Corrosion-inhibition environment-friendly snow melting agent

Abstract

The invention discloses a corrosion-inhibition environment-friendly snow melting agent, belonging to the technical field of snow melting agents. The snow melting agent is prepared from the following raw materials in parts by mass: 1-100 parts of betaine hydrochloride mother liquor, 10-13 parts of liquid alkali, 60-70 parts of calcium chloride, and 1-5 parts of a corrosion inhibitor, wherein the corrosion inhibitor is prepared from amino acid, thiourea, sodium tartrate, sodium hexametaphosphate, sodium gluconate and trisodium citrate. The corrosion-inhibition environment-friendly snow melting agent not only reduces the corrosion rate of the snow melting agent, but also contains an amino compound which can be used as nitrogen fertilizer, at the same time, the deicing ability of the snow melting agent is enhanced, the freezing point of the snow melting agent is lowered, the amino acid in the corrosion inhibitor is easy to degrade, and the environmental pollution is lowered.

Description

technical field [0001] The invention belongs to the technical field of snow-melting agents, and in particular relates to a corrosion-inhibiting and environment-friendly snow-melting agent. 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. , causing 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 temperature. Sprinkling an appropriate amount of deicing agent...

AI Technical Summary

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 deicing effect is greatly affected by the ambient temperature, the snow melting efficiency is low, and its price is expensive. Generally, it is only used in airports and large squares. and other important places
