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 diammonium hydrogen 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] The present invention relates to snow melting agents. Especially the environmentally friendly snow melting agent. Background technique [0002] The prior art snow melting agent mainly uses 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 highways, bridges, motor vehicles and traffic road facilities, reduce the service life, but also cause damage to the flowers, plants and trees on both sides of the highway, and cause salinization to the soil. , causing environmental pollution. [0003] In order to achieve the purpose of environmental protection, there are also some improved technologies. For example, the snow melting agent disclosed in the CN200610046356 patent application is based on at least two of the five raw materials of calcium nitrate, calcium chloride, magnesium chloride, sodium chloride and calcium hypochlorite and sodium metasil...
