Abstract

The invention relates to an environment-friendly deicing agent and a production method thereof. The production method of the environment-friendly deicing agent of the invention comprises the steps of cyclization liquid-solid-liquid separation, catalytic oxidation treatment, potassium hydroxide aqueous solution treatment, evaporation concentration and the like. The liquid environment-friendly deicing agent and the solid environment-friendly deicing agent of the present invention fully meet the requirements of GB / T 23851‑2017 "Snowmelting Agent" regarding the ability to melt snow and ice and the corrosion rate of carbon steel. The method for producing an environment-friendly deicing agent from the cyclization liquid produced in the production process of glycerin-based epichlorohydrin has the advantages of simple process flow, easy operation and control, effective utilization of waste resources, obvious social and economic benefits, and environmental friendliness.

Description

【Technical field】 [0001] The invention belongs to the technical field of resource utilization of chemical production waste. More specifically, the present invention relates to an environment-friendly deicing agent, and also relates to a production method of the environment-friendly deicing agent. 【Background technique】 [0002] Snow and ice on roads in winter has always been a major problem plaguing road traffic. Because the road surface is covered with ice and snow, the friction between the tires and the ground decreases, which can easily cause traffic accidents, and in severe cases, it will cause road traffic paralysis, and even cause heavy losses of life and property. In practice, high-level snow removal in winter mainly relies on mechanical snow removal and snow melting agent technology to ensure the rapid opening of traffic after snow. Snow melting agent is irreplaceable by other methods because of its high snow melting efficiency, good effect, easy operation, good an...
