Abstract

The invention relates to an environment-friendly snowmelt agent which comprises the raw materials by weight percentage: 60 to 80 of tetrahydrate calcium nitrate, 8 to 15 of monohydrate calcium acetate, 4 to 7 of tetrahydrate magnesium acetate, 1 to 4 of potassium nitrate, 4 to 8 of potassium acetate, 2.5 to 5 of monoammonium phosphate and 0.5 to 1 of anticaking agent. The invention is harmless to the growth of plants, such as flowers, grasses, trees and crops, does not pollute fishes, does not damage the growth of the fishes, does not erode steel and fully achieves the snowmelt and environmental-protection requirements.

Description

technical field [0001] What the present invention relates to is deicing agent. Especially the environment-friendly deicing agent. Background technique [0002] The prior art deicing agent mainly adopts sodium chloride as the main raw material. Although the purpose of snow removal is achieved, it is highly corrosive, which will not only cause serious corrosion to roads, bridges, motor vehicles and traffic road facilities, reduce the service life, but also cause damage to flowers and trees on both sides of the road, and cause salinization of the soil. , causing environmental pollution. [0003] Also have some improved technologies for reaching environmental protection purpose, as the disclosed deicing agent of CN200610046356 patent application is to be at least two in five kinds of raw materials of calcium nitrate, calcium chloride, magnesium chloride, sodium chloride, calcium hypochlorite and sodium metasilicate, sodium metasilicate, Composition of at least 1-2 combination...
