Snow-melting agent and preparation method thereof

Abstract

The invention relates to the technical field of snow-melting agents, and relates to a snow-melting agent. The snow-melting agent is prepared from magnesium chloride, anhydrous calcium chloride and silicate according to the mass ratio of 1:(0.1-0.5):(0.1-0.5). The invention further provides a preparation method of the snow-melting agent; the preparation method comprises the following steps: I, crushing anhydrous calcium chloride until the practical size of the crushing anhydrous calcium chloride is 1-2 mm; II, mixing the magnesium chloride, the anhydrous calcium chloride and the silicate according to the mass ratio of 1:(0.1-0.5):(0.1-0.5), and uniformly stirring. The novel snow-melting agent provided by the invention is wide in raw material resource, low in cost and water-absorbing and anti-sliding. As the tailings generated after a potash fertilizer is prepared are adopted as a constituent component magnesium chloride, the waste resource is utilized, the environment can be protected, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of snow melting, in particular to a snow melting agent and a preparation method thereof. Background technique [0002] Urbanization and highwayization are important symbols of social progress and development. Some technologically advanced countries have developed urban and highway transportation rapidly, and automobiles have become the main means of transportation. Therefore, urban traffic and highway traffic occupy a special and important position in the development of the national economy. [0003] Traffic difficulties caused by winter snow, especially endangering personal safety, improper or untimely handling, can affect the economic development of cities, regions and even countries, and at the same time affect the normal life of the people, and even cause partial "paralysis" and large-scale "accidents" happened. Therefore, melting ice and snow in time has great social, economic and national defense sig...

AI Technical Summary

Problems solved by technology

[0007] Among the chlorine salt deicing agents, sodium chloride and calcium chloride are relatively low in cost, but cause serious environmental pollution; non-chlorinated deicing agents are less polluting to the environment, but the cost is high and the preparation process is relatively complicated. At present, it is only used in specific occasions, such as airports, highways, etc.; the environmental pollution of mixed deicing agents is between chlorine salts and non-chlorine salts, and the process is relatively complicated and the cost is high

Moreover, the vast majority of the current situation is that a large amount of water is formed on the road surface after the ice and snow are melted by using a deicing agent, which brings inconvenience to traffic.
