industrial safety goggles, and safety clothing, the exposure time to volatile organic compounds (VOCs) is prolonged, and the worker's health is reduced even if it is equipped with a dust mask, industrial safety goggles, and safety clothing. It can be harmful, and it is considered to be a technology that has clear points for improvement in terms of workability as well as lengthening the overall construction time.
