Environmentally safe and low corrosive de-icers and a method of manufacturing same

The present invention relates to environmentally safe and low corrosive de-icers and a method of manufacturing same. According to the present invention, the de-icers comprise calcium chloride (CaCl .2H O) as an active ingredient, a stabilizer (such as those used in foods) and a vegetable calcium preparation as additives for anti-corrosion, and a soil property improver as an ice-melting accelerator. Therefore, the present invention provides the de-icers having much improved anti-corrosion properties for metals such as steel structures as compared to conventional low corrosive de-icers, enabling to eliminate harmful damage to environment by using ingredients known as environmentally safe to plants and soils, and also enabling to mix the ingredients of the compositions more uniformly during manufacturing process, while still retaining the essential property of fast dissolution as a de-icer by introducing a system to optimize conditions such as temperature, mixing ratio, mixing speed and duration of mixing. The present invention relates to environmentally safe low corrosive de-icers and the manufacturing method thereof, and more particularly, to environmentally safe low corrosive de-icers and the manufacturing method thereof, wherein said de-icers comprise calcium chloride (CaCl.2HO) as an active ingredient, along with a food stabilizer and a vegetable calcium as additives for anti-corrosion and a soil property improver as an ice-melting promoter thus having a much improved anti-corrosion property for metal such as steel structure as compared to conventional low de-icers, enabling to eliminate the danger of environmental contamination by using ingredients environmentally safe to plants and soils, and also enabling to mix the ingredients of the composition more uniformly during manufacture while retaining the essential property of fast solubility as a de-icer by introducing a system which can optimize temperature, mixing ratio, mixing speed and duration of mixing.
