Abstract

The invention provides an ecological rehabilitation promoting snow-melting agent and a preparation method thereof .The snow-melting agent is prepared from, by mass, 10-30 parts of polyaspartic acid, 30-50 parts of humic acid, 10-30 parts of acetate and 0-20 parts of chlorine salt .Firstly, humic acid is prepared according to the mass proportion, potassium permanganate and 30% hydrogen peroxide are added, and a combined pre-oxidation reaction is conducted; after the combined pre-oxidation reaction is finished, acetate and chlorine salt are added, stirred and dissolved, and the mixture is cooled to room temperature; polyaspartic acid is added, and after the materials are evenly mixed, the mixture is directly contained in a barrel to serve as a liquid snow-melting agent or is sprayed to be prepared into a solid particle snow-melting agent .The snow-melting agent can be used for melting snow and ice, stimulating plant growth and reducing harm of chlorine salt snow-melting agents left in soil to the environment .Besides, biological degradation can be achieved, a preparation process is simple, production cost is low, and the snow-melting agent is suitable for industrial application.

Description

technical field [0001] The invention relates to the technical field of compound salts, in particular to an eco-restoration-promoting deicing agent and a preparation method thereof. Background technique [0002] In the northern cities of my country represented by Beijing, snowfall in winter not only seriously affects the traffic safety of highways and cities and the normal production and life of residents, but even threatens the safety of people's lives. Snow melting agent has become an important and necessary means for fast snow removal and ensuring traffic. Deicing agent, also known as deicing salt, lowers the freezing point of water and melts snow by adding salt to snow. According to statistics, in 2014 alone, the amount of deicing agent used in Beijing was as high as 65,000 tons, and that in Shenyang exceeded 12,000 tons. The currently widely used deicing agents are mainly chloride-type inorganic salts such as sodium chloride, calcium chloride, and magnesium chloride. ...
