Abstract

본 발명은 강설시 노면의 융설 및 결빙방지 조성물에 관한 것으로, 특히 금속의 부식을 억제하는 특성을 갖는 융설 및 결빙방지 조성물에 관한 것이다. 동절기에 노면에 쌓인 눈을 제거할 목적으로 산포하는 융설 및 결빙방지제로는 염화칼슘,염화나트륨,염화마그네슘 등의 염화물이 널리 사용되어 오고 있다. 그 밖에 뇨소,아인산 등이 융설제로 사용되고 있다. 종래의 융설제로 널리 사용되고 있는 염화칼슘,염화나트륨,염화마그네슘 등의 염화물은 빗물이나 지하수에 비하여 금속을 40배 빨리 녹슬게 하는 문제점이 있다. 이와 같은 종래의 융설제에 의한 금속의 부식 촉진 문제는 자동차,교량 등의 철 구조물 등의 부식을 촉진시켜 자동차 및 교량 등의 수명을 단축시킴으로써 경제적 손실을 야기시킬 뿐만 아니라 교량의 안전관리에 치명적인 악영향을 끼치게 된다. 본 발명은 종래의 융설제에 통상의 부식억제제를 첨가함으로써, 종래의 융설제가 갖고 있는 부식 문제를 해결하여 금속의 부식을 억제하는 특성을 갖는 융설 및 결빙방지 조성물을 제공케 된 것이다.The present invention relates to a snow melting and freezing composition of the road surface during snowfall, and more particularly, to a snow melting and freezing composition having a property of inhibiting corrosion of metals. Chloride, such as calcium chloride, sodium chloride, and magnesium chloride, has been widely used as a snow melting and freezing agent for the purpose of removing snow accumulated on the road during the winter season. In addition, urine and phosphorous acid are used as a snow melting agent. Chloride, such as calcium chloride, sodium chloride, magnesium chloride, which are widely used as a conventional snow melting agent, has a problem of rusting metal 40 times faster than rainwater or groundwater. This problem of accelerated corrosion of metals by the conventional snow melting agent not only causes economic losses by promoting corrosion of steel structures such as automobiles and bridges, and shortens the life of automobiles and bridges, but also has a detrimental effect on the safety management of bridges. Will cause. The present invention solves the corrosion problem of the conventional snow melting agent by adding a conventional corrosion inhibitor to provide a snow melting and freezing composition having a property of suppressing corrosion of metal.
