Problems solved by technology

Corrosion inhibitors are mostly nitrite, which can only be used for reinforced concrete bridges, and once infiltrated into the soil, they will pollute the groundwater
The traditional environment-friendly deicing agent uses calcium magnesium acetate as the main component. Although it has the characteristics of non-pollution and environmental protection, the effect of deicing and snow is greatly affected by the ambient temperature, the efficiency of melting snow is low, and its price is expensive. Generally, it is only used in airports, large-scale Use in important places such as squares

Abstract

The invention relates to an organic / inorganic composite environment-friendly snow melting agent. The snow melting agent comprises 30 to 90 parts of formate, 25 to 75 parts of nitrate, 0.5 to 10 parts of sulfate, 0.5 to 15 parts of acetate, 1 to 20 parts of urea and 5 to 25 parts of calcium carbonate. The snow melting agent has a high snow melting speed and a good effect. Compared with the traditional chloride snow melting agent, the snow melting agent has low corrosivity on roads and bridges and low harmfulness on plants. Compared with the traditional calcium magnesium acetate snow melting agent, the snow melting agent is relatively low in cost. A preparation method for the snow melting agent is simple and practicable and applicable to large-scale mechanized operation, and has high popularization and application prospects.

Description

technical field [0001] The invention relates to an organic-inorganic composite environment-friendly deicing agent, in particular to an environmentally friendly deicing agent which is reasonably compounded with formate, nitrate, urea and other components. Background technique [0002] Snowfall in cold areas brings great inconvenience to people's life and travel, and easily induces traffic accidents, especially on expressways, and expressways may be forced to close due to snow accumulation or icing. cause huge economic losses. Therefore, how to quickly remove snow and prevent freezing to ensure the smooth flow of highways undoubtedly has important economic and social significance. [0003] The current snow removal methods mainly include artificial snow removal, mechanical snow removal and deicing agent snow removal. However, the efficiency of manual snow removal and mechanical snow removal is low, and it is difficult to remove it. The remaining snow will freeze again at low t...
