Description
본 발명은 친환경 부식방지용 이형제 제조방법에 관한 것으로서, 보다 상세하게는 기존 휘발성 유기화합물(VOCs)을 대체하여 식물성 합성오일을 사용함에 따라 친환경적이면서 인체에 무해하고, 고분자를 첨가하여 방청성능이 향상된 바인더와 식물성 합성오일의 배합비를 최적화하여 이형성 및 내식성이 크게 향상된 친환경 부식방지용 이형제 제조방법에 관한 것이다.The present invention relates to a method for manufacturing an eco-friendly anti-corrosion release agent, and more particularly, to a binder that is environmentally friendly, harmless to the human body, and has improved anti-rust performance by adding a polymer by using vegetable synthetic oil in place of existing volatile organic compounds (VOCs). It relates to a method for manufacturing an eco-friendly anti-corrosion release agent with significantly improved release properties and corrosion resistance by optimizing the mixing ratio of and vegetable synthetic oil.
일반적으로 건축물 공사에서 거푸집은 전체 공사비면에서 약 10%, 그리고, 전체 공사기간면에서 25%를 차지할 정도로 비중이 크고, 그 밖에 품질, 안전 측면에서도 매우 중요한 공사 중 한 부분을 차지하고 있다.In general, in building construction, formwork accounts for about 10% of the total construction cost and 25% of the total construction period, and it is one of the very important constructions in terms of quality and safety.
건축물을 공사하는 경우, 제작하고자 하는 콘크리트 구조물의 형상에 맞도록 알루미늄과 같은 금속 거푸집을 만든 다음, 이 거푸집 속에 콘크리트를 주입한 후 콘크리트가 양생된 후에는 거푸집을 분리(탈형)하게 된다.In the case of constructing a building, a metal formwork such as aluminum is made to fit the shape of the concrete structure to be manufactured, concrete is injected into the formwork, and after the concrete is cured, the formwork is separated (demolded).
이와 같이, 거푸집을 분리하는 과정에서 콘크리트와 거푸집 간의 결합력에 의해 거푸집이 쉽게 분리되지 않거나 또는 콘크리트의 일부가 떨어져나가 매끄러운 표면마감이 어려우며, 그 떨어져 나간 부분을 수작업으로 일일이 메워야 하므로 공사기간과 공사비용을 상승시키는 요인이 된다.In this way, in the process of separating the formwork, the formwork is not easily separated due to the bonding force between the concrete and the formwork, or a part of the concrete falls off, making it difficult to finish the smooth surface, and the separated parts must be manually filled, which reduces the construction period and construction cost. becomes a factor that increases
이와 같은 문제점을 해결하기 위해, 거푸집의 내부 표면에 이형제(박리제)를 도포하는데, 이 때 박리제로서 폐유, 윤활유, 등유, 경유 등을 단독으로 사용하거나 이에 적당량의 점착제를 용해시킨 것을 사용하고 있다.In order to solve this problem, a release agent (release agent) is applied to the inner surface of the formwork. At this time, waste oil, lubricating oil, kerosene, light oil, etc. are used alone or an appropriate amount of adhesive is dissolved as the release agent.
그러나, 상기와 같은 석유 성분을 함유하는 이형제는 화재위험성이 있을 뿐 아니라, 석유 성분에 포함된 휘발성 유기화합물(Volatile Organic Compounds, VOCs)이 인체에 암을 유발하는 요인으로 작용한다.However, the release agent containing petroleum components as described above has a fire hazard, and volatile organic compounds (VOCs) contained in petroleum components act as a factor inducing cancer in the human body.
또한, 위와 같은 휘발성 유기화합물은 산화과정을 통해 오존과 같은 이차 생성 물질들을 만들어내기 때문에 질소산화물과 함께 광화학 스모그를 일으키는 주요원인으로 작용할 뿐 아니라, 기체상 반응을 최종적으로 거친 휘발성 유기화합물은 CO2와 같은 온실가스를 배출하는 문제점이 있다.In addition, since the above volatile organic compounds produce secondary substances such as ozone through an oxidation process, they act as a major cause of photochemical smog along with nitrogen oxides . There is a problem of emitting greenhouse gases such as
따라서, 최근 기후변화를 막기 위해 탄소중립 정책을 추진하는 국제사회의 노력에 부응하면서, 작업자의 건강을 해치지 않으면서 안전하게 사용할 수 있는 친환경 이형제의 개발이 절실하게 요구되고 있는 실정이다.Therefore, the development of an eco-friendly release agent that can be safely used without harming the health of workers is urgently required while responding to the efforts of the international community to promote carbon neutral policy to prevent recent climate change.
